If patch overrides the pulmonary valve annulus, pulmonary regurgitation is common.Physical examination may be deceptive after classic tetralogy repair, with severe pulmonary valve regurgitation difficult to detect.Echocardiography/Doppler may underestimate significant pulmonary valve regurgitation. Be wary if the RV is enlarged or enlarging.Arrhythmias are common; periodic ambulatory monitoring is recommended.Serious arrhythmias and sudden death may occur if the QRS is wide or the RV becomes quite large, or both.
