BACKGROUND: At our institution, we perform bilateral pulmonary artery banding (BPAB) as the first-stage palliation for interrupted aortic arch (IAA) with low birth weight or severe subaortic stenosis (SAS). The present study aimed to identify factors that may influence the decision regarding the type of second-stage operation, that is, univentricular palliation or biventricular repair, in these patients. METHODS: Cardiac catheterization and angiographic data of nine patients with IAA who underwent initial BPAB and subsequent univentricular or biventricular repair were retrospectively analyzed...

BACKGROUND: Mechanical circulatory support (MCS) of a failing Fontan circulation remains challenging. We hypothesized that MCS can be provided by converting the Fontan circulation into a mechanically assisted single ventricle parallel circulation (MASVC). METHODS: A porcine model of functionally univentricular circulation was created under cardiopulmonary bypass (CPB) by performing an atrial septectomy, tricuspid valvectomy, and interrupting antegrade pulmonary blood flow...

OBJECTIVES: The Fontan procedure [total cavopulmonary connection (TCPC)] is the final palliation for patients with univentricular physiology. We studied differential perfusion ratio and percentage uptake of a radiotracer in different zones of each lung following TCPC. METHODS: Between July 2015 and June 2017, 45 patients underwent 99mTc macroaggregated albumin lung perfusion scan at a mean follow-up period of 49.3 ± SD 26.1 days following TCPC. Differential perfusion ratio and percentage uptake of the radiotracer in the upper, middle and lower zones of each lung were calculated...

We present a 22-year-old patient with a univentricular heart who had already undergone five open heart surgeries including a Damus-Kaye-Stansel procedure, Fontan completion and tricuspid valve replacement. In addition, epimyocardial pacemaker implantation and repeated revisions had been necessary. He developed symptomatic free regurgitation of the pulmonary portion of his DKS anastomosis. To avoid additional high-risk open-heart surgery, we successfully implanted an Edwards Sapien 3 valve transfemorally in the pulmonary portion of the DKS anastomosis relieving insufficiency...

BACKGROUND: Previous studies have suggested the presence of dyssynchrony in the functionally single ventricle. The aim of this study was to investigate the presence of classic-pattern dyssynchrony (CPD), characterized by typical early and late deformation of opposite walls, and its relation to QRS duration and myocardial function in patients with single-ventricle physiology after Fontan palliation. METHODS: In a retrospective cross-sectional study, 101 adolescent and adult patients with single-ventricle physiology after the Fontan procedure were investigated...

OBJECTIVES: Neonates with congenital heart disease may have an increased risk of cerebral sinovenous thrombosis, but incidence rates are lacking. This study describes the clinical and neuroimaging characteristics of cerebral sinovenous thrombosis in neonates undergoing cardiac surgery. METHODS: Forty neonates (78% male) requiring neonatal univentricular or biventricular cardiac repair using cardiopulmonary bypass were included. All underwent preoperative (median postnatal day 7) and postoperative (median postoperative day 7) magnetic resonance imaging of the brain, including venography, to detect cerebral sinovenous thrombosis...

Total anomalous pulmonary venous drainage (TAPVD) is an uncommon cardiac defect in children. The mixed subset accounts for 5%-10% of the TAPVD and is variable in its anatomy. The outcomes associated with this subset of patients are rarely reported. A retrospective review of all patients with mixed TAPVD undergoing repair at a single institution (1984-2014) was conducted. A descriptive analysis was performed. Twenty-four patients underwent repair for mixed TAPVD (6 univentricular physiology, 18 biventricular physiology)...

Circulatory assistance is developing as a treatment for patients with end-stage heart failure. There are two alternative devices: a univentricular circulatory assist pump, or a total artificial heart. It is used to bridge the time to transplantation and, increasingly, as a definitive alternative to a heart transplant.

Infants born with univentricular heart disease undergo Fontan surgery in order to establish separate systemic and pulmonary circulations. This surgery results in better blood circulation across a single ventricle that supplies oxygenated blood to the body and passively returns venous blood to the lungs through the total cavopulmonary connection (TCPC). Reducing the pressure drop across the TCPC during Fontan circulation helps in reducing the work load of univentricular heart and various designs have been proposed for this purpose...

Although 85% of patients with univentricular heart after Fontan procedure survive twenty years after operation, the procedure alone seems to be an inadequate treatment as a permanent clinical solution. Patients with a "Fontan physiology" additionally have to face a various extra-cardiac complications, including thyroid, liver and kidney dysfunction, which are not only potentially life-threatening, but also can potentiate the circulatory insufficiency. AIM: The aim of the study was to assess a multiorgan dysfunction in adult patients after Fontan operation in long term follow-up and compare to healthy controls...
