A bstract Right thoracotomy is an alternative to mid‐sternotomy for left atrium access. The Port‐Access approach is an option that reduces the skin incision and obviates rib spreading. Patients and methods: From February 1997 until November 1999, 121 patients underwent mitral valve surgery through a right antero‐lateral thoracotomy using the Heartport cardiopulmonary bypass (CPB) system. Mean age was 60 years (31–84). Most patients had normal ejection fractions and were in NYHA Class II or III. Seventy‐five patients had valve repair (62%) and 46 (38%) had valve replacement. Pathologies were myxoid (n = 80), rheumatic (n = 30), chronic endocarditis (n = 5), annular dilatation (n = 3), sclerotic (n = 1), ingrowing myxoma (n = 1), and one closure of a paravalvular leak. Results. Two patients had conversion to sternotomy for aortic dissection (one died) with the Endo‐Aortic Clamp, and two others for peripheral vascular problems. One patient died at postoperative day 1 after reoperation for failed repair, another with double valve surgery on postoperative day 4 after two revisions for bleeding. Twelve underwent revision for bleeding (10%). Three had prolonged ICU stay for respiratory insufficiency. Two late valve replacements for endocarditis occurred. Echographic control revealed residual insufficiencies (grade 1–2) in two valvular repairs. There were neither paravalvular leaks nor myocardial infarcts. There were no cerebrovascular accidents due to embolic phenomena. Mean ICU and hospital stay were 2.1 and 8.7 days, with a major difference between the first 30 patients and those who followed. Conclusion: Port‐Access mitral valve surgery can be a valid alternative to conventional sternotomy and seems to be an important improvement in minimally invasive cardiac surgery.
