Insights

Surgical unroofing of myocardial bridges (MBs) in pediatric patients is safe and effective. This procedure relieved refractory anginal symptoms in most patients, improving their quality of life.

Area of Science:

  • Cardiology
  • Pediatric Surgery

Background:

  • Myocardial bridges (MBs) are often incidental findings, but symptomatic cases in adults can benefit from surgical unroofing.
  • Limited data exists on the efficacy of unroofing for MBs in the pediatric population.

Purpose of the Study:

  • To evaluate the indications and outcomes of surgical unroofing for myocardial bridges in pediatric patients.
  • To assess the safety and effectiveness of unroofing in this demographic.

Main Methods:

  • Retrospective review of pediatric patients who underwent surgical relief for MBs between 2012 and 2016.
  • Evaluation of clinical characteristics, diagnostic data, intraoperative findings, and postoperative outcomes.

Main Results:

  • 14 pediatric patients underwent unroofing of left anterior descending artery MBs.
  • 13 symptomatic patients experienced symptom resolution post-surgery, with improved quality of life.
  • Unroofing was performed both with and without cardiopulmonary bypass (CPB) without complications.

Conclusions:

  • Surgical unroofing of MBs is a safe procedure in pediatric patients, applicable with or without CPB.
  • Unroofing effectively relieves refractory symptoms in symptomatic pediatric patients with MBs.

Design Example: Strain Gauge Bridge or Wheatstone Bridge

The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

Wheatstone Bridge01:29

Wheatstone Bridge

An ohmmeter is a resistance-measuring device. It works by applying a voltage to a resistor of unknown resistance and measuring the current across the resistor. The resistance value is deduced using Ohm's law. Usually, the standard configuration of an ohmmeter comprises a voltmeter or an ammeter. However, such configurations are limited in accuracy because the meters alter the voltage applied to the resistor and the current that flows through it.
Thus, for accurate resistance measurements, a...

Bridge rectifier01:24

Bridge rectifier

The bridge rectifier is essential in electronics for efficiently converting alternating current (AC) to direct current (DC). Comprised of four diodes configured in a bridge layout, this rectifier effectively processes both the positive and negative halves of the AC waveform, making it superior to half-wave and full-wave center-tapped rectifiers in terms of voltage regulation and output stability.
Operationally, the bridge rectifier allows current flow through two of its diodes during each...

Cross-bridge Cycle01:26

Cross-bridge Cycle

As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?01:25

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.
