VENTRICULAR MARGINS Figure 1-15 VENTRICULAR MARGINS The two sides of the right ventricular free wall form an acute angle that represents a well-defined acute margin (yellow arrow). Opposite this, however, the left ventricular free wall is rounded, such that tangential lines form an obtuse angle More about this image found in VENTRICULAR MARGINS The two sides of the right ventricular free wall form ...

VENTRICULAR SEPTAL RUPTURE Figure 8-8 VENTRICULAR SEPTAL RUPTURE A large, transmural, apical and mid-ventricular infarction with an associated septal rupture (yellow arrows) causes an acquired ventricular septal defect. More about this image found in VENTRICULAR SEPTAL RUPTURE A large, transmural, apical and mid-ventricular...

VENTRICULAR SEPTAL RUPTURE: TYPES Figure 8-9 VENTRICULAR SEPTAL RUPTURE: TYPES A simple ventricular septal rupture (left; yellow arrows) is linear (through-and-through) while a complex ventricular septal rupture (right; yellow arrow) is serpiginous, meandering through the wall of the septum More about this image found in VENTRICULAR SEPTAL RUPTURE: TYPES A simple ventricular septal rupture (lef...

LEFT VENTRICULAR TRUE ANEURYSM Figure 8-15 LEFT VENTRICULAR TRUE ANEURYSM Left: The left ventricular contour (yellow arrow) bulges beyond its expected lateral border. Right: The true aneurysm has a wide neck (yellow arrows) in which the uninvolved myocardium tapers to join the infarcted More about this image found in LEFT VENTRICULAR TRUE ANEURYSM Left: The left ventricular contour (yellow ...

PULMONARY HYPERTENSION: RIGHT VENTRICULAR HYPERTROPHY Figure 20-9 PULMONARY HYPERTENSION: RIGHT VENTRICULAR HYPERTROPHY This mid-ventricular short-axis section exhibits some right ventricular chamber dilatation with prominent wall thickening. The right ventricle is nearly as thick as the left More about this image found in PULMONARY HYPERTENSION: RIGHT VENTRICULAR HYPERTROPHY This mid-ventricular...

LEFT VENTRICULAR DIVISIONS Figure 1-6 LEFT VENTRICULAR DIVISIONS The base-apex length is di vided into thirds. The basal third cor responds to mitral leaflets and their tendinous cords, and the middle third contains the mitral papillary muscles. The apical third has no mitral components. More about this image found in LEFT VENTRICULAR DIVISIONS The base-apex length is di vided into thirds. T...

16 LEFT VENTRICULAR SEGMENTS Figure 1-17 16 LEFT VENTRICULAR SEGMENTS There are six segments at the basal level, six at the mid-ventricular level, and four at the apical level. Sometimes the tip of the apex is labeled as segment 17. Their use facilitates documentation of the location and size More about this image found in 16 LEFT VENTRICULAR SEGMENTS There are six segments at the basal level, si...
