Background: Despite a wide variety of mitral prosthesis suturing, pledgeted annular sutures are preferred to lower the incidence of para-valvular leakage (PVL). However, there is limited evidence in the literature on the effect of non-plegeted sutures on such serious complication. Objective: The purpose of this study was to determine the safety and practicality of employing non-pledgeted sutures for Mitral valve replacement (MVR), especially regarding postoperative PVL. Patients and methods: Data on 100 patients with MVR were gathered from Cairo University Hospitals. Cases were split into two groups: group 1 underwent surgery using non-pledgeted horizontal sutures where in group 2 we used Teflon-pledgeted sutures. Preoperative, operative, and postoperative factors including follow-up echocardiographic examination one year following discharge, were compared between the two groups. Results: Both groups had similar preoperative characteristics, with group 1 including 49 patients compared to 51 patients in group 2. Data showed significantly shorter cross clamping (AXC) time in group 1 (p value < 0.05), intraoperative TEE has never observed para-prosthetic leakage in both groups, there was no significant difference regarding both mean ICU and hospital stay.

Background: Postintubation tracheal stenosis (PITS) is caused by a number of etiologies demanding mechanical ventilation and application of endotracheal or tracheostomy tubes which in turn conflict regional ischemic necrosis of the airway at various levels, presenting the characteristic signs and symptoms of airway obstruction. The incidences of PITS have been decreased with the recognition of the causes, and modification of endotracheal tubes and methods of management. Patients and Methods: Fifty four patients were identified between June 2017 and June 2019. Those patients were treated for tracheal stenosis which developed after prolonged endotracheal intubation. The study was done in Cardiothoracic Surgery departments at Kasr-Alainy Hospital (Cairo University). Patients were managed by rigid bronchoscopic dilatation, airway devices (as Montgomery t-tube or metallic stent) and/or primary tracheal resection and end to end anastomosis. Results: Out of the 54 patients: Three (5.5%) were planned for tracheostomy from the start. Fifty-one (94.4%) were subjected to rigid bronchoscopic examination & dilatation. Three patients (5.5%) were fully improved after bronchoscopic dilatation. The rest of the patients (48) were directed to the next stage in our management, either staged management or resection anastomosis.
