Orbital atherectomy for calcified heart blockages

This study is testing a technique to treat heavily calcified (hard) blockages in heart arteries. The goal is to see if a special way of preparing the blockage before placing a stent helps improve blood flow to the tiny blood vessels in the heart muscle.

This trial compares a special device called orbital atherectomy to the usual procedure for treating hardened, calcified blockages that occur where a coronary artery branches. It aims to see which approach works better for patients needing a stent.

This trial tests if a special rotating device alone works as well as a more complex approach for treating heavily calcified blockages in the heart arteries. It uses a CT scan to find the right patients.

This trial compares two techniques (orbital atherectomy and intravascular lithotripsy) to break up tough calcium deposits in the heart's arteries that can block blood flow. If you have a calcified nodule and are having a non-emergency procedure to open a blocked artery, this study may help guide which method works best.

This study looks at how safe and effective a treatment is for heart artery blockages that are heavily hardened by calcium. It enrolls people who need a procedure to open the artery (with or without a stent) and whose blockage matches specific imaging or access problems.

This trial is testing a new step-by-step approach (algorithm) to treat hardened, calcified blockages in heart arteries during a stent procedure. The goal is to see if this standardized method helps improve outcomes for patients with these tough-to-treat blockages.
