Summary
Bioresorbable vascular scaffolds (BVS) show promise for coronary artery interventions, especially in complex bifurcation lesions. Early experience suggests a provisional one-scaffold approach yields excellent results, supporting further investigation in challenging cases.
Area of Science:
- Cardiovascular medicine
- Biomaterials science
- Interventional cardiology
Background:
- Bioresorbable scaffolds (BVS) offer theoretical advantages over traditional metallic stents in percutaneous coronary interventions.
- Potential benefits include avoiding permanent vessel caging, malapposition, and hypersensitivity reactions, particularly in complex bifurcation lesions.
Purpose of the Study:
- To evaluate the feasibility and outcomes of using bioresorbable scaffolds in selected coronary bifurcation lesions.
- To assess the potential of BVS to address limitations of metallic stents in challenging coronary anatomies.
Main Methods:
- Retrospective analysis of clinical experience with bioresorbable scaffolds in bifurcation lesions.
- Evaluation of both one-scaffold (provisional) and two-scaffold techniques.
Main Results:
- The provisional one-scaffold technique demonstrated excellent results in selected bifurcation lesions.
- Two-scaffold techniques were found to be feasible for complex bifurcation interventions.
Conclusions:
- Bioresorbable scaffolds show potential for treating complex coronary bifurcation lesions.
- Further prospective studies and randomized trials are needed to confirm the long-term clinical benefits of BVS in these challenging cases.

01:12What is an Experiment?
19.1K
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...

01:25Personal Identity
467
Personal identity is the deeply felt sense of self that individuals cultivate over time, intricately woven from intrinsic qualities they consider essential to their existence—qualities such as morality, intelligence, and friendliness. These attributes serve as vital internal benchmarks, guiding individuals in evaluating whether their actions resonate with their true selves.When personal identity takes center stage in one's life, individuals often emphasize their distinctiveness,...

01:27Psychodynamic Perspectives on Personality
1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.

01:22Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

01:19Thomson's e/m Experiment
6.9K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

01:13Controls in Experiments
18.5K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...
