Is There Any Other Way Apart From Surgery For Mitral Valve Prolapse?

Have mitral valve prolapse. Diagnosed over 30 years ago. No problems besides a slight gurgle sound from time to time. Had echo stress in 2002, said very mild. No problems until August 2013, palpitations, racing heart, more and more often. Doc recommended stress echo and it had gotten much worse. Stress test almost 11 minutes on treadmill. Told me I would need surgery, but risk/reward not there yet. Always had anxiety and obviously this has not helped. Hard to take deep breaths and have bad cough at times. Before I went to doc had the palpitations but was able to ignore and live normal. Now I feel like I am just waiting for the surgery. I know stress/depression is part of it. I read it is rare for most to ever get surgery. They also said it takes decades to get worse. Is there a chance I may never need surgery?
