TEER in Adult Congenital Heart Disease Patients: Evaluating Clinical Effectiveness and Safety

Atrioventricular Valvular Regurgitation: Understanding Heart Disease in Adults

October 20, 2025 – A notable number of adults living with congenital heart disease are also experiencing atrioventricular valvular regurgitation (AVVR), a condition where blood leaks backward through the heart valves. Recent data from the American Heart Association indicates that roughly 30% of individuals with congenital heart defects develop some form of valvular regurgitation during their lifetime.

What is Atrioventricular Valvular Regurgitation?

Atrioventricular valvular regurgitation involves the mitral or tricuspid valves, situated between the heart’s upper and lower chambers.When these valves don’t close properly, blood flows backward, reducing the heart’s efficiency.This can lead to a range of symptoms, including shortness of breath, fatigue, and swelling in the legs and ankles.

The Link to Congenital Heart Disease

Congenital heart disease, present at birth, often creates structural abnormalities that predispose individuals to AVVR. These abnormalities can strain the valves over time leading to dysfunction. The condition is frequently discovered during routine follow-up appointments with cardiologists specializing in adult congenital heart disease (ACHD).

Diagnosis and Monitoring

Doctors typically diagnose AVVR using echocardiograms, a non-invasive ultrasound of the heart. Regular monitoring is crucial. According to a study published in the *Journal of the American College of Cardiology* in March 2024 , individuals with mild to moderate AVVR may only require periodic check-ups. Though, severe regurgitation demands closer attention and potential intervention.

Understanding Severity

The degree of regurgitation is categorized as mild, moderate, or severe. This classification guides treatment decisions and helps predict long-term outcomes.

Severity	Symptoms	Management
Mild	Often asymptomatic	Routine monitoring with echocardiograms
Moderate	May experience mild fatigue or shortness of breath	More frequent monitoring; potential medication
Severe	Significant shortness of breath, fatigue, swelling	Medication, possible valve repair or replacement

did You Know? Early detection and management of AVVR can significantly improve quality of life and prevent complications.

Treatment options

Treatment for AVVR varies based on severity and individual factors. Options range from medication to manage symptoms to more invasive procedures like valve repair or replacement. Minimally invasive surgical techniques are becoming increasingly common, offering quicker recovery times and reduced scarring.

Pro Tip: Maintaining a heart-healthy lifestyle, including regular exercise and a balanced diet, is essential for managing AVVR and overall cardiovascular health.

Long-Term Outlook and Ongoing Research

Ongoing research is focused on developing new therapies and improving the durability of valve repairs and replacements. Researchers are also investigating the potential of regenerative medicine to repair damaged heart valves. The long-term outlook for individuals with AVVR is improving thanks to advancements in medical technology and care.

What are the key advantages of TEE over TTE in evaluating ACHD patients, specifically regarding anatomical visualization and diagnostic accuracy?

Understanding Transesophageal Echocardiography (TEE) in ACHD

Transesophageal echocardiography (TEE) is a crucial imaging modality for evaluating adult congenital heart disease (ACHD). Unlike transthoracic echocardiography (TTE), which images through the chest wall, TEE provides higher resolution images by inserting a probe into the esophagus, positioning it closer to the heart. This proximity is particularly valuable in ACHD patients, where anatomical complexities and prior surgical repairs often limit TTE’s effectiveness. The improved image quality allows for detailed assessment of cardiac structures, function, and potential complications. Key search terms include: adult congenital heart disease imaging, TEE protocol ACHD, congenital heart defect diagnosis.

Why TEE is Preferred in Complex ACHD Cases

Several factors contribute to TEE’s superiority in specific ACHD scenarios:

* Improved Visualization: TEE excels in visualizing structures obscured by lung tissue or surgical scars, such as the posterior aspects of the heart, the atrial baffle in Fontan circulation, and the pulmonary veins.

* Detection of Thrombi: ACHD patients are at increased risk of thromboembolic events. TEE is highly sensitive in detecting intracardiac thrombi, particularly in the atria and around surgical baffles. ACHD thrombosis risk, TEE thrombus detection.

* Assessment of Shunt Patency: For patients with palliative shunts (Blalock-Taussig shunt, glenn shunt), TEE accurately assesses shunt patency, stenosis, and collateral circulation.

* Evaluation of Valve function: TEE provides detailed assessment of prosthetic valve function,including leaflet motion,regurgitation,and the presence of pannus formation. prosthetic valve assessment TEE, congenital valve disease.

* Detection of Air Leak: In patients post-fontan, TEE can identify air leaks, a potentially life-threatening complication.

clinical applications of TEE in Specific ACHD Lesions

TEE plays a vital role in the management of various ACHD conditions:

* Tetralogy of Fallot (TOF): Assessing pulmonary valve regurgitation, right ventricular size and function, and the presence of residual ventricular septal defects.

* Transposition of the Great Arteries (TGA): Evaluating baffle leaks in the atrial switch operation (Mustard/Senning procedure) and assessing neo-pulmonary valve function.

* Fontan Circulation: Detecting venous obstruction, assessing systemic ventricular function, identifying atrial arrhythmias, and monitoring for protein-losing enteropathy (PLE) through assessment of hepatic venous pressures. Fontan circulation TEE, PLE detection.

* Coarctation of the Aorta: Evaluating the severity of coarctation, assessing collateral circulation, and identifying associated aortic aneurysms or dissections.

* Ebstein’s Anomaly: Assessing tricuspid valve morphology, degree of regurgitation, and right atrial size.

Safety Considerations and Potential Complications of TEE

While generally safe, TEE is not without risks. Careful patient selection and monitoring are essential.

* Esophageal Perforation: A rare but serious complication. Experienced operators and appropriate sedation are crucial.

* Arrhythmias: Esophageal stimulation can induce atrial or ventricular arrhythmias. Continuous ECG monitoring is mandatory.

* Hypoxia: Transient hypoxemia can occur due to esophageal compression of the trachea or mainstem bronchi.

* Aspiration: Patients should be NPO (nothing by mouth) for a specified period before the procedure to minimize aspiration risk.

* Drug Allergies: Sedation medications must be carefully selected considering patient allergies and medical history. TEE complications, TEE safety protocol.

Optimizing TEE Examinations in ACHD: Practical tips

To maximize the clinical utility of TEE in ACHD patients:

1. Pre-Procedure Assessment: Thoroughly review the patient’s medical history,including prior surgeries,medications,and allergies.
2. Appropriate Sedation: Utilize monitored anesthesia care (MAC) with adequate analgesia and amnesia.
3. Multiplane Imaging: Employ multiplane imaging to obtain optimal views of complex anatomical structures.
