Introduction A 75-year-old woman with a dual-chamber pacemaker was seen in the cardiology clinic for possible device malfunction. The patient’s device identification card revealed that a pacemaker from “Manufacturer A” was implanted in 2001. However, device interrogation using the corresponding programmer failed to communicate with the device. Given the age of the device, complete depletion of ...

INTRODUCTION AND OBJECTIVES Although changes in atrioventricular conduction frequently occur after percutaneous implantation of an aortic valve prosthesis, little is known about the mechanisms involved or how these changes progress. We investigated ECG abnormalities and predictors of pacemaker need after percutaneous implantation of the CoreValve® aortic valve prosthesis. METHODS Between Apri...

We report the case of a 35-yr-old patient who presented with high fever and chills. He had undergone a patch closure of the ventricular septal defect 18 yr before. One year later, a VVI pacemaker was implanted via the right subclavian vein because of complete heart block. Nine years after that, a new VVI pacemaker with another right ventricular electrode was inserted controlaterally and the old...

The challenge of this treatment lies in the comprehensive follow up of the device. As the number of implanted devices...

In 2014, an 84-year-old man with pacemaker erosion was referred to our center. He underwent coronary artery bypass graft surgery in 2008 for multivessel coronary artery disease. In 2009, he developed sick sinus syndrome and received a Biotronik Cylos 990 DR-T DDD pacemaker with a 7.2-F Biotronik Selox SR 53 active fixation atrial lead and a 4.8-F Sorin Xfine TX26D passive ventricular lead. In J...

Severe and permanent tricuspid regurgitation induced by pacemaker leads is rarely reported in the literature. The mechanism of pacemaker-induced tricuspid regurgitation has been identified, but its management has not been well established. Furthermore, debate still exists regarding the proper surgical approach. We present the case of a patient with severe tricuspid regurgitation induced by a pa...

Ventricular inhibited cardiac pacemakers were suppressed by intimate contact of the tip of the active pacemaker electrode with that of the inactive pacemaker electrode in two patients. This contact apparently was sensed as myocardial electrical activity and resulted in variable suppression of pacemaker emission. There was no interference with R-wave sensing function. The threshold for stimulati...

Oblivious manipulation of the device by the patient is referred to as "Twiddler's" syndrome. It is characterized by the coiling of the pacemaker lead due to the rotation of the pacemaker generator on its long axis. However, the rotation of the pacemaker generator on its transverse axis with subsequent coiling of the pacemaker leads around the pulse generator is called as ''Reel syndrome''. In t...

Ellis-van Creveld syndrome is transmitted as an autosomal recessive trait. This syndrome is accompanied in 60% of cases with congenital heart disease, mostly single atrium or large ASD. Patients are mostly symptomatic, but in this rare case despite 68 years of age, the patient was free of symptoms except for complete heart block for which pacemaker was inserted

This case describes an iatrogenic cause of heart failure: the pacemaker syndrome. The diagnosis was initially overlooked but in retrospect could have easily been made by reviewing the rhythm strip recorded during the echocardiogram. The patient eventually received the correct treatment to restore atrioventricular synchrony and experienced rapid resolution to her disabling symptoms. LEARNING P...
