Venous Thrombosis III: Interprofessional Care

481
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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

2.5K
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Summary

Performing balloon aortic valvuloplasty (BAV) without heparin significantly reduces vascular and bleeding complications. This heparin-free approach lowers adverse events without increasing ischemic risk, suggesting a safer BAV procedure.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Vascular and bleeding complications are primary adverse events following balloon aortic valvuloplasty (BAV).
  • Minimizing these complications is crucial for improving patient outcomes after BAV.

Purpose of the Study:

  • To evaluate the safety and efficacy of performing BAV without heparin.
  • To determine if omitting heparin during BAV reduces vascular and bleeding complications.

Main Methods:

  • A registry of 162 patients with severe aortic stenosis undergoing femoral BAV was analyzed.
  • Patients were divided into two groups: those receiving unfractionated heparin (UH) and those not receiving heparin.
  • The primary endpoint was a composite of severe vascular or bleeding complications, ischemic events, or death at 1-month follow-up.

Main Results:

  • The heparin-free group showed a significantly lower rate of the primary composite endpoint (10.3% vs. 20.0%, P=.03).
  • Vascular, bleeding, and ischemic events were substantially lower in the heparin-free group (6.5% vs. 18.8%, P=.01).
  • Heparin use was independently associated with an increased risk of vascular and bleeding complications (aOR, 2.94).

Conclusions:

  • Balloon aortic valvuloplasty performed without heparin is associated with reduced severe vascular events and death.
  • The heparin-free approach did not increase the risk of ischemic events.
  • Further confirmation in a randomized controlled trial is warranted to validate these findings.
