Pediatric resident auscultation skills were poor and did not improve after an outpatient cardiology rotation. Auscultation skills did improve after the use of a self-directed cardiac auscultation teaching program. These data have relevance given the American College of Graduate Medical Education's emphasis on measuring educational outcomes and documenting clinical competencies during residency training.

Isomerism of the right atrial appendages is associated with anomalies of pulmonary venous return, which may be obstructive. The associated pulmonary arterial obstruction, however, has been reported to "mask" the pulmonary venous obstruction, with resultant pulmonary edema following augmentation of the flow of blood to the lungs. We postulated that the frequency of "masked" pulmonary venous obstruction has been over-reported in the literature. To ascertain the true situation, we evaluated the frequency of "masked" pulmonary venous obstruction in a large, unselected, group of patients with isomerism of the right atrial appendages. We evaluated the clinical, anatomic, and radiographic data of 65 newborns seen with this syndrome since 1970. Development of pulmonary venous obstruction, both before and after systemic-to-pulmonary shunting and/or infusion of prostaglandin E1, was determined and correlated to clinical and radiographic findings. Of the 65 patients, 19 (29%) were ultimately diagnosed with pulmonary venous obstruction. The pulmonary veins themselves connected in infradiaphragmatic fashion in 10 patients, supracardiac in 3, to the atriums directly in 1, and in mixed fashion in the other 5. Pulmonary venous obstruction was readily apparent in 15 of the 19, as demonstrated by pulmonary edema on initial chest radiography. The remaining four cases ultimately diagnosed with pulmonary venous obstruction received augmentation of pulmonary blood flow with resultant pulmonary edema. Of these four severely cyanosed patients, pulmonary vascular markings on the initial chest radiograph had been normal in one but increased in three. Due to the presence of these clinical markers, they do not truly represent "masked" pulmonary venous obstruction. Except for two patients with minimally obstructed pulmonary arterial blood flow, 44 patients without pulmonary venous obstruction had normal or decreased pulmonary vascular markings at presentation. Of these 44, 14 received infusions of prostaglandin E1, with none developing pulmonary edema. We conclude that pulmonary venous obstruction is usually readily apparent at time of presentation in patients with right isomerism, and that "masked" pulmonary venous is a very rare event which has been over-emphasized in the literature. Careful evaluation of clinical and radiographic findings at time of presentation can correctly identify pulmonary venous obstruction in such patients.

A dvancements in technology and broadband have revolutionized the current practice of medicine. The field of pediatric cardiology is no exception given the need for prompt diagnosis and reliance on cardiac imaging to identify infants and children with potentially life-threatening cardiovascular disease. As the relationship between telemedicine and pediatric cardiology has advanced, it has created a need to develop a broad, comprehensive document reviewing all the various aspects of telemedicine in pediatric cardiology. For more than a decade, a significant body of literature has been published describing individual experiences and practices, yet there remains no comprehensive statement or document summarizing this rapidly advancing field. In an effort to describe the collective experience and to provide structure and guidance for pediatric cardiology practitioners and healthcare providers, we have developed a scientific statement on the use of telemedicine in pediatric cardiology.Specific areas explored in this document include both neonatal and fetal teleechocardiography, implications for training community sonographers, pulse oximetry programs, qualitative improvement and appropriate use criteria initiatives, and remote electrophysiological monitoring. This document also includes teleconsultation and teleausculation, direct-to-consumer and home monitoring programs, and a look into the use of telemedicine and pediatric cardiology in the intensive care setting. Furthermore, a detailed review of the legislative, public policy, and legal aspects of telemedicine is provided, along with financial and reimbursement information.Several terms are used in the literature interchangeably; a brief explanation is provided to help readers of this document. The term telehealth is defined as the use of technology to bridge distances in any aspect of medicine; telemedicine is the specific application of technology to conduct clinical medicine at a distance. The term telecardiology is defined as the broad application of telemedicine in the field of cardiology specifically, and tele-echocardiography is the most common application used within this field. ECHOCARDIOGRAPHY AND TELEMEDICINEEchocardiography is the most commonly used noninvasive cardiovascular imaging modality and is considered to be both safe and cost-effective. Tele-echocardiography can be described as a process in which a provider or a technician obtains cardiovascular ultrasound images from a given patient and these images are subsequently transmitted to an offsite location where a cardiologist can provide further analysis and interpretation. Thus, tele-echocardiography enables expert interpretation and consultation in a rapid and potentially geographically disparate fashion, enabling prompt and accurate decision making involving triage, transport, and therapeutic priorities. Tele-echocardiography is now routinely used across the age and subspecialty spectrum in pediatric cardiology.
