Cardiac Rupture in Acute Myocardial Infarction

INTRODUCTION
Left ventricular free wall rupture (FWR) is an infrequent complication in patients with acute myocardial
infarction (2-4%) but it carries a high mortality due to sudden death secondary to pericardial tamponade
(1-8). Its true incidence remains unknown because most studies refer to autopsy series (4,5,8-11). In
addition, most series include also patients with FWR transferred from other centers (4,5,7,8). It is
estimated, however that it may account for 5-24% all in-hospital deaths related to AMI (4,6,12,13) and
this proportion is clearly higher when we refer to patients with a first ST segment elevation myocardial
infarction where it can be 20-30%, particularly among those older than 70 years (14). These figures relate
to patients who die of cardiac tamponade or who are operated but it is likely that an imprecise number of
patients may present self-limited forms of FWR (8,15) while in others FWR presents as a sudden and
unwitnessed death that is erroneously categorized as "asystole or arrhythmic death".
CLINICAL AND ELECTROCARDIOGRAPHIC FEATURES
It is known that FWR is a complication of the elderly patient, generally older than 55 years, with an
average age 65-70 years (1,3,4,5,9,16,17), and, in contrast to relatively old reports (9,11,18,19), appears
to have no gender preference (3,10,20-22), although it may seem to be more frequent among women
because of their lower incidence of AMI (4,5) ( Table 1 ). Most patients present a first ST segment elevation
myocardial infarction (2,4,9,17,18,20), without clinically apparent heart failure (2,17,18,20) and with an
infrequent history of angina pectoris (2,17,20,23). The incidence of diabetes is not particularly high in
contrast with the increased incidence of arterial hypertension, which is often higher than 50%,
(1,5,6,9,18,20). These patients present a rather prolonged episode of anginal pain, often lasting longer
than 6 hours (1,2,4,5,10,11,21,24), or of shorter duration of pain but that has been preceded by other
episodes longer than 30-60 minutes (21). Rather frequently they have a delayed hospitalization
(2,12,18,21) often because of a misdiagnosis of their AMI or because of a silent AMI presenting as acute
pericardial tamponade. Additional triggering factors for development of a FWR are the presence of
maintained arterial hypertension (=>150 mm Hg) during the first 10-24 hours of the AMI and/or the
performance of undue physical efforts, such as persistent coughing, vomiting or agitation (2,1012,18,21,25) ( Table 2 ).
FWR generally develops in patients without previous myocardial infarction, nearly 90% (5,17 -20),
although histologically the incidence of an old necrosis may be somewhat higher (20). This in part
accounts for the infrequent presence of overt heart failure associated with FWR ( 17,18,20) as well as for
the fact that infarct size, although variable, is generally not large ( 9,18-20) and may be rather localized in
the lateral wall (9,18,19,26,27). On admission, the electrocardiogram is consistent with a transmural AMI
with a notably elevated ST segment which tends to persist elevated over the ensuing hours or days
(2,10,17).However, patients who present with an electrocardiographically "small" lateral AMI, in whom
control of arterial hypertension may not appear to be so important (17) should also deserve especial
attention. The presence of left ventricular hypertrophy appears to increase the risk for FWR (1,2,20).
Localization of infarction tends to be anterior (4,10,17,28), particularly in the necropsy series (3,4,7,28)
and among those who die suddenly of an acute FWR (17), hence excluding cases with subacute FWR
(10,15,22,29).
Often, FWR is preceded by chest pain similar to that of the AMI (1,2,5,10,11,19,21,30) and is frequently
associated with ST segment re-elevation and/or positivization of flat or negative T waves (2,17,31).
Reinfarction may be an explanation for some cases, particularly those with a late rupture (1,18,21,32,33),
and some studies have confirmed histologically their existence (18,21,32). Some patients already present
recurrence of pain prior to hospitalization, during 2-3 days, which may also be an indication of the
stuttering course of the infarction in some cases of FWR. On the other hand, rupture of the necrotic tissue
in itself (2,34,35) could also be a mechanism of chest pain, as well as the entrance of blood into the
pericardial cavity (1,10). In some cases, the chest pain and ECG changes with hypotension may simply
indicate extension of AMI without FWR (36,37). When hypotension develops early after the onset of pain,
within few minutes, and particularly when followed by electromechanical dissociation (2,38), however, the
possibility of a FWR is highest. More definite diagnosis of FWR, however, requires evidence of pericardial
tamponade in the echocardiogram. Moreover, late FWR may often be preceded by symptoms of
pericarditis, with or without a friction rub (10).
PRESENTING FORMS
a) According to time of occurrence.
Depending on the time of its development, FWR may be early, when it occurs within the first 48 hours,
or late, when it occurs beyond the second day ( Table 3 ). Early FWR represents 40-50% of cases
(1,5,17,20,39) but its proportion is likely to be higher when considering also those patients who die
suddenly outside of the hospital (16,40). In this initial presentation, factors such as a persistent strain in
the infarcted zone due to sustained arterial hypertension (2,9,17 -19,41) or to maintenance of ambulatory
activities (11,18,21,25), appear to be of importance. Autopsy studies have revealed that in patients with
an early FWR there is hardly any thinning of the infarcted area whereas in late FWR the infarcted tissue
has already expanded (17,25,39). Moreover, even though late FWR appears to be less affected by arterial
hypertension, undue physical exercise (2,18,21) can also contribute to this lethal complication. As
indicated, infarct extension may also be an alternative trigger of late FWR by completing the transmurality
of the infarction (18,32).
b) According to its clinical presentation.
When considering the clinical and hemodynamic manifestations, FWR may be considered acute or
subacute ( Table 3 ). There is agreement that the acute form is associated with sudden cardiac arrest
caused by electromechanical dissociation secondary to acute pericardial tamponade (3,4,5,10,17). This is
accompanied by severe cyanosis of the neck and face and intense jugular ingurgitation. Less clear,
however, is the definition of the subacute form, term coined by O'Rourke some years ago in a report of 3
cases (42). This concept initially implied cases with acute tamponade manifested by severe hypotension or
electromechanical dissociation that was temporarily reversed by resuscitative maneuvers which allowed a
surgical repair (42,43). Provided that there is no apparent mechanistic difference between an acute or a
subacute FWR that presents as electromechanical dissociation, we propose that the term subacute FWR be
reserved for cases presenting with hypotension of different severity. In contrast, the term acute should be
limited to FWR causing a cardiac arrest by electromechanical dissociation. This definition, therefore,
implies that even though both presentations may be initially successfully managed medically, the subacute
form is clearly less severe and, hence, more likely to recover. In addition, this distinction would help to
encompass the different severities among the subacute forms, which may range from severe hypotension
and syncope to forms with little or negligible hemodynamic impairment (15,43).
The presence of the subacute form has been increasingly recognized and may account for up to 30% of
all in-hospital FWR (1,5,11,12,15,24,30,42 -44). However, the existence of a subset of patients with a
"mild" subacute FWR has received little attention (43). These patients, who meet the basic FWR clinical
profile, that is, age >55 years, first transmural AMI with persistent ST segment elevation without overt
heart failure, present with a moderate to severe pericardial effusion but without hemodynamic compromise
and that is usually identified by a routine postinfarction echocardiogram. According to our experience, this
condition should clearly alert to the possibility of a "silent" subacute FWR for we have witnessed some
cases in whom the possibility of a subacute FWR was not contemplated and who subsequently died of a rerupture with tamponade confirmed in a necropsy study. Hypothetically, however, some of these
hemopericardiums, particularly those linked to mild forms of subacute FWR, could be attributed to others
causes, such as an hemorrhagic infarction or an hemorrhagic pericarditis (30,42,45,46). Necropsy
documentations of this kind of hemopericardiums, however, are very scanty (45,46) and existing reports
refer to cases, with or without tamponade, that have been operated and in whom no apparent FWR was
observed (30,42,43). Notwithstanding these interpretations (30,44-46), however, we consider that at least
in a number of these surgical cases the possibility of an overlooked healed FWR as the responsible cause,
should have been contemplated. In fact, there exist some necropsy studies of AMI with hemopericardium
in which a FWR that was not apparent macroscopically (4,17,18,44) corresponded, histologically, to a
thrombosed myocardial dissection (44,47). Moreover, some of these operated cases apparently unrelated
to a FWR, later developed a left ventricular pseudoaneurysm (48,49).
Therefore, it is our contention that some self-limited FWR are rather small and probably become open
temporarily only during bursts of arterial hypertension or increased myocardial strain. Some of them may
even just represent a stuttering oozing through a narrow fissure (22,44). The subsequent organization of
the hematoma would lead to an initial healing by fibrin deposits that would progressively evolve to a
definite healing by pericardial adhesions.
TREATMENT ( Table 4 )
Up until recently the only possible treatment for FWR was urgent (often desperate) surgery for cases
that could barely survived an acute tamponade (21,30,43,44,50,51). Since the eighties, however, there
have been several reports demonstrating that application of a large dacron pad sutured or glued to the
epicardial surface could substantially improved the surgical results (43,52-54). Moreover, the favorable
experience from our own institution with medical management in a selected group of these patients, also
confirmed by some isolated reports (8,51,55,56), with strict blood pressure control mostly with beta
blockers and extending the period of hospital rest for several days, has also contribute to broaden the
therapeutic spectrum for this complication.
Although FWR is the most frequent cause of hemopericardium during AMI, particularly when the
patient's clinical profile conforms that of recognized risk for this complication, definite clinical diagnosis of
FWR can only be obtained, with some limitations (44,47-49), through a thoracotomy or, occasionally,
through the echocardiographic (15,51) or angiographic (26,29,30,51,56) demonstration of blood leaking to
the pericardial cavity. This is the reason why, conceptually, we will consider management of
hemopericardium rather than FWR. We will distinguish hemopericardium with or without hemodynamic
compromise.
1) HEMOPERICARDIUM WITH HEMODYNAMIC COMPROMISE
a) Initial treatment:
Patients who fulfill the clinical profile of risk for FWR and who experience a sudden non-arrhythmic
hypotension unrelated to administration of betablockers or vasodilators associated with sinus bradycardia
or nodal rhythm and jugular distension, should be considered as presenting tamponade and will be treated
with fluid replacement with colloidal solutions and Dobutamine at 5-10 micg/Kg/min. As soon as possible,
an echocardiogram should be performed to assess the presence of a pericardial effusion, with or without
signs of right atrial compression. If hemodynamic recovery is readily achieved, a maintenance protocol
(see below) will be followed and the cardiac surgical team will be informed of the existence of a probable
FWR and the possibility to intervene if hemodynamic stabilization is not maintained. If there is no cardiac
surgery available the patient should be transferred to another center with these facilities. If the patient
remains hypotensive with signs of peripheral hypoperfusion, a pericardiocentesis should be carried out to
withdraw a small quantity of pericardial fluid (10-50 ml), enough to achieve hemodynamic recovery and an
adequate urine output. A second pericardiocentesis can be performed if recovery is partial or absent, or if
tamponade recurs. If following pericardiocentesis recovery is achieved and sustained the maintenance
protocol may be followed, but if recovery is unsuccessful after two pericardiocentesis, an emergent
thoracotomy should be undertaken. Surgical treatment applying a teflon (43,52,54,57) or a pericardial
(58) patch to the epicardial surface of the ruptured site with cyanoacrylate glue (54), preferably without
the use of cardiopulmonary bypass, would be the optimal choice. This may be more difficult if active
bleeding is present after opening the pericardium. In this case cardiopulmonary bypass may facilitate
patch application. Infartectomy of the rupture zone followed by a teflon-buttressed suture (53), on the
other hand, should be limited to cases in whom the use of the patch is unsuccessful, because it may
reduce excessively the size of the ventricular cavity.
When tamponade is complicated by a cardiac arrest due to electromechanical dissociation, cardiac
massage may be necessary to regain adequate pulse besides the previously referred measures. In these
instances, endotracheal intubation and mechanical ventilation may also be mandatory, and
pericardiocentesis will be frequently required before an echocardiogram can be performed. If there is no
hemodynamic recovery with all these measures, which may also include administration of epinephrine, a
desperate surgical treatment should be attempted because it may be lifesaving in some instances
(21,30,43,44,53). In patients with a slow recovery, particularly in those with large infarcts, it may be
necessary to monitor the right and left ventricular filling pressures through a Swan-Ganz catheter to
assess the hemodynamic response to therapy and the possible reappearance of tamponade.
b) Maintenance treatment
Once hemodynamic recovery has been attained, a conservative approach may follow. This includes
maintenance of blood pressure between 100-120 mm Hg to avoid undue myocardial wall strain and to
preserve urine output. In some patients with large AMI, and because of myocardial hypocontractility, use
of dobutamine with or without furosemide may still be necessary for several hours o days to maintain
adequate urine output in the absence of tamponade. As soon as possible, however, inotropic support
should be withdrawn and replaced by beta blocking agents, initially propranolol because its easier titration,
as tolerated, to reduce myocardial work as much as possible. To further avoid excessive myocardial
tension, patients bed rest should be extended to 4-8 days and undue physical efforts, such as excessive
strain during use of a commode or other isometric exercise, repetitive vomiting or coughing, should be
avoided. The routine postinfarction discharge exercise test should be postponed for the first two months.
Anticoagulant therapy should be withheld but antiaggregant therapy with low dose aspirin may probably
be continued.
The patient will be followed in the Coronary Care Unit for the first 7-10 days depending upon the
severity of the initial hypotension, the presence of an electromechanical dissociation, the magnitude of
pericardial effusion, the overall hemodynamic status and the difficulty to control of blood pressure. An
echocardiogram should be repeated every 2-4 days, depending on the hemodynamic course, to assess
changes in the pericardial effusion. If the patient presents a second episode of tamponade but arterial
hypotension is not severe, a new pericardiocentesis may be performed and if satisfactory results are
obtained, maintenance treatment may be resumed. This option could be particularly contemplated in
patients with high risk surgery because of old age, morbidity factors such as severe diabetes, peripheral
vascular disease, advanced renal or chronic pulmonary disease, previous cerebrovascular accident, large
infarction, especially of posterior localization, etc. On the other hand, if these relative contraindications are
not present and the recurrence of tamponade is severe or not readily reversed, the surgical treatment is
indicated following a new pericardiocentesis, which again should be limited to 10 -40 ml, as an attempt to
stabilize the hemodynamic condition prior to the operation.
c) Early follow-up treatment
During the first 2 months after hospital discharge, the patient should be allowed to walk but to avoid
relatively strenuous exercise, particularly isometric stress, to strictly control his o her blood pressure (=<
120/80 mm Hg) and to receive betablocker therapy as tolerated. An echocardiographic control at one
month to assess the course of pericardial effusion is advisable. In our series, of 35 patients with a strongly
suspected FWR who were managed without a surgical repair and survived the hospitalization period did not
develop a left ventricular pseudoaneurysm during a mean follow-up of 72 months and among the 5 longterm non survivors all had a non cardiac death except for one who presented progressive heart failure.
2) HEMOPERICARDIUM WITHOUT HEMODYNAMIC COMPROMISE
According to our experience, their therapeutical approach may follow the maintenance treatment and
the early follow-up treatment alluded above. A diagnostic pericardiocentesis may be useful to confirm
the existence of an hemopericardium.
Even though ours is the first prospective series of a conservative approach to FWR, that includes some
patients previously referred (15), there have been isolated reports of other cases who have also survived
without surgery (8,51,55,56). Thus, some patients with a strongly suspected FWR may be successfully
managed without operation although, clearly, in a considerable proportion of cases with FWR surgical
treatment is still the only alternative.
PROGNOSIS
The first case of FWR that was operated was reported in 1969 by Lillehei (50) and ever since there have
been several reports describing successful interventions in few cases, the majority in emergent and rather
extreme conditions (6,30,43,52,53). They represented, however, the very tip of the iceberg for most FWR
would die without operation or would be mistakenly interpreted as "arrhythmic", "asystolic" or
"unwitnessed" sudden deaths. Recognition of the subacute form since 1972 and the progressive awareness
that a less dramatic form of presentation may account for up to 30 % of all hospitalized cases of FWR
(1,5,11,12,15,24,42,43), however, has notably improved the prospects of survival of this mechanical
complication. Moreover, use of teflon patches (52,54,57) has resulted in a much better surgical outcome in
part because of its simplicity, often sparing the use of extracorporeal pump, and because the remarkable
limitation of myocardial damage by avoiding infarctectomy and/or the practice of deep sutures that are
often a potential source of subsequent tears and tamponade. Most importantly, identification of a subset of
patients who may be successfully treated without operation has additionally improved the overall survival
perspective. In our most recent experience over the last 5 years (1996-2000), of 50 consecutive patients
prospectively evaluated that developed a moderate to severe pericardial effusion shortly after an acute ST
segment elevation myocardial infarction, 34 presented tamponade and 6 were managed surgically and 28
medically. Twenty one survived (62%), 4 after a surgical repair (teflon patch) and 17 after medical
treatment. The remaining 16 did not present tamponade and all survived under medical management.
However, we believe that to achieve these or better results is of paramount importance to have a high
level of suspicion and to have readily available echocardiographic facilities to explore those patients with a
high risk clinical profile for FWR to detect early moderate or even mild pericardial effusion that might
herald subsequent tamponade and death due to re-rupture. In addition, early hospital admission and strict
control of hypertension mostly by early administration of beta blockers is likely to reduce the incidence of
this complication. Overall, use of thrombolytic agents within the first 6 hours after the onset of infarction
also tends to reduced the incidence of FWR (33,59) and, according to some preliminary evaluation, a more
relevant benefit may be derived from an early primary angioplasty (60).
SUMMARY
FWR is strongly suspected when a patient with an high risk profile, namely, age > 55 years with a first
myocardial infarction with persistent ST segment elevation, absence of overt heart failure and prolonged pain
suddenly presents hypotension or electromechanical dissociation associated with jugular ingurgitation and a
moderate to severe pericardial effusion. The term acute FWR should be restricted to patients with cardiac arrest by
electromechanical dissociation, and that of subacute should be applied to those presenting systemic hypotension of
variable severity. In patients with cardiac arrest has occurred, management includes cardiac massage, ventilatory
support, administration of inotropic agents and colloids, and practice of a pericardiocentesis. If recovery is not
attained, emergency thoracotomy with repair of the ruptured site is performed with application of a Teflon patch
glued to the epicardium, preferably without the use of cardiopulmonary by pass. If recovery is readily achieved,
however, a conservative management with blood pressure control and avoidance of physical stress may be
implemented with a close surveillance of the case by the surgical team. In patients with hypotension, initial
management will contemplate colloid infusion and dobutamine infusion and performance of a pericardiocentesis
aimed to withdraw 10-50 ml, enough to restore hemodynamic competence and urine output, and to proceed with
conservative management thereafter. If hemodynamic recovery can not be attained, the surgical treatment should
be performed.
The conservative strategy implies, in addition, that bed rest should be extended for 5 -7 days after diagnosis of
FWR has been suspected and that beta blockade therapy be instituted as soon as possible. This approach would be
particularly indicated in patients with important co-morbidity factors that greatly increase the surgical risk, such as
severe chronic lung disease, renal failure, extensive myocardial infarction, serious peripheral vascular disease, etc...
However, this modality of therapy should only be adopted in a center with surgical facilities needs to be confirmed
by careful experiences from different institutions.
