 71 Summary SUMMARY This study was conducted in the cardiothoracic surgery department, Kasr El-Aini Hospital, Cairo University in the period between June 2020 and February 2022. Forty patients with bicuspid aortic valve with ascending aortic aneurysm were subjected to aortic valve repair surgery. The aim of this study was to evaluate early outcomes of valve preservation in patients with ascending aortic aneurysm and bicuspid valve disease. Careful analysis of failure has identified BAVs that are likely not to be suitable substrates for repair and have contributed significantly to the reduction of morbidity and mortality in aortic valve surgery over the past decades. Prospective data were collected 40 patients with bicuspid aortic valve with ascending aortic aneurysm were treated surgically with aortic valve repair surgery. Patients were reviewed and data analyzed regarding preoperative demographic data (sex, age, echocardiographic findings, associated diseases if present), intra-operative (bypass time, cross clamp time, repair type and TEE findings as degree of regurge) and post- operative parameters (ICU stay, duration of ventilation, inotropic support (type and dose), any complications; e.g. 30 days hospital mortality. Results: All our patients showed significant improvement regarding left ventricular dimensions and contractility. 2 patients had mild to moderate regurge and 38 patients had non significant regurge in the six month follow up echo. one patient complicated by complete heart block required permanent pacemaker implantation, another two patients
