From: Transthoracic echocardiography monitoring during ASD closure using an artificial hand system

Fig. 1

a The AH-TTE monitoring system consists of an artificial hand (AH) and a supporting device. The transthoracic transducer is held by the AH and secured in place at the subcostal area by locking the control button to obtain subcostal views and provide real-time TTE imaging during the entire procedure. b A 4-year-old girl during ASD closure using AH-TTE monitoring system. The AH grasping the transducer was placed in the subcostal area (arrow 1: AH; arrow 2: supporting device) and the procedure was performed after the area was covered with an aseptic cloth. c The correspondent real-time TTE imagings (arrow 3 in B) were demonstrated during ASD closure procedure. C1: An ASD (11.5 mm in size) with a left-to-right shunt. C2: The waist length of the ASD was 11.3 mm (denoted by the two-way arrow) as determined by balloon sizing. C3: The correct passing of the catheter through the defect. C4: The left disc (LD) was deployed in the LA. C5: The LD was pulled back against the atrial septum. C6: The RD was opened in the RA. C7: The RD was deployed in the RA. C8: An 11-mm Amplatzer™ Septal Occluder was successfully implanted and positioned in the atrial septum without requiring shunting.
