The Aortic Annulus is the ring-like structure at the base of the aortic valve. It is the transition zone between the left ventricle and the aorta. Clinicians use the Aortic Annulus as a key reference point when assessing aortic valve disease. It is commonly discussed in echocardiography reports and in planning valve surgery or transcatheter valve procedures.

The Tricuspid Annulus is the fibrous and muscular “ring” that forms the base of the tricuspid valve. It sits between the right atrium (upper right chamber) and right ventricle (lower right chamber). Clinicians reference it in heart imaging, valve disease evaluation, and planning valve repair procedures. Its size and shape can change with the heartbeat and with certain heart conditions.

The Mitral Annulus is the fibrous, ring-like structure that forms the base of the mitral valve in the heart. It sits between the left atrium (upper chamber) and left ventricle (lower chamber). It anchors the mitral valve leaflets and helps them open and close efficiently. Clinicians commonly assess the Mitral Annulus on echocardiography and during mitral valve repair or replacement planning.

The Pulmonary Valve is one of the four valves in the heart. It sits between the right ventricle and the pulmonary artery. Its job is to keep blood moving forward from the heart to the lungs. Clinicians commonly assess it during heart exams and cardiac imaging.

The Pulmonic Valve is one of the four valves of the heart. It sits between the right ventricle and the pulmonary artery. Its job is to keep blood moving forward from the heart to the lungs. Clinicians commonly evaluate it when symptoms or imaging suggest right-sided heart or congenital heart conditions.

The Aortic Valve is one of the four valves inside the heart. It sits between the left ventricle (the main pumping chamber) and the aorta (the body’s main artery). It opens to let oxygen-rich blood leave the heart and closes to prevent blood from leaking backward. It is commonly discussed in echocardiograms, heart murmurs, and valve disease care.

The Tricuspid Valve is one of the four valves in the heart. It sits between the right atrium and the right ventricle. Its job is to keep blood moving forward and reduce backward flow. Clinicians commonly discuss it during cardiac exams, echocardiograms, and valve disease evaluations.

The Mitral Valve is a heart valve that sits between the left atrium and the left ventricle. It opens and closes with each heartbeat to help blood move forward in the correct direction. Clinicians refer to it when evaluating heart murmurs, shortness of breath, and heart failure symptoms. It is commonly assessed on echocardiography and may be treated with repair or replacement when diseased.

The Superior Mesenteric Vein is a major abdominal vein that drains blood from the small intestine and part of the large intestine. It is part of the portal venous system, which carries blood to the liver rather than directly back to the heart. Clinicians most often discuss it when evaluating abdominal pain, intestinal blood-flow problems, or portal vein conditions. It is commonly assessed on abdominal ultrasound and CT scans.

The Inferior Mesenteric Vein is a blood vessel that drains blood from the lower part of the large intestine. It is part of the portal venous system, which routes blood from the gut to the liver. Clinicians most often discuss it when interpreting abdominal imaging or planning abdominal surgery. It can also be relevant when evaluating blood clots, portal hypertension, or bowel inflammation.

The Portal Vein is a large vein that carries blood from the digestive organs to the liver. It collects nutrient-rich blood from the intestines, spleen, pancreas, and stomach. Clinicians commonly reference it in liver disease, abdominal vascular conditions, and advanced heart failure. It is often evaluated with ultrasound, CT, or MRI when portal hypertension or clot is suspected.

The Saphenous Vein is a superficial vein that runs along the leg and helps return blood back toward the heart. It includes the great saphenous vein and the small saphenous vein. In cardiovascular care, it is commonly discussed as a potential “conduit” (a vessel used as a tube) for bypass surgery. It is also assessed in venous disease, such as varicose veins and venous insufficiency.

The Popliteal Vein is a deep vein located behind the knee in the popliteal fossa. It carries blood from the lower leg upward toward the thigh and back to the heart. Clinicians commonly reference it when evaluating leg swelling, pain, and suspected blood clots.

The Femoral Vein is a large vein in the upper thigh that carries blood back toward the heart. It runs near the femoral artery and femoral nerve in the groin region. Clinicians often reference it in vascular exams, ultrasound studies, and catheter-based procedures. It is also a common access site for inserting catheters into the central veins.

The Subclavian Vein is a large vein that drains blood from the arm back toward the heart. It runs under the collarbone (clavicle) and joins other central veins in the upper chest. Clinicians commonly reference it for central venous access, device leads, and vascular imaging. It is also involved in certain clotting and compression conditions near the shoulder and chest.

Jugular Vein refers to the major veins in the neck that drain blood from the head and return it to the heart. In everyday cardiology and hospital care, clinicians often focus on the internal jugular vein and the external jugular vein. It is commonly discussed during physical exams (looking at neck vein fullness) and during placement of central venous lines. It is also important in imaging and procedures that need reliable access to the central circulation.

The Dorsalis Pedis Artery is a blood vessel on the top (dorsum) of the foot. It is commonly felt as the “top of the foot” pulse during a vascular exam. Clinicians use it to help assess blood flow to the lower leg and foot. It is also referenced in imaging and limb-salvage planning for peripheral artery disease.

The Tibial Artery refers to key arteries in the lower leg that carry oxygen-rich blood toward the ankle and foot. These vessels help supply the muscles of the calf and the tissues of the foot. Clinicians most often discuss them when evaluating leg circulation and wound healing. They are also important targets in imaging and procedures for peripheral artery disease.

The Popliteal Artery is a major blood vessel located behind the knee. It is the continuation of the femoral artery as it passes into the back of the knee. It supplies oxygen-rich blood to the lower leg and foot through its branches. Clinicians commonly discuss it when evaluating circulation problems in the legs.

The Femoral Artery is a large blood vessel that carries oxygen-rich blood to the thigh and lower leg. It is a continuation of the external iliac artery and runs through the groin into the upper thigh. Clinicians often assess it during vascular exams and use it as an access route for catheter-based procedures. It is also a common site for checking pulses and evaluating circulation to the legs.
