Insights

This study establishes reference ranges for atrioventricular plane displacement (AVPD) in healthy Han Chinese adults using cardiac MRI. Age significantly influences AVPD, highlighting its importance in assessing myocardial function.

Area of Science:

  • Cardiovascular imaging
  • Cardiac mechanics
  • Ventricular function assessment

Background:

  • Atrioventricular plane displacement (AVPD) and cardiac valve plane displacement (CVPD) are key to longitudinal ventricular function.
  • These parameters vary with age, but reference values for Han Chinese adults are lacking.

Purpose of the Study:

  • To establish reference ranges for AVPD in healthy Han Chinese adults.
  • Utilize cardiac magnetic resonance (MR) imaging for precise measurements.

Main Methods:

  • Prospective, single-center study involving 200 healthy Han Chinese adults.
  • 3.0 Tesla MR imaging with steady-state free precession (SSFP) sequence.
  • Quantification of left ventricle (LVAVPD) and right ventricle (RVAVPD) using long-axis cine images.

Main Results:

  • Mean LVAVPDavg was 14.0±1.5 mm and RVAVPDavg was 18.7±2.3 mm.
  • No significant sex differences were found, but significant age-related variations were observed.
  • Age, end-diastolic volume (EDV), and end-diastolic volume index (EDVi) were significant determinants of AVPD.

Conclusions:

  • Presents normative LVAVPD and RVAVPD ranges for healthy Han Chinese adults.
  • Demonstrates age-related changes and correlations with EDV, stroke volume (SV), and ejection fraction (EF).
  • Supports the clinical utility of AVPD in myocardial function assessment.

Pulse rhythm01:30

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
Holter Monitor: 24-Hour Monitoring01:23

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...
