Background: The effect of utilizing transapical approach for transcatheter aortic valve implantation (TAVR) on cardiac function has not been well studied.
Aims: The aim of this study is to determine the effect of using transapical approach for TAVR on cardiac function parameters.
Methods: 138 and 206 patients, who underwent TAVR in 2008-2015 using transapical and transfemoral approaches, respectively were studied. The clinical characteristics and the pre- and 1 month post-TAVR echocardiographic features of both groups were compared.
Results: Clinical characteristics were similar in the two groups except for higher Society of Thoracic Surgery estimated mortality score and less prevalence of chronic obstructive lung disease in the transapical group (Table 1a). The prevalence of diastolic dysfunction and the baseline diastolic parameters were similar (Table 1b). No significant changes were seen in the diastolic parameters after TAVR using both approaches (Table 1c). Less increment in stroke volume index and larger left ventricular end-diastolic dimension were seen after transapical vs transfemoral approach (-3.5 cc/m2 [-6.89- −0.15]; p=0.04 & 2.52 mm [0.4-4.6]; p=0.02).
Conclusions: Transfemoral TAVR was associated with more improvement in stroke volume index and geometry after 1 month compared to transapical approach. No significant differences in diastolic parameters were seen between the two approaches.
