Professor of Surgery, Medicine, and Biomedical Engineering Washington University in St. Louis, School of Medicine Dr. Boineau has broad interests in both basic and clinical cardiac electrophysiology. Since 1963, he has been involved in mapping to determine the mechanisms of abnormal and complex electrocardiograms in myocardial infarction, ischemic cardiomyopathy, hypertrophy, congenital heart disease, and various different cardiac arrhythmias.  In the 1960s, he initiated arrhythmia ablation surgery with Dr. Will Sealy and worked out many of the basic substrates for a variety of arrhythmias, including those associated with myocardial infarction, preexcitation syndromes, atrial flutter and fibrillation.  Later, with Drs. James Cox and Richard Schuessler and others, he developed procedures for ablating atrial fibrillation, including the Maze and Radial procedures, and postoperative atrial flutter in patients with congenital heart defects.
