The IVC filter, IABP, and arrhythmia are key elements in the management of cardiovascular conditions. An IVC (Inferior Vena Cava) filter is a device implanted in the inferior vena cava to prevent blood clots from traveling to the lungs, thus reducing the risk of pulmonary embolism in patients with deep vein thrombosis or those unable to take anticoagulants. It is typically used in high-risk patients who cannot undergo traditional anticoagulant therapy.
