Options for ventricular tachycardia ablation after double valve replacement
Case report A 52-year-old man was referred for treatment of recurrent sustained monomorphic VT with variable cycle lengths (CLs) of 360 to 480 ms (125–166 bpm) causing recurrent implantable cardioverter-defibrillator (ICD) shocks despite increasing doses of amiodarone. He had rheumatic heart disease and had undergone mitral and aortic valve replacements with mechanical St. Jude prostheses as we...
متن کاملBundle branch reentrant ventricular tachycardia after transcatheter aortic valve replacement
Introduction Bundle branch reentrant ventricular tachycardia (BBR-VT) is a well-described entity that accounts for 6% of inducible sustained monomorphic VT during electrophysiology studies. BBR-VT is a macroreentrant VT involving the HisPurkinje system and usually requires some form of conduction delay in the His-Purkinje axis. BBR-VT is commonly seen in patients with nonischemic dilated cardio...
متن کاملRight 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...
متن کاملEpicardial Ablation For Ventricular Tachycardia
Epicardial ablation has lately become a necessary tool to approach some ventricular tachycardias in different types of cardiomyopathy. Its diffusion is now limited to a few high volume centers not because of the difficulty of the pericardial puncture but since it requires high competence not only in the VT ablation field but also in knowing and recognizing the possible complications each of whi...
متن کاملCatheter ablation for ventricular tachycardia.
Sustained ventricular tachycardia (VT) is an important cause of morbidity and sudden death in patients with heart disease.1 Implantable cardioverter-defibrillators (ICDs) terminate VT episodes, reducing the risk of sudden death. Recurrent VT develops in 40% to 60% of patients who receive an ICD after an episode of spontaneous sustained VT. A first episode of VT occurs in 20% of patients within ...
