Feasibility study shows concordance between image‐based virtual‐heart ablation targets and predicted ECG‐based arrhythmia exit‐sites

Shijie Zhou, Eric Sung, Adityo Prakosa, Konstantinos N. Aronis, more

Pacing and Clinical Electrophysiology > 44 > 3 > 432 - 441

Introduction We recently developed two noninvasive methodologies to help guide VT ablation: population‐derived automated VT exit localization (PAVEL) and virtual‐heart arrhythmia ablation targeting (VAAT). We hypothesized that while very different in their nature, limitations, and type of ablation targets (substrate‐based vs. clinical VT), the image‐based VAAT and the ECG‐based PAVEL technologies...

Esophageal injury associated with catheter ablation for atrial fibrillation: Determinants of risk and protective strategies

Fabrizio R. Assis, Rushil Shah, Bharat Narasimhan, Sravya Ambadipudi, more

Journal of Cardiovascular Electrophysiology > 31 > 6 > 1364 - 1376

Catheter ablation has become an important element in the management of atrial fibrillation. Several technical advances allowed for better safety profiles and lower recurrence rates, leading to an increasing number of ablations worldwide. Despite that, major complications are still reported, and esophageal thermal injury remains a significant concern as atrioesophageal fistula (AEF) is often fatal...

Misdiagnosis of ARVC leading to inappropriate ICD implant and subsequent ICD removal – lessons learned

Apurva Sharma, Fabrizio Assis, Cynthia A. James, Brittney Murray, more

Journal of Cardiovascular Electrophysiology > 30 > 10 > 2020 - 2026

Introduction Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited progressive cardiomyopathy characterized by frequent life‐threatening arrhythmias. The diagnosis of ARVC is challenging and is on the basis of a set of major and minor criteria as described by the modified Task Force Criteria (TFC). We report our clinical experience in a series of patients who were misdiagnosed with...

Regional abnormalities on cardiac magnetic resonance imaging and arrhythmic events in patients with cardiac sarcoidosis

David R. Okada, Eric Xie, Fabrizio Assis, John Smith, more

Journal of Cardiovascular Electrophysiology > 30 > 10 > 1967 - 1976

Background Patients with cardiac sarcoidosis (CS) may present with arrhythmic events (AE): atrioventricular block (AVB) and/ or ventricular arrhythmias (VA). We sought to: (a) use regional analysis of cardiac magnetic resonance imaging (CMR) to describe anatomic and functional phenotypes of patients with CS and AE; (b) Assess the association of regional CMR abnormalities with the combined endpoint...

Feasibility and Safety of Transnasal High Flow Air to Reduce Core Body Temperature in Febrile Neurocritical Care Patients: A Pilot Study

Wendy C. Ziai, Dhaval Shah, Fabrizio R. Assis, Harikrishna Tandri, more

Neurocritical Care > 2019 > 31 > 2 > 280-287

Background Fever is an important determinant of prognosis following acute brain injury. Current non-pharmacologic techniques to reduce fever are limited and induce a shivering response. We investigated the safety and efficacy of a novel transnasal unidirectional high flow air device in reducing core body temperature in the neurocritical care unit (NCCU) setting. Methods This pilot study included...

Arrhythmic outcome of arrhythmogenic right ventricular cardiomyopathy patients without implantable defibrillators

Weijia Wang, Julia Cadrin‐Tourigny, Aditya Bhonsale, Crystal Tichnell, more

Journal of Cardiovascular Electrophysiology > 29 > 10 > 1396 - 1402

Background Implantable defibrillators (ICD) are an important therapy for arrhythmogenic right ventricular cardiomyopathy (ARVC) patients at high risk of sudden death. Given the high appropriate ICD therapy rate, some have argued that the mere act of implanting an ICD inflates the malignant arrhythmia rate in ARVC. Objective To report the arrhythmic course of ARVC patients without ICDs at the fulfillment...

Identification of sarcomeric variants in probands with a clinical diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC)

Brittney Murray, Edgar T. Hoorntje, Anneline S. J. M. te Riele, Crystal Tichnell, more

Journal of Cardiovascular Electrophysiology > 29 > 7 > 1004 - 1009

Aims Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy characterized by ventricular arrhythmias and sudden death. Currently 60% of patients meeting Task Force Criteria (TFC) have an identifiable mutation in one of the desmosomal genes. As much overlap is described between other cardiomyopathies and ARVC, we examined the prevalence of rare, possibly pathogenic sarcomere...

Correlation of right ventricular multielectrode endocardial unipolar mapping and epicardial scar

Jonathan Chrispin, Ali R. Keramati, Fabrizio R. Assis, Satish Misra, more

Pacing and Clinical Electrophysiology > 41 > 4 > 345 - 352

Aims Prior studies identified a relationship between epicardial bipolar and endocardial unipolar voltage. Whether the relationship is valid with smaller multielectrode mapping catheters has not been reported. We explored the association of right ventricular (RV) endocardial unipolar voltage mapping with epicardial bipolar voltage mapping using a multielectrode mapping catheter. Methods Electrograms...

Aravind Krishnan, Alejandro Suarez-Pierre, Todd C. Crawford, Xun Zhou, more

The Annals of Thoracic Surgery > 2018 > 105 > 2 > e51-e53

We describe the novel use of bilateral cardiac sympathectomy in a woman with end-stage heart failure caused by ventricular tachycardia refractory to standard medical therapy who was under consideration for heart transplantation. Postoperatively, our patient has not experienced any symptoms of ventricular tachycardia, has returned to normal physical activity, and is no longer under consideration for...

The Extent of Left Atrial Low-Voltage Areas Included in Pulmonary Vein Isolation Is Associated With Freedom from Recurrent Atrial Arrhythmia

Dong Huang, Jing-bo Li, Tarek Zghaib, Esra Gucuk Ipek, more

Canadian Journal of Cardiology > 2018 > 34 > 1 > 73-79

The extent of left atrial (LA) baseline low-voltage areas (LVA-B), which may be a surrogate for fibrosis, is associated with recurrent atrial fibrillation (AF) after ablation. This study aimed to assess the relationship between the extent of LVA-B isolated by ablation (LVA-I) and AF recurrence.The study cohort included 159 consecutive patients with drug-refractory AF who underwent an initial AF ablation...

Anterior pericardial access to facilitate electrophysiology study and catheter ablation of ventricular arrhythmias: A single tertiary center experience

Ali R. Keramati, Deeptankar DeMazumder, Satish Misra, Jonathan Chrispin, more

Journal of Cardiovascular Electrophysiology > 28 > 10 > 1189 - 1195

Introduction Epicardial ablation is becoming an important part of management in patients with ventricular tachycardia (VT). Posterior epicardial access via the Sosa or needle‐in‐needle (NIN) approach for epicardial VT ablation is considered to be the method of choice for most electrophysiologists. Anterior epicardial access as an alternative technique has recently been proposed, but there are limited...

Feature tracking CMR reveals abnormal strain in preclinical arrhythmogenic right ventricular dysplasia/ cardiomyopathy: a multisoftware feasibility and clinical implementation study

Mimount Bourfiss, Davis M. Vigneault, Mounes Aliyari Ghasebeh, Brittney Murray, more

Journal of Cardiovascular Magnetic Resonance > 2017 > 19 > 1 > 1-13

Background Regional right ventricular (RV) dysfunction is the hallmark of Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C), but is currently only qualitatively evaluated in the clinical setting. Feature Tracking Cardiovascular Magnetic Resonance (FT-CMR) is a novel quantitative method that uses cine CMR to calculate strain values. However, most prior FT-CMR studies in ARVD/C have...
