ABSTRACT

Background: The heart myxomas represent about 50% of the benign heart tumors presenting themselves in any age. With an unknown etiology, it is believed that there is a proliferation of certain mesenchymal totipotential cells with excessive production of glycosaminoglycans. Histologically, they are tumors but due to their strategic location may be fatal occasionally. Their habitual location is the foramen ovale, though they may settle in any heart chamber, mostly the left chamber. The clinical manifestations depend of the location, chamber involved, shape and size of the tumor, as well as the pedicle's longitude. They may embolize to the central nervous system and vascular tree. The diagnosis is done through a echosonogram and the treatment consist of the tumor extraction.
Material: A descriptive, retrospective study with the objective of showing the experience on myxomas in our hospital during six years.
Results: The most affected group was the 50-59 years old (37.5%), with a prevalence female gender (62.5%). The main form of clinical presentation was a combination between obstructive and neurological (62.5%) with the following symptomatology: dyspnea (70%) vertigo (62.5%), syncope (37.5%), parasthesia (25%), cardiac murmur, cephalgia and precordial pain (12.5%).
Conclusion: The technique of right atrium approach with septostomy and closure with autologous pericardial graft, including the optical post-surgery handling showed a fewer number of complications and better prognosis.
