Abstract:
Objective To explore the application of echocardiography to guide interatrial septal puncture and evaluate the clinical effect in PBMV. Methods One hundren and sixty two patients were categorized into two groups according to whether echocardiography was applied in atrial septal puncture and real time monitoring. X-ray fluoroscopy guidence was used during atrial septal puncture in group 1 and in group 2, X-ray as well as echocardiography were used. The clinical outcomes were analyzed and contrasted between the 2 group. Results (1) The mean mitral pressure gradient dropped obviously in group 2 immediately after PBMV compared with group 1 (6.4?2.6 mm?Hg vs 10.2?3.7 mm?Hg,P
