Restoration of atrial contractility after surgical cryoablation: clinical, electrical and mechanical results.

To assess the electrical sinus rhythm (SR) recovery and the mechanical effectiveness of the atrial contraction by echocardiography is essential in patients undergoing atrial fibrillation (AF) surgery. Between September 2006 and May 2008, patients with chronic AF (n=33; permanent=23 or paroxysmal=10) underwent mitral surgery and surgical cryoablation for AF. Exclusion criteria were: AF that has persisted for 10 years and left atrium (LA) >65 mm.

[Bloodless cardiac surgery in Jehovah's witnesses: outcomes compared with a control group].

Introduction And Objectives: Some patients, such as Jehovah's Witnesses, refuse to use blood products, which can make it difficult to achieve the same outcomes as in the general population. The objective of this study was to determine whether clinical characteristics and surgical outcomes in Jehovah's Witnesses undergoing cardiac surgery are similar to those in other patients.

Methods: Paired-group retrospective cohort study.
