Background: Acute severe aortic regurgitation (AAR) is an uncommon etiology of hemodynamic instability requiring urgent surgical intervention. We sought to describe its etiology, patient characteristics and surgical outcomes in a large tertiary referral center.
Methods: All patients (pts) admitted to the Cardiac ICU, between Jan-10 and Dec-15, with AAR requiring surgical intervention were identified. The etiology was determined by chart review and classified as native valve endocarditis (NVE), prosthetic valve endocarditis (PVE), aortic dissection (AoD) and others (including prosthetic valve failure). Baseline variables were collected. Outcomes included mortality at 30 days and 1-year, post-op stroke and dialysis.
Results: We identified 407 patients with a mean age of 57(+/- 16) years and 76% were male. NVE was the most common cause (N=170, 42%) with the lowest mean age (52+/-16) at presentation. Surgery length and perfusion times were highest in PVE (median of 455 min and 190 min, respectively). Table 1 presents baseline variables along with the outcomes by etiology. The overall 30-day and 1-year mortality rates were 2.5% and 5.2%, respectively with no significant differences by etiology. Although not statistically significant, the rate of stroke was numerically higher in PVE and AoD, Post-op dialysis occurred more in AoD and PVE.
Conclusions: NVE is the commonest etiology of AAR. Surgical outcomes are excellent with no differences in overall 30-day and 1-year mortality regardless of etiology.
