case_images: In between the calcification areas, a few reactive small thin-walled blood vessels were found (Figure 1(a)). In the periphery of the valve, an agglomerate of thin walled, often dilated, blood vessels was observed (Figures 1(b) and 1(c)).
case_images: Preoperative transthoracic echocardiography. Apart from a slightly thickened aortic valve (arrow), no clear abnormalities indicative for a hemangioma could be observed.
