Investigation of left ventricular changes according to valve type in patients with surgical replacement due to isolated aortic stenosis.

Objective: The aim of this study was to investigate postoperative left ventricular changes [left ventricular mass (LVM), left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), patient-prosthesis mismatch (PPM), pulmonary artery pressure (PAP), gradients, and ejection fraction (EF)] according to the valve type used in patients undergoing aortic valve replacement (AVR) due to isolated aortic stenosis.

Methods: A total of 199 patients with isolated AVR due to aortic stenosis between 2010 and 2020 was retrospectively investigated. Four groups were identified according to the valve type used (mechanical, bovine pericardium, porcine and sutureless).

Experience of Replantation and Reconstruction in Total Scalp, Partial Forehead, and Ear Avulsions.

In this study, the authors present the challenges of replantation and management of 2 patients who have total scalp, partial forehead and ear avulsion. A 39-year-old male farmer was admitted to the emergency room with the total scalp, forehead, partial right eyebrow and upper eyelid amputation after his hair was catched by an agricultural machine. Anastomoses of 2 arteries and 2 veins in the occipital region were done first.
