Final answer:
The most common primary benign cardiac neoplasm is: C. Myxoma.
Step-by-step explanation:
The most common primary benign cardiac neoplasm is a C.myxoma. Myxomas are typically found in the atria of the heart, most commonly the left atrium. These tumors are composed of connective tissue and have a gelatinous or mucoid appearance.
Myxomas are notable for their potential to cause symptoms such as obstructing blood flow, leading to complications like embolism. Surgical removal is often the primary treatment for myxomas due to the risk of complications and the potential for obstruction or embolization.
While fibromas, lipomas, and papillomas can occur in the heart, myxomas are more prevalent, making them the most common primary benign cardiac neoplasm. Understanding the characteristics and prevalence of these cardiac tumors is crucial for healthcare professionals involved in the diagnosis and management of cardiac conditions.
