Efficacy of endocardial ventricular tachycardia (VT) ablation in arrhythmogenic right cardiomyopathy/dysplasia may be limited by epicardial VT, thickening, or both. We sought to characterize the versus substrate, measure free wall thickness, and determine efficacy patients with cardiomyopathy/dysplasia.Thirteen consecutive (3 female; aged 43+/-15 years; range, 17 70 years) undergoing sinus rhythm voltage mapping VT after failed were included. In each patient, low bipolar area (<1.0 mV for...
Inappropriate sinus tachycardia (IST) is a common observation in patients with post-COVID-19 syndrome (PCS) but has not yet been fully described to date. To investigate the prevalence and mechanisms underlying IST prospective population of PCS patients. Consecutive admitted Unit between June December 2020 resting rhythm rate ≥ 100 bpm were prospectively enrolled this study further examined by an orthostatic test, 2D echocardiography, 24-h ECG monitoring (heart variability was surrogate for...
ECG criteria identifying epicardial (EPI) origin for ventricular tachycardia (VT) in nonischemic cardiomyopathy have not been determined. Endocardial (ENDO) and EPI basal left ventricle fibrosis characterizes the VT substrate.We assessed QRS from 102 basal-superior/lateral 67 comparable ENDO pace maps 14 patients with cardiomyopathy. Pace mapping focused on low bipolar voltage areas. Published morphology criteria: q wave lead I (QWLI) no waves inferior leads interval pseudo-delta > or =34...
Background: Myocardial fibrosis is key for atrial fibrillation maintenance. We aimed to test the efficacy of ablating cardiac magnetic resonance (CMR)-detected plus pulmonary vein isolation (PVI). Methods: This was an open-label, parallel-group, randomized, controlled trial. Patients with symptomatic drug-refractory (paroxysmal and persistent) undergoing first or repeat ablation were randomized in a 1:1 basis receive PVI CMR-guided (CMR group) alone (PVI-alone group). The primary end point...
BACKGROUND: Sacubitril/valsartan (Sac/Val) is superior to angiotensin-converting enzyme inhibitors in reducing the risk of heart failure hospitalization and cardiovascular death, but its mechanistic data on myocardial scar after infarction (MI) are lacking. The objective this work was assess effects Sac/Val inflammation, fibrosis, electrophysiological properties, ventricular tachycardia inducibility post-MI remodeling swine. METHODS: After MI, 22 pigs were randomized receive β-blocker (BB;...
Chagasic cardiomyopathy (CC) is the most frequent nonischemic substrate causing left ventricular (LV) tachycardia in Latin America. Systematic characterization of LV epicardial/endocardial scar distribution and density CC has not been performed. Additionally, usefulness unipolar endocardial electroanatomic mapping to identify epicardial assessed this setting.Nineteen patients with undergoing detailed ablation were included. A total 8494 6331 voltage signals 314 matched pairs points analyzed....
Background: Complex fractionated atrial electrograms (CFEs) have been described as a target during fibrillation (AF) ablation; however, the mechanism leading to CFEs is poorly understood. We used noncontact mapping in canine model of AF determine activation patterns areas CFEs. Methods: Sustained was induced 10 canines with 10–12 weeks tachy‐pacing at 440 ppm. A roving catheter and multielectrode array (MEA) were deployed left atrium (LA). NavX software construct contact bipolar CFE LA map....
ABSTRACT Background Ethanol infusion into the vein of Marshall (EI‐VOM) is an adjunctive therapy to pulmonary isolation (PVI), which improves efficacy persistent atrial fibrillation (AF) ablation procedures. It unknown how EI‐VOM scar formation impacts left atrium (LA) structure and function. Objective To characterize after EI‐VOM, its impact on LA function, by cardiac magnetic resonance (CMR). Methods Consecutive patients referred for AF ablation, or any repeat procedure, were included....
Incremental Pacing for the Diagnosis of Cavotricuspid Isthmus Block. Background: Complete conduction block cavotricuspid isthmus (CTI) reduces atrial flutter recurrences after ablation. rapid pacing may distinguish slow from complete CTI block. Methods and Results: Fifty‐two patients (67 ± 9 years) undergoing 55 ablation procedures were included. With ablation, double potentials (DPs) separated by an isoelectric line ≥30 ms obtained. (600–250 ms) was performed coronary sinus (CS) low lateral...
The AMI code is a regional network enhancing rapid and widespread access to reperfusion therapy (giving priority primary angioplasty) in patients with acute ST-segment elevation myocardial infarction (STEMI). We aimed assess the long-term control of conventional cardiovascular risk factors after STEMI among included registry. Four hundred fifty-four were prospectively between June-2009 April-2013. Clinical characteristics collected at baseline. morbidity/mortality was assessed 6-months...
The difference between the stimulus-atrial and ventriculo-atrial intervals (SA-VA) post-pacing interval tachycardia cycle length (PPI-TCL) during entrainment from right ventricular apex distinguishes atrioventricular node reentrant (AVNRT) orthodromic (AVRT). We hypothesized that these features still apply when is performed para-Hisian region.Forty-seven supraventricular tachycardias (34 AVNRT/13 AVRT) were included. SA-VA PPI-TCL obtained in all patients by using two right-sided diagnostic...
To evaluate the long-term mortality rate and to determine independent risk factors in patients with bifascicular block (BFB). Patients BFB are known have a higher than general population, not only related progression atrio-ventricular but also due presence of malignant ventricular arrhythmias. Previous observational epidemiological studies including high proportion structural heart disease shown an important cardiac may reflect real outcome BFB.From March 1998 until December 2006, we...
