Chambers of the Heart01:16

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Blood Flow01:29

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Area of Science:

  • Plastic Surgery
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Ear reconstruction using autologous rib cartilage is a multi-stage process.
  • Ensuring adequate blood flow restoration between surgical stages is vital for successful outcomes.
  • Assessing microvascular recovery is key to evaluating reconstructive surgery efficacy.

Purpose of the Study:

  • To evaluate the recovery of skin blood flow in unilaterally reconstructed ears.
  • To compare blood perfusion and thermal response between reconstructed and normal ears.
  • To determine if blood flow dynamics normalize after a three-stage ear reconstruction.

Main Methods:

  • Utilized Laser Doppler Perfusion Imaging (LDPI) to measure blood flow.
  • Recorded local ear temperature.
  • Applied indirect heating to assess dynamic vascular response in ten patients post-reconstruction.

Main Results:

  • No significant difference in Laser Doppler Perfusion Imaging (LDPI) values between reconstructed and normal ears.
  • Both reconstructed and normal ears demonstrated similar increases in blood flow and temperature upon indirect heating.
  • The reconstructed ear was slightly warmer in the upper part compared to the normal ear initially.

Conclusions:

  • Skin blood flow recovery is achieved after a three-stage autologous rib cartilage ear reconstruction.
  • The reconstructed ear exhibits a normal dynamic response to thermal stimuli, indicating successful vascularization.
  • Laser Doppler Perfusion Imaging (LDPI) is a viable tool for assessing microcirculatory recovery in ear reconstruction.
