AbstractHypertrophic cardiomyopathy is a genetic myocardial disorder. In such patients, myocardial bridging is the most frequent encountered coronary arterial anomaly. Patients may, however, on occasion, present with other much rarer malformations of the coronary arteries. Duplication of the right coronary artery is a very rare anomaly. We have now encountered a patient with hypertrophic cardiomyopathy in whom we found myocardial bridging of the anterior interventricular coronary artery and duplication of the right coronary artery. To the best of our knowledge, this association has not previously been described.

AbstractWe describe a patient with pulmonary atresia and intact ventricular septum in whom the right atrium was divided by a vascular aneurysm located in the right atrioventricular groove. We postulate that the structure represents an aneursymally dilated right coronary artery taking anomalous origin from the pulmonary trunk, with fistulous communication to the right atrium. We discuss the findings relative to concepts of development of the coronary arteries in normal hearts and in pulmonary atresia with an intact ventricular septum.

Abstract Background and aims: The incidence of Coronary Artery Disease (CAD) has reached alanning proportions in India. The pathological hall mark of CAD is myocardial ischemia resulting from the atherosclerotic narrowing of coronary arteries. In this era of advanced interventions and cardiac surgery, a thorough knowledge of normal and variant anatomy of coronary arteries is of prime significance and of great use both to the clinicians and anatomists. Materials and methods: One hundred coronary angiograms of patients free of disease were studied in detail in different profiles. The data obtained was quantified according to their frequencies. The relation between the length of left main coronary artery and coronary artery dominance was statistically analyzed using the 'Chi Square test for Trend'. Results: This study highlighted some interesting findings such as the origin of Sino- atrial nodal artery from the second segment of right coronary artery in 3% of cases, double right marginal artery in 4% cases. Other variations such as Mouchet's posterior recurrent interventricular artery, origin of circumflex artery from the right coronary artery and abnormal communication between the terminal parts of right coronary artery and circumflex artery were each noticed in 1 % of cases. Conclusions: Coronary arteries and their branches are prone to variations in their course and morphology. Prior knowledge about this is important for the interpretation of coronary angiograms and surgical myocardial revascularization. The present work on normal and variant pattern of coronary arteries will help in gathering momentum to the already advancing research work in this field.

A 76-year-old woman underwent coronary angiography for chest pain. On the coronary angiogram, no significant coronary artery atherosclerotic stenosis was observed. Multiple coronary artery microfistulas, draining from the left anterior descending artery to the left ventricle and from the posterior descending artery of the right coronary artery to the left ventricle, were observed. Apical wall thickening and fistula flow from the left anterior descending artery were demonstrated by using transthoracic echocardiography. We describe a rare case of multiple coronary artery microfistulas from the left and right coronary artery to the left ventricle combined with apical hypertrophic cardiomyopathy.

We have correlated the location of early atheroma with vessel geometry in the major coronary arteries of subjects dying of noncardiovascular causes under 40 yr of age. We analyzed only those vessels affected minimally by very early (fatty) disease. In each of the three major branches, disease was concentrated close to the entrance and diminished with distance downstream. Circumferential distribution of disease was also not random. In the right coronary artery, lesions were concentrated on the inner wall of the major curvature. Immediately downstream of the entrances of both branches of the left coronary artery, the flow-dividing walls were spared. Further downstream in the left anterior, descending branch plaques followed a spiral distribution. We believe these patterns may be determined by local mechanical factors.

Ectopic origin of the right coronary artery from the left sinus of Valsalva is an extremely rare anomaly of coronary arterial morphology, often incidentally discovered and clinically silent. We, hereunder, experienced a case of ectopic origin of the right coronary artery from the left sinus of Valsalva.

Abstract Background: The Anomalous origin of the Right Coronary Artery (RCA) from the Left Coronary artery sinus(AORL) is one of the abnormal origins of the coronary arteries. Most of these issues seldom have effects on human health, but some individuals may have symptoms such as myocardial ischaemia or even sudden death. Recently, researchers are studying AORL through clinical cases, but study based on computational fluid dynamics (CFD) is rarely seen. In this study, haemodynamic changes between normal origin of the RCA and AORL are compared according to numerical simulation results.Methods: Realistic three-dimensional models of 16 normal right coronary arteries and 26 abnormal origins of the right coronary arteries were reconstructed, respectively. The blood flow was numerically simulated using software ANSYS. This study involves one-way fluid-solid coupling finite element model in which the blood is assumed to be incompressible Newtonian fluid, and the vessel is assumed to be isotropic, linear elastic material.Results: The differences of the cross-sectional area at the inlet between the normal group and the abnormal group was significant ( P <0.0001). There were significant differences in the volumetric flow ( P <0.0001) and the pressure ( P =0.0001). There were positive correlations with the ratio of the cross-sectional area of the RCA to the inlet area of the ascending aorta (AAO) and the ratio of the inlet volumetric flow of the RCA to the volumetric flow of the AAO, in both the normal ( P =0.0001, r=0.8198) and abnormal ( P =0.0199, r=0.4925) group.Conclusion: This study shows that the cross-sectional area of the inlet of AORL may cause ischaemia symptoms, and the results may contribute to the further understanding of the clinical symptoms of AORL based on the haemodynamics.

Anomalies of the coronary arteries -- especially their abnormal origin from the pulmonary artery (ARCAPA) trunk -- are among the least common. They’re also the most dangerous of congenital heart defects with an incidence of 0.002% in the general population [Williams 2006]. The diagnosis exceedingly is difficult because anatomical abnormalities of the coronary arteries are subtle. We present a case of an anomalous origin of the right coronary artery.

AbstractAortopulmonary window is a rare congenital heart lesion. It might be associated with other CHDs, as well as with anomalous origin of the coronary arteries. Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is the most commonly described coronary artery anomaly in association with aortopulmonary window. We are describing a premature neonate who was diagnosed to have aortopulmonary window and ARCAPA immediately after birth, and had a successful operation at the age of 4 months. This report highlights the importance of very careful assessment of the coronary arteries in patients with aortopulmonary window.
