Real-time 3-dimensional echocardiography (RT3DE) effectively visualizes the coronary sinus (CS) in patients, agreeing with multislice cardiac tomography (MSCT) findings, especially in heart failure cases.

Area of Science:

  • Cardiovascular Imaging
  • Echocardiography
  • Cardiac Tomography

Background:

  • Real-time 3-dimensional echocardiography (RT3DE) is a novel technique for visualizing the coronary sinus (CS).
  • Comparison with multislice cardiac tomography (MSCT) is essential for validation.

Purpose of the Study:

  • To evaluate the efficacy of RT3DE in visualizing and quantitatively assessing the coronary sinus (CS).
  • To compare RT3DE findings with MSCT in patients with and without heart failure.

Main Methods:

  • 37 patients underwent MSCT followed by RT3DE.
  • Patients were divided into two groups: normal left ventricular function (Group A) and heart failure (Group B).
  • Coronary sinus diameter and variations were measured and compared between the two imaging modalities.

Main Results:

  • The CS was visualized in 91% (Group A) and 93% (Group B) of patients using RT3DE.
  • CS diameter was significantly larger in patients with heart failure.
  • RT3DE measurements showed good agreement with MSCT, particularly for proximal segments.

Conclusions:

  • RT3DE is a viable method for visualizing and assessing the coronary sinus.
  • The technique is easily learned and provides results comparable to MSCT.
  • RT3DE shows particular utility in patients with heart failure.
