Adenosine administration during hybrid atrial fibrillation ablation to test dormant pulmonary vein conduction

Background Adenosine administration after initial pulmonary vein isolation (PVI) reveals dormant conduction and predicts atrial fibrillation (AF) recurrence. Elimination of dormant conduction when present may increase a long-term success rate of AF ablation procedures. There are no studies till date using adenosine to reveal acute reconduction of pulmonary veins (PVs) after ...

Preoperative planning of left-sided valve surgery with 3D computed tomography reconstruction models: sternotomy or a minimally invasive approach?†

OBJECTIVES With the emergence of a new concept aimed at individualization of patient care, the focus will shift from whether a minimally invasive procedure is better than conventional treatment, to the question of which patients will benefit most from which technique? The superiority of minimally invasive valve surgery (MIVS) has not yet been proved. We believe that through better ...

The role of patient's profile and allogeneic blood transfusion in development of post-cardiac surgery infections: a retrospective study

OBJECTIVES We aimed to investigate the association of patient characteristics and allogeneic blood transfusion products in development of post-cardiac surgery nosocomial infections.

Contact forces during hybrid atrial fibrillation ablation: an in vitro evaluation

Purpose Data on epicardial contact force efficacy in dual epicardial–endocardial atrial fibrillation ablation procedures are lacking. We present an in vitro study on the importance of epicardial and endocardial contact forces during this procedure. Methods The in vitro setup consists of two separate chambers, mimicking the endocardial and epicardial sides of the heart. A circuit, ...

Guideline adherence in antithrombotic treatment after concomitant ablation surgery in atrial fibrillation patients

OBJECTIVES We investigated real-life oral anticoagulation (OAC) treatment after surgical ablation and examined its adherence to current recommendations. We also explored factors related to OAC use preoperatively and at follow-up.

Quantitative assessment of cardiac load-responsiveness during extracorporeal life support: case and rationale

We describe a case of a patient assisted by extracorporeal life support, in which we obtained the dynamic filling index, a measure for venous volume during extracorporeal life support, and used this index to assess cardiac load-responsiveness during acute reloading. While reloading, the obtained findings on cardiac pump function by the dynamic filling index were supported by ...

Health-related quality of life after fast-track treatment results from a randomized controlled clinical equivalence trial

Purpose This randomized clinical equivalence trial was designed to evaluate health-related quality of life (HRQoL) after fast-track treatment for low-risk coronary artery bypass (CABG) patients. Methods Four hundred and ten CABG patients were randomly assigned to undergo either short-stay intensive care treatment (SSIC, 8 h of intensive care stay) or control treatment (care as ...

Cost-effectiveness of ablation surgery in patients with atrial fibrillation undergoing cardiac surgery☆

This study was performed to assess the cost-effectiveness of concomitant ablation surgery (AS) compared to regular cardiac surgery in atrial fibrillation (AF) patients over a one-year follow-up. Cost analysis was performed from a societal perspective alongside a prospective, randomised, double-blinded, multicentre trial. One hundred and fifty patients with documented AF were ...

Serial left-ventricular biopsy sampling using a minimally invasive trans-thoracic approach in adult dogs

Myocardial biopsies are an increasingly important tool to unravel the molecular mechanisms of cardiac disease. We evaluate a novel minimally invasive trans-thoracic approach for left-ventricular (LV) intra-mural biopsies, which enables repetitive individual sampling in adult dogs. Forty three generally anaesthesised dogs were studied during sinus rhythm (SR, control) and multiple ...
