Aortic root replacement in cardiac dextroversion.
Adult cardiac surgery in patients with malrotation of the heart is rare. A 60 year-old lady, with known cardiac dextroversion, presented with dyspnoea and pre-syncopal attacks. Echocardiographical and radiological investigation confirmed the dextroversion, with clockwise rotation of the heart through its longitudinal axis. This resulted in the right ventricular outflow tract and pulmonary artery being wrapped anteriorly around the aorta, with posterior displacement of the right atrium. The presence of a heavily calcified, bicuspid aortic valve and dilated ascending aorta was also demonstrated. At surgery, venous cannulation was established by rotating the heart anticlockwise and access to the aortic valve gained with a more superior oblique aortotomy. In the presence of a dilated ascending aorta with a calcified, bicuspid aortic valve, the aortic root was replaced with a valved conduit. To the authors' knowledge, this is the first report of an aortic root replacement in a patient with cardiac dextroversion.
