Question

List three conditions where marked diastolic abnormalities are observed with elevated ventricular filling pressures and symptoms of dyspnea or congestion despite normal systolic function.

Answer 1

Restrictive cardiomyopathy, constrictive pericarditis, and aortic stenosis are three conditions where marked diastolic abnormalities are observed with elevated ventricular filling pressures and symptoms of dyspnea or congestion despite normal systolic function.

Step-by-step explanation:

Marked diastolic abnormalities with elevated ventricular filling pressures and symptoms of dyspnea or congestion despite normal systolic function can be observed in the following conditions:

1. Restrictive cardiomyopathy: This condition is characterized by stiffening of the heart muscles, impairing its ability to relax and fill properly during diastole.
2. Constrictive pericarditis: In this condition, there is inflammation and scarring of the pericardium, the sac around the heart, leading to impaired diastolic filling.
3. Aortic stenosis: Narrowing of the aortic valve obstructs blood flow from the left ventricle into the aorta, causing increased ventricular filling pressures and symptoms like dyspnea and pulmonary congestion.
