Biventricular pacing in the early postoperative period after cardiac surgery.
Cardiac resynchronization therapy is not commonly used in the early postoperative period in patients undergoing cardiac surgery who have left ventricular (LV) dysfunction and a history of heart failure. We performed a prospective randomized clinical trial to compare atrial synchronous right ventricular (DDD RV) and biventricular (DDD BIV) pacing within 72 hours after cardiac surgery in patients...
متن کاملCardiac Resynchronization Therapy; Biventricular Pacing
Although the estimates from limited studies vary on the proportion of patients with heart failure who also have ventricular dyssynchrony as reflected by a prolonged QRS complex, often in the form of left bundle branch block, the number of such patients is large (27% to 53%) and it is certainly in excess of the rate for the general population. Among these patients, 10% to 15% are candidates for ...
متن کاملProgression of heart failure in right univentricular pacing compared to biventricular pacing.
BACKGROUND Cardiac resynchronization therapy (CRT) improves hemodynamics and symptoms of heart failure by reducing ventricular dyssynchronity. Conversely, recent studies have demonstrated that right univentricular pacing in patients with an ejection fraction below 40% aggravates heart failure. In this retrospective study, we compared progression of disease in patients with mild to moderate hear...
متن کاملImproving cardiac function after cardiac surgery by biventricular pacing in patient selected by three-dimensional echocardiography.
We present the case of a 57-year-old woman with severe aortic regurgitation and ventricular dysfunction (ejection fraction 34%) requiring surgical intervention. In pre-operative period, no left ventricular (LV) asynchrony was detected by QRS duration and current echocardiographic techniques, including tissue Doppler imaging. A new echocardiographic technology, the timing of regional volumetric ...
متن کاملA Review of Temporary Cardiac Pacing Wires
AIMS This review aims to tabulate data from all available studies of temporary cardiac pacing wires. Particular aims were to determine the best route of venous access and find ways to reduce complications. The review set out to see if specialist doctors are better at inserting wires than non-specialist doctors. In addition, a contemporary study of wire insertion has been performed to compare mo...
