Abstract:
Papillary fibroelastoma(PFE) is a rare and benign primary cardiac neoplasm. The incidence of PFE in the left ventricle is lower than that in other parts of the heart. A 67-year-old female was referred to our cardiology department for treatment of severe cardiac failure due to mitral regurgitation. Transthoracic and transesophageal echocardiography coincidently revealed a 1.0 cm highly mobile mass attached by a stalk to the outflow tract wall of the left ventricle. The mass was easily detected using endoscope and successfully removed without any postoperative complications and was pathologically diagnosed as a PFE. In this report, we discuss the echocardiographic character of PFE and the usefulness of endoscope for the identification and resection of a PFE in the left ventricle.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
