Background: It remains unknown whether patients with severe decompensated class IV heart failure (HF) receiving intravenous inotropic treatment benefit from cardiac resynchronization therapy (CRT).
Methods: We identified patients who underwent urgent CRT implantation due to decompensated class IV HF necessitating intravenous inotropic therapy.
Results: Of 10 patients with chronic ischemic cardiomyopathy (median QRS duration of 170 ms), CRT implantation was associated with symptomatic improvement in 8 patients. The mortality rate was 50% during a median follow-up of 9.5 months, with a median CRT-to-death duration of 6 months.
Conclusions: CRT was feasible among class IV patients receiving inotropic treatment and was associated with clinical improvement.
