Right-to-left atrial shunting demonstrated by color Doppler echocardiography using the longitudinal right parasternal approach was reported in four patients with mitral stenosis following percutaneous transluminal commissurotomy (PTMC). All four patients experienced complications with severe tricuspid regurgitation before PTMC. Right-to-left atrial shunting on the color Doppler echocardiogram appeared during systole from the right atrium into the left atrium through the atrial septum coincided with the bulging of the atrial septum towards the left atrium due to impinged tricuspid regurgitant jet. This right-to-left atrial shunting disappeared in all patients from one to four months after PTMC.
