HINOJOS A, ILG K. Removal of Misplaced Left Ventricular Single Lead Pacemaker in a Patient Presenting with Recurrent Transient Ischemic Attacks. Spartan Med. Res. J. Vol. 2, No. 1, pp. 64-73, 2017. CONTEXT: Over 200,000 cardiac electronic implantable devices are annually placed in individuals living within the United States. Complications from this procedure can range up to 12%. Inadvertent lead placement into the left ventricle is a rare but recognized complication of implantable cardiac electronic devices. METHODS: This is a retrospective case report of a female patient in her late 70’s who underwent atrioventricular node ablation and misplacement of single lead pacemaker, subsequently presenting with recurrent transient ischemic attacks one month later. RESULTS: Initial electrocardiogram and chest X-ray demonstrated misplacement of her pacemaker in the left ventricle. Medical therapy was attempted, however, patient subsequently underwent extraction via aortotomy with implantation of epicardial pacemaker. CONCLUSIONS: Inadvertent placement of implantable electronic cardiac devices is a rare but well recognized complication. A post-procedure electrocardiogram and chest X-ray should be routinely performed to confirm appropriate lead placement. Procedures to manage this complication are evolving with novel device therapies specifically designed for percutaneous lead extraction.

An Unusual Cause of Transient Ischemic Attack in a Patient with Pacemaker
Pacemaker lead malposition in various locations has been described in the literature. Lead malposition in left ventricle is a rare and an underdiagnosed complication. We present a 77-year-old man with history of atrial fibrillation and pacemaker placement who was admitted for transient ischemic attack. He was on aspirin, beta blocker, and warfarin with subtherapeutic international normalized ra...

Lead induced transient right bundle branch block is not uncommon during pacemaker implantation. We describe a patient with old anterior wall myocardial infarction with severe left ventricular dysfunction presenting with recurrent ventricular tachycardia who developed transient right bundle branch block and pseudomyocardial infacrction pattern during AICD implantation.

Transient ischemic left ventricular dilation (TID) is a marker of severe and extensive coronary artery disease as well as an increased risk of adverse outcomes. The patients with more severe and extensive ischemia, multivessel-type of perfusion abnormality as well as patients with left anterior descending artery (LAD) territory perfusion abnormality have more probab...

A 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. He finally was diagnosed as having Twiddler's syndrome. The patient had a pulse rate of 36/min and cannon waves in the neck veins. Chest radiography showed a dislodged pacing lead completely wrapped around the pulse...

BACKGROUND Calcific deposits are frequently observed at sites of healed myocardial infarcts. Grossly visible calcification of myocardial infarcts and calcified intracavitary cardiac thrombi are less common but recently are becoming more frequent findings during surgical ventricular restoration procedures. CASE PRESENTATION A 64 year old male diabetic patient experienced two episodes of transi...
