“…Regardless of technique, it is important to achieve complete resection of the tumor with a margin of safety to minimize chance of recurrence (13). With complete resection of the tumor, the risk of recurrence is approximately 3% (14, 15). Regular and long-term follow-up with clinical examinations and serial echocardiography is highly recommended (16), though a consensus on total duration of follow-up time has not been established.…”

Myxomas are benign, primary tumors of the heart. Atrial myxomas can present with a variety of clinical features including dyspnea, orthopnea, pulmonary edema, and pulmonary or systemic emboli. Constitutional symptoms such as fever and weight loss may also be present. We report the case of a young female presenting with headache, facial numbness, and vertigo, who was found to have a posterolateral medullary stroke secondary to a large left atrial cardiac myxoma.

Objectives:Although echocardiography has traditionally been used to diagnose myxoma, invasive or non-invasive coronary angiography can be useful diagnostic tool before surgery.Methods:We present a case of an angiographically detected left atrial myxoma feeding from the left circumflex coronary artery.Results:The patient underwent open-heart surgery to remove the left atrial myxoma. After ligation of feeding artery, the mass was successfully excisedConclusion:Preoperative coronary angiography can offer additional valuable information moreover detecting coronary artery disease. Because, there is sudden death risk from embolization during invasive coronary angiography, preoperative cardiac computed tomography angiography should be considered to plan the surgery of myxoma.

How does knowledge of the blood supply to an intracardiac tumour help?

Myxoma is a common benign tumour found in the heart. On reviewing literature, we found some left atrial myxomas receive blood supply from the right coronary artery. Performing a coronary angiogram in a cardiac tumour has the following uses: (1) it shows the vascularity that can be ligated by the surgeon at operation; (2) if there is a blood supply visible, it may not be an intracardiac thrombus; (3) the coronary angiogram may detect a myxoma even before an echocardiogram does so; (4) some myxomas may bleed into the right atrium or left atrium and this may be seen on coronary angiography. We show here the neovascularity of a left atrial myxoma and its blood supply from the right coronary artery. We recommend that all routine coronary angiograms be reviewed carefully for any signs of tumour vascularity or tumour blush as this would prevent missing early myxomas. Echocardiography is the gold standard for detection of myxomas but literature has a number of intracardiac tumours that were detected only by the tumour blush. Some left atrial tumours have been treated by occluding their blood supply.The absence of a blood supply on coronary angiography could rule out a benign cardiac tumour that usually has a blood supply.
