Dextrose contrast echocardiography reveals increased RV dimension and paradoxical septal motion in a case report.
Case Report (n=1)
Contrast echocardiography using peripheral dextrose injection demonstrated abnormal right ventricular dimensions, paradoxical septal motion, and right-to-left shunting in a patient with suspected cardiomyopathy.

May aid shunt detection in cardiomyopathy suspects via dextrose contrast echo; leaves open validation in larger cohorts.
A 61-year-old man with treated hypertension and a history of excessive alcohol intake was referred for echocardiography to rule out cardiomyopathy. He had a history of a heart murmur for 29 years and had the recent onset of shortness of breath on exertion. Results of the clinical evaluation were initially remarkable for an S4gallop and cardiac enlargement on chest x-ray film. A routine M-mode echocardiogram was abnormal, leading to the performance of a contrast echocardiogram by rapid-bolus hand injection of 10 mL of 5% dextrose into a peripheral vein. Figure 1 is an M-mode tracing after this injection. What is your diagnosis? Fig 1.—M-mode echocardiogram. Right ventricular (RV) dimension (45 mm) is increased and there is paradoxical motion of ventricular septum (VS) relative to posterior wall (PW). Contrast effect after peripheral vein injection of dextrose appears in RV (large arrowhead). Small number of contrast echoes in left ventricle

Jack W. McWatters (1982) conducted a case report in Suspected Cardiomyopathy (n=1). Contrast echocardiography was evaluated on Echocardiographic findings. Contrast echocardiography using 10 mL of 5% dextrose in a 61-year-old man revealed increased right ventricular dimension (45 mm) and paradoxical motion of the ventricular septum.
