Disease states
Where to select each condition and what the scenario illustrates.
Hypertrophic Obstructive Cardiomyopathy
Dynamic LV outflow obstruction with impaired filling and an illustrative spike-and-dome arterial contour.
Hypovolemic Shock
Reduced circulating volume lowers venous return and filling pressures, producing low output and hypotension.
Ischemic Cardiomyopathy
Chronic ischemic LV systolic dysfunction with reduced forward output and elevated left-sided filling pressures.
Left Atrial Myxoma
Selected mobile left atrial myxoma with intermittent mitral inflow obstruction. LA pressure rises upstream while LV filling and beat stroke volume vary; displayed reference pressures and CO are multi-beat means.
Mitral Valve Prolapse
Chronic severe prolapse-related MR with modest mean LA pressure elevation, a regurgitant v wave and preserved resting forward flow. Loading maneuvers alter the modeled prolapse/MR burden.
Neurogenic Shock
Loss of sympathetic tone produces vasodilation, reduced venous return and relative bradycardia.
Precapillary Pulmonary Hypertension
High pulmonary artery pressure with a preserved wedge pressure.
Preserved
Follow the pressure change as the catheter moves through the right heart.
Restrictive Cardiomyopathy
Elevated biventricular filling pressures with rapid early filling followed by a dip-and-plateau contour.
Septic Shock
An illustrative hyperdynamic septic shock profile: low systemic resistance with high forward flow.
Severe Aortic Stenosis
Severe AS with fixed LV outflow obstruction, a narrow pulse pressure at 115/85 mmHg, and impaired LV relaxation. LVEDP is mildly elevated, wedge is near its upper reference limit, and PVR is normal at baseline.
Severe LVH · Preserved EF
Severe concentric LV hypertrophy with preserved reference ejection fraction, impaired relaxation and elevated left-sided filling pressures. This selected nonobstructive phenotype has adequate resting forward flow and systemic blood pressure.
Severe Mitral Stenosis
Severe MS raises LA/wedge pressure upstream of the stenotic valve while LVEDP remains near normal. This baseline shows passive postcapillary pressure elevation, without pulmonary vascular remodeling.
Severe Pulmonic Regurgitation
Pulmonary diastolic runoff with RV volume overload and elevated right-sided filling pressure.
Severe Pulmonic Stenosis
RV systolic pressure is much higher than PA systolic pressure across the obstructed pulmonic valve.
