Abstract Cardiac paragangliomas are extremely rare. Sometimes surgical resection is a challenge owing to the proximity of vital structures and coronary arteries involvement. We report a case of a 34-year-old man with cardiac paragangliomas located between right atrium and right ventricle with a feeding blood supply from collaterals of the right coronary artery. In this case, we implanted a covered single stent (PK Papyrus®) in the right coronary artery with the objective of embolizing collateral branches and to reinforce the coronary artery wall. Although tumour mass was not reduced, vascularization was minimized, and this hybrid strategy made the surgery easier and safer.

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 Our study was performed on a total of 24 angioCT’s by each coronary artery executed on a GE LightSpeed VCT64 Slice CT Scanner. To assess the type of vascularization (coronary dominance) we used also dissection on fresh and formalin preserved hearts, injection of contrast substance followed by radiography and plastic mass injection followed by corrosion. Left coronary artery from origin I found a diameter of between 4.1 to 5.8 mm, the length of the left main coronary artery until its branching (bi or trifurcation) ranging from 3 to 11.8 mm. The diameter of the anterior interventricular artery, was between 1.8 to 3.4 mm, and when the anterior interventricular artery branched off a left marginal artery, it was less voluminous than the case when the marginal artery origin by trifurcation of coronary artery, with 1.8-2.5 mm. Anterior interventricular artery detach left anterior ventricular branches with a diameter of 1.2-2.2 mm. Circumflex artery present a diameter of 2.1 to 4.2 mm at the left aspect of the heart circumflex artery has a diameter of 2.1 to 3.4 mm. On the posterior surface of left ventricle from circumflex artery branches come off with 1.2 to 2.4 mm in diameter. Left marginal artery, when originate from the left coronary artery had a diameter of 2.1 to 2.8 mm. The right coronary artery presents at origin a diameter of 3.1 to 5.4 mm, from the coronary right for the anterior aspect of the right ventricle unhooking the branches with a diameter of 2.2 to 4.2 mm. To the posterior of the right ventricle right coronary artery gave branches with a diameter of 1.6 to 2.6 mm. Right marginal artery had a diameter of 1.6-2.2 mm, and in one case (4.17% from cases) had a diameter of 3.4 mm (when the right coronary origin was 5.4 mm ). From right the coronary atrial branches detaches with a caliber of 0.6-2 mm. Regarding the coronary dominance, we found on a number of 88 hearts that in 29.54% of cases there is predominance of right coronary artery in 25% of cases there is a predominance of the left coronary artery, and in 45.46% of cases there is a balance between the territories of the vascularity of the two coronary arteries.

AbstractAnomalous origin of the coronary arteries is a well-known phenomenon, but is less well reported in world literature. We present our findings in a one year old boy in whom there was bifid, or “y”, origin of the right coronary artery, co-existing with a fistula from the right coronary artery which opened into the right ventricle.

Abstract OnBehalf Cornwall A term neonate with poor condition at birth was noted to be markedly bradycardic when crying. ECG showed first degree heart block. Echocardiogram demonstrated poor bi-ventricular function. He was treated for Hypoxic ischemic encephalopathy (HIE). In the next few hours he developed short episodes of ventricular tachycardia with left bundle branch block and non-conducted P waves suggesting an origin of tachycardia from the right ventricle. His repeat ECHO suggested that he had right ventricular infarction due to a very rare finding of intermittent occlusion of the origin of the right coronary artery by an echogenic mass. He was transferred for emergency cardiac surgery to remove a clot of 1.6cm, occluding the right coronary artery. Histology findings were in keeping with a thrombus. Thrombophilia screen for both parents and infant were negative. MRI Brain did not show evidence of HIE suggesting his poor condition at birth was secondary to intermittent coronary ischemia. Discussion: Myocardial infarction (MI) in neonates is a rarely encountered and potentially life-threatening condition, with mortality rate as high as 90%. We present one of the first reported cases of successful surgical management of an acute right coronary artery thrombosis after an early diagnosis. The cause of thrombosis remains unclear in our patient. They were born in poor condition with initial pH 6.9 and lactate of 10, but with a structurally normal heart and negative thrombophilia screen. Perinatal asphyxia is a potential cause; however there is doubt that this may be a symptom rather than cause of the right coronary artery occlusion. Early diagnosis was key in management after a high level of clinical suspicion. He made significant recovery with near normal RV function, and is currently on captopril and carvedilol post-surgery. This is one of the first cases to document near full return of cardiac function following ischaemia to the right ventricle Abstract 478 Figure. 5

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.

SummaryFive previously reported cases have established the combination of a small right ventricle (sometimes with Uhl's anomaly), imperforate tricuspid valve with fibrotic tensor apparatus, congenital absence of the pulmonary valve, and an intact interventricular septum with muscular subaortic stenosis as a rare variant of tricuspid atresia. In this study of three new autopsy cases, we additionally identified Ebstein's malformation of the imperforate tricuspid valve, partial Uhl's anomaly, regional dysplasia of right ventricular myocardium and thinning of the interventricular septum by intramyocardial sinusoids from the right ventricle. All three new cases had epicardial anomalies of the right coronary artery—a fistula to right ventricle, ostial stenosis and proximal arterial hypoplasia. Sinusoidal connections from the right ventricle to the right coronary artery and to the sclerotic left anterior descending artery were identified in serial sections of the right ventricle and septum. Myofiber disarray, with thick walled intramyocardial arteries and sinusoids from left ventricle, involved the bulging subaortic interventricular septum. These studies are consistent with the hypothesis that defective development of the the right ventricle, along with its blood supply and associated atrioventricular and arterial valves, may underlie this unusual form of congenital heart disease.
