Abstract

 Background: The interest in BEATING HEART surgery is growing since better results can be obtained with this procedure compared to conventional myocardial protection techniques using cardioplegic solutions. This led us to consider MITRAL VALVE replacement with BEATING HEART.Objectives: This study aimed to determine the safety and efficacy of BEATING HEART MITRAL VALVE replacement without cross clamp.Methods: This prospective study was conducted on the patients with isolated MITRAL VALVE disease requiring MITRAL VALVE replacement according to ACC / AHA guidelines. In this study, 15 patients underwent MITRAL VALVE replacement using BEATING HEART technique (Group A) and 15 ones underwent MITRAL VALVE replacement using arrested heart technique (Group B). The patients were randomized using block randomization. The data were analyzed using the SPSS statistical software.Results: Preoperative parameters were comparable in the two groups. Most of the patients in both study groups were in NYHA class III or IV. Postoperatively, however, most of the patients in the two groups were either in NYHA class I or II. No mortality occurred in the BEATING HEART group, while one mortality occurred in the arrested heart group. The results showed a significant difference between the two groups regarding the mean bypass time, mean operating time, mean ICU stay, and mean length of hospital stay.Conclusions: BEATING HEART MITRAL VALVE replacement is equally safe as the arrested heart technique. Thus, it is recommended as an appropriate alternative to the arrested heart technique for MITRAL VALVE replacement.
