Article Abstract
Patients with mechanical aortic valves are generally contraindicated for left ventricular assist device (LVAD) insertion because the prosthetic valve often becomes fixed in closed position. A 41-year-old woman with mechanical aortic valve prosthesis experienced sudden chest pain and developed cardiogenic shock. A paracorporeal pulsatile LVAD and a monopivot centrifugal pump as a right VAD (RVAD) were implanted. The mechanical aortic valve was intentionally left in place. Soon after the operation, LVAD support was discontinued daily for few seconds to allow the mechanical aortic valve to open and to avoid thrombus formation. The patient was successfully weaned off RVAD and received anticoagulation therapy with warfarin. On postoperative day 141, she was transferred to a university hospital where a HeartMate II LVAD was implanted, and the aortic valve was successfully replaced with a bioprosthetic valve. The patient is currently awaiting heart transplantation.

Aims: Non-pharmacological therapies for acute decompensated heart failure (HF) and cardiogenic shock have evolved considerably in recent decades. Short-term mechanical circulatory support (MCS) devices can be used as circulatory backup. While nearly all available devices use continuous flow, evidence indicates that pulsatile flow can be more effective.

Objective: Valve selection in acute type A aortic dissection (ATAAD) requiring aortic root replacement is challenging given the clinical acuity, unknown patient preferences, risk of surgical bleeding, and limited life expectancy. We sought to identify long-term outcomes of mechanical versus bioprosthetic aortic root replacement in young patients with ATAAD.
Methods: Retrospective review of our institution's database of ATAAD was conducted to identify patients aged 65 years and younger who underwent mechanical Bentall (mech-Bentall) or bioprosthetic Bentall (bio-Bentall) for ATAAD from 2002 to 2022.

BackgroundA stable guiding system is essential for successful carotid artery stenting (CAS), particularly when navigating tortuous aortic or supra-aortic anatomy. However, data on the mechanical behavior of stent delivery systems remain scarce.ObjectiveTo assess and compare the bending stiffness and trackability of five commercially available carotid stent delivery systems using bench-top experiments.

BackgroundThe optimal cerebral protection strategy during complex aortic surgery remains controversial, and various brain monitoring modalities are used to provide different information to improve cerebral protection. This study aims to compare the effect of the change in cerebral oxygen saturation during hypothermic circulatory arrest on the early postoperative neurological outcome in antegrade cerebral perfusion (ACP) versus retrograde cerebral perfusion (RCP) during circulatory arrest in adult aortic surgery using cerebral oximetry.MethodsThis was a cross-sectional analytic study that enrolled a total of 84 patients undergoing total circulatory arrest during adult aortic surgery divided into two groups.

Prediction of aneurysm rupture has been a great challenge for decades. We report a successful rupture site prediction on a 97 mm abdominal aortic aneurysm (AAA). A 73-year-old man with an 11-year history of AAA presented to our outpatient clinic with a one-week history of hemoptysis.
