[Massive tricuspid valve insufficiency after blunt chest trauma: report of one case].

Cardiac valve lesions after a blunt chest trauma are rare and less than 1% of cardiac lesions because of chest trauma affect the tricuspid valve. We report a 70 year-old female that suffered a severe chest trauma in a car accident. During the repair of the multiple skeletal lesions, the patient had a severe hemodynamic decompensation.

[Fighting the coronary artery disease epidemic in Chile: caveats in the control of cardiovascular risk factors].

In this issue of the journal Lanas et al report an estimation of population attributable risk (PAR) for myocardial infarction (MI) derived from different risk factors in Chile. Cigarette smoking, dyslipidemia and hypertension accounted for 71% of total PAR. Mortality from MI has decreased in Chile, but epidemiologic surveys carried out in different hospitals across the country, strongly support that most of this effect comes from better treatment of MI.

[Partial or total replacement of the aortic arch. Experience in 23 patients].

Background: Surgery of the aortic arch is a very complex procedure since it requires protective strategies for the brain, heart and rest of the body.

Aim: To communicate our experience in the first 23 total or partial replacements of aortic arch.

Material And Methods: Retrospective search in the database of the Cardiovascular Surgery Unit for patients subjected to partial or total replacement of the aortic arch since 1998.
