Sutureless aortic valves in isolated and combined procedures: 13 years of experience in 784 patients
Abstract
Objective
The aim of this study was to evaluate the outcome and experience of the Perceval sutureless valve at our institution (UZ Leuven).
Methods
Between 2007 and 2019, 784 patients underwent sutureless aortic valve replacement using the Perceval valve (isolated or combined with other procedures). We performed a retrospective analysis of the postoperative and follow-up data.
Results
Mean age was 78 years with a median EuroSCORE II of 4.2% (interquartile range 2.6-7.2%). Isolated aortic valve replacement accounted for 45% of cases, 30% of cases was aortic valve replacement in combination with coronary artery bypass grafting and the remaining 25% were other combined procedures. The median cross-clamp times were 38 min in single AVR, 70min in cases with CABG and 89 min in multiple valve cases. Device success was 99.1% and in-hospital mortality was 3.3%. Postoperative stroke or transient ischemic attack occurred in 1.9% of patients and 1% of patients had a new need for dialysis after surgery and p Median survival time was 7.0 years with a cumulative follow-up of 2797.8 patient-years. The 1-, 5- and 10-year freedom from reintervention were 99%, 97% and 94% respectively.
Conclusion
These data represent the longest follow-up available for the Perceval sutureless valve. We observed favorable early outcomes, low rates of early mortality, stroke and other major complications. Valve durability is promising with low rates of valve degeneration and a limited need for reintervention.
