Pulmonary artery aneurysms (PAA) and pseudoaneurysms (PAP) are caused by infections, vasculitis, trauma, pulmonary hypertension, congenital heart disease, and connective tissue disease. Most cases of such aneurysm occur in the trunk or major branches of the pulmonary artery, while the peripheral type is less common. The treatment modalities are medical therapy, surgery, and percutaneous catheter embolization. The mortality rate associated with rupture is approximately 50%. We encountered a case of a 53-year-old man with a pulmonary artery pseudoaneurysm secondary to pneumonia and cavity formation during chemotherapy for acute myeloid leukemia (AML)...

According to recent studies, lung uptake of iodine-123-metaiodobenzylguanidine (123I-MIBG) is impaired in many lung diseases and low lung uptake of 123I-MIBG suggests endothelial dysfunction of the pulmonary artery. 123I-MIBG scintigraphy in patients with pulmonary hypertension (PH) has not yet been clinically evaluated. We hypothesized that the lung uptake of 123I-MIBG is reduced in patients with PH and differs among PH subtypes. The purpose of the present study was to analyze the lung uptake of 123I-MIBG in patients with PH and compare it with the data obtained by echocardiography or right heart catheterization...

BACKGROUND AND AIMS: The main stages of cirrhosis (compensated and decompensated) have been substaged based on clinical, endoscopic, and portal pressure (determined by the hepatic venous pressure gradient, HVPG) features. Vasodilatation leading to a hyperdynamic circulatory state is central in the development of a late decompensated stage with inflammation being currently considered a key driver. We aimed to assess hepatic/systemic hemodynamics and inflammation (by C reactive protein, CRP) among the different substages of cirrhosis and to investigate their interrelationship and prognostic relevance...

BACKGROUND: Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) has revolutionized the diagnostic approach to mediastinal diseases. Lesions located lateral to the pulmonary artery (trans-PA, Station 5), or in the lumen of the PA (intra-PA) are in the 'blind-spot' of EBUS. OBJECTIVES: We describe a case series where EBUS guided trans-pulmonary or intra-pulmonary aspiration (EBUS-TIPNA) was used for diagnosis. METHODS: Retrospective analysis of 10 patients who had EBUS-TIPNA over 3 years in 2 centers...

We have previously developed a simulated cardiovascular physiology model for in-silico testing and validation of novel closed-loop controllers. To date, a detailed model of the right heart and pulmonary circulation was not needed, as previous controllers were not intended for use in patients with cardiac or pulmonary pathology. With new development of controllers for vasopressors, and looking forward, for combined vasopressor-fluid controllers, modeling of right-sided and pulmonary pathology is now relevant to further in-silico validation, so we aimed to expand our existing simulation platform to include these elements...

Pulmonary arterial hypertension (PAH) is a rare disorder that can be drug-induced, mostly following treatment by appetite-suppressant drugs. We report four cases of patients who developed PAH following a treatment by leflunomide for rheumatoid arthritis, psoriatic arthritis or undetermined connective tissue disease. All patients described a progressive dyspnea from grade II to IV of NYHA classification; clinical examination found signs of heart failure. PAH was finally diagnosed and confirmed by right heart catheterisation...

Congenitally corrected transposition of the great arteries (ccTGA) can occur in isolation, or in combination with other structural cardiac anomalies, most commonly ventricular septal defect, pulmonary stenosis and tricuspid valve disease. Clinical recognition can be challenging, so echocardiography is often the means by which definitive diagnosis is made. The tricuspid valve and right ventricle are on the systemic arterial side of the ccTGA circulation, and are therefore subject to progressive functional deterioration...

BACKGROUND: Cell based therapy has been heralded as a novel, promising therapeutic strategy for cardiovascular diseases including pulmonary arterial hypertension (PAH). However, the low survival rate after transplantation due to cell death via anoikis is a major obstacle in stem cell therapy. Cells adhesion via Integrin alpha5beta1 (ITGA5B1) has a tendency to exert higher maximum forces. The present study aimed to evaluate the potential protective effect of ITGA5B1 on rat bone marrow mesenchymal stem cells (rBMSCs) from anoikis...

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) accounts for 0.4% of the congenital heart diseases. Comprehensive 2D and 3D transesophageal echocardiographic imaging of a well-collateralized subset of ALCAPA is described. A nonstandard short-axis view of both aorta and pulmonary arteries showed the origin of left coronary artery from the posterior sinus of the pulmonary artery and right coronary artery in its usual position. Pulse-wave interrogation of the coronary arteries showed the direction of flow in opposite directions...

Pulmonary hypertension (PH) is a relatively frequent and severe complication of sickle cell disease (SCD). PH associated with SCD is classified as Group 5 PH. The exact pathogenesis of PH in SCD in not known. There are also very limited treatment options available at this time for such patients with Group 5 PH. Patients with SCD are predisposed to a hypercoagulable state and thus can also suffer from chronic thromboembolism. These patients can have associated chronic thromboembolic pulmonary hypertension (CTEPH), thus being classified as Group 4 PH...

To enhance the understanding of the left coronary artery originating from the pulmonary artery, we report a case of sudden cardiac arrest during exercise. After successful cardiopulmonary resuscitation, the patient underwent echocardiography and selective coronary angiography, and the disease was firmly diagnosed. Consequently, a thoracic surgery was performed. During the operation, the left coronary artery was transplanted to the root of the aorta and the pulmonary valve and artery were reconstructed. Finally, the surgery was successful...

Since 1998 pulmonary hypertension has been clinically classified into five well-defined, distinct categories. A definitive diagnosis of pulmonary hypertension requires the invasive confirmation of an elevated mean pulmonary artery pressure of 25 mm Hg or above during a right heart catheterization. From a hemodynamic point of view, pulmonary hypertension is classified into precapillary and postcapillary pulmonary hypertension on the basis of a pulmonary artery wedge pressure threshold value of 15 mm Hg. Pulmonary vascular resistance is better characterized by multi-point pressure/flow measurements than by single-point determination...
