We found the recent article looking at the impact of transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (sAVR) on right ventricular (RV) function very interesting.1 The authors used speckle tracking echocardiography to assess the impact of TAVI on RV function in two separate groups—one which had undergone TAVI, and the other which had undergone sAVR. They concluded that RV function deteriorated significantly in those who had undergone sAVR while there was no reduction in RV function following TAVI.

These results are in keeping with those of one of our studies, which assessed the effects different cardiothoracic operations had on postoperative RV function. We also noted a similar reduction in RV long axis function in patients post-surgery when assessed by tissue Doppler …
