    abstract = "Corrosion castings of 60 human hearts were used to demonstrate that the
point of origin of the posterior interventricular artery (PIA), in
relation to the crux cordis, is responsible for its subsequent course
with respect to the posterior interventricular vein (PTV). In seven
cases (12%), the PIA appeared as the continuation of the left
circumflex, descending rightwards and on a deeper level of the PTV. In
53 cases (88%), the PIA arose from the right coronary artery (RCA) and
50 of these were selected to be classified into three groups, according
to the PIAs origin and course. In group A (29 cases, 58%) and B (seven
cases, 14%), the PIA emerged before the crux cordis and descended to
the right or left of the PN, respectively. In group C (14 cases, 28%),
it originated at, or beyond, the crux cordis and descended along the
left side of the PTV. Among the 50 cases, the PIA was found to be long
in 34 (68%), large in 32 (64%), and long and large in 29 cases (58%).
In 18 of the latter 29 cases (62%) or 36% of the 50 cases in total,
the PIA arose as a continuation of the RCA (group A) and therefore these
cases were easily accessible to interventional cardiologists and also to
surgeons, since the PIA lay on the same or on a superficial level in
relation to the PTV. This work describes and explains the variations of
the PIA and concludes that at least 36% of these may be helpful in
coronary artery angioplasty and bypass surgery. Anat. Rec. 252:413-417,
