Ventricular assist device implantation late after double switch operation for L-transposition of the great arteries

We provided a left ventricular assist device (LVAD) for a 22-year-old man with congenital L-transposition of the great arteries after anatomic repair at the age of 7 years. He was hospitalized for progressive low-output syndrome caused by intractable biventricular failure. He received LVAD in his morphologic left ventricle with a concomitant pulmonary valve replacement. After the surgery, critical multiorgan failure with severe right heart failure occurred. It took three postoperative months to normalize all organ function following improvement of morphologic right ventricular function. He has remained stable with LVAD support for 1.5 years.
