Insights
Echocardiography, including transthoracic and transesophageal approaches, is crucial for monitoring adults after atrial baffle procedures for transposition of the great arteries. This noninvasive method effectively detects late complications, ensuring optimal patient management.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Medical Imaging
Background:
- Atrial baffle procedures (Mustard, Senning) significantly improved outcomes for transposition of the great arteries.
- Late complications, including obstruction and dysfunction, can arise years after surgery, even in asymptomatic patients.
Purpose of the Study:
- To evaluate the role of echocardiography in the long-term follow-up of adult patients who underwent atrial baffle procedures.
- To highlight echocardiography's effectiveness in detecting and assessing late postoperative complications.
Main Methods:
- Transthoracic 2D and Doppler echocardiography for routine assessment.
- Transesophageal echocardiography (TEE) for detailed evaluation, especially with limited transthoracic windows.
- Comparison with angiography and MRI.
Main Results:
- Echocardiography provides a comprehensive assessment of hemodynamic abnormalities and atrial baffle function.
- TEE offers superior detail for baffle morphology and function compared to other imaging modalities.
- TEE is valuable for guiding and monitoring interventional procedures.
Conclusions:
- 2D and Doppler echocardiography (transthoracic/transesophageal) are the most important diagnostic methods for routine follow-up after atrial baffle procedures.
- These techniques are essential for investigating postoperative anatomy and identifying late complications in adults.
- Echocardiography ensures accurate and effective long-term surveillance for this patient population.
Abstract:
Introduction of the atrial baffle procedure (Mustard, Senning) more than 30 years ago has dramatically improved the prognosis of patients with transposition of the great arteries. However, a range of late complications can occur even in clinically asymptomatic patients including: superior and inferior limb obstruction, pulmonary venous obstruction, residual baffle-leakage, left ventricular outflow tract obstruction, tricuspid valve regurgitation, right ventricular dysfunction and postoperative dysrhythmia. As an increasing number of patients has reached adulthood an accurate noninvasive technique is needed for routine follow-up studies. In most patients transthoracic two-dimensional (2D) and Doppler echocardiography allows a complete investigation of postoperative hemodynamic abnormalities -- in particular assessment of atrial baffle function. In adult patients with restricted echo-windows transoesophageal echocardiography may provide a more detailed assessment of atrial baffle morphology and function; TEE seems to be superior compared to angiography and magnetic resonance imaging. Furthermore TEE is a reliable guiding and monitoring technique during interventional cardiac catheterization procedures such as balloon dilatation or stent implantation and allows further surveillance. Even if compared to other noninvasive diagnostic procedures, 2D and Doppler echocardiography (transthoracic/transoesophageal) are still the most important and accurate diagnostic methods for routine investigation of the postoperative anatomy and potential late complications in patients who underwent an atrial baffle procedure.
