Noninvasive cardiac imaging is essential to provide objective evidence of reverse remodeling in heart failure patients treated with CRT, which correlates with patient prognosis.
Supports imaging to confirm reverse remodeling post-CRT; leaves open optimal protocols and integration into routine practice.
Cardiac resynchronization therapy (CRT) has become an alternative for patients with systolic dysfunction and persistence of heart failure symptoms despite optimal medical therapy. The role of noninvasive cardiac imaging before device implantation still remains controversial, but they are essential to provide an objective evidence of reverse remodeling of the heart which is, in turn, also related to the outcome of patients treated with CRT. The objective of this review is to highlight the acute and long-term CRT benefits as assessed by imaging, with special focus in cardiac reverse remodeling and its impact on prognosis.
