AbstractWe report an extremely rare case of a 14-month-old girl who was diagnosed with a single right coronary artery with coronary artery fistula communicating with the right ventricle and congenital absence of left coronary artery. Angiography showed a dilated and tortuous single right coronary artery draining into the right ventricle, absence of left coronary system, and left ventricular coronary circulation supplied via collateral vessels.

Giant Size

<p>Coronary artery fistula (CAF) is a rare entity. Sometimes it may associate with mild diffuse or segmental coronary ectasia. CAF with giant coronary artery is exceptionally rare. We present a unique case of a 49-year-old female patient with a giant right coronary artery of diffuse ectasia coexisting with a fistula draining into the right ventricle. To our best knowledge, CAF with diffuse coronary ectasia of such giant size has never been reported. The patient was treated successfully by resection of the dilated right coronary artery, fistula closure, and coronary artery bypass grafting.</p>

The frequency of coronary artery fistula among all coronary angiography patients is 0.1% to 0.2%; however, involvement of both the pulmonary artery and the right ventricle is a rare clinical entity. A 53-year-old man patient was admitted to our clinic with rarely occurring chest pain, palpitations, and dyspnea. A coronary angiogram showed a fistula between the left main coronary artery and both the pulmonary artery and the right ventricle. We performed a ligation of this fistula without cardiopulmonary bypass. Aorta and right ventricle sutures were made, and the proximal and distal portions of the fistula were obliterated with 5-0 Prolene sutures and previously prepared Teflon felt. The patient recovered and was discharged without any complications. The surgical indications for coronary artery fistulas are symptomatic disease, an aneurysmic coronary artery, signs of heart failure, and ischemia. The surgical options in such cases�depending on whether the fistula is complicated or not�are simple ligation or transarterial ligation under cardiopulmonary bypass.

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.

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.
