Common Benign Tumor

A left atrial myxoma is the most common benign tumor of the heart, but it is still uncommon, with a reported prevalence of 0.03% in the general population. In developing countries, patients may present late with a stroke or with pulmonary artery hypertension and ventricular dysfunction. We may need to address the mitral and tricuspid valves in such cases. This video tutorial illustrates the technical aspects of myxoma excision along with modified De Vega tricuspid annuloplasty. The mitral valve was structurally normal and free from tumor; therefore, it was not touched in the first place but had to be repaired because there was severe regurgitation after the tumor was excised. The presence of left ventricular dysfunction can indicate a dilated mitral annulus and the need to repair the mitral valve.

Primary Cardiac Tumors

Atrial Myxoma is the most common primary cardiac tumors accounting for about 50% of benign primary cardiac tumors, with the majority located in the left atrium. This is a case of large left atrial (LA) myxoma presented with features of mitral stenosis associated with moderate left ventricular failure (LVF) and mild pulmonary artery hypertension (PAH) The patient improved markedly after tumor excision.Pulse Vol.10 January-December 2017 p.29-33

Left Atrial Myxoma

Synchronous myxoma of the heart and other malignancies are extremely rare. We report a case of a 64-year-old man who had a large left atrial myxoma that obstructed the mitral valve, as well as an unrelated, coexistent cutaneous squamous cell carcinoma in the sacral area. During the preoperative evaluation for non-cardiac surgery, the tumor was diagnosed coincidentally by echocardiographic examination. Echocardiography findings were consistent with a large left atrial myxoma originating from the posterior wall and prolapsing into the left ventricular cavity through the mitral valve, causing mitral stenosis. The mass was successfully completely excised. Histologic examination of the mass confirmed the diagnosis of cardiac myxoma. We report a casual echocardiographic finding of a left atrial myxoma that obstructed the mitral valve outflow tract, and an unrelated, synchronous cutaneous squamous cell carcinoma in the sacral area.

Abstract A 61-year-old gentleman, he had shortness of breath while few weeks and getting worse, was presented to our hospital. His oxygen saturation was 94 %(O2 5L) and no crackles or rales were heard. His electrocardiogram was sinus tachycardia, and chest X-ray showed cardiomegaly and BNP level was elevated (260.3pg/mL). Transthoracic echocardiography (TTE) revealed huge mass(57 × 39mm) occupying left atrium (LA), the mass was flexible in cardiac cycle and prolapsing from LA to left ventricle, it seems like cardiac myxoma. We suspected mitral stenosis (MS) caused by the mass (peak trans mitral flow velocity 3.1m/s), mitral regurgitation(MR) was not significant, and moderate tricuspid regurgitation with pulmonary hypertension (peak systolic pressure 61 mmHg). We performed transesophageal echocardiography(TEE) and CT angiography revealed the mass at fossa ovalis, we decided surgery of removing the mass considering the risk of mitral annulus obstruction and embolism. Intraoperative findings, after taken off the mass, TEE showed moderate to severe MR not detected preoperative TEE. Additionally, it revealed the mitral annulus enlargement(42 × 38mm by 2D TEE) and may gradually induced by prolapsing the mass. Finally, surgery for mitral valve was performed and postoperative TTE showed no MR. The mass was diagnosed cardiac myxoma by pathology. MS is relatively common in patients with prolapsing LA myxoma , and it improves after removing the mass. In this case, mitral valve was no degeneration but enlarged mitral annulus and significantly MR had revealed after removing the mass. Keep in mind that there is possibility to underestimate of MR associated with LA myxoma. To take care of mitral valve complex sufficiently in such case, and to detect these findings at preoperative echocardiography, then more useful assessment for surgery. Abstract P1245 Figure.

Abstract Background Myocarditis is an uncommon, potentially life-threatening disease that presents with a wide range of symptoms. In acute myocarditis, chest pain (CP) may mimic typical angina and also be associated with electrocardiographic changes, including an elevation of the ST-segment. A large percentage (20–56%) of myxomas are found incidentally. Case summary A 62-year-old female presenting with sudden onset CP and infero-lateral ST-elevation in the electrocardiogram. The diagnosis of ST-elevation myocardial infarction was presumed and administered tenecteplase. The patient was immediately transported to a percutaneous coronary intervention centre. She complained of intermittent diplopia during transport and referred constitutional symptoms for the past 2 weeks. Coronary angiography showed normal arteries. The echocardiogram revealed moderate to severe left ventricular systolic dysfunction due to large areas of akinesia sparing most of the basal segments, and a mobile mass inside the left atrium attached to the septum. The cardiac magnetic resonance (CMR) suggested the diagnosis of myocarditis with concomitant left atrial myxoma. The patient underwent resection of the myxoma. Neurological evaluation was performed due to mild vertigo while walking and diplopia in extreme eye movements. The head magnetic resonance imaging identified multiple infracentimetric lesions throughout the cerebral parenchyma compatible with an embolization process caused by fragments of the tumour. Discussion Myocarditis can have various presentations may mimic acute myocardial infarction and CMR is critical to establish the diagnosis. Myxoma with embolic complications requires emergent surgery. To the best of our knowledge, this is the first case reported in the applicable literature of a myxoma diagnosed during a myocarditis episode.

Cardiac myxomas may have different clinical presentations that may expose the patient to sudden death due to obstruction of the left ventricle inflow. The authors report a case of 34 years old male who was diagnosed with left atrial myxoma that presented as mitral valve obstruction with severe pulmonary hypertension. He underwent emergent sternotomy under cardiopulmonary bypass and the myxoma was successfully removed. The postoperative course was uneventful.
