Fifty open tibial fractures were treated with the Ex-fi-re external fixation system from 1987 to 1994. According to the Gustilo and Anderson classification, there were 12 Grade I, 14 Grade II, 10 Grade IIIA, 13 Grade IIIB, and 1 Grade IIIC injuries. Eight fractures were segmental. The average patient patient age was 39 years (range, 16-85 years). With the(More)
INTRODUCTION Previous studies have validated the use of impedance fall as a measure of the effects of ablation. We investigated whether catheter-to-tissue contact force correlated with impedance fall during atrial fibrillation ablation. METHODS AND RESULTS A total of 394 ablation points from 35 patients who underwent atrial fibrillation ablation were(More)
Substrate-based radiofrequency ablation for treatment of atrial fibrillation (AF) is still under development. The purpose of this study was to investigate the different characteristics and distribution of complex fractionated atrial electrograms (CFAE) in both atria in patients with paroxysmal and persistent AF. The NavX™ system was used to map the left and(More)
A remote magnetic navigation (MN) system is available for radiofrequency ablation of atrial fibrillation (AF), challenging the conventional manual ablation technique. The myocardial markers were measured to compare the effects of the two types of MN catheters with those of a manual-irrigated catheter in AF ablation. AF patients underwent an ablation(More)
AIMS The recurrence of atrial fibrillation (AF) after pulmonary vein (PV) isolation is still a challenge. We investigated a new approach to treating AF patients by silencing electrical activity in the posterior inter-pulmonary-vein atrium (PIA). METHODS AND RESULTS Three ablation steps are required to obtain PIA electrical silence: electrical PV(More)
BACKGROUND AND STUDY OBJECTIVE Patients with paroxysmal or persistent atrial fibrillation (AF) can be treated by pulmonary vein (PV) isolation. Although the recurrence rate after the procedure is relatively high, the long-term outcomes after initially recurrence-free procedures remains unclear. We examined the rates of recurrence of AF after PV isolation.(More)
AIMS Ventricular arrhythmias arising from the fibrous rings have been demonstrated, but knowledge about the aortomitral continuity (AMC) as a source of the arrhytmias is still limited. The objective is to describe the characteristics of ventricular arrhythmias originating from the AMC in patients without structural heart disease. METHODS AND RESULTS Ten(More)
BACKGROUND Pulmonary vein (PV) isolation is used for the treatment of atrial fibrillation (AF). Complex fractionated atrial electrogram (CFAE) mapping has been introduced to guide AF ablation. However, the spatial relationship between PV and CFAE is not well defined. METHODS AND RESULTS The study included 21 patients (mean age 57 +/- 11 years, 17 men, 14(More)
A 15-year-old boy who had been given an orthotopic heart transplant 12 years earlier underwent radiofrequency ablation after 14 months of tachycardia. At the time of the procedure, the patient presented moderate signs of heart failure and tachycardia-induced cardiomyopathy. During electroanatomical mapping we identified a focal atrial tachycardia with(More)
We investigated the relationship between arrhythmia burden, left atrial volume (LAV) and N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) at baseline and after long-term follow-up of atrial fibrillation (AF) ablation. We studied 38 patients (23 paroxysmal, 6 women, mean age 56 ± 11) scheduled for AF ablation. LAV was calculated on the basis of(More)
