Crt lead placement based on optimal branch selection and optimal site selection

One or more computer-readable media comprising processor executable instructions to instruct a computing device to:

• access cardiac information acquired via a catheter located at various positions in a coronary sinus of a patient wherein the cardiac information comprises electrical information and mechanical information;
• calculate scores based on the cardiac information wherein each of the scores corresponds to the coronary sinus or a tributary of the coronary sinus;
• and,
• based on the scores, select a tributary of the coronary sinus as an optimal candidate for placement of a left ventricular lead.

A method comprising:

• accessing cardiac information acquired via a catheter located at various positions in a coronary sinus of a patient wherein the cardiac information comprises electrical information and mechanical information;
• mapping the electrical information and the mechanical information to a composite map wherein the composite map includes a geometric representation of at least the coronary sinus;
• and,
• based on the composite map, selecting a tributary of the coronary sinus as an optimal candidate for placement of a left ventricular lead.

One or more computer-readable media comprising processor executable instructions to instruct a computing device to:

• access cardiac information acquired via a catheter located at various positions in a coronary sinus of a patient wherein the cardiac information comprises electrical information and mechanical information;
• map the electrical information and the mechanical information to a composite map wherein the composite map includes a geometric representation of at least the coronary sinus;
• and,
• based on the composite map, select a tributary of the coronary sinus as an optimal candidate for placement of a left ventricular lead.

A method comprising:

• accessing a ranking of tributaries of the coronary sinus wherein the ranking ranks the tributaries as candidates for placement of a left ventricular lead;
• acquiring information via a left ventricle lead for various locations in a selected tributary;
• mapping the acquired information, or one or more metrics derived from the acquired information, to a map wherein the map includes a geometric representation of at least a portion of the selected tributary;
• based on the map, optimally placing the left ventricular lead in the selected tributary.

One or more computer-readable media comprising processor executable instructions to instruct a computing device to:

• access a ranking of tributaries of the coronary sinus wherein the ranking ranks the tributaries as candidates for placement of a left ventricular lead;
• select the highest ranked tributary;
• acquire information via the left ventricle lead for various locations in the selected tributary;
• map the acquired information or one or more metrics derived from the acquired information to a map wherein the map includes a geometric representation of at least a portion of the selected tributary;
• based on the map, optimally place the left ventricular lead in the selected tributary.
