ABSTRACT
BACKGROUND: The effectiveness of complete revascularization is well established in patients with ST-segment elevation myocardial infarction (STEMI), but it is less investigated in those with non-ST-segment elevation myocardial infarction (NSTEMI). OBJECTIVES: This study aimed to assess whether complete revascularization, compared with culprit-only revascularization, was associated with consistent outcomes in older patients with STEMI and NSTEMI. METHODS: In the FIRE (Functional Assessment in Elderly MI Patients with Multivessel Disease) trial, 1,445 older patients with myocardial infarction (MI) were randomized to culprit-only or physiology-guided complete revascularization, stratified by STEMI (n = 256 culprit-only vs n = 253 complete) and NSTEMI (n = 469 culprit-only vs n = 467 complete). The primary outcome comprised a composite of death, MI, stroke, or revascularization at 1 year. The key secondary outcome included a composite of cardiovascular death or MI at 1 year. RESULTS: In the overall study population, physiology-guided complete revascularization reduced both primary and key secondary outcomes. The primary outcome occurred in 54 (21.1%) STEMI patients randomized to culprit-only vs 41 (16.2%) STEMI patients of the complete group (HR: 0.75; 95% CI: 0.50-1.13) and in 98 (20.9%) NSTEMI patients randomized to culprit-only vs 72 (15.4%) NSTEMI patients of the complete group (HR: 0.71; 95% CI: 0.53-0.97), with negative interaction testing (P for interaction, 0.846). Similarly, no signal of heterogeneity with respect to the initial clinical presentation was observed for the key secondary endpoint (P for interaction, 0.654). CONCLUSIONS: Physiology-guided complete revascularization, compared with culprit-only revascularization, provided consistent benefit across the whole spectrum of patients with MI.

ABSTRACT
BACKGROUND: The FIRE trial (Functional Assessment in Elderly Myocardial Infarction Patients With Multivessel Disease) enrolled 1445 older (aged ≥75 years) patients with myocardial infarction and multivessel disease in Italy, Spain, and Poland. Patients were randomized to physiology-guided complete revascularization or treatment of the only culprit lesion. Physiology-guided complete revascularization significantly reduced ischemic adverse events at 1 year. This prespecified analysis investigated the changes between the 2 study groups in angina status, quality of life, physical performance, and frailty. METHODS: Patients underwent validated scales at hospital discharge (baseline) and 1 year later. Angina status was evaluated using the Seattle Angina Questionnaire, health-related quality of life by EQ visual analog scale, physical performance by short physical performance battery, and frailty by the clinical frailty scale. Mixed models for repeated measures analysis were used to study the association between the treatment arms, time, and scales. RESULTS: Baseline and 1-year Seattle Angina Questionnaire, EQ visual analog scale, short physical performance battery, and clinical frailty scale were collected in around two-thirds of the entire FIRE study population. The mean age was 80.9±4.6 years (female sex, 35.9%). Overall, 35.3% were admitted for ST-segment-elevation myocardial infarction, whereas the others were admitted for non-ST-segment-elevation myocardial infarction. Physiology-guided complete revascularization, compared with culprit-only revascularization, was associated with greater improvement in terms of angina status (Seattle Angina Questionnaire summary score, 7.3 [95% CI, 6.1-8.6] points), health-related quality of life (EQ visual analog scale, 6.2 [95% CI, 4.4-8.1] points), and physical performance (short physical performance battery, 1.1 [95% CI, 0.9-1.3] points). After 1 year, patients randomized to culprit-only revascularization experienced a deterioration in frailty status (clinical frailty scale, 0.2 [95% CI, 0.1-0.3] points), which was not observed in patients randomized to physiology-guided complete revascularization. CONCLUSIONS: The present analysis suggested that a physiology-guided complete revascularization is associated with consistent benefits in terms of angina status, quality of life, physical performance, and the absence of further deterioration of the frailty status.

BACKGROUND: Ehlers-Danlos syndrome (EDS) is a hereditary collagen vascular disorder characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Vascular EDS (vEDS) is a subtype of EDS which is characterized by vascular fragility. CASE PRESENTATION: This is a case report of a young man with vEDS hospitalized for myocardial infarction. He was presented with a coronary dissection and developed aortic dissection, coronary rupture, and cardiac tamponade until death. CONCLUSION: This case report highlights how patients with vEDS and acute coronary syndrome show a higher risk of vascular complications compared with other patients, and their admission to the institution with a cardiac surgery room could be helpful and safe for better management of the complications. Non-invasive methods could be useful to exclude other vascular diseases, before the emergency coronary intervention.
ABSTRACT
Background: Epicardial fat increase has not yet a clear correlation with coronary artery disease (CAD). Aim: This study had as goal to demonstrate a relationship between an increase of epicardial fat thickness (EFT) and CAD. Materials & methods: In this observational study, we included 234 patients who underwent invasive coronary angiography. Before invasive coronary angiography, all patients underwent echocardiographic-2D for evaluation of EFT and they were divided into groups based on Gensini score and also on Syntax score. Results: EFT was significantly correlated to the presence and severity of CAD assessed by Gensini score with a cut-off value of 5.2 mm (sensitivity of 90.9%-specificity of 87.3%- area under the ROC curve = 92.1%). Conclusion: EFT increase (fat index ≥5.2 mm) evaluated by echocardiographic-2D could be considered as a risk factor for predicting CAD.

Background Long-term data on durability of currently available transcatheter heart valves are sparse. We sought to assess the incidence of long-term (8-year) structural valve dysfunction and bioprosthetic valve failure in a cohort of patients with transcatheter aortic valve replacement ( TAVR ) who reached at least 5-year follow-up. Methods and Results Consecutive patients with at least 5-year follow-up available undergoing TAVR from June 4, 2007 to March 30, 2012 were included. Structural valve dysfunction and bioprosthetic valve failure were defined according to newly standardized European Association of Percutaneous Cardiovascular Interventions/ European Society of Cardiology/European Association for Cardio-Thoracic Surgery criteria and reported as cumulative incidence function to account for the competing risk of death. A total of 288 consecutive patients with a mean age of 80.7±5.3 years and with a mean Society of Thoracic Surgery mortality score of 8.1±5.1% were analyzed. Survival rate at 8 years was 29.8%. Mean pressure gradients decreased from 53.3±15.9 mm Hg (pre- TAVR ) to 10.5±4.5 mm Hg (in-hospital post- TAVR ) ( P<0.001). There was a small, not significant, increase in the transaortic gradient throughout follow-up. Bioprosthetic valve failure was observed in a total of 11 patients (8-year cumulative incidence function: 4.51%; 95% confidence interval , 1.95%-8.76%). Severe and moderate structural valve dysfunctions were reported in 7 patients (8-year cumulative incidence function: 2.39%; 95% confidence interval, 0.77%-5.71%) and 13 patients (8-year cumulative incidence function: 5.87%; 95% confidence interval , 3.06%-9.96%), respectively. Aortic valve reintervention (redo TAVR ) was successfully performed in 2 patients (0.7%) presenting with symptomatic severe restenosis and intraprosthetic regurgitation subsequent to endocarditis. Conclusions In an aged population of patients with symptomatic severe aortic stenosis treated with first-generation bioprostheses, TAVR was associated with a survival rate of 30% but low rates of bioprosthetic valve failure and structural valve dysfunction at 8 years.

BACKGROUND: We sought to describe an optimized approach to coronary artery disease (CAD) screening and management in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: When invasive coronary angiography showed CAD, the treatment strategy and completeness of revascularization was determined based on coronary anatomy. TAVR was performed in the same setting if percutaneous coronary intervention (PCI) was uncomplicated; otherwise TAVR was postponed. A total of 604 patients undergoing CAD screening at the time of TAVR procedure were prospectively included in this study. Severe CAD was found in 136 patients (22.5%). Among patients with severe CAD, 53 patients (8.8%) underwent uncomplicated PCI. After PCI, TAVR was postponed in 2 patients (0.3%). In 83 patients (13.8%), coronary angiography showed severe CAD that was left untreated. After TAVR, all-cause and cardiovascular 30-day mortality rates were 2.4% and 1.4%, respectively. Disabling stroke, myocardial infarction, and life-threatening bleeding occurred in 0.5%, 0.8%, and 4.0% of patients, respectively. Acute kidney injury II or III rate was 3.3%. At 2 years, all-cause mortality rate was 14.1%. Disabling stroke and myocardial infarction occurred in 2.5% and 1.8% of patients, respectively. Patients undergoing TAVR and PCI in the same session had similar rate of the composite of death, disabling stroke, and myocardial infarction when compared with patients without CAD, and patients with severe CAD left untreated (TAVR+PCI: 10.4%; severe CAD left untreated: 15.4%; no-CAD: 14.8%; P=0.765). CONCLUSIONS: In patients undergoing TAVR, screening of CAD with invasive coronary angiography and ad hoc PCI during TAVR is feasible and was not associated with increased periprocedural risks. PCI followed by TAVR in the same session had similar outcomes than TAVR in which PCI was not performed.

OBJECTIVE: The aim of this study was to conduct a weighted meta-analysis to determine the rates of acute (≤30days) major outcomes after (TAVR) with second-generation devices. METHODS: A comprehensive search of multiple electronic databases from January 2011 to May 2017 was conducted using predefined criteria. New-generation TAVR devices were defined as any device which received CE mark approval or is still under evaluation for CE marking after CoreValve and SAPIEN XT prostheses. RESULTS: A total of 37 studies including 10,822 patients met inclusion criteria and were included in the analysis. Devices investigated in the studies were the following: SAPIEN 3 (n=5423, 45.9%), Lotus Valve (n=3007, %), Portico (n=130, 1.1%), JenaValve (n=345, 2.9%), Symetis Acurate (n=1314, 11,1%), and Evolut R (n=1603, 13.6%). Thirty-day all-cause and cardiovascular 30-day death were 2.2% (95% CI: 1.6% to 2.8%) and 1.6% (95% CI: 0.9% to 2.3%), respectively; Any stroke and major/disabling stroke occurred at a pooled estimate rate of 2.6% (95% CI: 2.0% to 3.3%) and 0.9% (95% CI: 0.2% to 1.6%), respectively; life-threatening bleeding, 3.9% (95% CI: 2.9% to 5.0%); major vascular complications, 4.5% (95% CI: 3.7% to 5.4%); pacemaker implantation, 16.2% (95% CI: 12.7% to 19.6%); more than mild aortic regurgitation, 1.6% (95% CI: 0.9 to 2.3). CONCLUSIONS: Second-generation TAVR devices are associated with very low mortality and major complications rates at 30-day, and improved prosthesis performance with <2% of patients having more than mild post-procedural aortic regurgitation. On the other hand, the need for pacemaker implantation seems to remain an unresolved issue, and warrants further investigation.

BACKGROUND: Transcatheter aortic valves can degenerate in a manner similar to surgical bioprostheses. METHODS AND RESULTS: Clinical and echocardiographic outcomes of patients who underwent redo transcatheter aortic valve replacement (TAVR) procedures >2 weeks post procedure were collected from 14 centers. Among 13 876 patients, 50 (0.4%) underwent redo TAVR procedure at participating centers. Indications for redo TAVR were moderate-severe prosthetic aortic valve stenosis (n=10, 21.7%), moderate-severe central prosthetic aortic valve regurgitation (n=13, 28.3%), and moderate-severe paraprosthetic aortic valve regurgitation (n=25, 50.0%). The index TAVR was most commonly a Medtronic CoreValve (N=38, 76.0%), followed by Edwards SAPIEN-type valves (n=12, 24.0%) and Portico (n=1, 2.0%). The redo TAVR device was most commonly a CoreValve/Evolut R (n=29, 58.0%), followed by a SAPIEN-type valve (n=20,40.0%) or a Boston Lotus valve (n=1, 2.0%). In 40 patients (80.0%), redo TAVR was performed using the identical device type or that of the succeeding generation. Valve performance was uniformly good after redo TAVR (mean transvalvular gradient post redo TAVR: 12.5±6.1 mm Hg). At hospital discharge, all patients remained alive, with 1 nondisabling stroke (2.0%) and 1 life-threatening bleed (2.0%). Permanent pacemaker implantation was required in 3 out of 35 patients without a prior pacemaker (8.6%). Late survival was 85.1% at a median follow-up of 1589 days (range: 31-3775) after index TAVR and 635 days (range: 8-2460) after redo TAVR. CONCLUSIONS: Redo TAVR for the treatment of postprocedural and late occurrence of paravalvular regurgitation and transcatheter aortic valve prosthesis failure seems to be safe, and it is associated with favorable acute and midterm clinical and echocardiographic outcomes.

OBJECTIVES: The purpose of this study was to investigate the effect of the RenalGuard System (PLC Medical Systems, Milford, Massachusetts) on prevention of acute kidney injury (AKI) in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: TAVR is associated with varying degrees of post-procedural AKI. The RenalGuard System is a dedicated device designed for contrast-induced AKI prevention. Whether this device is also effective in patients with severe aortic stenosis undergoing TAVR is unexplored. METHODS: The present is an investigator-driven, single-center, prospective, open-label, registry-based randomized study that used the TAVR institutional registry of the Ferrarotto Hospital in Catania, Italy, as the platform for randomization, data collection, and follow-up assessment. A total of 112 consecutive patients undergoing TAVR were randomly assigned to hydration with normal saline solution controlled by the RenalGuard system and furosemide (RenalGuard group) or normal saline solution (control group). The primary endpoint was the incidence of Valve Academic Research Consortium-defined AKI in the first 72 h after the procedure. RESULTS: The AKI rate was lower in the RenalGuard group than in the control group (n = 3 [5.4%] vs. n =14 [25.0%], respectively, p = 0.014). The majority of patients (5.4% vs. 23.2%) developed a mild AKI (stage 1); severe damage (stage 3) occurred only in 1 patient in the control group (0.0% vs. 1.8%). No case of in-hospital renal failure requiring dialysis was reported. No significant differences in terms of mortality, cerebrovascular events, bleeding, and hospitalization for heart failure were noted in both groups at 30 days. CONCLUSIONS: Furosemide-induced diuresis with matched isotonic intravenous hydration using the RenalGuard system is an effective therapeutic tool to reduce the occurrence of AKI in patients undergoing TAVR.

OBJECTIVES: Primary graft failure (PGF) after heart transplantation is a detrimental complication, and carries high morbidity and mortality. The aim of this study was to analyze the results of our multidisciplinary approach in supporting patients affected with PGF after heart transplantation. METHODS: Out of 114 consecutive patients receiving orthotopic heart transplantation between January 2006 and July 2013, 18 (15.7%) developed PGF requiring veno-arterial extracorporeal membrane oxygenator (VA-ECMO) support. Fourteen patients were male and the mean age was 49±11 years. General principles in treating the patients were based on a low dose of adrenaline (0.05 mic/kg per min) infusion; femoral intra-aortic balloon pump (13 of the 18 patients); low dose of vasoconstrictors; careful fluid balance; daily echocardiographic transesophageal monitoring. RESULTS: Mean graft recipient pulmonary vascular resistance was 3.6±3.2 WU. Five patients had absolute contraindication to IABP placement. The mean left ventricle ejection fraction pre-VA-ECMO was 18.4%±10.2%. The mean VA-ECMO and IABP support times were 6.7±3.2 and 9.2±7.6 days, respectively. Mean VA-ECMO flow was 4164±679 l/min. The mean left ventricle ejection fraction increased to 43.4%±17.7% at the end of support. Weaning and discharge rates in patients treated with VA-ECMO+IABP were 84% and 53%, respectively. Causes of death were primarily end-stage organ failure. CONCLUSIONS: A multidisciplinary evaluation of ECMO patients done by intensivists, cardiologists, and surgeons may influence weaning and survival rate. Our approach seems to be a safe and reproducible strategy for avoiding left ventricle distension and fluid overload, and for detecting complications that negatively affect outcomes.
