[Right hemitruncus in adulthood: an unusual finding].

Hemitruncus arteriosus is a rare congenital heart disease characterized by the abnormal origin of one of the branches of the pulmonary artery from the ascending aorta. In most cases, its diagnosis is made during childhood; in addition, due to its high morbidity and mortality, its asymptomatic evolution and survival to adulthood is extremely unusual. We present the case of a 30-year-old male patient, with a history of surgical closure of patent ductus arteriosus during childhood, who was asymptomatic until a year ago, in whom hemitruncus arteriosus was diagnosed after recurrent episodes of hemoptysis.

[Clinical profile and therapeutic strategies in patients with arrhythmogenic cardiomyopathy treated in a national reference institute].

Objective: To determine the epidemiological, clinical, electrocardiographic, imaging characteristics and main therapeutic strategies performed in patients with arrhythmogenic cardiomyopathy treated in a national reference cardiovascular institute.

Materials And Methods: Observational, descriptive and retrospective study that attempts to identify the clinical characteristics, complementary tests and therapeutic strategies performed in patients with arrhythmogenic cardiomyopathy treated at the Instituto Nacional Cardiovascular - INCOR EsSalud in Lima, Peru.

[Cardiac Tamponade due to Rupture of a Giant Coronary Aneurysm over Coronary Fistulas: Report of an Unusual Case].

Coronary artery fistulas are rare clinical entities and their association with giant coronary aneurysms is even more unusual. Most fistulas are asymptomatic, but aneurysms could develop symptoms depending on their diameter. We present a patient with chest pain and cardiac arrest, who later developed cardiac tamponade that needed emergency surgery, due to rupture of a giant coronary aneurysm developed from confluent coronary artery fistulas from two coronary arteries to pulmonary artery.
