PURPOSE: Children with congenital heart diseases (CHDs) may need to be followed up with contrast-enhanced CT following the Fontan operation because complications such as the occlusion of conduits may occur. The purpose of the present study was to develop an adequate contrast-enhanced CT protocol for children with CHD following the Fontan operation. MATERIALS AND METHODS: Between July 2012 and July 2017, 29 CT examinations for 26 patients aged 2-11 years (median 5 years) with CHD following the Fontan operation were performed using dual-source CT...

Congenitally corrected transposition of the great arteries (ccTGA) can occur in isolation, or in combination with other structural cardiac anomalies, most commonly ventricular septal defect, pulmonary stenosis and tricuspid valve disease. Clinical recognition can be challenging, so echocardiography is often the means by which definitive diagnosis is made. The tricuspid valve and right ventricle are on the systemic arterial side of the ccTGA circulation, and are therefore subject to progressive functional deterioration...

BACKGROUND: The Fontan operation (FO) has evolved and many centers have demonstrated improved results relative to those from earlier eras. We report a single-institution experience over three decades, describing the outcomes and evaluating risk factors. METHODS: Successive patients undergoing primary FO were divided into era I (1984-1994), era II (1995-2004), and era III (2005-2014). Clinical and operative notes were reviewed for demographic, anatomic, and procedure details...

Computational fluid dynamics (CFD) is a modeling technique that enables calculation of the behavior of fluid flows in complex geometries. In cardiovascular medicine, CFD methods are being used to calculate patient-specific hemodynamics for a variety of applications, such as disease research, noninvasive diagnostics, medical device evaluation, and surgical planning. This paper provides a concise overview of the methods to perform patient-specific computational analyses using clinical data, followed by a case study where CFD-supported surgical planning is presented in a patient with Fontan circulation complicated by unilateral pulmonary arteriovenous malformations...

We tested our hypotheses that central venous pressure (CVP) shows an excessive increase in response to volume overload in Fontan circulation according to the extent of the reduction in venous capacitance (Cv), and that the maximum CVP after volume loading is associated with hepatic congestion. Changes in CVP after angiography (volume loading) were examined in 40 patients with Fontan circulation and 29 controls with biventricular circulation. CVP significantly increased with angiography in both groups, but the changes were much more evident in the Fontan group than in controls (3...

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...

In cardiac physiology, single ventricle typically refers to the presence of a dominant systemic ventricle along with a hypoplastic ventricle. The Fontan operation is used to repair the single ventricle by directing deoxygenated systemic venous flow to the pulmonary arterial circulation. Normal pregnancy physiology, particularly increased intravascular volume, increased heart rate, increased cardiac output, hypercoagulability and decreased systemic vascular resistance, can exacerbate cardiac disease in patients with Fontan circulation, leading to pregnancy complications...

Complex cardiac anomalies are sometimes channeled toward Fontan palliation for various reasons. Nevertheless, anatomical repair after bidirectional cavopulmonary shunt may be another option with theoretical benefits. In this study, we report our experience with anatomical repair conversion in challenging patients who had been palliated with bidirectional cavopulmonary shunt. Retrospective review was conducted in patients who underwent anatomical repair conversion from prior bidirectional cavopulmonary shunt palliation between January 2008 and March 2016...

BACKGROUND: Optimal pulmonary perfusion is crucial for a well-functioning Fontan circulation in patients with hypoplastic left heart syndrome (HLHS). To obtain an adequate size of the left pulmonary artery (LPA), patch enlargement is a routine part of Hemi-Fontan procedure in our center. However, LPA patch enlargement at the time of the modified Norwood procedure may have surgical advantages. Therefore, the aim of this study was to evaluate if anatomical and functional effects of the new approach are superior...

The Fontan procedure was first performed in the seventies as a palliation for patients with single ventricle physiology. A feared complication after a Fontan procedure is the development of protein losing enteropathy (PLE). Systemic inflammation has a negative effect on the intestinal barrier integrity, which has supported the use of steroids in this setting. To the best of our knowledge there are no studies linking intestinal inflammation in patients with PLE after Fontan. The objective of this study was to identify the presence of intestinal inflammation measured by FC in patients with PLE after a Fontan procedure...

This work presents a new extraction material, namely, Q-100, based on hypercrosslinked magnetic particles, which was tested in dispersive solid-phase extraction for a group of sweeteners from environmental samples. The hypercrosslinked Q-100 magnetic particles had the advantage of suitable pore size distribution and high surface area, and showed good retention behavior towards sweeteners. Different dispersive solid-phase extraction parameters such as amount of magnetic particles or extraction time were optimized...

BACKGROUND: Little is known about the relationship between brain volumes and neurodevelopmental outcome at two years of age in children with single ventricle congenital heart disease (CHD). We hypothesized that reduced brain volumes may be associated with adverse neurodevelopmental outcome. METHODS: Volumetric segmentation of cerebral MRI scans was done in 44 patients without genetic comorbidities and in eight controls. Neurodevelopmental outcome was assessed with the Bayley-III scales...

Allergy to contrast media is hazardous in patients who need multiple cardiac catheterizations. We describe the case of a 16-year-old boy who presented with fatigue and cyanosis. He had undergone a Fontan operation 14 years previously, after which he developed an allergy to iodinated contrast media. Contrast echocardiograms by manual injection of microbubbles suggested the presence of a venovenous collateral vessel from the brachiocephalic vein draining into the pulmonary vein. We used intravascular ultrasound as the sole imaging method to identify the target vessel and to guide deployment of an Amplatzer Vascular Plug II...

Advances in surgical techniques have led to the survival of most patients with congenital heart disease (CHD) up to their adulthood. During their lifetime, many of them develop atrial tachyarrhythmias due to atrial dilatation and scarring from surgical procedures. More complex defects and palliative repairs are linked to a higher incidence and earlier occurrence of arrhythmias. Atrial fibrillation (AF) is common in patients who have atrial septal defects repaired after age 55 and in patients with tetralogy of Fallot repaired after age 45...
