Abstract 16339: Clinical Utility of Mobile Echo for Structural Heart Disease Screening in Mobile Medical Outreach services
Introduction: Since 2008, we have employed mobile notebook-style echocardiographic machine for structural heart disease screening in abroad charity medical services. In 2015, we used palm-held ultrasonoscopic scanner. The diagnostic yields were analyzed.
Materials and Method: Between 2008 and 2014, we provided 7 extended annual charity medical services to rural Vietnam villages. A notebook style mobile ultrasound machine was employed for cardiologic evaluation. In 2015, a pocket sized ultrasonoscopic scanner was used. The latter is about 1/10-1/20 of the former in weight. The notebook style machine is capable of performing all kinds of M mode, 2D and Doppler echocardiography except 3D image. The pocket machine is for performing 2D gray scale and color image only.
Results: A total of 359 patients underwent cardiovascular examination by notebook style machine. For the pocket sized scanner, a total of 78 patients underwent examination. For the notebook style machine, organic structural heart diseases were found in 52 patients (6 had patent ductus arteriosus, 13 had ventricular septal defect, 2 had atrial septal defect, 3 had Eisenmenger complex, 3 had complex cyanotic heart disease, 2 had Tetralogy of Fallot, 2 had hypertrophic cardiomyopathy (HCM), 1 had dilated cardiomyopathy (DCM), 2 had aortic stenosis (AS), 2 had mitral stenosis (MS), 14 had rheumatic mitral regurgitation and 2 had aortic regurgitation). For the pocket size machine, we examined 78 patients including one had Kawasaki disease with mild coronary anomaly, 1 had DCM, 1 had MS, 2 had AS, 3 had hypertension with concentric left ventricular hypertrophy.
Discussion: Our 8 years experience has shown that both types of mobile echo machine served well for the purpose of rapid-convenient heart diseases screening. In our experience, the notebook style machine carries more echo functions. While the pocket style machine still allows user to identify most of the common heart diseases except for smaller defect or trivial jets of any origin. However, the pocket machine is truly mobile and suited for clinical use in underserved areas. Cardiac diagnosis can be conveniently made and appropriate recommendations can be thus provided for people who have poor access to regular cardiovascular medical services.
