Implantation for Severe Sinus Node Dysfunction Due to
Cardiac Involvement in Erdheim-Chester Disease

A
64-year-old woman was referred to the arrhythmia
outpatient clinic after she had experienced syncope
without preceding symptoms and frequent paroxysmal, near
syncopal episodes over the last 8 months. The ECG revealed
alternation of sinus bradycardia and frequent ectopic atrial
beats, normal PR interval and right bundle branch block with
consecutive repolarization abnormalities. Holter ECG
showed frequent periods of asystole up to 4.3 seconds.
Laboratory findings were normal. Pacemaker therapy for
symptomatic sinus node dysfunction was clearly indicated.
The patient’s past history revealed the diagnosis of
Erdheim-Chester disease with osseous, cutaneous, mesenteric, and right atrial involvement 22 years ago. This disease
belongs to a rare group of non-Langerhans cell histiocytosis
of unknown origin. Tissue is infiltrated by foamy histiocytes.1
The patient showed nearly pathognomonic radiographic
changes in both tibiae and femora with bilateral symmetrical
osteosclerosis of metaphyseal and diaphyseal regions with
sparing of the epiphyses (Figure 1A).2
Over the last 5 years the patient has been stable through
daily oral administration of 5 mg prednisolone.
Cardiac magnetic resonance imaging was performed to
guide placement of the pacemaker electrodes and visualize
the overall and local extent of tumor due to the known right
atrial involvement by Erdheim-Chester disease. Echocardiographic findings are shown in Figure 1B.
Nearly complete and extensive involvement of the right
atrial myocardium with thickening, septal bulge, and typical
perivascular tumor spread3 along the right coronary artery
could be demonstrated (Figures 2A and 2B). Only a small
area anterolateral of the right atrial wall was found to be less
thickened, and showed no delayed hyperenhancement (Figures
2C and 2D). This area was chosen for atrial lead placement.
Excellent pacing and sensing properties could be found.

heart using Cine-SSFP sequence (echo
time 1.57 ms, repetition time 47.1 ms,
5 mm slice thickness). B, T1 weighted
imaging (echo time 6.9 ms, repetition time
1044 ms, 5 mm slice thickness) in same
orientation. The thickening of right atrial
wall and septal bulge can clearly be seen.
Typical perivascular tumor spread (asterisk) along the right coronary artery. C, The
bright signal in T1 weighted images shows
a signal decay after fat suppression (echo
time 62 ms, repetition time 2110 ms) suggesting partially fat-containing parts of the
tumor. D, T1 weighted imaging 10 minutes
after contrast material application
(0.2 mmol per kg body weight Gadodiamide) with suppression of normal myocardium (black) shows extensive delayed
hyperenhancement indicative of granulomatosis/fibrosis in the thickened right atrial
wall (echo time 4.3 ms, repetition time 750
ms, inversion time 230 ms: arrowheads). A
small anterolateral area of the right atrial
wall is less thickened and shows no
delayed hyperenhancement (arrow). No
ventricular delayed hyperenhancement
was seen; so there was no evidence of
myocardial infarction.
