RV Diastolic Dysfunction Causing Cyanosis
A 73-year-old woman presented with profound central cyanosis and a history of minor stroke. She had normal heart morphology, normal pulmonary artery pressure, and normal coronary angiography. A massive right-to-left shunt was demonstrated at atri- al level, with normal pulmonary venous saturations and PO2 values. The reason for this huge right-to-left shunt is illustrated by the diastolic pressure curves, representing compliance di erences between the right and left ventricles (Figure 6). Other causes of atrial right-to-left shunt, including pulmonary dis- ease, pulmonary vascular disease, RV hypertrophy, RV
