Abstract
Treatment for mixed valve disease has historically been limited, often surgery being the only option. With the recent advancement of transcatheter therapies, percutaneous approaches are quickly becoming viable therapeutic considerations in inoperable or high-risk patients, also offering the option for a staged or same-session treatment. Guidelines are primarily focused on single-valve disease. However, patients often present with multiple pathologies. This review summarizes the data and literature on transcatheter treatment of patients with mitral regurgitation who concomitantly have aortic stenosis or regurgitation, tricuspid regurgitation, or ischemic cardiomyopathy. Pathophysiology, hemodynamics, available therapies as well as order and timing of interventions are discussed.

Shortened Duration of Dual Antiplatelet Therapy Following Percutaneous Coronary Intervention: A Contemporary Clinical Review. Interv Cardiol 2023; 18:e31.

Abstract
Percutaneous coronary intervention with stent implantation is an integral aspect of minimally interventional cardiac procedures. The technology and techniques behind stent design and implantation have evolved rapidly over several decades. However, continued discourse remains around optimal peri- and post-interventional management with dual antiplatelet therapy to minimise both major cardiovascular or cerebrovascular events and iatrogenic bleeding risk. Standard guidelines around dual antiplatelet therapy historically recommended long-term dual antiplatelet therapy for 12 months (with consideration for >12 months in certain patients); however, emerging data and generational improvements in the safety of drug-eluting stents have ushered in a new era of short-term therapy to reduce the incidence of major bleeding events. This case review will provide an overview of the current state of guidelines around duration of dual antiplatelet therapy and examine recent updates and continued gaps in existing research.

Clin Res Cardiol 2021; 110:1993-2006. [PMID: 34505192 DOI: 10.1007/s00392-021-01935-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Accepted: 08/30/2021] [Indexed: 12/31/2022]
Abstract
BACKGROUND Bicuspid aortic valve may be associated with increased complications during transcatheter aortic valve implantation (TAVI). AIMS Compare balloon-expandable transcatheter heart valve (THV) safety and efficacy in severe tricuspid (TAV) and bicuspid (BAV) aortic stenosis. METHODS Transfemoral TAVI was performed in 743 patients (Jan 2014-June 2019) using the SAPIEN 3 THV. Aortic valve morphology was determined using computed tomography. Valve Academic Research Consortium-2 (VARC-2) derived safety and efficacy endpoints at 1 year were evaluated. RESULTS BAV patients (n = 78), were younger (77 [72, 81] vs. 81 [78, 85] years, p < 0.001) with lower surgical risk (EuroSCORE II 2.96% vs. 4.51% p < 0.001). Bicuspid valves were more calcified (BAV 1308mm3, TAV 848mm3 p < 0.001) with more asymmetric calcification (BAV 63/78 (81%), TAV 239/665 (36%), p < 0.001). Device success (BAV 94%, TAV 90%, p = 0.45) and major vascular complications (BAV 6%, TAV 9%, p = 0.66) were comparable. At 1 year, there was a trend toward lower combined all-cause mortality and rehospitalization for congestive heart failure in BAV patients (BAV 7%, TAV 13%, p = 0.08) with significantly lower all-cause mortality in this cohort (BAV 1%, TAV 9%, p = 0.020). VARC-2 time-related valve safety (BAV 22%, TAV 20%, p = 0.60) was comparable; however, bioprosthetic valve thrombosis remained more common in BAV patients (BAV 7%, TAV 2%, p = 0.010, Hazard ratio 3.57 [95% confidence interval 1.26, 10.10]). After propensity score matching, only bioprosthetic valve thrombosis remained significantly different. CONCLUSIONS Safety and efficacy of the SAPIEN 3 balloon-expandable THV in BAV is comparable with TAV. Higher rates of bioprosthetic valve thrombosis require further investigation.

Evaluation of a Low-Dose Radiation Protocol During Transcatheter Aortic Valve Implantation. Am J Cardiol 2021; 139:71-78. [PMID: 33190811 DOI: 10.1016/j.amjcard.2020.10.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 10/12/2020] [Accepted: 10/13/2020] [Indexed: 10/23/2022]
Abstract
We aimed to evaluate the efficacy and safety of a low-dose imaging protocol to reduce intraprocedural radiation during transcatheter aortic valve implantation (TAVI). Observational analysis: 802 transfemoral TAVI patients receiving balloon-expandable devices ≥23 mm at a high-volume centre. After propensity score matching, a standard-dose group (SD, n = 333) treated between January 2014 and February 2016 was compared with a low-dose group (LD, n = 333) treated between August 2017 and March 2019 after departmental uptake of a low-dose imaging protocol (reduced field size, high table height, use of "fluoro save," 3.75 frames/second acquisition, increased filtering). Primary end point was dose-area product (DAP). Secondary safety end points were VARC-2 device success and a composite of in-hospital complications. The LD protocol was associated with lower DAP (4.64 [2.93, 8.42] vs 22.73 [12.31, 34.58] Gy⋅cm2, p <0.001) and fluoroscopy time (10.4 [8.1, 13.9] vs 11.5 [9.1, 15.3] minutes, p = 0.001). Contrast use was higher in the LD group (LD 110 [94, 130] vs SD 100 [80, 135] milliliters, p = 0.042). Device success (LD 88.3% vs SD 91.3%, p = 0.25), and the composite end point (LD 8.1% vs SD 11.4%, p = 0.19) were similar. In multivariate analysis, the low-dose protocol was associated with a 19.8 Gy⋅cm2 reduction in procedural DAP (p <0.001). In conclusion, compared with standard imaging, a low-dose protocol for TAVI significantly reduced radiation dose without compromising outcomes.

Abstract
Background Clinical characteristics and outcomes of takotsubo syndrome (TTS) patients with malignancy have not been fully elucidated. This study sought to explore differences in clinical characteristics and to investigate short- and long-term outcomes in TTS patients with or without malignancy. Methods and Results TTS patients were enrolled from the International Takotsubo Registry. The TTS cohort was divided into patients with and without malignancy to investigate differences in clinical characteristics and to assess short- and long-term mortality. A subanalysis was performed comparing long-term mortality between a subset of TTS patients with or without malignancy and acute coronary syndrome (ACS) patients with or without malignancy. Malignancy was observed in 16.6% of 1604 TTS patients. Patients with malignancy were older and more likely to have physical triggers, but less likely to have emotional triggers compared with those without malignancy. Long-term mortality was higher in patients with malignancy (P<0.001), while short-term outcome was comparable (P=0.17). In a subanalysis, long-term mortality was comparable between TTS patients with malignancies and ACS patients with malignancies (P=0.13). Malignancy emerged as an independent predictor of long-term mortality. Conclusions A substantial number of TTS patients show an association with malignancy. History of malignancy might increase the risk for TTS, and therefore, appropriate screening for malignancy should be considered in these patients.

Abstract
Importance In patients with left main coronary artery (LMCA) stenosis, coronary artery bypass grafting (CABG) has been the standard therapy for several decades. However, some studies suggest that percutaneous coronary intervention (PCI) with drug-eluting stents may be an acceptable alternative. Objective To compare the long-term safety of PCI with drug-eluting stent vs CABG in patients with LMCA stenosis. Data Sources PubMed, Scopus, EMBASE, Web of Knowledge, and ScienceDirect databases were searched from December 18, 2001, to February 1, 2017. Inclusion criteria were randomized clinical trial, patients with LMCA stenosis, PCI vs CABG, exclusive use of drug-eluting stents, and clinical follow-up of 3 or more years. Data Extraction and Synthesis Trial-level hazard ratios (HRs) and 95% CIs were pooled by fixed-effect and random-effects models with inverse variance weighting. Time-to-event individual patient data for the primary end point were reconstructed. Sensitivity analyses according to drug-eluting stent generation and coronary artery disease complexity were performed. Main Outcomes and Measures The primary end point was a composite of all-cause death, myocardial infarction, or stroke at long-term follow-up. Secondary end points included repeat revascularization and a composite of all-cause death, myocardial infarction, stroke, or repeat revascularization at long-term follow-up. Results A total of 4 randomized clinical trials were pooled; 4394 patients were included in the analysis. Of these, 3371 (76.7%) were men; pooled mean age was 65.4 years. According to Grading of Recommendations, Assessment, Development and Evaluation, evidence quality with respect to the primary composite end point was high. Percutaneous coronary intervention and CABG were associated with a comparable risk of all-cause death, myocardial infarction, or stroke both by fixed-effect (HR, 1.06; 95% CI, 0.90-1.24; P = .48) and random-effects (HR, 1.06; 95% CI, 0.85-1.32; P = .60) analysis. Sensitivity analyses according to low to intermediate Synergy Between PCI With Taxus and Cardiac Surgery (SYNTAX) score (random-effects: HR, 1.02; 95% CI, 0.74-1.41; P = .89) and drug-eluting stent generation (first generation: HR, 0.90; 95% CI, 0.68-1.20; P = .49; second generation: HR, 1.19; 95% CI, 0.82-1.73; P = .36) were consistent. Kaplan-Meier curve reconstruction did not show significant variations over time between the techniques, with a 5-year incidence of all-cause death, myocardial infarction, or stroke of 18.3% (319 events) in patients treated with PCI and 16.9% (292 events) in patients treated with CABG. However, repeat revascularization after PCI was increased (HR, 1.70; 95% CI, 1.42-2.05; P < .001). Other individual secondary end points did not differ significantly between groups. Finally, pooled estimates of trials with LMCA stenosis tended overall to differ significantly from those of trials with multivessel coronary artery disease without left main LMCA stenosis. Conclusions and Relevance Percutaneous coronary intervention and CABG show comparable safety in patients with LMCA stenosis and low to intermediate-complexity coronary artery disease. However, repeat revascularization is more common after PCI.

Abstract
AIMS The present study aimed to determine the prognostic impact of resting heart rate (HR) and systolic blood pressure (SBP) in takotsubo syndrome (TTS). METHODS AND RESULTS Patients from the International Takotsubo Registry with complete data on HR and SBP were enrolled. We analysed all-cause mortality and major adverse cardiac and cerebrovascular events (MACCE) in tertiles of HR (<77 b.p.m., 77-94 b.p.m., >94 b.p.m.) and SBP (<119 mmHg, 119-140 mmHg, >140 mmHg). In addition, linear splines with interactions between HR and SBP were analysed. The risk of all-cause mortality was higher in the second HR tertile (1.89, 1.15-3.10; P = 0.012) and the third HR tertile (3.01, 1.90-4.79; P < 0.001) than in the first tertile. Similar effects were observed for MACCE. Low SBP was related to an increased risk of all-cause mortality (P < 0.001) and MACCE (P = 0.002). In a multivariable analysis of all-cause mortality, at HR >70 b.p.m., every 1 b.p.m. increase in HR was associated with a 1.7% increase (P < 0.001), and every 1 mmHg increase in SBP up to 130 mmHg was associated with a 2% risk reduction (P < 0.001). The risk of all-cause mortality thus was particularly elevated when low SBP occurred together with high HR. CONCLUSIONS High HR and low SBP are associated with an increased risk of all-cause mortality in TTS. HR reduction might be worthy of being investigated as a therapeutic strategy for this condition and high HR and low SBP can be used to evaluate risk in this acute presentation of TTS.

Abstract
Whilst the worldwide uptake of transcatheter aortic valve implantation (TAVI) over the last 10 years has been dramatic, iliac tortuosity remains a potential barrier to the most commonly chosen access route via the femoral artery. We describe the challenges posed by severe iliac tortuosity during transfemoral TAVI and contrast a difficult procedure - at the limit of the capability of current device delivery technology - with a straightforward implantation. The use of pre-procedural multi-detector computed tomography to assess the vasculature and a bilateral stiff wire technique for managing iliofemoral tortuosity are discussed.

Abstract
AIM To determine the potential clinical impact of OCT (Optical Coherence Tomography) during primary percutaneous coronary intervention in patients presenting with ACS (Acute Coronary Syndrome). METHODS AND RESULTS FORMIDABLE is a multicentre retrospective registry enrolling all patients presenting with ACS and treated with an OCT-guided approach, while the USZ registry enrolled patients treated with a standard angiography guided approach. Multivariate adjustment was performed via a propensity score matching. The number stents useds was the primary outcome, while the incidence of MACE (a composite of death, myocardial infarction, target vessel revascularization, and stent thrombosis) was the secondary endpoint. A total of 285 patients OCT-guided and 1,547 angiography guided patients were enrolled, resulting in 270 for each cohort after propensity score with matching. Two stents were used in 12% versus 34%; 3 stents in 8% versus 38% of the patients (P < 0.001). After a follow up of 700 days (450-890), there was no difference in myocardial infarction (6% vs. 6%, P = 0.86), while MACE (11% vs. 16%, P = 0.06), target vessel revascularization (2% vs. 4%, P = 0.15) and stent thrombosis rates (0% vs. 2.7%, P = 0.26) were numerically lower for the OCT-guided cohort but none of these endpoints did reach statistical significance. CONCLUSIONS An OCT-guided approach reduced the number of stents used, number of patients treated with more than one stent, while there was no statistically significant difference in clinical endpoints while most of them were numerically lower, including stent thrombosis rates. © 2016 Wiley Periodicals, Inc.

Impact of postdilatation on performance of bioresorbable vascular scaffolds in patients with acute coronary syndrome compared with everolimus-eluting stents: A propensity score-matched analysis from a multicenter "real-world" registry. Cardiol J 2016; 23:374-83.

Abstract
BACKGROUND Safety and efficacy of bioresorbable vascular scaffolds (BRS) and the role of postdilatation on outcome in acute coronary syndrome (ACS) patients compared with those of everolimus-eluting stents (EES) remain unknown. The aim of the study is to compare the safety and efficacy of BRS with EES in ACS and to investigate the role of BRS postdilatation. METHODS Consecutive ACS patients undergoing BRS implantation in 8 centers were com-pared with those with EES before and after propensity score matching. Major adverse cardiac event (MACE), myocardial infarction, and target lesion revascularization (TLR) were the primary endpoint. Sensitivity analysis was performed according to postdilatation after BRS implantation. We enrolled 303 BRS and 748 EES patients; 215 from each group were com-pared after matching, and 117 (55.2%) BRS patients were treated with postdilatation. RESULTS After a median follow-up of 24.0 months, MACE rates were higher in BRS patients than in EES patients (9.3% vs. 4.7%, p < 0.001), mainly driven by TLR (6.1% vs. 1.9%, p < 0.001). Stent thrombosis increased in the BRS group (2.8% vs. 0.9%, p = 0.01). How-ever, after sensitivity analysis, MACE rates in BRS patients with postdilatation were signifi-cantly lower than in those without, comparable to EES patients (6.0% vs. 12.6% vs. 4.7%, p < 0.001). The same trend was observed for TLR (3.4% vs. 8.4% vs. 1.9%, p < 0.001). Stent thrombosis rates were higher in both the BRS groups than in EES patients (2.6% vs. 3.2% vs. 0.9%, p = 0.045). CONCLUSIONS Postdilatation appears effective when using BRS in ACS patients. MACE rates are comparable to those of EES, although scaffold thrombosis is not negligible. Randomized prospective studies are required for further investigation.

Abstract
BACKGROUND ECG criteria differentiating Takotsubo cardiomyopathy (TTC) from mainly anterior myocardial infarction (MI) have been suggested; however, this was in small patient populations. METHODS AND RESULTS Twelve-lead admission ECGs of consecutive 200 TTC and 200 MI patients were compared in dichotomized groups based on the presence or absence of ST-elevation MI (STEMI versus STE-TTC and non-ST elevation MI versus non ST-elevation-TTC). When comparing STEMI and STE-TTC, ST-elevation in -aVR was characteristic of STE-TTC with a sensitivity/specificity of 43% and 95%, positive predictive value (PPV) 91%, and a negative predictive value (NPV) 62% (P<0.001); when ST-elevation in -aVR is accompanied by ST-elevation in inferior leads, sensitivity/specificity were 14% and 98% (PPV was 89% and NPV 52%) (P=0.001), and 12% and 100% when associated with ST-elevation in anteroseptal leads (PPV 100%, NPV 52%) (P<0.001). On the other hand, STEMI was characterized by ST-elevation in aVR (sensitivity/specificity of 31% and 95% P<0.001, PPV 85% and NPV 59%) and ST-depression in V2-V3-V4 (sensitivity/specificity of 24% and 100% P<0.001, PPV 100% and NPV 76%). When comparing non-ST elevation MI and non ST-elevation-TTC, T-inversion in leads I-aVL-V5-V6 had a sensitivity/specificity of 17% and 97% for non ST-elevation-TTC (PPV 83% and NPV 55%) (P<0.001), and ST-elevation in -aVR with T-inversion in any lead was also specific for non ST-elevation-TTC (sensitivity/specificity of 8% and 100%, PPV 100% and NPV 53%) (P=0.006). In non-ST elevation MI patients, the presence of ST-depression in V2-V3 was specific (sensitivity/specificity of 11% and 99%, PPV 91% and NPV 51%) (P=0.01). CONCLUSIONS ECG on admission can differentiate between TTC and acute MI, with high specificity and positive predictive value. CLINICAL TRIAL REGISTRATION URL: https://www.clinicaltrials.gov/.

Meta-Analysis of the Duration of Dual Antiplatelet Therapy in Patients Treated With Second-Generation Drug-Eluting Stents. Am J Cardiol 2016; 117:1714-23. [PMID: 27134057 DOI: 10.1016/j.amjcard.2016.03.005] [Citation(s) in RCA: 50] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2015] [Revised: 03/10/2016] [Accepted: 03/10/2016] [Indexed: 02/08/2023]
Abstract
The purpose of the study was to evaluate the optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention, especially in the era of second-generation drug-eluting stents (DES). The work was conducted from November 2014 to April 2015. All randomized controlled trials comparing short (<12 months) versus long (≥12 months) DAPT in patients treated with second-generation DES were analyzed. Sensitivity analyses were performed for length of DAPT and type of DES. All-cause death was the primary end point, whereas cardiovascular death, myocardial infarction (MI), stent thrombosis (ST), and major bleeding were secondary end points. Results were pooled and compared with random-effect models and meta-regression analysis. Eight randomized controlled trials with 18,810 randomized patients were included. The studies compared 3 versus 12 months of DAPT (2 trials), 6 versus 12 months (3 trials), 6 versus 24 months (1 trial), 12 versus 24 months (1 trial), and 12 versus 30 months (1 trial). Comparing short versus long DAPT, there were no significant differences in all-cause death (odds ratio [OR] 0.87; 95% confidence interval [CI] 0.66 to 1.44), cardiovascular death (OR 0.95; 95% CI 0.65 to 1.37), and ST (OR 1.20; 95% CI 0.79 to 1.83), and no differences were present when considering everolimus-eluting and fast-release zotarolimus-eluting stents separately. Shorter DAPT was inferior to longer DAPT in preventing MI (OR 1.35; 95% CI 1.03 to 1.77). Conversely, major bleeding was reduced by shorter DAPT (OR 0.60; 95% CI 0.42 to 0.96). Baseline features did not influence these results in meta-regression analysis. In conclusion, DAPT for ≤6 months is reasonable for patients treated with everolimus-eluting and fast-release zotarolimus-eluting stents, with the benefit of less major bleeding at the cost of increased MI, with similar survival and ST rates. An individualized patient approach to DAPT duration should take into account the competing risks of bleeding and ischemic complications after present-generation DES.

Abstract
The prevalence and factors related to hypertension (HTN) treatment and control are well investigated in the Western world but remain poorly understood in the Middle East and in middle-income countries such as Lebanon. In order to measure the prevalence, awareness, treatment, and control rates of HTN in Lebanon, the authors measured blood pressure (BP) in 1697 adults. The prevalence of optimal BP (<120/80 mm Hg) was 33% and that of pre-HTN (BP ≥120/80 mm Hg but <140/90 mm Hg) was 30%. The prevalence, awareness, treatment, and control (among treated hypertensive) rates of HTN were 36.9%, 53%, 48.9%, and 54.2%, respectively. Overall, only 27% of patients with HTN had their BP under control. Awareness was the most important predictor of treatment. No predictor of control could be identified. The authors concluded that HTN is prevalent in Lebanon and its overall control is low. Improving awareness is the most important target for intervention.
