Repair of total anomalous pulmonary venous connection in adults.

Three cases are presented of adults who underwent successful surgical correction of total anomalous pulmonary venous connection of the supracardiac type. Adults rarely present with this unusual condition but our experience suggests that correction can be performed, using the same techniques that are used in children, with a low operative risk and achieving similar long-term results.

Higher values of hepatic lipase activity in postmenopause: relationship with atherogenic intermediate density and low density lipoproteins.

OBJECTIVE: To investigate the enzymatic activity of hepatic lipase (HL) in postmenopausal women (PMW) and reproductive age women (RAW); and to evaluate the relationship between this enzyme and the atherogenic intermediate density lipoproteins (IDL) and low density lipoproteins (LDL), and antiatherogenic high density lipoproteins (HDL) and its subfractions (HDL2 and HDL3). DESIGN: We studied 55 PMW receiving no hormonal treatment in a cross-sectional study in comparison with a control group of 55 RAW, matched by body mass index. Follicle-stimulating hormone was > 40 mUI/ml in PMW and 3-12 mUI/ml in RAW. PMW presented at least 1 year of natural menopause and no more than 10 years of amenorrhea with E2 serum concentration < 15 pg/ml. RESULTS: HL activity was significantly higher in PMW versus RAW (14.0 +/- 1.4 vs. 10.9 +/- 0.4 micromol of fatty acids/ml of postheparin plasma, respectively, mean +/- SEM, p < 0.001). In PMW, IDL cholesterol showed a positive correlation with LDL cholesterol (r = 0.28, p < 0.05), and HDL2 cholesterol was inversely correlated with HL activity (r = 0.31, p < 0.05). HL was positively correlated with plasma concentration of LDL cholesterol in both groups (r = 0.27, p < 0.05). The higher values of HL activity and IDL cholesterol were independent of age. CONCLUSIONS: Higher HL activity is associated with a more atherogenic profile in PMW.

Recent clinical experience with percutaneous intra-aortic balloon pumping.

From January 1984 to August 1985, 51 out of 2138 patients undergoing cardiac surgery (2.38 per cent) had an intra-aortic balloon pump (IABP) inserted or an attempted insertion. The patients ranged in age from 24 to 68 years (mean 54.2 years). An IABP was inserted preoperatively in four patients, all of whom were in cardiogenic shock; peroperatively in 27 patients who could not be weaned from cardiopulmonary bypass; and postoperatively in 16 patients who had haemodynamic deterioration. Failed insertion occurred in a further four patients. Twenty-eight patients (59.6 per cent) had percutaneous insertion of the balloon, in 17 (36.2 per cent) the common femoral artery was exposed prior to insertion and in two (4.2 per cent) the balloon was inserted into the thoracic aorta. The overall survival rate was 38.3 per cent for patients with successful insertion. Major complications that threatened life or limb occurred in 10.25 per cent of patients. These complications were confined to females and in these patients the percutaneous technique for inserting intra-aortic balloons should be used with caution.
