Early Diagnosis of Cardiovascular Diseases in Workers: Role of Standard and Advanced Echocardiography

Figure 10

A 46-year-old male patient with valvar aortic stenosis (AS) and angina pectoris. Patient had aortic valve surgery. (a) Left ventricular hypertrophy from pressure afterload. (b) High transvalvular pressure gradient (81 mmHg peak, 44 mmHg mean) by color Doppler. (c) Reduced aortic valvar area (0.7 cm²) by TEE. (d) Aortic pressure gradient reduction (12 mmHg peak, 7 mmHg mean) after aortic valve surgery. Ao = aorta; IVS = interventricular septum; LA = left atrium; LV = left ventricle; PW = LV posterior wall; RA = right atrium.
