Implantation took 19 minutes (22%) longer in the electrical (104 minutes) versus imaging (85 minutes) group with no increase in complications. There were no differences between groups in left ventricular reverse remodelling, New York Heart Association functional class, six minute walk test, and quality of life.
Principal investigator Dr Charlotte Stephansen, of Aarhus University Hospital, Denmark, said: “Increased left ventricular ejection fraction after CRT is associated with a better prognosis. The 4% greater increase in the electrical group is of a magnitude shown to improve functional response and cardiac event-free survival in previous studies,4-6 indicating that the improvement is clinically important.”
The Danish-CRT trial, set to enrol 1,000 patients, is testing whether electrically guided positioning of the left ventricular lead reduces hospitalisation for heart failure or death compared to standard of care lead placement.
About the European Heart Rhythm Association
The European Heart Rhythm Association (EHRA) is a branch of the European Society of Cardiology (ESC). Its aim is improving the quality of life and reducing sudden cardiac death by limiting the impact of heart rhythm disturbances. EHRA ensures the dissemination of knowledge and standard setting; provides continuous education, training and certification to physicians and allied professionals involved in the field of cardiac arrhythmias with a special focus on Atrial Fibrillation (AF) and Electrophysiology (EP).
About the EHRA Congress
EHRA 2019 is the annual congress of the European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC).
About the European Society of Cardiology
The European Society of Cardiology brings together health care professionals from more than 150 countries, working to advance cardiovascular medicine and help people lead longer, healthier lives.
