Abstract
BACKGROUND Percutaneous coronary interventions in heavily calcified coronary lesions are associated with technical difficulties and the worse prognosis. Lesion preparation is important to reduce complications and improve outcomes. The aim of this study is to compare the results of rotational atherectomy (RA) and intravascular lithotripsy (IVL) at achieving optimal stent implantation using intravascular ultrasound criteria. METHODS Retrospective, single-center study comparing patients with heavily calcified coronary lesions that underwent percutaneous coronary interventions using RA or IVL. RESULTS IN TOTAL 25 patients (13 in the RA group and 12 in the IVL group) were included. Reference vessel diameter was similar between the groups [2.59 (2.51-3.63) mm in the RA group vs. 2.79 (2.59-3.16) mm in the IVL group; P = 0.89], as were minimal lumen area [1.02 (0.80-1.23) mm vs. 1.40 (1.01-1.40) mm; P = 0.43] and diameter stenosis [60.4% (52.3-72.3) vs. 56.1% (47.8-61.3); P = 0.56). The final minimal lumen area was significantly larger in the IVL group [7.6 mm2 (5.8-8.6) vs. 5.4 mm2 (4.5-6.2); P = 0.01] as were lumen area gain [4.1 mm2 (2.6-5.9) vs. 2.3 mm2 (1.4-3.6); P = 0.01] and final stent volume [491.2 mm3 (372.2-729.8) vs. 326.2 mm3 (257.1-435.4); P = 0.03]. In the RA group, 69.2% of the patients achieved the preestablished intravascular ultrasound-based criteria for successful stent implantation, vs. 100% of the patients in the IVL group (P = 0.04). CONCLUSION Patients in the IVL group achieved the Intravascular Ultrasound Versus Angiography-Guided Drug-Eluting Stent Implantation trial criteria of successful stent implantation more frequently than those treated with RA.

Abstract
BACKGROUND Drug-eluting stents (DESs) based on biodegradable polymers (BPs) have been introduced to reduce the risk for late and very late stent thrombosis (ST), which were frequently observed with earlier generations of DES designs based on durable polymers (DPs); however, randomized controlled trials on these DES designs are scarce. The meriT-V trial is a randomized, active-controlled, non-inferiority trial with a prospective, multicenter design that evaluated the 2-year efficacy of a novel third-generation, ultra-thin strut, BP-based BioMime sirolimus-eluting stent (SES) versus the DP-based XIENCE everolimus-eluting stent (EES) for the treatment of de novo lesions. METHODS The meriT-V is a randomized trial that enrolled 256 patients at 15 centers across Europe and Brazil. Here, we report the outcomes of the extended follow-up period of 2 years. The randomization of enrolled patients was in a 2:1 ratio; the enrolled patients received either the BioMime SES (n = 170) or the XIENCE EES (n = 86). The three-point major adverse cardiac event (MACE), defined as a composite of cardiac death, myocardial infarction (MI), or ischemia-driven target vessel revascularization (ID-TVR), was considered as the composite safety and efficacy endpoint. Ischemia-driven target lesion revascularization (ID-TLR) was evaluated as well as the frequency of definite/probable ST, based on the first Academic Research Consortium definitions. RESULTS The trial had a 2-year follow-up completion rate of 98.44% (n = 252/256 patients), and the clinical outcomes assessment showed a nonsignificant difference in the cumulative rate of three-point MACE between both arms (BioMime vs. XIENCE: 7.74% vs. 9.52%, P = 0.62). Even the MI incidences in the BioMime arm were insignificantly lower than those of the XIENCE arm (1.79% vs. 5.95%, P = 0.17). Late ST was observed in 1.19% cases of the XIENCE arm, while there were no such cases in the BioMime arm (P = 0.16). CONCLUSIONS The objective comparisons between the novel BP-based BioMime SES and the well-established DP-based XIENCE EES in this randomized controlled trial show acceptable outcomes of both the devices in the cardiac deaths, MI, ID-TVR, and ST. Moreover, since there were no incidences of cardiac death in the entire study sample over the course of 2 years, we contend that the findings of the study are highly significant for both these DES designs. In this preliminary comparative trial, the device safety of BioMime SES can be affirmed to be acceptable, considering the lower three-point MACE rate and absence of late ST in the BioMime arm over the 2-year period.

Abstract
BACKGROUND Mitral regurgitation (MR) is prevalent in patients undergoing transcatheter aortic valve implantation (TAVI). There are some controversies about the prognostic impact of MR in survival of TAVI patients. OBJECTIVE To examine the relationship between TAVI and MR in a patient population from the Brazilian TAVI Registry. METHODS Seven hundred and ninety-five patients from the Brazilian TAVI Registry were divided at baseline, discharge, and follow-up according to their MR grade as follows: absent/mild (AMMR) or moderate/severe (MSMR). They were subsequently regrouped according to their immediate and late changes in MR severity after TAVI as follows: no change, improved, or worsened MR. Predictors and prognostic impact on baseline as well as changes in MR severity were analyzed. Statistical significance was set at p < 0.05. RESULTS Baseline MSMR was present in 19.3% of patients and was a predictor of increased late mortality. Immediately after TAVI, 47.4 % of cases improved to AMMR, predicted by a higher Society of Thoracic Surgeons score and a higher grade of baseline aortic regurgitation. Upon follow-up, 9.2% of cases of AMMR worsened to MSMR, whereas 36.8% of cases of MSMR improved to AMMR. Lower baseline left ventricular ejection fraction (LVEF) and improvement in LVEF at follow-up were predictors of MR improvement. Progressive worsening of MR upon follow-up was an independent predictor of higher late mortality after TAVI (p = 0.005). CONCLUSIONS Baseline MSMR predicts late mortality after TAVI. Lower LVEF and improved LVEF at follow-up predict MR improvement after TAVI. Progressive worsening of MR severity at follow-up is an independent predictor of late mortality, which is a rare finding in the literature.

Abstract
OBJECTIVE The present study evaluated the effect of endovascular administration of calcium chloride to the carotid artery of swines, to create a model of arterial calcification. METHODS Fifteen Large White pigs were used for the study. Via endovascular treatment, carotid arteries were exposed during 9 min to either calcium chloride (experimental artery) or saline (control artery) with the use of the TAPAS catheter. Intravascular ultrasound (IVUS) imaging was obtained at baseline, postprocedure and at 30 days. Optical coherence tomography (OCT) imaging was obtained in vitro after carotids were harvested. Longitudinally cut parallel arterial segments were placed in a system of delicate clamps and underwent uniaxial strain test. All arteries underwent histopathological examination. RESULTS Calcium chloride treated segments showed extensive circumferential parietal calcification evident on both IVUS and OCT. Reduction in minimal lumen area on IVUS was evident in experimental arteries both at 24 hr and 30 days postprocedure. Histopathologic assessment (Von Kossa stain) confirmed medial calcification with mild intimal thickening. Biomechanical testing showed treated segments to have smaller breaking strength and less elastic deformation than controls. CONCLUSION We developed a nonexpensive, reproducible model of early carotid medial calcification in pigs. Our model has the potential to help the development of research to unravel mechanisms underlying arterial calcification, the use of current or new devices to treat calcified lesions as well as to serve as an option for training interventionalists on the use of such devices.

Abstract
Mitogen-activated kinase (MAPK) signalling pathways are involved in several important processes related to the development and virulence of Fusarium oxysporum. Reversible phosphorylation of the protein members of these pathways is a major regulator of essential biological processes. Among the phosphatases involved in dephosphorylation of MAPKs, type 2C protein phosphatases (PP2Cs) play important roles regulating many developmental strategies and stress responses in yeasts. Nevertheless, the PP2C family is poorly known in filamentous fungi. The F. oxysporum PP2C family includes seven proteins, but only Ptc1 has been studied so far. Here we show the involvement of Ptc6 in the stress response and virulence of F. oxysporum. Expression analysis revealed increased expression of ptc6 in response to cell wall and oxidative stresses. Additionally, targeted inactivation of ptc6 entailed enhanced susceptibility to cell wall stresses caused by Calcofluor White (CFW). We also demonstrate that the lack of Ptc6 deregulates both the Mpk1 phosphorylation induced by CFW and, more importantly, the Fmk1 dephosphorylation induced by pH acidification of the extracellular medium, indicating that Ptc6 is involved in the regulation of these MAPKs. Finally, we showed, for the first time, the involvement of a phosphatase in the invasive growth and virulence of F. oxysporum.

Abstract
BACKGROUND No data exist about the characteristics of infective endocarditis (IE) post-transcatheter aortic valve replacement (TAVR) according to transcatheter valve type. We aimed to determine the incidence, clinical characteristics, and outcomes of patients with IE post-TAVR treated with balloon-expandable valve (BEV) versus self-expanding valve (SEV) systems. METHODS Data from the multicenter Infectious Endocarditis After TAVR International Registry was used to compare IE patients with BEV versus SEV. RESULTS A total of 245 patients with IE post-TAVR were included (SEV, 47%; BEV, 53%). The timing between TAVR and IE was similar between groups (SEV, 5.5 [1.2-15] months versus BEV, 5.3 [1.7-11.4] months; P=0.89). Enterococcal IE was more frequent in the SEV group (36.5% versus 15.4%; P<0.01), and vegetation location differed according to valve type (stent frame, SEV, 18.6%; BEV, 6.9%; P=0.01; valve leaflet, SEV, 23.9%; BEV, 38.5%; P=0.01). BEV recipients had a higher rate of stroke/systemic embolism (20.0% versus 8.7%, adjusted OR: 2.46, 95% CI: 1.04-5.82, P=0.04). Surgical explant of the transcatheter valve (SEV, 8.7%; BEV, 13.8%; P=0.21), and in-hospital death at the time of IE episode (SEV, 35.6%; BEV, 37.7%; P=0.74) were similar between groups. After a mean follow-up of 13±12 months, 59.1% and 54.6% of the SEV and BEV recipients, respectively, had died (P=0.66). CONCLUSIONS The characteristics of IE post-TAVR, including microorganism type, vegetation location, and embolic complications but not early or late mortality, differed according to valve type. These results may help to guide the diagnosis and management of IE and inform future research studies in the field.

Abstract
The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, weak gravitational lensing, and galaxy clustering. Here we present combined results from these probes, deriving constraints on the equation of state, w, of dark energy and its energy density in the Universe. Independently of other experiments, such as those that measure the cosmic microwave background, the probes from this single photometric survey rule out a Universe with no dark energy, finding w=-0.80_{-0.11}^{+0.09}. The geometry is shown to be consistent with a spatially flat Universe, and we obtain a constraint on the baryon density of Ω_{b}=0.069_{-0.012}^{+0.009} that is independent of early Universe measurements. These results demonstrate the potential power of large multiprobe photometric surveys and pave the way for order of magnitude advances in our constraints on properties of dark energy and cosmology over the next decade.

Abstract
A new method based on the GC-MS analysis of thermolysis products obtained by treating bacterial samples at a high temperature (above 270°C) has been developed. This method, here named "In-Vial-Thermolysis" (IVT), allowed for the simultaneous determination of short-chain-length polyhydroxyalkanoates (scl-PHA) content and composition. The method was applied to both single strains and microbial mixed cultures (MMC) fed with different carbon sources. The IVT procedure provided similar analytical performances compared to previous Py-GC-MS and Py-GC-FID methods, suggesting a similar application for PHA quantitation in bacterial cells. Results from the IVT procedure and the traditional methanolysis method were compared; the correlation between the two datasets was fit for the purpose, giving a R2 of 0.975. In search of further simplification, the rationale of IVT was exploited for the development of a "field method" based on the titration of thermolyzed samples with sodium hydrogen carbonate to quantify PHA inside bacterial cells. The accuracy of the IVT method was fit for the purpose. These results lead to the possibility for the on-line measurement of PHA productivity. Moreover, they allow for the fast and inexpensive quantification/characterization of PHA for biotechnological process control, as well as investigation over various bacterial communities and/or feeding strategies.

Abstract
Background—
Transcatheter valve implantation inside failed bioprosthetic surgical valves (valve-in-valve [ViV]) may offer an advantage over reoperation. Supra-annular transcatheter valve position may be advantageous in achieving better hemodynamics after ViV. Our objective was to define targets for implantation that would improve hemodynamics after ViV.
Methods and Results—
Cases from the Valve-in-Valve International Data (VIVID) registry were analyzed using centralized core laboratory assessment blinded to clinical events. Multivariate analysis was performed to identify independent predictors of elevated postprocedural gradients (mean ≥20 mm Hg). Optimal implantation depths were defined by receiver operating characteristic curve. A total of 292 consecutive patients (age, 78.9±8.7 years; 60.3% male; 157 CoreValve Evolut and 135 Sapien XT) were evaluated. High implantation was associated with significantly lower rates of elevated gradients in comparison with low implantation (CoreValve Evolut, 15% versus 34.2%;
P
=0.03 and Sapien XT, 18.5% versus 43.5%;
P
=0.03, respectively). Optimal implantation depths were defined: CoreValve Evolut, 0 to 5 mm; Sapien XT, 0 to 2 mm (0–10% frame height); sensitivities, 91.3% and 88.5%, respectively. The strongest independent correlate for elevated gradients after ViV was device position (high: odds ratio, 0.22; confidence interval, 0.1–0.52;
P
=0.001), in addition to type of device used (CoreValve Evolut: odds ratio, 0.5; confidence interval, 0.28–0.88;
P
=0.02) and surgical valve mechanism of failure (stenosis/mixed baseline failure: odds ratio, 3.12; confidence interval, 1.51–6.45;
P
=0.002).
Conclusions—
High implantation inside failed bioprosthetic valves is a strong independent correlate of lower postprocedural gradients in both self- and balloon-expandable transcatheter valves. These clinical evaluations support specific implantation targets to optimize hemodynamics after ViV.

Abstract
BACKGROUND Patients with severe aortic stenosis have increased levels of prothrombotic and proinflammatory microparticles (MP), and MPs actively regulate pathological processes that lead to atherothrombotic cardiovascular events. Shear stress is a validated stimulus of MP production, and abnormal shear stress in aortic stenosis increases MP release in ex-vivo studies. We hypothesized that in patients with severe aortic stenosis, percutaneous replacement of the aortic valve (TAVR) would reduce abnormal shear stress and would decrease levels of circulating MPs. FINDINGS The experimental protocol utilized flow cytometry (FC) and nanoparticle tracking analysis (NTA) to quantify circulating plasma MP levels in aortic stenosis patients at baseline and 5 days after TAVR. The baseline and 5 day MP counts measured by FC were 6.10⋅10(5) ± 1.21⋅10(5) MP/μL and 5.74⋅10(5) ± 9.54⋅10(4) MP/μL, respectively (p = 0.91). The baseline and 5 day MP counts measured by NTA were 9.29⋅10(13) ± 1.66⋅10(13) MP/μL and 3.95⋅10(14) ± 3.11⋅10(14) MP/μL, respectively (p = 0.91). When MPs were stratified by cell source, there was no difference in pre/post TAVR endothelial, platelet, or leukocyte MP levels. CONCLUSION Levels of circulating MPs do not change acutely following TAVR therapy for aortic stenosis. Trial registered at clinicaltrials.gov NCT02193035 on July 11, 2014.

Abstract
Background Predicting mortality in patients undergoing transcatheter aortic valve
implantation (TAVI) remains a challenge. Objectives To evaluate the performance of 5 risk scores for cardiac surgery in predicting the
30-day mortality among patients of the Brazilian Registry of TAVI. Methods The Brazilian Multicenter Registry prospectively enrolled 418 patients undergoing
TAVI in 18 centers between 2008 and 2013. The 30-day mortality risk was calculated
using the following surgical scores: the logistic EuroSCORE I (ESI), EuroSCORE II
(ESII), Society of Thoracic Surgeons (STS) score, Ambler score (AS) and Guaragna
score (GS). The performance of the risk scores was evaluated in terms of their
calibration (Hosmer–Lemeshow test) and discrimination [area under the
receiver–operating characteristic curve (AUC)]. Results The mean age was 81.5 ± 7.7 years. The CoreValve (Medtronic) was used in 86.1% of
the cohort, and the transfemoral approach was used in 96.2%. The observed 30-day
mortality was 9.1%. The 30-day mortality predicted by the scores was as follows:
ESI, 20.2 ± 13.8%; ESII, 6.5 ± 13.8%; STS score, 14.7 ± 4.4%; AS, 7.0 ± 3.8%; GS,
17.3 ± 10.8%. Using AUC, none of the tested scores could accurately predict the
30-day mortality. AUC for the scores was as follows: 0.58 [95% confidence interval
(CI): 0.49 to 0.68, p = 0.09] for ESI; 0.54 (95% CI: 0.44 to 0.64, p = 0.42) for
ESII; 0.57 (95% CI: 0.47 to 0.67, p = 0.16) for AS; 0.48 (95% IC: 0.38 to 0.57, p
= 0.68) for STS score; and 0.52 (95% CI: 0.42 to 0.62, p = 0.64) for GS. The
Hosmer–Lemeshow test indicated acceptable calibration for all scores (p >
0.05). Conclusions In this real world Brazilian registry, the surgical risk scores were inaccurate in
predicting mortality after TAVI. Risk models specifically developed for TAVI are
required.

Abstract
BACKGROUND Semi-quantitative stenosis assessment by coronary CT angiography only modestly predicts stress-induced myocardial perfusion abnormalities. The performance of quantitative CT angiography (QCTA) for identifying patients with myocardial perfusion defects remains unclear. METHODS CorE-64 is a multicenter, international study to assess the accuracy of 64-slice QCTA for detecting ≥50% coronary arterial stenoses by quantitative coronary angiography (QCA). Patients referred for cardiac catheterization with suspected or known coronary artery disease were enrolled. Area under the receiver-operating-characteristic curve (AUC) was used to evaluate the diagnostic accuracy of the most severe coronary artery stenosis in a subset of 63 patients assessed by QCTA and QCA for detecting myocardial perfusion abnormalities on exercise or pharmacologic stress SPECT. RESULTS Diagnostic accuracy of QCTA for identifying patients with myocardial perfusion abnormalities by SPECT revealed an AUC of 0.71, compared to 0.72 by QCA (P = .75). AUC did not improve after excluding studies with fixed myocardial perfusion abnormalities and total coronary arterial occlusions. Optimal stenosis threshold for QCTA was 43% yielding a sensitivity of 0.81 and specificity of 0.50, respectively, compared to 0.75 and 0.69 by QCA at a threshold of 59%. Sensitivity and specificity of QCTA to identify patients with both obstructive lesions and myocardial perfusion defects were 0.94 and 0.77, respectively. CONCLUSIONS Coronary artery stenosis assessment by QCTA or QCA only modestly predicts the presence and the absence of myocardial perfusion abnormalities by SPECT. Confounding variables affecting the relationship between coronary anatomy and myocardial perfusion likely account for some of the observed discrepancies between coronary angiography and SPECT results.

Abstract
BACKGROUND Although the release of cardiac biomarkers after percutaneous (PCI) or surgical revascularization (CABG) is common, its prognostic significance is not known. Questions remain about the mechanisms and degree of correlation between the release, the volume of myocardial tissue loss, and the long-term significance. Delayed-enhancement of cardiac magnetic resonance (CMR) consistently quantifies areas of irreversible myocardial injury. To investigate the quantitative relationship between irreversible injury and cardiac biomarkers, we will evaluate the extent of irreversible injury in patients undergoing PCI and CABG and relate it to postprocedural modifications in cardiac biomarkers and long-term prognosis. METHODS/DESIGN The study will include 150 patients with multivessel coronary artery disease (CAD) with left ventricle ejection fraction (LVEF) and a formal indication for CABG; 50 patients will undergo CABG with cardiopulmonary bypass (CPB); 50 patients with the same arterial and ventricular condition indicated for myocardial revascularization will undergo CABG without CPB; and another 50 patients with CAD and preserved ventricular function will undergo PCI using stents. All patients will undergo CMR before and after surgery or PCI. We will also evaluate the release of cardiac markers of necrosis immediately before and after each procedure. Primary outcome considered is overall death in a 5-year follow-up. Secondary outcomes are levels of CK-MB isoenzyme and I-Troponin in association with presence of myocardial fibrosis and systolic left ventricle dysfunction assessed by CMR. DISCUSSION The MASS-V Trial aims to establish reliable values for parameters of enzyme markers of myocardial necrosis in the absence of manifest myocardial infarction after mechanical interventions. The establishments of these indices have diagnostic value and clinical prognosis and therefore require relevant and different therapeutic measures. In daily practice, the inappropriate use of these necrosis markers has led to misdiagnosis and therefore wrong treatment. The appearance of a more sensitive tool such as CMR provides an unprecedented diagnostic accuracy of myocardial damage when correlated with necrosis enzyme markers. We aim to correlate laboratory data with imaging, thereby establishing more refined data on the presence or absence of irreversible myocardial injury after the procedure, either percutaneous or surgical, and this, with or without the use of cardiopulmonary bypass.

Abstract
Background The MASS IV-DM Trial is a large project from a single institution, the Heart Institute (InCor), University of São Paulo Medical School, Brazil to study ventricular function and coronary arteries in patients with type 2 diabetes mellitus. Methods/Design The study will enroll 600 patients with type 2 diabetes who have angiographically normal ventricular function and coronary arteries. The goal of the MASS IV-DM Trial is to achieve a long-term evaluation of the development of coronary atherosclerosis by using angiograms and coronary-artery calcium scan by electron-beam computed tomography at baseline and after 5 years of follow-up. In addition, the incidence of major cardiovascular events, the dysfunction of various organs involved in this disease, particularly microalbuminuria and renal function, will be analyzed through clinical evaluation. In addition, an effort will be made to investigate in depth the presence of major cardiovascular risk factors, especially the biochemical profile, metabolic syndrome inflammatory activity, oxidative stress, endothelial function, prothrombotic factors, and profibrinolytic and platelet activity. An evaluation will be made of the polymorphism as a determinant of disease and its possible role in the genesis of micro- and macrovascular damage. Discussion The MASS IV-DM trial is designed to include diabetic patients with clinically suspected myocardial ischemia in whom conventional angiography shows angiographically normal coronary arteries. The result of extensive investigation including angiographic follow-up by several methods, vascular reactivity, pro-thrombotic mechanisms, genetic and biochemical studies may facilitate the understanding of so-called micro- and macrovascular disease of DM.

Abstract
UNLABELLED An abnormal ratio of triglycerides to HDL-cholesterol (TG/HDL-c) indicates an atherogenic lipid profile and a risk for the development of coronary disease. OBJECTIVE To investigate the association between lipid levels, specifically TG/HDL-c, and the extent of coronary disease. METHODS High-risk patients (n=374) submitted for coronary angiography had their lipid variables measured and coronary disease extent scored by the Friesinger index. RESULTS The subjects consisted of 220 males and 154 females, age 57.2+/-11.1 years, with total cholesterol of 210+/-50.3 mg/dL, triglycerides of 173.8+/-169.8 mg/dL, HDL-cholesterol (HDL-c) of 40.1+/-12.8 mg/dL, LDL-cholesterol (LDL-c) of 137.3+/-46.2 mg/dL, TG/HDL-c of 5.1+/-5.3, and a Friesinger index of 6.6+/-4.7. The relationship between the extent of coronary disease (dichotomized by a Friesenger index of 5 and lipid levels (normal vs. abnormal) was statistically significant for the following: triglycerides, odds ratio of 2.02 (1.31-3.1; p=0.0018); HDL-c, odds ratio of 2.21 (1.42-3.43; p=0.0005); and TG/HDL-c, odds ratio of 2.01(1.30-3.09; p=0.0018). However, the relationship was not significant between extent of coronary disease and total cholesterol [1.25 (0.82-1.91; p=0.33)] or LDL-c [1.47 (0.96-2.25; p=0.0842)]. The chi-square for linear trends for Friesinger >4 and lipid quartiles was statistically significant for triglycerides (p=0.0017), HDL-c (p=0.0001), and TG/HDL-c (p=0.0018), but not for total cholesterol (p=0.393) or LDL-c (p=0.0568). The multivariate analysis by logistic regression OR gave 1.3+/-0.79 (p= .0001) for TG/HDL-c, 0.779+/-0.074 (p= .0001) for HDL-c, and 1.234+/-0.097 (p=0.03) for LDL. Analysis of receiver operating characteristic curves showed that only TG/HDL-c and HDL-c were useful for detecting extensive coronary disease, with the former more strongly associated with disease. CONCLUSIONS Although some lipid variables were associated with the extent of coronary disease, the ratio of triglycerides to HDL-cholesterol showed the strongest association with extent.

Abstract
BACKGROUND SIMPLE II was a multi-centre, prospective registry study aimed at investigating the safety and efficacy of the Infinnium (Sahajanand Medical Technologies Pvt. Ltd, India) paclitaxel-eluting stent for the treatment of single de novo lesions in the native coronary arteries. METHODS One hundred and three patients with symptomatic coronary artery disease were treated for single de novo native coronary artery lesions using the Infinnium stent (paclitaxel concentration 1.4 mcg/mm2 released over 48 days) in a multi-centre, prospective study performed on 3 continents (Asia, Europe and South America). The primary safety endpoint was major adverse cardiac events at 30 days (MACE 30d) and efficacy was assessed by in-stent binary restenosis as measured by quantitative coronary angiography (QCA) at six-month follow-up. A clinical follow-up was scheduled at nine months. RESULTS The mean patient age was 58.5 years; 70.9% were males; 43.7% had unstable angina and 38.8% previous myocardial infarction. Risk factors included hypertension in 62.1%, hypercholesterolemia in 52.4%, current smoking in 32.0% and diabetes in 28.2%. Stent implantation was successful in all patients, with more than one stent being implanted in 9 patients (8.7%). Hierarchical MACE 30d was 2.9%. At nine months, 101 patients had clinical follow-up (1 patient had died and 1 refused). There was one death (1.0%), one Q-wave myocardial infarction (Q MI) (1.0%), three non-Q MIs (2.9%), one clinically-driven target lesion Coronary Artery Bypass Grafting (CABG) (1.0%), and one clinically-driven target lesion repeat percutaneous coronary intervention (re-PCI) (1.0%). The overall event-free rate at nine months was 93.2%. QCA revealed in-stent and in-segment late loss of 0.38+/-0.49 mm and 0.18+/-0.46 mm, resulting in binary restenosis rates of 7.3% and 8.3%, respectively. There was one case of late stent thrombosis in the patient experiencing the Q MI and subsequent re-PCI. CONCLUSIONS The Infinnium paclitaxel-eluting stent appears to be safe and efficacious for the treatment of single de novo lesions in coronary arteries in a patient population with symptomatic coronary artery disease (CAD).

Abstract
Isolated noncompaction of the myocardium (INCM) is a rare, congenital, unclassified cardiomyopathy. It is caused by a disorder in endomyocardial morphogenesis in the absence of other structural disease. INCM is characterized by numerous prominent trabeculations and deep intertrabecular recesses in the myocardium. Frequently, INCM is associated with an increased incidence of heart failure, arrhythmias, and cardioembolic events with high morbidity and mortality. We describe a 28-year-old woman experiencing symptoms of heart failure since she was 4 years old. She had been intensively investigated and misdiagnosed as having dilated, restrictive, and apical hypertrophic cardiomyopathies. Cardiac magnetic resonance and echocardiography recently revealed the actual diagnosis of INCM. The patient is alive and well, taking vasodilators and warfarin. Herein, we describe the long-term follow-up of this patient and demonstrate that some patients have a favorable prognosis. In addition, the improvement in noninvasive cardiac imaging has revealed a higher prevalence of INCM, previously undetected.

Abstract
OBJECTIVES To determine the long term outcome after intracoronary beta radiation therapy (IRT). SETTING Tertiary referral centre. METHODS The rate of major adverse cardiac events (MACE) was retrospectively determined in 301 consecutive patients who were treated with IRT. MACE was defined as death, myocardial infarction, or any reintervention. Long term clinical outcome was obtained from an electronic database of hospital records and from questionnaires to the patients and referring physicians. Long term survival status was assessed by written inquiries to the municipal civil registries. RESULTS The mean (SD) follow up was 3.6 (1.2) years. The cumulative incidence of MACE at six months was 19.1%, at one year 36.4%, and at four years 58.3%. The target lesion revascularisation (TLR) rate at six months was 12.9%, at one year 28.3%, and at four years 50.4%. From multivariate analysis, dose < 18 Gy was the most significant predictor of TLR. At four years the cumulative incidence of death was 3.8%, of myocardial infarction 13.4%, and of coronary artery bypass surgery 11.3%. Total vessel occlusion was documented in 12.3% of the patients. CONCLUSIONS In the long term follow up of patients after IRT, there are increased adverse cardiac events beyond the first six months.

Abstract
From April 16, 2002 to October 16, 2002, 10 consecutive patients with coronary disease on chronic dialysis were treated with sirolimus-eluting stents. Diabetes was present in 30% and half of the patients had multivessel coronary disease. On average, patients had been on dialysis for 5 years prior to the procedure (range: 2-15 years). Five patients were on hemodialysis and 5 patients were on peritoneal dialysis. Overall, 18 lesions were treated with 1.9 +/- 1.1 sirolimus-eluting stents per patient. At a mean follow-up of 403 days, there were no cases of death, myocardial infarction, or target lesion revascularization.

Abstract
This study evaluates the response of the coronary vessel wall to implantation of the sirolimus-eluting stent (SES), Bx-VELOCITY, by using serial intravascular ultrasound. SESs have a major impact on the inhibition of in-stent neointimal hyperplasia. However, changes in the vessel wall and behind stent struts in animal models and humans have not been evaluated after SES implantation. Thirty-four patients who received a SES (n = 24) or a Bx-VELOCITY bare stent (BS) (n = 10) for single de novo coronary lesions and had serial motorized pullback 3-dimensional intravascular ultrasound were included. Stent, lumen, and vessel volumes were similar in the 2 groups at baseline. At follow-up, significantly larger lumen and lower neointimal hyperplasia volumes (0.7 vs 33 mm(3), p = 0.001) were seen in the SES group compared with the BS group. There was no significant difference between SES and BS in either the vessel volume (+2.4% vs +0.7%, p = NS) or the plaque behind stent volume change (+3.4% vs +2.5%, p = NS) from after the procedure to late follow-up. The stent edges also showed no significant difference between postprocedural and follow-up measurements, either in patients receiving SESs or BSs. No stented or edge segment required redilatation in the SES group, whereas 2 patients underwent repeat percutaneous coronary angioplasty in the BS group. In the SES group, 1 patient (4%) showed late acquired incomplete stent apposition. Thus, the SES is effective in inhibiting neointimal hyperplasia without affecting vessel volume and plaque behind the stent.

Abstract
A case of a 43-year-old woman with severe sustained hypertension resistant to many antihypertensive drugs, frequent hypertensive crisis and symptoms suggestive of pheochromocytoma (symptomatic triad) is presented. Three of the four determinations of the urinary catecholamines metabolites have been normal as it was the only determination of plasmatic catecholamines. Abdominal sonography and CT scan detected a left adrenal mass, that have been histologically confirmed, after surgery, to be a pheochromocytoma. After adrenalectomy, the patient symptoms disappeared but she maintained mild hypertension easily controlled with drugs. The finding of normal plasmatic and urinary catecholamines values in a patient with sustained hypertension may suggest that we are handling with a case of essential hypertension and a superimposed pheochromocytoma with paroxysmal secretion. Some considerations are made essentially about specificity and sensitivity of diagnostic tests.
