BACKGROUND: In elderly high-risk surgical patients, sutureless aortic valve
replacement (AVR) should be an alternative to standard AVR. The potential
advantages of sutureless aortic prostheses include reducing cross-clamping and
cardiopulmonary bypass (CPB) time and facilitating minimally invasive surgery and
complex cardiac interventions, while maintaining satisfactory hemodynamic
outcomes and low rates of paravalvular leakage. The current study reports our
single-center experience regarding the early outcomes of sutureless aortic valve
implantation. METHODS: Between October 2012 and June 2015, 65 patients scheduled
for surgical valve replacement with symptomatic aortic valve disease and New York
Heart Association function of class II or higher were included to this study.
Perceval S (Sorin Biomedica Cardio Srl, Sallugia, Italy) and Edwards Intuity
(Edwards Lifesciences, Irvine, CA, USA) valves were used. RESULTS: The mean age
of the patients was 71.15±8.60 years. Forty-four patients (67.7%) were female.
The average preoperative left ventricular ejection fraction was 56.9±9.93. The
CPB time was 96.51±41.27 minutes and the cross-clamping time was 60.85±27.08
minutes. The intubation time was 8.95±4.19 hours, and the intensive care unit and
hospital stays were 2.89±1.42 days and 7.86±1.42 days, respectively. The mean
quantity of drainage from chest tubes was 407.69±149.28 mL. The hospital
mortality rate was 3.1%. A total of five patients (7.69%) died during follow-up.
The mean follow-up time was 687.24±24.76 days. The one-year survival rate was
over 90%. CONCLUSION: In the last few years, several models of valvular
sutureless bioprostheses have been developed. The present study evaluating the
single-center early outcomes of sutureless aortic valve implantation presents the
results of an innovative surgical technique, finding that it resulted in
appropriate hemodynamic conditions with acceptable ischemic time.
