Patients with ventriculo-systemic discordance, a consequence of many congenital heart diseases, frequently develop systemic ventricular failure. This condition necessitates advanced heart failure treatment, heart transplantation, or mechanical assistance. One such congenital heart disease is situs inversus totalis. This condition is rare, but a disproportionate number of patients with this condition have complex congenital abnormalities. These abnormalities pose a set of unique surgical challenges, including those related to providing mechanical circulatory support. We report the placement of a HeartWare (HeartWare International Inc, Framingham, MA) continuous-flow ventricular assist device (VAD) in a patient with situs inversus totalis and congenitally corrected transposition of the great arteries (CCTGA). A 49-year-old man with CCTGA and situs inversus was admitted for worsening dyspnea. At age 13, he had undergone sub-pulmonic resection and surgical closure of atrial and ventricular septal defects. During the current admission, he developed cardiogenic shock and required intra-aortic balloon pump support. He was transferred to our institution for advanced heart failure treatment. The patient could not be weaned from the balloon pump. His creatinine level increased to 2.4 mg/dl, bilirubin increased to 3.2 mg/dl, aspartate aminotransferase was 65 IU/liter, and alanine aminotransferase was 100 IU/liter. On hospital Day 11, we implanted a HeartWare VAD in the right chest (Figure 1). The inlet cannula was inserted through the diaphragmatic surface of the right (systemic) ventricle, and the outflow aortic graft was anastomosed to the ascending aorta in the standard left–right plane. Post-operatively, the patient developed worsening inflammatory hepatopathy and acute kidney injury and required dialysis. However, his end-organ function subsequently recovered completely, and he was discharged on

Day 62 on anticoagulant therapy, a b-blocker, and sildenafil. He made regular follow-up visits to our outpatient clinic and was able to return to work.
Discussion Situs inversus totalis occurs in 1:8,500 births. The incidence of congenital heart disease is disproportionately high in individuals with this disorder relative to the general population. Atrioventricular and ventricular-systemic discordance are the most common abnormalities, but CCTGA also occurs. Itself a rare disorder, CCTGA constitutes approximately 1% of all congenital heart abnormalities. Among individuals with CCTGA and associated abnormalities, 67% develop congestive heart failure by age 45. Heart transplants have been performed in patients with situs inversus totalis, but the venous anastomosis is technically difficult and carries significant risk. Munoz-Guijosa et al1 reported a transplant in a patient with situs inversus totalis, TGA, and a previous Mustard procedure. We and others have reported VAD implantation in patients with CCTGA and in patients with dextrocardia.2,3 Faggian et al4 recently reported placing a HeartMate II VAD (Thoratec Corporation, Pleasanton, CA) in a patient with situs inversus totalis. Our patient with CCTGA and situs inversus totalis had complex anatomy that made heart transplantation technically difficult, so we chose to insert a continuous-flow pump to support the failing systemic ventricle. As continuous-flow pumps become smaller and more dependable, and as we learn more about the mechanical-physiologic interaction their use entails, they increasingly provide a needed therapeutic option in the growing population of adults with

A 57-year-old man with terminal usual interstitial pneumonia, treated by corticosteroids, was transferred to our intensive care unit after worsening respiratory distress that required tracheal intubation and mechanical ventilation. Rapidly, the patient underwent bilateral lung transplantation under extracorporeal membrane oxygenation. The transplant lung was ABO-compatible: the recipient’s blood group was Aþ and the donor was Oþ. Extracorporeal membrane oxygenation was weaned after 1 day and mechanical ventilation after 2 days. Post-operative induction immunosuppression was based on methylprednisolone, azathioprine, cyclosporine, and basiliximab. On Post-operative Day (POD) 10, intermittent hemodialysis was started due to anuric renal failure (urea, 311 mg/dl; creatinine, 2.6 mg/dl). On POD 11, the patient developed a hemolytic anemia (hemoglobin, 6.7 g/dl; lactate dehydrogenase, 4658 UI/l; bilirubin, 24.5 mg/dl; and haptoglobin, o 22 mg/dl; Figure 1). Because cyclosporinerelated microangiopathy was raised, cyclosporine was replaced by tacrolimus. However, this diagnosis was not confirmed because the schistocytes count was within the normal reference range (o 0.l%). Despite transfusions of Aþ red blood cells (RBCs), the anemia worsened secondary to an increase in hemolysis. Therefore, the passenger lymphocyte syndrome (PLS)
