ANATOMIC RELATIONSHIPS OF FETAL ADRENAL GLANDS Figure 1-6 ANATOMIC RELATIONSHIPS OF FETAL ADRENAL GLANDS Transverse section of upper abdomen in a fetus of about 10 weeks’ gestational age. Liver is at the top left side of the image, pancreas at top right. The developing para-aortic and preaortic n...

FETAL ADRENAL GLAND AND KIDNEY Figure 1-5 FETAL ADRENAL GLAND AND KIDNEY Coronal section of adrenal kidney and adjacent tissue from a fetus at approximately 11 weeks’ gestational age. The developing para-aortic sympathetic plexus has a close relationship with the medial and inferior aspects of th...

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 in these lesions (C) (GMS stain).

AORTIC ORIGIN OF CONUS CORONARY ARTERY FROM RIGHT AORTIC SINUS Figure 1-36 AORTIC ORIGIN OF CONUS CORONARY ARTERY FROM RIGHT AORTIC SINUS The ostium lies anterior to the right coronary artery ostium (leftward in the specimen). (Aortic valve, opened through its left cusp.) More about this image found in AORTIC ORIGIN OF CONUS CORONARY ARTERY FROM RIGHT AORTIC SINUS The ostium ...

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 o... More about this image found in FIBROCALCIFIC AORTIC VALVE DISEASE This aortic valve, surgically resected ...

CONGENITALLY BICUSPID AORTIC VALVE: NO RAPHE Figure 9-10 CONGENITALLY BICUSPID AORTIC VALVE: NO RAPHE Congenitally bicuspid aortic valves without a raphe often have equal-sized cusps with identical morphology and two discrete aortic sinuses. More about this image found in CONGENITALLY BICUSPID AORTIC VALVE: NO RAPHE Congenitally bicuspid aortic ...

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.

AORTIC ANNULAR DILATATION Figure 10-13 AORTIC ANNULAR DILATATION The aortic valve annulus is markedly dilated (compared to the fairly normal pulmonary valve [PV]), such that the cusps no longer coapt in the middle (yellow arrow). More about this image found in AORTIC ANNULAR DILATATION The aortic valve annulus is markedly dilated (co...

AORTIC ANNULAR DILATATION Figure 10-14 AORTIC ANNULAR DILATATION Surgically excised aortic valve cusps show stretching and thinning (increased translucency). The approximate annular diameter exceeds 4 cm. More about this image found in AORTIC ANNULAR DILATATION Surgically excised aortic valve cusps show stret...

SACCULAR ABDOMINAL AORTIC ANEURYSMS Figure 28-3 SACCULAR ABDOMINAL AORTIC ANEURYSMS While abdominal aortic aneurysms may look somewhat fusiform when viewed from an anterior perspective, viewing the vessel in profile (sagittal plane) (left; yellow arrow) or with cross-sectional imaging (above), sh...

ANNULAR DILATATION CAUSING AORTIC REGURGITATION Figure 28-19 ANNULAR DILATATION CAUSING AORTIC REGURGITATION Ascending aortic dilatation may cause the aortic valve annulus to dilate, which may stretch the valve cusps and lead to cusp malcoaptation (yellow arrow) and regurgitation.
