Project description:This report describes the case of a symptomatic patient with a right coronary artery fistula draining into the coronary sinus who underwent transcatheter closure, which was deployed in the drainage site to seal off the exit of the fistula. (Level of Difficulty: Advanced.).

Right Coronary Artery to Coronary Sinus Fistula Post Endomyocardial Biopsy: A Case Report of a Rare Complication.

Project description:Endomyocardial biopsy (EMB) continues to remain the gold standard for surveillance of rejection post orthotropic heart transplantation (OHT). It can be performed under fluoroscopic or echocardiographic guidance. In the hands of an experienced operator, the complications of EMB are uncommon with <1% chance of any serious acute complications. Most common complications of EMB include access site-related complications, namely, venous thrombosis, carotid cannulation, hematoma, air embolism, and pneumothorax. We present a case of a rare complication of EMB in a patient with OHT causing a coronary sinus to right coronary artery (RCA) fistula.

Giant Aneurysm of the Right Coronary Artery: Multimodality Imaging and Interventional Management.

Project description:A large (40-mm) circular structure in the right atrioventricular groove was detected by transthoracic echocardiography and was diagnosed as a giant aneurysm of the right coronary artery. Through invasive mapping by a guide extension catheter, the aneurysm could be excluded by implantation of 3 overlapping stent grafts. (Level of Difficulty: Beginner.).

Successful coil embolization of a large right coronary artery-coronary sinus fistula causing a significant left-to-right shunt: a case report.

Project description:BackgroundThis case reviews a challenging but successful transcatheter coil embolization of a large congenital coronary artery fistula (CAF) causing a significant left-to-right shunt.Case summaryA 51-year-old female with no significant prior history presented with symptoms of dyspnoea and chest discomfort. Extensive evaluation revealed a large CAF between a tortuous right coronary artery (RCA) and the coronary sinus (CS) composed of three aneurysmal pseudochambers. Closure of the RCA-CS fistula was attempted through coil deployment into the fistula neck. However, due to the brisk flow through the fistula, both coils embolized into the fistula sac. An alternative location was subsequently identified on three-dimensional rendering of a computed tomography angiography scan, which revealed a sharp bend in the RCA prior to the fistula neck and distal to the posterior descending artery (PDA) takeoff. Repeat attempt at embolization was accomplished using a telescoping system to reach and occlude the targeted bend. The coil mass remained stable and angiography demonstrated reduced flow through the fistula and preserved patency of the PDA. The decreased residual flow through the fistula secondary to the initial embolization attempt likely aided the successful deployment of coils in the second and final attempt. At 1 year, the patient was doing well with resolution of her symptoms and no clinical symptoms of coronary ischaemia.DiscussionWe suggest that an initial unsuccessful attempt at transcatheter embolization of a CAF should not preclude subsequent attempts for closure when there exists an appropriate indication.

A case report of a young woman with pulmonary emboli and a right coronary artery-to-coronary sinus fistula.

Project description:BackgroundCoronary artery fistulae are rare cardiovascular anomalies that can present with atypical symptomatology and therefore pose diagnostic challenges, especially in young patients.Case summaryA 34-year-old woman presented with left-sided pleuritic chest pain, haemoptysis, and flu-like symptoms. Initial evaluation revealed multiple left-sided pulmonary emboli, and her transthoracic echocardiography showed turbulent flow in a dilated coronary sinus. A right coronary artery (RCA) to coronary sinus fistula was confirmed by computed tomography coronary angiogram. The patient was treated with lifelong anticoagulation, and a subsequent stress cardiac magnetic resonance imaging did not show inducible myocardial ischaemia. As such, the patient was managed conservatively.DiscussionUtilization of multi-modality imaging is of utmost importance for diagnostic and therapeutic purposes in coronary artery fistulae. In this case report, our patient presented with unprovoked pulmonary emboli, which could be caused by the turbulent flow and stasis, due to the RCA-to-coronary sinus fistula.
