Transannular Patch

Background: Tetralogy of Fallot (TOF) is one of the most common congenital cardiac defect. In patients with small PV annulus, it has to be augmented to certain diameter by cutting annulus. In these cases, transannular patch is used free PR is inevitable. Free PR with transannular patch ultimately leads to RV dilatation, dysfunction, arrhythmia and failure with time. Monocuspid reconstruction of PV is commonly practiced in many centers but its long-term outcome is poor though it helps to achieve a less stormy ICU course. Modified monocusp or bicuspid PV reconstruction is a good choice where 0.1mm PTFE patch is used. Objectives: We are presenting the results of bicuspid PV reconstruction using a 0.1mm PTFE patch as a method of RVOT reconstruction in repair of TOF with transannular patch. Methods: A total, 42 patients diagnosed as TOF were treated from January 2016 to October 2020. Age range 18 months to 35 years, weighing 10 kg to 70 kg. 38 patients had TOF, 4 had DORV with PS. The transannular patch was followed by implantation of a 0.1-mm PTFE modified monocusp valve using posterior fixation. Results: Among total patients 28 were male and 14 were female. Mean age 9.58±5.6 yrs. Bypass time was 187±31 min, cross-clamp time 123.63±25.42 min. Out of 42 patients, PR gradient was trivial in 7(16.67%), mild in 31(73.1%), moderate in 4(9.52%) patients. First, a follow-up echocardiogram revealed no significant deterioration of PR gradient. ICU stay was 89±32.6 hours and mean hospital stay 11.48±2.1 days. Conclusion: Initial results using a transannular patch with a modified monocusp valve to repair the outflow tract in cases of Tetralogy of Fallot were excellent. There were only a slight pressure gradient and mild regurgitation in most of the cases. DS (Child) H J 2020; 36(2): 114-119

Abstract OBJECTIVES The right ventricular outflow tract reconstruction is a common necessity in congenital cardiac surgery. As homograft availability is limited, alternatives need to be evaluated. The Labcor® conduit consists of a porcine tricomposite valve assembled inside a bovine pericardium tube. This study presents intermediate-term results for its utilization for right ventricular outflow tract reconstruction. METHODS Labcor conduits were implanted in 53 patients (February 2009–July 2016). We analysed perioperative data, freedom from conduit failure and risk factors for conduit dysfunction. RESULTS The most common diagnosis was Tetralogy of Fallot (n = 20, 37.7%). The median age at surgery was 10.0 [interquartile range (IQR) 4.9–14.3] years. Pulmonary artery plasty (n = 37, 69.8%) and augmentation of the right ventricular outflow tract (n = 16, 30.2%) were often part of the procedure. The median conduit size was 21 (range 11–25) mm. There was no in-hospital death. The median follow-up after surgery was 4.6 (IQR 3.4–5.6) years. Fourteen patients (27.5%) developed conduit failure with stenosis being the main cause. Freedom from conduit failure was 98.0% at 2 and 80.5% at 5 years. The median longevity of the conduit was 7.4 years (95% confidence interval 5.1–9.8 years). Younger age and smaller conduit size were related to conduit failure. CONCLUSIONS Utilization of the Labcor conduit revealed acceptable intermediate-term results. The conduit appeared to be functioning sufficiently well within the first 5 years in the majority of patients. The higher rate of failure concerning smaller conduits might be associated with somatic outgrowth; however, conduit degeneration as common and long-term outcome still needs to be evaluated.
