Prevalence of CHD in imperforated anus in patients referring to Booali Cina hospital from 1996 to 2003.(Is echocardiography required prior to surgery?)

Background and Imperforated anus is a disease that requires surgery in the first days of life therefore, association with other diseases or anomalies is of great importance. This study aims to determine the prevalence of Congenital Heart Disease (CHD) in patients with imperforated anus. This is a descriptive study on patients with imperforated anus referring to Booali hospital of Sari, IRAN from 1996 to 2003. Previous patients medical records was reviewed and physical examination and concurrently echocardiography were done for new patients. The data were subjected to descriptive statistical analysis using SPSS software. Ninty patients with imperforated anus were entered into the survey. Echocardiography revealed that 26 patients including 14 Female (57.2%) and 12 Male (42.8%) had CHD. 22 of CHD patients (84.6%) had imperforated anus(IA) of high type and 4 (15.3%) had IA of low type. CHD types consisted of: 7 patients (26.9%) ASD+PDA, 6 patients (23%) ASD+PDA+TR, 4 patients (15.3%) PDA, 4 patients (15.3%) MR, 1 patient (3.8%) TF, 2patients (7.6%) VSD and 2 patients (7.6%) ASD. Considering the high prevalence of CHD in IA, it seems that echocardiography is necessary in all those with IA particularly to predict outcome of surgery and prevent probable complications.
