3.3.1. Basic characteristics
Among 462 patients with PIVSD, 47.2% had CS (95%CI: 0.267-0.676)
patients, which results from 18 included articles (155/333). About
35.8% (95%CI: 0.114- 0.602) patients needed IABP and
49.4%(95%CI: 0.217- 0.772) needed inotropes,seventeen (192/325)
and twelve (102/195) included studies were enrolled. Coronary
single-vessel, double-vessel and triple-vessel disease were present in
48.9% (132/270), 34.8% (94/270), and 16.3% (44/270) of patients,
respectively. Revascularization and Prior surgical closure rate was
39.4% (95%CI: 0.221- 0.568) and 80.9% (95%CI:
0.010- 0.355), respectively eighteen (119/331) and
twenty-one(71/333) included articles were assessed for this outcome. The
rate of primary closure at the acute phase reported in twenty-one
studied (155/360) was 29.7% (95%CI: 0.095- 0.499). The weighted
mean results were as follows: time from AMI to VSD and time to VSD
closure was 2.6 days, 17.3 days. The defect size and device size were
13.1 mm and 19.6 mm. The clinical follow-up time was 589.8 days. Table 1
summarizes the initial assessment results of 27 studies.
