Patients with end-stage kidney disease (ESRD) represent a high-risk population in terms of both development of and death by cardiovascular diseases. Outcome data of ESRD patients with severe aortic valve stenosis (AS) treated by transcatheter aortic valve implantation (AVI) are scarce. We aim to compare the outcome of ESRD patients undergoing transfemoral (TF) or transapical (TA) AVI.

: Laparoscopic cholecystectomy (LC) is the most commonly performed operation in general surgery in the Western World. Gallbladder surgery, although most of the time simple, always offers the possibility of unpleasant surprises. Despite progress, the incidence of common bile duct injury is 0.

- * The use of this approach significantly increased from 18.7% in 2019 to 97.8% by 2023, with a mean procedure time of 127 minutes and no intraoperative deaths reported.
- * Thirty-day adverse events included a 1.9% rate of major complications, with factors like intraoperative conversion and respiratory failure being linked to higher risks of complications and mortality.
: Minimally invasive cardiac surgery is often avoided in patients with obesity due to exposure and surgical access concerns. Nonetheless, these patients have elevated periprocedural risks. Minimally invasive transaxillary aortic valve surgery offers a sternum-sparing "nearly no visible scar" alternative to the traditional full sternotomy.

Design: Prospective observational study SETTING: Single-center study at a tertiary academic cardiac center PARTICIPANTS: Forty-nine patients undergoing minimally invasive surgical aortic valve replacement INTERVENTIONS: Acquisition of full-volume images of the left ventricle after induction of anesthesia and at the end of surgery using transesophageal echocardiography (TEE), and analysis of the datasets using 3D speckle-tracking-based myocardial deformation analysis (Tomtec Arena).
Measurements And Main Results: Of the 49 complete volume datasets, 30 (61%) had quality sufficient for speckle tracking.
