[MSB-45] Minimally Invasive Mitral Valve Surgery in Fibrillation or Beating Heart: A Comparative Study.

Objective: This aimed to share our results of minimally invasive mitral valve surgery in fibrillation or beating heart.

Methods: The postoperative outcomes of 33 patients (mean age: 61.7 years) who underwent mitral valve surgery in fibrillation (n=14) or beating heart (n=19) with minimally invasive methods between February 2019 and May 2024 were retrospectively analyzed.

[MSB-47] Minimally Invasive Cardiac Surgery with Subareolar Incision.

Objective: This study aimed to share the results of minimally invasive cardiac surgery performed with a subareolar incision at our clinic. Eight female patients (mean age: 54±14.16 years) who underwent minimally invasive cardiac surgery with a subareolar incision between April 2023 and August 2024 were included in this retrospective study.

Evaluation of the effects of rosmarinic acid on red blood cell deformability, morphology, and nitric oxide in rat lower limb skeletal muscle ischemia-reperfusion injury.

Background: Erythrocyte deformability, the ability of red blood cells to bend and twist as they pass through capillaries, is es-sential for tissue perfusion. This study investigates the effects and underlying mechanisms of rosmarinic acid treatment on erythrocyte deformability in rats subjected to lower limb ischemia-reperfusion injury.

Methods: The study was conducted on Wistar albino rats weighing 400-450 g.
