THE IMPACT OF TRANSCATHETER AORTIC VALVE IMPLANTATION IN PATIENTS WITH AORTIC STENOSIS
Aortic stenosis (AS) is the most common valvopathy in elderly patients, with an increasing prevalence due to aging process of population, current guidelines recommending transcatheter aortic valve implantation (TAVI) as a choice of intervention. Frailty is an important predictor of outcomes in AS patients who undergo TAVI, but there is no consensus in its preoperative evaluation. Aim: to compare the clinical outcomes of TAVI with conventionally surgically treated patients. Material and methods: The data of all aortic valve procedures performed in over 65 years patients, treated at Cardiovascular Institute from Iasi (January 2015-September 2019) were analyzed. The propensity score was used to compare the prognostic of patients. Results: The target group included 70 patients referred to TAVI compared to a second group of 98 patients who undergone surgical aortic valve replacement (SAVR). The mean age of TAVI patients was higher than SAVR group (76.47 vs. 64.37). The heart failure associated with the valvular pathology was more severe in the TAVI group (61.43% patients included NYHA class III and 35.71% patients NYHA class IV) compared to the SAVR group (58.16% patients were NYHA class III and 7.14% patients were NYHA class IV). Atrial fibrillation was the most frequent arrhythmia found in both groups (13.57% TAVI and 41.11% SAVR). Conclusions: The present study highlights the place of TAVI in current treatment of high surgically risk patients with SA.
