Excited to share our new multicenter study published in @JACCJournals highlighting the need for deep phenotyping (#WhyCMR) in dilated and arrhythmogenic cardiomyopathies. @MayoCVFellows @MayoClinicCV @MJAckermanMDPhD @JohnGiudicessi @nl_pereira authors.elsevier.com/a/1j2Rl2d9GH%7…

Cardiology Fellowship applicants- I am looking for a new clinical research fellow for sports cardio to start July 2026! 2 yrs research, then gen cards! Apply to @EmoryMedicine Cardiology if interested! @austinjrim @JasonTsoMD #sportscards

Big thanks to @JohnGiudicessi for the outstanding mentorship! LMNA IgD variants (p.Arg471, p.Arg541) = distinct apical variant w transmural LGE + elevated arrhythmic/stroke risk. Genotype–phenotype drives precision! 🔗 ahajournals.org/doi/epub/10.11… #CardioTwitter #LMNA #ACM

This paper shows what we always suspected: any cut offs values for endocardial voltages for diagnosing scar correlate poorly with histology, at least in non ischemic CMP. The same is likely true for atrium too?

Very important study. This is a paradigm shift. #openaccess MYL4 Identifies Intramural Anatomy of Purkinje Fibers in Human Hearts | JACC: Clinical Electrophysiology jacc.org/doi/abs/10.101…

Cardiac conduction system involvement in STEMI Now we know why AV blocks in inferior STEMI are more common than SA blocks.

Great time at #ACC25 sharing exciting new findings in the fascinating world of genetic cardiomyopathies. Grateful for the chance to connect, learn, and contribute to the future of heart care. @ACCinTouch @MayoClinicCV

Not all apical hypertrophy is the same. We know this from practice. Nice to have data reflecting on this. ahajournals.org/doi/full/10.11… #CardioTwitter
