Note: AMI: acute myocardial infarction; VSR: ventricular septal rupture; PCI: percutaneous coronary intervention; PTCA: percutaneous transluminal coronary angioplasty; ECD: diameter of rupture measured by echocardiography; CTLD: long diameter of rupture measured by CTA; CTSD: short diameter of rupture measured by CTA; CTMD: mean diameter of rupture measured by CTA. 36 patients underwent PCI while the remaining 8 patients received conservative treatments.
