Abnormal Origin of Right Coronary Artery From Left Ventricle With Bicuspid Aortic Stenosis

Objective This study was performed to identify the effects of different surgical approaches on the right coronary artery ostium in patients with congenital supravalvular aortic stenosis (SVAS) and to determine how to avoid surgically induced right coronary artery occlusion. Methods The surgical techniques and outcomes of 91 patients who underwent surgical treatment of SVAS from 2008 to 2015 in our institution were retrospectively reviewed to identify the causes of early death, reoperation, and extracorporeal membrane oxygenation (ECMO) support. Results Four perioperative deaths (Doty’s technique, n = 4), six cases of ECMO support (Doty’s technique, n = 4; Brom’s technique, n = 1; McGoon’s technique, n = 1), and eight reoperations (Doty’s technique, n = 5; Brom’s technique, n = 2; McGoon’s technique, n = 1) occurred. In cases of reoperation, adjustment of the shape and position of the right coronary sinus patch relieved the malignant arrhythmia. Conclusion Different surgical techniques have different effects on the right coronary artery. The shape of the patch inserted into the right coronary sinus should be carefully clipped to avoid distortion and ischemia of the right coronary artery.

The Impact

Abstract Introduction Total occlusion of the left main coronary artery is a very rare finding in coronary angiography because of its highly lethal nature. Right coronary artery dominance and extensive collateral circulation are the principal determinant factors of survival after total occlusion of the left main coronary artery. The impact on the left ventricle is often significant with a profound alteration of its systolic function. Case presentation We describe a 52-year-old North African man, a tobacco smoker, who presented symptoms of unstable angina related to a total chronic occlusion of his left main coronary artery with a right coronary artery stenosis. Unexpectedly, the impact on his left ventricle was absent with normal dimensions and systolic function. He underwent a successful on-pump coronary artery bypass grafting with uneventful postoperative course and good recovery. Conclusions Total occlusion of the left main coronary artery is a rare condition, the fact that the left ventricle retains a normal size and systolic function makes it exceptional, which must be kept in mind to avoid dangerous examinations and delayed treatment. Coronary artery bypass surgery should be considered the main treatment of total chronic occlusion of the left main coronary artery.

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.
