Coronárias ao modo B do Ecocardiograma

........................................................................................... . . ................................................................................................................................................................................ High frequency (7.5 MHz) two-dimensional ultrasound in combination with modified acoustic windows allowed visualization of the distal left anterior descending artery in 61 (85%) of 72 patients studied. Visualization was confirmed in one patient who underwent simultaneous high frequency ultrasound recording and selective dye injection into the left coronary artery.In addition, calcific coronary atherosclerosis was identified in one patient. The saphenous vein bypass graft along with its distal site of anastomosis was clearly seen in 3 patients and coronary artery flow was detected in 24 (33%).......................................................................................................... .

Estudo pioneiro de 1990 com transdutor de 7,5 MHz setorial obteve belas imagens da descendente anterior ao transtorácico na maioria dos pacientes estudados. ........................................................................................................................................................................................................................................................................... Outro estudo (LINK) também foi feliz em medir as coronárias em sua porção proximal. ............................................................................................................................................................................................................................................................................................................

. Vejam, nesse outro estudo (LINK), como fica perto da DA e podemos usar alta frequência nos transdutores. ....................................................................................................................................................................................................................................................................................................
