Cardiac Retransplantation: A Viable Option One, Two and Three Times | Patient Case Quiz

A 51-year-old male with familial dilated cardiomyopathy had his first heart transplant in 1990 and required a second heart transplant in 2003 because of graft vascular disease.

Since that the second transplant, follow-up was uneventful. Immunosuppression with triple therapy is established (cyclosporine A, mycophenolate mofetil, and steroids). Secondary to the calcineurin inhibitor treatment, he developed renal failure requiring a switch from cyclosporine to m-Tor inhibitors (baseline creatinine level 1.8 mg/dl and MDRD 42 mL/min/1.73 m2). In 2010, he had his first admission for heart failure (HF); suspecting cardiac rejection, a biopsy was performed confirming a Grade 1 acute rejection (Figures 1 and 2), which was treated conservatively (high-dose intravenous methylprednisolone).

In one of his follow-up echocardiograms a diffuse thickening of both ventricles was observed (Figure 3) with normal left ventricular ejection fraction and a dilated right ventricle with severely impaired function (TAPSE 4 mm). The filling pattern was restrictive with high filling pressures (E/E' 15). His New York Heart Association (NYHA) functional class declined to III-IV; he required several admissions between 2010 and 2012, and was treated with inotropic drugs and high-dose diuretics (Figure 4). Due to a lack of exact diagnosis, his physicians decided to perform a right catheterization (mPAP 34 mm Hg, PCWP 18 mmHg, CO 3.7 L/min, and PVR 4.4 Wood units) and repeat the biopsy ruling out rejection. The last blood test showed 9.2 g/dL Hb (29.6% Hto), stable renal function and high percentage of anti-human leucocyte antigen (HLA) antibodies (by luminex) (Figures 5 and 6).
