Transesophageal echocardiographic evaluation of diastolic function.
Diastolic dysfunction is increasingly recognized as a cause of hemodynamic instability in the perioperative setting. Difficulty weaning from cardiopulmonary bypass and an increased need for inotropic support can occur in the absence of systolic impairment. Diastolic dysfunction can also impede hemodynamic stabilization and weaning progress in the mechanically ventilated critically ill patient. The use of transesophageal echocardiography in the ICU can assist in diagnosing the presence and progression of diastolic impairment, which may help to target therapeutic interventions that lead to positive outcomes. This review summarizes the conventional and new echocardiographic modalities for evaluating diastolic function in the perioperative setting.
