Abstract/OtherAbstract:
OBJECTIVES: To evaluate longitudinal left and right ventricular function (LVF and RVF) after transcatheter aortic valve implantation (TAVI) as compared to surgical aortic valve replacement (SAVR) and LVF and RVF after TAVI by the transfemoral (TF) or transapical (TA) approach. BACKGROUND: Knowledge about differences in recovery of LVF and RVF after TAVI and SAVR is scarce. METHODS: Sixty patients (age 81±7 years, logistic EuroSCORE 16±10% ), undergoing TAVI (TF: n=35 and TA: n=25), were examined by echocardiography including atrioventricular plane displacement (AVPD) and peak systolic velocities (PSV) by tissue Doppler at basal RV free wall, LV lateral wall and septum preprocedurally, 7 weeks and 6 months postprocedurally. Twenty-seven SAVR-patients were matched to 27 TAVI-patients by age, gender and LVF. RESULTS: Early post- intervention, TAVI-patients had improved longitudinal LVF. However, when analyzed separately only TF, but not TA-patients, had improved LV lateral and septal AVPD and PSV (all p≤0.01). All TAVI patients, as well as the TF- and TA-group had unchanged longitudinal LVF between the early and late follow ups (all p>0.05). The SAVR-group had higher septal LVF than the matched TAVI-group preprocedurally, while postoperatively this difference was diminished. Longitudinal RVF was better in the TF-group than in the TA-group pre- and postprocedurally. Although the SAVR-group had superior longitudinal RVF preoperatively, this was inferior to TAVI postoperatively. CONCLUSIONS: Postprocedural longitudinal LVF and RVF in patients undergoing TF-TAVI, TA-TAVI or SAVR differ considerably. Preservation of longitudinal RVF after TAVI might influence the selection of aortic valve intervention in the future. (249 words) © 2013 Wiley-Liss, Inc.
