CIS & OGHS Install Zero-Gravity Radiation System

OPELOUSASOn April 5, Cardiovascular Institute of the South (CIS) and Opelousas General Health System (OGHS) installed the Biotronik Zero-Gravity Suspension Radiation Protection Unit in the cardiac catheterization laboratory, providing a more effective method of protecting cardiologists from radiation exposure moving forward.

This ceiling-mounted unit provides an 87-100% reduction in radiation exposure as compared to conventional lead aprons with table shields and movable shields.  It also eliminates the need for physicians to wear heavy lead protective apparel, which can cause neck and back strain over time.  Additionally, the suspended unit offers freedom of movement and is easily engaged or disengaged depending on the use of x-ray imaging.

“Occupational radiation exposure and orthopedic injury is a growing concern among interventional cardiologists,” explained Dr. Robert Menuet, interventional cardiologist at CIS.  “The zero gravity system is state-of-the-art and the first of its kind in Acadiana, proving that OGHS is far ahead of its peers by investing in the best that technology has to offer to its physicians.”

“This is the only tool in the cath lab that protects and likely prolongs the career and life of cardiologists!” said Dr. Kalyan Veerina, CIS interventional cardiologist.  “It’s a game changer.”


Zero-Gravity utilizes a suspended 1.0 mm lead body shield that engages magnetically to a vest worn by the operator.  This allows it to move in sync with the operator and easily be stored out of the way when not needed.  In addition, it employs a 0.5 mm lead equivalent acrylic face shield that protects the head, eyes and throat of the operator.

CIS interventional cardiologist Dr. David Homan said, “Zero-Gravity will allow me to provide exceptional care to my patients without jeopardizing my own health and career.  It’s a win-win for both patients and docs.”

CIS and OGHS partner to utilize the most advanced technology, such as atherectomy, specialty balloons and stents, to offer minimally invasive options for high-risk heart disease patients.  Additionally, CIS’s extensive experience in interventional cath lab procedures can save patients from amputation and improve overall quality of life.  To learn more, call 337-942-3006 or visit
