Objective: This study aimed to share our surgical experience of patients with hypertrophic cardiomyopathy (HCM) treated successfully with surgical myectomy at a tertiary center that frequently utilizes minimally invasive approaches in clinical practice.

Methods: This study was conducted with eight patients (5 males, 3 females; mean age: 49.2±12.

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.

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.

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.

Background: This study aimed to evaluate the efficacy and safety of total coronary revascularization via left anterior thoracotomy (TCRAT) by comparing it to conventional coronary artery bypass grafting (CABG) with median sternotomy.

Methods: In this retrospective study, 108 patients (95 males, 13 females; mean age: 57.1±8.

Intravascular shrapnel or bullet embolization after a gunshot injury is rare, with fewer than 200 cases reported over the past century. Military injuries typically have high energy transfer, making this phenomenon less prevalent. A 22-year-old military personnel presented with chronic leg ischemia resulting from arterial bullet embolization.

Article Synopsis
  • Erythrocyte deformability is essential for tissue perfusion, and this study investigates how Thymoquinone affects this property in rats with lower extremity ischemia-reperfusion injury.
  • Researchers divided Wistar rats into five groups, including a control and various Thymoquinone treatment groups, to examine its effects on erythrocyte deformability and other markers post-injury.
  • Results showed that Thymoquinone significantly improved erythrocyte deformability and morphology while increasing the activity of endothelial nitric oxide synthase compared to the untreated ischemia-reperfusion group.*

Cases of embedded unexploded ordnance are extremely rare and pose a risk to bystanders and health providers. A patient arrived at the Role 2 medical facility in the Turkish army, whose left arm was amputated due to a terrorist attack and major hemorrhages had been halted by clamping of the left subclavian artery and vein. A piece of metal wire running from the lateral chest wall was detected as an unexploded ordnance piece and it was removed surgically.

Background: The aim of this study was to compare the early results of rapid deployment aortic valves (RD-AVR) and aortic valve neocuspidization (AVNeo) techniques.

Methods: Between December 2019 to May 2022, 104 patients were operated on with aortic stenosis by RD-AVR (N = 52) and AVNeo (N = 52) techniques. Patients with isolated aortic valve stenosis and aortic stenosis concomittant with planned other cardiac surgeries were included.

Introduction: Robotic mitral valve surgery is a challenging issue, particularly in patients who are not suitable for aortic cross-clamping. In this study, we aimed to determine the feasibility and benefits of robotic, beating heart mitral valve surgery.

Methods: From February 2019 to February 2022, 17 patients underwent robotic beating heart mitral valve surgery.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe disorders, characterized by necrosis and epidermal detachment. Most important known acquired etiological factor is medications. Warfarin is one of the most common medications of cardiac valve surgery, which may rarely cause SJS or TEN.
