Echocardiographic predictors of acute kidney injury in neonates with a patent ductus arteriosus.

Objective: To investigate acute kidney injury (AKI) in neonates with a patent ductus arteriosus (PDA) including incidence, risk factors, and possible correlations between PDA-related echocardiographic measurements and AKI incidence.

Study Design: We conducted a single-center retrospective cohort study of infants admitted to the neonatal intensive care unit with a diagnosis of a PDA between July 2015 and July 2017. Infants were evaluated for development of AKI based on the KDIGO criteria and a multivariable logistic regression analysis was performed.

Sinus of Valsalva aneurysm rupture in an infant.

We present the case of a 10-month-old female with a right coronary sinus of Valsalva aneurysm with rupture into the right atrial appendage who presented with a murmur. Surgical repair was performed shortly after diagnosis with pericardial patch closure from within the aorta and closure of the right atrial rupture site. To our knowledge, this is the youngest child with sinus of Valsalva aneurysm with rupture to be identified in the literature.

A preliminary comparison of two-dimensional speckle tracking echocardiography and pressure-volume loop analysis in patients with Fontan physiology: The role of ventricular morphology.

Objective: Speckle tracking echocardiography (STE) may be a useful modality for assessing ventricular performance in patients with single ventricle physiology. However, STE's ability to accurately assess ventricular performance in this population is unknown. The objective of this study was to perform a preliminary comparison of STE measures of myocardial deformation to reference standard measures of function derived from pressure-volume loop (PVL) analysis.

Complications in total knee arthroplasty with and without surgical drainage.

The standard practice in total joint arthroplasty has included the use of postsurgical drains to minimize perioperative wound complications, particularly infection. This practice is not without cost and potential morbidity. Our recent cemented and cementless total knee arthroplasties (TKAs) have been done without the use of postoperative surgical drains and without any appreciable increase in wound complications.

Cementless S-ROM femoral component: effect of stem length on stability after extended proximal femoral osteotomy.

The extended proximal femoral osteotomy is becoming increasingly popular in revision total hip replacement. Our study was done to determine the femoral stem length required for stable fixation of a cementless femoral component after an extended proximal femoral osteotomy. Three lengths of the S-ROM femoral stem were implanted in paired cadaver femora and tested under torsional and axial loads.
