Background: The use of Cardiovascular Implantable Electronic Devices (CIED), such as the Implantable Cardioverter Defibrillator (ICD) and Cardiac Resynchronization Therapy (CRT), is increasing. The number of leads may vary according to the device. Lead placement in the left ventricle increases surgical time and may be associated with greater morbidity after hospital discharge, an event that is often confused with the underlying disease severity. Objective: To evaluate the rate of unscheduled emergency hospitalizations and death after implantable device surgery stratified by […]

Abstract Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) was initially recognized as a clinical entity by Fontaine and Marcus, who evaluated a group of patients with ventricular tachyarrhythmia from a structurally impaired right ventricle (RV). Since then, there have been significant advances in the understanding of the pathophysiology, manifestation and clinical progression, and prognosis of the pathology. The identification of genetic mutations impairing cardiac desmosomes led to the inclusion of this entity in the classification of cardiomyopathies. Classically, ARVC/D is an inherited […]

Clinical aspects The patient had syncope episodes since the age of 20 years, and heart failure since the age of 30 years, undergoing cardiac transplantation at the age of 36 years. Since symptom onset, heart disease with marked left ventricular dilatation and moderate dysfunction was detected. The exercise test revealed frequent ventricular arrhythmia. His syncope episodes were attributed to malignant ventricular arrhythmias, and a cardioverter defibrillator was implanted. […]

The study by Silva et al. presented the results of a series of cases from a single-center registry of implantable cardiac devices, including 28 implantations of isolated cardioverter defibrillators (ICD) and 14 associated to resynchronization (CRT-ICD), in addition to procedures for generator replacement and handling of electrode cable. ICD and CRT-ICD implantations were considered the strongest predictors of re-admission into the hospital during a six-month period after the surgical procedure, although it is not clear whether there was adjustment by […]
