Aims: In severe myocardial dysfunction, extracorporeal life support (ECLS) can preserve organ perfusion. Occasionally, the high resulting afterload can lead to refractory pulmonary edema. We report our experience with percutaneous balloon atrioseptostomy used in this circumstance to discharge the left heart and prevent worsening pulmonary congestion.
Methods And Results: Between October 2002 and December 2009, 5 patients, with a mean age of 39 years, who were under peripheral ECLS underwent percutaneous balloon atrioseptostomy for refractory worsening pulmonary edema as determined by clinical, radiological, and echocardiographic criteria. Myocardial dysfunction was related to drug poisoning in 2 cases and to myocarditis in the 3 others. Atrioseptostomy successfully improved pulmonary edema and echocardiographic indices of left ventricular function in all cases. Four patients were eventually discharged. The fifth patient died in hospital due to multiorgan failure.
Conclusions: In our experience, percutaneous balloon atrioseptostomy appeared to be a rapid, effective, and minimally invasive technique for offloading the left heart of patients with a reversible cardiac dysfunction under ECLS and suffering from refractory pulmonary edema.

Background: Elevated intracranial pressure (ICP) is a potentially life-threatening condition requiring prompt intervention. While both mannitol and hypertonic saline (HTS) are commonly used hyperosmotic agents for treating elevated ICP, there is insufficient evidence comparing their renal safety profiles and overall effectiveness. This study protocol outlines a pragmatic randomized trial to compare protocol-based 11.

Objective: Genetically engineered porcine hearts may have an application for infants in need of a bridge to cardiac allotransplantation. The current animal model that resulted in 2 human applications has been validated in adult non-human primates only. We sought to create an infant animal model of life sustaining cardiac xenotransplantation to understand limitations specific to this age group.

Background: Dermal and pulmonary fibrosis are the main clinical symptoms of systemic scleroderma (SSc), for which there are no effective therapeutic agents. Tocilizumab is thought to improve the symptoms of fibrosis, but the effect of tocilizumab on dermal fibrosis has not been explored. This study aims to investigate the therapeutic effect of tocilizumab on skin fibrosis by inhibiting CD38 macrophages in the bleomycin-induced SSc mice model.

This study investigates the therapeutic effects of recombinant human IL-10 (rhIL-10) administered via aerosol inhalation in acute lung injury (ALI), with a particular focus on neutrophils. It explores how rhIL-10, in the presence of platelets, modulates neutrophil polarization to ameliorate acute lung injury. Initially, the ALI model established in mice demonstrated that aerosol inhalation of rhIL-10 significantly mitigated the cytokine storm in the lungs, reduced pulmonary edema, and alleviated histopathological damage to lung tissue.

Acute respiratory distress syndrome (ARDS) is defined as an acute inflammatory syndrome leading to increased pulmonary capillary leakage and subsequent interstitial and alveolar pulmonary edema. Hypoxia is the predominant symptom. The definition of ARDS comprises acute onset, bilateral patchy infiltration on chest X‑ray and a reduction of the ratio of arterial partial pressure of oxygen (PaO) to the fraction of inspired oxygen (FiO), which also determines the classification into mild (≤ 300), moderate (≤ 200) and severe (≤ 100) ARDS.
