ABSTRACT: Objective: To study early results of hand
made fresh (autologous/homologous) pericardial valved
conduit in achieving right ventricle to pulmonary artery continuity. Method: Between November 2014 and September 2015, 19 cases, with diagnosis of
Tetralogy of Fallot with Pulmonary stenosis (PS) or Pulmonary
atresia (PA) underwent intracardiac repair and Right Ventricular Outflow Tract
(RVOT) reconstruction with hand made fresh [autologous (n = 2)/ homologous (n =
17)] pericardial valved conduit. Mean age of the patients at time of surgery
was 6.37 years (range 3 months to 18 years), mean weight was 18.52 kilograms
(range 6 kg to 40 kg) and mean size of the conduit was 20.7 mm (range 16 mm to 24 mm). Results: All patients had a smooth post-operative course, with mean ICU (Intensive Care Unit) stay of 3.6
days (range 3 days to 6 days) and mean
post-operative hospital stay 8.5 days (range 7 days to 16 days). Intra-operative
and Post-operative echocardiography revealed moderate Pulmonary
regurgitation (PR) in one patient, mild PR in 5 patients and no or trace PR in
13 patients. No patient has developed conduit stenosis or calcification till now. Conclusion: Autologous or homologous pericardial valved conduit provides good early results and is
especially suitable for developing world
because of zero cost. Long term usefulness of such option remains to be
confirmed in terms of dilation, calcification and freedom from intervention.
