يعتبر الورم المخاطي القلبي البدئي السليم الأكثر شيوعا في القلب حيث يشكل 30-40% من الأورام البدئية ، تقدر نسبة حدوثه بحدود 0.5 – 1 لكل مليون نسمة في السنة .
يمكن أن يتشكل الورم المخاطي القلبي داخل أي حجرة من حجرات القلب مع وجود ميل الى التشكل في الأذينات و خاصة الأذينة اليسرى .
يمكن حاليا مع تطور العناية بعد العمل الجراحي إجراء استئصال للورم المخاطي جراحيا مع نتائج ممتازة حتى بالمشاركة مع إجراءات قلبية أخرى كجراحة الدسامات أو المجازات الاكليلية .
يجب إجراء التداخل الجراحي فورا بعد إرساء التشخيص بغية تجنب الاختلاطات المحتملة مثل الانصمام المحيطي أو الاضطرابات الهيموديناميكية .
أظهرت الدراسات الحديثة و نتائج المتابعة للمريض بعد العمل الجراحي انخفاض نسبة الوفيات عند المرضى الذين لديهم ورم مخاطي قلبي و خضعوا للاستئصال الجراحي ، مع نتائج جيدة على المدى البعيد .
Myxoma comprises 30 -40 % of all benign cardiac tumors in adults. And it occur
about 0.5 – 1 for each million in a year .
Myxoma occur in any chamber of the heart . but have a special
predilection for the left atrium.
Surgical resection is the only effective therapeutic option for
patients with cardiac myxoma . It may be done with any other cardiac surgery ( valve
replacement or CABG ) .
surgery should not be delayed because death from obstruction to flow within the
heart orembolization may occur in as many as 8% of patients awaiting operation .
New studies show a good result for the patients who undergo the surgical resection
for the myxoma . and low percentage of mortality .
