http://www.or-live.com/mercyHospital/1790 Heart Disease: ??? Mercy Hospital's Dr. Alberto Interian, medical director of the Arrhythmia Syncope Center, will present an Electrophysiological Study and Catheter Ablation with 3-D Mapping during a live webcast on November 15th at 5:00 p.m. This will be the first time a procedure of this kind is performed live during a web broadcast and simulcast in English and Spanish. An electrophysiology (EP) test or study looks at the electrical system of the heart by recording the electrical activity from within the chambers of the heart. Thin catheters are advanced into the heart through a small tube similar to cardiac catheterization to see if the irregular heartbeat can be reproduced. An EP study allows the electrophysiologist to study heart rhythm disturbances (arrhythmias) in a controlled setting. The procedure is typically performed when a patient has a pre-determined abnormality such as supraventricular or ventricular tachycardia (SVT or VT). After the mapping has been completed, the ablation can be performed. During the ablation, radiofrequency energy is delivered through a catheter that is in contact with the abnormal pathway or focus. The tip of the catheter heats up and eliminates the abnormal pathway or focus. Dr. Interian will perform the procedure as part of Mercy Hospital's program to broadcast select surgeries and special procedures on the web so individuals can log on and view what takes place in the operating room during those procedures. Mercy initiated this program with hopes of minimizing the fear and anxiety patients feel prior to undergoing a surgery or procedure. The procedure will be the 5th webcast that Mercy Hospital broadcasts live on the web. Mercy Hospital, a recipient of the prestigious Magnet??? award for nursing excellence, is Miami-Dade's only Catholic Hospital. Established in 1950, it is sponsored by the Sisters of St. Joseph and a member of Catholic Health East. A 483-bed acute care hospital,...
