Procedures Performed

Transcatheter Aortic Valve Replacement (TAVR)

Transcatheter Aortic Valve Replacement (TAVR) refers to a minimally invasive procedure used to replace the aortic valve.

Electrophysiology

Nuclear Cardiology

Stress testing, including nuclear

A noninvasive way to look for blocked arteries by stressing your heart with exercise or medications. Nuclear testing produces images of the heart’s structure and blood flow under stress.

Catheterization & angiography

The “gold standard” in evaluating for blocked arteries. A small,flexible tube helps X-rays to “look for” blocked arteries and can help measure pressures in the heart and blood vessels.

Coronary stenting

Permanent pacemaker implantation

Echocardiograms and stress echocardiograms

Holter and event monitoring

Coronary artery bypass graft surgery (CABG)

Cardiac valve surgery

Tilt Table Test

One syndrome that may cause fainting spells is called neurocardiogenic syncope. In this disorder, an overactivity of one part of the nervous system (sympathetic nervous system, which is responsible for the "fight-flight" response), leads to a rebound lowering of the pulse and blood pressure, with a pooling of blood in the leg veins, leading to dizziness and passing out. A tilt table exam is a provocative test that, in a controlled setting, brings out the typical characteristics of this syndrome in a patient who has neurocardiogenic syncope. During a tilt study, the patient is lays flat on a cushioned table with seat belts. The table is then tilted head upward for a period of time, usually twenty minutes. A patient with neurocardiogenic syncope will manifest the typical symptoms of slow heart rate and lowering of blood pressure in response to this measure.

Surgical Stripping

One way that varicose veins are treated is through an open surgical procedure. In this procedure, a surgeon makes an incision and ties off or removes ("strips") the varicose vein. This is typically done in a hospital under general anesthesia.

Ambulatory Phlebectomy

In this procedure, the doctor makes a small (2 mm) nick in the leg. He then inserts a hook instrument under the skin and grabs the vein, then excises it out of the leg through the incision, removing it permanently. The incision is then closed using strips of tape. Stitches are not required. This procedure is done in the office.

EndoVenous Laser Ablation (EVLA)

In this technique, known as EndoVenous Laser Ablation (EVLA), a small laser catheter is inserted into the vein and laser energy is applied to the inner wall of the vein, causing the vein to close permanently. The EVLA procedure takes about an hour and is done in a doctor's office.

Ultrasound-Guided Chemical Ablation, or Foam Sclerotherapy

Another very successful technique for treating varicose veins involves using a liquid chemical compound known as a "sclerosant". The sclerosant, which is mixed with air and prepared as a foam, is injected into the vein with a small needle. This chemical interacts with the inner lining of the vein wall and causes the vein to spasm and close. The foam property of the chemical causes it to stay in contact with the vein wall, rather than washing away with the venous blood flow. In the ensuing hours, the vein channel clots and permanently closes.

Sclerotherapy

Sclerotherapy involves injection of a liquid chemical substance (sclerosant), into the vein. This causes the vein to spasm and close.
