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.

A patient was born with truncus arteriosus type 2, left aortic arch, anomalous origin of arch vessels, left coronary artery from the right common carotid artery, and multiple extracardiac anomalies. Surgery involving translocation of the left coronary artery to the truncal root, division of branch pulmonary arteries from the truncal artery, and right ventricle-to-branch pulmonary arteries conduit placement was performed at the age of four months. Closure of the ventricular septal defect using a one-way fenestrated patch and conduit upsizing was performed successfully when the patient reached four years of age.

Single Right Coronary Artery

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.

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.

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.
