Left ventricular assist device explantation using a new double-patch technique†.

Objectives: There are several surgical approaches for explanting a left ventricular assist device (LVAD) after recovery of cardiac function. Thus, remaining ventricular assist device components may bear significant risks of infection or thrombosis. We hereby report our technique and two-center experience with explantation of LVADs using a new double-patch technique.

- This study aimed to assess the outcomes of patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR) using the 34 mm Evolut R valve.
- It was found that while this valve had a device success rate of 87.4%, it also led to a higher rate of permanent pacemaker implantation (22.4%) compared to other valve sizes.
- Overall, the 34 mm Evolut R performed similarly to other valve sizes in terms of device success, indicating its effectiveness despite the increased pacemaker requirement.
Background: Despite continuous improvements in transcatheter aortic valve implantation (TAVI), periprocedural strokes remain a devastating complication. Randomized controlled trials failed to demonstrate a reduction in clinically apparent strokes or mortality after TAVI due to cerebral embolic protection (CEP). To identify potential targets of CEP strategies during TAVI, we evaluated affected brain regions, and temporal patterns of stroke onset in a routine clinical sample.

Physiological range of aortic angle (AA) is unknown; hence there is no cutoff AA for classifying HA. Moreover, patient characteristics predicting HA are under-investigated.
View Article and Find Full Text PDFBackground: Bioprosthetic valve fracture (BVF) is a technique to reduce gradients in valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) procedures. The outcome of VIV-TAVI with BVF has not been compared with VIV-TAVI without BVF.
Aims: The aim of this study was to evaluate the outcome of VIV-TAVI with BVF compared to VIV-TAVI without BVF.
Aims: The relevance of spontaneous echo contrast (SEC) and left atrial appendage thrombus (LAAT) in patients undergoing transcatheter aortic valve implantation (TAVI) remains unclear. In this study, we aimed to assess the prevalence of SEC and LAAT and evaluate the impact on periprocedural outcome after TAVI.
Methods And Results: A total of 2,549 consecutive patients underwent TAVI between 2008 and 2017.
