Abstract

Primary cardiac neoplasms are uncommon with an overall incidence of 0.0017 to 0.02%. The majority of these tumors are benign and half of these tumors are myxomas. About 75% of them are located in the left atrium. Acute embolic cerebral stroke is major problem with increased mortality and morbidity. Embolus arising from cardiac origin costitutes about 20% of ischemic strokes. Atrial fibrillation is cause of more than 50% of cardiogenic emboli. Congenital heart diseases, such as atrial septal defect, patent foramen ovale, prosthetic and rheumatic heart valvular disease, dilated cardiomyopathy and endocarditis are predisposing factors for cardiogenic emboli. Emboli from primary tumors of the heart are extremely rare, with an incidence of 0.02 %. Myxoma is a potential source of systemic embolization to the brain or peripheral arteries. Thus, cerebral stroke may be the first manifestation of the presence of left atrial myxoma.

ÖZET

Primer kardiyak tümörler yaygın olmayıp insidansı % 0.0017 ila 0.02’ dir(1). (Bu tümörlerin büyük bir bölümü benign karakterlidir ve bunların da yarısını miksomalar oluşturur. Miksomaların yaklaşık %75'i sol atriyuma lokalizedir. Akut embolik serebrovasküler olay mortalite ve morbidite artışı ile olan bir sağlık sorunudur. İskemik felçlerin yaklaşık %20 'si kardiyak kökenlidir. Atriyal fibrilasyon kardiyojenik embolilerin %50'sinden fazlasını oluşturur. Atriyal septal defekt, patent foramen ovale gibi konjenital kalp hastalıkları, prostetik ve romatizmal kapak hastalıkları, dilate kardiyomiyopati ve endokardit kardiyojenik embolilerde predispozan faktörlerdir. Kalpten kaynaklı primer tümörlere bağlı emboli %0,002 insidansla oldukça nadirdir. Miksomalar beyin ya da periferik arterler için potansiyel bir sistemik embolizasyon kaynağıdır.  Bu nedenle sol atriyal miksomalar ilk bulgu olarak serebrovasküler olay olarak karşımıza çıkabilir.
