Failure of cardiac antiarrhythmic ablation to block action potential conduction produces poor outcomes which lead to repeat procedures. To overcome this, an intraoperative index of the quality of an ablation lesion is needed. We hypothesized that a r

Cardiac action potentials have been measured with single-photon excitation (SPE) of transmembrane voltage-sensitive fluorescent dye. Two-photon excitation (TPE) may have advantages for localization and depth of the tissue region from which the action

Development of antiarrhythmic electrical therapies requires knowledge of the characteristics of cardiac arrhythmias and effects of electrical stimulation on the heart. Much of the available knowledge is obtained from measurements of extracellular pot

Production of complete (i.e. continuous and transmural) cardiac lesions by radiofrequency (RF) ablation can cure certain cardiac arrhythmias. However, a predictor of lesion completeness that is reliable and can be measured intraoperatively is needed

Major effects of stimulation on cardiac transmembrane potentials (Vm) are thought to occur under the electrode, however these have not been optically mapped due to blockage of light by electrodes. Here we optically mapped under translucent indium tin

• A 48-year-old woman with known Ebstein's anomaly had bilateral, lower-extremity arterial emboli after a total abdominal hysterectomy. She underwent embolectomy, placement of a Greenfield caval filter, subsequent tricuspid valve replacement, and c
