Interventional Cardiology

Interventional cardiology is the treatment of structural heart disease through procedures using a catheter that is placed inside the heart or blood vessel. These minimally invasive procedures can diagnose and repair many heart conditions and eliminate the need for open heart surgery.

Interventional procedures performed by Dr. Johnny Dy include:

Cardiac Catheterization

Cardiac catheterization is a procedure in which the cardiologist advances a thin flexible tube through an artery into the heart. An imaging technique records pictures of the heart while it beats. Cardiac catheterization can help cardiologists diagnose heart defects, heart disease, heart enlargement, blood clots, coronary artery blockage, valve problems, or aneurysm. Learn more about cardiac catheterization in our patient education library.

Coronary Angioplasty

Coronary angioplasty, also called percutaneous coronary intervention, is a procedure used to open blocked heart arteries. A tiny balloon is inserted in the artery and inflated to open the passageway. A stent is often used to prop the artery open and help ensure the blockage does not reoccur.

Pacemaker Insertion

A pacemaker is a common treatment for heart arrhythmia, an irregular heart rhythm that results when the heart beats too fast, too slow, or unevenly. A pacemaker is a small device that is surgically implanted under the skin near the heart to help maintain a regular heartbeat.
