Comparative StudyValidation of cardiac output using real-time measurement of oxygen consumption during cardiac catheterization in children under 3 years of age.
To validate a method for determination of cardiac index (CI) using real-time measurement of oxygen consumption (VO2 ) in young children undergoing cardiac catheterization. ⋯ In children <3 years with a structurally normal heart, RT-VO2 generates highly accurate determinations of Fick CI as compared with TDCI. Additionally, in this population, VO2 derived from the LaFarge and Lundell equations generates accurate Fick CI compared with TDCI. Future studies are needed to identify factors associated with inaccurate VO2 generated from these predictive equations.

Comparative StudyRight ventricular volumes assessed by echocardiographic three-dimensional knowledge-based reconstruction compared with magnetic resonance imaging in a clinical setting.
A technique that uses two-dimensional images to create a knowledge-based, three-dimensional model was tested and compared to magnetic resonance imaging. ⋯ The knowledge-based three-dimensional right ventricular volume method was highly feasible. Intra and interobserver variabilities were satisfactory. Agreement with magnetic resonance imaging measurements for volumes was reasonable but unsatisfactory for ejection fraction. Knowledge-based reconstruction may replace magnetic resonance imaging measurements for serial follow-up, whereas magnetic resonance imaging should be used for surgical decision making.

Case ReportsCoronary sinus obstruction after atrioventricular canal defect repair.
The coronary sinus can become obstructed with any instrumentation at or near the ostium such as in atrioventricular canal defect repairs. This complication may lead to a wide range of consequences including dyspnea, angina, myocardial infarction, and sudden death. The following report illustrates the importance of careful perioperative echocardiographic evaluation of the coronary sinus in procedures that may affect the sinus and its ostium.

The significance of transesophageal echocardiography in assessing congenital heart disease: our experience.
The rapid expansion of pediatric cardiovascular surgery, along with the increase in the number of centers and operations, has also increased the use of intraoperative transesophageal echocardiography (TEE). Preoperative TEE allows for the confirmation of diagnoses established by transthoracic echocardiography and angiography, and also identifies possible additional pathologic conditions. TEE is also used to follow up on surgical repairs, determine the need for reintervention, and evaluate myocardial performance and the need for inotropic treatment. Our intention is to share the TEE findings before and after intervention for congenital heart disease in patients who received operations at our center, and the conclusions reached. ⋯ The use of intraoperative TEE in surgical centers for congenital heart disease allows for a significant reduction in mortality and morbidity. Intraoperative TEE performed by experienced pediatric cardiologists is therefore an absolute necessity.
