Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Area of Science:

  • Cardiovascular Surgery
  • Medical Imaging
  • Minimally Invasive Procedures

Background:

  • Real-time three-dimensional echocardiography (RT3DE) aids atrial septal defect (ASD) closure but has limited resolution for small intracardiac structures.
  • Suboptimal visualization hinders the clinical application of current imaging systems for complex cardiac interventions.

Purpose of the Study:

  • To evaluate the complementary use of videocardioscopy with RT3DE for image-guided ASD closure.
  • To assess the feasibility and effectiveness of combined imaging in a preclinical model.

Main Methods:

  • Atrial septal defects (ASDs) were created and closed in a porcine model (n=5) using RT3DE guidance.
  • A catheter-based patch-delivery system with mini-anchors was employed under combined RT3DE and videocardioscopy.
  • Videocardioscopy utilized an endoscope inserted through a custom port designed for intracardiac visualization in blood.

Main Results:

  • Successful closure of all created ASDs (4-mm to 8-mm) was achieved.
  • The combined RT3DE and videocardioscopy approach provided detailed visualization of intracardiac structures, instruments, and closure devices.
  • High-resolution imaging facilitated clear identification of the patch and mini-anchors during the procedure.

Conclusions:

  • Beating-heart ASD closure is feasible using combined RT3DE and videocardioscopy imaging.
  • Videocardioscopy enhances image resolution, potentially improving the safety and efficacy of image-guided cardiac interventions.
  • This combined imaging strategy offers a promising advancement for minimally invasive ASD repair.
