Subxiphoid pericardial window in stable cardiac proximity injuries

Area of Science:

• Emergency Medicine
• Cardiovascular Surgery
• Diagnostic Imaging

Background:

• Cardiac proximity injuries require prompt and accurate diagnosis.
• Traditional diagnostic methods may have limitations in certain clinical settings.
• The subxiphoid pericardial window (SPW) offers a potential alternative for evaluating these injuries.

Purpose of the Study:

• To present a case series on the utility of the subxiphoid pericardial window (SPW) in stable patients with cardiac proximity injuries.
• To evaluate the diagnostic accuracy of SPW in this patient population.
• To review the literature supporting SPW as a diagnostic tool.

Main Methods:

• A retrospective case series of 11 stable patients with cardiac proximity injuries.
• Inclusion of patients who underwent subxiphoid pericardial window (SPW) procedure.
• Analysis of SPW results (positive/negative) and comparison with clinical outcomes.

Main Results:

• The study included 11 patients, with 4 positive and 7 negative SPW results.
• One false positive result was recorded.
• No false negatives were observed, indicating high sensitivity.
• Literature review suggests SPW is rapid and reliable for detecting occult cardiac injuries.

Conclusions:

• The subxiphoid pericardial window (SPW) is a rapid and reliable method for diagnosing cardiac proximity injuries in stable patients.
• SPW demonstrates high sensitivity with no false negatives in this series.
• This diagnostic approach is particularly advantageous in settings lacking immediate access to emergency echocardiography.
