The Analysis of Reoperation Causes After the Correction of Partial Atrioventricular Communications and Their Results

The aim of the investigation is the analysis of the causes of reoperations after correction of partial atrioventricular communications and their results.

Materials and Methods. 20 patients were reoperated for complications caused by the correction of partial atrioventricular communications. Along with physical examination, all the patients underwent electrocardiography, chest X-ray, and transthoracic echocardiography. In a few cases additional angiography was performed. The operations were performed by standard technique using split-sternum medium approach. All patients underwent normothermic perfusion with aorta occlusion under the conditions of pharmaco-hypothermic cardioplegia.

Results. The lethality in the analyzed group in short-term postoperative period was 15%. The most reoperations were due to progressive mitral insufficiency (65%), as well as recanalization of atrial septal defect (20%). The main causes of complications were surgical technique breakdown (24%), and progressive connective tissue dysplasia (41%). Reoperations after the correction of partial atrioventricular communication have good and satisfactory results in 94% of cases in long-term period.
