title: [Ventricular dysfunction and acute pulmonary edema related to intraoperative hypertensive crisis: a case report of clinical and echocardiographic assessment].
abstract: A 39-year-old obese woman underwent surgery to open an obstructed tear duct under general anesthesia. After reversal of the neuromuscular block, the patient had a sudden, severe increase in blood pressure related to nonsustained monomorphic ventricular tachycardia. Acute pulmonary edema and cardiogenic shock developed minutes after treatment with propranolol, labetalol, and nitroglycerin. Intraoperative transesophageal echocardiography showed severe diffuse left ventricular hypokinesis with an ejection fraction under 15%. Hemodynamic stability was achieved with inotropic infusions. Angiography ruled out coronary artery injury and echocardiographic follow-up revealed progressive improvement of ventricular function. We analyze diagnostic possibilities and describe the benefits of echocardiography in the diagnosis and treatment of intraoperative acute heart failure.
