ReviewModified simple sliding aortoplasty for preserving the sinotubular junction without using foreign material for congenital supravalvar aortic stenosis.
The surgical approach for treating supravalvar aortic stenosis (SVAS) has evolved from a plain patch technique to a three-dimensional patch repair, which has some drawbacks. Here, we report on the midterm outcomes after using our modified simple sliding aortoplasty preserving sinotubular junction without foreign material for surgical correction of SVAS. ⋯ Our modified simple sliding aortoplasty showed excellent surgical results, and may be a good option for discrete SVAS.

Multicenter Study Clinical TrialClinical experience with the ATS 3f Enable® Sutureless Bioprosthesis.
The ATS 3f Enable® Bioprosthesis is a self-expanding valve with a tubular design that allows for decreased leaflet stress and preservation of aortic sinuses. We report the midterm results of a prospective, multicenter clinical study evaluating the safety and efficacy of this stented bioprosthesis in patients undergoing isolated aortic valve replacement with or without concomitant procedures. ⋯ The sutureless valve implantation technique is feasible and safe with the ATS 3f Enable Bioprosthesis. Valve implantation resulted in excellent hemodynamics and significant clinical improvement. Overall, these data confirm the safety and clinical utility of the Enable® Bioprosthesis for aortic valve replacement.

Extracorporeal membranous oxygenation support for acute fulminant myocarditis: analysis of a single center's experience.
Acute fulminant myocarditis (AFM) is a disease category that is easily neglected. Circulatory mechanical support is sometimes required for this devastating condition. We analyzed our experience in managing AFM with mechanical circulatory support. ⋯ AFM still carries high mortality rates in spite of advanced mechanical support. Most of the survivors did not require transplantation and could return to good lifestyle. Due to its simplicity and effectiveness, ECMO can be a first-line tool to rescue this group of patients.

Logistic risk model predicting postoperative renal failure requiring dialysis in cardiac surgery patients.
Renal failure requiring dialysis represents a serious complication following cardiac surgery. This study was designed to determine the incidence and predictors of renal failure requiring dialysis in a contemporary patient population. We also aimed to create a model based on these risk factors that could serve as a tool for the prediction of renal failure requiring dialysis. ⋯ Renal failure requiring dialysis remains a serious complication, particularly in patients with pulmonary hypertension and previous renal dysfunction. Our logistic risk model allows the prediction of renal failure requiring dialysis, based on the individual presentation of risk factors and, therefore, helps to determine the perioperative risk in cardiac surgery patients.

Right ventricle-to-pulmonary artery shunt related complications after Norwood procedure.
The right ventricle-to-pulmonary artery (RV-PA) shunt in the Norwood procedure (NP) for children with hypoplastic left-heart syndrome (HLHS) provides stable early hemodynamics and improves survival in many centers. However, lower pulmonary-to-systemic flow ratio causes early cyanosis and may require earlier second-stage procedure. The aim of the study was to present shunt-related results after NP with RV-PA shunt and our technique of RV-PA shunt construction. ⋯ The RV-PA shunt can be a safe and efficient technique in providing optimal pulmonary blood flow in the children with HLHS after Norwood procedure, performed with minimal rate of complications. In our experience, the use of RV-PA shunt in NP does not require earlier second-stage procedure.
