Valve Replacement: Definition, Uses, and Clinical Overview

Valve Replacement is a treatment that swaps a diseased heart valve for an artificial or donor valve. It is used when a valve cannot open or close properly and blood flow becomes inefficient or backward. It is commonly performed for aortic or mitral valve disease, and less often for tricuspid or pulmonary valve disease. It may be done through open-heart surgery or with catheter-based (transcatheter) techniques.

Off-Pump CABG: Definition, Uses, and Clinical Overview

Off-Pump CABG is a form of coronary artery bypass grafting performed while the heart is still beating. It is used to restore blood flow to heart muscle when coronary arteries are narrowed or blocked. Instead of a heart–lung machine, surgeons use specialized stabilizers to operate on moving heart tissue. It is commonly performed in cardiothoracic surgery centers that offer surgical treatment for coronary artery disease.

MEP: Definition, Uses, and Clinical Overview

MEP stands for **motor evoked potentials**. MEP testing measures how well **motor (movement) signals travel from the brain, through the spinal cord, to the muscles**. MEP is commonly used during **spine surgery** as part of intraoperative neuromonitoring. It can also be used in specialized neurophysiology settings to evaluate motor pathway function.

Motor evoked potentials: Definition, Uses, and Clinical Overview

Motor evoked potentials are electrical signals recorded from muscles after the nervous system is stimulated. They reflect how well motor pathways carry messages from the brain and spinal cord to the limbs. They are commonly used during spine and brain surgery as part of intraoperative neuromonitoring. They can also be used in select diagnostic settings to assess motor pathway function.

Somatosensory evoked potentials: Definition, Uses, and Clinical Overview

Somatosensory evoked potentials are electrical signals recorded from the nervous system after a small, controlled sensory stimulus. They help show whether sensory pathways from the arms or legs to the spinal cord and brain are conducting normally. They are commonly used in neurodiagnostic testing and in the operating room during spine and brain procedures. They do not treat a condition; they measure nerve pathway function.

Coronary Bypass Surgery: Definition, Uses, and Clinical Overview

Coronary Bypass Surgery is an operation that restores blood flow to heart muscle when coronary arteries are narrowed or blocked. It works by creating a new route (“bypass”) for blood to reach the heart beyond the blockage. It is most commonly used to treat advanced coronary artery disease that causes symptoms or threatens heart function.

Nerve conduction study: Definition, Uses, and Clinical Overview

A Nerve conduction study is a diagnostic test that measures how well electrical signals travel through peripheral nerves. It uses small surface electrodes and brief electrical pulses to record nerve responses. It is commonly used to evaluate numbness, tingling, weakness, and suspected nerve compression in the arms or legs. It is often performed alongside electromyography (EMG) to give a fuller picture of nerve and muscle function.

IVL: Definition, Uses, and Clinical Overview

IVL most commonly refers to **intravascular lithotripsy** in cardiovascular medicine. It is a **catheter-based technique** used to treat **hard, calcified plaque** inside arteries. IVL is commonly used during **coronary** (heart) or **peripheral** (leg and other) endovascular procedures. Its goal is to make a narrowed, calcified artery more treatable with balloons and stents.
