RESUMO
BACKGROUND: Elderly patients with atrial septal defect (ASD) often present with chronic atrial fibrillation and large left to right shunt. This study reports the experience of left atrial appendage (LAA) and ASD closure in patients with significant ASD and chronic atrial fibrillation. METHODS: We report six consecutive elderly patients with chronic atrial fibrillation and significant ASD who underwent LAA and fenestrated ASD closure from January 1, 2014 until December 31, 2019. All periprocedural and long-term (>1 year) outcomes were reported. RESULTS: Six patients (male: 33.3%; mean age: 66.8 ± 3.3 years) were included. Mean CHADS2 , CHA2 DS2 -VASc , and HAS-BLED scores were 2.33 ± 0.82, 3.83 ± 0.75, and 1.83 ± 0.75. Four patients underwent simultaneous procedure, while two patients underwent a staged procedure. Procedural success was achieved in all patients. Total occlusion was achieved during LAA occlusion without device embolization prior to ASD closure. Patients who underwent simultaneous procedure had a shorter total hospital stay and lower total hospital stay. During a follow-up period of 32.8 ± 19.4 months, both the devices were well seated. No device-related thrombosis or erosion reported. All patients remained in atrial fibrillation. No patients experienced any thromboembolic stroke or transient ischemic attack. CONCLUSIONS: LAA and ASD closure is feasible and can be safely performed in the same seating in elderly patients with a significant ASD.

BACKGROUND: Cryoballoon ablation is a commonly used approach to treat patients with atrial fibrillation (AF). OBJECTIVES: Report on the safety and efficacy of cryoballoon ablation for the treatment of AF in the largest global cohort of cryoablated patients prospectively studied within a single registry. METHODS: The Cryo AF Global Registry is a prospective, multi-center registry. Patients with paroxysmal AF (PAF) or persistent AF (PsAF) were treated with the cryoballoon catheter according to routine practices at 93 sites across 36 countries. Primary efficacy endpoints included freedom from AF and freedom from AF/atrial flutter (AFL)/atrial tachycardia (AT) ≥30 seconds. The primary safety endpoint was serious device- or procedure-related adverse events over 12 month follow-up. RESULTS: During this evaluation window, 2922 subjects completed an index cryoballoon procedure, and 1440 completed 12 month follow-up. The cohort was 61 ± 12 years of age, 36.3% female, and 78.7% PAF. Serious device- and procedure-related adverse event rates were 1.5% and 3.4%, respectively. Freedom from AF/AFL/AT after the 90 day blanking period was 86.4% (95% CI: 84.3%-88.3%) in patients with PAF and 70.9% (95% CI: 64.6%-76.4%) in patients with PsAF. Freedom from AF/AFL/AT in first-line PAF and PsAF was 90.0% (95% CI: 86.4%-92.7%) and 72.9% (95% CI: 58.6%-83.0%) at 12 months, respectively. CONCLUSIONS: The Cryo Global AF Registry is the largest evaluation to demonstrate cryoablation is an efficient, safe, and effective treatment for patients with AF worldwide. Cryoablation was commonly used to treat patients prior to an AAD failure and may facilitate earlier therapy for patients on the AF disease continuum.
