Abstract
A two-part implantable heart valve and procedure are disclosed that allow expansion and positioning of a first part of the implantable heart valve having a temporary or transient valvular structure. A second part of the implantable heart valve is deployed within the first part and attaches thereto. The valvular structure of the second part then acts to function as the heart valve replacement. A tool or system is provided for determining an adequate percutaneous heart valve size for a given stenotic valve. A balloon can be inflated inside the stenotic valve to a desired pressure. When this pressure is reached an angiographic image is taken and the balloon diameter is measured at a waist area created by contact between the balloon and the stenotic valve. The diameter represents the minimum percutaneous heart valve diameter to be implanted.
