What are valvular disease causing CSD?

Low risk of CSD(if asymptomatic) after prosthetic aortic valve replacement, still there is a risk for CSD due to arrhythmias, prosthetic valve dysfunction or coexisting CAD. It is the second most common cause of death after valve replacement surgery (CSD) 2-4% after 7 years (20% of postop deaths) We don't know if mitral valve prolapse caused CSD, although its prevalence is high, but risk increases in case we have it with mitral regurg, LV dysfunction, myxomatous degeneration (risk to get infective endocarditis, cerebroembolus, SCD)
