young patients with paroxysmale tachycardia and diastolic heart murmur.
In TTE we could see a giant space-occupying lesion.
In TEE I could demonstrate the typical finding of a myxoma in LA with partial prolaps in mitral valve with beginning obstruction (PG mean of cw in mitral position about 5-7 mmHg).
In cardiac catheter I could demonstrate an intense perfusion by an atypical ramus of RCX.
Cardiac surgery is necessary.
