Ultrasound/cardiac echocardiography

Perflutren is an ultrasound agent that consists of per-fluoropropane gas encapsulated in hpid microbubbles. It has been used in patients with suspected cardiac disease and suboptimal basehne echocardiography in doses of 5 pl/kg (n — 85) or 10 pl/kg (n — 84) 42 patients received isotonic saline (14). The magnitude of chnically useful opacification was not dose-dependent, but its duration... 

Prenatal monitoring suggested maternal serum a-fetoprotein screening for neural tube defects before the twentieth week of gestation and high-resolution ultrasound at 16-1 8 weeks gestation to detect cardiac abnormalities fetal echocardiography is recommended if lithium is... 

Intracardiac echocardiography is emerging as an ideal real-time modality to guide intracardiac interventional procedures. ICE allows accurate appreciation of cardiac anatomy and detailed visualization of specific anatomic structures, the most important factors in planning and guiding catheter-based interventional techniques [15-17]. In our daily practice, ICE is performed using a commercially available 9-F/9 MHz ultra-ICE catheter-based ultrasound transducer (EP Technologies, Boston Scientific, San Jose, CA, USA). The Ultra ICE catheter is introduced percutaneously into the...
