conclusions in the children in this study, pacemaker accelerometers failed to meet physiological demands. results basal heart rates, maximal heart rates, and exercise tolerance were significantly lower in the children with pacemakers. age, sex, and body mass index had no effect on the heart rate slope during the exercise test. there was no significant difference between epicardial and endocardi...

reports which describe sick sinus syndrome due to malignant lymphoma have been rare and only eight cases have been reported until now. this is a case of sick sinus syndrome and superior vena cava syndrome secondary to invasion of occult malignant lymphoma of the lung in a 60 years old male. there were no symptoms or signs of malignancy before the first presentation with sick sinus syndrome. pat...

Introduction Left innominate stricture or stenosis after hemocatheter insertion or pacemaker lead insertion is not an uncommon vascular complication. However, spontaneous left innominate venous stricture has not been reported. We present a case with spontaneous left innominate vein stenosis in a patient with history of open heart surgery during pacemaker implantation. Retrograde channel from th...

OBJECTIVES The purpose of this study was to evaluate the need for a permanent pacemaker after transcatheter aortic valve implantation with the CoreValve prosthesis (Medtronic, Inc., Minneapolis, Minnesota) using the new Accutrak delivery system (Medtronic, Inc.). BACKGROUND The need for a permanent pacemaker is a recognized complication after transcatheter aortic valve implantation with the C...

OBJECTIVE To study the potential interactions in patients with endocardial permanent pacemakers and non-thoracotomy implantable cardioverter defibrillator (ICD) systems. DESIGN Case series and cohort study. SETTING Tertiary referral centre. PATIENTS Fifteen consecutive patients with both endocardial pacemakers (12 dual chamber and three single chamber) and non-thoracotomy ICD systems. M...

We report three cases suffering from endocarditis caused by pacemaker lead infection. Because of the long interval beginning from implantation to surgical removal and the large vegetations on the leads, the entire pacemaker system was removed under extracorporeal circulation (ECC). Postoperative courses were uneventful and none of these patients have shown recurrent infection to date. The total...

Cardiac perforation by a pacemaker lead is a rare complication of pacemaker implantation. Presentation can vary from chest pain and shortness of breath to the patient being completely asymptomatic. Diagnosis is usually made by high-resolution computed tomography (HRCT) scan of the chest. Electrocardiograph (EKG) usually shows the absence of a paced rhythm, but it doesn't provide a definitive di...

Central venous stenosis after the insertion of a permanent pacemaker is a well recognized complication. This late complication is encountered when there is a need to change the pacemaker lead or extract it. We describe a young male who had such a complication after many years after right side pacemaker implantation. The lesion was managed percutaneously leading to placement of a new lead from t...

OBJECTIVES This study examined the utility of a novel technique for reuse of thrombosed veins when extracting permanent pacemaker leads via a femoral vein approach. BACKGROUND Although lead extraction permanent pacemaker using a femoral approach has advantages over the subclavian approach, it cannot be used to provide access for a new lead using currently employed techniques. This is importan...

Atrioventricular nodal block (AVB) is a common complication following transcatheter aortic valve replacement (TAVR). The timing of permanent pacemaker (PPM) implantation with respect to conduction disease and recovery not well established. purpose this study determine the optimal PPM for AVB TAVR. Patients were retrospectively reviewed AB by ECG progress note data in electronic medical record T...
