What are the risks and recovery expectations for CRT-D implantation?

Risks are low but include infection at the implant site (1-2%), lead dislodgement, bleeding or pneumothorax (rare), and inappropriate shocks. Recovery involves 2-3 weeks of limited activity—no heavy lifting or vigorous arm movement on the implant side—with gradual return to normal routines. Most patients notice improved symptoms like reduced breathlessness and fatigue within weeks, though full benefit may take 3-6 months as device settings are optimized.
