A Cook County jury was deadlocked after four days of deliberation in a case in which the plaintiff claimed she underwent an unnecessary coronary bypass surgery. Maryann Giannetti was 52 years old when she underwent a stress test at St. Joseph Hospital in Chicago. She claimed she was suffering “vague” chest tightness on Aug. 14, 2006. During the stress test, she experienced ventricular tachycardia, which can be potentially fatal because of the irregular heartbeat or arrhythmia. She experienced this condition while on a treadmill. A coronary angiogram was ordered.
The defendant, Dr. Uday Vyas, a cardiologist, and the defendant cardiothoracic surgeon, Dr. William Bradshaw, interpreted the angiogram. They believed the angiogram showed 50% to 60% blockage of the opening of the left main coronary artery and 70% blockage of the proximal circumflex artery.
Because of the findings of blockage, the doctors ordered Giannetti to have a double coronary bypass surgery. She was never convinced that she needed the surgery and later showed the films to another cardiologist who told her there was no blockage whatsoever of any artery.
