Standard cardiac resynchronization therapy with a second right ventricular lead for severe right ventricular heart failure in 2 patients with repaired tetralogy of Fallot
نویسندگان
چکیده
Although early surgical repair for tetralogy of Fallot (rTOF) has significantly improved clinical outcomes and long-term survival, progressive right ventricle (RV) dysfunction driving morbidity and mortality is often observed in adults with rTOF. Management of RV heart failure is occasionally refractory to even appropriate medical therapies. RV mechanical dyssynchrony that is commonly observed in rTOF patients with right bundle branch block (RBBB) promotes depressed contractility and remodeling, and it is proposed as a desirable therapeutic target. We present 2 cases of rTOF complicated by severe RV heart failure, which were effectively managed with standard cardiac resynchronization therapy (CRT) with a second RV lead (CRT-RV).

Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined dia...

A 65-year-old woman underwent total correction of tetralogy of Fallot with closure of ventricular septal defect, right ventricular outflow patch, pulmonary valve replacement and tricuspid valve repair. Pacemaker implantation using epicardial electrodes was simultaneously needed because she had complete atrioventricular block. The postoperative course was excellent. Eighteen months postoperative...

Background Cardiac MR (CMR) is considered the gold standard to assess right ventricular (RV) function in different scenarios, including cases of congenital heart disease. Moreover, an MR-compatible treadmill coupled with Real Time (RT) CMR has been developed for stress testing, and may be an optimal choice in this setting. The aims of this study were to determine the feasibility and accuracy of...
