Avaliação dos efeitos do curativo compressivo após procedimentos intervencionistas por via radial / Evaluation of the effects of compressive dressing after interventional procedures via radial approach

Introdução: Dispositivos externos compressivos após a punção radial para cateterismo cardíaco e intervenção coronária percutânea visam à hemostasia, ao conforto para o paciente e à segurança. O estudo objetivou avaliar pacientes submetidos a procedimentos coronários invasivos por via radial, nos quais se utilizou um curativo compressivo e de baixo custo, desenvolvido no serviço, avaliando a segurança dele e a ocorrência de complicações. Métodos: Indivíduos submetidos à coronariografia e à intervenção coronária percutânea, avaliados no momento de retirada do curativo compressivo e após 7 dias, por meio de questionário abrangendo comorbidades, quadro clínico, tempo do procedimento e de compressão, avaliação física de hematoma e dor, e Doppler vascular sonoro para avaliação de oclusão da artéria radial. Resultados: Foram avaliados 144 pacientes, sendo 138 com seguimento em 7 dias. Os eventos não diferiram entre procedimentos diagnósticos e terapêuticos. Na avaliação imediata à retirada do curativo, revelou-se incidência de 4,2% de oclusão da artéria radial, com dor referida em 23,6% dos pacientes, graduada em 2,9±1,7 pela Escala Visual Analógica (intensidade de zero a dez) e sem sangramentos graves. Hematoma ocorreu em um paciente (0,9%), com classificação III pelo critério EASY. Na avaliação de 7 dias, a incidência de oclusão da artéria radial foi de 2,2%, a dor foi referida em 11,1% da amostra (intensidade 1,8±0,8), e o hematoma foi evidenciado em 3,5%. Conclusão: O curativo compressivo mostrou-se um procedimento seguro, com baixa taxa de complicações e baixa taxa de dor local nos pacientes submetidos a procedimentos coronários invasivos pela via radial.

Background: External compressive devices after radial puncture for cardiac catheterization and percutaneous coronary intervention aim at hemostasis, patient comfort, and safety. The objective of the study was to evaluate patients undergoing invasive coronary procedures by radial approach, in which a low-cost compressive dressing developed at the service was used, assessing its safety and the occurrence of complications. Methods: Patients undergoing coronary angiography and percutaneous coronary intervention, evaluated at the time of removal of compressive dressing and after 7 days, by means of a questionnaire addressing comorbidities, clinical picture, procedure and compression time, physical assessment of hematoma and pain, and a vascular Doppler ultrasound to evaluate radial artery occlusion. Results: A total of 144 patients were evaluated, 138 of whom were followed up within 7 days. Events did not differ among diagnostic and therapeutic procedures. In the immediate evaluation after removal of dressing, an incidence of 4.2% of radial artery occlusion was observed, with pain reported by 23.6% of patients, graded at 2.9±1.7 points in the Visual Analogue Scale (intensity of zero to ten), and no major bleeding. Hematoma occurred in one patient (0.9%), classified as type III according to the EASY criteria. In the 7-day evaluation, the incidence of radial artery occlusion was 2.2%, pain was reported in 11.1% of sample (intensity 1.8±0.8), and hematoma was evident in 3.5%. Conclusion: The compressive dressing proved to be a safe procedure, with a low rate of complications and a low rate of local pain in patients undergoing invasive coronary procedures via radial approach.

Eficácia da Hidratação Oral na Prevenção da Nefropatia Induzida por Contraste em Indivíduos Submetidos a Intervenções Coronárias Eletivas / Effectiveness of Oral Hydration in Preventing Contrast-Induced Nephropathy in Individuals Undergoing Elective Coronary Interventions

Resumo Fundamento A nefropatia induzida por contraste (NIC) é definida como deterioração da função renal, representada por um aumento da creatinina sérica ≥25% ou ≥0,5 mg/dL até 72 horas após a exposição ao meio de contraste iodado (MCI). A medida preventiva mais eficaz até o momento é a hidratação venosa (HV). Pouco se sabe sobre a eficácia da hidratação oral (HO) ambulatorial. Objetivo Investigar se a HO ambulatorial com água é tão eficaz quanto a HV com solução salina a 0,9% na prevenção de NIC em procedimentos coronarianos eletivos. Métodos Neste estudo observacional retrospectivo, foram analisados prontuários médicos e dados laboratoriais para coletar dados de indivíduos submetidos a procedimentos coronarianos percutâneos com MCI. Os dados coletados entre 2012 e 2015 avaliaram indivíduos que foram submetidos à HV e entre 2016 e 2020 (após a implementação de um protocolo de HO), os indivíduos que foram submetidos à HO em casa antes e depois de procedimentos coronarianos, conforme orientação da equipe de enfermagem. A significância estatística adotada foi de α=0,05. Resultados No total, 116 pacientes foram incluídos neste estudo, 58 no grupo HV e 58 no grupo HO. Observou-se incidência de NIC de 15% (9/58) no grupo que recebeu HV e 12% (7/58) no grupo que recebeu HO (p=0,68). Conclusão O protocolo de HO realizado pelo paciente parece ser tão eficaz quanto o protocolo de HV hospitalar na proteção renal de indivíduos suscetíveis a desenvolver NIC em intervenções coronarianas eletivas. Essas descobertas devem ser testadas em ensaios mais abrangentes.

Abstract Background Contrast-induced nephropathy (CIN) is defined as worsening renal function, represented by an increase in serum creatinine of ≥ 25% or ≥ 0.5 mg/dL up to 72 h after exposure to iodinated contrast medium (ICM). The most effective preventive measure to date is intravenous hydration (IVH). Little is known about the effectiveness of outpatient oral hydration (OH). Objetive To investigate whether outpatient OH with water is as effective as IVH with 0.9% saline solution in preventing CIN in elective coronary procedures. Methods In this retrospective observational study, we analyzed the medical records and laboratory data of individuals undergoing percutaneous coronary procedures with ICM. Data collected between 2012 and 2015 refer to individuals who underwent IVH and those collected between 2016 and 2020 (after implementation of an OH protocol) correspond to individuals who underwent OH at home before and after coronary procedures as instructed by the nursing team. Statistical significance was established at α = 0.05. Results In total, 116 patients were included in this study: 58 in the IVH group and 58 in the OH group. An incidence of CIN of 15% (9/58) was observed in the group that received IVH and an incidence of 12% (7/58) was seen in the group that received OH (p = 0.68). Conclusion The OH protocol, performed by the patient, appears to be as effective as the in-hospital IVH protocol for the renal protection of individuals susceptible to CIN in elective coronary interventions. These findings should be put to test in larger trials.

Efeito da nitroglicerina no espasmo e na oclusão da artéria radial em cateterismos transradiais realizados em mulheres / Effect of nitroglycerin on radial artery spasm and occlusion in transradial catheterizations performed in women

Introdução: O benefício do cateterismo transradial já foi confirmado em pacientes do sexo feminino. Mulheres submetidas a exames por cateterismo transradial apresentam desafios únicos. A ocorrência de espasmo e oclusão da artéria radial após o procedimento é maior em mulheres. Objetivamos avaliar o benefício da nitroglicerina na redução de espasmo e oclusão da artéria radial em mulheres submetidas a cateterismo transradial. Métodos: Estudo multicêntrico, prospectivo, randomizado 2x2 fatorial, duplo-cego. Participantes foram randomizados para nitroglicerina 500mcg ou placebo em dois momentos: após colocação do introdutor hemostático e antes da retirada. A avaliação de espasmo da artéria radial foi clínica, por meio de escala dor. A avaliação da oclusão da artéria radial foi realizada com Doppler, nas primeiras 12 horas. Resultados: Foram incluídos 2.040 pacientes, sendo 774 (37,5%) mulheres. A média de idade foi similar entre os sexos (62,2 anos versus 61,5 anos; p=0,27). A incidência de espasmo da artéria radial foi maior nas mulheres (21,2% versus 6,6%; p<0,01), bem como a incidência de oclusão da artéria radial (3,4% versus 1,8%; p=0,03). O uso da nitroglicerina no início do procedimento não reduziu a incidência de espasmo da artéria radial em mulheres quando comparado com o placebo (19,7% versus 22,6%; p=0,34), tampouco as taxas de oclusão da artéria radial (4,3% versus 2,5%; p=0,17). O uso da nitroglicerina ao fim do procedimento não reduziu a incidência de oclusão da artéria em mulheres (2,8% versus 3,9%; p=0,37). Conclusões: O espasmo e a oclusão da artéria radial são mais frequentes em mulheres submetidas a cateterismo transradial quando comparadas aos homens. O uso da nitroglicerina não apresenta efeito benéfico na redução dessas incidências.

Background: The benefit of transradial catheterization is well established in female patients. Women undergoing transradial catheterization exams present with unique challenges. The occurrence of radial artery spasm and occlusion after the procedure is higher in women. The objective of this study was to evaluate the benefit of nitroglycerin in reducing radial artery spasm and occlusion in women undergoing transradial catheterization. Methods: This was a 2x2 factorial randomized, multicenter, prospective, double-blinded study. Participants were randomized to nitroglycerin 500mcg or placebo at two time points: after placement of the hemostatic introducer and before its removal. The evaluation of the radial artery spasm was clinical, using a pain scale The evaluation of the radial artery occlusion was performed with Doppler, in the first 12 hours. Results: A total of 2,040 patients were included, of which 774 (37.5%) were female. Mean age was similar between sexes (62.2 years versus 61.5 years; p=0.27). The incidence of radial artery spasm was higher in women (21.2% versus 6.6%; p<0.01), as well as the incidence of radial artery occlusion (3.4% versus 1.8%; p=0.03). The use of nitroglycerin at the beginning of the procedure did not reduce the incidence of radial artery spasm in women when compared with placebo (19.7% versus 22.6%; p=0.34), nor did the rates of radial artery occlusion (4.3% versus 2.5%; p=0.17). The use of nitroglycerin at the end of the procedure did not reduce the incidence of artery occlusion in women (2.8% versus 3.9%; p=0.37). Conclusions: Radial artery spasm and occlusion are more frequent in women undergoing transradial catheterization when compared to men. The use of nitroglycerin does not have a beneficial effect in reducing these incidences.

The predictive value of CT pulmonary angiography combined with echocardiography for the degree of pulmonary hypertension / 西安交通大学学报(医学版)

【Objective】 To compare the value of CT pulmonary angiography (CTPA) and echocardiography in predicting the degree pulmonary hypertension (PH). 【Methods】 Fifty-four patients in our hospital who underwent right heart catheterization, CTPA and echocardiography for suspected or confirmed PH from November 2013 to April 2021 were retrospectively recruited. Pulmonary artery systolic pressure (PASP) and mean pulmonary artery pressure (PAMP) were measured by right heart catheterization. According to PAMP, the patients were divided into non-PH group and mild, moderate, and severe PH groups. The three-dimensional model of the pulmonary artery was obtained by computer-aided segmentation, and the best fitting circle diameter (Dfit), inscribed circle diameter (Dmin), circumscribed circle diameter (Dmax), hydraulic diameter (Dh), cross-sectional area (Area), circumference (Scf), and the largest area and largest short diameter of the right ventricle were measured. Echocardiography was used to estimate PASP. The differences in the above parameters between different PH groups were compared, the correlations of the above parameters with PASP and PAMP were analyzed, and statistically significant indicators were included to establish three predictive models of PAMP (Model 1: CTPA pulmonary artery; Model 2: CTPA pulmonary artery+CTPA right ventricle; Model 3: CTPA pulmonary artery+CTPA right ventricle+echocardiography), and receiver operating characteristic (ROC) curves were used to compare the diagnostic performance of the three models. 【Results】 Some parameters of main pulmonary artery (Dfit, Dmin, Dmax, Dh, Area, Scf), right pulmonary artery (Dmax, Dh, Area, Scf), left pulmonary artery (Dfit), and right ventricular short diameter increased with the increase of PAMP (P<0.05). Dfit, Dmin, Dh, and area of main pulmonary artery, right pulmonary artery and left pulmonary artery were positively correlated with PASP and PAMP (P<0.05). Right ventricular short diameter and right ventricular maximum area were positively correlated with PASP (P<0.05), and right ventricular short diameter was positively correlated with PAMP (P<0.05). The estimated value of pulmonary artery systolic blood pressure in echocardiography was positively correlated with PASP and PAMP (P<0.05). Model 1, Model 2 and Model 3 could all be used to identify mild PH and moderate PH, among which Model 3 had the best performance in identifying non-PH and mild PH, moderate PH and severe PH. 【Conclusion】 CTPA and echocardiography are helpful in assessing the degree of PH, and the combination of the two has better accuracy in distinguishing non-PH from mild PH, moderate and severe PH.

Perfil clínico e hemodinâmico de pacientes consecutivos com estenose aórtica valvar estudados na era pré-implante transcateter valvar aórtico em instituição acadêmica. Análise comparativa da avaliação invasiva com a ecocardiográfica / Clinical and hemodynamic profile of consecutive patients with aortic valve stenosis studied in the pre-transcatheter aortic valve implantation era at an academic institution. Comparative analysis of invasive evaluation with echocardiography

Introdução: Face à melhor compreensão da fisiopatologia da estenose valvar aórtica, cresceu paralelamente a complexidade da avaliação de sua gravidade, persistindo relevante incerteza quanto à aplicabilidade dos métodos invasivos pelo cateterismo cardíaco e os não invasivos, com base em ecocardiografia. O objetivo deste estudo foi analisar os padrões hemodinâmicos da avaliação com ecocardiografia comparativamente à estimativa da gravidade da estenose aórtica com o cateterismo em pacientes consecutivos referidos para avaliação diagnóstica por laboratório de hospital acadêmico terciário no triênio 2016-2018. Métodos: Estudo observacional, descritivo e retrospectivo das características clínicas e dos resultados das avaliações da gravidade da estenose valvar aórtica obtidas em 96 pacientes consecutivos, por meio de cateterismo e ecocardiografia. Resultados: Amostra populacional de 49 homens e 47 mulheres, com mediana de idade de 66,5 (56,5 a 72,8) anos, estenose valvar aórtica degenerativa em 49% e reumática em 40%, além de diversas comorbidades, inclusive doença coronária (37%). Pelo cateterismo, com base no gradiente pico de 48 (20 a 68), a estenose valvar aórtica foi avaliada como grave em 56%, sendo a pressão telediastólica ventricular de 20mmHg (16 a 30mmHg). Pela ecocardiografia, a área valvar foi 0,9cm2 (0,7 a 1,2cm2), sendo indexado 0,5cm2/m2 (0,43 a 0,5cm2/m2), com gradiente pico de 62±26 mmHg. A estenose valvar aórtica foi considerada severa em 69,2%. Houve discordância entre os métodos sobre a severidade da estenose valvar aórtica em 30% dos exames, com coeficiente de Spearman entre área valvar pelo ecocardiograma e gradiente pico pelo cateterismo de -0,7 (p<0,001). Conclusão: Em amostra representativa dos vários padrões hemodinâmicos, a avaliação da gravidade da estenose valvar aórtica, como praticada rotineiramente em laboratório acadêmico, limitou-se à medida de pico de gradiente transvalvar. A estimativa da área valvar pelo método ecocardiográfico, sendo indireta e também passível de crítica, contribui para as discrepâncias encontradas, tornando-se justificável buscar o aperfeiçoamento de ambos os métodos, em vista da complexidade clínica e hemodinâmica detectada.

Background: In view of the better understanding of the pathophysiology of aortic valve stenosis, the complexity of assessing its severity has simultaneously grown, with relevant uncertainty persisting as to the applicability of invasive methods by cardiac catheterization and non-invasive methods based on echocardiography. The objective of this study was to analyze the hemodynamic patterns of evaluation with echocardiography compared to the estimation of severity of aortic stenosis with catheterization in consecutive patients referred for diagnostic evaluation by the laboratory of a tertiary academic hospital in the 2016 to 2018 triennium. Methods: An observational, descriptive and retrospective study of clinical characteristics and results of assessments of severity of aortic valve stenosis obtained in 96 consecutive patients, through catheterization and echocardiography. Results: A population sample of 49 men and 47 women, with a median age of 66.5 (56.5 to 72.8) years, degenerative aortic valve stenosis in 49%, and rheumatic aortic stenosis in 40%, in addition to several comorbidities, including coronary disease (37%). Using catheterization, based on the peak gradient of 48 (20 to 68), aortic valve stenosis was assessed as severe in 56%, with ventricular end-diastolic pressure of 20mmHg (16 to 30mmHg). Using echocardiography, the valve area was 0.9cm2 (0.7 to 1.2cm2), indexed valve area was 0.5cm2/m2 (0.43 to 0.5cm2/m2), with peak gradient of 62±26mmHg. Aortic valve stenosis was considered severe in 69.2%. There was disagreement between the methods regarding severity of aortic valve stenosis in 30% of exams, with a Spearman coefficient between the valve area on the echocardiogram and the peak gradient on catheterization of -0.7 (p<0.001). Conclusion: In a representative sample of various hemodynamic patterns, the assessment of severity of aortic valve stenosis, as routinely practiced in an academic laboratory, was limited to measuring the peak transvalvular gradient. The estimation of the valve area using the echocardiographic method was indirect and also subject to criticism, and contributed to the discrepancies found, rendering it justifiable to seek the improvement of both methods, in view of the clinical and hemodynamic complexity detected.

Conclusion Participants' experience with EMIRA was positive, suggesting good acceptability of CI by people awaiting unscheduled catheterization in the emergency unit.

Tratamiento intervencionista de las cardiopatías congénitas con hiperflujo pulmonar / Interventional treatment of congenital heart defects with pulmonary hyperflow

Resumen Introducción: En los últimos años se han desarrollado diversos dispositivos oclusores que permiten evitar la cirugía cardíaca en los pacientes con cardiopatías congénitas con hiperflujo pulmonar. Objetivo: Describir la experiencia en el cierre percutáneo de las cardiopatías con hiperflujo. Método: Mediante un estudio descriptivo y retrospectivo se revisaron las historias clínicas de los pacientes sometidos a intervencionismo cardíaco de 2016 a 2020. Resultados: De 706 procedimientos realizados en el periodo, el 35% fueron terapéuticos. De ellos, 189 correspondieron a nuestra serie de pacientes intervenidos con diagnósticos de persistencia del conducto arterioso (PCA) (n = 164), comunicación interauricular (CIA) (n = 21) y comunicación interventricular (CIV) (n = 4). Los datos clínicos y demográficos fueron en PCA 3.4 años (0.7-15) y 10.2 kg (6.1-46), en CIA 7.2 años (6-15) y 17.5 kg (15-38), y en CIV 7.25 años (6-9) y 20.75 kg (16-27). Referente al tamaño de los defectos cardíacos, el promedio fue para PCA 4.3 mm, para CIA 19.1 mm y para CIV 6.75 mm. Los dispositivos más utilizados fueron Amplatzer PDA y ASD, y Occlutech PDA. La tasa de éxito fue adecuada: PCA 95%, CIA 90% y CIV 75%. Reportamos una baja incidencia de complicaciones y generalmente menores, como shunt residual y hemólisis. Conclusiones: El manejo intervencionista de las cardiopatías congénitas con hiperflujo pulmonar es cada vez más frecuente con la disponibilidad de oclusores en nuestro medio, así como por el desarrollo de nuevos centros y el mayor entrenamiento de cardiólogos intervencionistas, lo que ha permitido mejores tasas de éxito y menor índice de complicaciones.

Abstract Introduction: In recent years, various occlusive devices have been developed that make it possible to avoid cardiac surgery in patients with congenital heart disease with pulmonary hyperflow. Objective: To describe the experience in percutaneous closure in heart disease with hyperflow. Material and methods: Through a descriptive, retrospective study, the medical records of patients undergoing cardiac intervention were reviewed, from 2016 to 2020. Results: Of 706 procedures performed in this time, 35% corresponded to various therapeutic cases. Of these, 189 corresponded to our series of operated patients with diagnoses of PDA (n = 164), ASD (n = 21) and VSD (n = 4). The clinical and demographic data were: in PDA 3.4 years (0.7-15) and 10.2 kg (6.1-46), in ASD 7.2 years (6-15) and 17.5 kg (15-38), and in VSD 7.25 years (6-9) and 20.75 kg (16-27). Regarding the size of the heart defects, the average was 4.3 mm PDA, 19.1 mm ASD and 6.75 mm VSD. The most used occluding devices were Amplatzer PDA and ASD, and Occlutech PDA. The success rate was adequate, PDA 95%, ASD 90% and VSD 75%. We report a low incidence of complications and generally minor ones such as residual shunt and hemolysis. Conclusions: The interventional management of the congenital heart diseases with pulmonary hyperflow is increasingly frequent with the availability of occlusive as well as the development of new centers and more training of interventional cardiologists, which has allowed better success rates and lower complication rate.

ABSTRACT Objective: To determine the clinical adverse events related to the use of femoral and radial artery access in patients who underwent interventional cardiology procedures in the Hospital Nacional Hipólito Unanue from 2015 to 2017. Materials and methods: A comparative, retrospective, observational and analytical study was conducted with a total of 151 medical records of patients who had clinical adverse events. Medical record review was used as data collection technique, and a data collection sheet designed by the researcher was used as instrument. The R software was used for the analysis. Results: Out of 151 cardiac catheterizations, 51.66 % were performed by a femoral artery access and 48.34 % by a radial artery access. The average age of the patients was 59.6 ± 11.3 years, out of which 39.73 % ranged between 60 and 70 years, and 73.50 % of the patients were males. The most frequent comorbidities were arterial hypertension and diabetes mellitus. Non-serious clinical adverse events occurred as a result of both vascular access procedures; however, their incidence was high. Fifty percent (50%) of the patients who underwent a femoral artery access procedure showed the following adverse events: hematoma (25.60 %), bleeding (9 %), ischemia (1.30 %), vagal response (1.30 %), pseudoaneurysm (1.30 %), a rare skin rash that looked like a burn (1.30 %) and pain (10.20 %). In contrast, 19.14 % of the patients who underwent a radial artery access procedure presented hematoma (8.21 %), bleeding (2.73 %), radial artery spasm (1.40 %) and pain (6.80 %). Conclusions: After determining the clinical adverse events, it was concluded that radial artery access is better than femoral artery access for interventional cardiology procedures.

Effectiveness of educational intervention with manual for anxiety and stress reduction: controlled clinical trial / Efectividad de la intervención educativa con manual para reducción de la ansiedad y estrés: ensayo clínico controlado / Efetividade da intervenção educativa com manual para redução da ansiedade e estresse: ensaio clínico controlado

ABSTRACT OBJECTIVE: To evaluate the effectiveness of the educational intervention through an informative manual in reducing anxiety, stress, and changes in vital signs in patients awaiting cardiac catheterization. METHODS: Parallel, randomized, controlled, blind clinical trial. The study excluded patients waiting for cardiac catheterization; those who received the information manual were randomized to the intervention group, and those who received routine information from the unit went to the control group. The study used the State Anxiety Inventory and Perceived Stress Scale and the ANOVA test to analyze the outcomes between the groups. Clinical Trials NCT03369873. RESULTS: There was no change concerning time, first and second moment (anxiety, P=0.225; and stress, P=0.696), interaction (anxiety, P=0.183; and stress, P=0.444), or groups, control, and intervention (anxiety, P=0.341; and stress, p=0.624). CONCLUSION: Although the educational intervention performed did not have an impact on the reduction of anxiety and stress, this type of intervention should be maintained for greater comfort and safety of patients and family members.

Feasibility of three-dimensional CT axial sequence assisted volumetric measurement for atrial septal defect evaluation / 中华放射学杂志

Objective:To explore the feasibility of three-dimensional CT axial sequence assisted volumetric measurement (CTAS) in evaluating atrial septal defect (ASD).Methods:The patients with single secundum ASD who successfully underwent interventional therapy in Fuwai Hospital from January 2016 to December 2019 were retrospectively collected. The patients underwent coronary CT angiography (CTA) before and on the second day after closures, and DSA examinations during operation. A total of 52 cases met the inclusion conditions, among them, there were 37 patients with large defects which had deficient inferior rims ≤3 mm, and 15 patients with severe pulmonary arterial hypertension that occluded with fenestrated ASD occluder. The CT data of patients before and after operation were reconstructed by CTAS. Then the anatomical structure of ASD before the operation was evaluated, including the long diameter and short diameter of ASD, and the CT three-dimensional volume diameter of ASD was calculated by using the equivalent circle conversion formula of ellipse. The waist diameter of occluder and rims of the ASD were measured after occlusion on postoperative CT three-dimensional volume reconstruction images. Meanwhile, the deployed occluder waist dimension was measured in DSA examination during the operation by simulating the balloon measurement of ASD. Lastly, paired t-test and consistency analysis were carried out among the values of parameters. Results:Before operation, the equivalent circle diameter of ASD was (32.3±5.4) mm measured by CTAS. After ASD occlusion, the size of the waist dimension measured by DSA and CTAS were (32.5±4.9) mm and (32.6±4.9) mm. There were no significant differences between them ( P>0.05). There were also no significant differences for each rims of the ASD pre and post operation on CTAS except for the inferior rims and the total length of atrial septum in superior-inferior direction ( P>0.05). Conclusion:As an alternative to balloon sizing, CTAS can be used as a reference standard to conduct ASD interventional treatment.

Early and Midterm Outcomes of "No-Touch" Saphenous Vein Grafts in Japanese Institutions

ABSTRACT Introduction: There have been several attempts to overcome the poor graft patency of saphenous vein grafts. "No-touch" saphenous vein graft (NT-SVG) could be a solution to improve graft patency. We aimed to investigate the early and midterm outcomes of coronary artery bypass grafting (CABG) using NT-SVGs in our hospitals. Methods: This is a retrospective study of 105 patients who underwent CABG using 130 NT-SVGs between August 2013 and December 2021. NT-SVGs were harvested with about a 5-mm margin of surrounding tissue on both sides of the vein with minimal manipulation. Then, the NT-SVG was dilated by natural arterial pressure without manual distension. After surgery, most of NT-SVGs were assessed by cardiac catheterization or multidetector computed tomography (MDCT) to determine early graft patency. Late graft assessments by MDCT were performed about every five years after surgery. Results: The early graft patency of NT-SVGs was 100% (125/125); however, two cases of graft twisting were found. Both cases spontaneously resolved. Leg wound infections of NT-SVG harvesting site were seen in 6.2% of patients. Peripheral neuropathy of the legs such as skin numbness and tingling were frequently observed, which lasted up to one year, but no more than two years after surgery. The midterm graft patency of NT-SVGs was excellent (five-year patency of NT-SVGs was 95.8%). Conclusion: The early and midterm graft patency of NT-SVGs was satisfactory. Although leg wound complications can be seen on the harvesting NT-SVG site, the "no-touch" harvesting technique of SVG could improve graft patency and clinical outcomes of CABG.
