AI Article Synopsis

  • Papillary muscle rupture is a serious and uncommon complication usually occurring after a heart attack, but it can also be caused by heart procedures.
  • The case discussed involves a patient in cardiogenic shock due to severe mitral regurgitation caused by an iatrogenic rupture during a cardiac examination.
  • The treatment included using a device called Impella CP to support heart function and an urgent surgery to replace the damaged mitral valve, emphasizing the risks linked to minimally invasive heart procedures.

Article Abstract

Papillary Muscle rupture is a rare and potentially life-threatening complication that is typically observed in the days following acute myocardial infarction. Less commonly, rupture of a papillary muscle may arise as an iatrogenic complication of cardiac procedures. We present a case of cardiogenic shock in the setting of torrential mitral regurgitation secondary to iatrogenic papillary muscle rupture during a left ventricular angiogram. The patient was placed on percutaneous mechanical circulatory support with Impella CP and transferred for emergent mitral valve replacement. This case highlights the potential complications of minimally invasive cardiac procedures and reviews the management of acute severe mitral regurgitation.

Background: Muscle-invasive bladder cancer (MIBC) is a prevalent cancer characterized by molecular and clinical heterogeneity. Assessing the spatial heterogeneity of the MIBC microenvironment is crucial to understand its clinical significance.

Methods: In this study, we used imaging mass cytometry (IMC) to assess the spatial heterogeneity of MIBC microenvironment across 185 regions of interest in 40 tissue samples.

Preclinical Experience Using 4D Intracardiac Echocardiography to Guide Cardiac Electrophysiology Procedures.

J Cardiovasc Electrophysiol

December 2024

Division of Cardiovascular Medicine, Cardiac Electrophysiology Section, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Introduction: Intracardiac echocardiography (ICE) is an essential imaging modality for electrophysiology procedures, allowing intraprocedural monitoring, real-time catheter manipulation guidance, and visualization of complex anatomic structures. Four-dimentional (4D) ICE is the next stage in the evolution of the technology, permitting 360° rotation of the imaging plane, simultaneous multiplanar imaging, and volumetric acquisition, similar to transesophageal echocardiography (TEE). In this study, we report our experience with a novel 4D ICE catheter (NuVision, Biosense Webster) in structural electrophysiology procedures and difficult ventricular ablations in a swine preclinical model.

Article Synopsis
  • Cardiac resynchronization therapy (CRT) improves functional mitral regurgitation (FMR) by coordinating heart muscle segments, especially between papillary muscles, beyond just boosting left ventricular (LV) performance.
  • Eighteen patients with dilated cardiomyopathy underwent tests to measure heart function, and biventricular pacing showed a significant reduction in mitral regurgitation despite some patients showing no change in LV pressure.
  • The study concludes that CRT effectively lowers FMR independently of LV systolic function improvements, highlighting the importance of understanding its mechanisms for better treatment outcomes.

The effect of a citrus-derived flavonoid, hesperetin, on the automaticity and contraction of isolated guinea pig myocardium was examined. Hesperetin inhibited the rate of ectopic action potential firing of the pulmonary vein myocardium; the slope of the diastolic depolarization was decreased with minimum change in the action potential waveform. The effect was dependent on the concentration; the EC value for firing rate was 56.

Background: Arrhythmias originating from papillary muscles (PAPs) can be challenging when targeted with catheter ablation. The prevalence and impact of structural abnormalities on PAPs in patients with focal PAP arrhythmias is unknown.

Objectives: The purpose of this study was to analyze, in a consecutive patient series with focal PAP arrhythmias, the impact of structural abnormalities detected by multimodality imaging.
