Georgia Heart Institute Welcomes Three New Cardiologists

Published: Sunday, August 8, 2021

Georgia Heart Institute has always been known for leading the way in cardiovascular care. Now, with the addition of three new cardiologists, Georgia Heart Institute is experiencing growth in several key specialties. For patients needing heart and vascular services, that means there’s an even larger and stronger care team working together to ensure the best experience possible.

“To continue meeting the growing heart care needs of the communities we serve, the recruitment of highly-trained cardiologists is a top priority for our practice,” says Ryan Whitney, MD, FACC, president of Georgia Heart Institute. “With the addition of three cardiologists – one specializing in non-invasive cardiology, one in electrophysiology and one in heart failure cardiology – we’re providing an even higher level of care and expanding our capabilities throughout the region to get patients in more quickly.”

Among the three new cardiologists joining Georgia Heart Institute is David Weisman, MD, FHRS, an experienced electrophysiologist who specializes in comprehensive arrhythmia diagnosis and management. Dr. Weisman performs several forms of complex ablations and device implantations, including Watchman, and he participates in leading research and clinical trials.

Dr. Weisman received his medical degree from Mount Sinai School of Medicine in New York, New York. He subsequently went to Wake Forest University in Winston-Salem, North Carolina, to complete his residency. Dr. Weisman then completed his cardiovascular diseases and cardiac electrophysiology fellowships at Drexel College of Medicine in Philadelphia, Pennsylvania.

Most recently, Dr. Weisman has been working as an electrophysiologist in West Palm Beach, Florida, where he has also served as the Medical Director of the Electrophysiology Laboratory at Good Samaritan Medical Center. Dr. Weisman will see patients at Georgia Heart Institute location in Gainesville.

Georgia Heart Institute’s Advanced Heart Failure Program is proud to welcome Giancarlo Acosta, MD, FACC. Now, with four highly-trained cardiologists, this program has grown considerably and further enhanced its innovative care capabilities. As a part of the heart failure care team, Dr. Acosta specializes in diagnostics and ongoing disease management, ventricle assist device (VAD) patient selection and monitoring, as well as cardio-oncology care.

Dr. Acosta received his medical degree from Instituto Tecnologico de Santo Domingo in Dominican Republic. He subsequently went to Morristown Medical Center / Icahn School of Medicine at Mount Sinai in Morristown, New Jersey, to complete his residency and serve as Chief Resident. Dr. Acosta then finished his cardiology fellowship at Joan C. Edwards School of Medicine at Marshall University in Huntington, West Virginia, where he later served as Chief Fellow. Dr. Acosta joins Georgia Heart Institute from Baylor College of Medicine / Texas Heart Institute in Houston, Texas, where he completed his advanced heart failure & transplant cardiology fellowship.

Dr. Acosta speaks both Spanish and English, and he will be caring for patients at Georgia Heart Institute locations in Gainesville and Commerce.

Megan Smith, DO, joins the robust team of more than 20 non-invasive cardiologists at Georgia Heart Institute. As an expert who specializes in disease prevention and long-term heart care, Dr. Smith will provide a variety of services, including cardiovascular wellness screenings, disease management and diagnostic services, like echocardiography and nuclear imaging.

Dr. Smith received her medical degree from Lake Erie College of Medicine in Bradenton, Florida. She subsequently went to Manatee Memorial Hospital in Bradenton, Florida, to complete her internal medicine residency. She joins Georgia Heart Institute from The University of Kentucky in Bowling Green, Kentucky, where she completed her cardiovascular diseases fellowship. Dr. Smith will be caring for patients at Georgia Heart Institute’s location in Blairsville.

“We’re extremely proud to have these three new cardiologists join our team of leading heart experts,” says Habib Samady, MD, FACC, FSCAI. “Having providers, like Drs. Acosta, Smith and Weisman, who are not only highly trained and extremely skilled, but show compassion and dedication, is ultimately what ensures the best possible care for our patients each and every day.”
