Perceval Less Invasive Aortic Replacement Register: multicentric Spanish experience with the Perceval S bioprosthesis...

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Devices

Background:

• Aortic valve replacement (AVR) risk is decreasing due to new techniques.
• Sutureless prostheses offer an alternative for specific patient groups.

Purpose of the Study:

• To evaluate the outcomes of sutureless aortic valve implantation in moderate-to-high-risk patients.
• To present results from a Spanish multicenter registry.

Main Methods:

• Prospective multicenter study from November 2013 to November 2016.
• Data collected from 448 patients receiving the Perceval S prosthesis.
• Analysis of perioperative and follow-up outcomes.

Main Results:

• Mean patient age was 79.2 years; 61.2% were female, with a mean EuroSCORE I of 11.15%.
• Observed mortality was 4.4%. Neurological events occurred in 2%.
• Survival at 6 months and 1 year was 98% for octogenarians; low rates of leakage and pacemaker implantation were observed.

Conclusions:

• Sutureless valve implantation is a reproducible procedure for moderate-to-high-risk patients.
• The technique demonstrates low morbidity and mortality.
• Good hemodynamic results and favorable long-term outcomes were achieved.
