LV size-end systole: 3.2 cm.
LV size-end diastole: 4.6 cm.
LV post wall thick diastole: 1.0 cm.
IV septal wall thick diastole: 0.8 cm.
Ao root dia.: 3.1 cm.
Ao valve open: 2.5 cm. Those are the measurements of my dear, sweet, warm, bloody, beating heart. I recently participated in a cardiac study (as a free way of determining how much damage 10 years of cigarettes and adulterated street drugs had done to my poor ticker). The results were pleasantly astonishing (I have some ubertough cardiac DNA). I thought all those uppers would have thickened my heart significantly, but alas, no! Here's the final report, for the record: Left ventricular internal dimensions are normal at end systole and end diastole.
Left ventricular wall thickness is within normal limits.
The left ventricular systolic function is normal with no regional wall motion abnormalities identified.
The ejection fraction is 65% by biplane method of disks.
The left atrium is normal in size.
The mitral valve appears normal in structure and function.
The aortic valve is trileaflet and displays normal ability.
The aortic root is not dilated. The tricuspid valve appears normal in structure and function. The right-sided chambers do not appear enlarged. The pulmonic valve is not well visualized. There is no pericardial effusion or intracavity mass.
