Comparative StudySurgical valvotomy and repair for neonatal and infant congenital aortic stenosis achieves better results than interventional catheterization.
This study sought to compare outcomes after surgical valvuloplasty and balloon dilation of the aortic valve in neonates and infants. ⋯ Surgical valvuloplasty remains the best approach to treat neonates and infants with congenital aortic stenosis. After surgery, a higher proportion of patients remain free of re-intervention than after interventional catheterization and the relief of their stenosis lasts longer.

Cardiac arrest at exercise facilities: implications for placement of automated external defibrillators.
This study sought to characterize the relative frequency, care, and survival of sudden cardiac arrest in traditional indoor exercise facilities, alternative indoor exercise sites, and other indoor sites. ⋯ We observed a higher rate of cardiac arrests at some alternative exercise facilities than at traditional exercise sites. Survival was higher at exercise sites than at nonexercise indoor sites. These data have important implications for automated external defibrillator placement.

Impaired cardiac baroreflex sensitivity predicts response to renal sympathetic denervation in patients with resistant hypertension.
This study sought to evaluate cardiac baroreflex sensitivity (BRS) as a predictor of response to renal sympathetic denervation (RDN). ⋯ Impaired cardiac BRS identifies patients with resistant hypertension who respond to RDN.

Comparative StudyWearable cardioverter-defibrillator use in patients perceived to be at high risk early post-myocardial infarction.
The aim of this study was to describe usage of the wearable cardioverter-defibrillator (WCD) during mandated waiting periods following myocardial infarction (MI) for patients perceived to be at high risk for sudden cardiac arrest (SCA). ⋯ During the 40-day and 3-month waiting periods in patients post-MI, the WCD successfully treated SCA in 1.4%, and the risk was highest in the first month of WCD use. The WCD may benefit individual patients selected for high risk of SCA early post-MI.
