Cryoablation for paroxysmal and persistent AF in patients with structural heart disease and preserved ejection fraction: Clinical outcomes from 1STOP, a multicenter observational project

Background: Pulmonary vein isolation (PVI)is an accepted strategy for paroxysmal atrial fibrillation (PAF)and persistent AF (PerAF)ablation. Limited data are available on outcomes of cryoballoon (CB)PVI in patients with structural heart disease (SHD). The purpose is to assess the clinical efficacy of a single CB-PVI procedure in patients with PAF or PerAF who also have SHD. Methods: From April 2012, 460 AF patients with concomitant SHD underwent CB-PVI and were followed prospectively in the framework of the 1STOP ClinicalService® project. Data on procedural outcomes and long-term freedom from AF recurrence were evaluated. Out of 460 subjects, 282 patients (61%)had PAF and 178 (39%)PerAF. Results: SHD patients were predominantly male (80.9%), old (62.8 ± 8.9 years), with preserved functional capacity (New York Heart Association class >1: 39.4%), high cardioembolic risk (CHA2DS2VASc score ≥2: 69.3%), and conserved left ventricular ejection fraction (56.5 ± 8% LVEF). Both subjects with PAF and PerAF had similar baseline clinical characteristics except for left atrial diameter (43.8 ± 7 vs. 45.7 ± 7 mm)and area (22.9 ± 5.2 vs. 25.1 ± 4.4 cm2), respectively. Procedure time and fluoroscopic time as well as the rate of procedural complications were not different between subjects with PAF and PerAF. After a mean follow-up of 12 months, antiarrhythmic drug therapy had dropped from 71.7% before ablation to 33.6% post-ablation (p < 0.001)and the freedom from symptomatic AF recurrence was 78% for PAF and 77% for PerAF (p = 0.793). Furthermore, atrial arrhythmia recurrence rate was not related to SHD. Conclusions: In a large multicenter, real-world cohort, CB-PVI was used to treat patients with PAF and PerAF who also had SHD. The arrhythmia recurrence after a single procedure was not related to either the degree of cardiac structural remodeling or the type of AF, and the rate of AF recurrence was lower than previously reported in patients with SHD in other cohort series using focal radiofrequency catheter ablation.

Is the time between first diagnosis of paroxysmal atrial fibrillation and cryoballoon ablation a predictor of efficacy?

Aims Cryoablation is an indicated therapy for the treatment of recurrent atrial fibrillation through pulmonary vein isolation; however, the optimal time between first diagnosis of atrial fibrillation and cryoablation is still unknown. We aimed to assess the clinical efficacy and safety of early versus later treatment of patients with paroxysmal atrial fibrillation by cryoablation. Methods Five hundred and ten patients underwent atrial fibrillation cryoablation and were prospectively followed for at least 6 months in 43 Italian cardiology centers. The population was divided into two groups according to the time since the first diagnosis of atrial fibrillation until the index cryoablation procedure. An early-treatment group had an elapsed time of 15 months or less from atrial fibrillation diagnosis until cryoablation, and the late-treatment group had an elapsed time of greater than 15 months. During the evaluation, clinical efficacy was defined as atrial fibrillation recurrence outside a landmark 90-day blanking period, and safety was defined as the reporting of all procedure-related complications. Results In the total cohort, cryoablation was performed after a median of 36 months from the point of the patient diagnosis with drug refractory symptomatic recurrent atrial fibrillation. The early-treatment group was composed of 130 (25%) patients, whereas the late-treatment group had 380 (75%) patients. Both cohorts had similar baseline clinical characteristics. Of 510 patients, 22 had a complication related to the procedure with no difference between the two groups. Multivariable analysis showed that the risk of atrial fibrillation recurrence was significantly higher in the late-treatment group (hazard ratio: 1.77; 95% confidence interval 1.00-3.13) Conclusion In our multicenter observational examination, cryoablation was well tolerated and effective in the treatment of patients with drug refractory symptomatic paroxysmal atrial fibrillation. Reducing the time between diagnosis and ablation brought about a treatment that had a lower risk of atrial fibrillation recurrence with no change in safety.

Long-term outcomes after prophylactic ICD and CRT-D implantation in nonischemic patients: Analysis from a nationwide database of daily remote-monitoring transmissions

Introduction: Clinical trials did not provide conclusive evidence concerning the benefit of prophylactic implantable cardioverter-defibrillators (ICDs) in patients with severe nonischemic cardiomyopathy (NICM). We aimed to compare incidence of appropriate sustained ventricular arrhythmia (SVA) and device therapy in ischemic cardiomyopathy (ICM) vs NICM ICD and/or cardiac resynchronization therapy (CRT-D) patients. Methods and Results: We analyzed remote-monitoring data from devices of the Home Monitoring Expert Alliance network. SVA recordings were adjudicated by three independent electrophysiologists. Our cohort included 1,946 patients who received either an ICD (55%) or a CRT-D (45%) for primary prevention of sudden cardiac death. Median (interquartile range) age was 70 (62-77) years, 81% were male, and 52% were in the ICM group. Patients were remotely monitored for a maximum follow-up of 5 years. The 5-year product-limit estimate of SVA incidence in patients with an ICD was 47.3% (95% confidence interval [CI], 41.0%-53.9%) in the ICM group and 44.7% (36.9%-53.3%) in the NICM group. In patients with a CRT-D, SVA incidence was 45.7% (37.3%-55.0%) in ICM patients and 49.2% (40.4%-58.7%) in NICM patients. The adjusted hazard ratio for SVA in the ICM vs NICM group was 0.96 (95% CI: 0.70-1.30, P =.77) in ICD patients and 0.85 (95% CI: 0.61-1.18, P =.34) in CRT-D patients. SVAs triggered appropriate device therapies with similar incidence in all groups. Conclusion: In a large cohort of remotely monitored ICD and CRT-D recipients, SVA incidence did not significantly differ in ICM and NICM patients

Itraconazole oral solution as prophylaxis for fungal infections in neutropenic patients with hematologic malignancies: a randomized, placebo-controlled, double-blind, multicenter trial. GIMEMA Infection Program. Gruppo Italiano Malattie Ematologiche dell' Adulto.

To evaluate the efficacy and safety of itraconazole oral solution for preventing fungal infections, a randomized, placebo-controlled, double- blind, multicenter trial was conducted: 405 neutropenic patients with hematologic malignancies were randomly assigned to receive either itraconazole, 2.5 mg/kg every 12 hours (201 patients), or placebo (204 patients). Proven and suspected deep fungal infection occurred in 24% of itraconazole recipients and in 33% of placebo recipients, a difference of 9 percentage points (95% confidence interval [CI], 0.6% to 22.5%; P = .035). Fungemia due to Candida species was documented in 0.5% of itraconazole recipients and in 4% of placebo recipients, a difference of 3.5 percentage points (95% CI, 0.5% to 6%; P = .01). Deaths due to candidemia occurred in none of the itraconazole recipients compared with 4 placebo recipients, a difference of 2 percentage points (95% CI, 0.05% to 4%; P = .06). Aspergillus infection was documented in four itraconazole recipients (one death) and one placebo recipient (one death). Side effects causing drug interruption occurred in 18% of itraconazole recipients and 13% of placebo recipients. Itraconazole oral solution was well-tolerated and effectively prevented proven and suspected deep fungal infection as well as systemic infection and death due to Candida species
