Valve surgery for regurgitant lesions of the aortic or mitral valves in advanced left ventricular dysfunction

Part of the Developments in Cardiovascular Medicine book series (DICM, volume 225)


Cardiologists and cardiac surgeons frequently must decide when it is appropriate to offer early surgical intervention to prevent compromise of left ventricular function from regurgitant lesions of the aortic or mitral valve. Both aortic and mitral regurgitation place a volume load on the left ventricle leading to dilatation and eventually impairment of left ventricular systolic function. This chapter however deals with the opposite issue: that of late surgical intervention after deterioration of left ventricular systolic function has occurred and reached advanced levels. Important questions to consider include (1) whether surgical intervention is contraindicated once advanced left ventricular dysfunction has become established (2) whether the risks of surgery are too high in this setting and (3) whether, even after successful surgery, improvements in left ventricular function, symptoms, or survival can realistically be anticipated.
