Enhancing Evidence Generation by Linking Randomized Clinical Trials to Real‐World Data: The INVESTED‐Medicare Linkage Study

Clinical Pharmacology &Therapeutics, EarlyView.
Real‐world evidence (RWE) derived from real‐world data (RWD) can complement randomized controlled trials (RCTs), yet the validity of RWD relative to RCT data remains insufficiently characterized. We obtained post hoc consent and linked individual participant data from the US‐based INVESTED trial (2016–2019) with Medicare fee‐for‐service claims (2012 ...

Hemodynamic loading regulates formation and patterning of atrial pectinate muscles in the chick embryo

Developmental Dynamics, EarlyView.
Development and differentiation of the atrial myocardium. Hemodynamic loading triggers shear stress response, which is essential for pectinate muscle formation; mechanical stretching is important for the expression of chamber myocardium markers and proper maturation of the atrial contractile and conductive properties.

Implantable cardiac monitor and leadless pacemaker in the management of syncope due to intermittent high-degree atrioventricular block: a case report

Journal of Cardiothoracic Surgery
Background Lead dislodgements, tricuspid valve failure, and wound infections are prominent issues addressed by leadless pacemakers (LPM). These devises have emerged as viable alternatives to conventional transvenous pacemakers.

Magnetic Resonance Imaging Conditional Pacemakers: Rationale, Development and Future Directions

Indian Pacing and Electrophysiology Journal, 2012
Pacemakers and other cardiac implantable electronic devices (CIEDs) have long been considered an absolute contraindication to magnetic resonance imaging (MRI), a crucial and growing imaging modality. In the last 20 years, protocols have been developed to

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

Worsening Heart Failure due to AV Dissociation From Safety Mode in CRT‐P: A Case Requiring Urgent Generator Replacement

Annals of Noninvasive Electrocardiology
Boston Scientific reported that dual chamber INGENIO family pacemakers or cardiac resynchronization therapy pacemakers (CRT‐P) may initiate safety mode. Once Safety Mode is activated, telemetry with the programmer becomes unavailable.
