HISTOPLASMA ENDOCARDITIS Figure 23-7 HISTOPLASMA ENDOCARDITIS A: This most often affects the left heart valves, particularly the aortic valve. B,C: There is often underlying valvular disease and organisms usually appear enmeshed in fibrin (B). Short hyphal forms may be seen More about this image found in HISTOPLASMA ENDOCARDITIS A: This most often affects the l...

INFECTIVE ENDOCARDITIS VEGETATIONS Figure 16-3 INFECTIVE ENDOCARDITIS VEGETATIONS Multiple, friable, yellow-tan infective endocarditis vegetations involve the mitral valve.

AORTIC VALVE SCLEROSIS Figure 9-1 AORTIC VALVE SCLEROSIS Thickening of the aortic valve cusps is usually an age-related phenomenon and is not usually associated with significant dysfunction. The valve has lost its normal translucent character. More about this image found in AORTIC VALVE SCLEROSIS Thickening of the aortic valve cusps is usually an ...

FIBROCALCIFIC AORTIC VALVE DISEASE Figure 9-3 FIBROCALCIFIC AORTIC VALVE DISEASE This aortic valve, surgically resected in the setting of severe stenosis, shows the distribution of disease from the base of the cusp over the surface (upper image). The arc-like pattern of calcification is evident More about this image found in FIBROCALCIFIC AORTIC VALVE DISEASE This aortic valve, surgically resected ...

FIBROCALCIFIC AORTIC VALVE DISEASE: QUADRICUSPID TYPE Figure 9-20 FIBROCALCIFIC AORTIC VALVE DISEASE: QUADRICUSPID TYPE Four aortic valve cusps, including a supernumerary cusp (right), are seen with fibrocalcific disease.

PROSTHETIC VALVE THROMBOSIS Figure 9-35 PROSTHETIC VALVE THROMBOSIS Left: Bioprosthetic valve thrombosis manifests as a red-pink adherent thrombus, usually depositing within the cusp pockets. Right: Mechanical thrombus may be less adherent but has a similar appearance. More about this image found in PROSTHETIC VALVE THROMBOSIS Left: Bioprosthetic valve thrombosis manifests...

MYXOMATOUS MITRAL VALVE DISEASE Figure 10-1 MYXOMATOUS MITRAL VALVE DISEASE The mitral valve is prominent and billowing in a diffuse fashion, with prominent annular dilatation. Valve translucency is completely lost with the myxomatous thickening. More about this image found in MYXOMATOUS MITRAL VALVE DISEASE The mitral valve is prominent and billowin...

BIOPROSTHETIC VALVE: CUSP AVULSION Figure 10-26 BIOPROSTHETIC VALVE: CUSP AVULSION The prosthetic valve cusps have avulsed from their post, causing marked prosthetic regurgitation. More about this image found in BIOPROSTHETIC VALVE: CUSP AVULSION The prosthetic valve cusps have avulsed...

HYPERTROPHIC CARDIOMYOPATHY: MITRAL VALVE CHANGES Figure 15-9 HYPERTROPHIC CARDIOMYOPATHY: MITRAL VALVE CHANGES The mitral valve may be morphologically abnormal which can lead to abnormal hemodynamics causing fibrotic mitral valve thickening. If systolic anterior motion is present, it may More about this image found in HYPERTROPHIC CARDIOMYOPATHY: MITRAL VALVE CHANGES The mitral valve may be ...

QUADRICUSPID AORTIC VALVE Figure 36-15 QUADRICUSPID AORTIC VALVE Left: Fibrotic but only minimally calcific valve, with normal function (for comparison with above), in an elderly adult. Above: Severely calcified and stenotic valve, in an elderly adult (surgical specimen). More about this image found in QUADRICUSPID AORTIC VALVE Left: Fibrotic but only minimally calcific valve...

EBSTEIN ANOMALY: TRICUSPID VALVE REPLACEMENT Figure 39-15 EBSTEIN ANOMALY: TRICUSPID VALVE REPLACEMENT The bioprosthetic valve is intact and well seated, in a middle-aged adult. A prominent muscular ridge (white arrow) contains small remnants of the anterior and septal leaflets. The right More about this image found in EBSTEIN ANOMALY: TRICUSPID VALVE REPLACEMENT The bioprosthetic valve is in...
