MTWA Testing Would Lead To More ICD Referrals – Medtronic
This article was originally published in The Gray Sheet
Executive Summary
Medtronic is sponsoring a registry to help determine whether microvolt T-wave alternans (MTWA) testing can identify post-MI patients with a left-ventricular ejection fraction (LVEF) of 30%-40% who are most likely to benefit from an ICD

T-Wave
ABCD trial comparing Cambridge Heart's Heartwave microvolt T-wave alternans (MTWA) system to standard invasive electrophysiology tests for sudden cardiac death risk completes enrollment, sponsor St. Jude Medical announces Sept. 13. The 540-patient trial began in 2001. St. Jude is sponsoring the trial because "the availability of a proven, non-invasive test for this at-risk group may help more patients receive life-saving implantable cardioverter defibrillator therapy," St. Jude VP-Cardiac Rhythm Management Regulatory Affairs Eric Fain explains in a release. Medtronic offers a similar justification for its MASTER trial of the Heartwave system (1"The Gray Sheet" July 14, 2003, p. 32)...

Heartwave II
FDA clears Cambridge Heart's third-generation Microvolt T-wave Alternans sudden cardiac death risk diagnostic system, the firm says April 11. Unlike previous versions of the system, Heartwave II can complete all of the elements of a MTWA test and does not require a host stress exercise system to control the treadmill during the stress-test portion of the diagnostic procedure. Medtronic is co-sponsoring an MTWA registry to help determine whether the test can identify post-MI heart failure patients most likely to benefit from an implantable cardioverter defibrillator (1"The Gray Sheet" July 14, 2003, p. 32)...
