A ruptured heart vessel can be saved, and the probability of successful resuscitation of a ruptured heart vessel is exceptionally high. Although dangerous, cardiac vascular rupture can usually recover on its own with effective treatment, such as pericardial puncture and drainage. The main cause of cardiac vascular rupture is extravasation of blood due to a guidewire, stent or balloon, which punctures a cardiac vessel during cardiac intervention. Most of the interventions can detect the rupture of a heart vessel, so the treatment is often timely. The common method is to first drain the pericardium by perforation to draw out the blood leaking into the pericardial cavity to avoid the formation of a heart pressure plug. Coagulation substances are also released at the ruptured vessel, or coagulants are injected.
