Modern cardiology has transformed how heart valve conditions are diagnosed and treated. One of the most advanced procedures used to treat severe aortic valve narrowing is Transcatheter Aortic Valve Implantation (TAVI). Before this minimally invasive procedure can be performed, cardiologists must carefully evaluate the patient’s heart structure, overall health, and the severity of valve disease.
At Liv Hospital, specialists follow a structured diagnostic pathway to ensure that each patient receives the safest and most effective treatment plan. For a comprehensive medical explanation of the evaluation process, you can also explore CARDIOLOGY Diagnosis and Tests to understand how physicians determine whether TAVI is the right option.Why Diagnosis Is Critical Before TAVI
TAVI is a highly precise procedure that involves inserting a replacement valve through a catheter rather than performing open-heart surgery. Because the valve must fit perfectly and function immediately after placement, accurate diagnostic measurements are essential.
The evaluation process helps cardiologists:
- confirm that aortic stenosis is the main cause of symptoms
- determine the severity of valve narrowing
- assess the anatomy of the heart and blood vessels
- identify other conditions that may affect the procedure
This detailed planning ensures that the replacement valve can be safely implanted and function effectively.Initial Clinical Examination
The diagnostic journey usually begins with a clinical assessment. During this stage, the cardiologist reviews symptoms such as chest discomfort, fatigue, dizziness, or shortness of breath. These symptoms often appear when the aortic valve becomes significantly narrowed.
A physical examination is also performed, during which the physician listens to the heart using a stethoscope. A characteristic heart murmur—caused by turbulent blood flow through the narrowed valve—can often provide the first indication of aortic stenosis.
Doctors may also examine pulse patterns and blood pressure to identify signs that the heart is struggling to pump blood efficiently.Echocardiography: The Key Diagnostic Tool
One of the most important tests used to evaluate aortic valve disease is the echocardiogram. This imaging method uses ultrasound waves to create moving pictures of the heart.
Echocardiography helps doctors examine:
- the opening size of the aortic valve
- the speed of blood flow through the valve
- the pumping strength of the heart muscle
- the presence of other valve abnormalities
Transthoracic echocardiography (TTE)
This is the most common type of heart ultrasound. A small handheld device is placed on the chest to capture images of the heart from outside the body.Transesophageal echocardiography (TEE)
In some cases, more detailed images are needed. For this test, a thin probe is gently guided into the esophagus to obtain clearer views of the heart valves and surrounding structures.CT Scanning for Precise Valve Measurement
Cardiac CT scanning is a crucial step when preparing for TAVI. This imaging method provides high-resolution three-dimensional images of the heart and major blood vessels.
The CT scan allows cardiologists to:
- measure the aortic valve opening precisely
- evaluate the size and shape of the aortic root
- assess the arteries that will guide the catheter to the heart
Because the replacement valve must match the patient’s anatomy precisely, even small measurement differences can affect the outcome of the procedure.Cardiac Catheterization and Coronary Angiography
Before performing TAVI, doctors also evaluate the coronary arteries to check for blockages. This is done through a procedure called cardiac catheterization.
During this test, a thin catheter is inserted through a blood vessel in the wrist or groin and guided toward the heart. Contrast dye is injected so that doctors can observe blood flow through the coronary arteries using X-ray imaging.
If significant blockages are discovered, they may be treated before or during the valve replacement procedure to ensure optimal blood flow.Additional Health Assessments
Because TAVI candidates are often older adults or individuals with multiple health conditions, physicians may conduct additional tests to assess overall health.
These evaluations may include:
- lung function tests to measure breathing capacity
- physical endurance assessments
- blood tests to evaluate kidney function and other organ systems
These assessments help doctors understand how well a patient might tolerate the procedure and recover afterward.The Role of the Multidisciplinary Heart Team
After completing the necessary diagnostic tests, a multidisciplinary group of specialists—often called the Heart Team—reviews all findings together. This team typically includes cardiologists, cardiac surgeons, imaging specialists, and anesthesiologists.
Together they evaluate the patient’s heart structure, medical history, and overall risk profile to determine the best treatment strategy. In many cases, TAVI offers an effective and less invasive solution for patients who may not be ideal candidates for traditional open-heart surgery.Supporting Long-Term Cardiovascular Health
Accurate diagnosis is only the first step in managing aortic valve disease. Maintaining heart health through regular monitoring, healthy lifestyle habits, and ongoing medical care is equally important.
In addition to clinical treatment, focusing on nutrition, physical activity, and stress management can contribute to better cardiovascular wellbeing.
