Presentation of preload and afterload to isolated heart preparations

The Journal of Physiology, EarlyView.
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, Volume 309, Issue 8, Page 2199-2220, August 2026.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 287-300, August 1, 2026.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Cuspal dissection of aorta during percutaneous coronary intervention to left anterior descending artery managed successfully

IHJ Cardiovascular Case Reports, 2018
Cuspal dissection of aorta during cardiac interventions is rare. It can be asymptomatic or can cause life threatening complications. It can be managed by stenting the ostia of the involved coronary artery or may require surgical intervention when it is ...

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 331-342, August 1, 2026.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Microaxial Flow Pump Support as a Bridge to Transaxillary TAVI‐In‐TAVI in Cardiogenic Shock

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT A 79‐year‐old man presented with cardiogenic shock due to severe degeneration of a prior transcatheter aortic valve. Temporary mechanical circulatory support with a transvalvular microaxial flow pump was initiated, resulting in rapid stabilization.

Coronary Ostia Stenosis After Transcatheter Aortic Valve Implantation

JACC: Cardiovascular Interventions, 2010
A frail 85-year-old woman with symptomatic severe aortic stenosis was evaluated for transcatheter aortic valve implantation (TAVI). The Society of Thoracic Surgeons (STS) risk score and the logistic EuroSCORE were 7.2% and 13.3%, respectively.

Postoperative Nausea and Vomiting After Deep Sedation for Radiofrequency Catheter Ablation in Pediatric Patients

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
This retrospective study investigated the incidence of postoperative nausea and vomiting (PONV) in 70 pediatric radiofrequency catheter ablation procedures under deep sedation. PONV occurred in 17% of procedures, with a significantly higher incidence following left‐sided ablation. Importantly, the majority of PONV symptoms resolved spontaneously within
