Abstract:
Transcatheter aortic valve replacement(TAVR)is the use of interventional catheter to transport the artificial heart valve to the aortic valve area through the patient's arterial,venous system or left ventricular apex,then release it to replace the original aortic valve to achieve normal physiological function.The"suicide left ventricle"phenomenon refers to the paradoxical hemodynamic collapse of dynamic left ventricular obstruction caused by left ventricular hypertrophy and hypersystole after the removal of the fixed valve obstruction of aortic stenosis after TAVR.The clinical manifestation is abnormal continuous hypotension that is ineffective to positive inotropic drugs during the operation or within a few hours after the operation.With the indications for transcatheter aortic valve surgery covering patients with low,medium and high risk of severe aortic stenosis,surgery-related complications have been reported to increase gradually."Suicide left ventricle"is worth studying and exploring as a fatal potential complication.This article mainly reviews four aspects of the overview of"suicide left ventricle",pathological mechanism,risk-related indicators,prevention strategies and treatment methods to be highly vigilant and make corresponding emergency plans for patients with aortic stenosis who may have suicide left ventricle risk,so as to minimize perioperative mortality.
