Background: The literature data on the outcomes of radiofrequency catheter ablation for atrial fibrillation (AF) in women are contradictory.
Aim: To determine and compare the outcomes and complications of cryoballoon pulmonary vein isolation (cryo-PVI) in men vs. women, and to identify predictors of atrial tachyarrhythmia (ATa) recurrence.
Background: There is no consensus on the most effective radiofrequency ablation strategy for the initial or repeated treatment of persistent atrial tachyarrhythmia (ATa).
Objective: To describe success and complication rates after the creation of left atrial (LA) linear lesions for recurrent persistent ATa following an index cryoballoon pulmonary vein isolation (PVI), and to identify predictors of ATa recurrence.
Methods: During March 2013 to March 2020, we prospectively included all consecutive patients undergoing repeat procedures for the treatment of persistent ATa.
Article Synopsis
- Cryoballoon pulmonary vein isolation (PVI) is gaining popularity for treating persistent atrial fibrillation (AF), and this study analyzed its effectiveness and recurrence rates after the procedure.
- Out of 399 patients treated, 90% completed a 12-month follow-up, revealing a 2-year freedom from arrhythmia at 51% for persistent AF and 27% for long-standing persistent AF.
- Key predictors for recurrence included long-standing persistent AF and the size of the left atrial area/volume, with complications being rare (only a few cases of serious side effects).
Background: Most cases of left-sided native valve infective endocarditis (IE) involve a single valve and little is known concerning IE that simultaneously affects the aortic and mitral valves.
Methods: We aimed to determine the characteristics, identify the prognostic factors, and define the effect of early surgery for patients with left-sided native bivalvular IE. This analysis included 1340 consecutive patients who presented with definite acute left-sided native valve IE in a 2-centre cohort study.
Objective: The primary objective was to assess the characteristics and prognosis of pyogenic spondylodiscitis (PS) in patients with infective endocarditis (IE). The secondary objectives were to assess the factors associated with occurrence of PS.
Methods: Prospective case-control bi-centre study of 1755 patients with definite IE with (n=150) or without (n=1605) PS.
