Venous Thrombosis I: Introduction01:30

Venous Thrombosis I: Introduction

634
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Venous Thrombosis III: Interprofessional Care

453
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Aneurysm III: Interprofessional Care

435
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

618
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...

Area of Science:

  • Cardiology
  • Biomedical Engineering

Background:

  • Transcatheter aortic valve implantation (TAVI) is increasingly used in younger, lower-risk patients.
  • Understanding TAVI valve thrombosis is crucial for preventing bioprosthetic valve dysfunction and thromboembolic events.

Purpose of the Study:

  • To review current evidence on TAVI valve thrombosis, including mechanisms, prevalence, clinical relevance, and management.
  • To highlight ongoing research and clinical trials focused on TAVI thrombosis detection and treatment.

Main Methods:

  • Literature review of existing evidence on TAVI valve thrombosis.
  • Analysis of challenges in subclassification and detection of valve thrombosis.
  • Examination of current and emerging treatment strategies.

Main Results:

  • Detection of TAVI valve thrombosis is challenged by imaging modality heterogeneity.
  • Long-term implications, including stroke risk and prosthesis longevity, remain uncertain.
  • Current treatments include anticoagulation, thrombolysis, and reintervention.

Conclusions:

  • Improved, standardized imaging protocols and intensified antithrombotic regimens are needed.
  • Better understanding of risk factors is essential for personalized antithrombotic therapy and prosthesis design.
  • Ongoing research aims to enhance TAVI thrombosis management and prevention.
