Background: In mitral valve prolapse is associated with severe mitral regurgitation, mitral valve repair
or surgical replacement may be necessary. In Mitral valve replacement, some surgeon use continuous
suture, others use interrupted suture technique.
Aim of the work: to compare efficacy of semi-continuous technique & interrupted suture of prosthestic
valve replacement in mitral valve replacement.
Patients and Methods: it was a prospective randomized comparative study done at the Cardiothoracic
Surgery Department, Qena University Hospitals, South Valley University, Egypt between April 2016 to
April 2018. It included 31 patients with rheumatic mitral valve disease whatever the cause. They were
divided into group1: patients underwent semi-continuous technique for MVR (18 cases) and group2:
patients underwent interrupted technique (13 cases).All of patients were subjected to preoperative data:
complete history, general examination including general condition of the patient and vital signs,
investigations including routine laboratory investigations, especially complete blood count, chest X ray
(CXR), 12 lead Electrocardiography (ECG), echocardiography and coronary angiography if patient
more than 40 years old, operative data including total bypass time, aortic CCT, number of sutures, and
postoperative outcome including ICU stage and inotrope use, postoperative complications, pulmonary
hypertension and echo findings as immediate postoperative and echo after 1 and 3 months
postoperative.
Results: We found that the mean total bypass time was significantly higher among interrupted group < br />compared to semicontinuous one.
Conclusion: Semicontinuous sutures showed significantly better results than interrupted ones,
especially regarding the total bypass time
