Left ventricular electromechanical mapping in stunned myocardium.
A62-year-old woman with a history of vasospastic angina presented to the emergency room with chest pain. The ECG showed ST-segment elevation in leads V3 through V6. The transthoracic echocardiogram revealed an akinetic left ventricular (LV) apical wall. The coronary angiogram on admission demonstrated normal coronary arteries. Two weeks later, resting Tc-tetrofosmin myocardial single photon emi...
متن کاملLeft ventricular electromechanical mapping to assess efficacy of phVEGF(165) gene transfer for therapeutic angiogenesis in chronic myocardial ischemia.
BACKGROUND NOGA left ventricular (LV) electromechanical mapping (EMM) can be used to distinguish among infarcted, ischemic, and normal myocardium. We investigated the use of percutaneous LV EMM to assess the efficacy of myocardial gene transfer (GTx) of naked plasmid DNA encoding for vascular endothelial growth factor (phVEGF(165)), administered during surgery by direct myocardial injection in ...
متن کاملComparison between left ventricular electromechanical mapping and radionuclide perfusion imaging for detection of myocardial viability.
BACKGROUND A novel 3-dimensional left ventricular (LV) mapping system uses low-intensity magnetic field energy to determine the location of sensor-tipped electrode catheters within the LV. Using this system, we sought to distinguish between infarcted, ischemic, and normal myocardium by comparing LV electromechanical mapping data with myocardial perfusion imaging studies. METHODS AND RESULTS U...
متن کاملLeft Ventricular Electromechanical Mapping for Determination of Myocardial Function and Viability*
Left ventricular electromechanical mapping (LVEMM, also termed NOGA or Biosense procedure) is derived from a diagnostic and navigational guidance tool that utilizes ultralow magnetic-field sources and location sensor-tipped catheter electrodes that trace the catheter-tip position in three-dimensional (3D) space (1–3). The system reconstructs electromechanical maps of the left ventricle with min...
متن کاملMyocardial ischemia with left ventricular outflow obstruction
We report an unusual case of a 32-year old man who was treated for a hypertrophic obstructive cardiomyopathy (HOCM) with a DDD pacing with short AV delay reduction in the past. Without prior notice the patient developed ventricular fibrillation and an invasive cardiac diagnostic was performed, which revealed a myocardial bridging around of the left anterior descending artery (LAD). We suspected...
