“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Since then, many approaches have been described in the literature, such as left atriotomy, right atriotomy and biatrial approach. [11][12][13][14][15][16][17][18][19] In our series, the approaches used for left atrial myxomas are left atriotomy in 73.6% (n=145), right atriotomy in 13.7% (n=27), and biatrial approach in 12.7% patients (n=25). Based on our findings, we found that the left atriotomy approach was much more convenient, simple, rapid, and safe approach for the excision of the left atrial myxomas.…”

patients (99 males, 130 females; mean age 37.1 years; range 7 to 63 years) with a primary or recurrent intra-cardiac myxoma underwent surgical excision at our institute. The diagnosis was made by transthoracic and transesophageal echocardiography. The basic surgical principle of complete wide excision was applied, and either unicameral (right or left atrial approach) or bicameral (both atria opened) surgical approach was used. Myxomas originating from the valve or valve annulus required a special attention. Postoperative echocardiograms were obtained in all patients before discharge. All patients were followed at three and 18 months, and five years postoperatively. Results:The most common presenting symptoms were dyspnea and palpitation. There were 197 left atrial, 27 right atrial, two left ventricular, and one each of right ventricular, right ventricular outflow tract and multiple myxomas. There were three early death events; however no late mortality was seen. During follow-up, all patients were in the New York Heart Association Class I and echocardiography showed good ventricular functions with normal pulmonary artery pressure. Seven patients developed sporadic recurrence of myxoma. The valves were competent in the patients who underwent valve repair. Conclusion:Based on our experience, we recommend the left atriotomy approach for left atrial myxomas and the right atriotomy approach for dumbbell-shaped left atrial and right atrial myxomas. Biatrial approach should be used in large and unusually located left atrial myxomas, while individualized approaches should be performed for others. To prevent recurrence, the surgical excision must include a substantial portion of normal endocardium near the base of implantation. The early mortality is commonly seen due to coronary embolism, and the late survival of patients after myxoma excision is usually excellent.

“…Primary cardiac tumours are rare (0.02-0.19%) [2][3][4]; myxoma is the commonest benign tumour in adults (45-50%) [5]. Myxomas present between the ages of 30 -70 years, and occur more frequently in women [5,6].…”

Left Atrial Myxoma With Concurrent Saddle Pulmonary Embolism and Duke’s B Colorectal Adenocarcinoma

A 64-year-old male with previous Duke's B adenocarcinoma of the colon, successfully treated with surgery and chemotherapy presented several months later with dyspnoea and atrial fibrillation. Investigations showed that he had a left atrial myxoma and a concurrent saddle pulmonary embolus. Full anticoagulation with unfractioned heparin was administered followed by surgical resection of the myxoma. Links between pulmonary emboli and underlying carcinoma are well established. However, to our knowledge, this is only the second case in the English literature where a patient has had both an adenocarcinoma of the colon and a myxoma. There are no links between a pulmonary saddle embolism and left atrial myxoma or between a right sided myxoma and a pulmonary saddle embolus and where the embolism is not a fragment of the myxoma.

“…Conventionally, thrombus does not enhance with gadolinium; however, large chronic thrombi may occasionally have peripheral enhancement, making differentiation between mass and thrombus challenging. [8] Typically, tumours demonstrate at the least partial uptake of gadolinium unless very avascular. The most common tumors metastasising to the heart are breast, kidney, oesophagus, lymphoma, leukaemia and melanoma.…”
