Mitral valve repair is more challenging in rheumatic etiology due to complexity of lesions. This prospective randomized case control study was designed to evaluate repair through mini right thoracotomy and to compare the clinical and echocardiographic outcomes with sternotomy in rheumatic patients. Methods: 25 patients of rheumatic heart disease underwent mitral valve repair through mini right thoracotomy (group I). Various clinical and functional parameters were compared with 25 patients of mitral valve repair through sternotomy (group II). On follow up the results were compared in both groups for clinical and echocardiographic parameters. Results: The various pre-operative demographic parameters were comparable in two groups. Equal rate of mitral valve repair (group I-21/25, 84% and group II-21/25, 84%) was achieved in both groups. The various intra-operative and post-operative clinical parameters were better in group I .There were equivalent functional and valve related outcomes in both groups in term of NYHA class (1.28 ± 0.613 vs 1.08 ± 0.276, P = 0.144), post-operative mitral valve area (2.43 ± 0.891 vs 2.82 ± 0.662, P = 0.090), incidence of more than mild mitral regurgitation (0) and mean pressure gradient across mitral valve (4.98 ± 3.33 vs 4.23 ± 1.5, P = 0.309). Conclusion: Mitral valve repair through mini right thoracotomy approach in rheumatic etiology is feasible and safe with equivalent rate of successful repair as compared to median sternotomy. It is associated with lesser morbidity, cosmetic advantage and lesser resource utilization.展开更多

Methods: Ninety-eight patients requiring cardiac surgeries were operated through this approaach. Incisions were made in the fourth or on intercostal space. The upper costal cartilage near the incision was routinely removed. Aortic cannulation was performed through the lateral wall of the aorta. The procedures on the heart itself were the same as that of the median sternotomy. Results: The average lengths of the incisions, for the male and female patients, were (10.6±3.2) cm and (10.3 ± 2.2) cm respectively. The mean bypass time was (61.3 ±t 25. 1) min, and the mean heart arrest time was (49.5±19.2) min. The postoperative drainage was (410± 125) ml. All but 1 patient with aortic valve operation had satisfactory exposure . The complications included chest pain (n = 5), rib fracture (n =3), pleural effusion (n=5), and pneumothorax(n=6). Conclusion: The right anterolateral tholacotomy was a satisfactory alternative of median sternotomy for the surgeries that can be performed through a right atrium access.展开更多
