Abstract/OtherAbstract:
INTRODUCTION: Pectus excavatum is commonly viewed as a benign condition. Associated alterations in hemodynamics are rare. We present an unusual case of right ventricular inflow obstruction and hemodynamic compromise as a consequence of pectus excavatum encountered during surgical intervention.
CASE: a 15-year-old male with pectus excavatum and thoracolumbar scoliosis developed severe hypotension after induction of general anesthesia and placement in the prone position for elective spinal fusion. A transesophageal echocardiogram revealed anterior compression of the right heart by the sternum with peak and mean right ventricular inflow gradients of 7 and 4 mm Hg, respectively. The gradient resolved with supine positioning and was reproduced with direct compression of the sternum.
CONCLUSIONS: Although pectus excavatum is generally a benign condition, the cardiologist should be aware of the potential for serious hemodynamic compromise related to positioning in these patients.
