Observation
Mitral Valve: Leaflet thickness and mobility are normal. Trace mitral regurgitation is detected. No mitral stenosis.
Aortic Valve: The aortic valve is trileaflet. There is aortic valve sclerosis without evidence of stenosis. Mild aortic calcification. No aortic regurgitation is detected.
Tricuspid Valve: Leaflet thickness and mobility are normal. Moderate tricuspid regurgitation is detected. Right ventricular systolic pressure is elevated at 38 mmHg, which is mildly elevated pulmonary pressures.
Pulmonic Valve: The pulmonic valve is normal in structure and function. No pulmonic valve stenosis is detected. Mild pulmonic regurgitation is detected.
Left Atrium: The left atrial volume index is severely increased. The interatrial septum is aneurysmal.
Left Ventricle: Normal left ventricular cavity size, wall thickness, and systolic function. The estimated left ventricular ejection fraction is 60-65%. No regional wall motion abnormalities are detected. Grade 2 diastolic dysfunction is present.
Right Atrium: The right atrium is normal in size.
Right Ventricle: Normal right ventricular cavity size and systolic function.
Pericardium: There is no pericardial effusion.
Pleura: No significant pleural effusion is detected.
Miscellaneous: The IVC is less than 2.1 cm and is > 50% collapsible consistent with a right atrial pressure of approximately 3 mmHg. The aortic root diameter is normal.
