Rescue procedure for an electrical storm using robotic non-invasive cardiac radio-ablation.

We report here an intensive care patient suffering from an electrical storm due to incessant VT, unresponsive to catheter ablation and anti-arrhythmic drugs, showing an immediate and durable response to electrophysiology-guided cardiac SBRT. PMID: 29753550 [PubMed - as supplied by publisher]

Ventricular tachycardia (VT) circuit is often assumed to be located in the endocardium or epicardium. The plateauing success rate of VT ablation warrants re-evaluation of this mapping paradigm.

Identifying targets for the successful ablation of ventricular tachycardia is a major challenge despite recent advances such as targeting zones of conduction slowing or MRI-identified fibrosis1,2. Once targets are identified, impediments to successful catheter ablation include deep substrates, mid-myocardial locations, and ill-defined anatomic barriers. In an effort to ablate intramural arrhythmia substrates deep to the endocardium, irrigated radiofrequency needle catheters have recently been developed.

ConclusionsAll MVT cases were successfully treated by catheter ablation. We observed high ventricular arrhythmia free rate following catheter ablation during the long-term follow-up period. BrS patients who developed MVT should consider catheter ablation.

AbstractA 34-year-old man, who was previously fit and healthy, died suddenly on exercise. A post-mortem exam performed by forensic pathologists and a toxicological screening were normal; therefore, the cause of death was suspected to be sudden arrhythmic death syndrome, prompting the need for a molecular autopsy. Screening for genetic variations underlying arrhythmogenic genes by next-generation sequencing highlighted a heterozygoussingle-nucleotide variant in the exon n. 94 of theryanodine receptor type 2 gene. This gene, encoding the cardiac ryanodine receptor, is one of the main genetic variants of catecholaminergic pol...

On Saturday morning at the breakfast table surrounded by my husband and kids, I suddenly felt chest pain, palpitations, and was about to collapse. Being an internist, I knew it: arrhythmia. Paramedics at arrival confirmed it. I was running ventricular tachycardia. Out of the chaos surrounding me at that moment, my physician’s brain assessed the […]Find jobs at  Careers by KevinMD.com.  Search thousands of physician, PA, NP, and CRNA jobs now.  Learn more.

Conclusion: Video-assisted CSD should be considered as a treatment option for patients with potentially dangerous arrhythmias that do not respond to conventional treatment, especially in recurrent ventricular tachycardia. PMID: 31588139 [PubMed - in process]

ConclusionsThe multipolar Advisor ™ HD Grid Mapping Catheter in conWAVE provides more efficient point acquisition and greater VT substrate definition of the borderzone particularly at the low-voltage range compared to conSTANDARD. This greater resolution within the low-voltage range facilitated CC definition and quantification wit hin the scar, which is essential in guiding the ablation strategy.
