SUMMARYWe report a rescued 37-year-old woman in her 30 th week of gestation with massive pulmonary thromboembolism who was admitted to our cardiac care unit with progressive dyspnea and 2 episodes of syncope. Helical chest CT showed massive pulmonary thromboembolism of both pulmonary arteries. Although 26,000 U/day of heparin was administered following insertion of a temporary filter, hemodynamic evaluation documented no improvement. Since pulmonary artery (PA) pressure increased from 62/22 mmHg to 80/ 24 mmHg just after an emergency cesarean section on day 2, an emergency transcatheter thrombectomy was performed and it showed decreased PA pressure following extensive thrombus aspiration. Mother and baby were discharged with no complications.(Int Heart J 2007; 48: [269][270][271][272][273][274][275][276]

Although slow/no-reflow is a serious problem complicating primary percutaneous coronary interventions (PCI) for acute myocardial infarction (AMI) and is associated with a poor prognosis, its efficacious treatment remains problematic. We compared the acute, in-hospital and long-term (1 year) effects of nitroprusside (NTP) with those of nicorandil (NC) on the slow/no-reflow phenomenon. Forty-nine of 442 consecutive patients with AMI who underwent primary PCI complicated by slow/no-reflow and who received intracoronary NTP (n = 25) or NC (n = 24) administration were studied. Both NTP and NC induced significant improvements in coronary flow, with increases in TIMI flow grade from 1.64 ± 0.62 to 2.74 ± 0.36 (p < 0.001) and 1.60 ± 0.86 to 2.23 ± 0.91 (p < 0.001), and in corrected TIMI frame count from 37.8 ± 15.1 to 13.7 ± 7.1 (p < 0.001) and 30.8 ± 20.7 to 19.3 ± 17.9 (p < 0.001), respectively. The degree of improvement in TIMI flow grade (post-pre/pre) and TIMI frame count (pre-post/pre) showed that NTP was more effective than NC (NTP vs. NC: 0.88 ± 0.79, 0.37 ± 0.37, p = 0.008; 0.59 ± 0.23, 0.36 ± 0.27, p = 0.003, respectively). Congestive heart failure did not tend to last beyond 3 days after onset in the NTP group, which was more than in the NC group, during hospitalization (1/25, 4/24, p = 0.143, respectively). At the 1-year follow-up, the NTP group tended to show more improvement than the NC group in MACE (5/25, 9/24, p = 0.175, respectively). NTP is a more effective treatment for slow/no-reflow associated with PCI in patients with AMI and may improve long-term clinical outcomes compared with NC.
