One significant way to drain fluid from the pericardial cavity is via an emergency pericardiocentesis. It is typically administered to patients suffering from extreme pericardial effusion, which can cause instability in their body’s blood flow. Pericardiocentesis, guided by ultrasound, is currently considered the gold standard for pericardial fluid aspiration. Traditionally, it relied on echocardiography using a low-frequency transducer, but the lack of real-time needle trajectory visualization sometimes led to complications. To address this, we are introducing a new technical approach in this brief review. We’ll be discussing an ultrasound-guided pericardiocentesis method that utilizes a highfrequency transducer, using an in-plane technique with a lateral-to-medial approach from the right parasternal. The suggested technique involves using a high-frequency ultrasound probe on the right parasternal region. This allows for immediate visualization of the needle path and neighboring anatomical structures like the myocardium, pericardial effusion, sternum and right internal thoracic vessels. The needle is inserted from lateral to medial at a 45-degree angle, ensuring a safe path to the pericardial effusion between the pleural sliding endpoint and the right internal thoracic vessels. The described method enables real-time visualization of the needle and its surroundings, potentially enhancing precision and preventing complications. It might ease access for both emergency pericardiocentesis and loculated pericardial effusion treatment surrounding the right atrium. Nonetheless, further research with significant patient populations is necessary.
