“…A higher incidence was reported (34-36%) by Olabu et al, [43] and Miyazaki et al, [6]; and also, a lesser incidence (8-11%) [34,42,44]. This CAA has an anastomosis expression with neighbor arteries like AIA that is perceived as an isquemia morphologic protector factor originated in the right anterior ventricular wall.…”

Background: It is necessary knowing the large variability of right coronary (RCA) artery specialty for its implications in surgical procedures and clinic events. This variability is usually related to the length, branches quantity, origin and irrigated territories.Objective: To evaluate by direct examination the morphologic expression of RCA in Colombian people.Methods: RCA were measured in 221 fresh hearts by RCA ostium canalization with polyester synthetic resin that was injected in their branches.Results: The caliber of the RCA proximal segment and at the level of the acute angle of the heart was 3.42 ± 0.66 mm and 2.9 ± 0.50 mm, respectively. It ended between crux cordis and the left margin in 75.6% of specimens. Posterior interventricular artery (PIA) reached the inferior third, or the apex, or the anterior interventricular sulcus in 149 (67.4%) cases. Sinoatrial node artery (SNA) originated in the right coronary in 134 (60.6%) cases, 77 (34.9%) from circumflex artery (CxA) and from both in 10 (4.5%). Posterior right diagonal artery (PRDA) was noted in 38 (17.2%) hearts, but only 6% of the sample with long PIA, concomitantly presented the PRDA (P = 0.001). In right dominance SNA were originated from RCA in 54.7% and form CxA in 46.3% (P = 0.06).Conclusions: Caliber of the RCA and its branches is lesser than the majority of previous studies, while the PRDA frequency is slightly higher than the reported in literature.Clinical and pathological scenarios by these variations should be taken into account: hemodynamic procedures, cardiac surgery and arrhythmias from coronary occlusive disease.Descriptors: Coronary Vessels.

The branch of the ANA start in the "inverted U" segment of the RCA located in the crux cordis (73%-85%) and the rest coming from the terminal branch of the CxA [14,15].The importance of the cardiac irrigation variability in special the RCA is supported by s...

Background and ObjectivesCoronary artery anomalies are found in approximately 1% of patients undergoing diagnostic coronary angiography (CAG). Angiographic recognition of these vessels is important because of their clinical significance and importance in patients undergoing coronary angioplasty or cardiac surgery. There are fairly enough reports concerning the incidence of coronary anomalies in different geographic areas, but this is the first study among the Iranian population.Subjects and MethodsWe reviewed the database of the Catheterization Laboratory of Imam Reza and Shahid Madani Hospitals, Tabriz University of Medical Sciences, Iran. Our inquiry included all patients who referred for CAG from other hospitals, between February 2007 and April 2009. Patients with congenital heart diseases, high "take off" of coronary arteries and separate origin of the conus artery from the right coronary sinus (RCS) were excluded. In total, 6065 films were reviewed.ResultsSeventy nine (1.30%) patients were found to have coronary anomalies. Seventy five (1.24%) patients had anomalies of origin and distribution, while four (0.06%) had coronary artery fistulae. Most common anomaly was separate ostia of the left anterior descending artery and left circumflex artery, which was found in 42 patients (53.16%) with angiographic incidence of 0.69%. The next most common anomalies were anomalous circumflex artery from RCS/right coronary artery (RCA) {n=17 (21.51%)}, and anomalous RCA arising from left coronary sinus {n=6 (7.59%)}.ConclusionIn general, the incidence and pattern of coronary anomalies in our study was similar to earlier reports from different parts of the world.

“…Vieussens' ring is not angiographically demonstrable in most adults, but has been reported in the majority of adults by careful postmortem dissection [12]. When present, there is often separate conus origin but frequently occurs in its absence [14]. Collateralization via this network to a clinically meaningful extent has been reported [15, 16] when coronary artery disease is present, especially when there is severe right coronary arterial disease.…”

The embryologic origin of fistulous communications between a coronary artery and the pulmonary artery has traditionally been explained as the persistence of an immature supernumerary coronary artery with its origin in the pulmonary trunk. Although this hypothesis is consistent with the occurrence of the termination of the fistula in the posterior sinus of the pulmonary artery, it does not completely explain several morphologic and physiologic aspects. In this report, we present a case illustrating the classic anatomic features of left anterior descending artery to pulmonary artery fistulas and develop a new hypothesis of its embryologic origin and re‐emergence in adults that fully explains its angiographic appearance and clinical attributes. © 2008 Wiley‐Liss, Inc.
