Impact of general anesthesia on the echocardiographic assessment of right ventricular function in pediatric patients with pulmonary arterial hypertension

Pulmonary artery wedge pressure is a crucial measurement for differentiating between hemodynamic categories of pulmonary hypertension (PH), particularly Groups 1 and 2. In this prospective study, we analyzed the diagnostic utility of checking wedge oxygen saturation to confirm wedge position during right heart catheterization in patients referred for PH.

Pulmonary endarterectomy (PEA) is a highly effective treatment for chronic thromboembolic pulmonary hypertension (CTEPH). However, persistent or recurrent pulmonary hypertension (persistent/recurrent PH) following surgery can adversely impact patients’ outcomes. 

In this PH Community Call we discussed: 

• Risk Assessment Models and Event-Free Survival in Pulmonary Arterial Hypertension
• PINK1/Parkin Deficiency Enhances Vascular Remodeling and Aggravates Hypoxia-induced Pulmonary Hypertension

Mechanical ventilation (MV), though life-saving in acute respiratory distress syndrome (ARDS), can cause ventilator-induced lung injury (VILI). MicroRNA-24 (miR-24) has been implicated in regulating inflammation and apoptosis, but its role in VILI remains unexplored.
