Atrial Fibrillation Data From UK Study Evaluating the Cardima EP Ablation System

FREMONT, CA--(Marketwire - June 12, 2008) - Cardima, Inc. (OTCBB: CADM) -- Leading Electrophysiology Physicians at Guy's and St. Thomas Hospital, London, UK, have concluded a portion of a study for the treatment of Atrial Fibrillation ("AF"). Guy's and St. Thomas Hospital is a leading cardiac center located in the center of London, England. Patients with both paroxysmal and persistent AF were included in this trial. Cardima's EP Ablation System is being used to treat the patients. To date, Guy's and St. Thomas Hospital has treated over 110 AF patients using the Cardima System.

This UK single center study is on-going, and to date, 30 patients have completed the follow-up monitoring necessary to define success. The principal investigator of the study, Jaswinder Gill MD, FRCP, recently compiled this data on the first 30 patients and presented it at the Fourth Annual Congress of the European Cardiac Arrhythmia Society (ECAS) in Marseille, France on April 13-15th, 2008. His abstract, titled: "Performance of a Novel Linear Catheter Ablating System for Left and Right Atrial Compartmentalization to Reproduce MAZE Operation" has also been accepted for publication by the Journal of Interventional Cardiology and Electrophysiology ("JICE") and is included in Volume 22:1, 2008.

In commenting on his study, Dr. Gill stated: "This early patient data demonstrates that the Cardima EP Ablation System is safe for use in the left atrium. It also illustrates how the Cardima catheter, the REVELATION® T-Flex, can be used to create lesions in the left and right atrium that mimic the Cox Maze for the treatment of AF in a safe and effective manner. Our team looks forward to working with Cardima to expand our study and build a robust body of data that will assist in establishing this linear ablation system as a safe and effective tool for the treatment of AF. Identifying new patient treatment options for AF that are safe and effective is an important public health issue for the UK and many countries around the world."

Cardima's CEO, Robert Cheney, acknowledged the important contribution by Dr. Gill and the team at Guy's and St. Thomas Hospital, "Cardima is very proud to be associated with Guy's and St. Thomas Hospital, a leader in cardiac care, and the highly professional team led by Dr. Gill. The data presented will benefit patients across the UK and the European Union who are in need of AF treatment. We look forward to working with Dr. Gill and his team to expand this study to more centers in the UK over the coming months."
