Background
To date, moderate concomitant valvular heart diseases have been scarcely studied. This study aimed to further define predictors of long-term outcomes in patients diagnosed with concomitant moderate aortic and mitral valve disease at a tertiary center.
Methods
In this cohort we included 3257 patients (aged 71.7 ± 12.9 years; 55.2% male; 83.1% white) diagnosed with concomitant moderate aortic and mitral valves diseases who presented to the Cleveland Clinic between 2010 and 2018. The patients’ demographic, clinical and echocardiographic variables were collected. The primary endpoint of the study was the long-term composite outcome defined as heart failure hospitalization or all-cause mortality. We then conducted a univariate and multivariate cox proportional hazard survival analysis for the primary endpoint.
Results
The patients were followed up for 21.8 months. Baseline demographic characteristics are presented in table 1. Multiple demographic, clinical, and echo variables were evaluated. Using a univariate Cox proportional hazard survival analysis, older Age, history of smoking, Diabetes, Hypertension, Chronic Kidney Disease (CKD), Coronary Artery Disease (CAD), Atrial Fibrillation (Afib), Dyslipidemia, higher Right Ventricular Systolic Pressure (RVSP), higher New York Heart Association (NYHA) class, and lower Left Ventricular Ejection Fraction (LVEF) were associated with worse long-term outcomes. Additionally, patients who underwent an aortic (39.1%) or a mitral valve intervention (29.4%) were associated with better long-term outcomes (HR, 0.710, 0.708; respectively). In comparison, on Multivariable Cox analysis, female sex was significantly associated with worse survival (HR of 1.151, p-value=0.019). However, older Age, history of smoking, Diabetes, CKD, higher RVSP, NYHA class 2, 3, and 4, and lower LVEF remained significantly associated with worse long-term (table 2). Aortic valve intervention remained significantly associated with better survival (HR, 0.861, P-value=0.021). Compared to the Aortic Stenosis/ Mitral Stenosis (AS/MS) group, univariate analysis showed that patients in the Aortic Regurgitation/Mitral Regurgitation (AR/MR), and the AR/MS groups were significantly associated with better long term outcomes (HR, 0.738, HR, 0.575; respectively). Conversely, on Multivariate Cox analysis, AR/MR and AS/MR groups were significantly associated with better survival compared to AS/MS group (HR, 0.580, HR, 0.716; respectively).
