A Silent Left Atrial Myxoma: A Rare Benign Cardiac Tumor

Cardiac myxomas are rare tumors. Esophageal adenocarcinomas are common tumors of the gastrointestinal tract. Simultaneous occurrence of these tumors has not been reported. A 52-year-old gentleman presented to our hospital with dysphagia and was diagnosed with esophageal adenocarcinoma. Routine echocardiography discovered a cardiac tumor in the left atrium. The cardiac tumor was surgically removed and biopsy confirmed a myxoma. We removed the cardiac tumor as the first step and then initiated neoadjuvant chemotherapy. It is ideal to constitute a multidisciplinary team to decide on the course of treatment in such cases.

Preoperative Examination

The patient was a 69-year-old male patient with cancer in the right lung and whose preoperative examination showed left atrial myxoma. Simultaneous surgery for both cardiac myxoma resection and a lobectomy by totally endoscopic surgery without robotic assistance was performed. First, the cardiac tumor on the heart was removed using a cardiopulmonary bypass (CPB), then a lobectomy without any new incisions was performed. This case provides evidence that in individual select patients, a left atrial myxoma resection and lobectomy can be performed under total endoscopy at the same time.

Long Term Follow Up

Abstract Infarction of the central nervous system secondary to embolism from left atrial myxoma is a recognized phenomenon. However, myxoma as the source of an embolus may be overlooked if an index of suspicion is not present during the evaluation of the patient with a stroke without a known cause. We present a case report that illustrates some of the pitfalls and characteristic findings present in the evaluation of these patients. The magnetic resonance image of multiple cerebral aneurysms and infarction associated with this condition is presented along with a unique, arteriographically proven resolution of a fusiform cerebral aneurysm after the removal of the cardiac tumor. A review of published case reports suggests that, if the cardiac tumor is recognized and treated quickly, the ultimate prognosis, while uncertain, is usually good. However, because the potential exists for recurrence of the cardiac tumor, for enlargement of the cerebral lesions, or for late development of cerebral lesions, long term follow-up is mandatory and a vigorous work-up must be pursued if the patient again becomes symptomatic or develops central nervous system manifestations for the first time.

Primary Cardiac Tumors

The most common benign cardiac tumor is cardiac myxoma,accounting for around 50% of all primary cardiac tumors. Cardiac myxoma is an uncommon cause ofcardioembolic stroke.Overall,cardioembolic stroke accounts for approximately 30% of all ischemic stroke of which 0.5% of cardioembolic strokes are attributable to a cardiac myxoma.It has an annual incidence of around 0.5 cases per one million people with female predominance. Early diagnosis is necessary to prevent its devastating complications such as embolic stroke and sudden cardiac death.We present a relatively rare case of an acute stroke as a first and only manifestation of an atrial myxoma

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.
