The purpose was to create a time sequential three-dimensional virtual reality model, also referred to as a four-dimensional model, to explore its possible benefit and clinical applications. We hypothesized that this novel solution allows for the visuospatial benefits of the 3D model and the dynamic benefits of other existing imaging modalities.

Surgeons typically rely on their past training and experiences as well as visual aids from medical imaging techniques such as magnetic resonance imaging (MRI) or computed tomography (CT) for the planning of surgical processes. Often, due to the anatomical complexity of the surgery site, two dimensional or virtual images are not sufficient to successfully convey the structural details. For such scenarios, a 3D printed model of the patient's anatomy enables personalized preoperative planning. This paper reviews critical aspects of 3D printing for preoperative planning and surgical training, starting with an overview of the process-flow and 3D printing techniques, followed by their applications spanning across multiple organ systems in the human body. State of the art in these technologies are described along with a discussion of current limitations and future opportunities.

Three-dimensional (3D) printing technology allows for the translation of a 2-dimensional medical imaging study into a physical replica of a patient’s individual anatomy. 3D printed models can facilitate a deeper understanding of complex patient anatomy and can aid in presurgical decision-making.
Comparison between transthoracic echocardiography and cardiac magnetic resonance imaging in patients status post atrial switch procedure
March-April 2012 - Congenital Heart Disease
This study compares image quality, cost, right ventricular ejection fraction analysis, and baffle visualization between transthoracic echocardiography and cardiac magnetic resonance imaging in those status post atrial switch for transposition of the great arteries.
Increase of B-type natriuretic peptide from baseline increases the risk of death or retransplant in pediatric cardiac transplant patients, midterm results
May-June 2010 - Congenital Heart Disease
Several studies have demonstrated the utility of B-type natriuretic peptide (BNP) in the months following cardiac transplant. The purpose of this study was to analyze longitudinal BNP data in pediatric cardiac transplant patients and determine the efficacy of BNP in routine follow-up of transplant to help predict the adverse event of death or re-transplant.
Single pediatric center experience with multiple device implantation for complex secundum atrial septal defects
October 1, 2008 - Catheterization and Cardiovascular Interventions
We analyzed the efficacy and complications of placing multiple transcatheter devices to correct complex ASD in a primarily pediatric population.
