has a wide origin and a
broad and triangular
appearance.

CRISTA TERMINALIS
The crista terminalis is
Right ventricular free
a wall
ridge in the right
atrium that separates
Apex
the two components of
the right atrium, the
sinus venosus (smooth Aortic valve
muscles) and the
atrium of the AV valve
(pectinate muscles)

The Eustachian valve
is a fibromuscular web
that attached to the
opening of the inferior

MODERATOR BAND
The moderator band is
a muscular band that
extends from the
interventricular septum
to the base of the
anterior papillary
muscle in the RV
Pectinate muscles
Chordae tendinae
CONAL PAPILLARY MUSCLE
Anterior descending artery
Right coronary artery
Foramen oval
The right ventricle
contains anterior and
posterior papillary
muscles and a smaller
conal papillary muscle
The conal papillary
muscle arises from
the septal band of the
interventricular
septum
Circumflex
artery
RIGHT CORONARY ARTERY
Aortic root
Left ventricle
CONUS ARTERY
PDA
AMB
Acute marginal branch
Right coronary artery
The conus artery is
the first branch of the
right coronary artery
in 50-60% of patients
POSTERIOR DESCENDING ARTERY
Circumflex artery
Obtuse marginal branch
The coronary artery
that gives rise to the
PDA and
posterolateral branch
is referred to as the
dominant artery, with
the RCA being
dominant in Posterolateral artery
approximately 70% of
cases.
LEFT CORONARY ARTERY
LCA
LCx
RI
LAD
Right coronary artery
In 15% of patients, a
third branch (ramus
Circumflex artery
intermedius) arises at
the division of the LCA,
resulting in a
trifurcation

Right coronary artery
Anterior descending artery
Left coronary artery
CIRCUMFLEX ARTERY

OBTUSE MARGINAL BRANCH
LCA
The left circumflex artery courses
in the left atrioventricular groove
and gives off obtuse marginal
branches to the lateral left
ventricle
LCx
LAD
SINOATRIAL NODAL ARTERY
Right coronary artery
Left circumflex artery
Left coronary artery
The sinoatrial nodal
artery arises from the
RCA in approximately
58% of patients; in the Ramus intermedius artery
remaining patients it
arises from the left
circumflex artery Diagonal branches
