Review the incidence, literature prevalence, and anatomical distribution of primary cardiac tumours, with a focus on intracardiac myxomas.
Retrospective review of published autopsy series and compiled case reports of primary cardiac tumours.
Analysis of historical autopsy series totaling 40,000 autopsies alongside case series compilations (including reports by Yater, Mahaim, and Pritchard).
Primary cardiac tumours occurred in approximately 0.03% of 40,000 autopsies, with myxomata or myxomatous polyps comprising nearly 50% of these cases.
Approximately 75% of cardiac myxomata originate in the left atrium, with nearly all remaining cases located in the right atrium and rare reports in the left ventricle or mitral valve.

Population

Patients with primary tumors of the heart, specifically cardiac myxomata

Cardiac myxomata are rare primary heart tumors that predominantly occur in the left atrium.

Rare primary cardiac tumors merit inclusion in left atrial mass differentials; leaves open contemporary prevalence estimates beyond autopsy series.

Aldridge et al. (1960) studied this question.
