Between April 2018 to December 2021, 30 elective patients underwent AVR with the Perceval Sutureless Valve. Inclusion criteria were critical aortic valve stenosis, age > 60 years and patient opting for sutureless valve. The informed consent was in all patients. Exclusion criteria includes patient not opting for sutureless valve, ratio between Sino tubular junction to annulus > 1.3, bicuspid aortic valve, dilated ascending aorta and annulus < 18mm. Patients demographic profile and pre-operative echocardiography findings are mentioned in Table 1 and 2.
Out of 30 patients, 19 were isolated AVR and 11 patients underwent combined AVR + Coronary Artery Bypass Grafting (CABG) with average number of grafts were 2.1 ± 0.8. (Table 3)
The study was approved by the ethics committee of our hospital. Post operatively, all patients were prescribed oral anticoagulation drug for three months to maintain INR up to 2.0, later on it was replaced with either single or dual antiplatelet drugs depending upon CABG or no CABG.
