Abstract
Chagas disease (CD), with approximately 10,000 deaths annually, has become a worldwide health problem. Approximately 35% of cases may show cardiac manifestations such as arrhythmias and/or conduction disorders, heart failure, thromboembolic accidents, and sudden death. The Amazon region has long been considered a non-endemic area for CD; however, in the last decades, with an increase in the number of acute and chronic cases, disease evolution has received greater attention. Here, we report the successful implementation of a cardioverter-defibrillator for the prevention of sudden death in a patient with autochthonous Chagas cardiomyopathy in the Brazilian Amazon.

We report the successful implementation of a cardioverter–defibrillator for the prevention of sudden death in a patient with autochthonous Chagas cardiomyopathy in the Brazilian Amazon
Previous studies suggest lower morbidity levels related to CD in the Amazon region, probably due to the presence of different T. cruzi strains from those found in traditionally endemic areas[3,4]
Summary
Chagas disease (CD) is endemic in Latin America and has become a worldwide public health problem due to the increase in human migration. We present a case report of successful cardioverterdefibrillator implantation for the prevention of sudden death in a patient with autochthonous CCM in the Brazilian Amazon. A 60-year-old man, a painter currently living in the state capital, Manaus but born in Autazes in the interior of Amazonas, where he lived until the age of 18, was diagnosed with Chagas disease in 2015 after an attempt to donate blood He developed the cardiac form of the disease and presented with dilated cardiomyopathy with ventricular dysfunction. Monomorphic ventricular tachycardia without pulse was monitored and recorded on the ECG (Figure 2A), which showed cardiopulmonary arrest. Three months after ICD implantation, the patient presented with an ICD shock episode, documented by intracavitary electrogram during telemetric evaluation (Figure 2B and 2C)
