LV pacing may alleviate external constraint in advanced HF; hypothesis-generating case series leaves benefit open pending randomized trials.
Does left ventricular pacing reduce external constraint to LV filling and improve hemodynamics in heart failure patients with NYHA class III/IV limitation?
Left ventricular pacing in heart failure patients minimizes external constraint to LV filling, which increases effective filling pressure and stroke volume via the Starling mechanism.
Bleasdale et al. (2004) studied this question.
