Mortality WITHOUT preoperative PVO Sutureless: 1.8% (1/57) Conventional: 8.6% (6/70) p=0.199 WITH preoperative PVO Sutureless: 12.5% (3/24) Conventional: 46.4% (13/28) P<0.01
Postoperative PVO WITHOUT preoperative PVO Sutureless: 1.8% (1/57) Conventional: 10% (7/70) P=0.07 WITH preoperative PVO Sutureless: 4.2% (1/24) Conventional: 25% (7/28) p=0.06
Free from death and PPVO (without Preoperative PVO)
Free from death and PPVO (with Preoperative PVO)
Sutureless technique A better option
Key points Fully relieve preoperative PVO Atriopericardial anastomosis “no touch” suturing technique
Thank you
