Aim and Objectives: Mitral valve disease is associated with severe mitral valve stenosis, and mitral valve regurgitation warrants a mitral valve repair or surgical replacement. Cardiothoracic surgeons use semi-continuous sutures or interrupted suture techniques in Mitral valve replacement. The study's primary aim was to compare the efficacy of the semi-continuous and interrupted suture techniques of prosthetic valve replacement in mitral valve replacement surgeries during the early postoperative period. Materials and Methods: a prospective randomised comparative study was conducted at the CTVS Department, GB Pant Hospital, New Delhi, India. The 100 patients with mitral valve disease (with any pathology) were included in the study from Jan 2020 to Dec 2021. They were divided randomly into two groups, group1 included patients who underwent semicontinuous technique for MVR (45 cases), and group2 included the patients who underwent interrupted technique (55cases). Data related to complete history, general examination including vital signs, investigations including complete blood count, chest X-ray (CXR), 12 lead Electrocardiography (ECG), echocardiography and coronary angiography were recorded preoperatively, and if the patient was more than 40 years old, operative data including total bypass time, aortic CCT of both groups were recorded and postoperative outcome including ICU stay and inotrope use, postoperative complications, pulmonary hypertension and echo findings as immediate postoperative and echo after 1 and 3 months postoperative was also recorded. Data were analysed with the help of SPSS 20 software Results: Both the groups were comparable in terms of age, gender and preoperative echocardiographic characteristics (p>0.05 each). Total bypass and cross-clamp times were significantly higher in patients who underwent interrupted technique. Conclusions: Semi-continuous technique was found to be a safe and reliable method of mitral valve replacement. It was found that the mean total bypass time and cross-clamp times were significantly higher among the interrupted group compared to the semi-continuous suturing group. [ABSTRACT FROM AUTHOR] |
