Muerte Súbita Post Infarto: ¿Cuándo Implantar un Desfibrilador Automático? Breve revisión a propósito de un caso / Sudden Death After Infarction: when To Implant An Automatic Defibrillator? Brief review about a case

Sudden death is the most serious complication of acute coronary syndromes. The highest percentage occurs at home with a very low survival rate. The highest risk group are patients with ejection fraction under 40% after an acute myocardial infarction. So far the indication of the clinical practice guides are the implantation of ICD as a secondary prevention, and as a primary prevention when the systolic function is severely diminished, however there is an interval of 40 days in which the implant has not managed to demonstrate benefits. In this critical period patients should be managed with beta-blockers. So far, the absolute benefit of using portable cardioverter-defibrillators as a prophylactic bridge to the ICD implant has not been demonstrated. The following revision is based on the most relevant clinical practice guides in the field carried out in relation to a clinical case

Persistencia de conducto arterioso en adulto: a propósito de un caso / Persistence of the duct arteriosus in adults: a propos of a case

Congenital heart disease includes a wide range of heart defects that appear at birth, corresponding to the most frequent group of genetic alterations. They represent the most frequent birth defects in the world, affecting millions of newborns annually. Chile is not exempt from this public health problem, estimating a prevalence of 8-10 per 1,000 live births, similar to international figures. Some of these defects are not diagnosed in a timely manner due to various causes, including causes such as poor clinical translation and limited accessibility to the Public Health system. Thanks to the improvement of technological resources, more cases of congenital heart disease are diagnosed every day and the time of diagnosis is getting earlier. The case presented below refers to a 47-year-old male patient with several comorbidities, who underwent a Doppler echocardiogram during his hospitalization due to acute respiratory failure, where a systodiastolic flow was detected in one of the compatible pulmonary arteries, with a patent ductus arteriosus.
