About Dr. Phillip A. Smith, MD, FACC

Dr. Phillip A. Smith, cardiologist at Cardiovascular Institute of the South

Phillip A. Smith, MD, FACC, is an interventional and structural heart cardiologist with Cardiovascular Institute of the South (CIS) in Baton Rouge and Zachary, Louisiana.

Dr. Smith treats people with heart valve disease, coronary artery disease, heart failure and related conditions. His focus is catheter-based procedures that repair or replace parts of the heart without open-heart surgery, along with the imaging needed to plan them well.

His medical education began in Louisiana. He earned a Bachelor of Science in biological sciences from Louisiana State University in Baton Rouge and his medical degree from the LSU School of Medicine in Shreveport, where he was named a Ronald B. George Scholar. He then spent eight years training at the University of Alabama at Birmingham (UAB): internal medicine residency in the Tinsley Harrison program, where he received the Cobbs Award, followed by fellowships in cardiovascular disease, interventional cardiology and structural heart disease.

During training he volunteered at the PATH Clinic, a free primary care clinic for uninsured residents of Jefferson County, Alabama. In 2020 he served as a cardiology consultant and proceduralist in UAB's COVID-19 intensive care units during the pandemic surge. His research on nuclear stress imaging and on an unusual form of stress-related heart muscle weakness was published in the Journal of Nuclear Cardiology and Echocardiography.

Dr. Smith joined CIS in August 2023. Since then he has been primary operator for more than 180 structural heart procedures, including more than 85 transcatheter aortic valve replacements (TAVR), transcatheter mitral and tricuspid repair, left atrial appendage occlusion, PFO and ASD closure, balloon valvuloplasty, paravalvular leak closure and alcohol septal ablation. In 2025 he performed Baton Rouge General's first successful paravalvular leak closure. In 2026 he performed the hospital's first TriClip and started its transcatheter tricuspid repair program.

His work reaches beyond valves. At Baton Rouge General he implants CardioMEMS heart failure sensors and leads the practice's remote pressure-monitoring program. He also co-designed the hospital's heart attack cardiogenic shock pathway, from EMS pre-alert through temporary heart pump support and ICU care. At Lane Regional Medical Center in Zachary, he helped start the pulmonary embolism thrombectomy program and proctored the hospital's interventional cardiologists, who now perform the procedure on their own. He performs coronary angiography, angioplasty and stenting, including emergency heart attack care.

Imaging is central to structural heart care. In addition to cardiovascular disease and interventional cardiology, Dr. Smith is board certified in echocardiography, nuclear cardiology and cardiac CT. He performs transesophageal, transthoracic and intracardiac echocardiography and reads nuclear stress tests and cardiac CT scans.

Dr. Smith sees patients at the CIS clinics on Picardy Avenue in Baton Rouge and on Main Street in Zachary, where he serves northern East Baton Rouge Parish and nearby rural communities, including in Mississippi. He holds active staff privileges at Baton Rouge General Medical Center – Bluebonnet, Our Lady of the Lake Regional Medical Center and Lane Regional Medical Center.

He also teaches. He has spoken at the New Cardiovascular Horizons conference in New Orleans on TAVR, valve treatments and left atrial appendage closure; presented "Structural Heart 101: Key Insights for PCPs" to the Louisiana Academy of Family Physicians; and returned to UAB to speak with interventional and structural heart fellows about the first year of practice.

Dr. Smith is a Fellow of the American College of Cardiology and a member of the Society for Cardiovascular Angiography and Interventions and the American College of Physicians.
