Which is a complication of rheumatic heart disease? cardiac arrest valve vegetations and stenosis tachycardia transposition of the great vessels?

The correct answer is valve vegetations and stenosis.

Rheumatic heart disease (RHD) is damage to one or more heart valves that is caused by an episode/episodes of acute rheumatic fever. The normal blood flow through damaged valves is interrupted. The heart valves are unable to function properly, so the blood may flow backward through stretched valves (not closed properly), or may be blocked due to scarred valves (not opened properly). Heart surgery may be required for this condition.
