We investigated the prevalence of intrapulmonary shunts in 82 patients with hepatic cirrhosis referred for echocardiography as part of liver transplantation evaluation. Intrapulmonary shunts were present in 49 of 82 patients (60%). Baseline characteristics were similar in patients with and without intrapulmonary shunts. Mean follow up was 41 +/- 15 months in patients with intrapulmonary shunts and 42 +/- 15 months in patients without intrapulmonary shunts (P not significant). At follow up, 8 of 49 patients (16%) with intrapulmonary shunts and 4 of 33 patients (12%) without intrapulmonary shunts had died (P not significant).

Background: Lung transplantation is a viable lifesaving option for patients with diffuse pulmonary arteriovenous malformations (AVMs). We present a case of diffuse pulmonary AVMs associated with juvenile polyposis and hereditary hemorrhagic telangiectasia (JP-HHT) that was successfully managed by lung transplantation.
Case Presentation: A 19-year-old woman developed severe hypoxemia due to pulmonary AVMs diagnosed at 4 years of age.

Introduction: Ischaemic stroke, primarily caused by thromboembolic events, typically arises as a consequence of underlying vascular or cardiac pathology. Non-thrombotic embolic strokes, although rare, are increasingly seen in interventional and intravascular procedures. Oxygen-ozone therapy (OOT) is one of the popular treatments for lumbar disc herniation, providing pain relief.

: The prevalence of portopulmonary hypertension (PoPH) is relatively low; however, its presence significantly worsens patients' prognosis. When diagnosed, PoPH can be effectively treated, and specific therapies can lead to a substantial reduction in pulmonary circulation pressure, facilitating the safe performance of liver transplantation. Echocardiography is recommended as a first-line method for the non-invasive diagnosis of pulmonary hypertension and serves as a valuable screening tool for patients being evaluated for liver transplantation (LT).

Pulmonary arteriovenous malformations (PAVMs) universally develop in patients with single ventricle congenital heart disease. Single ventricle PAVMs have been recognized for over 50 years but remain poorly understood. To improve our understanding, we developed a surgical rat model of Glenn circulation and characterized PAVM physiology over multiple time points.

Article Synopsis
- - Recent research has found that intrapulmonary bronchopulmonary anastomoses (IBAs) create common right-to-left shunts in the lungs and may significantly influence heart failure's pathophysiology.
- - The study involved 237 heart failure patients and assessed the relationship between mixed venous oxygen saturation (SvO₂) and various pulmonary pressures, finding that lower SvO₂ levels correlate with increased pulmonary artery systolic pressure (sPAP) and pulmonary artery wedge pressure (PAWP).
- - Results indicate that decreased SvO₂ is linked to increased sPAP and PAWP, likely due to IBAs, while left ventricular end-diastolic pressure (LVEDP) did not show a
