1 Introduction
Venous Thromboembolism (VTE), the combined syndromes of deep vein throm-
bosis (DVT) and pulmonary embolism (PE), is currently the third most frequent
acute cardiovascular syndrome globally behind myocardial infarction and stroke
[1]. In the past decade we have seen a remarkable improvement in new diagnostic
tools as well as novel therapeutic options to manage patients with VTE.
Multiple societies from around the globe have published guidelines for the
management of VTE. The most recently updated document is the 2019 European
SocietyofCardiology(ESC)guidelinesforthediagnosisandmanagementofacute
pulmonary embolism which was developed in collaboration with the European
Respiratory Society (ERS) [2]. A major limitation of the currently published
guidelines is its complexity.
To aid health care providers caring for patients with acute PE, our team
developed a novel, comprehensive yet straightforward, pathway for the manage-
ment of patients with PE, which we believe can be used in many health care
systems around the globe [3].
The necessity todevelop such apathwayat ourinstitution was compelling, and

be emphasized that this pathway is the opinion of our group and may differ
somewhat from the published guidelines.
Our pathway for the diagnosis and management of pulmonary embolism is
divided into three steps as demonstrated in Fig. 1:
Step 1: Diagnosis of PE (top third of pathway)
Step 2: Acute management of patients with PE (middle third of pathway)
Step 3: Recommendations for the chronic management of patients with PE (the
bottom third of the pathway).
Ineachstepweproposekeyquestionsthatleadto“yes”and“no”answerswhich
will further aid the health care providers to easily navigate the pathway.
The Pulmonary Embolism Response Team (PERT) is a multispecialty team
involved in the decision-making for the individual patient. The ESC guidelines
recommend establishment of a team of experts to convene for every case of
intermediate or high risk pulmonary embolism. The composition of the team
depends on the local resources and expertise. The PERT team brings together
specialists from different disciplines including, but not limited to, cardiology,
pulmonology, Emergency Medicine, hematology, vascular medicine,
anaesthesiology/intensive care, cardiothoracic surgery, and interventional radiol-
ogy. The team convenes in real time (via a platform such as WhatsApp or text
messages)tocommunicateclinicaldata,discusstheoptionsandprovideconsensus
for a course of management. By directly involving the expert clinicians, the team
facilitates the immediate implementation of the care plan [4].
2 Description of the Pathway
In most cases, patients with PE present with dyspnea, chest pain, pre-syncope or
syncope, or hemoptysis. However, in other cases, the signs and symptoms may be
non-specific.
A. Acute management of hemodynamically unstable patients (Fig. 2)
The first action is to assess the hemodynamic status in any patient with suspected
PE. Hemodynamic instability is defined as one of the following:
1. Presentation following cardiac arrest or current need for cardiopulmonary
resuscitation.
2. Obstructiveshock—definedassystolicBP <90 mmHgorvasopressorsrequired
to achieve a BP >90 mmHg despite adequate filling status AND end organ
hypoperfusion(alteredmentalstatus,cold,clammyskin,oligo-anuria,increased
serum lactate).
3. Persistent hypotension- defined as systolic BP <90 mmHg or systolic BP drop
>40 mmHg from baseline, lastinglonger than 15 min and notcaused byanew
onset arrhythmia, hypovolemia or sepsis.

In patients with hemodynamic instability, the most useful initial test is bedside
transthoracic echocardiography (TTE). The bedside TTE will show evidence of

can be achieved by thrombolysis and/or embolectomy. Thrombolysis can be
achieved by a systemic treatment or preferably by a catheter directed treatment.
Embolectomy can be performed surgically or by a catheter directed approach.
Following reperfusion treatment and hemodynamic stabilization, the patient
should be hospitalized in a critical care unit. As patients continue to recover, they
can be switched from parenteral to oral anticoagulation before discharge home.
