Current concepts in heart valve surgery.
After a period of relatively regimented approaches for mitral and aortic valve surgery, recent years have seen numerous innovations including improved prostheses, improved techniques for repair, better understanding of the physiology of ventricular function and myocardial protection, advances in anticoagulation control, and most recently the application of minimally invasive techniques. Each of these has contributed to the improved short and long term results obtained from valve surgery, and further evolution of these techniques will undoubtedly improve the results even more. As operative risks are decreased and long term results are improved, it is hoped that patients with valvular heart disease will be referred at progressively earlier stages of their disease for consideration for surgery. Earlier referral increases the likelihood that valve repair will be possible in the case of the mitral valve and also increases the odds that the outcome from valve surgery will be successful for both aortic and mitral valves.
