Heart Disease Expert, Dr. Anton Lishmanov, Joins Ashchi Heart & Vascular Center

Heart Disease Expert with Innovative and Cutting Edge Training on Valve Disease, Coronary Artery and Peripheral Vascular Disease

Ashchi Heart & Vascular Center is pleased to announce the joining of Anton Lishmanov, MD, PhD, an endovascular and structural heart disease cardiologist. As a structural heart cardiologist, he specializes in the evaluation, detection and treatment of heart valve disease — heart murmurs, congenitally malformed valves, “blocked” or stenosed valves; “leaky” or insufficient/regurgitant valves as well as failed or malfunctioning prosthetic heart valves. He also specializes in repairing defects or “holes” in the heart such as atrial septal defect (ASD), patent foramen ovale (PFO) or patent ductus arteriosus (PDA). These defects or abnormal valves can be congenital or caused by disease such as “wear and tear.”

We are very fortunate to have Dr. Lishmanov join our team. He is by far one of the best-trained structural heart disease experts in Northeast Florida having performed a large volume of complex to simple coronary procedures in some of the finest teachings centers in the USA.

Dr. Lishmanov’s training includes an internal medicine residency at the University of Missouri followed by an advanced fellowship in cardiology at the University of North Carolina at Chapel Hill, a Cardiac Critical Care Fellowship at Albert Einstein College of Medicine-Montefiore Medical Center and an Advanced Interventional Cardiovascular Fellowship with endovascular and structural heart experience at the prestigious University of Texas Health Science Center at Houston.

He is board certified in internal medicine, cardiovascular disease, cardiac critical care medicine and board eligible in interventional cardiology and endovascular medicine. He is fluent in English and Russian.

What is Structural Heart Disease?

Structural heart disease most often refers to cardiac defects which are congenital in nature (birth defects), but may also include abnormalities of the valves and vessels of the heart wall that develop with wear and tear on the heart, or through other disease processes. The three most common congenital heart diseases are: bicuspid aortic valve (BAV), atrial septal defect (ASD), patent foramen ovale (PFO), and coarctation or narrowing of the thoracic aorta.

BAV is the most common cause of heart disease that presents at birth and affects approximately 1.3% of adults. It leads to faster than normal wear and tear of the aortic valve and is associated with aneurysms of the aorta. It is also may affect up to 50% of the immediate relatives.

An ASD is a hole in the wall (septum), which separates the top two chambers of the heart. A PFO is similar to an ASD; it is a flap-like hole in the wall that separates the upper two chambers of the heart. Coarctation of the aorta is a narrowing of the largest vessel in the body, in the upper chest that carries the blood from the heart, to every other part of the body to supply oxygen and other nutrients.

Non-congenital disease entities such as “leaky valves,” insufficient/regurgitant native and prosthetic valves or blocked native and prosthetic valves are more common and are still part of structural heart disease specialist work. These disease entities cause many different murmurs or sounds that are detected by listening through the stethoscope or via other imaging modalities such as echocardiograms, transesophageal echocardiogram (TEE), or by MRI or CT scan of the heart.

What are Symptoms of Structural Heart Disease?

Atrial septal defect (ASD)

In ASDs

  • Heart palpitations
  • Exercise intolerance
  • Stroke
  • Low oxygen levels in rare patients.
  • Pulmonary Hypertension

 

 

Patent Foramen Ovale (PFO)

 

In PFOs

  • Transient Ischemic Attack (TIA or mini-stroke)
  • Migraine headaches
  • Low oxygen levels in rare patients.
  • “Bends” in divers

 

 

Coarctation of the aorta

In Coarctation/Narrowing of the Aorta

  • High blood pressure in the arms and head w/ low or normal blood pressure in the legs
  • Stroke
  • Premature coronary artery disease (CAD)
  • Leg cramping w/ exertion
  • Kidney dysfunction
  • Brain aneurysms

 

Valvular Conditions Treated

Aortic Valve Stenosis or Aortic Stenosis

The aortic valve controls blood flow from the heart to the rest of the body. Aortic stenosis (AS) occurs when the aortic valve does not open properly. This forces your heart to work harder to pump blood throughout your body. Over time, the heart muscle weakens. This affects your overall health and keeps you from participating in normal daily activities. Left untreated, severe AS is a very serious, life-threatening condition leading to heart failure and increased risk for sudden cardiac death. Severe symptomatic aortic stenosis has worse survival than metastatic cancer. It is often not preventable, causing the narrowing of the aortic valve, and may be related to the following:

  • Age
  • A buildup of mineral (calcium) deposits that narrows the aortic valve (stenosis)
  • Radiation therapy
  • A history of a bacterial infection of the heart or rheumatic fever
  • Congenital (bicuspid valve)
  • Increased fat in the blood vessels (high cholesterol)

 

Signs and symptoms of severe AS can include:

  • Chest pain or tightness
  • Feeling faint or fainting with activity
  • Dizziness
  • Fatigue
  • Shortness of breath
  • Irregular heart beat (palpitations)
  • Unusual sound heard during a heartbeat (murmur)
  • Slowing down and which often attributed to “being old”

 

Mitral Valve Disease

Repair of an aortic stenosis (AS)

This disease develops when the mitral valve, which is located between the left chambers of your heart – the left atrium and ventricle — doesn’t work correctly.

Types of mitral valve conditions include:

  • Mitral Valve Stenosis
    Mitral stenosis is a narrowing of the mitral valve opening. Mitral stenosis restricts blood flow from the left atrium to the left ventricle. Mitral stenosis is caused when blood flow through the narrow valve opening is reduced. As a result, the volume and pressure from blood remaining in the left atrium increases, which then causes the left atrium to enlarge. Mitral stenosis usually results from rheumatic fever, a childhood illness that sometimes occurs as a result of untreated strep throat or rheumatic fever. Symptoms are similar to those of AS.
  • Mitral Valve Regurgitation – “Leaky” or Insufficient
    This condition occurs when the flaps or leaflets of the mitral valve don’t close tightly, causing blood to leak backward into your heart. The most common cause of the problem is mitral valve prolapse, in which the leaflets bulge back into the left atrium as your heart contracts. If left untreated, it could damage the heart muscle causing such conditions as heart failure and or enlargement of the left ventricle (chamber). It can also lead long term to irreversible damage to lungs and pulmonary hypertension (high pressures in the lungs) among other symptoms.

Treatment

For patients with congenital heart defects or heart valve disease, diagnostic and interventional procedures can be performed in either our state-of-the-art, outpatient catheterization lab or the local hospitals using minimally invasive techniques. Procedures include diagnosing and repairing mitral valves, replacing aortic valves, sealing leaky valves and more. “Holes” or defects in the heart or vessels can be sealed by special closure devices. Dr. Lishmanov has performed these procedures in one of the most prestigious training programs in the United States and is eager to help advance cardiac care in Northeast Florida to a new level.
