[Left ventricular-right atrial communication resulting from infective endocarditis].
We report a rare case of acquired left ventricular-right atrial communication resulting from infective endocarditis. A 57-year-old male with aortic regurgitation due to infective endocarditis was referred to our hospital because of severe congestive heart failure. Preoperative transthoracic echocardiography showed aortic, mitral and tricuspid severe regurgitations. Intraoperative transesophageal echocardiography revealed left ventricular-right atrial shunt. The fistula was located at the atrioventricular membranous septum. The communication site from the left view was below the commissure between the right coronary cusp and non-coronary cusp, and from the right view was just above the tricuspid annulus of the septal leaflet. The fistula was closed directly with mattress suture and aortic valve replacement and both mitral and tricuspid ring annuloplasty were carried out simultaneously. The postoperative course was uneventful. It is important to inspect shunts carefully in echocardiography of infective endocarditis with massive regurgitations.
