This study compares the influence of two different annuloplasty attachment suture applications, namely use an automated fastener versus manually tied knots using a traditional knot pusher, on total operation time, cardiopulmonary-bypass time and cross-clamp short-term outcome. Sixty patients underwent isolated minimally invasive mitral valve repair in Carpentier Type-II disease with implantation ring combination correction prolapsing leaflet artificial chords. The first 30 after implementation novel were compared last corrected pusher. No significant differences regard to demographic data (age, gender, NYHA class, ejection fraction, BMI, cardiovascular risk factors) between groups found. All received run. Bretschneider HTK was used for cardioplegic cardiac arrest all patients. Transesophageal transthoracic echocardiography at end discharge revealed no (n = 25), trace 28) or mild 7) residual regurgitation evidence dehiscence without any clinical groups. Cross-clamp, total- significantly reduced group pusher (87.1 ± 17.9 vs. 101.3 17.8; p < 0.01, 138.1 25.6 152.7 24.9; 0.05, 203.9 31.02 223.8 29.01; respectively). Our results indicate safe, reliable fast application device savings cardiopulmonary bypass.
