The Spectranetics Excimer Laser can be used in which of the following?

• A. Coronary arteries and pacemaker lead extractions
• B. Renal arteries and hepatic arteries
• C. Pulmonary arteries and cerebral arteries
• D. Aorta repair

Answer: (A)

The Spectranetics Excimer Laser is designed for two main uses: laser-assisted lead extraction and laser-assisted coronary plaque modification. In lead extraction, the 308 nm ultraviolet laser energy helps disrupt fibrous tissue around pacemaker or defibrillator leads, allowing safe removal with less traction. In the coronary setting, it can ablate or modify calcified plaque to facilitate ballooning and stenting, especially in complex lesions. It is not used for renal or hepatic arteries, pulmonary or cerebral arteries, or for aorta repair, so the combination that fits its approved applications is coronary arteries and pacemaker lead extractions.
