Acute Coronary Syndrome III: Diagnostic Studies01:30

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Assessment of the Cardiovascular System IV: Auscultation01:25

Assessment of the Cardiovascular System IV: Auscultation

Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.

Summary
This summary is machine-generated.

Experienced clinicians can reliably assess right ventricular (RV) function visually, showing good agreement with quantitative measures like fractional area of change (FAC). This supports visual assessment in critical care echocardiography.

Area of Science:

  • Cardiology
  • Critical Care Medicine
  • Echocardiography

Background:

  • Right ventricular (RV) dysfunction is a key factor in circulatory failure among critically ill patients.
  • Accurate diagnosis of RV dysfunction is crucial for effective management.
  • The reliability of visual assessment for RV function in echocardiography is often debated.

Purpose of the Study:

  • To evaluate the concordance between visual grading of RV systolic function, size, and septal motion.
  • To compare visual assessments with standard quantitative echocardiographic parameters.
  • To determine the reliability of visual assessment across different levels of echocardiography expertise.

Main Methods:

  • A multicenter international prospective study involving 115 critically ill patients.
  • Transthoracic echocardiography recordings were reviewed by 73 raters with varying expertise.
  • Visual assessments of RV function, size, and septal motion were compared with quantitative parameters including FAC, TAPSE, S' wave, and RVFWLS.

Main Results:

  • Strong agreement between visual grading and fractional area of change (FAC) was observed for experts (κ = 0.73) and intermediates (κ = 0.64).
  • Moderate agreement was found for RV size and visual assessment with RV basal diameter and RV/LV area ratio.
  • Low concordance was noted for septal motion and visual assessment with RV/LV basal diameter ratio.

Conclusions:

  • Visual assessment of RV function by experienced raters demonstrates satisfactory concordance with guideline-based FAC.
  • This finding supports the integration of visual RV function assessment into multiparametric evaluations.
  • Structured educational programs can enhance the reliability of visual echocardiographic assessments.
