This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.

Our aim was to evaluate postoperative morbidity and mortality following initial intervention, comparing primary repair versus palliative shunt in the setting of ductal-dependent tetralogy of Fallot. When neonatal surgical intervention is required, controversy and cross-center variability exists with regard to surgical strategy. The multicenter Pedi...
Objectives:
Strain and strain rate imaging have been reported to detect cardiac dysfunction more accurately than conventional methods in adults with Marfan syndrome, but their utility has not been proven in younger patients. We sought to determine whether strain and strain rate imaging would allow early detection of cardiac dysfunction in children...
Diastolic pulmonary artery pressure (dPAP) is equal to right ventricular pressure at the time of pulmonary valve opening. We studied the accuracy of dPAP estimated from Doppler profile of tricuspid regurgitation (TR) jet in pediatric patients.
Echocardiograms were prospectively performed on consecutive pediatric heart transplant recipients undergoi...
The aim of this study was to determine morphologic correlates of early reintervention for recurrent coarctation in infants undergoing surgical repair in the current era.
Medical records of infants who underwent repair of coarctation were retrospectively reviewed. Z scores for aortic segments, relative aortic arch segmental dimensions (indexed to as...
Our objective was to examine long-term outcomes of intraoperative pulmonary artery stents and determine risk factors for reintervention
Short-term outcomes of intraoperative pulmonary artery stents have been reported previously. However, long-term results are unknown.
We conducted a retrospective review of patients who underwent intraoperative pulm...
Purpose: Despite improvements in surgical repair of coarctation of the aorta (COA) in infancy, there remains a risk for recurrence necessitating further intervention. We sought to identify pre-operative echocardiographic features predictive of early recurrent COA after surgical repair in infancy.
Methods: A retrospective review of medical records...

... Management strategies for symptomatic young infants with tetralogy of Fallot vary markedly between institutions. 15 At our institution, infants older than 3 months of age with favourable pulmonary artery and without major non-cardiac co-morbidities underwent a primary repair with very low mortality. Many centres internationally are transitioning from surgical shunts toward either early surgical repair or trans-catheter palliation for the younger age group. ...
... then, numerous studies have been conducted to verify the existence of intrinsic cardiac impairment in MFS. [11][12][13][14][15][16][17][18][19] These studies concentrated on observing differences in cardiac structure and function between Marfan patients and healthy individuals; however, results of these studies are inconsistent. Intrinsic cardiac impairment in MFS may have a significant impact on perioperative management and long-term outcomes in Marfan patients; therefore its role in MFS must be verified. ...
... In the absence of PR, PADP can be estimated from TR. [65][66][67][68] TR velocity at the time of PV opening is applied to the simplified Bernoulli equation to approximate PADP at this time, as RV pressure and PADP are equal at the time of PV opening. 69 mPAP, calculated as 1 / 3 (PASP) + 2 / 3 (PADP), can be determined by echocardiography in several ways, although none demonstrated superiority to the others in common clinical utility. ...
... Since its introduction in pediatric patients in the late 1980s [1,2], endovascular stent implantation has shown tremendous promise in providing safe and effective alternatives to surgical therapy for an everexpanding list of obstructive lesions [3][4][5][6][7][8]. However, substantial variability exists in anatomy and somatic and vessel size among pediatric patients with complex CHD. ...
