Abstract

In the presence of tricuspid valve intervention, right ventricular lead implantation is associated with the potential risk of tricuspid valve malfunction leading to a tricuspid regurgitation. Few cases have been reported with successful left ventricular pacing via the coronary sinus (CS) after tricuspid valve replacement or repair. In this retrospective study, we present the long-term clinical outcomes of 17 patients who underwent CS lead implantation and left ventricular pacing. Seventeen consecutive patients referred to our institution with an indication of postprocedural pacemaker (PM) implantation after tricuspid valve intervention were retrospectively included in the study. The indication for device implantation in all patients was atrial fibrillation with a symptomatic pause ≥ 3.0 seconds. Thus, all devices implanted were ventricular rate responsive (VVIR). All device implantations were successful and uncomplicated. Mean operation time was 60 ± 8 minutes. Mean fluoroscopy time was 8.3 ± 2.1 minutes. Mean R-wave sensing was 7.5 ± 2.0 mV with a mean slew rate of 2.2 V/s. A mean pacing threshold of 1.9 ± 0.3 V/0.4 ms was accepted as patients were not PM-dependent. The pacing impedance was 743.5 ± 109.71 Ohm. At 2-year follow...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
