Prenatal diagnosis of a huge coronary artery fistula between the left coronary artery and the right ventricle was made by Doppler echocardiography at 22 weeks of gestation. Progression of the dilated fistula was monitored throughout pregnancy. The size of the fistula increased enormously up to 11 mm. Death occurred at birth. Monitoring of these fetuses is essential as severe complications can occur during pregnancy or at birth.

AbstractA single coronary artery is an exceedingly rare anomaly. Hereby, we present an unusual case of a young patient with an acute coronary syndrome who was found to have a single coronary artery originating from a single ostium in the right sinus of Valsalva with dual left anterior descending (LAD) arteries arising from the right coronary artery with two different anatomical courses, and additionally one of those LADs running a malignant intra-arterial course.

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

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.
