Pulmonary Embolism Response Teams (PERT): Revolutionizing Multidisciplinary Care for PE Management

Pulmonary embolism (PE) represents a significant healthcare challenge, with complex presentations ranging from incidental findings to life-threatening cardiovascular collapse. The heterogeneous nature of PE, combined with rapidly evolving treatment options, creates a scenario where optimal management often requires input from multiple specialties. Recognizing this need, the concept of Pulmonary Embolism Response Teams (PERT) has emerged as an innovative care model designed to streamline evaluation and expedite treatment decisions through coordinated multidisciplinary collaboration.
