Baseline characteristics
A total of 152 consecutive intermediate-risk patients were included between 2012 and 2018: 104 patients belonged to the TAVR subgroup and 48 patients belonged to the RDAVR subgroup. Clinical FU at two-years was completed for the entire population. Mean age was 82.74±6.36 years and female gender was predominant (n=78, 51.32%). Mean body surface area (BSA) was 1.74±0.2 m² and mean Body Mass Index (BMI) was 25.41±4.45 kg/m2. Mean EUROSCORE II was 6.03 ±1.64%. Patients belonging to the RDAVR subgroup were significantly younger (79.54±5.95 years versus 82.60±6.02 years, p=0.01) and their EUROSCORE 2 was significantly higher (6.61±1.82 versus 5.63±1.54, p=0.005). One hundred and nineteen patients had hypertension (78.29%) and 35 patients (23.03%) had severe renal insufficiency. One hundred and nine patients (71.71%) were class 3 or 4 NYHA at inclusion. Table 1.
Mean left ventricular ejection fraction (LVEF) was 56.01±13.03%. All patients had a severe AS, with a mean indexed aortic valve area of ​​0.41±0.1cm²/m² and a mean trans-aortic gradient of 51.68mmHg±14.69mmHg. Eleven patients (7.24%) had a bicuspid aortic valve. Systolic pulmonary artery pressure (sPAP) was similar between both groups. The baseline echo parameters were comparable between both subgroups. Table 2.
