A 128-element ultrasound device offers superior resolution to diagnose complex cardiac conditions and valvular diseases, including congenital defects such as atrial septal defects and ventricular septal defects, acquired heart diseases such as left atrial enlargement, and complications such as pulmonary hypertension. In Doppler Mode, a 128-element ultrasound device enables blood flow and pressure gradient measurement across valves, essential for identifying aortic stenosis and mitral valve insufficiency. Moreover, it assists cardiologists in the dynamic assessment of Postural Orthostatic Tachycardia Syndrome (POTS), showing increased oscillatory patterns of cerebral blood flow during a patient’s head-up tilt.
