Improved doppler detection of proximal left anterior descending coronary artery stenosis after intravenous injection of a lung-crossing contrast agent: A transesophageal doppler echocardiographic study (original) (raw)

The study investigates the effectiveness of a lung-crossing contrast agent (SHU 508A) in enhancing the detection of proximal left anterior descending coronary artery stenosis using transesophageal Doppler echocardiography. By conducting this research on a cohort of 31 patients undergoing coronary angiography, it was found that the contrast agent significantly improved the visibility and Doppler signals of blood flow in the targeted artery, leading to higher sensitivity in identifying stenosis, thus providing a more reliable assessment tool for cardiac evaluation.
