Summary of "Review of current challenges in the diagnosis and therapy of cardiac myxomas."

Cardiac myxoma is the most common benign cardiac tumor. Cardiac myxoma location in general population is approximately 75% in the left atrium and typically arising from the foramen ovale, 23% in the right atrium and only 2% in the ventricles. The symptoms of cardiac myxomas depend on the size, mobility and relation to surrounding cardiac structures. Neurological complications resulting from cardiac myxomas are seen in 20-25% of patients. Molecular genetic studies show that mutations in PRKAR1A gene cause inherited myxomas in setting of the Carney complex tumor syndrome. Cardiac myxoma resection is a low complications rate cardiac surgery operation and the 30-mortality rate is accounting about 0-10%. Recurrence rate of CM is 5 % approximately and may be observe months or years after operation. Long-term follow-up is needed in all patients after tumor resection with transthoracic echocardiography.

Medical and Biotech [MESH] Definitions

Autosomal dominant syndrome characterized by cardiac and cutaneous MYXOMAS; LENTIGINOSIS (spotty pigmentation of the skin), and endocrinopathy and its associated endocrine tumors. The cardiac myxomas may lead to SUDDEN CARDIAC DEATH and other complications in Carney complex patients. The gene coding for the PRKAR1A protein is one of the causative genetic loci (type 1). A second locus is at chromosome 2p16 (type 2).

Published materials which provide an examination of recent or current literature. Review articles can cover a wide range of subject matter at various levels of completeness and comprehensiveness based on analyses of literature that may include research findings. The review may reflect the state of the art. It also includes reviews as a literary form.

An article or book published after examination of published material on a subject. It may be comprehensive to various degrees and the time range of material scrutinized may be broad or narrow, but the reviews most often desired are reviews of the current literature. The textual material examined may be equally broad and can encompass, in medicine specifically, clinical material as well as experimental research or case reports. State-of-the-art reviews tend to address more current matters. A review of the literature must be differentiated from HISTORICAL ARTICLE on the same subject, but a review of historical literature is also within the scope of this publication type.
