What is Cardiac Resynchronisation therapy?
Cardiac resynchronisation therapy is a common procedure offered to patients who suffer from heart failure for which drug management alone is not effective. The condition prevents the heart from beating regularly due to uncoordinated electrical activity. This means the organ struggles to circulate blood and oxygen around the body, resulting in patients straining with simple, everyday tasks.
The aim of the therapy is to resynchronize the contractions of the heart ventricles by implanting a device in the patient. Three pacing leads must be placed into the right atrium, the right ventricle, and the left ventricle of the patient’s heart which can deliver electrical signals to the heart muscle.
Lead placement for the left ventricle specifically has a critical influence on the procedure, and sub-optimal placement can cause poor outcomes in around 40% of cases. However, the optimal location is highly patient specific and can be affected by both anatomy and disease factors such as the presence of scar tissue.
