Technological advances during recent years and developments in anaesthesiology and intensive care have increased the interest in capnometry (measuring the CO2 content in the respiratory air). The physiological background and the principles of the method are presented. The applicability in clinical work and the limits of the method are presented and discussed.
A 32-year-old male patient with clinical and electrocardiographic evidence of acute myocardial infarction underwent coronary angiographic study. We observed nonocclusive thrombosis simultaneously in right and left anterior descending coronary arteries, without confirmation of spasm or obstructive artery disease in other coronary branches. Documentation of coronary thrombosis in more than one artery is rare, and its pathophysiology is still unknown. With the advent of thrombolytic therapy and immediate coronary angiographic studies in patients with evolving myocardial infarction, it has been possible to confirm the presence of thrombus and the type of coronary disease. In this case, we observed total lysis of both thrombi and the final aspect of "normal" angiographically reperfused coronary arteries.
PURPOSE: To evaluate the evolution of patients with critical aortic stenosis (AS) submitted to balloon aortic valvuloplasty (BAV). PATIENTS AND METHODS: sixteen patients (mean age 74.0 +/- 5.1 years), 11 (68.7%) women. The study periods consisted during the 3 rd (post-1) and 15th month (post-2) after dilatation. RESULTS: The functional class of angina and dyspnea persisted in all patients during period post-1, in 75% of the patients, during period post-2 in relation to intra-hospital evaluation. However, in period post-1, 53% of the patients had significant reduction of aortic valve area, trend which remained in period post-2. Simultaneously, progressive (insignificant) elevation of the left ventricular aortic peak to peak gradient was noticed in the periods post-1 and post-2. Two deaths and two aortic valve replacements occurred during the study. CONCLUSION: BAV is associated to maintenance of functional class improvement obtained immediately after dilatation despite the aortic valve restenosis registered by echodopplercardiography.
