Background: Severe aortic regurgitation (AR) and mitral regurgitation (MR) can lead to left ventricular (LV) systolic dysfunction; however, there are limited data about recovery of LV after surgery for AR or MR. Little is known to guide the management of combined AR and MR (mixed valvular heart disease [VHD]). This study is sought to investigate the predictors of postoperative LV function recovery in left-sided regurgitant VHD with reduced left ventricular ejection fraction (LVEF), especially for mixed VHD.

Article Synopsis
  • - Subclinical thrombus formation at the aortic valve complex (including valvular and perivalvular) occurs frequently after transcatheter aortic valve replacement (TAVR), affecting about 43% of patients in the study.
  • - The study identified small stent diameter and low body surface area as independent predictors of thrombus formation, with decreased renal function linked to leaflet thrombus specifically.
  • - Despite the high incidence of thrombus after TAVR, there were no significant changes in neurological outcomes or new cerebral lesions among patients, indicating that the presence of thrombus may not impact clinical outcomes significantly.

Article Synopsis
  • The study investigated the effects of subclinical leaflet thrombosis (HALT) on bioprosthetic valve function and durability after transcatheter aortic valve replacement (TAVR).
  • In a multicenter trial, HALT was assessed using CT scans and echocardiography, and the study found that HALT was present in 14.2% of patients but did not significantly impact valve mean gradients at six months.
  • Key predictors for structural valve deterioration (SVD) included older age, smaller valve size, and higher post-TAVR pressure gradient, while HALT was not a predictor of SVD.

Health behaviors related to COVID-19 prevention measures, especially vaccination, are used to exemplify mechanisms whereby misinformation and disinformation can spark an "infodemic": a situation in which false information can spread more rapidly and widely than its truthful, science-based counterpart. We define key terminologies and identify potential sources that led to the pandemic infodemic, and highlight the harmful implications of such events. Issues related to scientific communication, how the public perceives information, and factors influencing individuals' decision-making are also discussed.
