Refined balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension - reference center experience.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH), characterized by thromboembolic changes affecting the pulmonary bed, leads to ventricular function deterioration and premature death. The introduction of balloon pulmonary angioplasty (BPA) has significantly improved the prognosis of CTEPH patients.

Aim: The authors of this article decided to summarize the experience of the BPA program, conducted between 2014 and 2022, at the reference center.

Plasma Troponins Identify Patients with Very Low-Risk Acute Pulmonary Embolism.

Introduction: Although in the non-vitamin K oral anticoagulants (NOAC) era majority of low-risk acute pulmonary embolism (APE) patients can be treated at home, identifying those at very low risk of clinical deterioration may be challenging. We aimed to propose the risk stratification algorithm in sPESI 0 point APE patients, allowing them to select candidates for safe outpatient treatment.

Materials And Methods: Post hoc analysis of a prospective study of 1151 normotensive patients with at least segmental APE.

Electrocardiogram, Echocardiogram and NT-proBNP in Screening for Thromboembolism Pulmonary Hypertension in Patients after Pulmonary Embolism.

Background: The annual mortality of patients with untreated chronic thromboembolism pulmonary hypertension (CTEPH) is approximately 50% unless a timely diagnosis is followed by adequate treatment. In pulmonary embolism (PE) survivors with functional limitation, the diagnostic work-up starts with echocardiography. It is followed by lung scintigraphy and right heart catheterization.

A Novel Doppler TRPG/AcT Index Improves Echocardiographic Diagnosis of Pulmonary Hypertension after Pulmonary Embolism.

Background: We hypothesized that a Doppler index, the ratio of tricuspid regurgitation peak gradient (TRPG) to pulmonary ejection acceleration time (AcT), improves the assessment of the echocardiographic probability of pulmonary hypertension in the identification of CTEPH and chronic thromboembolic pulmonary disease (CTED) in symptomatic patients after PE. Doppler echocardiography is recommended as the initial imaging tool for the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary embolism (PE).

Methods: We analyzed the data from 845 consecutive PE (468 women; 61 ± 18 years) survivors who completed at least 6 months of anticoagulation therapy.
