Cardiovascular System Abnormal Findings I: Inspection and Palpation

In a cardiovascular examination, inspection and palpation are crucial for identifying abnormalities.

Pulse01:16

Pulse

1.3K
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Pulse Assessment Sites

1.6K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Summary

Giant C-V waves in jugular venous pulse were observed in a young man post-bidirectional cavopulmonary (Glenn) shunt. This novel finding, linked to open antegrade flow, represents a previously undescribed complication of the Glenn procedure.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Cardiovascular Surgery

Background:

  • Bidirectional cavopulmonary (Glenn) shunt is a palliative procedure for complex congenital heart disease.
  • Open antegrade flow is a desired outcome post-Glenn shunt.
  • Jugular venous pulse abnormalities can indicate hemodynamic changes.

Purpose of the Study:

  • To describe a novel presentation of giant C-V waves in the jugular venous pulse following a Glenn procedure.
  • To highlight a previously unrecognized phenomenon associated with open antegrade flow after cavopulmonary shunting.

Main Methods:

  • Case report of a young male patient.
  • Clinical observation of neck and pinna pulsations.
  • Analysis of jugular venous pulse waveform.

Main Results:

  • The patient exhibited visible neck and pinna pulsations.
  • Giant C-V waves were identified in the jugular venous pulse.
  • These findings were directly associated with the palliative bidirectional cavopulmonary (Glenn) shunt with open antegrade flow.

Conclusions:

  • Giant C-V waves represent a novel, previously undescribed entity following a Glenn procedure.
  • This phenomenon is linked to open antegrade flow, suggesting specific hemodynamic implications.
  • Recognition of this finding is crucial for appropriate patient management and understanding of Glenn shunt physiology.
