WBM Emergency & Critical Care

Decompensated aortic and mitral valve disease can present with pulmonary edema, impaired cardiac output, and cardiogenic shock. This masterclass reviews aortic stenosis, aortic regurgitation, mitral stenosis, and mitral regurgitation, connecting their distinct hemodynamics with clinical recognition and emergency management.

Topics covered include:
• Aortic stenosis: outflow obstruction and decompensation
• Aortic regurgitation: regurgitant flow and ventricular loading
• Mitral stenosis: impaired ventricular filling and pulmonary congestion
• Mitral regurgitation: left atrial pressure and reduced forward flow
• Acute presentations versus decompensated chronic valve disease
• Precipitating factors for clinical deterioration
• Preload, afterload, heart rate, rhythm, and cardiac output
• Pulmonary edema, pulmonary hypertension, and cardiogenic shock
• Clinical assessment and echocardiographic evaluation
• Volume management and diuresis considerations
• Rate control, vasoactive medications, and afterload considerations
• Respiratory support and hemodynamic stabilization
• Specialist evaluation and definitive valve intervention
• Comparing management priorities across the four valve lesions

The discussion emphasizes how stenosis and regurgitation affect circulation differently, providing a physiology-based framework for assessing and stabilizing decompensated valvular heart disease.

• Mitral stenosis and mitral regurgitation pathophysiology
• Hemodynamic differences between stenotic and regurgitant valve disease
• Acute versus chronic presentations and triggers for decompensation
• Left atrial pressure, pulmonary edema, and pulmonary hypertension
• Preload, afterload, heart rate, and cardiac output
• Atrial fibrillation and its hemodynamic consequences
• Ventricular function and cardiogenic shock
• Clinical recognition and echocardiographic evaluation
• Volume assessment and diuresis considerations
• Rate and rhythm management considerations
• Afterload reduction and vasoactive medication considerations
• Respiratory support and hemodynamic stabilization
• Specialist evaluation and definitive valve intervention
• Key differences in management priorities for mitral stenosis versus regurgitation

The discussion connects mitral valve physiology with clinical deterioration, emphasizing how the underlying lesion influences assessment, treatment selection, and stabilization priorities.

Decompensating mitral regurgitation requires recognition of pulmonary congestion, impaired forward cardiac output, and hemodynamic instability. This episode reviews mitral regurgitation physiology, acute versus chronic presentations, and emergency management considerations, connecting valvular dysfunction with pulmonary edema and cardiogenic shock.

Topics covered include:
• Mitral regurgitation anatomy and pathophysiology
• Acute versus decompensated chronic mitral regurgitation
• Regurgitant flow, left atrial pressure, and forward cardiac output
• Effects of preload, afterload, and ventricular function
• Causes and precipitating factors for decompensation
• Clinical recognition of pulmonary edema and cardiogenic shock
• Echocardiographic evaluation
• Volume assessment and diuresis considerations
• Afterload reduction and blood pressure considerations
• Respiratory support and hemodynamic stabilization
• Vasoactive medications and mechanical circulatory support considerations
• Specialist evaluation and definitive valve intervention

The discussion emphasizes how the timing and severity of mitral regurgitation influence clinical presentation, hemodynamics, and stabilization priorities.
