Experience of Fontan surgery at Armed Forces Institute of Cardiology /National Institute of Heart Diseases [AFIC-NIHD]

ABSTRACT

To assess the overall outcome and success of Fontan surgery at our institute. AFIC-NIHD Rawalpindi. 01 September 2005 to 31 March 2010. For this retrospective study, institute's cardiac surgery database was used. Patients of single ventricle physiology, who had normal Left Ventricular End-diastolic Pressure and pulmonary artery pressures, were included. Data was analyzed using SPSS version 16. A total of 34 Fontan procedures were done. The mean age at operation was 4.83 +/- 1.37 years. There were 22 [64.7%] males and 12 [35.3%] females. Twenty five [73.5%] had a staged Fontan [successful previous Bidirectional Glenn's shunt, BDG]. Nine [26.5%] were primary Fontan procedures [no successful previous Bidirectional Glenn's shunt, BDG]. Thirty two [94.8%] were Extra Cardiac Conduit Fontan [ECCF] and 2[5.8%] were Intra Cardiac Fontan. Mean Bypass time was 132.65 +/- 48.44 minutes. Aorta was cross clamped in intracardiac Fontan and its mean time was 43.31 +/- 5.85minutes. Fenestration was employed in 14 [41.2%] patients. Mean pre-operative oxygen saturations were 77.41 +/- 10.27%, which significantly increased to 93.94 +/- 3.96% post-operatively [p<0.001]. In-hospital mortality was 2 [5.8%]. Fontan surgery has acceptable morbidity and mortality in our set up
