[Pericardial constriction with predominant involvement of the left heart chambers]. / Constricción pericárdica con repercusión predominante sobre cavidades cardíacas izquierdas.

Constrictive pericarditis is a common complication of purulent pericarditis and it can evolve to hemodynamic patterns different from the classical one. We report a patient that after purulent pericarditis, his clinical and hemodynamic features suggest isolated constriction of the left ventricle.

[Acute myocardial infarct and Friedreich's disease]. / Infarto agudo de miocardio y enfermedad de Friedreich.

The association between Friedreich's ataxia and heart disease is well known. Microvascular disease and spasm of coronary arteries have been reported. We report now a patient with the association between this disease and acute myocardial infarction, which raises the hypothesis that it may be related with the already known cardiac abnormalities in this disease.
