AbstractBackgroundAnatomic variations in orifices, courses, branching patterns, and abnormalities of coronary arteries could affect blood supply, hemodynamic characteristics, and clinical symptoms, and could be a risk of atherosclerosis.ObjectivesTo investigate the location and number of both coronary orifices in the aortic cusps, branching patterns of left main trunk, dominant pattern of posterior interventricular artery (PIA), prevalence of right posterior diagonal artery (RPDA), myocardial bridge, and other abnormalities.MethodsWe dissected 95 heart specimens from cadavers of Thai donors without the history of surgery, and the dominant patterns, location and number of orifices in the aortic cusps, branching patterns, origin and number of conal arteries, and occurrence of RPDA were determined.ResultsDual aortic origin of the coronary orifice was the most common condition. Anomalous 2 orifices in the left aortic cusp were found in one specimen in which the right coronary artery (RCA) arose from aortic cusp and had an interarterial course. Right dominance and trifurcated form of left main trunk were found more frequently. Most frequently 2 conal arteries were found. RPDA was found in 45% and mostly originated from RCA. The prevalence of myocardial bridge was 62% and located mostly on the anterior interventricular artery (AIA).ConclusionsThe prevalence of right dominance, RPDA, the atypical origin of RCA from the left sinus, and the prevalence of myocardial bridges was more frequent than reported by others, whereas the dual aortic origin from both cusps and the prevalence of bifurcated left main trunk was less frequent.

Congenital Coronary Artery Fistula

Congenital coronary artery fistula is an extremely rare anomaly that may involve any of the coronary arteries and any of the cardiac chambers. We report the case of a 14-year-old female patient with a symptomatic congenital coronary fistula starting from the left main coronary artery and draining to the coronary sinus. The patient underwent surgical ligation of the fistula and had an excellent outcome.

Abstract Background: With the increased training loads at very early ages in European elite youth soccer, there is an interest to analyse coronary artery remodelling due to high-intensity exercise. Design and methods: Prospective echocardiographic study in 259 adolescent elite male soccer players and 48 matched controls. Results: The mean age was 12.7 ± 0.63 years in soccer players and 12.6 ± 0.7 years in controls (p > 0.05). Soccer players had significant greater indexed left ventricular mass (93 ± 13 g/m2 versus 79 ± 12 g/m2, p = 0.001). Both coronary arteries origin could be identified in every participant. In soccer players, the mean diameter of the left main coronary artery was 3.67 mm (SD ± 0.59) and 2.61 mm (SD ± 0.48) for right main coronary artery. Controls showed smaller mean luminal diameter (left main coronary artery, p = 0.01; right main coronary artery, p = 0.025). In soccer players, a total of 91% (n = 196) and in controls a total of 94% (n = 45) showed left main coronary artery z scores within the normal range: −2.0 to 2.0. In right main coronary artery, a pattern of z score values distribution was comparable (soccer players 94%, n = 202 vs. controls 84%, n = 40). A subgroup of soccer players had supernormal z score values (>2.0 to 2.5) for left main coronary artery (9%, n = 19, p = 0.01) and right main coronary artery (6%, n = 10, p = 0.025), respectively. Conclusion: Elite soccer training in early adolescence may be a stimulus strong enough to develop increased coronary arteries diameters. In soccer players, a coronary artery z score >2.0–2.5 might reflect a physiologic response induced by multiannual high-intensity training.

Transcatheter Aortic Valve

Coronary obstruction, a rare complication of transcatheter aortic valve replacement, can be fatal. Few data exist on this phenomenon, and, to date, authors have reported only single coronary lesions. We present a case in which 2 coronary arteries obstructed immediately after transapical transcatheter aortic valve replacement. The patient was an 81-year-old woman with symptomatic severe aortic stenosis who underwent transapical transcatheter aortic valve replacement. Immediately after an Edwards Sapien XT valve was deployed, she experienced sudden cardiogenic shock resulting from obstruction of the left main coronary artery ostium and the distal left anterior descending coronary artery. The left main obstruction was caused by direct compression from a large calcified mass and the valve frame. The left anterior descending coronary artery obstruction was caused by ambient myocardial tightening and external compression around the apical sutures. Revascularization was achieved through coronary stent placement and suture removal, respectively. Our patient's case highlights the risk for coronary obstructions after transapical transcatheter aortic valve replacement, and we discuss how they can be managed.

Atherosclerosis related inflammation and plaque result in expansive remodeling of the coronary artery, a finding associated with plaque rupture and clinical events. The extent of expansive coronary remodeling in adults prior to the development of clinical disease is largely unknown. We tested the hypothesis that middle-aged adults who have subclinical coronary artery disease also have larger coronary artery diameters. Methods: Submillimeter thin slice, non-contrast cardiac CT images were obtained in 1197 black and white men and women in the Coronary Artery Risk Development in Young Adults (CARDIA) Study during the year 25 examination (2010-2011, mean age 50 years). Average coronary artery diameter(mm) and cross sectional area (mm2) were measured sequentially along the length of each vessel and averaged for the left main (LM) and proximal circumflex (LCX), left anterior descending (LAD), and right coronary (RCA) arteries. Presence/absence of coronary artery calcifications [CAC (0 versus >0 AU)] was measured independently. Multivariable linear regression models were used to examine the association of CAC with artery size. Results: Coronary diameter was larger in blacks compared to whites (p<0.05) and in men compared to women (p<.0001) following adjustment for age and study center. Presence of CAC was associated with larger diameter coronary arteries after adjustment for age, race, sex, education, height, and study center (Table, model 1). These associations remained following additional adjustment for established cardiovascular risk factors, with the exception of the left main segment (Table, model 2), and were similar for vessel area as for vessel diameter (not shown). Conclusion: Coronary arteries are larger in middle-age individuals with vs without CAC, supporting the hypothesis that atherosclerosis leads to expansive coronary remodeling. Coronary remodeling by non-contrast CT is a measure that may provide new information on cardiovascular risk and prediction of clinical cardiovascular events.

A 52 years lady presented with chest pain and shortness of breath. Chest pain was initially CCS class II and gradually CCS class III. Coronary angiogram reveals triple vessel disease for which she underwent CABG (RSVG to LAD) in December 1999. On January 2003 PTCA with stent (sirolimus - 3 x 15m m) to LCX was done. She again complaints of chest pain after a short symptom less period. Recent coronary angiogram revealed TVD with left main involvement. In this article we will describe a rare case of successful stenting in left main disease.   doi: 10.3329/uhj.v5i1.3441 University Heart Journal Vol. 5, No. 1, January 2009 40-41
