Summary
Detailed anatomical measurements of the pulmonary valve root reveal its asymmetrical structure. This provides crucial spatial geometrical data for the Ross procedure, enhancing surgical understanding.
Area of Science:
- Cardiovascular Anatomy
- Surgical Anatomy
- Medical Imaging
Background:
- The Ross procedure's resurgence highlights the need for detailed pulmonary valve anatomy.
- Existing literature primarily focuses on pulmonary root morphology, lacking specific anatomical data.
- This study addresses the gap by detailing the cardiosurgical anatomy of the pulmonary valve.
Purpose of the Study:
- To provide a comprehensive cardiosurgical-oriented anatomical description of the pulmonary valve.
- To quantify key morphometric parameters of the pulmonary root.
- To construct a spatial geometrical model of the pulmonary root's structure.
Main Methods:
- Morphometric measurements were performed on 20 fixed normal pulmonary roots.
- Measurements were taken under diastolic pressure with closed leaflets.
- Key parameters included distances between commissures, intervalvular triangles, sinus heights, and intervalvular triangle heights.
Main Results:
- Pulmonary root commissure and intervalvular triangle distances at the base were similar.
- The left coronary sinus was the highest, followed by the right and anterior sinuses.
- A tilt angle of 16.26 degrees between the root base and sinotubular junction was identified.
Conclusions:
- A spatial geometrical model of the pulmonary root was constructed based on measured parameters.
- The model clearly illustrates the asymmetrical structure of the pulmonary root.
- This detailed anatomical data is vital for the Ross procedure and understanding pulmonary valve function.
