Background: Extracardiac conduit Fontan procedure (ECFP) employing a Gore-Tex conduit has been widely used for patients with single ventricle physiology; however, the long-term status of the conduit is unknown. We investigated the changes in a Gore-Tex conduit after ECFP and the factors associated with its narrowing.

Methods: We conducted a retrospective analysis of 86 patients who underwent ECFP between January 1995 and December 2008 and had cardiac computed tomography (CT) during the follow-up period.

Pulmonary Artery Angioplasty for Improving Ipsilateral Lung Perfusion in Adolescent and Adult Patients: An Analysis Based on Cardiac Magnetic Resonance Imaging and Lung Perfusion Scanning.

Background: The left pulmonary artery (LPA) may be kinked and stenotic, especially in tetralogy of Fallot, because of ductal tissue and anterior deviation of the conal septum. If LPA stenosis is not effectively treated during total correction, surgical angioplasty is occasionally performed. However, whether pulmonary artery (PA) angioplasty in adolescents or adults improves perfusion in the ipsilateral lung remains unclear.

This study compared clinical outcomes between operating room extubation and ICU extubation after open-heart surgery in patients with CHD.

Methods: We retrospectively reviewed 215 patients who underwent open-heart surgery for CHDs under the scheduled "Fast track" protocol between September 2016 and April 2022.

Shallow suture at ventricular septal defect may safely reduce right bundle branch block.

Background: To avoid rhythm disturbance, sutures for ventricular septal defect closure have been traditionally placed 2∼5 mm or more away from the edge of the ventricular septal defect. However, the traditional suturing method appears to induce right bundle branch block and tricuspid valve regurgitation after ventricular septal defect closure more than our alternative technique, shallow suturing just at the edge of the ventricular septal defect (shallower bites at the postero-inferior margin). We aimed to verify our clinical experience of perimembranous ventricular septal defect repair.

Suture tie-down forces and cyclic contractile forces after undersized tricuspid annuloplasty using a Tri-Ad Adams tricuspid annuloplasty ring in an ovine model.

Objectives: This study evaluated suture tie-down forces and cyclic contractile forces (CCFs) after undersized tricuspid annuloplasty using a hybrid band.

Methods: Downsized tricuspid annuloplasty was planned in adult male sheep using 8 force transducers attached from the septal to the anterior annular areas of the ring (segments 1 and 2, flexible septal; segments 3 and 4, semi-rigid posterior; segments 5 and 6, semi-rigid anterior; segments 7 and 8, flexible anterior). CCFs were analysed at 3 different levels of peak right ventricular pressure (RVP): 30, 50 and 70 mmHg.

Ten-year follow-up of dilatation of aortic structures in Fallot-type anomalies.

Tricuspid Valve Repair at Pulmonary Valve Replacement in Repaired Tetralogy of Fallot.

Background: Pulmonary valve replacement (PVR) is often performed in patients with repaired tetralogy of Fallot (TOF). Concomitant tricuspid valvuloplasty (TVP) in those with tricuspid regurgitation (TR) at the time of PVR is still controversial.

Method: We retrospectively reviewed clinical records of patients who underwent PVR between 2001 and 2012.

Pulmonary valve replacement may not restore ventricular volume and functional status in patients with pulmonary regurgitation after late tetralogy of Fallot repair.

Objectives: Clinically, tetralogy of Fallot (TOF) patients who underwent repair late (older than 2 years) appears to have worse outcomes after pulmonary valve replacement than patients who underwent repair early. We proceeded to review the clinical features of late-repaired TOF patients who required pulmonary valve replacement.

Methods: Fifty patients who underwent pulmonary valve replacement after TOF repair over the age of 2 years from 2000 to 2018 were retrospectively reviewed.
