Effects of incoordination on left ventricular force-velocity relation in aortic stenosis.
OBJECTIVE: Tension development is often incoordinate in the hypertrophic left ventricle (LV). The present study aimed to elucidate the possible effects of incoordination on standard LV force-velocity relations in patients with aortic stenosis (AS). DESIGN: Prospective study during aortic valve replacement with transoesophageal cross sectionally guided M mode echocardiogram, combined with high-fidelity LV pressure recorded by pressure transducer tip catheter, and thermodilution cardiac output....Expand abstract
