# Point-of-Care Ultrasound as a Key Diagnostic Tool in the Emergency Detection of Severe Pericardial Effusion

## TL;DR

This paper presents a case where point-of-care ultrasound quickly diagnosed a severe heart condition, improving patient care in an emergency.

## Contribution

The case demonstrates POCUS's critical role in detecting pericardial effusion and guiding urgent treatment.

## Key findings

- POCUS identified a large pericardial effusion with signs of cardiac tamponade.
- The patient was promptly referred for intensive care and pericardial drainage.
- POCUS significantly impacted clinical decision-making and patient outcomes.

## Abstract

Point-of-care ultrasound (POCUS) has become an essential extension of the physical examination in the emergency department, enabling rapid bedside assessment and timely clinical decision-making. We report a case of a 58-year-old female presenting with progressive dyspnea initially suggestive of a pulmonary etiology. Chest radiography revealed a right pleural effusion and apparent cardiomegaly. Bedside POCUS promptly identified a large circumferential pericardial effusion with echocardiographic signs of early cardiac tamponade, leading to immediate cardiology referral, intensive care admission, and pericardial drainage. This case highlights the pivotal role of POCUS in the early detection of life-threatening pericardial disease and its impact on clinical management and patient outcomes.
