This chapter examines some of the challenges of cardiac resynchronization therapy (CRT). The procedure continues to be technically difficult and in recent years there have been advances in technology that have helped successful implantation and response to the therapy. A methodical approach to left ventricular lead placement is described in the chapter, along with troubleshooting guidance for the difficult case. Technological developments such as quadripolar leads have changed practice and so this is described in detail. New concepts of CRT are emerging such as left ventricular endocardial pacing and left ventricular only pacing. Appropriate follow-up of patients following implantation is important. All of these clinical issues are described in this chapter, ensuring a comprehensive practical guide to all aspects of CRT.
