Treatment decisions must consider the appropriateness of the revascularization and the relative merits of PCI and CABG for different types of CAD. The guidelines recognize the increasing use of Fractional Flow Reserve (FFR) measurements to identify functionally more important lesions. Revascularization can be justified on either prognostic or symptomatic grounds (\u003Ca id=\u0022xref-table-wrap-3-1\u0022 class=\u0022xref-table\u0022 href=\u0022#T3\u0022\u003ETable 3\u003C\/a\u003E). Significant left main stenosis and significant proximal left anterior descending artery disease, especially in the presence of multivessel CAD, are strong indications for revascularization.

There is also a wealth of evidence from clinical trials showing that CRT improves quality-of-life, NYHA class, and performance on the 6-Minute Walk Test. CRT achieves its effects by optimizing atrioventricular (AV) delay and synchronizing the left and right ventricles. Optimized AV delay decreases mitral regurgitation, increases diastolic filling time, and improves LV dP\/dt while synchronization of the left and right ventricles improves interventricular synchrony, reduces paradoxical septal wall motion, improves LV regional wall motion, lowers end-systolic volumes, and improves LV dP\/dt\u003C\/p\u003E\n      \u003Cp id=\u0022p-23\u0022\u003EMohammad Shenasa, MD, O\u0027Connor Hospital, San Jose, California, USA, discussed the current Guidelines and Indications for CRT in patients with HF (\u003Ca id=\u0022xref-table-wrap-5-1\u0022 class=\u0022xref-table\u0022 href=\u0022#T5\u0022\u003ETable 5\u003C\/a\u003E) and reviewed the results of several trials evaluating CRT in HF.\u003C\/p\u003E\n      \u003Cdiv id=\u0022T5\u0022 class=\u0022table pos-float\u0022\u003E\n         \u003Cdiv class=\u0022table-inline\u0022\u003E\n            \u003Cdiv class=\u0022callout\u0022\u003E\n               \u003Cspan\u003EView this table:\u003C\/span\u003E\n               \u003Cul class=\u0022callout-links\u0022\u003E\u003Cli class=\u00220 first\u0022\u003E\u003Ca href=\u0022\/\u0022 class=\u0022table-expand-inline\u0022 data-table-url=\u0022\/highwire\/markup\/12518\/expansion?postprocessors=highwire_figures%2Chighwire_math%2Chighwire_inline_linked_media%2Chighwire_embed\u0026amp;table-expand-inline=1\u0022 html=\u00221\u0022 fragment=\u0022#\u0022 external=\u00221\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView inline\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00221\u0022\u003E\u003Ca href=\u0022\/highwire\/markup\/12518\/expansion?width=1000\u0026amp;height=500\u0026amp;iframe=true\u0026amp;postprocessors=highwire_figures%2Chighwire_math%2Chighwire_inline_linked_media\u0022 class=\u0022colorbox colorbox-load table-expand-popup\u0022 rel=\u0022gallery-fragment-tables\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView popup\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00222 last\u0022\u003E\u003Ca href=\u0022\/highwire\/powerpoint\/12518\u0022 class=\u0022highwire-figure-link highwire-figure-link-ppt\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload powerpoint\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\n            \u003C\/div\u003E\n         \u003C\/div\u003E\n         \u003Cdiv class=\u0022table-caption\u0022\u003E\n            \u003Cspan class=\u0022table-label\u0022\u003ETable 5.\u003C\/span\u003E \n            \u003Cp id=\u0022p-24\u0022 class=\u0022first-child\u0022\u003EACC\/AHC\/HRS Guidelines for Device-Based Therapy of Cardiac Rhythm Abnormalities.\u003C\/p\u003E\n         \u003Cdiv class=\u0022sb-div caption-clear\u0022\u003E\u003C\/div\u003E\u003C\/div\u003E\n      \u003C\/div\u003E\n      \u003Cp id=\u0022p-27\u0022\u003EAlthough the majority of the evidence for CRT in HF comes from studies in patients with NYHA class III or IV, HF several trials have examined the value of CRT alone or in combination with an implantable cardioverter-defibrillator (CRT-D) in patients with mild (class I or II; \u003Ca id=\u0022xref-table-wrap-5-2\u0022 class=\u0022xref-table\u0022 href=\u0022#T5\u0022\u003ETable 5\u003C\/a\u003E) HF.

The REVERSE study did not meet its primary endpoint (a composite response comparing the proportion of patients with worsened disease in the CRT-on vs CRT-off groups); however, among the subgroups of patients who improved, remained the same, or worsened, patients in the CRT-on group were significantly more likely to have improved over the course of 12 months (p\u0026lt;0.0001) [Linde C et al. \u003Cem\u003EJ Am Coll Cardiol\u003C\/em\u003E 2008].\u003C\/p\u003E\n      \u003Cp id=\u0022p-29\u0022\u003EIn the MADIT-CRT trial patients with ischemic or nonischemic cardiomyopathy, an ejection fraction of \u226430%, a QRS duration \u2265130 m\/sec, and NYHA class I or II symptoms were randomly assigned to receive CRT-D or an ICD alone. CRT-D decreased the risk of HF events. In addition, CRT was associated with a significant reduction in LV volumes and improvement in ejection fraction. These findings suggest that CRT may be used as an early management of heart failure with LV dysynchrony. However 12 patients need to be treated in order to save 1 heart failure patient.
