A detailed preoperative congenital transthoracic echocardiogram reported, in addition to the partial AV canal defect, a thickened MV with moderate-severe regurgitation (Figure 1A, Supplementary Videos 1, 2). Furthermore, thickened TV leaflets with moderate regurgitation was seen, especially during the Intra-Op transesophageal echocardiography (Figure 1B).
Excised papillary fibroelastoma of a TV leaflet on light microscopic examination (A) 40x original magnification, and (B) 100x magnification (hematoxylin and eosin stain).
