Giant Right Ventricular Outflow Tract Myxoma Mimics Pulmonary Embolism: A Case Report

Right ventricular myxoma is very rare, especially its originating from the right ventricular outflow tract (RVOT) and extending to the main pulmonary artery. Here, we report a case of a giant RVOT myxoma, indistinguishable from pulmonary embolism (PE). Although the myxoma is a candidate for urgent surgery, this case satisfied diagnostic criteria for PE and had no indication for intervention, according to the guideline. The strategy for this mass can be completely different, depending on the diagnosis. Surgical extraction was selected because of atypical clinical course, findings, and nagging debut for neoplasm. Then it made hemodynamic status stable by releasing RVOT obstruction and allowed to reveal the diagnosis as myxoma histopathologically.

Giant right ventricular myxoma presenting as right heart failure with systemic congestion: a rare case report

Background Myxoma is an uncommon disease and its symptoms vary greatly depending on size, location and mobility. Right-sided myxoma, especially right ventricular myxoma, is much rarer, and the symptoms are alien and uncharacteristic. The lack of understandings poses challenges to prompt diagnosis and timely treatment. Case presentation A 44-year-old female patient was diagnosed with giant right ventricular tumor. Right heart failure and systemic congestion caused by right ventricular outflow tract obstruction were observed on this case. Surgery was performed to excise the mass which was measured at 9.5 * 5.0 cm and confirmed as myxoma pathologically. Conclusions Right-side myxoma is easy to be unnoticed due to its low incident rate and atypical symptoms. Delay in surgical intervention might cause unrecoverable complications. More comprehensive understanding of the symptoms is expected to help improving the diagnose and treat of right-sided myxoma.

A Rare Case of Right Ventricular Myxoma with Tricuspid Valve Endocarditis

Background: Although myxoma is the most common form of benign cardiac tumor, which is a rare condition itself, less than 3-4% of cases are detected in the right ventricle (RV). The clinical presentations vary widely and are nonspecific, causing challenging diagnosis. Although rare, myxoma can coexist with infective endocarditis (IE). Case report: We report a rare case of right ventricular myxoma presenting with dyspnea and fever, which was later found to be complicated with concomitant tricuspid valve endocarditis during surgery as well as the performed surgical approach. Conclusion: RV myxoma is a rare entity requiring a high index of suspicion due to varying nonspecific presentations. Concomitant IE should be suspected in patients with persistent fever. Antibiotics and careful surgical approach are needed to prevent complications, including embolization.

Rare Association between Giant Right Ventricular Myxoma and Right Coronary Artery Tumour Blush with Complicating Pulmonary Tumour Embolism

Cardiac myxoma is a benign primary cardiac tumour which can present with nonspecific symptoms of right heart failure, syncope, exertional dyspnea, and pulmonary embolism. We describe a case of a right ventricular myxoma complicated with bilateral pulmonary embolism, with an incidental right coronary artery fistula but otherwise normal coronary anatomy on coronary angiogram. This case report emphasizes the importance of performing a transesophageal echo in the setting of pulmonary embolism to search for the origin of thrombus/tumour, and performing a comprehensive assessment is also necessary to rule out coronary artery disease, coronary artery fistula that may also represent a tumour blush.

Inverted Yoga and Near Syncope: An Unusual Diagnosis of Right Ventricular Myxoma

Primary cardiac tumors are extremely rare and are difficult to diagnose. Although usually benign in nature, myxomas require surgical resection due to their increased risk of embolic and cardiac complications, with the timing of resection dependent on the presentation and size of the tumor. However, if diagnosed early, patients with primary benign cardiac tumors have excellent prognosis following surgery. Therefore, a high index of suspicion and a wide differential diagnosis are very important in detecting rare conditions that can affect otherwise healthy individuals. We present an uncommon case of a right ventricular myxoma that was discovered when the patient was performing inverted yoga and experienced a near syncopal episode. Patient subsequently underwent an echocardiographic evaluation and was found to have a right ventricular myxoma that was excised. Although recurrence is rare, it is important for physicians to remain vigilant and continue careful and consistent follow-up for patients with a history of a cardiac myxoma.
