AIM/METHOD: The @entity1002 ( @entity1002 ) is a rare @entity299 with clinical findings of severe @entity337 . We report the echocardiographic differentiation of different anatomical variants of @entity1002 in two @entity1 . RESULTS: Echocardiography in both @entity1 demonstrated severe enlargement of the ascending aorta and the left ventricle. In the first @entity1 the @entity1002 originated from the ascending aorta above the right coronary sinus and entered the left ventricle just below the aortic valve. In the second @entity1 the @entity1002 originated above the left coronary sinus and took a lateral course to the left ventricle. Colour-Doppler-sonography in both @entity1 confirmed a systolic-diastolic flow across the tunnel. Many @entity1 have associated @entity299 . Exact determination of the morphology of the aortic valve and coronary arteries is mandatory for surgical repair. Postoperative follow-up studies focus on the function of the aortic valve and the left ventricle. CONCLUSION: Differentiation of different anatomical variants of @entity1002 is possible trough echocardiography. Cardiac catheterization is required only in cases with inadequate information about coronary artery anatomy.
