Abstract

Insights

The MitraClip procedure offers a viable treatment for severe mitral regurgitation (MR), showing modest improvements in patient function and pulmonary pressure with low procedural risks.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • The MitraClip procedure is an emerging alternative for high-risk patients suffering from mitral regurgitation (MR).
  • This minimally invasive approach is suitable for both functional MR (FMR) and degenerative MR (DMR) when specific mitral valve anatomy is present.

Purpose of the Study:

  • To assess the outcomes of the MitraClip procedure at our institution.
  • Focus on carefully selected patients with severe mitral regurgitation.

Main Methods:

  • Retrospective analysis of medical records and echocardiography data.
  • Data collected from January 2012 to December 2017.
  • Involved 39 MitraClip procedures in 37 patients.

Main Results:

  • 86.1% of patients achieved moderate to low mitral regurgitation post-procedure, with an 88.8% immediate device success rate.
  • One-year survival was 86%, with functional status (NYHA class) improving in 37% of patients.
  • Systolic pulmonary pressure decreased significantly at 1 month and remained reduced at 12 months.

Conclusions:

  • MitraClip provides a modest improvement in functional status and pulmonary pressure for severe MR patients.
  • The procedure carries a small risk of immediate complications, with encouraging outcomes compared to surgical intervention risks.

Lattice Centering and Coordination Number

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.

Center of Gravity

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...

Center of Gravity01:15

Center of Gravity

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...

Center of Mass

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...

Long-term Depression01:05

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Blind Procedures02:07

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
