Tetralogy of Fallot in adults--107 cases.

ABSTRACT

Clinical and haemodynamic profile of 107 adult patients above the age of 15 years with TOF was analysed. Cardiac catherization and selective cine-angiography were performed in all cases. Infundibular pulmonary stenosis, mal-alignment type of ventricular septal defect, mitral-aortic fibrous continuity and equal systolic pressures in both the ventricles and aorta were considered mandatory for the diagnosis of Tetralogy of Fallot. Aortic regurgitation was seen in 26 cases (24%), tricuspid regurgitation in 22 cases (21%), absent pulmonary valve in 3 cases (3%), branch pulmonary artery stenosis in 9 case (8.4%), major aortopulmonary collaterals in 15 cases (14%), right atrial pressure was more than 10 mmHg in 10 cases (11%) and right ventricular end diastolic pressure more than 9 mmHg in 73 cases (68%). The left ventricular end diastolic pressure was above 13 mmHg in 58 cases (54%).
