Thyrotoxicosis-facilitated bridge to recovery with a continuous-flow left ventricular assist device

Abstract: The HeartMate II is a continuous-flow left ventricular assist device that can be explanted from patients after cardiac recovery. We implanted a HeartMate II in a 21-year-old man who had idiopathic cardiomyopathy. A year later, he developed thyrotoxicosis, presumably secondary to amiodarone administered for ventricular fibrillation. Four months after the diagnosis of thyrotoxicosis, thyroid hormone levels had returned to normal, and native cardiac function had improved remarkably. After a support period of 24 m… Show more

“…Thus, patients treated with clenbuterol or medications targeting the neurohormonal system activation were shown to improve cardiac function and even undergo VAD explantation [1,2]. Along this line, a recent case report demonstrated a complete recovery in a young patient facilitated by increased thyroid hormone levels due to amiodarone use [3]. This may indicate a potential implication of thyroid hormone signalling in the pathophysiology of heart failure [4].…”

“…In fact, when T3 was administered in a series of 22 unstable (ischemic) heart donors (considered unsuitable for transplantation), 17 of those patients progressed to successful transplantation [72]. Here it should be noted that TH was shown to facilitate recovery in patients with end-stage heart failure and mechanical support devices [73]. …”

“…Προς το παρόν τα θετικά αποτελέσµατα της ΘΟ στην περίπτωση αυτή δεν έχουν αποδειχθεί 238 , πιθανότατα λόγω του γεγονότος ότι οι δότες ήταν σταθεροί, ελεύθεροι ισχαιµίας και ελάµβαναν Τ4 αντί για τη βιολογικά ενεργή Τ3. Την άποψη αυτή ενισχύει το γεγονός ότι όταν χορηγήθηκε Τ3 σε 22 ισχαιµικές καρδιές που είχαν κριθεί ακατάλληλες για µεταµόσχευση, οι 17 µετά τη χορήγηση µεταµοσχεύθηκαν µε επιτυχία239 .Σε αυτό το σηµείο θα πρέπει να παρατηρήσουµε πως ενδεχοµένως η χορήγηση Τ3 να βοηθά στην ανάκαµψη και τους ασθενείς µε τελικού σταδίου καρδιακή ανεπάρκεια αλλά και αυτούς που βρίσκονται σε µηχανική υποστήριξη192 .Από τα παραπάνω γίνεται σαφές πως είναι ανάγκη να διενεργηθούν µεγάλες κλινικές µελέτες που θα µελετήσουν τη δράση της ΘΟ µετά από ισχαιµία. Ήδη λαµβάνει χώρα µια τέτοια µελέτη (THIRST study) που διερευνά τη δράση της ΘΟ σε δόσεις υποκατάστασης σε ασθενείς µετά από ΟΕΜ240,241 .…”
