Non-invasive estimation of left ventricular systolic peak pressure: a prerequisite to calculate myocardial work in hypertrophic obstructive cardiomyopathy
Performance · LVSPResult — go to the resultCorrelation r 0.87Authors' conclusion
Non-invasive estimation of LVSP in HOCM is feasible by combining conventional BP and averaged CWmean and CWmax gradients.
Study context
- Population
- Patients with hypertrophic obstructive cardiomyopathy (HOCM) with indication for first alcohol septal ablation

- Comparison
- Non-invasively derived left ventricular systolic pressure (LVSP) vs invasively measured LVSP
- Outcome
- Agreement of non-invasively derived LVSP with invasively measured LVSP
Methodological detailsconsecutive patients, simultaneous invasive and non-invasive measurements

| Outcome | Values | P value |
|---|---|---|
| Mean gradient, CathLab vs CW Doppler | CathLab mean 34.3 (SD 13.4) mmHg · CW mean 31.0 (SD 13.7) mmHg | |
| Maximal gradient, echocardiography vs CathLabHigher in echocardiography | Echocardiography mean 64.5 (SD 28.8) mmHg · CathLab mean 54.8 (SD 24.0) mmHg | P < 0.05 |
Mean gradient, Catheterization Laboratory (CathLab) vs CW Doppler
- Mean gradients of both methods comparable
