Successful percutaneous epicardial catheter ablation of ventricular tachycardia arising from the crux of the heart in a patient with prior coronary artery bypass grafting☆

چکیده
A 63-year-old man with a history of remote inferior myocardial infarction and coronary artery bypass grafting (CABG) underwent catheter ablation of ventricular tachycardia (VT). Epicardial catheter ablation of the VT was successful at the crux of the heart despite limited mapping within the pericardial space due to pericardial adhesion. Percutaneous subxiphoidal pericardial approach is usually impossible in patients with a history of open heart surgery due to pericardial adhesions. This report suggested that epicardial VT arising from the crux of the heart could be successfully treated by catheter ablation via subxiphoidal pericardial approach despite pericardial adhesions complicated by prior CABG.

Percutaneous epicardial access for mapping and ablation is feasible in patients with prior cardiac surgery, including coronary bypass surgery.
BACKGROUND Prior cardiac surgery, especially the presence of coronary artery bypass grafts, is thought to preclude percutaneous epicardial access (EpiAcc) and, therefore, mapping and ablation. We evaluated the feasibility and safety of EpiAcc in patients with a prior cardiac operation. METHODS AND RESULTS We retrospectively analyzed all patients who underwent EpiAcc for ablation for ventricul...

Certain subsets of high-risk mitral valve patients are not suitable candidates for transcatheter therapies. The objective of this report is to present a young patient with combined mitral valve and coronary artery disease to illustrate these challenges.In this report, we present a 47-year-old man with longstanding HIV infection who was referred with severe mitral regurgitation (MR) and profound...
متن کاملEpicardial access and ventricular tachycardia ablation in a postmyocarditis patient using a nonfluoroscopic catheter visualization system
Introduction The efficacy of catheter ablation for scar-related ventricular tachycardia (VT) has significantly improved since the introduction of percutaneous epicardial access by Sosa in 1996. Percutaneous epicardial ablation has been used in approximately 30% of VT ablation cases associated with nonischemic cardiomyopathy. However, complications such as cardiac tamponade, coronary artery lace...
متن کاملEffect of coronary artery bypass on QT dispersion
Introduction: QT dispersion (QT Max – QT min) reflects inhomogeneous ventricular depolarization that may provide a substrate for serious arrythmias and is associated with adverse clinical outcomes in patients with coronary artery disease. Some studies have shown reduction in QT dispersion after successful angioplasty due to coronary reperfusion, but effect of coronary artery bypass grafting o...
متن کامل[Percutaneous epicardial radiofrequency ablation of idiopathic ventricular tachycardia].
We describe 3 patients with ventricular tachycardia in whom epicardial ablation was done after prior attempts of endocardial ablation had failed. Clinical ventricular tachycardia originated at the right ventricular outflow tract in one patient and near the mitral annulus in another patient. In these two cases ventricular tachycardia was mapped and successfully ablated with a percutaneous subxip...
