Mammarella v. Evantash, M.D., et al.Annotate this Case
Barbara Mammarella sued her radiologist, Alan Evantash, M.D., her OB/GYN, Christine Maynard, M.D., and All About Women of Christiana Care, Inc. for medical malpractice. To establish her claim, Mammarella needed to present expert testimony that could support a jury verdict that the alleged negligence, which was a six-month delay in her breast cancer diagnosis, was the proximate cause of her injury, which was an alleged change in treatment that required Mammarella to undergo chemotherapy. Upon review of this case, the Supreme Court concluded that the testimony of Mammarella's sole medical expert on causation could not support a jury verdict because the expert did not testify to a reasonable degree of medical probability that Mammarella's treatment options had changed as a result of the alleged negligence. Therefore, the Supreme Court affirmed the Superior Court's grant of judgment as a matter of law in favor of the health care providers.
