A heart valvuloplasty and stent valve deployment catheter assembly includes a single unitary catheter body having a proximal end and a distal end. The catheter body has a lumen extending between the proximal end and the distal end. A guide wire extends through the lumen proximally of the proximal end and distally of the distal end. A valvuloplasty balloon is disposed on the body. The balloon is located proximate to the distal end of the body. At least one radiopaque marker is disposed on the balloon. A valvuloplasty balloon inflation connection is located distally of the proximal end of the catheter body. A valvuloplasty inflation lumen extends partially through the catheter body and provides fluid communication between the valvuloplasty balloon inflation connection and the balloon. A stent valve is disposed over the body. The stent valve can be self-expanding or balloon expanding.
