Dr Aaysha Cader, Social media editor for JACC Interventions discusses the paper, Transcatheter Edge-to-Edge Repair for SAM-Related Mitral Regurgitation in Patients With HCM: The TRANSPARENT Registry, with Professor Luca Testa.
Dr. Francis Marchlinski highlights new research comparing high‑density electroanatomical mapping with cardiac MRI in non‑ischemic cardiomyopathy. He explains how omnipolar mapping more accurately reflects MRI‑defined scar patterns—especially in deeper layers—and why this technology may offer a valuable alternative when MRI is limited or unavailable. A concise look at emerging tools reshaping arrhythmic risk assessment.

JACC: CardioOncology Volume 8 Issue 1 Full Issue Summary with Introduction by Dr. Bonnie Ky, Editor-in-Chief
Polygenic risk scores showed associations with several cardiometabolic outcomes in breast cancer survivors but did not improve prediction beyond traditional clinical factors. Their performance varied across ancestry groups and was weakened in patients exposed to cardiotoxic therapies, highlighting limits of current genetic risk tools.
This study analyzes over 2,600 transthyretin V142I variant carriers in the Million Veteran Program and finds significantly elevated risks of heart failure, cardiomyopathy, arrhythmias, neuropathy, and musculoskeletal complications compared with matched controls. Despite these risks, amyloidosis was rarely diagnosed clinically, underscoring major gaps in recognition and the need for earlier identification and multidisciplinary intervention.
This study of 801 multiple myeloma patients found that atrial fibrillation occurred in 5.5% within 90 days after autologous stem cell transplantation—nearly double previously reported rates—indicating disease‑specific risks. AF strongly predicted mortality from non‑relapse causes and may serve as a marker of physiological vulnerability, emphasizing the value of expanded pre‑transplant cardiac assessment and monitoring.
Researchers used genome‑wide CRISPR/Cas9 loss‑of‑function screens in cardiomyocytes to identify RARA and SPNS1 as key modulators of doxorubicin cardiotoxicity, highlighting pathways that influence both injury susceptibility and intracellular drug handling. Activation of RARA reduced toxicity without impairing anticancer effects, while SPNS1 loss caused harmful drug accumulation, offering new mechanistic insights and potential therapeutic targets.
