New tool for helping pediatric heart surgery
Date:11/23/2009

tional tool to assist in this process. In addition, Dr. Marsden and cardiologist Jeff Feinstein have developed a new Y-graft design for the Fontan surgery that is expected to be put into clinical use within a few months.

"Our ultimate goal is to optimize surgeries that are tailored for individual patients so that we don't have to rely on a "one-size fits all" solution," says Marsden.

The tool first uses imaging data to construct a model of an individual baby's heart and then allows doctors to input their surgical designs. The computer can then systematically explore different potential designs using powerful optimization algorithms, similar to those used in the aerospace industry for aircraft design. It then applies fluid dynamics to simulate the blood flow after reconstruction. This way, says Marsden, surgeons can test their plans and evaluate blood flow patterns before operating.

The talk " Analysis of Alternative Polling Strategies for Derivative-Free Optimization of the Fontan Surgery" by Weiguang Yang, Jeffrey Feinstein, and Alison Marsden is at 12:06 p.m. on Tuesday, November 24, 2009.
