Summary
Three-dimensional (3D) printing aids complex cardiac surgery planning. Patient-specific 3D models improve surgical planning for heart valve procedures, potentially reducing surgery time and infection risk.
Area of Science:
- Cardiovascular Surgery
- Medical Technology
- Biomedical Engineering
Background:
- The application of 3D printing technology in planning complex cardiac surgeries is an emerging area.
- 3D printing offers patient-specific anatomical models for surgical rehearsal.
Purpose of the Study:
- To systematically review the literature on the use and benefits of 3D printing in heart valve surgery.
- To analyze the impact of 3D printing on surgical planning and patient outcomes in this field.
Main Methods:
- Systematic literature review adhering to Preferred Reporting Items for Systematic Review guidelines.
- Searched databases including PubMed, EMBASE, Scopus, Web of Science, and Lilacs for relevant studies.
- Included articles on "Heart Valves," "Heart Valve Prosthesis Implantation," and "Printing, Three-Dimensional."
Main Results:
- Identified 301 articles and 13 case reports/series meeting inclusion criteria.
- Included studies encompassed 34 patients ranging from 3 months to 94 years of age.
- No studies with a large patient cohort were found.
Conclusions:
- Patient-specific 3D-printed models facilitate detailed surgical planning for heart valve procedures.
- This planning allows for optimal selection of surgical materials, size, and format.
- Benefits include reduced surgery duration, decreased patient exposure, and a lower risk of infection.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

01:20Random and Systematic Errors
14.5K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

01:16Heart Valves
11.3K
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...

12.6K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...
