Cardiac Catheterization II: Right Heart Catheterization01:21

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...

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
Pulmonary Embolism I: Introduction01:19

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

Area of Science:

  • Cardiology
  • Surgical Complications
  • Medical Imaging

Background:

  • Intraoperative pulmonary embolism is a rare but severe complication during cardiac surgery, particularly with right atrial masses.
  • A 62-year-old female patient with comorbidities presented with breathlessness, indicative of a cardiac issue.

Purpose of the Study:

  • To report the successful management of a patient experiencing intraoperative pulmonary embolism secondary to a right atrial mass.
  • To highlight the critical role of transesophageal echocardiography (TEE) in diagnosing and guiding surgical intervention for this complication.

Main Methods:

  • Preoperative echocardiography identified a mobile right atrial mass prolapsing through the tricuspid valve.
  • Intraoperative transesophageal echocardiography (TEE) was used to confirm hemodynamic collapse due to mass embolization.
  • Surgical approach was modified to include pulmonary thrombectomy under deep hypothermic circulatory arrest.

Main Results:

  • The patient experienced sudden hemodynamic collapse following anesthesia induction, confirmed as pulmonary embolism via intraoperative TEE.
  • The modified surgical procedure, including pulmonary thrombectomy, was successfully performed.
  • TEE was instrumental in real-time diagnosis and guiding critical surgical decisions.

Conclusions:

  • Successful management of intraoperative pulmonary embolism from a right atrial mass is achievable with prompt diagnosis and surgical intervention.
  • Transesophageal echocardiography (TEE) is an indispensable tool for intraoperative monitoring and decision-making in such complex cardiac surgical cases.
