Pediatrie Echocardiography: Applications and Limitations

Phoon, CKL; Divekar, A; Rutkowski, M
Echocardiography is an extraordinarily useful imaging technique in fetuses, infants, children, and adolescents. Recent technologic innovations have expanded its versatility in the pediatrie population. However, limited societal resources, limitations inherent to ultrasound imaging, and numerous imaging options even within the field of pediatrie echocardiography necessitate the discriminate and thoughtful use of echocardiography in children. The clinical assessment remains a critical prelude to echocardiographic examination of the pediatrie cardiovascular system

Transesophageal imaging of the mid to distal left pulmonary artery in congenital heart disease

Phoon CK; Rutkowski M
We assessed how well transesophageal echocardiography (TEE) images the left pulmonary artery (LPA) in congenital heart disease (CHD). Seventy-nine consecutive patients with CHD were studied. Ideal imaging displayed the mid to distal LPA from the takeoff of the upper lobe artery through the second bifurcation. Imaging quality was graded from 1 (excellent) to 5 (not visualized). Imaging quality was excellent in 8 (10%) patients, good in 25 (32%), fair in 23 (29%), and poor in 12 (15%); the LPA was not visualized in 11 (14%) patients. Imaging grade averaged 2.9 +/- 1.2 (SD) and correlated poorly with weight (r = 0.24) but was better in patients without prior operation (grade 2.8 vs 3.3, P <.05). In 2 patients, TEE showed residual stenosis. Thus informative LPA imaging by TEE can be achieved in many patients with CHD and has the potential to change intraoperative or postoperative treatment

Mathematic validation of a shorthand rule for calculating QTc

Phoon CK
The shorthand rule that the QTc will be normal if the QT interval is <1/2 the RR interval was mathematically validated. The rule was found to be applicable and useful, provided the heart rate is more than approximately 70 beats/min
