Heart Valves01:16

Heart Valves

12.3K
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...

What 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...

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

1.1K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Thomson'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...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

591
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Controls in Experiments01:13

Controls in Experiments

18.4K
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...

Area of Science:

  • Cardiovascular Surgery
  • Biomaterials Science
  • Medical Devices

Background:

  • Bioprosthetic aortic valve replacement (AVR) is increasingly common in elderly patients.
  • Pericardial prostheses offer improved durability and hemodynamic performance.
  • The Trifecta valve is a new-generation stented pericardial prosthesis for aortic valve replacement.

Purpose of the Study:

  • To evaluate the safety and early clinical outcomes of the Trifecta aortic prosthesis.
  • To assess the early hemodynamic performance of the Trifecta valve.
  • To establish the performance of this latest-generation bioprosthesis in AVR.

Main Methods:

  • Retrospective analysis of 373 patients undergoing Trifecta valve implantation (March 2014-March 2017).
  • Evaluation of pre-operative, operative, and post-operative data, including clinical outcomes.
  • Echocardiography data were collected to assess hemodynamic performance.

Main Results:

  • Early mortality was 5.36% (20 patients), with 1.07% late mortality.
  • Freedom from valve explant was 99.77% per late patient-year.
  • Postoperative mean gradients were acceptable at 10.63 mmHg, with no severe aortic regurgitation.

Conclusions:

  • The Trifecta aortic prosthesis demonstrates excellent early safety and hemodynamic outcomes.
  • Acceptable mean gradients suggest good hemodynamic performance.
  • Continued follow-up is warranted due to the valve's characteristics and patient population.
