Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.
[1] [5] Most myxomata arise sporadically (90%), and only about 10% are thought to arise due to inheritance. [6] About 10% of myxomata are inherited, as in Carney syndrome. Such tumors are called familial myxomata. They tend to occur in more than one part of the heart at a time, and often cause symptoms at a younger age than other myxomata.

The anterior mitral valve moves anteriorly during systole in these patients leading to dynamic LVOTO, and the increased mass of the septum leads to a physical narrowing for blood to pass through. Thus, both of these contribute to the left ventricular outflow tract obstruction seen in some cases of this disease.
Other possible symptoms are mitral valve prolapse, a large aortic root diameter, and myopia. [2] The skeletal features found in MASS syndrome include curvature of the spine , chest wall deformities, and joint hypermobility. [2] MASS syndrome and Marfan syndrome are overlapping connective tissue disorders. Both can be caused by mutations in the ...
The mitral valve is typically 4 to 6 square centimetres (0.62 to 0.93 sq in) in area and sits in the left heart between the left atrium and the left ventricle. [5] It has two cusps: an anterior one, and a posterior one. [6] The opening of the mitral valve is surrounded by a fibrous ring known as the mitral annulus. The anterior cusp attaches to ...
The surgeons will repair the mitral valve and partially remove the supramitral ring. [5] This surgical method is preferred to a valve replacement procedure. Classifying cardiac lesions in infants is quite difficult, and accurate diagnosis is essential.
Mitral valve prolapse classification. Diagnosis of mitral valve prolapse is based on modern echocardiographic techniques which can pinpoint abnormal leaflet thickening and other related pathology. Echocardiography is the most useful method of diagnosing a prolapsed mitral valve. Two- and three-dimensional echocardiography is particularly ...
