Purpose: To analyze the response of hypercholesterolemic elderly patients to pravastatin.

Methods: Two hundred and sixty six primary hypercholesterolemics, 65 to 80 years of age, after ingesting a standard diet for four weeks, received 10mg of pravastatin for 12 weeks.

Results: Average reductions of 24% or more were observed for TC and LDL-C, and more than 60% of those reductions were considered good or excellent (above 20%).

[Transposition of the great arteries with posterior aorta].

Two cases of transposition of the great arteries (TGA) with posterior aorta are reported. The first was submitted to the Senning procedure with good outcome; the other had the diagnosis of double outlet right ventricle with severe pulmonary stenosis, and a Blalock-Taussig shunt was accomplished for hypoxic crisis. The patient died 11 days after surgery and the necropsy demonstrated TGA with posterior aorta.

[Randomized study comparing mitral valve replacement with and without preservation of mitral ring chordae tendinae papillary continuity].

Purpose: To demonstrate the importance of the preservation of mitral annulus-chordae tendineae-papillary muscles continuity in mitral valve replacement.

Methods: We studied 21 patients who were submitted to mitral valve replacement, divided in two randomized groups: group 1, 12 cases who undergone mitral valve replacement, with preservation of the posterior leaflet and correspondent chordae tendineae; and group 2-9 cases who undergone conventional mitral valve replacement, excising the mitral valve apparatus. The left ventricular function was studied both, in the pre and post operative period, by echocardiography, cardiac catheterization, and radioisotopic study.

Ischemic cardiomyopathy in childhood is related with congenital and acquired pathologies which could lead to serious cardiac sequelae as myocardial infarction and sudden death. Unfortunately, when coronary artery malformations are excluded, it is difficult in some cases to be completely certain on the etiology of the arterial coronary disease, due the lack of pathognomonic diagnostic tests. Case report of 6 year old child, with severe coronary artery disease: aneurysm of main branch of left coronary artery; left anterior descending branch and right coronary artery occlusions with accentuated myocardial dysfunction.
