A Case of Quadricuspid Aortic Valve With Coronary-Pulmonary Artery Fistula

抄録

A 68-year-old man was admitted to our hospital with dyspnea and palpitation on slight exertion. Echocardiography revealed a quadricuspid aortic valve with severe aortic regurgitation and turbulent blood flow in the left lateral aspect of the main pulmonary artery just above the pulmonic valve. Coronary angiography depicted a coronary artery fistula arising from the left anterior descending artery and draining into the main pulmonary artery. An aortic valve replacement with a prosthesis and closure of the fistula were performed. This is a rare case of quadricuspid aortic valve combined with coronary- pulmonary artery fistula.
