Clinical update in cardiac imaging including echocardiography

Area of Science:

• Cardiovascular Imaging
• Cardiac Surgery
• Interventional Cardiology

Background:

• Current guidelines focus on valvular stenosis, particularly aortic stenosis, and its assessment challenges.
• Echocardiography, including 3D and transesophageal modalities, plays a key role in evaluating various cardiac conditions and guiding interventions.
• Tricuspid valve regurgitation is common with mitral disease and requires attention during surgery.

Purpose of the Study:

• To evaluate the role of cardiac magnetic resonance imaging in assessing right ventricular dilation and pulmonary regurgitation post-tetralogy of Fallot repair.
• To summarize recent advancements and guidelines in the assessment and management of valvular heart disease, including aortic, mitral, and tricuspid regurgitation.

Main Methods:

• Cardiac magnetic resonance imaging for volumetric determinations.
• Echocardiography (3D, transesophageal) for valvular assessment and procedural guidance.
• Multislice computed tomography for simultaneous cardiac valve and coronary artery assessment.

Main Results:

• Cardiac MRI may offer accurate assessment for guiding pulmonary valve replacement in tetralogy of Fallot repair.
• 3D echocardiography aids in transcatheter procedures and detailed valve/chamber assessment.
• Evidence supports mitral valve repair for asymptomatic mitral regurgitation with effective regurgitant orifice area >40 mm(2).
• Tricuspid annuloplasty is recommended for annular diameter >35 mm, with repair preferred over replacement.

Conclusions:

• Cardiac MRI is valuable for post-tetralogy of Fallot repair management.
• Comprehensive echocardiographic assessment is crucial for various valvular heart diseases.
• Timely intervention for mitral and tricuspid regurgitation, guided by specific criteria, improves outcomes.
