Area of Science:

  • Cardiology
  • Medical Imaging
  • Echocardiography

Background:

  • The left ventricular apical thin point (LVATP) is a specific anatomical feature.
  • Understanding its dynamic behavior during the cardiac cycle is crucial for cardiac function assessment.

Purpose of the Study:

  • To assess the utility of two-dimensional echocardiography in visualizing the LVATP.
  • To quantify changes in LVATP dimensions throughout the cardiac cycle.

Main Methods:

  • Transthoracic echocardiography utilized in 32 healthy adults.
  • LVATP observed in the apical three-chamber view.
  • Measurements of LVATP width and thickness at end-diastole and end-systole.

Main Results:

  • Two-dimensional echocardiography clearly depicted the LVATP.
  • Significant reduction in LVATP width from end-diastole (3.3 mm) to end-systole (0.9 mm) (P < 0.001).
  • Insignificant change in LVATP thickness between end-diastole (1.7 mm) and end-systole (1.8 mm) (P > 0.05).

Conclusions:

  • Two-dimensional echocardiography is a valuable tool for visualizing the LVATP.
  • LVATP exhibits significant dynamic width changes during the cardiac cycle.
  • LVATP thickness remains relatively constant throughout the cardiac cycle.
