Insights

The Vieussens valve (VV) is a common heart structure. While less detectable via cardiac MSCT than in autopsies, large VVs can be visualized, aiding in catheterization procedures.

Area of Science:

  • Cardiovascular Anatomy
  • Medical Imaging

Background:

  • The Vieussens valve (VV) is an anatomical structure within the human heart.
  • Its precise morphology and visibility in imaging studies require further investigation.

Purpose of the Study:

  • To describe the morphology of the Vieussens valve.
  • To determine if the Vieussens valve is visible using contrast-enhanced electrocardiogram-gated multislice computed tomography (MSCT).

Main Methods:

  • Examination of 145 human autopsied hearts.
  • Analysis of 114 cardiac MSCT scans.

Main Results:

  • The Vieussens valve was detected in both autopsied hearts (62.1%) and MSCT scans (18.4%).
  • The VV was significantly taller in MSCT patients compared to cadavers.
  • The most frequent location for the VV was the anterior wall of the coronary sinus in both groups.

Conclusions:

  • The Vieussens valve is a common cardiac structure with significant morphological variability.
  • Large Vieussens valves, which can impede catheterization, are potentially visible with standard contrast-enhanced cardiac MSCT.

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Heart Valves

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Microbial Morphologies

Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
