Electrical pacing therapy for treating mitral regurgitation
First Claim
Patent Images
1. A method comprising:
- identifying a regurgitant mitral or tricuspid valve in a patient;
implanting a pacing device in the patient for delivering pacing therapy to the heart through one or more pacing electrodes;
monitoring regurgitant flow in the patient; and
, delivering pacing therapy in a manner which optimally reduces the regurgitant flow.

Abstract
A method and apparatus are disclosed for treating mitral or tricuspid regurgitation with electrical stimulation. By providing pacing stimulation to a selected region of the left ventricle, such as one in proximity to the mitral valve apparatus in a manner which pre-excites the region during early ventricular systole, a beneficial effect is obtained which can prevent or reduce the extent of mitral regurgitation.

11. An implantable cardiac stimulation device, comprising:
-
one or more electrodes arranged therein and adapted to be disposed near a cardiac chamber;
pulse generating circuitry coupled to the one or more electrodes and configured to deliver pacing pulses to a cardiac chamber;
sensing circuitry coupled to the one or more electrodes and configured to detect electrical activity from a cardiac chamber;
a controller coupled to the pulse generating and sensing circuitry and configured to control the delivery of pacing pulses; and
,wherein the controller is programmed to deliver pacing therapy in a manner which optimally reduces the regurgitant flow as determined by monitoring the regurgitant flow while the making adjustments to the pacing therapy delivered by the device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
