Bystander Effect02:09

Bystander Effect

10.1K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

DC Battery

A conductor needs to be a component of a path that creates a closed loop or full circuit to have a continuous current flowing through it. A current starts to flow if an electric field is created inside an isolated conductor that is not part of a full circuit. The conductor quickly develops a net positive charge at one end and a net negative charge at the other. These charges generate an electric field opposite the direction of the applied electric field, which reduces the current. Eventually,...

Ethics and Bioethics01:22

Ethics and Bioethics

2.6K
Ethics is a philosophical study of moral actions. Ethics attempts to determine what is valuable for individuals and society. It examines the rational justification of moral judgments and analyzes what is morally just, fair, and right. Bioethics is a sub-discipline of applied ethics that analyzes the philosophical, social, and legal issues in life sciences and medicine. Ethical theories serve as a foundation for decision-making and represent the viewpoints from which people seek direction. They...

Deindividuation00:57

Deindividuation

30.1K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Dark Triad and Person Perception01:29

Dark Triad and Person Perception

194
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

Magical Thinking01:29

Magical Thinking

152
Magical thinking encompasses the belief in assumptions that defy logical reasoning yet appear intuitively convincing. It is a common psychological phenomenon that persists across various cultural and individual contexts. While these assumptions contradict empirical evidence and scientific laws, they often serve meaningful psychological roles in promoting emotional resilience and a sense of control, especially under stress or uncertainty.Thought-Action Fusion and the Law of SimilarityA key...

Summary
This summary is machine-generated.

The BATMAN technique prevents left ventricular outflow tract obstruction during transcatheter mitral valve replacement by apex-based deployment. Alternative methods like leaflet laceration or septal ablation also mitigate this risk.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology
  • Medical Device Technology

Background:

  • Transcatheter mitral valve replacement (TMVR) aims to treat mitral valve disease non-invasively.
  • Left ventricular outflow tract (LVOT) obstruction is a significant complication during TMVR.
  • Existing techniques for LVOT prevention require further optimization.

Discussion:

  • The BATMAN technique offers a novel approach to deploy TMVR devices via an apical trans-leaflet route.
  • Careful balloon dilatation is crucial to avoid leaflet tear extension into critical structures like the aorto-mitral curtain or trigone.
  • Understanding the anatomical risks associated with leaflet manipulation is paramount for procedural safety.

Key Insights:

  • BATMAN technique: Apex-based deployment through anterior mitral leaflet perforation to prevent LVOT obstruction in TMVR.
  • Risk mitigation: Uncontrolled balloon dilatation can lead to leaflet tear extension, potentially causing severe complications.
  • Alternative strategies: Percutaneous leaflet laceration, alcohol septal ablation, and transatrial leaflet resection are viable LVOT prevention methods.

Outlook:

  • Further research is needed to evaluate the long-term efficacy and safety of the BATMAN technique.
  • Comparative studies are essential to determine the optimal strategy for LVOT obstruction prevention in TMVR.
  • Advancements in device design and deployment techniques may further reduce TMVR-related complications.
