Akut ST elevasyonlu miyokard infarktüsü ve pulmoner ödem ile presente olan mitral kapakta atipik yerleşimli dev miksoma
Kardiyak miksomalar %0,0017-0,03 insidansına sahip oldukça nadir olan bir hastalık olup en sık üçüncü ve altıncı dekadlar arasında görülür. Olguların %65’ini kadınlar oluşturur. Olguların %75’inde sol atriyumdan, %18’inde sağ atriyumdan, %4’ünde ise ventriküllerden köken alırlar. En nadir görüldükleri yer ise kapak dokuları olup sıklık sırası triküspit kapak, mitral kapak, pulmoner kapak ve aortik kapaktır. Kapak kökenli miksomaları gerçek insidansı belirsizdir. Klinik belirtileri sistemik semptomlar, emboliler ve intrakardiyak obstrüksiyonlardan kaynaklanır. Güçsüzlük, ateş, kilo kaybı, eklem ağrıları sistemik semptomlardan bazılarıdır. Tromboemboliler tümoral dokunun kendisinden kaynaklanabildiği gibi kitle üzerinde organize olmuş pıhtılardan da meydana gelebilmektedir. Dispne, ortopne, baş dönmesi, senkop ve pulmoner ödem intrakardiyak obstrüksiyonlardan kaynaklanan semptomlardır ve lokalizasyon, boyut ve hareketliliğe göre değişkenlik gösterebilir. Bu makalede dispne, göğüs ağrısı ve taşikardi ile prezente olan ve ST elevasyonlu miyokard enfarktüsü, akut pulmoner ödem, pulmoner hipertansiyon, paroksismal atriyal fibrilasyona yol açan mitral anuler ve posterior kapakçıktan köken alan dev miksoma tanısı alan 77 yaşında bir kadın hastayı sunmayı amaçladık.

Atypically mitral valve originated giant myxoma presenting with acute ST-segment elevation myocardial infarction and acute pulmonary edema
Cardiac myxoma is a rare disease with an incidence of 0.0017-0.03%, and most frequently are seen between the third and sixth decades. The 65% of cases are female. They originate from left atrium in 75% of the cases, from right atrium in 18% and from ventricles in 4%. The most rarely seen cardiac origins are valvular tissues and respectively origin from tricuspid valve, mitral valve, pulmonary valve and aortic valve. The exact incidence of myxomas originating from the mitral valve is not clear. Clinical signs are classified in three groups such as systemic symptoms, symptoms related to thromboembolisms and symptoms related to intracardiac obstructions. Weakness, fever, weight loss, arthralgia are some of the systemic symptoms. Thromboembolisms are caused by either the tumoral tissue or the clot locating on the mass. Dyspnea, orthopnea, dizziness, syncope and pulmonary edema are examples of symptoms resulting from intracardiac obstructions, depending on the size, mobility and localization of the tumor. We aim to present a 77-year-old female presenting with dyspnea, angina pectoris and tachycardia and getting a diagnosis of a giant myxoma originating from the mitral annulus and posterior leaflet causing myocardial infarction with ST elevation, acute pulmonary edema, pulmonary hypertension, paroxysmal atrial fibrillation.
