Distrofia muscular de Duchenne, una causa infrecuente de miocardiopatía dilatada / Duchenne muscular dystrophy, a rare cause of dilated cardiomyopathy

Neuromuscular diseases represent a rare cause of dilated myocardiopathy, among them Duchenne muscular dystrophy is the most common. Transthoracic echocardiography and cardiac magnetic resonance imaging can assess cardiac involvement early. The case of a patient diagnosed with Duchenne muscular dystrophy who develops cardiac involvement during cardiology follow-up is presented below.

Una causa olvidada de insuficiencia cardíaca / A forgotten cause of heart failure

Amyloidosis is a low-frequency disease that can cause compromise of different systems. We report a case of heart failure in an 81-year-old woman secondary to amyloidosis, in which the echocardiogram was a valuable diagnostic tool.

Hipertensión arterial en paciente de raza negra: a propósito de un caso / Hypertension in a black patient: a purpose of a case

Hypertension in black patients is usually more frequent and associated with higher morbidity and mortality. Due to demographic changes in the Chilean population, dealing with this group of patients has become more frequent. The case of a young Haitian patient with severe hypertension and target organ damage is presented.

Insuficiencia mitral congénita en el adulto: reporte de un caso y revisión de la literatura / Congenital mitral regurgitation in adults: a case report and literature review

Congenital mitral valve disease is a rare form of mitral regurgitation. The etiological diagnosis is often challenging. The transthoracic echocardiogram is presented as a good initial approach method. The case of a 29-year-old patient referred for the diagnosis of severe congenital mitral regurgitation in parachute is presented. This report aims to illustrate the clinical and echocardiographic presentation of congenital mitral regurgitation.

Mixoma auricular gigante como diagnóstico diferencial de disnea: a propósito de un caso y revisión de la literatura / Giant atrial myxoma as differential diagnosis of dyspnea: a case report and literature review

Cardiac myxomas are the most common benign primary tumors and are most often located in the left atrium at the level of the interatrial septum, with the characteristic of being pedunculated and highly mobile, which is why they sometimes interfere with the functioning of the mitral valve, generating variable degrees of stenosis and mitral insufficiency. Diagnosis is by echocardiography and treatment is surgical resection. We present the case of a patient with a large atrial myxoma and severe double mitral lesion.

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.
