Blood perfusion status is important in the prognosis of ventricular aneurysm complicated by ventricular septal rupture

Aims Due to its low incidence, poor prognosis, and high mortality in the acute phase, the long‐term prognosis of the left ventricular aneurysm (LVA) complicated by ventricular septal rupture (VSR) has received little attention. This study focus on the long‐term prognosis of patients with LVA complicated by relatively stable VSR. Methods and results Over a decade of retrospection, 68 patients with both LVA and VSR were compared with 136 patients with LVA alone after propensity score matching. Patients with both LVA and VSR were further divided into two groups depending on whether pre‐operative intra‐aortic balloon pump (IABP) was used (23 pre‐operative IABP vs. 45 non‐pre‐operative IABP). The primary endpoint was defined as major adverse cardiovascular and cerebrovascular events, a composite endpoint including mortality, myocardial infarction, revascularization, stroke, and heart failure. Patients with both LVA and VSR were generally in a worse condition upon admission compared with those with LVA alone [percentage of patients in New York Heart Association IV: 42.6% (29/68) vs. 11.0% (15/136), P
