Low profile transseptal catheter and implant system for minimally invasive valve procedure

A delivery assembly comprising:

• at least one introducer sheath;
• a first guide catheter and a first guide wire insertable through the first guide catheter for forming a posterior loop around a first leaflet of a native heart valve;
• a second guide catheter and a second guide wire insertable through the second guide catheter for forming an anterior loop around a second leaflet of a native heart valve;
• a first tubular leaflet brace slidable over the posterior loop formed by the first guide wire;
• a second tubular leaflet brace slidable over the anterior loop formed by the second guide wire;
• a first fastening catheter and a first fastener, wherein the first fastening catheter is configured to frictionally couple the first fastener with a first end portion of each of the first tubular brace and the second tubular brace;
• a second fastening catheter and a second fastener, wherein the second fastening catheter is configured to frictionally couple the second fastener with a second end portion of each of the first tubular brace and the second tubular brace;
• a prosthetic heart valve;
• and
• a valve delivery catheter having the prosthetic heart valve coupled to a distal end portion thereof in a radially compressed state.

A delivery assembly comprising:

• at least one introducer sheath;
• a first guide catheter and a first guide wire insertable through the first guide catheter;
