Insights

A rare aorto-right atrial fistula from penetrating trauma, evolving over 16 years, presented with acute coronary syndrome. Surgical correction combined with myocardial revascularization successfully treated this complex cardiac injury.

Area of Science:

  • Cardiovascular Surgery
  • Trauma Surgery
  • Cardiology

Background:

  • Aorto-atrial fistulas are uncommon but life-threatening consequences of cardiac trauma.
  • Prompt surgical intervention is critical for survivors of aorto-cameral fistulas.

Observation:

  • A 16-year evolution of a penetrating trauma resulted in an aorto-right atrial fistula.
  • The patient presented with symptoms indicative of acute coronary syndrome.

Findings:

  • Successful surgical correction of the aorto-cameral fistula was achieved.
  • Myocardial revascularization was performed concurrently with fistula repair.

Implications:

  • This case highlights the potential for delayed presentation of aorto-atrial fistulas.
  • Complex cardiac trauma management requires a multidisciplinary approach.
  • Long-term surveillance may be necessary for patients with repaired aorto-cameral defects.

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.

Traumatic Memory01:20

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Regional Terms01:12

Regional Terms

Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Long-Term Memory01:18

Long-Term Memory

Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
