Isolated left ventricular noncompaction diagnosed by transthoracic threedimensional echocardiography
1Department of Ultrasound, The First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou, China.
Summary
Three-dimensional echocardiography (3DE) improved diagnosis of left ventricular noncompaction (NVM) in a patient with chest distress. 3DE revealed prominent trabeculations and recesses, unlike 2DE, confirming NVM criteria.
Area of Science:
- Cardiology
- Medical Imaging
- Echocardiography
Background:
- Chest distress associated with activity can indicate cardiac abnormalities.
- Diagnosing rare conditions like left ventricular noncompaction (NVM) can be challenging with standard imaging.
- Two-dimensional echocardiography (2DE) may not always provide sufficient detail for NVM diagnosis.
Purpose of the Study:
- To evaluate the diagnostic utility of three-dimensional echocardiography (3DE) in a suspected case of left ventricular noncompaction (NVM).
- To compare the effectiveness of 3DE versus 2DE in visualizing left ventricular myocardial structure.
Main Methods:
- A 55-year-old male patient presented with activity-related chest distress.
- Two-dimensional echocardiography (2DE) was performed, showing ambiguous findings of left ventricular apex trabeculations.
- Three-dimensional echocardiography (3DE) was subsequently utilized for enhanced visualization.
Main Results:
- 2DE findings were inconclusive for NVM, showing suspected trabeculation but not meeting diagnostic criteria.
- 3DE revealed more prominent trabeculations and deeper intertrabecular recesses in the left ventricular apex.
- 3DE findings were consistent with the diagnostic criteria for NVM.
Conclusions:
- Three-dimensional echocardiography (3DE) offers superior visualization of left ventricular myocardial morphology compared to 2DE.
- 3DE is a valuable tool for diagnosing left ventricular noncompaction (NVM), providing comprehensive, pyramid-shaped datasets.
- Advanced echocardiographic techniques like 3DE are crucial for accurate diagnosis of complex cardiac conditions.

Diagnosing acid-base imbalances involves systematically analyzing arterial blood samples, focusing on three key measurements: pH, bicarbonate (HCO3−) concentration, and carbon dioxide partial pressure (PCO2). This analysis follows a four-step process that helps identify the imbalance's underlying cause and nature.
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Dimensional analysis is a valuable technique in fluid mechanics for simplifying complex problems by reducing them into dimensionless groups. These groups capture the essential relationships between the variables involved, allowing researchers and engineers to analyze fluid flow without dealing with each variable individually. This approach reduces the number of independent variables, allowing for easier analysis and better understanding of physical phenomena.

Dimensional analysis is a powerful tool that is used in physics and engineering to understand and predict the behavior of physical systems. The basic idea behind dimensional analysis is to express physical quantities in terms of fundamental dimensions such as the mass, length, and time. Derived dimensions like the velocity, acceleration, and force are derived from the combinations of these fundamental dimensions.

The concept of dimension is important because every mathematical equation linking physical quantities must be dimensionally consistent, implying that mathematical equations must meet the following two rules. The first rule is that, in an equation, the expressions on each side of the equal sign must have the same dimensions. This is fairly intuitive since we can only add or subtract quantities of the same type (dimension). The second rule states that, in an equation, the arguments of any of the...
