Implication

Low upgrade rates may signal CRT underutilization; leaves open whether broader initial implant criteria improve outcomes.

Structured PICO

Population

549 patients receiving new implantable cardioverter defibrillator (ICD) implants over 5 years (2003-2007), including 399 with single- or dual-chamber ICDs and 150 with CRT-D.

Outcome

Rate of cardiac resynchronization therapy (CRT) upgrade during follow-up

The rate of upgrading from a single- or dual-chamber ICD to CRT in clinical practice is low (3.8% over ~4 years), suggesting potential underutilization compared to broader initial implant criteria.
