Perioperative Anticoagulation Bridging

Anticoagulation Bridging: Assessment of thrombotic vs. bleeding risk. The modern standard (BRIDGE trial) favors holding therapy without heparin coverage for most patients.

1. Primary Condition

2. Risk Granularity

CHA₂DS₂-VASc Score0

Consensus Strategy

No Bridging Needed

Thrombotic Risk

Low Risk

The risk of major bleeding from bridging outperforms the thrombotic benefit. Hold VKA as per surgery type.

When to Use

Defining the need for heparin bridging (LMWH/UFH) in patients on Vitamin K Antagonists (Warfarin) undergoing surgery.

Assessing the thrombotic risk of interrupting anticoagulation.

Reducing the hazard of perioperative thromboembolism vs. major bleeding.

The 'BRIDGE' Trial Shift

The BRIDGE trial demonstrated that for the majority of patients with AF (low-to-moderate risk), bridging does not reduce stroke but SIGNIFICANTLY increases major bleeding. Bridging is now reserved for "High Risk" cohorts only.

How it Works

Thrombotic Risk Classes

Risk Class	AF (CHA₂DS₂-VASc)	VTE History	Mechanical Valve
High (Bridge)	≥ 7 or recent Stroke	VTE < 3 months ago	Any Mitral Valve
Moderate	5 - 6	VTE 3 - 12 months ago	Aortic (bileaflet) + risk factor
Low (No Bridge)	0 - 4	VTE > 12 months ago	Aortic (bileaflet)

Post-Op Restart

Following high-bleeding-risk surgery, wait 48–72 hours before restarting full-dose anticoagulation.
