Simultaneous atrioventricular node ablation and leadless pacemaker implantation☆☆☆
Introduction The ablate-and-pace technique is a well-established method to treat patients with persistent and paroxysmal atrial fibrillation with poor rate control on medical therapy.1 The technique represents a class IIa indication to control heart rates when pharmacologic therapy is insufficient or intolerable.2 As many of these patients are in permanent atrial fibrillation, they frequently r...
متن کاملSinus Node Dysfunction Requiring Permanent Pacemaker Implantation in a Young Adult with Klinefelter Syndrome
BACKGROUND Klinefelter syndrome is the most common genetic cause of male infertility and affects approximately 1 in 500 live births. Although accompanying cardiac disorder is not a specific feature of Klinefelter syndrome, rarely associated anomalies such as mitral valve prolapse, atrial septal defect, ventricular septal defect, tetralogy of Fallot, patent ductus arteriosus, and hypertrophic ob...
متن کاملSinus node function in children with congenital complete atrioventricular block.
AIMS Children with congenital complete atrioventricular block (CCAVB) often need pacemaker therapy. In these children, it may be preferable to use single-lead VDD pacing, but for VDD pacing a normal sinus node function is required. Our aim was to study sinus node function in children with CCAVB. METHODS AND RESULTS We longitudinally evaluated sinus rate in 36 children with CCAVB and normal an...
متن کاملTransient atrioventricular block following catheter radiofrequency sinus node modification.
Complete atrioventricular block, second-degree Mobitz type II and first-degree atrioventricular block with right bundle branch block were observed consecutively following successful radiofrequency ablation in close proximity to the sinus node. This resulted in the modification and disappearance of the inappropriate sinus tachycardia that had previously been present. Neither tachycardia nor cond...
متن کاملPacemaker channel dysfunction in a patient with sinus node disease.
The cardiac pacemaker current I(f) is a major determinant of diastolic depolarization in sinus nodal cells and has a key role in heartbeat generation. Therefore, we hypothesized that some forms of "idiopathic" sinus node dysfunction (SND) are related to inherited dysfunctions of cardiac pacemaker ion channels. In a candidate gene approach, a heterozygous 1-bp deletion (1631delC) in exon 5 of th...
