A hitherto unreported combination of pulmonary stenosis, single coronary artery anomaly, and coronary sinus to left atrial communication.

Background: We report a hitherto unreported combination of pulmonary stenosis, single coronary artery anomaly and coronary sinus to left atrial communication. Our case highlights the important value of coronary computed tomographic angiography and transthoracic echocardiography for the diagnosis of such anomalies and guidance for proper management.

Methods And Results: A 64-year-old male presented chest tightness and shortness of breath for 2 days.

Mitral valve blood cyst occlusion of the aortic valve leading to syncope: detection by transthoracic and contrast echocardiography.

Blood cysts of the mitral valve are rare in adults. These blood cysts are often asymptomatic. Blood cysts resulting in severe left ventricular outflow tract obstruction leading to syncope have not been previously report.
