Eur J Cardiothorac Surg 2016;49:234–41.
This European multicentre experience, with the largest cohort ofpatients with Perceval S valves to date, shows excellent clinicaland haemodynamic results that remain stable even up to the 5-year follow-up.
Even in this elderly patient cohort with 40% octogenarians, bothearly and late mortality rates were very low.
There were no valve migrations, structural valve degeneration orvalve thrombosis in the follow-up.
The sutureless technique is a promising alternative to biologicalaortic valve replacement.

From April 2007 to August 2012, 731 consecutive patients (mean age: 78.5 years; 68.1% females; mean logistic EuroSCORE 10.9%) underwent AVR with the Perceval valve in 25 European centres.
Isolated AVR was performed in 498 (68.1%) patients.
A minimally invasive approach was performed in 189 (25.9%) cases.
The cumulative follow-up was 729 patients-years.

Hospital cost and savings
PURPOSE:To evaluate and compare the clinical outcomes and hospital costs of using sutureless aortic valves vs conventional stented aortic valves.METHODS:Between 2007 and 2011, 52 elderly patients undergoing aortic valve replacement for aortic stenosis in our center had a sutureless valve inserted. From among 180 patients who had a stented valve inserted during the same period, 52 patients were matched to the sutureless group, based on age, gender, and operation type. We compared clinical outcomes and hospital costs between the two groups.RESULTS:The sutureless group had a higher Euroscore (logistic Euroscore I) risk (12.8 vs 9.7; p = 0.02), with significantly shorter aortic cross-clamp (ACC) time (p < 0.01), cardiopulmonary bypass (CPB) time (p < 0.01), intensive care unit stay (p < 0.01), intubation time (p < 0.01), and overall hospital stay (p = 0.05). The sutureless group also revealed a significant hospital cost saving of approximately 8200€ (p = 0.01).CONCLUSIONS:The clinical and hemodynamic outcomes of using the sutureless bioprosthesis were excellent. The reduced ACC and CPB times had a favorable effect on the duration of intubation and intensive care stay, resulting not only in faster recovery and discharge home, but also in a significant hospital cost reduction.

Evangelismos Hospital Experiencewith sutureless & rapid deployment AVRs
192 AVRs with Perceval S sutureless (2013-2019)
(30 S, 75 M, 56 L, 31 XL Total: 192)
12 AVRs with Intuity - Edwards
164 scheduled procedures : 24 with CABG, 3 on REDO AVR, 2 with concomitant MVR
14 Postop Pacemaker implantations (7.2%)
In 4 cases the valve had to be repositioned.
6 non valve related in hospital deaths (3.1%)
1 acute MI 4 months postop without clinical effect and clean angiography.
1 late endocarditis following hip replacement (died without surgery)

The new generation rapid deployment and sutureless valves provide superior hemodynamics over the previous generation stented bioprosthesis. They are also very compatible with minimally invasive technics.
They compete successfully TAVIs with similar hemodynamics, less stroke rate and almost no paravalvular leak.
They are also the treatment of choice in cases with porcelain aorta or small aortic anulus.
The collective data tend to prove these valves as the first treatment choice for every patient requiring valve replacement with bioprosthesis.
