Aneurysms of lobar branches of pulmonary artery are extremely rare with few reported cases in literature. The exact etiopathogenesis of pulmonary artery aneurysms is not clearly understood and no clear guidelines on their management is available. Aneurysms of the secondary and tertiary branches appear to be even more uncommon than those of the trunk and primary branches. Here we report an unusual case of young female with multiple pulmonary artery aneurysms in bilateral lungs with fusiform dilation of main pulmonary trunk and a small patent ductus arteriosus.

Aims: Outcome in pulmonary arterial hypertension (PAH) is determined by right ventricular (RV) function adaptation to increased afterload. Echocardiography is easily available to assist bedside evaluation of the RV. However, no agreement exists about the feasibility and most relevant measurements.

Pulmonary artery choriocarcinoma mimicking pulmonary thromboembolism: a case report.

Background: Primary choriocarcinoma of the pulmonary artery is an exceedingly rare malignant neoplasm, which is often misdiagnosed due to its nonspecific clinical presentation. While this condition is characterized by the presence of trophoblastic cells, typically associated with gestational trophoblastic diseases, we encountered a case occurring in an extragenital location. The rarity of such tumors makes it challenging for clinicians to consider them in differential diagnosis, especially when the initial symptoms mimic more common conditions such as pulmonary thromboembolism (PTE).

Right Ventricular Function and Outcomes Stratified by the Effective Regurgitant Orifice Area in Secondary Tricuspid Regurgitation.

Can J Cardiol

January 2025

Department of Cardiology, Istituto Auxologico Italiano, IRCCS, Milan, Italy; Department of Medicine and Surgery, University of Milano- Bicocca, Milan, Italy.

Background: In patients with moderate and severe secondary tricuspid regurgitation (STR), the effective regurgitant orifice area (EROA), corrected using the proximal isovelocity surface area (PISA) method for tricuspid valve leaflet tethering and low TR jet velocities, has an unclear threshold for identifying high-risk patients. This study aimed to establish a risk-based EROA cutoff and assess the impact of right ventricular (RV) remodeling on outcomes in low-risk STR patients according to EROA.

Methods: We included 513 consecutive outpatients (age 75±13 years, 47% male) with moderate and severe STR.

1,8-Cineole reduces pulmonary vascular remodelling in pulmonary arterial hypertension by restoring intercellular communication and inhibiting angiogenesis.

Comba, Coimbra 3000-548, Portugal; Univ Coimbra, Center for Innovative Biomedicine and Biotechnology (CIBB), Coimbra, Portugal; Clinical Academic Centre of Coimbra (CACC), Coimbra, Portugal.

Background: Pulmonary Arterial Hypertension (PAH) is characterized by pulmonary vascular remodelling, often associated with disruption of BMPR2/Smad1/5 and BMPR2/PPAR-γ signalling pathways that ultimately lead to right ventricle failure. Disruption of intercellular junctions and communication and a pro-angiogenic environment are also characteristic features of PAH. Although, current therapies improve pulmonary vascular tone, they fail to tackle other key pathological features that could prevent disease progression.

Objective: A significant number of patients with chronic thromboembolic pulmonary hypertension (CTEPH) are not eligible for pulmonary endarterectomy and may be treated with balloon pulmonary angioplasty (BPA). Although BPA programs have recently been developed in Brazil, no results have yet been published. The objective of this study was to assess the clinical and hemodynamic progression of the first patients treated with BPA at our center.
