Abstract:
Platypnoea-orthodeoxia is an infrequent syndrome that is usually associated with positional intracardiac right-to-left shunting. The authors report the case of a patient who presented with deteriorating severe dyspnoea and deoxygenation in the upright position that was partially relieved by recumbent repositioning. Dynamic echocardiography provided insight into the underlying anatomical and pathophysiological mechanisms as well as guidance for definitive therapy.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
