Extraction of the autoperfused heart-lung block, experimental model.

The technique used by our group for the extraction of the canine autoperfused heart-lung block is described. This was used in 30 dogs, having a success rate of 24 total extractions and function times from 30 minutes to 13 hours." The complications observed were: arterial rupture upon cannulation, aortic rupture upon binding, ventricular fibrillation before completing extraction, and bleeding of the block with subsequent emptying of the reservoir. It is concluded that the technique described is adequate for the extraction of the canine block, although it is still necessary to know better its hemodynamic, biochemical and respiratory behavior.

[Marfan syndrome and echocardiography].

We report the echocardiographic features of nine patients with Marfan syndrome. Six men and three women. Average age: twenty nine years. Sixty six per cent had aneurysmatic enlargement of the aortic root. One hundred per cent of the cases had aortic insufficiency, enlargement of the left ventricular diameter, decrease of the ejection fraction, and decrease in circunferential shortening; mitral prolapse, (in 6) and signs of high pulmonary artery pressure (in 4 cases). Hemodynamic studies performed in 46 per cent of the patients correlated well with the echocardiographic features. Autopsy performed in the patients who died, corroborated the cardiovascular abnormalities. We conclude that the use of the echocardiogram is a useful non-invasive technique for the early evaluation of the cardiovascular features in the Marfan syndrome.
