VILLARROEL-ABREGO, Hugo; NUNEZ, Elaine  y  GARILLO, Raúl. Terapia de resincronización cardíaca: un paciente con extrema disfunción ventricular y múltiples comorbilidades. Rev. costarric. cardiol [online]. 2018, vol.20, n.1, pp.42-48. ISSN 1409-4142.

We present the case of a 56-year-old man with non-compaction cardiomyopathy and very severe ventricular dysfunction, with intraventricular conduction disorder and wide QRS. He suffered from comorbidities including terminal diabetic nephropathy (on dialysis) and was never able to receive optimal medical therapy for hypotension and hyperkalemia. With indication IIa for cardiac resynchronization therapy, a resynchronizer with a defibrillator was implanted, with an acute clinical and excellent echocardiographic response. He died three months after the implant due to asystole that could not be rescued by the device. It is our opinion that the presence of severe comorbidities and the impossibility of giving optimal medical therapy are a limitation for the medium and long-term success of the resynchronization therapy.
