Specialised Support for Cardiac and Sternal Recovery
Recovering from open-heart surgery, bypass procedures, or any operation requiring a median sternotomy demands rigorous attention to physical healing. During the crucial first six weeks post-surgery, protecting the breastbone and managing chest wall tension are vital to preventing complications and ensuring proper bone fusion.
Clinical-Grade Solutions Developed with NHS Experts
To bridge the gap between medical safety and everyday comfort, CUI Wear offers an award-winning range of cardiothoracic support garments designed alongside NHS clinical experts in cardiac surgery and surgical site infection prevention:
- The BHIS Post-Operative Support Bra: Engineered specifically for female patients, focusing on targeted lateral support rather than harsh downward compression. It features external seams, drain compatibility, and multi-hook front adjustments to relieve pressure near the base of the wound.
- The C.A.T.S. (Cardio Adjustable Thoracic Support) Unisex Vest: An innovative, adjustable vest designed for patients requiring stable rib cage and sternum splinting. It includes adjustable shoulder straps, breathable sports mesh back panels, and a unique utility pocket for telemetry wires or drainage equipment.
Why Standard Commercial Underwear Falls Short
Traditional bras and tight commercial compression wear are rarely suitable for the vulnerable post-operative chest. Underwires and downward pressure force tissue directly against the central incision, while tight pullovers require painful overhead stretching. Our dedicated clinical range eliminates these risks through front-fastening designs, skin-friendly external seams, and consistent, adjustable pressure that supports early mobilisation.

Frequently Asked Questions About Cardiac Support Wear
What is the difference between the BHIS Bra and the C.A.T.S. Vest?
The BHIS Bra is a specialised support bra engineered with side panels and cup sizing (28A to 56H) for female patients. The C.A.T.S. Vest is an adjustable, unisex thoracic support garment available in multiple chest depths and sizes (XS to 4XL) designed to act as a light splint for the rib cage and sternum.
When should I start wearing a post-operative support garment?
Patients typically begin wearing support garments as soon as they transition out of immediate hospital care or upon clinical clearance following a sternotomy. Early support helps stabilise the chest wall during initial rehabilitation and daily walks.
Do these garments accommodate chest drains or telemetry equipment?
Yes. Both garments are designed with medical practicalities in mind. The BHIS bra band accommodates standard chest drains, while the C.A.T.S. vest features a unique utility pocket with an exit hole for wires and monitoring equipment.
How do NHS hospitals procure these cardiothoracic garments?
Our cardiothoracic support range was developed alongside NHS clinical experts. NHS trusts and procurement teams can access our garments through institutional channels or by contacting our team directly for product evaluations and supply details.
How do I find the correct size for post-surgery swelling?
Our garments utilise flexible, breathable stretch fabrics designed to accommodate post-operative fluid retention and swelling without losing structural support. Comprehensive standard sizing is available across our bra ranges and unisex vest options.
