Pattern of un-operated Grown Up Congenital Heart (GUCH) patients presenting to a Tertiary Care Cardiac Institute of Punjab.

Objectives: To identify the pattern of un-operated grown up congenital heart defects at our tertiary care cardiac institute.

Methods: This is a prospective observational study. All un-operated GUCH patients who presented to Faisalabad Institute of Cardiology (FIC) from May 2017 to 30th July 2017 were enrolled. Diagnosis was established on Transthoracic Echocardiography done by dedicated pediatric cardiologist at FIC. The mode of presentation, presenting complaints, type, severity, complications and co-morbid conditions of CHD were recorded.

Results: A total of 200 consecutive patients were enrolled. Mean age was 29.92 ± 11.21 years. There were 104 females (52%) and 96 males (48%). Majority of patients presented in Out-Patient Department (84%) while 16% presented in emergency (n=32). The most common cardiac anomalies were: Atrial Septal Defect (ASD) 41.5% (83), Tetralogy of Fallots (TOF) 42 (21%), Ventricular Septal Defect (VSD) 28 (14%) and Patent ductus arteriosus (PDA) 8 % (16). Cyanotic CHD was present in 43% (86) while TOF was the most common of it. The disease was of moderate complexity in 77.5% patients. Certain complications like Pulmonary hypertension 69(34.5%), Eisenmenger 33(16.5%), Rhythm disturbances 15 (7.5%), Infective endocarditis 5(2.5%) were also present along with co-morbid conditions like coronary artery disease (1.5% and systemic hypertension (2.5%). Dyspnea on exertion (59.5%) followed by cyanosis (41%) were the most common presenting complaints. The most common reason for hospital admission was cardiac signs and symptoms (19.5%) followed by cardiac catheterization (10.5%).

Conclusion: The ASD, TOF, VSD and PDA remain the most common CHD in descending order while pulmonary hypertension, Eisenmenger, heart failure, arrhythmias, infective endocarditis and stroke were the common complications of CHD at this particular age.
