@DrRajeshG1 Dilated RA, RV , negative contrast in IAS region suggest os ASD, saline contrast first go in coronary sinus so possibility of PLSVC , parasternal long axis view may so this clearly.
@nihar_nayak2 Rheumatic severe MS, dilated CS, possibility of bidirectional ASD shunt so lutembacher syndrome but Subcostal view would be more helpful for ASD
