Left atrial myxoma resection

Once left atrial myxoma is diagnosed, surgery should be performed as soon as possible. Precautions for left atrial myxoma resection: 1. Perform extracardiac exploration and establishment of extracorporeal circulation after thoracotomy, and avoid touching and squeezing the heart before aortic blockage. Be careful to avoid blind separation and violent pulling when removing the tumor. Its purpose is to prevent tumor fragmentation and shedding, and strive to completely remove the tumor. 2. Rinse the heart cavity repeatedly with a large amount of physiological saline to avoid residual tumor debris. 3. Carefully explore the four chambers of the heart to avoid remaining coexisting other myxomas. It is reported that 15% of right ventricular myxomas are associated with atrial myxomas. Individual authors have even suggested that the ascending aorta and pulmonary artery be opened for exploration before the aortic blocking forceps can be opened. 4. Determine whether the atrioventricular valve is normal. If the valve is involved, its function should be reconstructed by shaping after resection. 5. All concurrent operations, such as coronary artery bypass surgery and valve replacement, should be performed after tumor removal. 6. Blood drawn back from the heart should pass through a filtering device to prevent tumor microemboli.
