Cardiac Resynchronization Therapy (CRT) (Biventricular Pacemaker) | Heart and Stroke Foundation
The catheter is subsequently maneuvered to the opening of the coronary sinus in the right atrium. From here a contrast media is injected, allowing the surgical team to obtain a coronary sinus phleobogram to direct the placement of the lead into the most suitable coronary vein.
Once the phlebogram has been obtained, the multi-delivery catheter is used to guide in the lead, from the chosen vein of entry, into the right atrium, through the coronary sinus and into the relevant cardiac vein. Left ventricular lead placement is the most complicated and potentially hazardous element of the operation, due to the significant variability of coronary venous structure.
Cardiac resynchronization therapy
Alterations in heart structure, fatty deposits, valves and natural variations all cause additional complications in the process of cannulation. The device is inserted in a subcutaneous pocket created by the surgeon, the choice of left or right side of the chest wall is determined mainly by the patient's preference or location of preexisting device.
The device, similar to that of a traditional pacemaker , is generally no larger than a pocket watch and has inserts for the electrode leads. Key complications include: . Several research papers   have proposed software platforms for planning and guiding the implantation of CRT devices.
This research proposes using pre-operative images to characterize tissue and left ventricle activation to identify potential target regions for deploying the CRT leads.

Heart Failure Clinics. Journal of Cardiothoracic Surgery. November In cardiac resynchronization therapy CRT , a small electronic apparatus is surgically implanted to help both ventricles contract together.
Live Life to the Fullest
This device is made up of three leads which are attached to the heart muscle at one end one each to the right atrium, right ventricle and left ventricle and to a pulse generator at the other. The pulse generator is placed under a pocket of skin created either in the upper chest or the abdomen.
CRT is usually carried out in people with severe heart failure symptoms who are at risk of fast, irregular or life-threatening heart rhythms. If your heart does not contract effectively, it will not pump enough blood.
Cardiac Resynchronization Therapy
This is called poor ejection fraction. When medication options have been exhausted, this device helps by improving the heart function, quality of life, ability to exercise and survival. One of two approaches may be used to implant a CRT device. The procedure takes two to five hours. You may feel some discomfort at the implant site for the first 48 hours.

Tell your doctor or nurse if this is prolonged or if there is any pain. After you go home, your new device is monitored via transmitter, telephone monitoring and follow-up appointments.
Battery replacements, if required, can be carried out as an outpatient procedure. It takes a few weeks to resume normal activities after implantation. Before leaving the hospital, consult your doctor about directions on wound care, taking a shower generally not recommended until a few days later , moving, driving, exercise intensity, places or appliances to avoid and going back to work.
