Abnormal Proliferation02:23

Abnormal Proliferation

5.3K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Heart Valves01:16

Heart Valves

12.5K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Conduct Disorder01:28

Conduct Disorder

622
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Conduction System of the Heart01:19

Conduction System of the Heart

13.7K
Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

Conduction System of the Heart01:20

Conduction System of the Heart

4.1K
The cardiac conduction system produces and transmits electrical impulses that prompt myocardial contraction, ensuring efficient heart function. This intricate system ensures that the heart beats in a coordinated and efficient manner, beginning with the atria and then the ventricles. The conduction system optimizes cardiac output by maintaining this precise sequence, which is crucial for adequate blood circulation.
This system relies on the unique properties of nodal and Purkinje cells:...

Electrical Conductivity01:13

Electrical Conductivity

1.8K
In perfect conductors, the electric field inside is always zero due to the abundance of free electrons, which nullify any field by flowing. As a result, any residual charge resides on the surface.
In a practical conductor, an applied electric field may be sustained, causing a flow of electrons, which produce a current. The differential form of the current, the current density, is related to the electric field.
More generally, it is related to the force per unit charge, which involves the...

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Cardiac Electrophysiology

Background:

  • Transcatheter aortic valve implantation (TAVI) is a growing alternative for severe aortic stenosis in high-risk patients.
  • Aortic valve anatomy is closely linked to the heart's conduction system, leading to potential complications post-TAVI.
  • Conduction system disturbances, including heart block and pacemaker needs, are frequent after TAVI.

Purpose of the Study:

  • To review the common complications of TAVI related to conduction system disturbances.
  • To identify risk factors associated with the development of these post-TAVI abnormalities.
  • To emphasize the importance of screening and prevention strategies.

Main Methods:

  • Review of current literature on TAVI and associated conduction disturbances.
  • Analysis of identified risk factors for post-TAVI conduction abnormalities.
  • Discussion of clinical implications and management strategies.

Main Results:

  • Conduction system disturbances are common after TAVI, ranging from bundle branch block to complete heart block.
  • Key risk factors include patient age, cardiac anatomy, procedural details, valve type, and pre-existing conditions.
  • While often not fatal, these disturbances significantly impact patient well-being and long-term survival.

Conclusions:

  • Careful patient screening for risk factors is crucial before TAVI.
  • Effective prevention and timely treatment of conduction abnormalities can improve TAVI outcomes.
  • Further research may refine risk stratification and management protocols for TAVI patients.
