Perioperative antiplatelet therapy management

• 1 000 000 patients undergo coronary stent implantation per year in UE and USA

• 15% and 25% patients undergo invasive or surgical procedurewithin 1 and 5 y post coronary stenting

Urgent surgery

• Surgery required within 48h

• Avoid platelets transfusion 4-6h after thienopyridine and 10-12 h after last intake ticagrelor

IN CLINICAL PRACTICE

In patients treated with VKAs:

Individualized bridging anticoagulation in specific high-

risk patients with a low bleeding risk procedure

70

WHICH PATIENTS ARE AT HIGH RISK OF THROMBOEMBOLISM

IN CASE OF TEMPORARY INTERRUPTION OF ORAL

ANTICOAGULATION ?

Mechanical mitral heart valve

Multiple mechanical heart valves

Mechanical aortic heart valve and additional risk

factors (history of thromboembolism, AF, heart failure,

dilated cardiomyopathy, intracardiac thrombus)

AF with history of stroke or TIA, left atrial appendage

thrombus

Venous thromboembolism 3 months

71

PROCEDURES CARRYING A HIGH RISK OF BLEEDING

Cardia surgery, major vascular surgery

Neurosurgery

Major surgery for cancer

Urology surgery: prostatectomy, nephrostomy,

nephrectomy, cystectomy

Colonoscopy with polypectomy

Endoscopic sphincterotomy

XA INHIBITORS

CONCLUSIONS 1

80

Periprocedural anticoagulation management often

leads to significant adverse events Bleeding is much more common than clotting

Bridging in patients treated with VKAs results in

periprocedural bleeding without reduction in

thromboembolism

80

CONCLUSIONS 2

In patients treated with VKAs:

Individualized bridging anticoagulation in specific high-risk

patients with a low bleeding risk procedure

In patients treated with DOACs:

No bridging unless oral anticoagulation resumption is

delayed after the procedure
