Cardiac Catheterization III: Left Heart Catheterization

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Cardiac Catheterization II: Right Heart Catheterization

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...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Acute Coronary Syndrome IV: Interprofessional Care

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Coronary Artery Disease V: Interprofessional Care

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Background:

Accurate pulmonary arterial wedge pressure (PAWP) and cardiac output (CO) measurements are vital for diagnosing and managing pulmonary hypertension (PH) and pulmonary arterial hypertension (PAH).
Errors in PAWP and CO can lead to misclassification and inappropriate treatment.
Recent guidelines emphasize standardized right heart catheterization (RHC) practices.

Purpose of the Study:

Identify knowledge gaps in RHC practices among interprofessional teams.
Implement a blended learning program for fellows and nurses focusing on PAWP and CO acquisition and interpretation.
Enhance procedural competency and interpretation of RHC hemodynamic data.

Main Methods:

Utilized the SQUIRE framework for a baseline survey of RHC practices and knowledge among physicians and nurses.
Developed a 120-minute blended learning program based on survey results (lectures, video, simulation).
Conducted pre- and post-training assessments to evaluate knowledge improvement.

Main Results:

Baseline data revealed knowledge gaps in CO measurement and PAWP interpretation.
Post-training assessments showed improved knowledge in CO methods (iFick), zero-reference level confirmation, PAWP acquisition, and CO measurements.
Correct identification of end-expiratory PAWP decreased, indicating a need for focused reinforcement.

Conclusions:

This study represents the first interprofessional training initiative for RHC CO and PAWP accuracy.
The educational intervention successfully addressed key knowledge gaps and improved understanding.
Structured, ongoing interprofessional training is essential for optimizing PH and PAH patient care.
