A self-powered intracardiac pacemaker in swine model

open access: yesNature Communications
Harvesting biomechanical energy from cardiac motion is an attractive power source for implantable bioelectronic devices. Here, we report a battery-free, transcatheter, self-powered intracardiac pacemaker based on the coupled effect of ...

The prognostic value of the Dandel's index in patients undergoing tricuspid transcatheter edge‐to‐edge repair

open access: yesEuropean Journal of Heart Failure, EarlyView.
Load adaptation indices and concepts. An adapted RV in response to overload increases wall thickness to normalize wall stress and preserve function and morphology. If hemodynamic overload is sustained, it can progress to a maladaptive state and lead eventually to heart failure. CI, cardiac index; Ees, ventricular elastance; Ea, arterial elastance; MPAP,

A systematic review and meta‐analysis on oncological radiotherapy in patients with a cardiac implantable electronic device: Prevalence and predictors of device malfunction in 3121 patients

open access: yesEuropean Journal of Clinical Investigation, Volume 53, Issue 1, January 2023., 2023
Abstract Background The number of patients with cardiac implantable electronic devices (CIEDs) undergoing radiotherapy (RT) for cancer treatment is growing. At present, prevalence and predictors of RT‐induced CIEDs malfunctions are not defined. Methods Systematic review and meta‐analysis conducted following the PRISMA recommendations.
