Key result
Massive right atrial lipoma presents with atrial flutter, tachycardia-induced cardiomyopathy, and cardioembolism.
Why the study?
Intracavitary cardiac masses can cause serious complications including cardioembolism, arrhythmias, and heart failure, but their clinical impact requires further illustration.
Answers are grounded in this paper and cite their sources.
Intracavitary cardiac masses such as right atrial lipomas, while often incidental, can result in severe clinical consequences including arrhythmias and cardioembolism.
Intracavitary cardiac masses include thrombi, metastatic tumors, and primary benign or malignant tumors.1-3 These masses are often detected incidentally; however, they may also result in cardioembolism, inflow or outflow tract obstruction, valvular dysfunction, arrhythmias or conduction disturbances, heart failure, or sudden cardiac death.
