摘要：
Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare but potentially fatal complication of infective endocarditis and aortic valve surgery. 149 patients with P-MAIVF, including 7 cases in our hospital and 142 cases from the literatures, were comprehensively analyzed. P-MAIVF is located in the mitral-aortic intervalvular fibrosa area, which communicates with the left ventricular outflow tract. The cavity of P-MAIVF expands during systole and collapses during diastole. Endocarditis and aortic valve surgery are the most frequent causes. Symptoms of endocarditis, chest pain, heart failure, dyspnea, cerebrovascular accidents and systemic embolism are important clinical presentations. The formation of a fistulous tract, coronary artery compression, and rupture into pericardium are important complications. Transesophageal echocardiography is superior to transthoracic echocardiography in identifying P-MAIVF. Surgery is the treatment of choice with P-MAIVF repair and aortic valve replacement.
