Abstract 15102: Benign Cardiac Neoplasms in the United States - A Thirteen-year Review

Abstract

Introduction: Benign cardiac neoplasms (BCN) are rare; with varying reported incidence and a paucity of epidemiologic studies. The purpose of our review was to add to the small body of literature describing the characteristics and trends of BCN in the US. Methods: This study is a retrospective review of data from the HCUP-NIS Database from 2002-2014. Inclusion criteria consisted of the presence of indication for BCN. Additionally, we queried the database for BCN-associated comorbidities. SAS studio was utilized for analysis. Results: The data consisted of 482,872,274 weighted discharges. There were 45,568 weighted discharges that had BCN. Sixty four percent were women. Median cost per admission was 51,799 USD, five times higher than the national average. A total of 1,267 (2.78%) patients died during the admission. Stroke and arterial embolization were reported in 6730 (14.76%) and 573 (1.26%) weighted discharges. Weight loss, fever and endocarditis were reported in 311 (0.68%), 383 (0.84%) and 869 (1.91%) patients, respectively. Pulmonary hypertension co-occurred in 3440 (7.55%) patients. Episodes of atrial tachyarrhythmias, ventricular arrhythmias, syncope and cardiac arrest were reported in 13,184 (28.93%), 1,471 (3.23%), 1,055 (2.32%) and 393 (0.86%) cases. Sinus node dysfunction, severe AV nodal block co-occurred in 1,005 (2.21%) and 930 (2.04%) patients. Conclusions: We identified a low incidence of BCN in the US over the 13-year study period. Since the prevalence for BCN is low, clinicians must maintain a high index of suspicion due to the high morbidity and mortality.
