Abstract Background: In just a few years, cardiac resynchronization therapy (CRT) has emerged as a key player in the treatment of advanced heart failure (HF). However, approximately 30% of patients with CRT device implantation do not achieve a favorable response. The purpose of the present study was to identify clinical, electrocardiographic, and echocardiographic predictors of a positive response to biventricular pacing in patients with advanced decompensated HF. Methods: This prospective, observational study involved 42 consecutive patients admitted in emergency settings in our clinic with HF in New York Heart Association (NYHA) functional class III/IV, with QRS duration ≥120 ms and left ventricle ejection fraction (LVEF) ≤35%, who underwent cardiac resynchronization therapy (CRT-P or CRT-D) between January 2010 and July 2014. Statistical analysis was performed using IBM SPSS statistical software. Results: The clinical response (improvement in NYHA class) was recorded in 6 patients (14.3%), while echocardiographic response (change in ejection fraction and/or in endsystolic or end-diastolic volumes) was recorded in 10 patients (23.8%). The most frequently observed type of response to CRT was the double (clinical plus echocardiographic) response, recorded in 23 out of 42 patients (54.8%). ROC analysis identified the absence of chronic renal disease and the duration from onset of symptoms to CRT implantation as good predictors for clinical improvement after CRT (AUC = 0.625, 95% CI: 0.400–0.850 for absence of renal failure and AUC = 0.516, 95% CI: 0.369–0.853 for symptoms duration). However, gender, age, duration from symptom onset, and comorbidities were not good predictors for the echocardiographic response (AUC <0.600). Conclusions: CRT represents an important therapeutic option for selected patents with advanced decompensated HF and prolonged QRS interval; however, only some of the commonly used criteria can predict a favorable outcome in patients undergoing CRT.

Abstract Background  The safety and efficacy of MitraClip for advanced heart failure (HF) patients who are inotrope-dependent or mechanically supported are unknown. Case summary  The patient was a 71-year-old man diagnosed as dilated cardiomyopathy in 2003. He was admitted due to worsening HF in January 2019 and became dependent upon intravenous infusion of inotropes. During the 8-month hospitalization, his haemodynamics were relatively static with bed rest and continuous inotropes, but he was definitely dependent on them. Our multidisciplinary team decided to perform both cardiac resynchronization therapy (CRT) and MitraClip under Impella support. First, Impella was inserted from left subclavian artery. After a week, CRT was implanted from right subclavian vein, and the QRS duration of electrocardiogram became remarkably narrow. MitraClip was performed 2 weeks after Impella, and functional mitral regurgitation improved from severe to mild, and Impella was removed on the same day. Inotropes could be ceased, and he was discharged 2 months after MitraClip. Discussion  During inotrope-dependent status, there was a risk that HF would worsen with haemodynamic collapse when performing CRT implantation, and we firstly supported his haemodynamics by Impella. Cardiac resynchronization therapy implantation before MitraClip seemed to be crucial. In fact, the mitral valve morphology before Impella insertion had very poor coaptation of the anterior and posterior leaflets that was not optimal for MitraClip procedure. But the Impella support and correction of dyssynchrony by CRT markedly improved the coaptation of those leaflets. The combination therapy of CRT and MitraClip unloading with Impella maybe a new therapeutic option for advanced HF.

Abstract Background Advanced heart failure with reduced ejection fraction (HFrEF) is associated with poor prognosis. Cardiac resynchronization therapy (CRT) is an effective method of treatment for advanced HFrEF to reduce HF hospitalizations and mortality. Nonetheless, very long-term observation of HF patients undergoing CRT implantation is scarce. Aim To assess very long-term survival (≥10 years) and predictors of shorter survival (death within 10 years from CRT implantation). Methods We screened a large dataset of CRT population from a tertiary care university hospital comprising consecutive HF patients implanted with CRT from 2002 through 2019 to select those who were alive ≥10 years and those who died within 10 years since device implantation. We analyzed various patients' baseline, clinical and procedural characteristics and sought for predictors of mortality within 10 years from CRT implantation. Results Of 1059 CRT patients, 143 (13.5%) were alive ≥10 years since CRT implantation. On multivariable regression analysis the independent predictors for all-cause death up to 10 years from CRT implantation were as follows: age, HR 1.02, 95% CI 1.01–1.31; male sex, 1.27, 95% CI 1.01–1.60; primary prevention of sudden cardiac death (SCD), HR 0.72, 95% CI 0.58–0.89; ischemic cardiomyopathy, HR 1.41, 95% CI 1.76–1.70; NYHA class at implantation, HR 1.38, 95% CI 1.17–1.62; baseline left ventricle ejection fraction (EF), HR 0.97, 95% CI 0.96–0.98; severe mitral regurgitation, HR 1.38; 95% CI 1.08–1.75; baseline NT-proBNP concentration, HR 1.00, 95% CI 1.00–1.00; and creatinine level, HR 1.00, 95% CI 1.00–1.01. Conclusions In a real-life patient population with CRT only 13.5% survived over 10 years since device implantation. Independent predictors for death within 10 years since CRT implantation were older age, male sex, secondary prevention of SCD, ischemic and more advanced heart failure along with renal impairment.

Abstract Background Triple-Site versus Standard Cardiac Resynchronization Therapy Randomized Trial (TRUST CRT) was initiated in 2009 to verify the hypothesis whether triple-site (single right, double left) cardiac resynchronization therapy (CRT) may be superior to conventional, biventricular resynchronization in patients with advanced heart failure. Objectives To report 6-month outcomes and 10-year survival in TRUST CRT. Methods 100 consecutive patients with moderate to severe heart failure, ejection fraction of 35% or less, electrical and mechanical dyssynchrony, were randomly assigned in a 1:1 fashion to triple-site CRT defibrillator (TRIV) or to conventional CRT-D. The primary objective evaluated response-rate, defined as the 6-month's combined end point of alive status, freedom from hospitalization for heart failure or heart transplantation, relative≥10% increase in ejection fraction, ≥10% in peak oxygen consumption, and ≥10% in 6-minute walking distance. The secondary objective was to assess the occurrence of major adverse cardiovascular events (hospitalization for exacerbated heart failure requiring modification of pharmacotherapy, heart transplant or death) at month 6 and during remote observation. Results At month 6, the response-rate was higher in triple-site than conventional CRT-D group (51.1 vs. 26.5%, P=0.014). There were 2 deaths or heart failure events in the triple-site group (4%) as compared with 8 in the group assigned to conventional CRT-D (16%). A triple-site resynchronization resulted in 12% absolute risk reduction for secondary end point (hazard ratio 0.25; 95 percent confidence interval, 0.05 to 1.17, P=0.056, in comparison with the conventional CRT-D group). After 10 years of observation (median follow up of 7.1 years; range: 1.2–10.4) 57 patients (58.2%) died: 24 (53.3%) in the triple-site group, 31 (60.8%) in the conventional group (P=0.46) and 2 patients with and ICD (failed CRT implantation) [Figure]. Conclusions In patients with advanced heart failure, triple-site resynchronization combined with an ICD did not result in better survival than conventional resynchronization therapy in a median observation of 7.1 years.
