OBJECTIVE Previous publications using nonconcurrent series of patients indicate improved survival for patients with hypoplastic left heart syndrome (HLHS) undergoing stage I palliation with a right ventricle to pulmonary artery conduit (NW-RVPA) vs. a modified Blalock-Taussig shunt (NW-BT). We compared postoperative outcomes in a concurrent series of(More)
BACKGROUND There are distinct physiologic differences between patients with single-ventricle lesions who have undergone the Norwood procedure with a right ventricle-to-pulmonary artery conduit (NW-RVPA) compared with those patients who have undergone the Norwood operation with a Blalock-Taussig shunt (NW-BTS). We evaluated bidirectional Glenn operation(More)
BACKGROUND Modification of the Norwood procedure has been reported to improve immediate postoperative mortality compared with the classic Norwood. Interstage mortality has not been shown to be improved with the modified Norwood probably because of the small number of patients from each institution. The goal of this study was to determine if meta-analysis(More)
OBJECTIVE Computer-aided auscultation in the differentiation of pathologic (AHA class I) from no or innocent murmurs (AHA class III) would be of great value to the general practitioner. This would allow objective screening for structural heart disease, standardized documentation of auscultation findings, and may avoid unnecessary referrals to pediatric(More)
BACKGROUND Electronic consultations (eConsult) allow for communication between primary care providers and specialists in an asynchronous manner. This study examined provider satisfaction, topics of interest, and efficiency of eConsult in pediatric hematology/oncology in Ottawa, Canada. METHODS We conducted a cross-sectional assessment of all eConsult(More)
BACKGROUND An electrocardiogram has been proposed to screen for prolonged QT interval that may predispose infants to sudden death in the first year of life. Understanding the reliability of QT interval measurement will inform the design of a screening program. METHODS Three pediatric cardiologists measured the QT/RR intervals on 60 infant(More)
BACKGROUND Hemorrhagic shock secondary to trauma is associated with poor survival. The impedance threshold device (ITD) has been shown to improve blood pressure and survival rates in an adult porcine model of hemorrhagic hypovolemia. Pediatric hemodynamics, anatomy, and physiology differ from adults. Evaluation of the ITD has not been previously assessed in(More)
OBJECTIVE To investigate the reporting of the analysis of interobserver and intra-observer variability within clinical research studies from five high-impact cardiology journals published in 2005. STUDY DESIGN AND SETTING A cross-sectional study using a combined electronic and manual search identified 180 of 511 eligible articles that reported the(More)
