Mortality is high in patients with post-infarction cardiogenic shock. Reversal of tissue hypoperfusion is essential for organ preservation during the myocardial functional recovery period. The authors report the case of a female patient who, after consecutive episodes of cardiorespiratory arrest, developed cardiogenic shock secondary to spontaneous dissection of the left main coronary artery. After restoration of coronary flow through primary percutaneous intervention with stent implantation, the Impella™ 2.5 circulatory assist device was implanted, which allowed the patient's hemodynamic improvement, contributing to a favorable outcome.

Em pacientes com choque cardiogênico pós-infarto a mortalidade é alta. A reversão da hipoperfusão tecidual é essencial para a preservação orgânica durante o período de recuperação funcional do miocárdio. Relatamos o caso de uma paciente que, após seguidos episódios de parada cardiorrespiratória, evoluiu com choque cardiogênico secundário à dissecção espontânea do tronco de coronária esquerda. Após a restauração do fluxo coronariano, por meio da intervenção percutânea primária com uso de stent, optou-se pelo implante do dispositivo de assistência circulatória Impella® 2.5, que permitiu melhorar as condições hemodinâmicas da paciente, contribuindo para um desfecho favorável.

Background

Although predilation during primary percutaneous coronary intervention offers greater predictability for stent implantation, it is associated with complications that may negatively influence immediate and late outcomes. The objective of this study was to characterize procedures requiring predilation, comparing them to those performed by direct stent implantation.

Methods

Primary percutaneous coronary interventions registered at the Central Nacional de Intervenções Cardiovasculares (CENIC) from 2006 to 2016 were analyzed. The clinical and angiographic profiles of the procedures performed with or without predilation, hospital outcome measures, and predictors of mortality were characterized.

Results

The sample consisted of 17,515 patients. Those who underwent predilation differed from the direct stent implantation group regarding clinical characteristics, with a higher prevalence of elderly, women, and associated comorbidities. In the first group, the rates of calcified lesions, bifurcations, occlusions, and multivessel coronary disease were higher. Intervention failure rates were also higher in patients undergoing predilation, as well as the rates of major adverse cardiac events. In the multiple logistic regression model, the need for predilation was correlated with the occurrence of hospital death.

Conclusions

Primary percutaneous coronary intervention requiring predilation was characterized by a higher prevalence of clinical comorbidities and by angiographic and technical complexity of the procedures. Predilation is an independent predictor of hospital mortality in this clinical setting.

Introdução

Embora a pré-dilatação durante a intervenção coronária percutânea primária confira maior previsibilidade ao implante do stent, ela associa-se a complicações que podem influenciar negativamente em seus resultados imediatos e tardios. O objetivo deste estudo foi caracterizar os procedimentos com necessidade de pré-dilatação, comparando-os àqueles realizados pelo implante direto de stent.

Métodos

Foram analisadas as intervenções coronárias percutâneas primárias cadastradas na Central Nacional de Intervenções Cardiovasculares (CENIC) durante o período de 2006 a 2016, tendo sido caracterizados os perfis clínico e angiográfico dos procedimentos efetivados com ou sem pré-dilatação, aferição de desfechos hospitalares e preditores de mortalidade.

Resultados

A amostra foi composta por 17.515 pacientes. Aqueles submetidos à pré-dilatação diferiram do grupo stent direto, quanto às características clínicas, com maior prevalência de idosos, mulheres e comorbidades associadas. No primeiro, as taxas de lesões calcificadas, bifurcações, oclusões e coronariopatia multiarterial foram maiores. Também foram maiores as taxas de insucesso da intervenção entre pacientes submetidos à pré-dilata

Background

Despite the close association between smoking and atherosclerotic disease development, little is known about the clinical characteristics and outcomes related to percutaneous coronary intervention (PCI) in smokers with acute coronary syndrome in Brazil. This study aimed to analyze the clinical, angiographic, and procedural profile, in addition to in-hospital outcomes, in smokers and non-smokers with acute myocardial infarction with ST-segment elevation (STEMI) submitted to primary or rescue PCI.

Methods

Cross-sectional study of the Central Nacional de Intervenções Cardiovasculares (CENIC) registry between 2006 and 2016. The study population included patients aged ≥ 18 years who presented with STEMI and were submitted to primary or rescue PCI.

Results

A total of 20,319 patients were included, of whom 6,880 (34.4%) were smokers. The group of smokers was significantly younger, male, and with a lower prevalence of comorbidities. At angiography, smokers showed greater complexity, with a higher prevalence of thrombi, long lesions or TIMI flow 0/1. During the procedure, smokers received a lower proportion of drug-eluting stents and thrombus aspiration was more frequent, as well as procedural success (94.2% vs. 92.1%; p < 0.0001). In the univariate analysis, smokers showed lower mortality (2.9% vs. 4.5%; p < 0.0001) and fewer major adverse cardiac events (3.3% vs. 4.8%; p < 0.0001). However, after multivariate analysis, smoking was not associated with a lower risk of mortality.

Conclusions

Although the clinical outcomes associated with the PCI were favorable to smokers, the multivariate analysis did not show a protective effect of smoking. Such results are due to differences in clinical and angiographic characteristics between smokers and non-smokers.

Background

The MGuardTM stent, which has a microscopic polymer mesh coating, is intended to reduce the distal embolization of fragments during percutaneous coronary intervention (PCI) in saphenous vein grafts (SVG). This study evaluated the early and late clinical outcomes of patients undergoing PCI in SVG with MGuardTM stents vs. drug-eluting stents (DES).

Methods

Observational, retrospective study conducted at two tertiary centers, involving a cohort of patients with SVG lesions submitted to elective or emergency treatment with MGuardTM stents or DES.

Results

A total of 271 patients were included, of whom 220 were treated with DES. The MGuardTM group had a higher proportion of women (25.5% vs. 10.5%; p = 0.01), with a mean age of 65.0 ± 13.9 years vs. 69.0 ± 9.6 years (p = 0.06). The DES group more frequently used distal protection filter (5.8% vs. 10.0%; p = 0.001). Angiographic success was attained in most cases (96.2% vs. 98.0%; p = 0.22). The MGuardTM group had lower rates of early major adverse cardiovascular events (MACE) than the DES group (1.9% vs. 13.6%; p = 0.01), due solely to the lower incidence of periprocedural infarction. However, the MACE rate at 1 year was higher in the MGuardTM group (14.3% vs. 4.4%; p = 0.01) at the expense of a higher rate of target lesion revascularization (7.1% vs. 1.3%; p = 0.048).

Conclusions

The use of the MGuardTM stent resulted in a reduction of events during hospitalization; however, in the long term the DES were superior in reducing major outcomes, mainly the need for target lesion revascularization.

Introdução

O stent MGuardTM, revestido por malha polimérica microscópica, tem a finalidade de reduzir a embolização distal de fragmentos durante a intervenção coronária percutânea (ICP) em enxertos de veia safena (EVS). Avaliamos os desfechos clínicos precoces e tardios de pacientes submetidos à ICP de EVS com stents MGuard™ vs. stents farmacológicos (SF).

Métodos

Estudo observacional, retrospectivo, realizado em dois centros terciários, envolvendo uma coorte de pacientes com lesões em EVS, tratados de forma eletiva ou de emergência com stents MGuard™ ou SF.

Resultados

Foram incluídos 271 pacientes, sendo 220 tratados com SF. O Grupo MGuard™ apresentou maior proporção de mulheres (25,5% vs. 10,5%; p=0,01), com média de idades de 65,0 ± 13,9 anos vs. 69,0 ± 9,6 anos (p = 0,06).

Background

Recently, the MOZART study demonstrated that using intravascular ultrasound (IVUS) for guiding percutaneous coronary intervention (PCI) reduces the volume of contrast used in the procedure. The authors assessed the incidence of late adverse cardiovascular events in these patients.

Methods

Patients at risk for contrast-induced nephropathy (CIN) or volume overload were randomized to angiography-guided versus IVUS-guided PCI, and followed-up for a 1-year period.

Results

Eighty-three patients were included in the angiography-guided (n = 42) or IVUS-guided (n = 41) groups, of whom 77.1% were diabetics and 44.6% had creatinine clearance < 60 mL/min/1.73m2. Clinical and angiographic characteristics did not differ between the groups. Most had type B2/C lesions (89.8%) and a median of two stents were used (interquartile range: 1.0-2.0 stents). The duration of IVUS-guided PCI was 14 minutes longer than the angiography-guided PCI group (p = 0.006). However, the groups did not differ regarding fluoroscopy time or mean image acquisitions per procedure. CIN occurred in 19.0% vs. 7.3% (p = 0.26). During the 1-year follow-up, 12% of patients had a major cardiovascular event, with two deaths (one in each group), and no differences were found between groups.

Conclusions

The contrast reduction strategy with IVUS-guided PCI in patients at risk for CIN or volume overload was shown to be safe in the short and long term.

Introdução

Recentemente, o estudo MOZART demonstrou que a utilização do ultrassom intracoronário (USIC) para guiar a intervenção coronariana percutânea (ICP) diminui o volume de contraste utilizado no procedimento. Avaliamos a incidência de eventos adversos cardiovasculares tardios desses pacientes.

Métodos

Pacientes com risco para nefropatia induzida por contraste (NIC) ou para sobrecarga de volume, e com indicação de ICP, foram randomizados para procedimento guiado pela angiografia ou USIC, e acompanhados por um período de 1 ano.

Resultados

Incluídos 83 pacientes nos grupos ICP guiado por angiografia (n = 42) ou USIC (n = 41), sendo que 77,1% eram diabéticos e 44,6% tinham clearance de creatinina < 60 mL/min/1,73m2. As características clínicas e angiográficas não mostraram diferenças entre os grupos. A maioria tinha lesões tipo B2/C (89,8%) e uma mediana de dois stents foram usados (intervalo interquartil: 1,0-2,0 stents). O tempo de procedimento da ICP guiada por USIC foi 14 minutos maior do que no grupo guiado por angiografia (p = 0,006). No entanto, os grupos não diferiram em relação ao tempo de fluoroscopia ou à média de aquisições de imagem por procedimento. A NIC ocorreu em 19,0% vs. 7,3% (p = 0,26). No período de seguimento de 1 ano, 12% dos pacientes apresentaram algu

Background

Severe stenosis of the proximal left anterior descending artery (LAD) is classified as a high-risk lesion, as it may affect a large part of the left ventricular myocardium. Second-generation drug-eluting stents (DES) have been shown to be more effective and safer when compared to bare-metal or first-generation ones. There are few reports in the literature on the use of these devices for the treatment of isolated lesions in the proximal LAD.

Methods

Observational and prospective study, which included single-vessel patients with de novo lesions in the proximal LAD, electively treated with second-generation DES. In-hospital and late clinical outcomes were evaluated.

Results

Seventy patients were included, most of them males (70%), with a mean age of 65.4 ± 11.2 years and a high prevalence of diabetes (37%). The most common clinical presentation was stable angina (57.1%) and half of the lesions were type B2 or C. A total of 70 lesions were treated with 71 stents, with 100% angiographic success. The primary endpoint, consisting of cardiac death, nonfatal infarction, or target-vessel revascularization during the 2.5-year clinical follow-up, occurred in 3% of the patients. Cardiac death was 1.5%, and target-lesion revascularization was required in only 1.5% of the patients.

Conclusions

Elective treatment with second-generation DES seems to be a safe option in single-vessel patients with de novo lesions in the proximal LAD, with low rates of adverse cardiac events or need for additional revascularization procedure.

Introdução

A estenose grave do terço proximal da artéria descendente anterior (ADA) é classificada como lesão de alto risco, visto que pode comprometer grande parte do miocárdio ventricular esquerdo. Os stents farmacológicos (SF) de segunda geração têm demonstrado maior eficácia e segurança quando comparados aos não farmacológicos ou aos de primeira geração. São escassos os relatos na literatura do emprego desses dispositivos para o tratamento de lesões isoladas do terço proximal da ADA.

Métodos

背景:严重的左前降支近端狭窄(LAD)被列为高危病变,因为它可能影响大部分左心室心肌。第二代药物洗脱支架(DES)已被证明比裸金属支架或第一代药物洗脱支架更有效和更安全。文献中很少有关于使用这些装置治疗LAD近端孤立病变的报道。方法观察性前瞻性研究,纳入单血管LAD近端新发病变患者,选择性使用第二代DES治疗,评估住院和晚期临床结果。结果入选患者70例,男性居多(70%),平均年龄65.4±11.2岁,糖尿病患病率较高(37%)。最常见的临床表现为稳定型心绞痛(57.1%),半数病变为B2型或c型。共使用71支支架治疗70个病变,血管造影成功率100%。在2.5年的临床随访中,主要终点包括心源性死亡、非致死性梗死或靶血管重建术,发生在3%的患者中。心源性死亡占1.5%,仅1.5%的患者需要靶区血管重建术。结论:对于LAD近端新生病变的单血管患者,选择性治疗第二代DES似乎是一种安全的选择,心脏不良事件发生率低,无需额外的血运重建术。导论: 近端颈动脉近端颈动脉前部降速(ADA) 分类性颈动脉前部病变(classficada como les.com),与miocárdio脑室前部病变(visto que pode comprometer grande partte do ventricular esquerdo)。Os stents farmacológicos (SF) de segunda gera o têm demonstrado major eficácia e segurana quando comparados aos n o farmacológicos ou aos de primeira gera o。本文对近端ADA中lesões孤立性ADA的治疗方法进行了分析,并对相关文献进行了探讨。该研究的观察性和前瞻性研究,包括单一动脉病变的观察性研究、近端动脉病变的观察性研究、近端动脉病变的观察性研究和近端动脉病变的观察性研究。Avaliamos os desfechos clínicos hospitalares e tardios。结果有孔虫病incluídos 70例,男性性多发症(70%),有孔虫病(66.5±11.2)例,有孔虫病prevalência(37%)例。O quadro clínico最常用于心绞痛estável (57.1%); e metade das lesões (57.1%); C.

Transcatheter aortic valve implantation is a well-established therapy in patients with severe aortic stenosis. There has been a progressive improvement in device technology associated with increased experience of the interventionists, resulting in safer procedures with better outcomes. The first second-generation device approved in Brazil, Lotus™ Valve System (Boston Scientific Corporation, Natick, USA), incorporates several of these new characteristics. This report describes the first two cases, both successfully performed in the country, carried out under local anesthesia and conscious sedation.

O implante percutâneo de bioprótese aórtica é a terapia estabelecida em pacientes com estenose aórtica grave. Houve um progressivo aperfeiçoamento na tecnologia dos dispositivos que, associada a maior experiência dos operadores, resultou em procedimentos mais seguros e com melhores resultados. O primeiro dispositivo de segunda geração aprovado no Brasil, o sistema de válvula Lotus™ (Boston Scientific Corporation, Natick, EUA), incorpora várias dessas novas características. Descrevemos aqui os dois primeiros casos realizados no país, conduzidos sob anestesia local e sedação consciente, ambos com sucesso.
