Article Synopsis
- * Researchers conducted a multi-institutional retrospective study, analyzing data from 1,117 post-Fontan patients and identifying key risk factors such as high central venous pressure (CVP) and severe atrioventricular valve regurgitation.
- * Findings indicate that patients exhibiting high CVP and/or severe valve problems approximately one year post-surgery are at higher risk for severe liver disease, suggesting a need for further investigation into whether reducing these factors could lower disease incidence. *
Objectives: To achieve the growth of right-sided heart structures, our choice of the first palliation for patients with pulmonary atresia and intact ventricular septum (PA-IVS) includes a modified Blalock-Taussig shunt (BTS) with pulmonary valvotomy. We sought to analyse the impact of the first palliation on the growth of right-sided heart structures and factors associated with a choice of definitive surgical procedure.
Methods: Fifty patients with PA-IVS who underwent a staged surgical approach from 1991 to 2012 were retrospectively reviewed.
Objective: The Damus-Kaye-Stansel operation sometimes results in deteriorating semilunar valve insufficiency. We verified the semilunar valve function after the Damus-Kaye-Stansel operation and compared the end-to-side Damus-Kaye-Stansel with the double-barrel Damus-Kaye-Stansel.
Methods: Forty-seven patients who underwent the Damus-Kaye-Stansel operation between June 1993 and August 2008 were retrospectively reviewed.
Objective: A lateral tunnel-total cavopulmonary connection (LT-TCPC) using a right atrial (RA) free wall is the first choice of treatment for patients with a small body weight in this institute. Whether the growth of the LT is appropriate or not according to the growth of the body remains controversial. In addition, the optimal initial diameter of an LT is unknown.

A total of 43 patients with TGA/VSD or DORV who underwent an original Rastelli-type operation in this institute between March 1993 and January 2009 were reviewed retrospectively. These patients were divided into two groups using the length between the top of the interventricular septum and the aortic valve (IVS-AV length); Group A; IVS-AV length <80% of normal left ventricular end-diastolic diameter (LVDd).

- The study analyzed the outcomes of 29 patients with impaired ventricular function who underwent the Fontan operation between 1991 and 2007, focusing on the impact of their condition on mortality and morbidity.
- The research found that, despite the high-risk status of these patients, there were no early deaths, and while late complications included two fatalities and re-operations, significant improvements in heart function and oxygen saturation were observed over time.
- At a median follow-up of 7.5 years, the patients maintained a stable ejection fraction and showed reductions in abnormal ventricular volume, although some experienced issues like congestive heart failure, arrhythmias, and protein-losing enteropathy.
We diagnosed hypoplastic left heart syndrome in a 26-week-old fetus using fetal echocardiography. Color Doppler ultrasonography was helpful for evaluating the structural abnormalities. The diameters of the aorta and the pulmonary artery were measured periodically from 26 to 38 weeks of gestation.
