A 65-year-old male with lung cancer presents with JVD and hypotension; muffled heart tones are heard. Which life-saving procedure is indicated?

• A. Finger thoracostomy
• B. Needle decompression
• C. Pericardiocentesis
• D. REBOA

Answer: (C)

This situation shows cardiac tamponade from a pericardial effusion. When fluid accumulates around the heart, it compresses the chambers, especially during diastole, which reduces filling, lowers stroke volume, and drops blood pressure. JVD occurs because venous return is backed up, and muffled heart sounds come from the fluid surrounding the heart damping sound transmission. The immediate, life-saving move is to drain the pericardial space—pericardiocentesis—to relieve the pressure and allow the heart to fill normally again. In a patient with cancer, malignant pericardial effusion is a common cause of this picture, making prompt drainage essential. This approach directly addresses the tamponade, unlike procedures aimed at tension pneumothorax or noncompressible torso hemorrhage.
