We present three cases of short-coupled variant of torsade de pointes with review of the literature. These women presented with syncope or presyncope due to torsade de pointes initiated by a short-coupled premature ventricular beat and without evidence of prolonged QT. There were no electrolyte disturbances in all cases, no apparent structural heart disease in two cases and a mild interventricular septum hypertrophy in the other case. One patient took spiramycin and metronidazole and another was taking pheniramin and lincomycin without any evidence of cause to effect relationship. One patient responded to verapamil but died suddendly after 44 months of follow-up. The two others recieved implantable cardioverter-defibrillators and verapamil per os. They still alive 46 and 54 months later. Short-coupled variant of torsade de pointes have a high incidence of sudden death, so it is very important for physicians to identify and treat it promptly. Long-term verapamil treatement is effective but still insufficient and patients should be considered for implantable cardioverter-defibrillator therapy.

Introduction: Medical simulation education has expanded in the remote learning sphere, providing educational opportunities to under-resourced areas and the ability to engage learners limited by time or geographic location. Pediatric resuscitation training has historically been in-person relying on Pediatric Advanced Life Support (PALS) algorithms, yet many pediatric providers are often faced with treating adult or adult-sized patients. Our goal was to develop a tele-simulation remote learning module highlighting possible diagnoses and scenarios that require adult treatment-minded approaches for the pediatric clinician, including the use of Advanced Cardiac Life Support (ACLS) algorithms.

Extended Rhythm Monitoring to Assess for Ventricular Arrhythmias After Transcatheter Pulmonary Valve Replacement With the Harmony Valve.

Circ Cardiovasc Interv

December 2024

Department of Pediatrics, Pediatric Cardiology, Stanford University, Palo Alto, CA. (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.).

Background: Varying rates of nonsustained ventricular tachycardia (NSVT) have been reported early after transcatheter pulmonary valve replacement (TPVR) with the Harmony valve, but data regarding rhythm outcomes beyond hospital discharge are limited. This study aims to characterize ventricular arrhythmias after Harmony TPVR from implant through mid-term follow-up.

Methods: Ventricular arrhythmia data from postimplant telemetry and follow-up extended rhythm monitoring (ERM) were analyzed after Harmony TPVR.

Background: This case highlights the management of concomitant acute myocarditis and congenital long QT syndrome with electrical storm and incessant Torsade de Pointes.

Case Presentation: An 18 years-old Southeast Asian para 1 abortus 0 (P1A0) postpartum patient with cesarean section owing to severe preeclampsia, acute lymphocytic myocarditis, and prolonged QT interval owing to long QT syndrome. She has incessant Torsade de Pointes treated with beta-blocker, lidocaine, overdrive pacing with a temporary transvenous pacemaker, left cardiac sympathetic denervation per video-assisted thoracoscopic surgery, and implantable cardioverter-defibrillator implantation.

Nitazene opioids and the heart: Identification of a cardiac ion channel target for illicit nitazene opioids.

J Mol Cell Cardiol Plus

December 2024

School of Physiology, Pharmacology and Neuroscience, Biomedical Sciences Building, University Walk, Bristol BS8 1TD, UK.

The growing use of nitazene synthetic opioids heralds a new phase of the opioid crisis. However, limited information exists on the toxic effects of these drugs, aside from a propensity for respiratory depression. With restricted research availability of nitazenes, we used machine-learning-based tools to evaluate five nitazene compounds' interaction potential with the hERG potassium channel, a key drug antitarget in the heart.

Introduction: A healthy young woman, age 26 without prior cardiac complications, experienced an out-of-hospital cardiac arrest caused by ventricular fibrillation (VF), which coincided with a fever. Comprehensive diagnostics including echo, CMR, exercise testing, and genetic sequencing, did not identify any potential cause. This led to the diagnosis of idiopathic VF and installment of an implantable cardioverter defibrillator, which six months later appropriately intervened another VF episode under conditions comparable to the first event.
