Catheter ablation of atrial flutter in an adult with a univentricular heart, common atrium, and single atrioventricular valve: a case report-'complex things don't always require a complex solution'.

Cardiac Electrophysiology, National Medical Center 'November 20th', ISSSTE, Av. Felix Cuevas #540, Col. Del Valle Del. Benito Juarez, C.P. 03100 Mexico City, Mexico.
Background: The 'univentricular' heart encompasses a variety of congenital cardiac defects characterized by a single functional ventricle and an underdeveloped ventricular chamber. Surgical intervention, typically in infancy or childhood, aims to regulate pulmonary blood flow volume. In adulthood, untreated patients may experience limitations in physical activity and elevated morbidity due to persistent cyanosis and arrhythmias, notably after the Fontan procedure.

Objective: The modified Fontan operation, a palliative approach for single ventricular circulation patients, often incorporates a fenestration to facilitate postoperative management. Postoperative fenestration closure is sometimes performed to mitigate potential risks such as low oxygen saturation. However, the benefits and potential risks of this procedure remain under investigation.

Department of Cardiovascular Surgery, Nagano Children's Hospital, Azumino, Japan.
Background: The discussion of Fontan fenestration is difficult because many institutions have different strategies over time. In our institute, we performed a non-fenestrated Fontan procedure for single-ventricular physiology as our definitive strategy.
Methods: Between August 1999 and December 2007, 72 consecutive patients with single-ventricle physiology underwent extracardiac total cavopulmonary connection without fenestration as our definitive strategy.
Modified Damus-Kaye-Stansel Anastomosis to Prevent Coronary Obstruction Between the Great Arteries.

Department of Pediatric Cardiovascular Surgery, Children's Medical Center, Kyoto Prefectural University of Medicine, Kyoto, Japan.
The conventional Damus-Kaye-Stansel procedure may cause coronary artery compression when the coronary arteries are situated between the great arteries. We have performed a modified Damus-Kaye-Stansel procedure utilizing a "flap-bridging technique," in which an inverted U-shaped flap incised from the aorta is bridged to the main pulmonary trunk, creating sufficient space between the great arteries, in an 8-month-old boy who was a Fontan candidate with congenitally corrected transposition of the great arteries. This modified approach yielded favorable outcomes without coronary events and can effectively prevent coronary obstruction in cases where the coronary arteries run between the great arteries.

Ann Thorac Surg Short Rep
September 2024
Biostatistics Unit, Department of Data Science, National Center for Child Health and Development, Tokyo, Japan.
Background: The primary treatment for hypoplastic left heart syndrome (HLHS) is the Fontan pathway, which entails performing the Glenn procedure. We hypothesized that the superior vena cava in patients with HLHS was short. As the length of the superior vena cava influences the Glenn procedure, we compared its length between patients with HLHS and those with other congenital heart diseases.
