Cardio-cutaneous fistula is a very rare complication of cardiac surgery, and the optimal management strategy is unclear. We present a case of a right ventricle-to-pulmonary artery conduit (RV-PA) forming a cutaneous fistulate that was successfully surgically repaired. A 43-year-old male presented for an elective RV-PA conduit replacement with a cutaneous skin lesion and associated sub-sternal collection. The patient underwent redo-sternotomy for the previous surgical replacement RV-PA conduit, of pulmonary atresia, ventricular septal defect, and ligation of main aorto-pulmonary collateral arteries in childhood, with the subsequent upgrade of the RV-PA conduit using pulmonary homograft. Upon entry into the thoracic cavity, it was clear that there was a direct fistula formed from the RV-PA conduit that was responsible for the skin lesion and hence a direct communication to the PA. We discuss the surgical method and surrounding discussions regarding Cardio-cutaneous fistula in a successful surgical repair when the pathology is difficult to truly identify preoperatively.

Background: The standard aortic valve replacement operations in young patients are bioprosthetic or mechanical aortic valve replacement. In this study, we present the long-term results of the Ross operation in young patients.
Methods: The Ross operation with root replacement was performed on 795 patients between 1995 and 2020.

Background: The repair of certain types of complex congenital cardiac defects may require a right ventricle-pulmonary artery (RV-PA) conduit. Using the Ozaki Aortic valve neocuspidization (AVNeo)technique, a valved RV-PA conduit was constructed with an Ozaki valve inside a Dacron graft. This study aims to evaluate the short-term outcome of the Ozaki valved RV-PA conduit.

Controlling pulmonary blood flow in patients who have undergone Norwood palliation, especially early postoperatively, is challenging due to a change in the balance of systemic and pulmonary vascular resistance. We applied a combination therapy of clipping and balloon angioplasty for right ventricle-pulmonary artery (RV-PA) shunt to control pulmonary blood flow, but the influence of the combination therapy on the PA condition is uncertain. Retrospectively analysis was conducted of all infants with hypoplastic left heart syndrome who had undergone Norwood palliation with RV-PA shunt at Okayama University Hospital from January 2008 to September 2022.

Surgical implantation of a right ventricle to pulmonary artery (RV-PA) conduit is an important component of congenital heart disease (CHD) surgery, but with limited durability, leading to re-intervention. The present single-center, retrospective, cohort study reports the results of surgically implanted RV-PA conduits in a consecutive series of children and adults with CHD. Patients with CHD referred for RV-PA conduit surgical implantation (from October 1997 to January 2022) were included.

Article Synopsis
- Percutaneous pulmonary valve implantation (PPVI) is a catheter-based treatment for right ventricular outflow tract (RVOT) dysfunction, which can lead to serious complications if valves are improperly sized.
- Researchers developed a more efficient method using patient-specific finite element (FE) models to assess risks before the PPVI procedure, significantly reducing computation time from hundreds of hours to just 2-6 minutes on a desktop computer.
- The study showed that changes in the diameter of surrounding arteries predicted complications like aortic valve insufficiency and coronary artery compression accurately for all patients evaluated, indicating strong agreement between the FE model predictions and actual clinical outcomes.
