Massive right atrial myxoma presenting as syncope and exertional dyspnea: case report
نویسندگان
چکیده
Primary heart neoplasms are rare occurring with an estimated incidence of 0.0017-0.19%. Myxoma is the most prevalent primary heart tumor. The right atrium is an unusual localization, occurring only in 15-20% of myxoma cases. We report a rare case of a massive right atrial myxoma causing tricuspid valve obstruction and presenting as syncope and exertional dyspnea. This case illustrates the influence of myxoma's size, position and mobility as well as patient's body posture and respiration to the development of signs and symptoms. Three-dimensional echocardiography proved useful in surgery planning, allowing a better definition of the tumor outline and attachment.

Cardiac myxomas are rare. The clinical diagnosis of an atrial myxoma may occur in an asymptomatic patient but may also present with cardiac failure, syncope, arrythmias, or with vascular evidence of tumour embolisation. The delay in diagnosis from presentation is approximately ten months. We present the case of a 53-year-old woman who attended our Emergency Department with dyspnoea, fatigue and...

Intracardiac myxoma is the most frequent benign tumour of the heart. Although most (75%) are located in the left atrium (LA), myxomas are also found in the right atrium (18%), right ventricle (4%), and left ventricle (3%).They occur in all age groups, most frequently between third and sixth decade, while it is rare in the ninth decade [1,2]. Left atrial myxoma(LAM) is histologically benign and ...
متن کاملListening to syncope
A 35-year-old man presented with progressive exertional dyspnea (3 months) and syncopal attacks (1 week). He had tachypnea, tachycardia and hypotension. Examination revealed a mid-diastolic plop at the apex. Clinical suspicion was a left atrial mass with a ball valve-like mechanism (LA thrombus or LA tumors). Echo and cardiac MRIs with gadolinium enhancement (to differentiate between a tumor an...
متن کاملRight atrial myxoma and pulmonary embolism. Rational basis for investigation and treatment.
SUMMARY We report a case in which pulmonary embolectomy was crucial in the successful outcome of an operation to remove a right sided atrial myxoma. The association between such myxomata and embolisation is emphasised and guidelines for the rational investigation and treatment of such lesions are given. The occurrence of peripheral emboli is relatively common and well documented with left atria...
