Cardiac Surgery Frequently Asked Questions

How common is heart valve disease?

If you are facing heart valve replacement surgery, you are not alone. Each year, more than 700,000 patients globally undergo some type of heart surgery. In fact, you may recognize some of their faces. Barbara Walters, Barbara Bush, Arnold Schwarzenegger, Robin Williams, and Elizabeth Taylor have all had heart valve surgery.

What does a heart valve do?

Your heart pumps blood continually to deliver oxygen to every part of your body. The heart is a powerful muscle that keeps the blood moving by pumping it to the lungs, where it picks up oxygen and delivers it to the rest of the body. When the blood returns to the heart, it is pumped back to the lungs to pick up more oxygen.

For this process to work efficiently, the blood must move freely and in only one direction. The heart’s valves open so blood can move forward, and then close to keep it from moving backward.

This process is repeated 5 or 6 billion times during the average lifetime.

How many valves does the heart have?

The heart has 4 valves. The mitral and tricuspid valves control blood flow between the upper and lower chambers of the heart.

On its way out of the heart to carry oxygen to the rest of the body, blood passes through the pulmonary and aortic valves.

What is heart valve disease?

Several things can go wrong with heart valves.

  • They can leak – when a work out valve fails to close properly or leaks, it’s called prolapsed. Blood flows backward (regurgitates) and the heart must work harder to pump the same amount of blood.
  • They can become narrow due to calcium build-up – this narrowing is called stenosis. It keeps the valve from opening completely and reduces the amount of blood that can flow through it.
  • They can become damaged from an infection – bacteria that causes rheumatic fever can damage the heart, especially its valves. Heart valves can also be damaged or deformed by an infection called bacterial endocarditis.
  • They may be defective due to congenital reasons or wear out with age.

What are the symptoms of valve disease?

A worn out or damaged heart valve can cause some or all of these symptoms:

  • Shortness of breath
  • Feeling tired (fatigue) during exertion
  • A cough, especially at night or when lying down
  • An irregular or abnormally fast heart beat (palpitations)
  • Swollen feet or ankles
  • Pain or tightness in the chest
  • Dizziness

Even a relatively insignificant leak in a valve can cause severe symptoms.

What kinds of tests do doctors use to diagnose heart valve disease?

After discussing your symptoms and listening to your heart to check for a murmur, the doctor may use a number of different tests to “see” how it is working before diagnosing heart valve disease as the cause of your symptoms.

  • A chest x-ray can determine the size of your heart.
  • An electrocardiogram (also called an ECG or EKG) can detect a problem with your heart’s rhythm and some problems with how the blood flows.
  • An ultrasound test called an echocardiogram makes it possible to watch each heart valve, checking on its structure and thickness, as it opens and closes. Your doctor may order a special type of this test, called a transesophageal echocardiogram.
  • A special type of x-ray called a radionuclide scan uses a “tracer” chemical to produce images of a specific organ, such as the heart.
  • The dye that is injected into the bloodstream during a cardiac catheterization allows the doctor to track the movement of blood and detect other heart problems that could be causing your symptoms.
  • Magnetic resonance imaging (MRI) can produce detailed pictures of your heart and arteries and how they function.

What are my surgical options?

During typical open chest surgery to repair or replace a heart valve, the surgeon makes one large main incision in the middle of the chest and breastbone to access the heart. A heart-lung machine takes over the job of circulating blood throughout the body during the procedure, because the heart must be still and quiet while the surgeon operates. Many surgeons are now able to offer their patients minimal incision valve surgery as an effective alternative to open chest surgery.

How is minimal incision valve surgery performed?

Minimal incision valve surgery does not require a large incision or cutting through the entire breastbone. The surgeon gains access to the heart through one of three smaller, less visible incisions (sometimes called “ports”) that are made between the ribs or a smaller breastbone incision in the groin. The diseased valve can be repaired or replaced through one or more of the ports between the ribs, with the surgeon looking at the heart directly or through a small, tube-shaped camera.

What are the benefits of minimal incision valve surgery vs. open chest surgery?

Many studies have demonstrated that minimal incision valve surgery offers patients a number of advantages, including:

  • Less pain
  • Lower risk of complications
  • Faster recovery and return to normal activity
  • A smaller, less visible scar

How long does it take to recover from minimal incision valve surgery?

Patients who have minimal incision valve surgery typically:

  • Spend less time in the intensive care unit after surgery
  • Return home sooner
  • Return to work or normal activities within 4-8 weeks.
  • Are back at work and resuming normal activities by the eighth week (71%).
  • Refer to page 20 of your Educational Guide.

What will I need to do to prepare for surgery?

You will undergo medical tests and different imaging exams to determine:

  • Your overall health
  • Allergies
  • Anatomy
  • Best surgical approach

What happens on the day of surgery?

You will be asked to sign a consent to surgery form.

  • You will be given a specific time to check in to the pre-operating room by your surgeon.
  • You may be asked to follow certain dietary guidelines.
  • Your body may need to be shaved.
  • You will be provided anesthesia as determined by your surgeon.

How long does surgery last?

Usually half a day, which includes prep time, actual surgery time of 2 to 4 hours, and prep time for transfer to the Cardiopulmonary Unit (CPU).

What can I expect after surgery?

  • Pain management
  • Rest
  • Instructions on when to shower/bathe (usually 10 days to two weeks)
  • Dietary guidelines
  • Back-to-activity instructions
  • Follow-up care as determined by your physician

How much pain will I have when I wake up?

The answer depends on many factors, including the approach chosen. However, studies on minimal incision valve surgery suggest a reduced pain level when compared to open chest surgery. Ask your surgeon what you and your family should expect for the type of procedure you will receive.

Will I have a scar?

If you have heart valve replacement surgery, you should expect some scarring. With open chest surgery, you will have a sizeable scar in the middle of the upper chest (6-12 cm). The smaller incisions associated with minimal incision valve surgery (2-6 cm) mean smaller scars, and their locations also make them less noticeable.

How long will I stay in the hospital?

If you have undergone a standard sternotomy procedure, you will remain in the hospital for approximately 5 to 7 days after surgery. If you have undergone a minimally invasive or port access procedure, you will remain in the hospital for approximately 3 days after surgery.

How do I care for myself at home after surgery?

Refer to page 9 of your Educational Guide.

When am I allowed to remove my bandages?

The Steri-strips over the chest tube sites need to remain in place for approximately 2 weeks after surgery. The wounds can then be open to air unless there is drainage, in which case the wound should be covered with a dressing.

How long will I need to rest before returning to work?

Minimal incision valve surgery has been associated with a faster recovery and return to normal activity when compared to open chest surgery. Recovery will depend on several different factors, but clinical studies indicate that approximately 50% of patients will return to work and full activity within 4 weeks.

What are the activities that I can perform when I return home?

All patients are encouraged to resume normal activities at their own pace. Many patients report a return to normal activities with a few weeks.

When can I shower?

You may resume regular bathing habits after the removal of your chest tubes and external pacemaker wires. See page 19 of your Educational Guide.

When can I drive?

If you have undergone a standard sternotomy and are no longer taking pain medication, you may resume driving six weeks after surgery. If you have undergone a minimally invasive procedure or port access procedure, you may resume driving after you are no longer taking any pain medication.

When can I fly?

For shorter trips less than 2 hours in duration, you must wait at least 2 months after surgery before you can fly, if there are no complications. For longer trips more than 2 hours in duration, you must wait at least 3 months before you can fly, if there are no complications.

Why am I constipated?

Constipation after surgery is most commonly due to pain medication. It is very important to take your stool softeners, walk, and eat your vegetables, especially when taking pain medication for longer durations of time. Refer to page 36 of your Educational Guide.
