Resumen:
Background. Masses and cysts in the heart are well-known entities, but their low prevalence and non-specific symptoms makes the diagnosis difficult. We aimed to characterize the features of these entities in our environment.Methods. We carried out a search of patients who underwent surgery for tumors and cysts in the heart between 2002 and 2022 in the registry of the Department of Cardiology and Cardiac Surgery of Clinica Universidad de Navarra (Pamplona, Spain). Sociodemographic, clinical, histological, and surgical variables were collected.Results. We identified 13 patients; mean age was 63.08 +/- 15.17 years, 76.92% were female and 92.31% had at least one cardiovascular risk factor, e.g., BMI >= 25 kg/m2 and high blood pressure (61.54% and 53.85%, respectively). The most com-mon type of cardiac tumors were myxomas (69.23%). Around half (46.15%) were incidental; the most frequent symptom was dyspnea (53.85%); 30.77% of the patients were asymptomatic. The most commonly used imaging technique for the diagnosis was transthoracic Doppler echocardiography (69.23%). The agreement between the mean diameters before and after surgery was very high (ICC = 0.807, 95% CI: 0.450-0.943).Conclusions. We describe the features of masses and cysts in the heart (77% female patients) and provide information scarcely available in the literature, e.g., the most frequent cardiovascular risk factors for this population. A case of cardiac leiomyosarcoma and a case of intimal sarcoma of the pulmonary trunk are described, two extremely rare tumors for which there are few described cases.
