Insights

The Tiger catheter in transradial coronary angiography (TRC) effectively reduces contrast volume and fluoroscopy time with fewer complications. While left coronary ostium engagement can be unstable, overall catheter stability is comparable to Judkins catheters.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Transradial coronary angiography (TRC) offers a minimally invasive approach for coronary artery visualization.
  • A one-catheter technique simplifies TRC procedures, targeting both right and left coronary ostia (R/LCO).
  • Evaluating specialized catheters like the Tiger II is crucial for optimizing TRC performance.

Purpose of the Study:

  • To assess the efficacy and safety of the Tiger II diagnostic catheter for one-catheter TRC.
  • To compare the performance of the Tiger catheter against Judkins catheters in TRC procedures.

Main Methods:

  • A dual-center registry analyzed 1412 TRC procedures performed by experienced operators.
  • Catheter performance was evaluated by retrospectively assessing ostial engagement stability.
  • Key metrics included contrast volume, fluoroscopy time (FT), and complication rates.

Main Results:

  • The Tiger catheter showed comparable ostial engagement success rates (59.5%) versus Judkins catheters (53.4%).
  • Tiger catheter use was associated with significantly lower contrast volume (63.48 mL vs. 82.51 mL) and shorter FT (198.27 sec vs. 326.85 sec).
  • Forearm hematomas were less frequent with the Tiger catheter (1.2% vs. 6.6%).

Conclusions:

  • The Tiger catheter is an effective single-catheter tool for TRC, reducing contrast and FT while maintaining a low complication rate.
  • While ostial instability predominantly affects the left coronary artery with the Tiger, its overall frequency is similar to Judkins catheters.

Self-Concept01:19

Self-Concept

Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Self-Efficacy

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Concept of Pressure at a Point01:15

Concept of Pressure at a Point

The concept of pressure at a point in a fluid establishes that pressure within a fluid is uniform in all directions at a specific location. This uniformity occurs because fluid molecules exert force evenly across any point due to their random motion and continuous collisions within the fluid. Pressure at a point is determined by the surrounding fluid molecules and is influenced by factors like depth and density, rather than by shape or orientation.
In a fluid at rest, pressure acts equally in...

Understanding Self-Concept01:20

Understanding Self-Concept

The self-concept encompasses individuals' beliefs about themselves, structured through cognitive frameworks known as self-schemas. These schemas function as mental representations of specific traits or behaviors, influencing how self-relevant information is perceived, processed, and remembered. For example, individuals who are schematic for body weight are more likely to interpret routine experiences—such as dining out or shopping—through the lens of that trait. Conversely, those...
