Project description:A 40 year-old athletic woman presented with worsening dyspnea on exertion over the preceding several months. Chest radiograph showed borderline cardiomegaly and subsequent echocardiography demonstrated a 5.0-cm left atrial mass as well as left-to-right interatrial shunting through a patent foramen ovale. Cardiac magnetic resonance imaging was performed, which demonstrated signal characteristics consistent with an atrial myxoma. The patient then underwent urgent surgical treatment with good technical and clinical outcome. Histologic examination confirmed an atrial myxoma. Cardiac magnetic resonance imaging was valuable in characterizing the nature of the atrial mass and patent foramen ovale, helping guide the surgical approach.

Left atrial myxoma causing near‐total mitral valve obstruction

Project description:Abstract Cardiac myxomas are the most common primary cardiac tumors in adults, with the left atrium being the most frequently affected. Echocardiography is the diagnostic modality of choice. The most effective treatment for cardiac myxomas is surgical excision. We present a clinical video of a large left atrial myxoma causing mitral valve obstruction, highlighting the importance of echocardiography as a diagnostic modality to facilitate referral to a tertiary center.

Left Ventricular Myxoma Causing Posterior Circulation Stroke.

Project description:Myxoma is a cardiac tumor most commonly found in the left atrium, presenting most frequently with dyspnea, chest pain, and constitutional symptoms. Hereby, we are presenting a rare case of cardiac myxoma originating from the left ventricle, presenting with an ischemic stroke in a young individual. He underwent surgical excision of the mass.

Left atrial myxoma with biventricular dysfunction.

Project description:Occurrence of left atrial myxoma with severe ventricular dysfunction without any obstructive coronary artery disease, as presented in our case, is very rare. It may be due to undiagnosed concomitant dilated cardiomyopathy or unknown cardiodepressant effect of myxoma which warrants further research.

Case report: left atrial Myxoma causing elevated C-reactive protein, fatigue and fever, with literature review.

Project description:BACKGROUND:A cardiac myxoma in a young person may pose a diagnostic challenge as symptoms may be variable and the differential diagnosis is wide. The differential diagnosis can include rheumatic mitral valve disease, pulmonary hypertension, endocarditis, myocarditis and vasculitis. CASE PRESENTATION:This case report involves a 49?years old female with a 2.8?cm?×?3.4?cm myxoma in the left atrium causing mitral valve obstruction. She presented with fatigue, fever of unknown origin, transient ischemic attack and shortness of breath. Prompt surgery is often recommended due to the risk of embolic complications or complete obstruction. Due to her symptoms, patient underwent successful cardiothoracic surgery to excise the myxoma within 2?weeks of confirmation by cardiac echocardiography. CONCLUSION:This case also emphasizes the diagnostic challenge as symptoms may be variable, ranging from fatigue, fever and shortness of breath to transient ischemic attack and at worst, sudden cardiac death. In conclusion, if a cardiac mass is suspected, echocardiography should be performed early. Surgical resection is curative and recurrence rate is very rare in sporadic isolated myxomas, however, recurrence can be higher in genetic diseases associated with increased frequency of myxomas such as Carney complex. This subpopulation of patients may present further research opportunity to learn more about the perioperative management of patients with myxomas such as determining the optimal time to surgical intervention and decision to anticoagulate.
