Insights

Chronic thromboembolic pulmonary hypertension (CTEPH) and related vascular disease (CTED) are rare but treatable conditions. Effective treatments include surgery, angioplasty, and approved medications like Riociguat and treprostinil.

Area of Science:

  • Cardiovascular Medicine
  • Pulmonary Medicine
  • Vascular Surgery

Background:

  • Chronic thromboembolic pulmonary hypertension (CTEPH) and chronic thromboembolic pulmonary vascular disease (CTED) represent uncommon but serious outcomes of venous thromboembolism.
  • These conditions are hypothesized to stem from a shared underlying pathophysiological process.

Purpose of the Study:

  • To summarize the current understanding and treatment landscape for CTEPH and CTED.
  • To highlight the efficacy of available therapeutic interventions.

Main Methods:

  • Review of existing literature on CTEPH and CTED pathophysiology and treatment.
  • Analysis of approved pharmacological and interventional therapies.

Main Results:

  • CTEPH and CTED are rare manifestations of venous thromboembolism, likely sharing a common pathophysiological basis.
  • Significant clinical improvement, approaching a cure, can be achieved through pulmonary endarterectomy, balloon pulmonary angioplasty, and medical therapies.

Conclusions:

  • Pulmonary endarterectomy and balloon pulmonary angioplasty are effective interventional treatments for CTEPH and CTED.
  • Pharmacological options including Riociguat and subcutaneous treprostinil offer approved medical management strategies for these conditions.

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
