Accuracy of Electrocardiographic Criteria for Atrial Enlargement: Validation with Cardiovascular Magnetic Resonance
Tsao, Connie Wei-Lee; Josephson, Mark; Hauser, Thomas Henry; O'Halloran, Thomas D.; Agarwal, Anupam; Manning, Warren J.; Yeon, Susan B. (BioMed Central, 2008)Background: Anatomic atrial enlargement is associated with significant morbidity and mortality. However, atrial enlargement may not correlate with clinical measures such as electrocardiographic (ECG) criteria. Past studies ... -
Beat‐to‐Beat Spatiotemporal Variability in the T Vector Is Associated With Sudden Cardiac Death in Participants Without Left Ventricular Hypertrophy: The Atherosclerosis Risk in Communities (ARIC) Study
Waks, Jonathan W.; Soliman, Elsayed Z.; Henrikson, Charles A.; Sotoodehnia, Nona; Han, Lichy; Agarwal, Sunil K.; Arking, Dan E.; Siscovick, David S.; Solomon, Scott D.; Post, Wendy S.; Josephson, Mark E.; Coresh, Josef; Tereshchenko, Larisa G. (Blackwell Publishing Ltd, 2015)Background: Despite advances in prevention and treatment of cardiovascular disease, sudden cardiac death (SCD) remains a clinical challenge. Risk stratification in the general population is needed. Methods and Results: ... -
Cardiovascular Magnetic Resonance Imaging of Scar Development Following Pulmonary Vein Isolation: A Prospective Study
Hsing, Jeff; Peters, Dana C.; Knowles, Benjamin R.; Manning, Warren J.; Josephson, Mark E. (Public Library of Science, 2014)Aims Cardiovascular magnetic resonance (MR) provides non-invasive assessment of early (24-hour) edema and injury following pulmonary vein isolation (by ablation) and subsequent scar formation. We hypothesize that 24-hours ... -
Characterization of Respiratory and Cardiac Motion from Electro-Anatomical Mapping Data for Improved Fusion of MRI to Left Ventricular Electrograms
Roujol, Sébastien; Anter, Elad; Josephson, Mark E.; Nezafat, Reza (Public Library of Science, 2013)Accurate fusion of late gadolinium enhancement magnetic resonance imaging (MRI) and electro-anatomical voltage mapping (EAM) is required to evaluate the potential of MRI to identify the substrate of ventricular tachycardia. ... -
Coexistent Types of Atrioventricular Nodal Re-Entrant Tachycardia: Implications for the Tachycardia Circuit
Katritsis, Demosthenes G.; Marine, Joseph E.; Latchamsetty, Rakesh; Zografos, Theodoros; Tanawuttiwat, Tanyanan; Sheldon, Seth H.; Buxton, Alfred E.; Calkins, Hugh; Morady, Fred; Josephson, Mark E. (Lippincott Williams & Wilkins, 2015)Background— There is evidence that atypical fast–slow and typical atrioventricular nodal re-entrant tachycardia (AVNRT) do not use the same limb for fast conduction, but no data exist on patients who have presented with ... -
Electrocardiographic Deep Terminal Negativity of the P Wave in V1 and Risk of Sudden Cardiac Death: The Atherosclerosis Risk in Communities (ARIC) Study
Tereshchenko, Larisa G.; Henrikson, Charles A.; Sotoodehnia, Nona; Arking, Dan E.; Agarwal, Sunil K.; Siscovick, David S.; Post, Wendy S.; Solomon, Scott D.; Coresh, Josef; Josephson, Mark E.; Soliman, Elsayed Z. (Blackwell Publishing Ltd, 2014)Background: Identifying individuals at risk for sudden cardiac death (SCD) is of critical importance. Electrocardiographic (ECG) deep terminal negativity of P wave in V1 (DTNPV1), a marker of left atrial abnormality, has ... -
Feasibility of real time integration of high-resolution scar images with invasive electrograms in electro-anatomical mapping system in patients undergoing ventricular tachycardia ablation
Roujol, Sebastien; Basha, Tamer; Tan, Alex Y; Anter, Elad; Buxton, Alfred E; Josephson, Mark; Nezafat, Reza (BioMed Central, 2013) -
Left Atrial Scar Assessment Using Imaging With Isotropic Spatial Resolution and Compressed Sensing
Akcakaya, Mehmet; Hong, Susie; Chan, Raymond Ho Ming; Basha, Tamer; Moghari, Mehdi H.; Kissinger, Kraig V; Goddu, Beth; Josephson, Mark; Manning, Warren J.; Nezafat, Reza (BioMed Central, 2012)Summary. We assess left atrial scar using late gadolinium enhancement (LGE) with isotropic spatial resolution of \(1.4^3 mm^3\) by using highly accelerated LOST [1] reconstruction. Background. Atrial fibrillation (AF) is ... -
Prognostic value of pulmonary vein size in prediction of atrial fibrillation recurrence after pulmonary vein isolation: a cardiovascular magnetic resonance study
Hauser, Thomas H.; Essebag, Vidal; Baldessin, Ferdinando; McClennen, Seth; Yeon, Susan B.; Manning, Warren J.; Josephson, Mark E. (BioMed Central, 2015)Background: The relationship between pulmonary vein (PV) anatomy and successful catheter ablation of atrial fibrillation (AF) is poorly understood Methods: First-pass contrast enhanced PV magnetic resonance angiography was ... -
Towards cardiac and respiratory motion characterization from electrophysiology data for improved real time MR-integration
Roujol, Sebastien; Tan, Alexandre Korarithi; Anter, Elad; Josephson, Mark; Nezafat, Reza (BioMed Central, 2013)Electro-anatomical voltage mapping (EAM) is an invasive technique used for the identification of ventricular tachycardia (VT) substrate and subsequent guidance of VT ablation [1]. The mapping of VT substrate is very time ...
