Background: Fenestrated total cavopulmonary connection has gained popularity due to its capacity to reduce systemic venous pressure and enhance cardiac output. However, there is ongoing debate about the immediate and long-term advantages of fenestration in this context.
Method: A retrospective cohort study was conducted involving 97 patients who underwent extracardiac total cavopulmonary connection at Chiang Mai University Hospital between January 1999 and December 2019. The patients were initially categorized into two groups: fenestrated ( = 71) and nonfenestrated ( = 26). After exclusion and reassignment, the long-term outcomes were analyzed for the fenestrated ( = 68) and nonfenestrated ( = 25) groups. To address potential confounding factors between the two groups, propensity scores were computed using logistic regression analysis.
Results: The study found no significant differences in preoperative and operative data. Immediate postoperative outcomes showed no significant variations in major complications, intensive care unit stay, oxygen saturation, and posttotal cavopulmonary connection pressure. In the long-term assessment, the fenestrated group demonstrated significantly lower rates of mortality, protein-losing enteropathy, liver mass, and cirrhosis. However, after employing a multilevel model stratified by propensity score analysis, only long-term mortality rate was significantly lower in the fenestrated group (hazard ratio = 0.12, 95% confidence interval = 0.02-0.97). Fenestration patency closed gradually through spontaneous closure and device intervention.
Conclusion: The study found no major differences in immediate postoperative outcomes. In the fenestrated cohort, significantly lower incidences of protein-losing enteropathy, liver mass, cirrhosis, and long-term mortality were observed. However, multilevel model stratified by propensity score analysis indicated that only the lower long-term mortality demonstrated a major effect.

Background: Fontan circulation maintains an elevated venous pressure; this promotes venous and lymphatic congestion and may lead to late circuit failure. Our objective was to determine the association between thoracic lymphatic perfusion patterns assessed by magnetic resonance imaging and late Fontan failure.
Methodology: A retrospective study was performed.

Objectives: There is dearth of data on long-term outcomes of systemic semilunar (SS) or atrioventricular (AV) valve operation in adult patients with a Fontan circulation. We describe a single-centre experience of adults who underwent valve surgery late after a Fontan procedure.
Methods: We retrospectively reviewed all patients with a Fontan circulation who had a reoperation for severe valve disease during adulthood in our centre.

Recent research in patients with functionally univentricular hearts (UVH) is focusing on pathologies of the lymphatic vessels. Morphology of the abdominal lymphatic vessels was analyzed by MRI in patients with UVH following total cavopulmonary connection (TCPC) and it was examined, if clinical and laboratory parameters correlate with changes after TCPC. We prospectively examined 33 patients at the age of 19.

Objectives: This study aims to identify the causes of failure in Fontan patients with a total cavopulmonary connection.
Methods: We conducted a comprehensive review of all patients who underwent a total cavopulmonary connection procedure at our centre between 1988 and 2023, aiming to identify and analyse the factors contributing to Fontan failure (defined as mortality, heart transplantation, Fontan takedown, protein-losing enteropathy, plastic bronchitis or New York Heart Association Functional Classification class III or IV).
Results: The study included 217 patients (median age at time of Fontan completion 3.
