“…Comparing to these results, autologous unpreserved pericardium has been shown to be a durable tissue that is pliable and easy to handle and suture [1]. The conduit we have prepared from unpreserved pericardium can be used in TGA (Transposition of Great Arteries) (either dextro-TGA or Levo-TGA), VSD and LVOTO (left ventricular outflow tract obstruction), broadening its application.…”

“…An ideal valved conduit still remains the Holy Grail in cardiac surgery. It should comply with the following requisites: (1) some potential for its diameter to increase with time, (2) low likelihood of shrinkage or development of intimal peel or thrombus, (3) long-lasting valve function, (4) ready availability, and (5) low cost [1].…”

“…The first patient with a non-valved pericardial conduit, who has been followed up for more than 30 years, has not had to undergo reoperation [1]. After the wide experience with the use of unpreserved pericardium in the reconstruction of the right ventricular outflow tract in ToF, Schlichter Andrés J. et al produced excellent results [1]. We created and modified later a tricuspid valved conduit instead of Schlichter's bicuspid conduit by studying the normal pulmonary and aortic valve cusp diameters and cusp shapes [4] [5] [6].…”

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.

It is uncertain how long catheter delivered percutaneous heart valves may last. In congenital cardiology, stenosis and regurgitation of right ventricular to pulmonary artery conduits and valves is common, leading to repeated operations for young patients with concomitant mortality and morbidity. It has also been unclear whether percutaneous pulmonary valves last as long as surgical pulmonary valves. When the current generation of the percutaneous pulmonary valve was first implanted in the United Kingdom from 2003, randomized trials were initially not performed, decided on a case‐by‐case basis in congenital cardiology, nor long‐term registries kept. We describe three cases where such percutaneous heart valves have lasted up to 19 years. All valves were working without significant stenosis and minor degrees of regurgitation on long‐term echocardiographic follow‐up, patients being asymptomatic. This demonstrates that percutaneous pulmonary valves can achieve long‐term durability and may prevent the need for otherwise high‐risk surgery in congenital cardiac patients.
