In this episode, we review cardiac masses, including primary benign, primary malignant, and secondary (metastatic) cardiac tumors. Are malignant tumors much more likely to occur in the ventricles or the atria? If you see a myxoma in any cardiac chamber other than the left atrium, what syndromic complex should you suspect? What echocardiographic features distinguish benign and malignant cardiac masses? Which type of sarcoma is the most common primary cardiac tumor? What are the most common sources of metastatic cancer to the heart? Which cardiac chamber or junction would you find the moderator band, eustachian valve, crista terminalis, and Chiari network, which may be mistaken as cardiac masses? In what situation is resection of a papillary fibroelastoma indicated? How can you differentiate between Lambl's excrescences, fenestrated aortic valve, and nonbacterial thrombotic endocarditis? Tune in for answers to these questions. Difficulty Level: Intermediate You are listening to Hu Said: Cardiology Board Review Series (2024-2025 Season) Please subscribe, rate, and support the channel!
