Although cardiac lesions have been known to the existence since the Middle Ages, a search on Google or PubMed for cardiac lesions yields very few results. There are few original articles, case series, or clinical trials available on these rare but significant lesions. Cardiac lesions are usually asymptomatic and are detected only incidentally. Symptoms, if present, are varied and depend on the location of the area involved. The overall prevalence of primary cardiac tumors is between 0.17% and 0.19%. Cardiac tumors may be primary (benign or malignant) or metastatic (malignant). Only 25% of primary cardiac tumors are malignant, whereas metastatic tumors to the heart are 30 times more common. The aim of this case series is to highlight the clinical picture, presenting signs and symptoms, and the line of diagnosis of five such primary cardiac lesions that otherwise could remain undiagnosed until a late stage.
