A bstractIntroduction: After the promising early results with Port‐Access mitral valve (MV) surgery, the mid‐term results were evaluated. Methods : Among 31 patients receiving this surgery, there were two subgroups (A and B). The 14 patients in group A (7 men, 7 women, 64.0 ± 12.8 years, LVEF 0.62 ± 0.118) received the procedure exactly as proposed by Heartport. The 17 patients in group B (6 men, 11 women, 63.0 ± 11.48 years, LVEF 0.61 ± 0.117) received a modified technique for a low complex procedure. The underlying diseases were MV insufficiency (n = 14), MV stenosis (n = 9), and combined MV disease (n = 8). One female patient had a partial atrial ventricular canal. Results: Perioperative mortality was 3.2%. Survival at 39.0 ± 6.3 months (median ± SEM) was 93.5%. Two patients required intraoperative inotropic and mechanical support (intro‐aortic balloon pump [IABP]). One of these two patients died on postoperative day 3 due to low cardiac output syndrome. All ther patients survived the procedure. Twenty‐four patients underwent MV replacement, 7 patients recalved MV repair, and 1 patient received, in addition, ASD repair. In group B, operative time, ICU stay, and hospitalization was shorter. Conclusions: Good early results after Port‐Access MV surgery were confirmed by equal mid‐term results. The patients are satisfied with the surgical and the cosmetic results, however, Port‐Access MV surgery still has to prove superior outcome compared to conventional MV surgery. In selected cases a true reduction of the surgical trauma is possible.
