Surgical Implantation of Endocardial Lead for Adult Congenital Atrioventricular Block Combined with Obstructed Bilateral Subclavian Vein

Occlusion of the proximal subclavian vein complicating pacemaker lead implantation.

A set of images in which a pacemaker lead replacement procedure was complicated by occlusion of the proximal subclavian vein is presented. However, this was not detected on venography performed before the procedure. Physicians should be aware of a more proximal occlusion of the subclavian vein while replacing pacemaker leads, even in cases with seemingly normal venography.

Pacemaker implantation in a premature low weight newborn with critical congenital atrioventricular block.

We describe a case of a preterm newborn with congenital complete atrioventricular block (CAVB), delivered for distress by cesarean section, and undergone, at 1295 grams of weight, to permanent pacemaker implantation. The pacemaker has been inserted between the upper left rectus abdominal muscle and the posterior rectus sheath and connected by two epicardial leads on the left ventricle wall. The...

Antenatal and postnatal combined therapy for autoantibody-related congenital atrioventricular block

BACKGROUND Autoantibody-related congenital heart block (CHB) is an autoimmune condition in which trans placental passage of maternal autoantibodies cause damage to the developing heart conduction system of the foetus. CASE PRESENTATION We report a case of an Italian 31-year-old woman, in a good clinical status, referred to our Centre at 26 weeks of her first pregnancy, because of foetal brady...

Sinus 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...
