Which structure, located in the right atrium, is a congenital remnant of the right valve of the sinus venosus?

On echocardiography, if the inferior vena cava (IVC) is IVC ≤ 2.1 cm + >50% collapse with a sniff, what is the estimated right atrial (RA) pressure?

Systolic anterior motion (SAM) of the mitral valve is a hallmark finding in hypertrophic obstructive cardiomyopathy (HOCM). Which mechanism primarily causes SAM during systole?

A patient with chronic hypertension undergoes echocardiography. Findings reveal an enlarged left ventricular (LV) cavity, normal wall thickness, and increased LV mass. Which pattern of hypertensive heart disease does this most likely represent?

A patient’s echocardiogram demonstrates a left atrial (LA) end-systolic volume index of 72 mL/m². What is most likely to occur with this degree of left atrial enlargement?

Review the SAX images. Which of the following is most consistent with this image?
