Background: Atrial myxomas are rare benign tumors; causing obstructive or embolic complications, and even death, depending on their site and size. Therefore, once diagnosed, it should be surgically resected emergency. Atrial myxomas are present about 75% in left atrium (LA) and about 15% in right atrium (RA). Early diagnosis is a challenge because of nonspecific manifestations, and sometimes is asymptomatic and discovered accidentally during TTE. Objective: Minimally invasive cardiac surgery (MICS) has benefits include cosmetically, less pain, shorter intensive care unit (ICU) and hospital stay. Methods: From Jan. 2011 to Sept. 2020, (20) patients (10 Sternotomy, 10 MI) underwent surgery for isolated resection of atrial myxoma. We reported outcomes; cardiopulmonary bypass time (CPB), cross-clamp time, conversion to median ST, length of stay, complications (stroke, renal failure, respiratory failure, reoperation, and infection),pain, patients satisfaction, recurrence and survival. Mean follow-up time was 6 month. Results: There is no significant difference in CPB or cross-clamp time between groups. No MI cases required conversion to a median ST. Length of stay is shorter in the MI group by 2.2 days (p = 0.045). There is no difference in morbidity or mortality between groups. Conclusions: A minimally invasive approach for atrial myxoma resection is safe, feasible, and favored over sternotomy.

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.
