Frequency of atrial septal defect in patients of rheumatic mitral stenosis undergoing percutaneous transseptal mitral commisurotomy.

Abstract

Objectives: To determine the frequency of atrial septal defect in patients of rheumatic mitral stenosis undergoing percutaneous trans septal mitral commissurotomy. Study Design: Cross sectional study. Setting: Faisalabad Institute of Cardiology, Faisalabad. Period: 15-07-2018 to 14-01-2019. Material & Methods: Study was approved by hospital ethical committee. A total of 45 patients were included in the study that fulfilled the study inclusion criteria and gave written informed consent. PTMC was performed using Inoue balloon technique through right femoral venous route under local anesthesia. Transthoracic echocardiography was done after 48 hours of PTMC for ASD assessment. Results: Out of 45 patients there were 17 (37.8%) males and 28 (62.2%) females. The mean age was (29.06±10.85) years. There were 9 (20%) patients with NYHA functional class II, 28(62.2%) with NYHA functional class III and 8(17.8%) with NYHA functional class IV symptoms. ASD was detected in 15 (33.3%) patients after 48 hours of PTMC. Conclusion: In this study frequency of ASD in patients of mitral stenosis undergoing PTMC was 33.3%. Results of this study can help to identify the patients who will be potential candidates for closure of residual ASD.
