Kim MS, Kim JH, Joo HC, et al. - Researchers assessed the echocardiographic prognostic factors related to improved left ventricular (LV) systolic function following aortic valve replacement, and also they compared the long‐term results post-aortic valve replacement in chronic aortic regurgitation (AR) patients with or without LV dysfunction. Participants were 280 patients who received aortic valve replacement due to chronic aortic regurgitation. A comparison was performed between patients with reduced LV systolic function (LV ejection fraction [LVEF] < 50%; group reduced LVEF [rEF]; N = 80) vs those with preserved LV systolic function (LVEF ≥ 50%; group preserved LVEF; N = 200). At postoperative 10 years, overall and cardiac mortality‐free survival rates were identified to be 80.1% and 92.9% in group rEF and 87.3% and 97.2% in group preserved LVEF, respectively. Overall, in patients with chronic aortic regurgitation, long‐term results and survival following aortic valve replacement were shown to be associated with preoperative LV function. There was a correlation of preoperative early diastolic transmitral flow velocity/mitral annular tissue velocity ratio with the postoperative improvement or normalization of LVEF as well as long‐term survival, specifically in group rEF patients.
