Background

Patients undergoing transradial procedures may experience pain associated with radial artery spasm. The pain can be assessed using the Visual Analogue Scale (VAS), an easy-to-apply, one-dimensional method. This study analyzed the perception of pain using the VAS and correlated it with the perception of spasm by the interventionist.

Methods

This was an observational, prospective, single-center registry, which included patients undergoing diagnostic or therapeutic transradial procedures. The VAS consists of a 100-mm horizontal line, which has at its extremes the words “no pain” and “unbearable pain”. The patient was instructed to identify the point that represented the perceived pain during the procedure. The interventionist quantified the spasm as zero for no pain, 1 for pain with no resistance to catheter movement, 2 for mild resistance, 3 for moderate resistance, and 4 for intense resistance.

Results

Pain assessment by patients using the VAS was possible in all patients, and had a mean of 25.5 ± 25.7 mm. For the interventionist, spasm was classified as grade zero in 53 cases (35.8%); grade 1 in 67 (45.3%); grade 2 in 24 (16.2%); grade 3 in 3 (2.0%); and grade 4 in 1 patient (0.7%). Kendall's tau-b and Spearman's (rho) rank correlation coefficients were, respectively, 0.527 and 0.647, showing a moderate positive correlation between the perception of pain by the patient and the perception of spasm by the operator.

Conclusions

VAS can be used to assess spasm during procedures that use the transradial access, showing a positive correlation with spasm assessment by the interventionist.

Introdução

Pacientes submetidos a procedimentos por via transradial podem apresentar dor associada ao espasmo da artéria radial. A dor pode ser avaliada utilizando-se a Escala Visual Analógica (EVA), um método unidimensional de fácil aplicação. Analisamos a percepção de dor utilizando a EVA e a correlacionamos com a percepção de espasmo pelo operador.

Métodos

Registro observacional, prospectivo, unicêntrico, que incluiu pacientes submetidos a procedimentos diagnósticos ou terapêuticos por acesso transradial. A EVA é constituída por uma linha horizontal de 100 mm, que traz nos extremos as inscrições “ausência de dor” e “dor insuportável”. O paciente foi instruído a marcar o ponto que representava a dor percebida no momento do procedimento. O operador quantificou o espasmo como zero se sem dor, 1 para dor sem resistência à movimentação dos cateteres, 2 para resistência leve, 3 para resistência moderada e 4 para resistência intensa.

Resultados

A avaliação de dor pelo paciente por meio da EVA foi possível em todos os pacientes, e teve média de 25,5 ± 25,7 mm. Pelo operador, o espasmo foi classificado em grau zero em 53 casos (35,8%); grau 1 em 67 (45,3%); grau 2 em 24 (

Background

Transesophageal echocardiography (TEE) is the most widely used method to guide the percutaneous treatment of atrial septal defect (ASD) and patent foramen ovale (PFO), but the necessity of another professional to perform it and the need for general anesthesia are potential disadvantages. Intracardiac echocardiography (ICE) is seen as an alternative to TEE, as it can be performed by the interventionist and requires only local anesthesia with mild or no sedation. The aim of this study was to report our experience with ASD/PFO occlusion guided by ICE.

Methods

The ICE uses an ultrasound catheter, which is intravenously inserted in the right heart chambers and acquires images for the intervention through variable positioning of the transducer. Success and complication rates of the procedure were evaluated.

Results

From 2011 to 2015, 201 procedures guided by ICE were performed, comprising 139 in patients with ASD and 62 in those with PFO. Most patients were female (64.2%), ages ranged from 7 to 78 years (36.6 ± 19.3 years), and weight ranged from 28 to 92 kg (62.5 ± 13.0 kg). Occlutech Figulla® prostheses were used and all interventions were successful, with fluoroscopy time of 5.7 ± 2.4 minutes and procedure time of 21.5 ± 6.4 minutes. Two patients (2.0%) had transient supraventricular tachycardia and two others had arteriovenous fistula at the access site, with spontaneous resolution in the first month of follow-up.

Conclusions

ICE provided accurate anatomical information to guide the closure of the ASD/PFO and successfully eliminated the main drawbacks of TEE.

Introdução

O ecocardiograma transesofágico (ECO-TE) é o método mais utilizado para guiar o tratamento percutâneo da comunicação interatrial (CIA) e do forame oval (FOP), mas a necessidade de um outro profissional para realizá-lo e de anestesia geral constituem inconvenientes para seu emprego. O ecocardiograma intracardíaco (ECO-IC) apresenta-se como alternativa ao ECO-TE, pois pode ser realizado pelo próprio operador e demanda apenas anestesia local, com leve ou nenhuma sedação. Nosso objetivo foi relatar a experiência do serviço com a oclusão de CIA/FOP guiada por ECO-IC.

Métodos

O ECO-IC utiliza cateter de ultrassom, que é introduzido por via venosa em câmaras cardíacas direitas e, por meio de posicionamento variável do transdutor, obtém as imagens adequadas para a intervenção. Foram avaliadas as taxas de sucesso do procedimento e as complicações.

Background

Percutaneous mitral valvuloplasty is the treatment of choice for rheumatic mitral stenosis with favorable anatomy, for its ability to prevent complications inherent to a surgical procedure, while maintaining effectiveness. It is necessary to promote comparisons between the results obtained by the procedure performed at referral centers with high patient inflow and at institutions with lower volume and fewer patients, which represents the main objective of this study.

Methods

Thirty-one consecutive patients undergoing percutaneous mitral valvuloplasty were analyzed from September 2006 to January 2015. Immediate procedural success and late event-free survival rates were evaluated, defined as cardiovascular death or need for a new mitral valve intervention.

Results

The mean age was 40.9 ± 14.2 years, with a predominance of females (96.8%). The mean Wilkins and Block score was 8.1 ± 1.2. All procedures were performed using the Inoue technique, with an immediate success rate of 90.3%. At mean follow-up of 6.8 ± 2.5 years, seven events (22.6%) were observed: two cardiovascular deaths, four surgeries for mitral valve replacement, and one mitral commissurotomy.

Conclusions

In a hospital with intermediate procedure volume, the results of percutaneous mitral valvuloplasty in the treatment of rheumatic mitral stenosis with favorable anatomy were comparable to those achieved by high-volume centers.

Background

Initial studies have shown that old occlusions or those with indeterminate occlusion duration have been associated with percutaneous coronary intervention (PCI) failure and a worse prognosis. This study aimed to determine the impact of occlusion duration on the success and outcomes of contemporary PCI on chronic total occlusion (CTO).

Methods

The authors analyzed a retrospective cohort of consecutive patients submitted to PCI in CTO, who were compared according to the confirmed occlusion duration (COD) < 12 months, ≥ 12 months, or indeterminate occlusion duration (IOD).

Results

A total of 168 patients were treated, 122 (72.6%) with COD (80 < 12 months, 42 ≥ 12 months) and 46 (24.7%) with an IOD. Lesion extension was 17.0 ± 13.6 mm, in 2.90 ± 0.58 mm vessels, and the anterograde approach was used in 98.8% of cases. Angiographic success was attained in 79.2% of patients (80.0% vs. 73.8% vs. 82.6%; p = 0.73). The main cause of failure was the inability to cross the lesion with the guidewire (68.6%). Occlusion duration had no impact on in-hospital events (4.8% vs. 7.1% vs. 6.0%; p = 0.73), which were almost entirely explained by periprocedural myocardial infarction, or on late outcomes (18.8% vs. 7.1% vs. 15.3%; p = 0.23). At the multivariate analysis, lesion length ≥ 20 mm (odds ratio - OR = 7.27; 95% confidence interval - 95% IC 1.94-29.1; p = 0.003), calcification (OR = 4.72; 95% CI 1.19-19.1; p = 0.02), and tortuosity of the occluded segment (OR = 15.98; 95% CI 2.18-144.7; p = 0.007) were predictors of failure.

Conclusions

Occlusion duration was not associated with increased failure rate of the procedure or worse PCI outcomes in CTO.

Introdução

Estudos iniciais mostram que oclusões antigas ou com tempo indeterminado têm sido associadas a insucesso da intervenção coronária percutânea (ICP) e a pior prognóstico. Nosso objetivo foi determinar o impacto do tempo de oclusão no sucesso e nos resultados da ICP contemporânea na obstrução total crônica (OTC).

Métodos

Analisamos uma coorte retrospectiva de pacientes consecutivos que realizaram ICP em OTC, e que foram comparados de acordo com o tempo de oclusão confirmado (TOC) < 12 meses, ≥ 12 meses, ou indeterminado (TOI).

Resultados

Foram tratados 168 pacientes, 122 (72,6%) com TOC (80 < 12 meses, 42 ≥ 12 meses) e 46 (24,7%) com TOI. A extensão da lesão foi de 17,0 ± 13,6 mm, em vasos de 2,90 ± 0,58 mm, e a abordagem anterógrada foi utilizada em 98,8% dos casos. Sucesso angiográfico foi obtido em 79,2% dos pacientes (80,0% vs. 73,8% vs. 82,6%; p = 0,73). A principal causa de insucesso foi a incapacidade de cruzar a lesão com o fio-guia (68,6%). O tempo de oclusão não teve impacto na taxa de eventos cardiovas

Background

Atrial fibrillation (AF) increases the risk of thromboembolic events caused by emboli originating in the left atrial appendage (LAA). Mechanical methods for LAA occlusion have been developed as an alternative to oral anticoagulation. The aim of this study was to present an initial experience with the AMPLATZER® Cardiac Plug.

Methods

Patients with permanent or paroxysmal AF and with contraindications or complications of oral anticoagulation were included. Patients with LAA anatomy and measures compatible with the occluder, and without thrombi, were selected through transesophageal echocardiography.

Results

A total of 14 procedures were performed in 13 patients (5 M:8F), with mean age of 66.7 years. Significant bleeding and previous strokes were found in 69.2% and 53.8%, respectively. AF was permanent in 84.6% and paroxysmal in the remainder. The mean diameters of the ostium and the landing zone were 23.9 mm and 20.8 mm, respectively. Bilobulated LAA was observed in 76.9%. Procedures were possible in all cases. Sixteen devices were used in 13 patients, a ratio of 1.2:1, and only one patient required a second device for LAA occlusion. The mean follow-up was 12.2 months. All LAA remain closed, with no residual defect to date. There was only one late death, unrelated to the procedure.

Conclusions

LAA occlusion using the AMPLATZER® Cardiac Plug device was shown to be safe and effective in this small series of patients. The initial results are encouraging and indicate the transcatheter closure of the LAA as an alternative to oral anticoagulation therapy in selected patients.

Background

Complete anatomical myocardial revascularization is associated with better angina control and lower rates of cardiac events. However, in a significant number of patients treated by percutaneous coronary intervention (PCI), complete revascularization is not achieved. Thus, the aim of this study was to evaluate factors associated with incomplete myocardial revascularization (IMR) in multivessel PCI patients.

Methods

This was a cohort study involving 1,049 prospectively and consecutively revascularized patients through PCI with treatment of two or more vessels, between 2012 and 2014, divided into two groups: IMR (n = 324; 30.9%) and complete myocardial revascularization (n = 725; 69.1%).

Results

IMR was significantly associated with older age (66.5 years vs. 64.1 years; p = 0.003), arterial hypertension (92.2% vs. 86.0%; p = 0.006), chronic renal failure (36.4% vs. 26.0%; p < 0.001), acute coronary syndrome (26.3% vs. 21.0%; p = 0.05), previous surgical revascularization (16.1% vs. 7.1%; p = 0.001), saphenous venous graft lesions (3.4% vs. 1.0%, p < 0.001), and chronic occlusions (3.3% vs. 1.4%, p = 0.005), as well as lower access to drug-eluting stents (57.8% vs. 64.8%; p = 0.002). In-hospital clinical outcomes did not differ between the groups.

Conclusions

IMR occurred in approximately one-third of treated cases, and a significant association was observed with a higher-risk clinical profile and with target lesion interventions commonly associated with lower procedure success. The degree of revascularization had no impact on in-hospital clinical outcomes.

Introdução
