Summary
Primary cardiac myxomas are rare tumors, with most originating in the left atrium. This study highlights three cases of right-sided myxomas diagnosed via echocardiography.
Area of Science:
- Cardiology
- Oncology
- Pathology
Background:
- Primary cardiac tumors are exceptionally rare, occurring in 0.0017% to 0.19% of autopsies.
- Cardiac myxomas constitute approximately 50% of all primary heart tumors.
- Left atrial origin is most common (75-85%), followed by the right atrium (15-20%).
Observation:
- This report details three cases of right-sided cardiac myxomas.
- Echocardiography was the primary diagnostic tool for these right-sided tumors.
- Ventricular myxomas are exceedingly rare, accounting for only about 5% of cases.
Findings:
- The study confirms the rarity of right-sided cardiac myxomas.
- Echocardiographic diagnosis of right-sided myxomas is feasible.
- Literature review supports the infrequent occurrence of myxomas in the ventricles.
Implications:
- Increased awareness of right-sided myxoma presentation is warranted.
- Echocardiography plays a crucial role in diagnosing cardiac myxomas.
- Further research into the etiology and presentation of atypical myxomas may be beneficial.
