[Bedside cardiac catheterization. Advantages and disadvantages].
Three hundred patients submitted to bedside heart catheterization (BHC) from 1973 to 1985 were studied, in order to assess advantages and risks of the procedure. Two-hundred and sixty seven patients (89%) suffered a myocardial infarction (MI) and 146 of them were in functional class (Killip) II, 36 in FC III and 71 in FC IV. Thirty cases were submitted to BHC due to congestive heart failure. BHC was successful in 288 patients (96%) and the wedge pressure (WP) could be measured in 236 cases (78.7%). The WP was less than 18 mmHg in 47.2% of the patients in FC II, in 44.9% of the patients in FC III and in 35.3% of those in FC IV. Minor complications occurred in 33 cases (11.0%); balloon rupture in 12 (4.0%), transient arrhythmias in 11 (3.7%) and lumen obstruction in another 10 cases (3.3%). Forty five patients (15.0%) presented major complications related to the procedure: pulmonary infarction (PI) in 18 cases (6%), phlebitis in 15 cases (5%), sustained arrhythmias in 10 cases (3.3%), pulmonary artery rupture and endocarditis each in 1 case. The mean age between the group of patients with and without complications was similar the maintenance time as greater in the group of patients with complications: 3.4 +/- 0.2 vs 2.7 +/- 0.1 days (p less than 0.05). We concluded that many patients with clinical evidence of heart failure had WP smaller than 18 mmHg, emphasizing the value of the procedure in patients with complicated MI. The maintenance time was associated with the occurrence of complications, mainly PI and phlebitis.
