Case Reports
[Echocardiography findings in isolated anomalous origin of the right pulmonary artery from the ascending aorta].
Origin of the right pulmonary artery from the ascending aorta is extremely rare. We describe the echocardiographic findings of this lesion in a single case. The absence of an image of the right pulmonary artery in the echocardiographic short axis view at the level of the great arteries, is highly suggestive of this lesion. Differentiation from truncus arteriosus, aorto-pulmonary window and transposition of the great arteries must, and can be made by a comprehensive echocardiographic study.

Randomized Controlled Trial Clinical Trial
[Modification of thrombocyte function in diagnostic and therapeutic interventions in cardiology].
In patients with coronary heart disease platelet activity may be pathologically increased. Administration of platelet inhibitor drugs is an established treatment principle. The interactions between platelet activation, platelet inhibitor drugs like acetylsalicylic acid (ASA) or molsidomine and the endogenous fibrinolysis were studied in three trials. ⋯ Following successful coronary angioplasty 393 patients were randomized to receive either molsidomine (2 x 8 mg/d) or ASA (1 x 500 mg/d) plus nifedipine (3 x 20 mg/d). Coronary angiography performed after the 6 month treatment period revealed a restenosis rate of 29% in the molsidomine group and of 33% in patients treated with ASA + nifedipine. This difference was not statistically significant.

Randomized Controlled Trial Comparative Study Clinical Trial
[Enoximone in postoperative "low-output syndrome"--comparison with dobutamine].
Low output syndrome sometimes complicates early postoperative states following cardiac surgery. A comparative study of hemodynamic responses to enoximone and dobutamine was carried out in two groups of 20 patients each, during a 22-24 hour postoperative observation period. Enoximone, 1 mg/kg i.v. total dose, was given in the first 20 minutes. ⋯ The enoximone group showed a diminution of systolic arterial pressure of 14% in the first 120 minutes, with a return to initial values after 22 hours. Dobutamine produced an increase in systolic arterial pressure of 23% after 2 hours, maintaining increased values of approximately 20% during the observation period. Heart rate increase slightly in both groups in a similar way.(ABSTRACT TRUNCATED AT 250 WORDS)

The internal mammary artery (IMA) and the right gastroepiploic artery are increasingly used for myocardial revascularization. The postoperative results are much better than those of the saphenous vein regarding mortality, patency rate, and relief of symptoms. The IMA can be used as an in-situ-graft or as a free transplant, either as a single graft or using sequential anastomoses. ⋯ In 74 cases both IMAs were used. In 315 patients sequential anastomoses with one IMA and several coronary arteries were performed. According to our experience, the IMA is an ideal bypass conduit and should be used predominantly.
