Abstract
PURPOSE OF REVIEW This review provides an update on rheumatic mitral stenosis. Acute rheumatic fever (RF), the sequela of group A β-hemolytic streptococcal infection, is the major etiology for mitral stenosis (MS). RECENT FINDINGS While the incidence of acute RF in the Western world had substantially declined over the past five decades, this trend is reversing due to immigration from non-industrialized countries where rheumatic heart disease (RHD) is higher. Pre-procedural evaluation for treatment of MS using a multimodality approach with 2D and 3D transthoracic and transesophageal echo, stress echo, cardiac CT scanning, and cardiac MRI as well as hemodynamic assessment by cardiac catheterization is discussed. The current methods of percutaneous mitral balloon commissurotomy (PMBC) and surgery are also discussed. New data on long-term follow-up after PMBC is also presented. For severe rheumatic MS, medical therapy is ineffective and definitive therapy entails PMBC in patients with suitable morphological mitral valve (MV) characteristics, or surgery. As procedural outcomes depend heavily on appropriate case selection, definitive imaging and interpretation are crucial. It is also important to understand the indications as well as morphological MV characteristics to identify the appropriate treatment with PMBC or surgery.

Abstract
Even cardiac surgery has been accepted as the standard therapy for Lutembacher syndrome, a combination of congenital ostium secundum atrial septal defect (ASD) and acquired mitral valve stenosis (MVS), it also owns many limitations and disadvantages. Therefore, seeking for a less invasive therapy with the same efficacy may be worthwhile. Thanks to the development in technology and experience gaining in cardiovascular intervention, the combination of the two proved effective procedures, including percutaneous MVS treatment using balloon valvuloplasty and percutaneous ASD closure using atrial septal occluders, can be utilized as an attractive alternative therapy for these conditions. Here, we present a successful percutaneous intervention in Lutembacher syndrome using the combination of mitral balloon valvuloplasty and ASD device closure and thoroughly review the experience of using this combined procedure existing in the literature.

Abstract
MitraClip is an effective treatment method for severe mitral regurgitation in high-risk populations in terms of reducing morbidity and frequency of hospitalizations. Efficacy and safety of MitraClip device in elderly population have been established, yet there are only 2 case reports of MitraClip implantation in the younger patients, who generally tend to have less surgical risk (Gorenflo et al.; Joffe et al., 2016). We describe a 19-year-old patient with severe mitral regurgitation with prior mitral valve annuloplasty and received MitraClip implantation due to high-surgical risk.

Abstract
PURPOSE OF REVIEW The purpose of this review is to examine current evidence on the benefit of chronic total occlusion (CTO) revascularization in patients with ischemic cardiomyopathy and propose a systematic approach on how and when to accomplish revascularization in these patients. RECENT FINDINGS Coronary revascularization in patients with reduced ejection fraction (EF) is advocated for to improve left ventricular function and consequently clinical outcomes. Approximately 16-31% of angiograms in patients with advanced CAD are noted to have a concomitant coronary CTO. Its presence is a main predictor of worse outcomes. Over the past 15 years, advancements in interventional technologies and techniques have made it possible to treat CTO lesions percutaneously with success rates exceeding 90%. Different revascularization techniques have been organized into widely used algorithms for systematic CTO lesion crossing and treatment. Patients with reduced EF can be revascularized percutaneously with goal of complete functional revascularization. However, randomized prospective data is needed to justify the increased patient risks and healthcare costs associated with these procedures.

Abstract
INTRODUCTION A significant paravalvular leak (PVL) is estimated in at least 1-3% of patients undergoing surgical aortic and/or mitral valve replacement. Surgical repair of a PVL is associated with a 30-day mortality of approximately 10%. Percutaneous closure of PVL has emerged as an alternative to surgical repair. AIM We sought to examine the clinical outcomes of patients treated with percutaneous closure of PVL at an Irish tertiary referral centre. METHODS A prospective registry was used to record patient and procedural characteristics at the time of the PVL procedure. Medical records were retrospectively reviewed to assess clinical outcomes during the index hospitalisation and at follow-up. RESULTS A total of 26 PVL procedures were performed in 21 patients (mean age 68 ± 13 years, 76% male). Heart failure (HF), haemolysis (HL) or a combination of both was the presenting symptoms in 62%, 24% and 14% of patients, respectively. In the entire cohort, clinical success was achieved in 18 patients (86%). Clinical success was achieved more frequently when HF was the clinical indication compared to HL (100% versus 66%). Among patients presenting with isolated HF (n = 13), the mean NYHA class at baseline and follow-up was 2.5± 0.7 and 1.4± 0.7, respectively. Thirty-day mortality was 0%. There was one (3.8%) major adverse procedural complication (stroke). A total of six deaths (28%) occurred during follow-up (22 ± 13.4 months). CONCLUSIONS Patients with PVL represent a high-risk patient cohort. Percutaneous PVL offers a safe alternative to surgical PVL repair and appears particularly effective in those patients who present primarily with HF.

Abstract
The study describes our experience with Amplatzer Vascular Plugs (AVP2 and 4) and highlights a more refindes telescopic technique for AVP2 delivery. AVPs are well-established occlusion devices for vascular anomalies in congenital heart disease (CHD). The AVP2 is sometimes preferred to the AVP4 due to its shorter length, flat-profiled retention disks, and the availability of larger diameters, but its profile requires a larger inner lumen for safe delivery. The latter may actually hamper access to target lesions. This is a retrospective analysis of all CHD patients treated with the AVP2 and AVP4 between 12/2012 and 12/2015. Target vessels were characterized, measured, and the device-to-vessel diameter ratio calculated. A modified pigtail technique for AVP2 delivery was frequently used: a floppy wire was simply reinforced by the curved tip of a pigtail catheter (instead of the long sheath's dilator) to guide the required delivery sheath towards the desired landing zone. 59 patients with a median age and bodyweight of 3.0 years (range 0.1-75) and 13.8 kg (range 2.5-80) underwent the implantation of 106 plug-devices (30 AVP2, 76 AVP4) in 91 target vessels. Indications for their use were ductus arteriosus (19%), aortopulmonary (43%) as well as venovenous collaterals (34%) and other miscellaneous lesions (4%). The pigtail-supported AVP2 delivery in six patients proved very convenient. No complications occurred. AVPs are excellent devices for embolizing shunt vessels in CHD patients. Here, we describe a simplified telescoping technique for AVP2 delivery to enter curvy target lesions gently and efficiently.

Abstract
BACKGROUND Stenting of coarctation of the aorta (CoA) generally results in good angiographic results and a decrease in transcoarctation pressure gradient. However, effect on blood pressure control is less clear. The goal of the current retrospective analysis was to investigate the effects of CoA stenting on blood pressure control. METHODS A retrospective analysis was conducted in consecutive adult patients with a CoA who underwent a percutaneous intervention at one of the three participating hospitals. Measurements included office blood pressure, invasive peak-to-peak systolic pressure over the CoA, diameter of the intima lumen at the narrowest part of the CoA and use of medication. The follow-up data were obtained, based on the most recent examination date. RESULTS There were 26 native CoA and 17 recurrent CoAs (total n = 43). Seven of them underwent two procedures. Mean peak-to-peak gradient decreased from 27 mmHg to 3 mmHg (p < 0.001), and minimal diameter increased from a mean of 11 mm to 18 mm (p < 0.001). Mean systolic blood pressure decreased from 151 ± 18 mmHg to 135 ± 19 mmHg at first follow-up of 3.8 ± 1.9 months and 137 ± 22 mmHg at latest follow-up of 19.5 ± 10.9 months (p = 0.001 and p = 0.009, compared to baseline, respectively). The total number of hypertensive patients decreased from 74% to 27% at latest follow-up. No significant change in antihypertensive medication was observed. CONCLUSION A clinically significant decrease in systolic blood pressure of approximately 16 mmHg was shown after (re)intervention in CoA patients, which sustained at follow-up. This sustained decrease of blood pressure can be expected to lead to less future adverse cardiovascular events.

Abstract
Atrial septal device occluders such as amplatzer occluder have been designed to close atrial septal defects of paten formal ovale. Off label use of this device has been reported in pathological conditions that connect two vascular compartments with narrow neck. In this report, we describe a successful closure of a traumatically occurred AV fistula between iliac artery and iliac vein using amplatzer occluder device that has not been reported previously. This rare case is followed by a review of the literature.

Abstract
The use of balloon aortic valvuloplasty for congenital aortic valve stenosis was well established in literatures. However, balloon aortic valvuloplasty performed in low body weight neonates had been infrequently reported. Here we report a 5-day-old premature neonate diagnosed critical aortic valve stenosis. Balloon aortic valvuloplasty was performed as first-line therapy while the patient weighed only 1493 g. Balloon aortic valvuloplasty went successfully with transvalvular pressure gradient decreased from 80 mmHg to 44 mmHg. Aortic regurgitation after balloon aortic valvuloplasty was mild. The patient's clinical condition stabilized after balloon aortic valvuloplasty and was able to gain weight to 2665 g. Our report demonstrates that balloon aortic valvuloplasty is possible, safe and efficient as first-line approach for critical aortic valve stenosis in neonates with low body weight.

Abstract
A significant number of patients with high-risk pulmonary embolism have contraindications to thrombolytic therapy. Catheter-based therapy may be helpful and consists of a multitude of catheters and techniques, some old and some new. Although there are few data supporting the use of any of these techniques, there has been a recent rise in interest and use of catheter-based pulmonary embolectomy. This text describes the contemporary devices used in pulmonary embolism treatment, discusses their challenges, and proposes some future directions.

Abstract
Percutaneous hepatic interventions are generally safe given the fact that liver closely abuts the abdominal wall and hence it is easily accessible. However, the superior portion of liver, adjacent to the diaphragm, commonly referred as the “hepatic dome”, presents unique challenges for interventionists. Percutaneous access to the hepatic dome may be restricted by anatomical factors and special considerations may be required to avoid injury to the surrounding organs. The purpose of this review article is to discuss certain specific maneuvers and techniques that can enhance the success and safety of interventions in the hepatic dome.

Abstract
INTRODUCTION AND OBJECTIVES Paravalvular leak (PVL) is a possible complication after prosthetic valve implantation. PVL can cause significant symptoms of congestive heart failure and/or hemolysis. Medical therapy is palliative and reoperation has a high mortality rate. Percutaneous transcatheter closure is a promising alternative for symptomatic patients at high surgical risk. We aim to review the efficacy and safety of percutaneous PVL closure in a consecutive series of patients referred to our center. METHODS We performed a retrospective analysis of clinical and technical procedural data of patients referred to our center for percutaneous PVL closure between January 2009 and November 2015. RESULTS Twenty procedures were performed in 18 patients under general anesthesia and under transesophageal echocardiographic and radiographic guidance. Fourteen mitral PVLs were successfully treated in 13 patients and one aortic PVL in one patient. Most (eight) of the PVLs closed were in mitral bioprostheses. Two patients underwent a second intervention, which was technically successful in one. Technical success was achieved in 15 (75%) of the procedures. At discharge, median NYHA functional class decreased by one and hemolytic anemia decreased from seven cases (38.9%) to two (11.1%). Two patients had minor bleeding at the femoral vascular access site. Survival rates at six, 12 and 24 months were 77.8%, 77.8% and 61.1%, respectively. CONCLUSIONS In our experience, percutaneous PVL closure was overall effective and safe. The procedure is complex and a second intervention may be necessary. Percutaneous PVL closure may be a feasible alternative for selected symptomatic patients at high surgical risk refractory to medical therapy.

Abstract
A 39-year-old woman underwent uneventful percutaneous occlusion of an ostium secundum atrial septal defect (ASD) with a 22 mm Ultrasept ASD Occluder®. Transesophageal echocardiography (TEE) performed two years after implantation revealed a de novo residual left-to-right shunt through the correctly implanted device. Three-dimensional transesophageal echocardiography (3D TEE) further clarified this finding by showing a perforation of the device membrane coating. The patient underwent transcatheter closure of the residual shunt with a 20 mm Ultrasept PFO® device. The procedure was guided by fluoroscopy and real-time 3D TEE. At the end of the procedure 3D TEE documented correct device deployment with complete defect coverage and absence of residual shunt.

Abstract
With the increased use of intravascular catheters and devices, they have become the major non-malignant cause of superior vein cava (SVC) syndrome. We report a patient with liver cirrhosis who had received a peritoneovenous drainage catheter for refractory ascites, and then developed SVC syndrome because of concomitant occlusions of both the SVC and the drainage catheter. The patient regained patency of both the occluded vessel and the drainage catheter through percutaneous transluminal venoplasty, and there was dramatic improvement of clinical symptoms and good performance of the drainage catheter. Percutaneous intervention may be a feasible and effective therapy for SVC syndrome and intra-catheter thrombosis-related dysfunction.

Abstract
INTRODUCTION Although dual antiplatelet therapy (DAPT) is routinely given to patients after percutaneous coronary intervention (PCI) with stenting, the optimal duration is unknown. Recent evidence indicates there may be benefits in extending the duration beyond 12 months but such decisions may increase the risk of bleeding. Our objective is to provide a comprehensive overview of the literature for clinicians and policymakers via an umbrella review assessing the optimal duration of DAPT. METHODS AND ANALYSIS We will perform a comprehensive search of the published and grey literature for systematic reviews involving randomised controlled trials (RCTs) assessing the optimal duration of DAPT following PCI with stenting. The intervention of interest is extended DAPT (beyond 12 months) compared with short-term DAPT (6-12 months). Studies will be selected for inclusion by two reviewers, and the quality will be assessed. The primary outcomes of interest are all-cause mortality and cardiovascular mortality. Secondary outcomes will be bleeding (major, minor and gastrointestinal), urgent target vessel revascularisation, major adverse cardiovascular events, myocardial infarction, stroke and stent thrombosis. Outcomes will be assessed while on DAPT and after withdrawal of DAPT. Data will be summarised with respect to the number of included RCTs, number of participants, effect estimates and heterogeneity. Data will be reported separately based on patient demographics, procedural parameters (eg, stent types, lesion complexity and concurrent disease) and clinical presentation (eg, acute coronary syndromes, infarct type). ETHICS AND DISSEMINATION Our umbrella review aims to provide a comprehensive overview of the benefits and harms associated with extending DAPT beyond 12 months following PCI with stenting. The results of this review will inform clinical and policy decisions regarding the optimal treatment duration and reimbursement of DAPT following PCI with stenting. Results will be disseminated through a peer-reviewed publication and conference presentations. Ethics approval is not required for this study. TRIAL REGISTRATION NUMBER CRD42016047735.

Abstract
To evaluate the long-term cumulative incidence of ≥ moderate pulmonary regurgitation (PR) and re-intervention following balloon pulmonary valvuloplasty (BPV). While BPV for pulmonary valve stenosis (PS) relieves obstruction acutely, long-term outcomes are not well documented. Between 1982 and 2002, 211 patients had BPV for isolated PS. Follow-up data were available for 103 patients. Cumulative incidence of ≥ moderate PR and re-intervention was evaluated and risk factors for ≥ moderate PR assessed in univariate and multivariable analyses. Median age at BPV was 0.7 years (range 1 day-42.2 years); peak catheter gradient was 65 mmHg (range 31-169 mmHg); 23% had critical PS. Sixty-two patients had a recent echocardiogram with median follow-up 15.1 years (range 10.1-26.3 years); 60% had ≥ moderate PR. Three patients had pulmonary valve replacement following BPV due to symptomatic severe PR. In univariate analysis, critical PS, younger age, smaller BSA, and smaller pulmonary annulus at the time of BPV, as well as greater baseline PS gradient by catheterization, were associated with ≥ moderate PR (all p < 0.05). In multivariable analysis, only BSA < 0.3 m2 was independently associated with ≥ moderate PR (adjusted odds ratio 6.4, 95% confidence interval 1.2-33.6). In the largest study to date of > 10-year outcomes following BPV, 60% of patients with available follow-up data developed ≥ moderate PR. Few patients had pulmonary valve replacement. Patients with lower BSA at the time of BPV were more likely to have greater PR at late follow-up.

Abstract
The pathophysiology of diabetic cardiomyopathy (DC) is not fully understood. This frequently undiagnosed complication of chronic hyperglycemia leads to heart failure (HF). However, it is suggested that an appropriate metabolic control of diabetes at an early stage of this deleterious disease, is able to inhibit the development and progression of DC to HF. Recently, it has been postulated that myocardial ischaemia plays an important role in the development of this pathology. Results of the antianginal pharmacological treatment and revascularization are unsatisfactory and reveal a gap in our knowledge and current approaches to treating DC. Most recent studies emphasize the ischaemic component of DC as a key target for therapeutic strategies, which could change its unfavorable history. More stress is put on an early diagnosis of coronary artery disease (CAD), promoting prompt revascularization. Choosing the accurate time of surgical revascularization, with the inclusion of the metabolic background, can ensure complete revascularization with better prognosis. This review will focus on the complexity of DC and summarize contemporary knowledge of treatment strategies for patients with diabetes and CAD.

Drug-eluting stents appear superior to bare metal stents for vein-graft PCI in vessels up to a stent diameter of 4 mm. Heart Int 2016; 11:e17-e24. [PMID: 27924213 PMCID: PMC5072290 DOI: 10.5301/heartint.5000228] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/09/2016] [Indexed: 12/03/2022] Open
Abstract
Background Research trials have shown improved short-term outcome with drug-eluting stents (DES) over bare metal stents (BMS) in saphenous vein graft (SVG) percutaneous coronary intervention (PCI), primarily by reducing target vessel revascularization (TVR) for in-stent restenosis. We compared the outcomes in patients undergoing SVG stent implantation treated with DES or BMS. In exploratory analyses we investigated the influence of stent generation and diameter. Methods Data were obtained from a prospective database of 657 patients who underwent PCI for SVG lesions between 2003 and 2011. A total of 344 patients had PCI with BMS and 313 with DES. Propensity scores were developed based on 15 observed baseline covariates in a logistic regression model with stent type as the dependent variable. The nearest-neighbour-matching algorithm with Greedy 5-1 Digit Matching was used to produce two patient cohorts of 313 patients each. We assessed major adverse cardiac events (MACE) out to a median of 3.3 years (interquartile range: 2.1-4.1). MACE was defined as all-cause mortality, myocardial infarction (MI), TVR and stroke. Results There was a significant difference in MACE between the two groups in favour of DES (17.9% DES vs. 31.2% BMS group; p = 0.0017) over the 5-year follow-up period. MACE was driven by increased TVR in the BMS group. There was no difference in death, MI or stroke. Adjusted Cox analysis confirmed a decreased risk of MACE for DES compared with BMS 0.75 (95% confidence interval (CI) 0.52-0.94), with no difference in the hazard of all-cause mortality (hazard ratio: 1.08; 95% CI: 0.77-1.68). However, when looking at stent diameters greater than 4 mm, no difference was seen in MACE rates between BMS and DES. Conclusions Overall in our cohort of patients who had PCI for SVG disease, DES use resulted in lower MACE rates compared with BMS over a 5-year follow-up period; however, for stent diameters over 4 mm no difference in MACE rates was seen.

Abstract
PURPOSE Image-guided percutaneous pelvic procedures often play an important role in the management of women with gynecologic cancers. The purpose of this study is to evaluate the utilization of and indications for these procedures, and quantify their impact on patient management. METHODS IRB-approved retrospective record review of percutaneous pelvic procedures requested by gynecologic oncology, 2005 to 2015. Descriptive statistics and logistic regression were performed. RESULTS 392 pelvic procedures, including fluid aspiration, core biopsy, and fine needle aspiration, were performed in 225 women. Procedures were performed under sonographic guidance (303/392, 77.30%), CT guidance (87/392, 22.19%), or both (2/392, 0.51%). Pathology results included: no specimen sent (157/392, 40.05%), new cancer diagnosis (55/392, 14.03%), recurrence or metastasis of known primary cancer (107/392, 27.30%), benign tissue (67/392, 17.09%), and nondiagnostic (6/392, 1.53%). In terms of management, some procedures led to oncologic surgery, radiation, or chemotherapy (158/392, 40.31%), cessation of oncologic treatment (36/392, 9.18%), or treatment of infection (10/392, 2.55%). Many procedures were therapeutic (178/392, 45.41%), while a minority were performed for genomics (1/392, 0.26%) or did not impact clinical management (9/392, 2.30%). The number of procedures per year increased over time during the period of data collection. Date of service was a significant positive predictor of a purely therapeutic procedure (OR 1.69 [95 % CI 1.44-1.98], p < 0.0001) and a significant negative predictor of a malignant diagnosis (OR 0.72 [95 % CI 0.64-0.81], p < 0.0001), for each year later in the 10-year cycle. CONCLUSION In this single institution study, we identified a trend toward increased utilization of image-guided percutaneous pelvic interventions in women with gynecologic cancers. The case mix has shifted over the past 10 years, with procedures for symptom management constituting a larger proportion and diagnostic procedures constituting a smaller proportion of procedures over time.

Skirt followed by trouser stenting technique: True anatomical preservation of coronary Y-shaped bifurcation lesions while using "vanishing" bioresorbable scaffolds: A report of two cases. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2016; 18:281-286. [PMID: 27884628 DOI: 10.1016/j.carrev.2016.10.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Accepted: 10/14/2016] [Indexed: 11/25/2022]
Abstract
We report on two cases in which Y-shaped coronary bifurcations were treated with the use of Bioresorbable scaffolds. The first case was of a 50-year-old man with NSTEMI. Coronary angiography showed stenosis involving a Y-shaped bifurcation of proximal to mid LAD and diagonal. The lesion was wired using two 0.14 BMW guide wires, followed by serial pre-dilatation of LAD and Diagonal branch. The stent into proximal LAD was deployed first as a skirt (3.5 × 12 BVS). Stent was post-dilated. A second 2.5 × 28 BVS was deployed into diagonal branch, protruding backwards; along with a 2.0 × 15 SC balloon continuing into the mid LAD. Both balloons where pulled back proximally and re-inflated. The technique was repeated in reversed order for stenting the mid LAD using the third BVS (3.0 × 18 BVS). Finally two NC balloons where used to post-dilate both legs of the newly-formed trouser. The result was checked by OCT. The second case was that of a 62-year-old man with chest pain and NSTEMI. He had a history of previous PCI to LCx using bare metal stent. Coronary angiogram showed severe in-stent restenosis in mid LCX, extending into two large obtuse marginal branches. After wiring both OMs, serial pre-dilatation was done with two NC 2.5 × 20 balloons, followed by initial stenting of mid LCx inside old stent, as the proximal segment of bifurcation, using a 3.5 × 12 BVS, followed by implanting a 2.5 × 28 BVS into OM2 and 2.5 × 18 into OM1. At 6 months a clinical follow up via telephone contact revealed no recurrence of chest pain in both cases and no further intervention required.

Patients without ST elevation after return of spontaneous circulation may benefit from emergent percutaneous intervention: A systematic review and meta-analysis. Resuscitation 2016; 108:54-60. [PMID: 27640933 DOI: 10.1016/j.resuscitation.2016.09.004] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Revised: 08/30/2016] [Accepted: 09/05/2016] [Indexed: 10/21/2022]
Abstract
INTRODUCTION The American Heart Association recommends that post-arrest patients with evidence of ST elevation myocardial infarction (STEMI) on electrocardiogram (ECG) be emergently taken to the catheterization lab for percutaneous coronary intervention (PCI). However, recommendations regarding the utility of emergent PCI for patients without ST elevation are less specific. This review examined the literature on the utility of PCI in post-arrest patients without ST elevation compared to patients with STEMI. METHODS A systematic review of the English language literature was performed for all years to March 1, 2015 to examine the hypothesis that a percentage of post-cardiac arrest patients without ST elevation will benefit from emergent PCI as defined by evidence of an acute culprit coronary lesion. RESULTS Out of 1067 articles reviewed, 11 articles were identified that allowed for analysis of data to examine our study hypothesis. These studies show that patients presenting post cardiac arrest with STEMI are thirteen times more likely to be emergently taken to the catheterization lab than patients without STEMI; OR 13.8 (95% CI 4.9-39.0). Most importantly, the cumulative data show that when taken to the catheterization lab as much as 32.2% of patients without ST elevation had an acute culprit lesion requiring intervention, compared to 71.9% of patients with STEMI; OR 0.15 (95% CI 0.06-0.34). CONCLUSION The results of this systematic review demonstrate that nearly one third of patients who have been successfully resuscitated from cardiopulmonary arrest without ST elevation on ECG have an acute lesion that would benefit from emergent percutaneous coronary intervention.

Abstract
BACKGROUND The use of a balloon expandable stent valve includes balloon predilatation of the aortic stenosis before valve deployment. The aim of the study was to see whether or not balloon predilatation is necessary in transcatheter aortic valve replacement (TAVI). METHODS Sixty consecutive TAVI patients were randomized to the standard procedure or to a protocol where balloon predilatation was omitted. RESULTS There were no significant differences between the groups regarding early hemodynamic results or complication rates. CONCLUSIONS TAVI can be performed safely without balloon predilatation and with the same early results as achieved with the standard procedure including balloon predilatation. The reduction in the number of pacing periods required may be beneficial for the patient.

Invasive versus conservative strategy in acute coronary syndromes: The paradox in women's outcomes. Int J Cardiol 2016; 222:1110-1115.

Abstract
BACKGROUND We explored benefits and risks of an early invasive compared with a conservative strategy in women versus men after non-ST elevation acute coronary syndromes (NSTE-ACS) using the ISACS-TC database. METHODS From October 2010 to May 2014, 4145 patients were diagnosed as having a NSTE-ACS. We excluded 258 patients managed with coronary bypass surgery. Of the remaining 3887 patients, 1737 underwent PCI (26% women). The primary endpoint was the composite of 30-day mortality and severe left ventricular dysfunction defined as an ejection fraction <40% at discharge. RESULTS Women were older and more likely to exhibit more risk factors and Killip Class ≥2 at admission as compared with men. In patients who underwent PCI, peri-procedural myocardial injury was not different among sexes (3.1% vs. 3.2%). Women undergoing PCI experienced higher rates of the composite endpoint (8.9% vs. 4.9%, p=0.002) and 30-day mortality (4.4% vs. 2.0%, p=0.008) compared with men, whereas those who managed with only routine medical therapy (RMT) did not show any sex difference in outcomes. In multivariable analysis, female sex was associated with favorable outcomes (adjusted HR for the composite endpoint: 0.72, 95% CI: 0.58-0.91) in patients managed with RMT, but not in those undergoing PCI (adjusted HR: 0.96, 95% CI: 0.61-1.52). CONCLUSIONS We observed a more favorable outcome in women than men when patients were managed with RMT. Women and men undergoing PCI have similar outcomes. These data suggest caution in extrapolating the results from men to women in an overall population of patients in the context of different therapeutic strategies.

Abstract
Mitral regurgitation (MR) is the most common valvular heart disease in the Western world. The MR can be either organic (mainly degenerative in Western countries) or functional (secondary to left ventricular remodeling in the context of ischemic or idiopathic dilated cardiomyopathy). Degenerative and functional MR are completely different disease entities that pose specific decision-making problems and require different management. The natural history of severe degenerative MR is clearly unfavorable. However, timely and effective correction of degenerative MR is associated with a normalization of life expectancy. By contrast, the prognostic impact of the correction of functional MR is still debated and controversial. In this review, we discuss the optimal treatment of both degenerative and functional MR, taking into account current surgical and percutaneous options. In addition, since a clear understanding of the etiology and mechanisms of valvular dysfunction is important to guide the timing and choice of treatment, the role of the heart team and of echo imaging in the management of MR is addressed as well.
