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
Pulmonary vein ablation, also called pulmonary vein antrum isolation or PVAI, is a treatment for atrial fibrillation (afib). Afib is the most common irregular heart rhythm. It starts in the atria, or the upper chambers of the heart. When afib occurs, many different electrical impulses rapidly fire at once. These impulses cause a very fast, … 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

We usually don’t notice the beating of our hearts unless something out of the ordinary occurs. Most people occasionally feel the sensation of extra heartbeats. While certain issues with your heart’s electrical system are concerning and serious, sometimes extra heartbeats aren’t clinically significant. Usually this occurs due to benign rhythm disturbances in the heart’s lower … Read More
Many medical dramas on TV or in the movies feature defibrillation or “shock” paddles when someone is in the midst of a cardiac arrest. Similarly, an implantable cardioverter defibrillator, or ICD, is an electronic device that constantly monitors your heart rhythm. It delivers energy to the heart muscle once it detects a very fast, abnormal … 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
A heart block is a problem in the heart’s electrical system. Find out the different types and what types of issues they can cause.
Did you know that arrhythmias, or abnormally rapid heartbeats, can be present at birth? Watch as our expert explains.
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
