Abstract

Statement of the Problem: The aim of this retrospective study is to evaluate the safety and performance of the perceval suture-less valve in patients undergoing aortic valve replacement (AVR). We report the 30-day clinical, echocardiographic and hemodynamic outcomes of 139 patients.

Methodology & Theoretical Orientation: From January 2014 to December 2026, 139 patients underwent suture-less aortic valve replacement. Their operation notes, PACS records and per operative TOE findings were studied retrospectively. Patients with bicuspid aortic valve and abnormal STJ: annulus ratio was excluded.

Findings: 92 patients underwent isolated aortic valve replacement (group A) with perceval valve and 47 patients had combined procedures of AVR and coronary artery bypass grafting (group B). The patients received a size S (n=23), M (n=39), L (n=42) or XL (n=35) prosthesis. Perceval valve was successfully implanted in 135 patients (97.1%). Mean cross clamp and bypass time was 40 and 63 minutes for isolated cases, while it was 68 and 107 minutes for combined cases. Three patients (2.1%) died within 30 days. Four patients suffered stroke and five patients went into acute renal failure. Median ICU and hospital stay was 2 and 8.5 respectively. Four valves were explanted due to significant para-valvular leak after surgery. Five patients had permanent pacemaker as a result of complete heart block and mean post-operative drainage was 295 ml for isolated case and 457 ml for combined cases.

Conclusion & Significance: Early post-operative results showed that perceval valve is safe. It can be implanted with short cross clamp and bypass time. Further follow up is needed to evaluate the long-term outcome with this bio-prosthesis.
