Abstract
A method of repairing a heart valve provides intravascular access for repair of a heart valve through a ventricular trans-septal approach. An external guide catheter can be inserted through a vein of a patient into the right ventricle via the right atrium. An internal guide catheter can be inserted through the external guide and can provide access to the septum for a puncture tool to create an opening through the septum to the left ventricle. The internal guide can then be advanced into the left ventricle and used to guide a deployment catheter that deploys a repair device onto the heart valve.

A method of repairing a heart valve in a beating heart of a patient, comprising:
- inserting a guide catheter through a vein of a patient and into a right atrium of a heart of the patient;
- inserting a septal puncture tool through the guide catheter and into the heart;
- puncturing a septum in the patient's heart to create an opening through the septum;
- advancing a deployment catheter through the guide catheter and through the septum to a position adjacent a mitral valve leaflet;
- deploying a suture onto the mitral valve leaflet with the deployment catheter;
- inserting an anchor catheter through the guide catheter to insert an anchor device adjacent a left ventricle of the heart such that the suture extends from the mitral valve leaflet to the anchor device;
- adjusting a tension of the suture to achieve proper valve function;
- and
- locking the suture at the anchor device at the tension that achieves proper valve function.
