Valvuloplasty (or PTBV, percutaneous transluminal balloon valvuloplasty) is performed in the cardiac cath lab. This procedure treats hardened, narrowed heart valves. The procedure happens in 3 steps:
- An expandable balloon catheter is guided into your heart and positioned inside the narrowed valve.
- The balloon is inflated, which stretches the narrowed valve so that it can open more freely.
- The balloon catheter is deflated and withdrawn, and blood flows more easily through the treated valve.
