Adenosine testing after second-generation cryoballoon ablation (ATSCA) study improves clinical success rate for atrial fibrillation.

Aims: Adenosine administration after pulmonary vein (PV) isolation using radiofrequency, laser, and cryoablation can cause acute recovery of conduction to the PVs and predict atrial fibrillation (AF) recurrence. This study evaluates whether ablation of dormant potentials post-adenosine administration following second-generation cryoballoon (CB-2G) ablation may improve the success rate for AF.

Methods And Results: In 45 of 90 patients after a waiting period of 30 min, a bolus 15-21 mg of adenosine was administered followed by rapid saline flush.

Electrocardiographic findings in women with a recent history of pre-eclampsia.

Objective: To assess the prevalence of electrocardiographic (ECG) abnormalities after a pregnancy complicated by pre-eclampsia and/or syndrome of hemolysis, elevated liver enzymes and low platelets (PE) and to compare the ECG characteristics, at least six months after pregnancy, between primiparous early-onset PE women with and without recurrent PE.

Design: Longitudinal observational study.

Setting: Tertiary referral centre in The Netherlands from 1996 to 2008.

Cardiac remodelling: concentric versus eccentric hypertrophy in strength and endurance athletes.

Cardiac remodelling is commonly defined as a physiological or pathological state that may occur after conditions such as myocardial infarction, pressure overload, idiopathic dilated cardiomyopathy or volume overload. When training excessively, the heart develops several myocardial adaptations causing a physiological state of cardiac remodelling. These morphological changes depend on the kind of training and are clinically characterised by modifications in cardiac size and shape due to increased load.
