Percutaneous Endocardial Occlusion of Incompletely Surgically‐Ligated Left Atrial Appendage
17-05-2013 | ARASH ARYANA, DIOGO CAVACO, ARVIN ARTHUR, PADRAIG GEAROID O'NEILL, PEDRO ADRAGÃO, ANDRÉ D'AVILA, Journal of Cardiovascular Electrophysiology, 2013
Abstract Introduction Surgical ligation of the left atrial appendage is considered standard of care in patients who undergo mitral valve surgery or as an adjunct to a surgical Maze procedure for treatment of atrial fibrillation (AF). However, several studies have demonstrated that this ...
Left Atrial Massive Thrombus Formation on the Transseptal Sheath Despite Adequate Anticoagulation with Warfarin and Heparin During Pulmonary Vein Isolation
17-05-2013 | RADOSLAW MAREK KIEDROWICZ, JAROSLAW KAZMIERCZAK, Journal of Cardiovascular Electrophysiology, 2013
Abstract A 52‐year‐old male with CHA2DS2VASc score 4 was referred for cryoballoon ablation of atrial fibrillation. The patient was on warfarin that was not stopped prior to the ablation with INR of 2.3 on admission. Transesophageal echocardiographic examination revealed no evidence of the ...
Occurrence of Steam Pops during Irrigated RF Ablation: Novel Insights from Microwave Radiometry
14-05-2013 | JACOB S. KORUTH, SRINIVAS DUKKIPATI, SANDEEP GANGIREDDY, JOHN MCCARTHY, DARREN SPENCER, ALAN D. WEINBERG, MARC A. MI ..., Journal of Cardiovascular Electrophysiology, 2013
Abstract Background The disparity between catheter and tissue temperatures during irrigated RF ablation frustrates one's ability to predict steam pops. Microwave radiometry allows for “volumetric” temperature assessment – i.e., within a circumscribed volume around the catheter tip‐ ...
Multi‐Sensor Esophageal Temperature Probe Used During Radiofrequency Ablation for Atrial Fibrillation is Associated With Increased Intraluminal Temperature Detection And Increased Risk of Esophageal Injury Compared to Single‐Sensor Probe
12-05-2013 | BRETT J. CARROLL, FERNANDO M. CONTRERAS‐VALDES, E. KEVIN HEIST, CONOR D. BARRETT, STEPHAN B. DANIK, JEREMY N. RUSKIN ..., Journal of Cardiovascular Electrophysiology, 2013
Abstract Background Radiofrequency (RF) ablation in the posterior left atrium has risk of thermal injury to the adjacent esophagus. Increased intraluminal esophageal temperature has been correlated with risk of esophageal injury. The objective of this study was to compare esophageal ...
Pro‐arrhythmic Effect of Pacing Mode Reprogramation in a Patient with a Congenital Long‐QT Syndrome
12-05-2013 | ANDREA DI CORI, GIULIO ZUCCHELLI, SIMONE ROMANO, MARIA GRAZIA BONGIORNI, Journal of Cardiovascular Electrophysiology, 2013
Abstract A 34‐year‐old woman with a congenital long‐QT syndrome LQTS type 2, implanted 10 years before with a single chamber implantable defibrillator (ICD) for secondary prevention, was admitted to our hospital to remove the malfunctioning ventricular ICD lead (Endotak Reliance S 0128, ...
Differential Effects of the β‐Adrenoceptor Blockers Carvedilol and Metoprolol on SQT1‐ and SQT2‐Mutant Channels
07-05-2013 | ILONA BODI, GERLIND FRANKE, NAGA DEEPA PANTULU, KEZHONG WU, STEFANIE PEREZ‐FELIZ, CHRISTOPH BODE, MANFRED ZEHENDER, ..., Journal of Cardiovascular Electrophysiology, 2013
Abstract Background N588K‐KCNH2 and V307L‐KCNQ1 mutations lead to a gain‐of‐function of IKr and IKs thus causing short‐QT syndromes (SQT1, SQT2). Combined pharmacotherapies using K+‐channel‐blockers and β‐blockers are effective in SQTS. Since β‐blockers can block IKr and IKs, we aimed ...
Incessant Tachycardia after Radiofrequency Ablation of Accessory Pathway
07-05-2013 | YEN‐CHANG HUANG, LI‐WEI LO, YENN‐JIANG LIN, SHIH‐ANN CHEN, Journal of Cardiovascular Electrophysiology, 2013
Abstract A 43‐year‐old male without structural heart disease underwent electrophysicology study for recurrent palpitation. Electrocardiogram recordings showed sinus rhythm without preexcitation. Baseline sinus cycle length was 656 msec, atrial‐His (AH) and His‐ventricular (HV) intervals ...
Apamin‐Sensitive Calcium‐Activated Potassium Currents in Rabbit Ventricles with Chronic Myocardial Infarction
07-05-2013 | YOUNG SOO LEE, PO‐CHENG CHANG, CHIA‐HSIANG HSUEH, MITSUNORI MARUYAMA, HYUNG WOOK PARK, KYOUNG‐SUK RHEE, YU‐CHENG HSI ..., Journal of Cardiovascular Electrophysiology, 2013
Abstract Introduction Apamin‐sensitive small‐conductance calcium‐activated potassium current (IKAS) is increased in heart failure. It is unknown if myocardial infarction (MI) is also associated with an increase of IKAS. Methods and Results We performed Langendorff perfusion and ...
Effects of Open‐Irrigated Radiofrequency Ablation Catheter Design on Lesion Formation and Complications: In Vitro Comparison of Six Different Devices
07-05-2013 | JOSE M GUERRA, ESTHER JORGE, SILVIA RAGA, CAROLINA GÁLVEZ‐MONTÓN, CONCEPCIÓN ALONSO‐MARTÍN, ENRIQUE RODRÍGUEZ‐FONT, ..., Journal of Cardiovascular Electrophysiology, 2013
Abstract Introduction Open‐irrigated radiofrequency ablation catheters with slight differences in tip architecture are widely used, although limited comparative data are available. The purpose of this study was to compare the lesion size and potential complications produced by ...
Adenosine Testing in atrial Flutter Ablation: Unmasking of Dormant Conduction across the Cavotricuspid Isthmus and risk of Recurrence
03-05-2013 | GUSTAVO X. MORALES, LAURENT MACLE, PAUL KHAIRY, RICHARD CHARNIGO, EVAN DAVIDSON, SERGIO THAL, CK CHING, NICOLAS LELL ..., Journal of Cardiovascular Electrophysiology, 2013
Abstract Background Adenosine‐induced hyperpolarization may identify pulmonary veins at risk of reconnection following electrical isolation for atrial fibrillation. The potential role of adenosine testing in other arrhythmic substrates, such as cavotricuspid isthmus (CTI)‐dependent ...
