Intravenous Diuresis in Severe Precapillary Pulmonary-Hypertension-Related Right Heart Failure: Effects on Renal Function and Blood Pressure.

In patients with right heart failure (RHF) and pulmonary hypertension (PH), classical teaching often advises cautious diuresis in the setting of 'preload dependence' to avoid renal injury and hemodynamic compromise. However, while this physiology may hold true in some clinical settings, such as acute ischemia with right ventricular infarction, it cannot necessarily be extended to PH-related RHF. Rather, in patients with precapillary PH and decompensated RHF, diuresis aimed to decongest the right heart and systemic venous system may be directly beneficial.

Right ventricular assessment in pulmonary hypertension.

Purpose Of Review: The purpose of this review is to provide an overview of assessment of right ventricular function in the context of pulmonary hypertension and pulmonary arterial hypertension (PAH). We will review unique features of right ventricular anatomy, delineation of cause of pulmonary hypertension through careful right ventricular assessment, echocardiographic and hemodynamic evaluation, and the importance of this assessment in prognosis.

Recent Findings: The importance of performance in prognosis and risk assessment in patients with pulmonary hypertension has been continually emphasized in ongoing research.

Modifiable Mechanical Ventilation Targets Are Associated With Improved Survival in Ventilated VA-ECLS Patients.

Background: In acute respiratory distress syndrome (ARDS), lung protective ventilation (LPV) improves patient outcomes by minimizing ventilator-induced lung injury. The value of LPV in ventilated patients with cardiogenic shock (CS) requiring venoarterial extracorporeal life support (VA-ECLS) is not known, but the extracorporeal circuit provides a unique opportunity to modify ventilatory parameters to improve outcomes.

Objectives: The authors hypothesized that CS patients on VA-ECLS who require mechanical ventilation (MV) may benefit from low intrapulmonary pressure ventilation (LPPV), which has the same end goals as LPV.

Aortic Mural Thrombus and Acute Coronary Syndrome in a Patient With Cannabinoid Hyperemesis Syndrome.

A 36-year-old woman with cannabinoid hyperemesis syndrome presented with chest pain and was found to have single-vessel coronary artery disease and an aortic mural thrombus. This case describes unique management with coronary artery bypass and surgical thrombectomy because of the patient's inability to tolerate uninterrupted antiplatelet therapy given her cannabinoid hyperemesis syndrome.
