Single versus two-stent strategies for coronary bifurcation lesions: a systematic review and meta-analysis of randomized trials with long-term follow-up
Background:
The majority of coronary bifurcation lesions are treated with a provisional single‐stent strategy rather than an up‐front 2‐stent strategy. This approach is supported by multiple randomized controlled clinical trials with short‐ to medium‐term follow‐up; however, long‐term follow‐up data is evolving from many data sets.
Methods and Results:
Meta‐analysis of randomized controlled trials evaluating long‐term outcomes (≥1 year) according to treatment strategy for coronary bifurcation lesions. Nine randomized controlled trials with 3265 patients reported long‐term clinical outcomes at mean weighted follow‐up of 3.1±1.8 years. Provisional single stenting was associated with lower all‐cause mortality (2.94% versus 4.23%; risk ratio: 0.69; 95% confidence interval, 0.48–1.00; P=0.049; I2=0). There was no difference in major adverse cardiac events (15.8% versus 15.4%; P=0.79), myocardial infarction (4.8% versus 5.5%; P=0.51), target lesion revascularization (9.3% versus 7.6%; P=0.19), or stent thrombosis (1.8% versus 1.6%; P=0.28) between the groups. Prespecified sensitivity analysis of long‐term mortality at a mean of 4.7 years of follow‐up showed that the provisional single‐stent strategy was associated with reduced all‐cause mortality (3.9% versus 6.2%; risk ratio: 0.63; 95% confidence interval, 0.42–0.97; P=0.036; I2=0).
Conclusions:
Coronary bifurcation percutaneous coronary intervention using a provisional single‐stent strategy is associated with a reduction in all‐cause mortality at long‐term follow‐up
A case of an obstructive intramural haematoma during percutaneous coronary intervention successfully treated with intima microfenestrations utilising a cutting balloon inflation technique
During percutaneous coronary interventions (PCI), good lesion preparation with adequate balloon predilatation is a fundamental step before stent deployment in order to achieve optimal stent expansion and favourable long-term outcomes post PCI. During PCI, inadvertent vessel tearing can occur, resulting in coronary dissections and formation of intramural haematomas. The latter might be associated with compression of the vessel lumen and significant compromise of the coronary blood flow leading to myocardial ischaemia and infarction. Herein, we present a case of intramural haematoma that occurred after PCI of the left anterior descending artery resulting in occlusion of the vessel and the subsequent use of a cutting balloon inflation technique to resolve the haematoma and restore the normal coronary blood flow

Local versus general anesthesia for transcatheter aortic valve implantation (TAVR) – systematic review and meta-analysis
BACKGROUND: The hypothesis of this study was that local anesthesia with monitored anesthesia care (MAC) is not harmful in comparison to general anesthesia (GA) for patients undergoing Transcatheter Aortic Valve Implantation (TAVR). TAVR is a rapidly spreading treatment option for severe aortic valve stenosis. Traditionally, in most centers, this procedure is done under GA, but more recently procedures with MAC have been reported. METHODS: This is a systematic review and meta-analysis comparing MAC versus GA in patients undergoing transfemoral TAVR. Trials were identified through a literature search covering publications from 1 January 2005 through 31 January 2013. The main outcomes of interest of this literature meta-analysis were 30-day overall mortality, cardiac-/procedure-related mortality, stroke, myocardial infarction, sepsis, acute kidney injury, procedure time and duration of hospital stay. A random effects model was used to calculate the pooled relative risks (RR) with 95% confidence intervals. RESULTS: Seven observational studies and a total of 1,542 patients were included in this analysis. None of the studies were randomized. Compared to GA, MAC was associated with a shorter hospital stay (-3.0 days (-5.0 to -1.0); P = 0.004) and a shorter procedure time (MD -36.3 minutes (-58.0 to -15.0 minutes); P <0.001). Overall 30-day mortality was not significantly different between MAC and GA (RR 0.77 (0.38 to 1.56); P = 0.460), also cardiac- and procedure-related mortality was similar between both groups (RR 0.90 (0.34 to 2.39); P = 0.830). CONCLUSION: These data did not show a significant difference in short-term outcomes for MAC or GA in TAVR. MAC may be associated with reduced procedural time and shorter hospital stay. Now randomized trials are needed for further evaluation of MAC in the setting of TAVR
Percutaneous Closure of Paravalvular Leaks: A Systematic Review
[EN] Paravalvular leak (PVL) is an uncommon yet serious complication associated with the implantation of mechanical or
bioprosthetic surgical valves and more recently recognized with transcatheter aortic valves implantation (TAVI). A significant
number of patients will present with symptoms of congestive heart failure or haemolytic anaemia due to PVL and need further
surgical or percutaneous treatment. Until recently, surgery has been the only available therapy for the treatment of clinically
significant PVLs despite the significant morbidity and mortality associated with re-operation. Percutaneous treatment of PVLs
has emerged as a safe and less invasive alternative, with low complication rates and high technical and clinical success rates.
However, it is a complex procedure, which needs to be performed by an experienced team of interventional cardiologists and
echocardiographers. This review discusses the current understanding of PVLs, including the utility of imaging techniques in PVL
diagnosis and treatment, and the principles, outcomes and complications of transcatheter therapy of PVLs. (J Interven Cardiol

Procedural success and outcomes with increasing use of enabling strategies for chronic total occlusion intervention: an analysis of 28,050 cases from the British Cardiovascular Intervention Society database
BACKGROUNDEnabling strategies (ESs) are increasingly used during percutaneous coronary intervention for chronic total occlusive disease (CTO-PCI), enhancing procedural success. Using the British Cardiovascular Society dataset, we examined changes in the use of ESs and procedural/clinical outcomes for CTO-PCI. METHODS AND RESULTSESs were defined as intravascular ultrasound, rotational/laser atherectomy, dual arterial access, use of microcatheters, penetration catheters or CrossBoss, and procedures categorized by number of ESs used. Data were analysed on all elective CTO-PCI procedures performed in England and Wales between 2006 and 2014. Multivariable logistic regression was used to identify predictors of procedural success. During 28050 CTO-PCIs, there were significant temporal increases in ES use. There was a stepwise increase in CTO success with increased ES use, with 83.8% of cases successful where >= 3 ESs were used. Overall, CTO-PCI success rate for the whole cohort increased from 55.4% in 2006 to 66.9% in 2014 (P= 3 (P<0.001). After adjustment, although arterial complication, in-hospital bleeding, in-hospital mortality, and major adverse cardiovascular or cerebrovascular events remained more likely with ES use, 30-day mortality was not significantly different between groups. CONCLUSIONSES use during CTO-PCI was associated with significant improvements in CTO-PCI success. ES use was associated with increased procedural complications and in-hospital major adverse cardiovascular events, but not with 30-day mortality
Differences in patients and lesion and procedure characteristics depending on the age of the coronary chronic total occlusion
Introduction: Whether duration of chronic total occlusion (CTO) affects lesion and procedural characteristics remains largely unknown. Aim: To investigate whether CTO duration influences lesion characteristics and revascularization success. Material and methods: EuroCTO Registry data on patients who had CTO percutaneous coronary intervention between January 2015 and April 2017 were analyzed. Three groups were created based on occlusion age: 3 to 6 months (n = 1415), 7 to 12 months (n = 973), > 12 months (n = 1656). Results: Patients with greater CTO duration were older (63.0 (56.0–70.0); 63.0 (56.0–71.0); 66.0 (59.0–73.0) years respectively; p 20 mm (OR 1.77; 95% CI 1.49–2.10; p < 0.001), and collateral circulation Werner type 2 (OR = 1.20; 95% CI: 1.01–1.43; p = 0.041). The CTO duration was associated with lower procedural success (OR for success 0.60; 95% CI: 0.46–0.79; p < 0.001). In multivariate analysis in-hospital adverse events did not differ according to duration of CTO. Conclusions: Coronary artery CTO duration is associated with greater extent of calcification, lesion length, development of collateral circulation and, most importantly, with lower procedural success
