Journal of Cardiothoracic Surgery 2011 6 60 http content 6 1 60 JCTS JOURNAL OF CARDIOTHORACIC SURGERY CASE REPORT Open Access Non infective severe aortic paravalvular leakage 7 years after surgery the role of suture technique Marco Agrifoglio Sara Filippini Maurizio Roberto Marco Zanobini Luisa Gregorini and Francesco Alamanni Abstract We report a case of redo aortic prosthesis replacement for a severe paravalvular leak PVL in a man operated with continuous suture technique 7 years earlier. The severe aortic regurgitation was due to the rupture of the suture. In spite of operations to replace malfunctioning heart valves are common procedures and performed all over the world from more than 50 years there is still an open debate about the most suitable suture technique. In this case report we ll discuss if the suture technique has a role in preventing or leading complications as severe PVL. Keywords aortic valve replacement paravalvular leakage suture technique Introduction Paravalvular leak PVL after valve replacement is a rare but serious complication. Most frequently PVL is caused by a prosthetic valve endocarditis but it may also occurs without definite signs of infection. We report a case of redo aortic prosthesis replacement after 7 years from the operation and we discuss the role of suture technique in this case of severe paraprosthetic leak without any clearly infection signs. Case Report A 48-year-old man came to our hospital for sudden effort dyspnea. The patient underwent seven years ago to aortic valve replacement AVR with 25 mm On-X On-X Life Technology Inc. Austin TX USA mechanical prosthesis for severe aortic valve regurgitation and ascending aorta replacement with a tube graft n 28 for ascending aorta aneurysm. The AVR was performed using three semicontinuous 2-0 Prolene Ethicon Somerville NJ USA suture technique. The surgeon used three similar sutures with knots tied among them hence the term .
