If you could get a glimpse inside your aortic artery, you would see that it’s much like the inside of a garden hose. It has a thick inner layer with a thinner outer layer as protection. When the artery is healthy, that muscular inner layer is round and wide. This allows easy flow of blood … Read More
While most serious issues related to heart rhythm disturbances occur in the heart’s upper chambers, or atria, sometimes they do occur in the lower chambers, the ventricles, which are the main pumping chambers. This can cause a very rapid heartbeat called ventricular tachycardia. It’s usually caused by scarring from a heart attack or other issues … Read More
Sometimes the pathway in the heart’s electrical system is interrupted, which causes changes in heart rate and rhythm. A slow heartbeat can occur because the sinus node, the natural “battery” of the heart, is slow. Other times electrical conduction between the upper and lower chambers of the heart is disrupted. When this happens, the heart … Read More
Some patients have abdominal aortic aneurysms that dilate the aorta at or above the renal arteries. These are the arteries that branch out to the kidneys. Vascular surgeons use fenestrated stent grafts to open the renal arteries. These grafts have openings cut at just the right spot so they don’t block blood flow through the … Read More

Treating aneurysms throughout the body usually requires open surgery, but now we’re able to use a minimally invasive procedure to repair abdominal aortic aneurysms. These are aneurysms that occur in the part of the aorta that carries blood from the heart into the lower extremities. In traditional open surgery, surgeons go in and repair the aneurysm, or … Read More
Your heart’s electrical system is the power source that keeps your heart beating regularly. When something goes wrong with the heart’s “wiring,” you can develop an arrhythmia, which is an irregular or abnormal heartbeat. In this white board session, Walid Saliba, MD, Director of Cleveland Clinic’s Electrophysiology Lab, explains how a procedure called a catheter … Read More
Nearly 100 percent of arrhythmias, or irregular heartbeats, that occur take place in the atria, or the upper chambers of the heart. The most common ones that we hear about are atrial fibrillation and its cousin, atrial flutter. When this occurs, the heart’s electrical system misfires, causing the rapid firing of too many different impulses … Read More
Newer surgical techniques are making lobectomies less invasive. Watch this video to learn more.
Lung cancer is the leading cause of cancer-related death in the United States, which means that many people have been touched by the disease—either as a patient or as a friend or loved one of someone with a lung cancer diagnosis. While we often hear talk of lung disease, it’s important to understand the physiology … Read More
It’s the “good fat.” High-density lipoprotein (HDL) cholesterol can actually protect you against heart disease. And you can boost your levels by adopting a healthy lifestyle: eat right, exercise regularly and don’t smoke. In this whiteboard session, cardiologist Michael Rocco, MD, shares how HDL cholesterol works to your heart’s benefit.
