Some issues Dr. John Joseph Mahmarian, FACC, MD can help you with:

Angiogram (Angiography)

Angiography is the use of x-rays to examine blood vessels, especially in order to identify any blocked or misshapen vessels that may cause problems. The test itself is called an angiogram. Some of the disorders that angiograms can be used to diagnose include:

  • Blockages and narrowing
  • Weakened walls and bulging, called an aneurysm
  • Malformations and misshapen blood vessels
  • Kidney artery conditions
  • Aorta artery conditions
  • Vein problems, including deep vein thrombosis (DVT) and blood clots or embolisms

During an angiogram, the doctor inserts a very thin, flexible tube called a catheter into a blood vessel through an opening in the groin or arm. The catheter is threaded through the body to the site of the suspected problem, where a small amount of dye is injected into the bloodstream and x-rays are taken. The dye makes the surrounding blood vessels visible via x-ray.

If necessary, certain procedures can be performed after an angiogram while the catheter is in place. Angioplasty is the use of a catheter to widen narrowed or blocked arteries. Stents are like tiny coiled springs that hold blood vessels open, and they can be placed during a catheterization. Damaged heart valves can also be repaired or replaced.

A typical angiogram takes about an hour to perform, but it may be longer if the catheterization is used to perform procedures on the blood vessels. It may be uncomfortable at times but is usually not painful. Afterwards, patients may be monitored for up to six hours to make sure any bleeding from the insertion site has stopped. They are given fluids to help flush the dye from their body. For a day or two after an angiogram it is important for patients to drink plenty of fluids and keep strenuous activity to a minimum.

Angioplasty

Angioplasty is a common, minimally invasive procedure performed to restore blood flow in arteries and veins that have become narrowed or blocked. Age or illness can cause plaque to build up at certain spots within the veins and arteries, and if enough collects, it can restrict the flow of blood. Angioplasty uses a tiny balloon at the end of a small, flexible tube to inflate within the narrowed section and open it up again.

Angioplasty may be performed in several different areas of the body and for a variety of reasons, most often:

  • Peripheral arterial disease, which reduces blood flow in the arms or legs
  • Atherosclerosis, or general hardening of the arteries
  • Carotid artery stenosis, or narrowing of the arteries in the neck that supply the brain
  • Coronary artery disease, or narrowing of the arteries near the heart
  • Renal vascular hypertension, or narrowing of the arteries in the kidney, leading to increased blood pressure

During angioplasty, a patient is given a sedative while lying on a table under an x-ray machine. A catheter (a thin, flexible, and hollow tube) is inserted into the patient's skin in the arm or groin and guided into the blocked artery. Dye is injected via the catheter, and x-rays are used to position the tip of the catheter exactly at the blockage. The tiny balloon is guided through the catheter and inflated with saline. It pushes the plaque out of the way, squishing it against the walls of the artery. The balloon may be inflated and deflated several times to let blood pass by. A stent, a tiny tube of metal mesh like a spring, may be inserted to help keep the artery open. Then the x-ray is used again to check that blood is flowing properly, the catheter is removed, and the tiny incision is bandaged.

There are no nerves within veins and arteries, so an angioplasty is generally not painful. However, there may be some discomfort at the site of the incision and when the balloon is inflated. Overall, angioplasty is a very effective and low-risk procedure, useful for helping patients avoid more difficult bypass surgery.

Heart Problems

The heart is one of the most important organs in the body. This smooth muscle expands and contracts rhythmically an entire lifetime, pumping blood to the lungs and then to every other cell in the body. When heart problems occur, it becomes difficult for the body to get the nutrients and oxygen it needs via the blood. So while there are a variety of illnesses and disorders that affect the heart, most of them cause weakness, exhaustion and shortness of breath. The most common heart conditions include heart disease, angina, arrhythmia, and valve disorders.

Heart disease is the leading cause of death in the United States for both men and women. This includes coronary artery disease, heart attacks, congestive heart failure, and congenital heart disease. Some conditions, such as genetics, cannot be controlled. But there are many other things one can do to lower their risk for heart disease. Controlling high blood pressure and cholesterol levels, reducing or stopping smoking, exercising more and losing weight if needed, and eating a diet low in sodium can all protect the heart.

Angina is a squeezing type of chest pain that happens when the muscles around the heart don't get enough oxygen. It can be regular or infrequent. Usually, angina is caused by coronary heart disease. However, not all chest pain is angina. Chest pain can also be caused by a lung infection or panic attack, for example, so it is important to have any sudden pain checked.

Arrhythmia is the word for when the heart beats too fast, too slow, or irregularly with skipped beats. It can feel frightening, and depending on the type it can be dangerous, but in most cases arrhythmia is not serious and can be treated. It is very common, especially in older adults.

Heart valve problems can happen in any one of the the heart's four valves that keep blood flowing where it needs to go. Babies can be born with problems in their heart valves, or valves can be damaged by infections. The valves can stiffen and become less mobile, or they can stop closing properly and 'leak' when the heart beats. Valve problems can usually be repaired surgically.
