P224 PRIMITIVE DILATED CARDIOMYOPATHY IN YOUNG MAN NOT ELIGIBLE FOR CARDIAC TRANSPLANTATION: COMBINED USE OF DEFIBRILLATOR, CARDIAC CONTRACTILITY MODULATION (CCM) AND CARILLON

Abstract

Abstract Acute heart failure refers to rapid or gradual onset of symptoms and/or signs of chronic heart failure due to precipitating factors. Many patients with heart failure progress into a phase of advanced heart failure, characterized by persistent symptoms despite maximal therapy. Prognosis remains poor, with high 1–year mortality. Prognostic stratification is important to identify the ideal time for referral to an appropriate center capable of providing advanced therapies. We present the case of a 36–year–old black homeless man was admitted to Cardiological intensive care unit for acute heart failure complicated by intermediate–high risk bilateral subsegmentary pulmonary embolism, left endoventricular thrombosis, severe biventricular systolic dysfunction and secondary severe mitral insufficiency. After infusional diuretic and anticoagulant therapy, coronary angiography was performed documenting non–obstructive epicardial coronary arteries. Thereafter the therapy with sacubitril/Valsartan was falled, due to marked hypotension. Due to the high risk of sudden cardiac death, a single–chamber ICD was implanted in primary prevention. He was not eligible for long–term mechanical assistance (VAD) implantation and/or heart transplantation from referral centers, because of the patient‘s precarious psychosocial background. Furthermore, in the fullness of his faculties, the patient refused this possibility for religious reasons. Discharged in fair compensation, after resolution of pulmonary embolism and intracavitary thrombosis, he was again hospitalized for an exacerbation of chronic heart failure. Once labile hemodynamic compensation was reached, a cardiac contractility modulation device (CCM) was positioned, with the aim of improving symptoms. After optimization of therapy, with persistence of severe symptoms despite optimal medical and device therapy, options for intervention on the mitral valve were evaluated before further deterioration of the clinical conditions. Since this is a highly symptomatic patient at high risk for surgery, we opted for a coronary sinus mitral annuloplasty repair with Carillon, performed in the absence of complications. At the follow–up there was a mitral regurgitant volume reduction, improvement symptoms, in the absence of further hospitalizations.
