Summary
Minimally invasive left ventricular assist device (LVAD) implantation via lateral thoracotomy shows comparable survival to sternotomy. This approach may reduce complications like infections and is a viable option, especially for bridge-to-transplant candidates.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Procedures
- Mechanical Circulatory Support
Background:
- Minimally invasive left ventricular assist device (LVAD) implantation may reduce complications associated with traditional sternotomy.
- This study evaluates the initial outcomes of a minimally invasive LVAD technique using lateral thoracotomy (LT).
Purpose of the Study:
- To compare the outcomes of LVAD implantation using a minimally invasive lateral thoracotomy approach versus a conventional median sternotomy.
- To assess the feasibility and safety of the minimally invasive LVAD technique.
Main Methods:
- Retrospective analysis of 70 HeartWare LVAD implantations (22 LT, 48 sternotomy).
- Comparison of perioperative survival, adverse events, and complications between the LT and sternotomy groups.
Main Results:
- No significant difference in survival between LT and sternotomy groups (p=0.43).
- The LT group had fewer LVAD-related infections (p=0.04) and no wound dehiscence.
- LT patients without temporary right ventricular assist device (tRVAD) showed improved survival (p=0.02).
Conclusions:
- Minimally invasive LVAD implantation via lateral thoracotomy is a feasible alternative.
- This approach can potentially reduce complications and is particularly suitable for bridge-to-transplant patients.

The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...

The center of mass is the point at which the total mass of an object can be said to be concentrated. It is a fundamental principle in mechanics and physics that applies to all objects regardless of their shape or size. The center of gravity is the point at which an object’s weight appears to be concentrated and can be used to balance the object perfectly.
The knowledge of the center of mass can also help us to describe and predict the motion of objects. For example, when a ball is thrown...

An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

General plane motion, often observed in a rolling wheel, refers to a type of movement where the wheel is simultaneously rotating and translating. This complex motion can be understood by breaking it down into individual components.
To analyze this, consider two points on the wheel: point A and point B. The absolute velocity of point B can be expressed as the vector sum of the absolute velocity of point A and the relative velocity of point B with respect to point A. To simplify this analysis,...
