Adult Echocardiography Practice Exam

What is the most common benign primary cardiac tumor?

1. sarcoma

2. myxoma

3. papilloma

4. rhabdomyoma

The correct answer is: myxoma

Myxoma is recognized as the most common benign primary cardiac tumor found in adults. These tumors are typically located in the left atrium and can present with a variety of symptoms due to their potential to obstruct blood flow or cause systemic embolization. Myxomas are often described as pedunculated, meaning they are attached by a stalk, and they can exhibit variable sizes and morphologies, often having a gelatinous consistency. The predominance of myxomas is also linked to specific demographics, with a notable prevalence in females and a peak incidence during middle age. Additionally, the familial type of myxoma has been associated with genetic conditions such as Carney complex, contributing to its recognition in clinical practice. Understanding the characteristics and clinical implications of myxomas is essential for echocardiographic assessment, as these tumors can be detected through imaging and often require surgical intervention for resolution. Their benign nature contrasts with other types of cardiac tumors, which may carry different prognoses and treatment considerations.
