I've just stumbled across this site whilst looking for info on self-monitoring INR. It's the International Self-Monitoring Association of Oral Anticoagulated Patients, but also has lots of information on valvular defects (animations of mitral and aortic regurgitation and stenosis), exercise after valve replacement, cardiac arrhythmia, dental prophylaxis, and much more. The links on the left of the page (particularly "Condition" and "Quality of Life") take you to these pages.
