Aim
To explore the feasibility and value of transthoracic echocardiography (TTE) postprocessing subtraction technique in the detection of a stent in the coronary artery.
Method
Transthoracic echocardiography was used to examine 46 coronary artery stents in 30 patients by two‐dimensional ultrasound postprocessing subtraction technique. The shape of each stent and its flow patency were observed....
Aim
To explore the value of cough maneuver (CM) in detecting right‐to‐left (RLS) during contrast transthoracic echocardiography (cTTE) and its mechanism.
Method
We enrolled 196 patients with a high level of clinical suspicion of RLS underwent cTTE for RLS detection. Valsalva maneuver (VM) (blowing into a face mask connected to a sphygmomanometer at 40 mm Hg for 10 seconds) and CM were performed...
