Coronary sinus injuries related to the use of retrograde cardioplegia are uncommon. In most cases injuries are encountered with overinflation of the coronary sinus catheter balloon or traumatic catheter insertion. This article describes three cases of coronary sinus injury during retrograde cardioplegia administration in patients with ventricular hypertrophy, while the heart was manually retracted to expose the posterior myocardium. We propose that the risk of coronary sinus injury during retrograde cardioplegia, in patients with left ventricular hypertrophy, can be minimized by avoiding excessive retraction of the heart, deflation of the retrograde catheter during retraction, and the use of a left ventricular vent.

Rationale: Quadricuspid aortic valve (QAV) is a rare condition with a very low incidence. Anomalous aortic origin of a coronary artery (AAOCA) is the most prevalent form of coronary anomaly. One variant of AAOCA is the anomalous aortic origin of the left coronary artery from the right coronary sinus (L-AAOCA).

Background: The role of a prothrombotic state in atrial fibrillation (AF) progression to permanent arrythmia (PerAF) is unclear. Formation of denser and poorly lysable fibrin clots has been observed in AF patients also with sinus rhythm in association with higher stroke risk. We investigated whether altered fibrin clot properties and other prothrombotic state markers may contribute to AF transition to PerAF.

Coronary sinus (CS) defects are rare congenital cardiac anomalies that occur in isolation or with other congenital heart diseases. Persistent left superior vena cava (LSVC) is a relatively common entity that usually drains into the CS, is of no hemodynamic consequence, and is easily diagnosed on echocardiography by a dilated CS and an antegrade flow toward the heart. However, a combination of LSVC and CS defect may reverse its flow direction and CS dilation may be absent.

A young female patient suffered cardiogenic shock after undergoing surgery for an ectopic pregnancy. Coronary artery computed tomography angiography (CTA) revealed a left main artery (LM) originating from the right coronary sinus and traveling between the aorta and pulmonary artery. We successfully resuscitated the patient with mechanical circulatory support using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and an intra-aortic balloon pump (IABP).
