Session Information

Session Title: Systemic Sclerosis, Fibrosing Syndromes and Raynaud's - Clinical Aspects and Therapeutics: Systemic Sclerosis, Diagnostic and Therapeutic Aspects

Session Type: Abstract Submissions (ACR)

Background/Purpose: There is no specific treatment for primary cardiac involvement in SSc. Even if heart transplantation is an option, only 1 case have been reported1. The aim of the study was to collect data of patients with SSc and a primary cardiac involvement requiring a heart transplantation in order to establish the clinical course and expectable outcomes for this procedure.

Methods: Retrospective chart review of patients with SSc and a primary cardiac involvement requiring a heart graft in one of the major transplantation centers in France.

Results: A national survey allowed us to identify 6 patients fulfilling ACR/EULAR 2013 classification criteria for SSc. They had a history of primary cardiac involvement with an unequivocal indication for heart transplantation. 4/6 patients were women, 50% had lcSSc and 1 patient had an overlap with RA (Table 1). The median age at SSc diagnosis was 28 years and time to cardiac dysfunction diagnosis was 2.5 years. All patients had at least another systemic involvement, mostly gastrointestinal and/or musculoskeletal. Immunosuppressive treatment excluding corticosteroids has been prescribed to 3 patients.

In the year before transplantation, all patients were classified NYHA functional capacity III or IV and 5 of them required at least 1 hospitalisation. Median time from cardiac dysfunction diagnosis to transplantation was 4 years. The leading indication was heart failure requiring intravenous vasopressors except for 1 patient who was transplanted for recurrent ventricular arrhythmia. Cardiac pre-transplantation structural, functional and hemodynamic data are presented in Table 2.

The histopathology specimen of the explanted heart revealed myocardial fibrosis compatible with SSc primary cardiac involvement in all patients. Infectious complications occurred in 4 patients, 2 patients had ischemic lesions and 1 patient died from an unexplained graft failure. Median intensive care unit stay after the surgery was 22 days. During a median follow-up of 2.8 years, 4 patients had at least one acute cellular rejection, mainly of mild grade. Mild heart allograft vasculopathy occurred after a median of 2 years in 3 of 4 patients in whom coronary arteries were explored.

Conclusion: Symptomatic cardiac involvement in SSc has a bad prognosis. Heart transplantation is a relatively safe life-saving procedure in carefully chosen SSc patients with primary cardiac involvement manifesting with progressive dysfunction and/or arrhythmic complications.
