Svensson's (Modified Bentall) Technique using a Long Interposed Graft for Left Coronary Artery Reconstruction
Backgrounds: Aortic root replacement remains challenging in coronary artery reconstructions.
Methods: From 1992, 40 patients (54.7±13.6 years; 4 with Marfan syndrome) underwent Svensson's technique, 11 of whom had histories of proximal aortic operations. The technique included coronary ostial reconstructions of the right with the buttons's technique and the left with a long interposed graft (8 or 10 mm) anastomosed anteriorly in the composite graft. The technical advantages are unnecessary dissection around the left coronary artery, minimal tension and easy visualization of all anastomoses. Indications were annulo-aortic ectasia (n = 26), acute/chronic aortic dissection (n = 6 and 2), infective endocarditis (n = 5) and aortic stenosis with porcelain aorta (n = 1).
