Surgical Maze Procedures for Atrial Arrhythmias in Univentricular Hearts, from Maze History to Conversion–Fontan
In general, symptoms of atrial fibrillation are an indication for intervention, the most important being the elevated risk for thrombo-embolism. While pharmaco-medical treatment for atrial fibrillation is aimed at either rate or rhythm control (van Gelder et al., 2002), invasive treatment for atrial fibrillation is aimed at rhythm control. An invasive approach may consist of percutaneous cathet...
متن کاملChanges in venous return parameters associated with univentricular Fontan circulations.
To clarify the physiology of venous return (Q(vr)) in Fontan circulations, venous return conductance (G(vr)) and mean circulatory filling pressure (P(mcf)) were determined in pentobarbital sodium-anesthetized pigs. Relationships between Q(vr) and right (biventricular, n = 8) or left (Fontan, n = 8) filling pressures are described by straight lines with significant correlation coefficients. Esti...
متن کاملFontan conversion with arrhythmia surgery.
OBJECTIVE Hemodynamic abnormalities and refractory atrial arrhythmias in patients late after the Fontan operation result in significant morbidity and mortality. We reviewed our experience with Fontan conversion and concomitant arrhythmia surgery. METHODS Between January 1996 and February 2004, 16 patients underwent Fontan conversion and arrhythmia surgery. Mean age at the initial Fontan opera...
متن کاملCardiovascular adaptation to the Fontan circulation.
Although medium-term survival following Fontan operations in the modern era has improved dramatically, late cardiovascular and extracardiac morbidity are common and are associated with impaired quality of life and premature late mortality. This serves as a reminder of the extraordinary adaptations required of the cardiovascular system when the systemic arterial, systemic venous and pulmonary ci...
متن کاملIs the extracardiac conduit the preferred Fontan approach for patients with univentricular hearts? The extracardiac conduit is the preferred Fontan approach for patients with univentricular hearts.
Fontan palliation for single-ventricle patients was first described in 1971.1 The original approach was in the form of a classic atriopulmonary Fontan connection, bypassing the nonfunctional right ventricle. After recognizing the long-term complication of an atriopulmonary connection (right atrial dilation, arrhythmias, and thrombus formation), modifications have been made. The atriopulmonary c...
