Costs and long-term outcomes following pulmonary vein isolation for atrial fibrillation in elderly patients using second-generation cryoballoon vs. open-irrigated radiofrequency in China.

J Interv Card Electrophysiol 2020 Dec 31;59(3):557-564. Epub 2019 Dec 31.

Department of Cardiology, Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine, #261 Huansha Road, Hangzhou, 310000, Zhejiang Province, China.

Purpose: Limited comparative data are available regarding catheter ablation (CA) of atrial fibrillation (AF) using second-generation cryoballoon (CB-2) vs. radiofrequency (RF) ablation in elderly patients (> 75 years old). The present study aimed to compare the costs and clinical outcomes in elderly patients using these two strategies. Read More

Predictors of Short and Long Term Recurrences of Paroxysmal AF after Radiofrequency Ablation. Is Blanking Period Really Benign?

J Atr Fibrillation 2018 Dec 31;11(4):2012. Epub 2018 Dec 31.

Cardiology department, Ain shams university, Cairo, Egypt.

Background: Following pulmonary vein isolation for paroxysmal atrial fibrillation (PAF), early recurrences of atrial arrhythmias (ERAA) are frequent, classified benign as a part of a blanking period. But recently it seems that there is increased incidence of late recurrences in patients with ERAA but mechanism is still unknown.

Purpose: To assess the incidence and risk factors for early and late AF recurrences post AF ablation and the impact of these ERAA on long-term success. Read More

Usefulness of Failed Electrical Cardioversion for Early Recurrence After Catheter Ablation for Atrial Fibrillation as a Predictor of Future Recurrence.

Am J Cardiol 2019 03 4;123(5):794-800. Epub 2018 Dec 4.

Department of Cardiology, Sakurabashi Watanabe Hospital, Osaka, Japan. Electronic address:

Early recurrence of atrial arrhythmia (ERAA) during a blanking period after catheter ablation (CA) for atrial fibrillation (AF) does not always result in subsequent AF recurrence. We investigated whether failed electrical cardioversion (ECV) during the blanking period was associated with recurrence. A total of 1,240 consecutive patients who underwent first-time CA for AF at our institution between March 2012 and March 2016 were investigated. Read More

Clinical significance of the timing of early recurrence of atrial arrhythmia after pulmonary vein isolation: a two-institution clinical study.

Heart Vessels 2019 May 2;34(5):842-850. Epub 2018 Nov 2.

Department of Cardiology, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-ku, Nagoya, Aichi, 466-8550, Japan.

Early recurrence of atrial arrhythmia (ERAA) after ablation frequently occurs, but there is limited evidence about ERAA-timing. This study aimed to investigate the association between ERAA-timing and late recurrence. We retrospectively investigated 332 patients who underwent PVI for paroxysmal atrial fibrillation at Nagoya University Hospital and Komaki City Hospital. Read More

Early recurrence of atrial arrhythmias following pulmonary vein antral isolation: Timing and frequency of early recurrences predicts long-term ablation success.

Heart Rhythm 2015 Dec 14;12(12):2461-8. Epub 2015 Jul 14.

Cardiovascular Division, Electrophysiology Section, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania. Electronic address:

Background: Early recurrence of atrial arrhythmia (ERAA) is common after atrial fibrillation (AF) ablation and is associated with long-term recurrence. However, the association between timing or frequency of ERAA and long-term ablation success remains unclear.

Objective: We aimed to examine whether timing or frequency of ERAA after pulmonary vein antral isolation (PVAI) affects long-term ablation success. Read More

Sorting, recognition and activation of the misfolded protein degradation pathways through macroautophagy and the proteasome.

Autophagy 2008 Feb 19;4(2):141-50. Epub 2007 Oct 19.

Department of Pathology, University of Pittsburgh School of Medicine, Pittsburgh, Pennsylvania 15231, USA.

Based on a functional categorization, proteins may be grouped into three types and sorted to either the proteasome or the macroautophagy pathway for degradation. The two pathways are mechanistically connected but their capacity seems different. Macroautophagy can degrade all forms of misfolded proteins whereas proteasomal degradation is likely limited to soluble ones. Read More
