Abstract

Objective: To compare the cross-clamp times between the semi-continuous and interrupted techniques for mitral valve replacement. Study Design: Retrospective Cohort study. Setting: Peshawar Institute of Cardiology Tertiary Cardiac Centre in Lower Middle-Income Country with high rheumatic heart disease burden. Period: January 2021 to June 2024. Methods: The patients were divided into two equal groups: Group I patients underwent semi-continuous technique for mitral valve replacement, and Group II underwent interrupted technique. All patients older than 18 years with isolated mitral valve replacement for rheumatic mitral disease (confirmed either with gross features or biopsy) were included. Results: A total of 110 patients were included in the analysis, consisting of 46 males (41.8%) and 64 females (58.2%). The mean age of the cohort was 39.8 years (SD = 11.5), with a mean body mass index (BMI) of 23.3 (SD = 4.2). The mean cross-clamp time for the semi-continuous technique was 68.75 minutes (SD = 22.2), which was significantly lower than the mean cross-clamp time of 91.7 minutes (SD = 27.3) for the interrupted technique. Conclusion: Study showed that the semi-continuous sutures gave a similar outcome to the interrupted sutures, with significantly better operative time regarding cross-clamp time without increasing mortality.
