      Aortic Stenosis

Aortic Stenosis is the abnormal narrowing of the aortic valve from the ventricle into the aorta. When the aortic valve gets damaged, it restricts blood flow from the ventricle into the aorta making you feel weaker, out of breath and generally unwell. If you have a mild case of Aortic Stenosis, you may not need treatment, but in severe cases, surgery may be required to repair or replace the heart valve.

Family and friends are usually the first people to notice the symptoms of heart valve disease because they notice the day to day weakening and slowness in their loved ones.  Typically, people think the change in habits is just a part of normal ageing, so if you notice it’s getting harder to breathe or you struggle walking to the letterbox or make a cup of coffee please tell your doctor and ask for a check-up.

How do you get Aortic Stenosis?

  • People may be born with an abnormality of the aortic heart valve
  • You have rheumatic heart disease, a condition that scars the aortic heart valve and narrows its opening
  • You have developed a build-up of calcium which stiffens the heart valve and restrict the flow of blood

The population and Aortic Stenosis

Approximately 14% of the Australian population over the age of 75 will experience some form of Aortic Stenosis. The symptoms of an Aortic Stenosis are commonly misunderstood by patients as ‘normal’ signs of ageing, but on a closer examination, up to 37% of people exhibit symptoms that can be mild, moderate or severe. Family and friends will usually notice the first signs as you find it hard to walk to the mailbox or you get out of breath when making a cup of tea.

Symptoms of Aortic Stenosis

  • Shortness of breath
  • Angina
  • Fatigue
  • Syncope (fainting or passing out) or Presyncope (The sensation that you’re going to faint)
  • Rapid or irregular heartbeat
  • Palpitations – an uncomfortable awareness of the heart beating rapidly or irregularly

 Surgical procedures for Aortic Stenosis

  • Heart Valve Replacement
  • Transcatheter Aortic Valve Implantation (TAVI)
  • Balloon Valvuloplasty

Severe Aortic Stenosis can be life-threatening. A referral to the Norwest Heart Valve Team may be required when considering treatment for:

  • Asymptomatic patients (a condition producing or showing no symptoms) with severe heart valve disease.
  • Patients with multiple comorbidities (disorders co-occurring with a primary disease or disorder) where a heart valve intervention may be considered.

How do you get Aortic stenosis?

  • People may be born with an abnormality of the aortic valve in your heart.
  • You have rheumatic heart disease, a condition that scars the aortic heart valve and narrows its opening.
  • You have developed a build-up of calcium which stiffens the aortic valve and restrict the flow of blood.

TAVI (Tranascatheter Aortic Valve Insertion)

Transcatheter aortic valve implantation (TAVI) is a procedure that allows an aortic valve to be implanted using a long narrow tube called a catheter. Usually, the catheter is inserted into a large blood vessel in your groin or through a small incision in your chest.

Percutaneous Coronary Intervention (PCI)

Percutaneous Coronary Intervention (PCI) is sometimes called, an angioplasty with stent. PCI is a non-surgical procedure that uses a catheter to place a stent in the blood vessel of the heart that has been narrowed by plaque build-up.

Adjunctive imaging can also be used to further assist in coronary intervention such as IVUS and OCT.

Diagnostic imaging such as Intravascular Ultrasound (or IVUS) lets cardiologists see inside a coronary artery in real time, yielding information beyond routine imaging methods such as coronary angiography or non-invasive Multislice CT scans.

Intravascular optical coherence tomography (OCT) can add value to angiography as a diagnostic and/or intervention tool for percutaneous coronary intervention (PCI) guidance.

Rotablation

This is a procedure which attempts to “bore out” a narrowing in a coronary artery which might not otherwise respond to stenting.

Intravascular Ultrasound

Intravascular Ultrasound (or IVUS) lets cardiologists see inside a coronary artery in real time, yielding information beyond routine imaging methods such as coronary angiography or non-invasive multislice CT scans.

Patent Foramen Ovale (PFO)

The heart is divided into four chambers. The upper chambers are called the right and left atria. The lower chambers are the right and left ventricles. In fetal circulation, the foramen ovale is an opening that allows blood to bypass the lungs and go directly from the right atria to the left atria. Shortly after birth, the higher pressure in the left atria and the lower pressure in the right atria causes permanent closure of the foramen ovale in the majority of people. A PFO occurs when the opening does not close. This opening can allow blood to pass from the right atria to the left atria. Many times a PFO is not discovered until adulthood.

PFO’s are suspected to be a cause of cryptogenic stroke (a stroke that cannot be linked to a specific cause). Some research suggests there may be a link between PFO’s and migraine headaches.

Atrial Septal Defect (ASD)

An ASD is a hole in the part of the septum that separates the atria—the upper chambers of the heart. This heart defect allows oxygen-rich blood from the left atrium to flow into the right atrium instead of flowing to the left ventricle as it should. Many children who have ASDs have few if any, symptoms.

Ischemic Heart Disease

Ischemic heart disease occurs when there is reduced blood supply to the heart.

Structural Heart Disease (SHD)

People with structural heart disease fall into two categories:

  1. People are born with the disease – i.e. a hole within the chambers of the heart
  2. They acquire  SHD through wear and tear – i.e. a tight or leaky heart valve.
Heart Failure

Heart failure occurs when the heart muscle has become too weak or too stiff to pump blood through the body as effectively as normal.

Arrhythmias

Heart arrhythmia refers to a group of symptoms where the heartbeat is irregular, too slow, or too fast. Arrhythmias are broken down into:

  • Slow heartbeat (bradycardia).
  • Fast heartbeat (tachycardia).
  • Irregular heartbeat (flutter or fibrillation).
  • Early heartbeat (premature contraction).
