BACKGROUND Recent studies have indicated that there are inherent limitations associated with Fontan physiology. However, there have been no quantitative analyses of the effects of right heart bypass on ventricular afterload, hydraulic power, and resultant overall hemodynamics. Methods and Results- During routine cardiac catheterization, aortic impedance and ventricular hydraulic power were dete...

BACKGROUND Fontan is a palliative procedure in patients with single ventricle. Single ventricle supports systemic cardiac output and pulmonary blood flow is passively directed to the right pulmonary artery. Women with Fontan palliation are reported to have increased maternal risk during pregnancy. There are few reports of successful pregnancies in such cases. However data on these pregnancies i...

After a Fontan repair for congenital heart disease, 42 patients underwent graded supine bicycle exercise tests at levels relevant to normal daily activities. Results were compared with those of 28 age-matched normal control subjects. At rest, the cardiac index, stroke index and systolic blood pressure were comparable in both groups, but increases with exercise were smaller in the patients with ...

Sir, In their recent article (1987;57:543-7) on tricuspid atresia with transposition of the great arteries Warnes and Somerville emphasised the inportance of subaortic stenosis in these patients, especially those with coarctation. They suggested that the Fontan procedure was the procedure of choice in these patients but remarked that in patients with subaortic stenosis the prognosis after Fonta...

OBJECTIVE The extracardiac conduit procedure is widely used for patients with heterotaxy syndrome with complex systemic and pulmonary venous anomalies; however, it lacks conduit-growth potential and requires long-term anticoagulation. We present the intracardiac Fontan procedure, which eliminates the above-mentioned disadvantages. PATIENTS AND METHODS Twenty-four patients (mean age, 4.1 years...

OBJECTIVES This study was undertaken to determine the effects of creating a systemic-to-pulmonary venous atrial-level communication (fenestration) at the time of the Fontan procedure on late outcomes. BACKGROUND Fenestrations are frequently performed during Fontan procedures, but late consequences are not well described. METHODS Patient characteristics were compared between those with and w...

the development of ascites in hyperthyroid patients is a rare phenomenon and usually occurs in the context of exaggeration of right-sided heart failure , so it is categorized as high saag ascites. in this case report, we present a 73-year-old man who was referred to us with anorexia, severe weight loss, anemia, lower limbs pitting edema, and also exudative, low saag ascites. extensive work up r...

patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

The Fontan operation is a palliative surgical procedure performed on children, born with congenital heart defects that have yielded only a single functioning ventricle. The total cavo-pulmonary connection (TCPC) is a common variant of the Fontan procedure, where the superior vena cava (SVC) and inferior vena cava (IVC) are routed directly into the pulmonary arteries (PA). Due to the limited pum...

OBJECTIVE The infant with a functional single ventricle (SV) and unobstructed pulmonary blood flow (UPBF) requires early protection of the pulmonary vascular bed to ensure suitability for a subsequent Fontan procedure. Systemic obstruction by aortic arch obstruction, subaortic stenosis, or combination of both, has been widely recognized as an important risk factor for poor outcome in children w...
