Resumen:
Background. Surgical treatment of active prosthetic aortic valve endocarditis presents a challenge for cardiac surgeons because of tissue friability and destruction caused by infection. Sutureless prostheses, such as the Perceval S (LivaNova, Saluggia, Italy), have emerged as an option among the different surgical approaches for these complicated cases.
Methods. This study presents data from 9 patients who underwent aortic valve re-replacement with the Perceval S because of active prosthetic aortic valve endocarditis between January 2014 and August 2016. Hemodynamic performance (mean transprosthetic gradient and type of aortic regurgitation) was assessed intraoperatively after weaning from cardiopulmonary bypass, at discharge, and to 6 months postoperatively.
Results. After weaning from cardiopulmonary bypass, cases 1 and 3 through 6 had no or trivial aortic regurgitation, cases 7 and 8 presented with trivial to mild regurgitation, case 9 showed mild intraprosthetic regurgitation, and case 2 had mild periprosthetic regurgitation. Cases 4 and 7 died of septic shock and multiorgan failure in the perioperative period. In the remaining patients, severity of aortic regurgitation maintained practically invariable at discharge compared with intraoperative results. These 7 patients did well at 6-month follow-up, with good clinical and hemodynamic performance of the Perceval S prosthesis. The median of mean transprosthetic gradient was 11 mm Hg (interquartile range: 10 to 12 mm Hg). Only patient 2 showed mild periprosthetic regurgitation; patient 9 showed mild intraprosthetic insufficiency, and the remaining patients had no or trivial regurgitation.
Conclusions. The sutureless Perceval S valve is a reasonable alternative for surgical treatment of prosthetic aortic valve endocarditis. (C) 2018 by The Society of Thoracic Surgeons
