Heart Failure Quality Indicators
Device Therapy
Cardiac resynchronization therapy (CRT) is a technique that uses a bi-ventricular pacemaker to synchronize the contraction of the bottom chambers of the heart, improving pumping action and reducing heart failure symptoms.
According to study results published in the New England Journal of Medicine (May, 2004: 350(21); 2140-2150) persons with advanced heart failure have a reduced risk of death and disability when cardiac resynchronization therapy (CRT) is used in conjunction with implantable defibrillator therapy. Researchers report in the Journal of American Cardiology (July, 2002: 40(1); 111-8) that the clinical benefits endure through one year follow-up.
Not all persons with heart failure meet the specific criteria for CRT, and it does not replace the need for heart failure medications.
Many who qualify for CRT also may benefit from having an internal cardioverter defibrillator (ICD), which monitors the heart rhythm continuously and delivers therapy in the form of fast pacing or shocks as needed. The ICD provides life-saving therapy that is delivered as soon as a problem is detected.
Persons with an ICD who did not meet the criteria for CRT when receiving the ICD may have the existing ICD upgraded, or reprogrammed, to provide CRT if the need arises. This type of upgrade may require additional lead placement.
Does the Heart & Vascular Center at UVa offer cardiac resynchronization therapy for eligible persons with heart failure?
Yes. UVa has electrophysiologists who are experts in the field of cardiac resynchronization therapy and implanting and calibrating devices, including internal cardioverter defibrillators. In addition, UVa has a Device Clinic where patients can receive care from five highly trained nurses who specialize in troubleshooting cardiac devices.
