I studied a case of Wolff-Parkinson-White syndrome associated with isolated tricuspid valve prolapse. During a health examination, a 61-year-old woman had been diagnosed as having Wolff-Parkinson-White syndrome. A 12-lead electrocardiogram and body surface maps suggested that preexcitation was on the right side of the interventricular septum. Echocardiography detected isolated tricuspid valve prolapse and a peculiar abnormal motion of the interventricular septum immediately after delta wave.
This case suggests that there may be some relation between tricuspid valve prolapse and abnormal motion of the interventricular septum in septal-type Wolff-Parkinson-White syndrome.
