A practical approach to the diagnosis and initial management of acute right ventricular failure during pregnancy using point-of-care ultrasound.

Acute right ventricular failure is a critical condition in pregnancy that can lead to severe maternal and fetal complications. This expert review discusses the instrumental role of point-of-care ultrasound in diagnosing and managing ARVF in pregnant patients, highlighting its benefits for immediate clinical decision-making in obstetric emergencies. The unique physiological changes during pregnancy, such as increased blood volume and cardiac output, can exacerbate underlying or latent cardiac issues, making pregnant patients particularly susceptible to acute right ventricular failure. Common causes during pregnancy include pulmonary embolism, peripartum cardiomyopathy, and congenital heart diseases, each presenting distinct challenges in diagnosis and management. The real-time capability of point-of-care ultrasound allows for the immediate assessment of right ventricular size and function, evaluation of fluid status via the inferior vena cava, and identification of potential pulmonary embolism, offering a non-invasive, rapid, and dynamic diagnostic tool right at the bedside. The expert review details specific point-of-care ultrasound techniques adapted for pregnant patients, including the parasternal long and short axis and apical 4-chamber view, essential for evaluating right heart function and guiding acute management strategies. These include fluid management, adjustment of pharmacological treatment, and immediate interventions to support cardiac function and reduce ventricular overload. Point-of-care ultrasound enhances clinical outcomes by allowing clinicians to make informed decisions quickly, reducing the time to intervention, and tailoring management strategies to individual patient needs. However, despite its apparent advantages, the adoption of point-of-care ultrasound requires specialized training and familiarity with obstetric-specific protocols. This review advocates for the integration of point-of-care ultrasound into standard obstetric care protocols, emphasizing the need for clear guidelines and structured protocols that equip healthcare providers with the skills necessary to utilize this technology effectively. Future research should aim to refine these protocols and expand the evidence base to solidify the role of point-of-care ultrasound in improving maternal and fetal outcomes in acute right ventricular failure.
