Cardiac/Peripheral Vascular Catheterizations

What is a Cardiac Catheterization?

Cardiac Catheterization | Hunterdon Cardiovascular Associates | New Jersey

A cardiac catheterization is a procedure in which a catheter, or a long hollow tube, is inserted through an artery towards the heart. Dye is then injected under X-ray in order to visualize the arteries of the heart muscle. If necessary, a stent may be inserted in order to open a blocked artery.

Traditionally this procedure is performed through an artery in the groin. However, the interventional cardiologists of Hunterdon Cardiovascular Associates, under the lead of William Schafranek, MD, Medical Director of the Cardiac Catheterization laboratory at Hunterdon Medical Center, are trained at completing this procedure through an artery in the wrist. This is known as the transradial approach and is a technique that enhances patient comfort as well as mobility after the procedure. In addition, the transradial approach provides patients with a significantly shorter hospital stay. At the same time, this approach reduces the risk of bleeding complications. With close to 85% of our cardiac catheterizations done transradially and far exceeding the national average, our interventional cardiologists are among the most experienced in the state at this technique.

Our interventional cardiologists also have available and are proficient at using some of the most cutting-edge technology currently available for the interventional treatment of coronary artery disease, including bioabsorbable stents, calcium cutting tools, and the Impella percutaneous left ventricular assist device.

Peripheral Catheterization

The interventional cardiologists of HCA can also provide similar catheterization services that can help open up blocked arteries in the peripheral vasculature, including the extremities, the gut, and the kidneys, as well as for the treatment of deep venous thrombosis of the extremities. We combine this with a guideline based approach for noninvasive screening in partnership with our accredited vascular imaging department, we treat patients with both acute and chronic symptoms of peripheral arterial disease.

Am I a Candidate for a Cardiac Catheterization?

Your doctor may request a cardiac catheterization for you to explore the potential reason for:

  • Dramatically abnormal stress test results
  • Heart failure that may be associated with coronary artery disease
  • Angina that disrupts daily living and is difficult to control with medication
  • Symptoms of heart valve disease, such as shortness of breath
  • Unidentifiable recurrent chest pain

What to Expect When Getting a Cardiac or Peripheral Vascular Catheterization

Preparing for a cardiac catheterization

Our doctors may provide you with detailed instructions regarding preparation for your cardiac catheterization procedure. Generally, patients should:

  • Avoid blood-thinning medications in the days before cardiac catheterization (but not typically aspirin or other anti-platelet medications). A physician will discuss this with you before your procedure.
  • Discuss exact dosages of medications currently taken. Patients may be asked to bring original bottles of all medications and supplements with them to their test.
  • Avoid eating and drinking in the 6 hours before cardiac catheterization. Diabetic patients may need to discuss medication and insulin instructions with their doctor.
  • Implement relaxation techniques to calm nerves before and during testing. Medication may be given before cardiac catheterization to help reduce anxiety.

The Cardiac Catheterization Procedure

Cardiac Catheterization | Hunterdon Cardiovascular Associates | New JerseyCardiac catheterization takes place in an operating room that is equipped with special imaging devices. This may be referred to as a cardiac cath lab.

Typically, patients are sedated before their procedure begins. Sedation is not general anesthesia so patients are awake but calm and comfortable. Your doctor will discuss your anesthesia with you prior to your procedure based on the particulars of your case.

  • Before catheterization, we will insert an IV line into the arm. As arranged, additional medication may be administered through this IV during the procedure.
  • Our staff will place electrodes on the chest to monitor your heartbeat.
  • The site where the catheter will be inserted may be shaved. An injection of numbing medication will be administered at this site.
  • After the tissue has become numb, a small nick is made in the skin. A plastic sheath is inserted into this tiny incision, and the catheter is passed through.

Once the catheter has been inserted, a number of different processes may take place. Cardiac catheterization may facilitate:

  • Coronary angiogram to check for arterial blockages
  • Right heart catheterization to assess blood flow from the right side of the heart
  • Balloon angioplasty with or without stenting to open a blocked artery
  • Heart ablation to correct an irregular heartbeat

Patient Story About why A Cardiac Catheterization Is Important

The Patient is a 91 year old female admitted to the hospital with shortness of breath and chest pain. She denied any significant past cardiac history. A cardiac catheterization performed showed a severe blockage in the left main coronary artery and another blockage in the left circumflex.

Blockages in the left main coronary artery are felt to be best treated with open heart surgery and she was referred to a surgeon for an evaluation. She was evaluated by cardiac surgery and because of her age and other non-cardiac medical history, she was felt to be a poor candidate for cardiac bypass surgery. She continued to have chest pain with minimal activity and after discussion with her family, medical team, and Dr. Schafranek a decision was made to proceed with a high risk procedure to place a stent in the left main coronary artery.

She underwent this procedure without any complications and was discharged home the following day. She had been doing very well since then.

 

How long is the recovery from Cardiac Catheterization?

Initial recovery takes place in a recovery area where our staff will monitor your vital signs while the anesthesia wears off. At this time, the plastic sheath that secured the catheter will be removed. After approximately one hour, once anesthesia has worn off, the patient is released to an outpatient room or hospital room if they will have an overnight stay. It may be necessary to lie flat on the back for several hours after the procedure. Patients can resume eating and drinking shortly after the test and some patients return home on the day of their procedure.

Cardiac Catheterization Results

The results of cardiac catheterization are discussed between doctor and patient after the procedure has been completed. This will give the patient enough time to recover from anesthesia and the physical toll of the test or procedure they have had done.
