Abstract
AbstractObjectiveTo investigate the efficacy and safety of percutaneous closure of ventricular septal rupture (VSR) after acute myocardial infarction (AMI).MethodsThis retrospective study included 81 patients who underwent transcatheter closure for postinfarction VSR. We analyzed clinical data from hospitalization and the 30‐day follow‐up, compared clinical data from the survival and death groups, and explored the best closure time and the safety and efficacy of occlusion. The risk factors for death at 30 days were analyzed by logistic regression.ResultsC‐reactive protein (CRP), white blood cell counts, N‐terminal pro brain natriuretic peptide (NT‐ProBNP), and aspartate aminotransferase were higher in the death group than in the survival group (p < .01), with a higher rate of application of vasoactive drugs, and a shorter time from AMI to operation (p < .05). At 30 days postocclusion, 19 patients (23.5%) had died. The mortality rate was significantly lower for operation performed 3 weeks after AMI than for operation performed within 3 weeks of AMI (12.5% vs. 48%, p < .001). Devices were successfully implanted in 76 patients, with 16 (21.1%) operation‐related complications and 12 (15.8%) valve injuries. Cardiac function improved significantly (p < .001) at discharge (N = 66) and 30 days after procedure (N = 62). Qp/Qs and pulmonary artery systolic pressure decreased significantly, while aortic systolic pressure increased significantly (p < .001). Additionally, EF and LVDd improved (p < .05) after occlusion. Increases in CRP and NT‐ProBNP were risk factors for death at 30 days after closure (p < .05).ConclusionPercutaneous VSR closure can be a valuable treatment option for suitable patients with VSR.
