Cardiac Magnetic Resonance to Evaluate Complete Substrate Elimination after Endocardial Ventricular Tachycardia Ablation in Chagas Disease

Mauricio I. Scanavacca et al. Rodrigo M. Kulchetscki Carlos E. Rochitte Cristiano F. Pisani

Introduction

The main endpoint of ventricular tachycardia (VT) ablation includes elimination of the abnormal substrate on remapping and rendering non-inducible VT with programmed ventricular stimulation. ^,

Cardiac magnetic resonance (CMR) has been increasingly used as a tool for locating the arrhythmogenic substrate of patients with scar-related VT. The images can be integrated with the electroanatomical mapping to guide ablation to the identified channels responsible for the VT-reentry circuits, optimizing the ablation results. However, until now, CMR has not been used to confirm the complete substrate elimination and effectiveness of VT ablation.

Echocardiography Guiding Percutaneous Treatment of Obstructive Hypertrophic Cardiomyopathy: Navigating (In Known Waters) Is Necessary

Minna Moreira Dias Romano

Obstructive hypertrophic cardiomyopathy (HOCM) is the most common cardiac genetic disease and, besides the risk of malignant arrhythmias, it is responsible for symptoms such as palpitations, syncope, or presyncope, exertional dyspnea, and angina pectoris. Ten percent of patients are refractory to clinical treatment with beta-blockers or calcium channel blockers. Treatment alternatives such as surgical myectomy (SM) or non-invasive methods to reduce left ventricle outflow obstruction may be considered in this population.^,

Although surgical myectomy is considered safe and the procedure of choice in experienced centers, it still has a percentage of post-procedure complications such as tamponade, interventricular septal communication, cerebrovascular accident dissection of coronary arteries, and non-fatal cardiac arrest. Controversy still exists about non-surgical hemodynamic treatment options, and the Heart Team’s expertise is an important factor regarding decisions.
