A Coronary Artery Anomaly Presenting as Acute Coronary Syndrome: A Case Report.

BACKGROUND Coronary artery anomalies (CAAs) are rare congenital malformations with different clinical presentations and pathophysiological mechanisms. These anomalies are frequently the cause of sudden death in young patients. Most CAAs are incidental findings owing to the lack of symptoms; however, they may be associated with acute coronary syndrome in rare cases. CASE REPORT We describe the case of a 47-year-old man who presented with a 1-day history of progressive typical chest pain and elevated troponin levels. The patient underwent a coronary angiography, which unveiled the anomalous origin of the left main coronary artery arising from the right coronary artery, with an interarterial course between the ascending aorta and the pulmonary artery, without coronary artery disease. Coronary computed tomography angiography confirmed the CAA and its relationship with the symptoms. An uneventful coronary artery bypass graft was undertaken, and at the 1-year follow-up, the patient was asymptomatic, with a normal stress test. CONCLUSIONS This case depicts the presentation of atypical acute coronary syndrome in a young patient with a rare CAA. In such patients, coronary angiography and coronary computed tomography angiography are essential tools to confirm the diagnosis and to determine treatment. Although controversial, in young individuals presenting CAA with an interarterial course, such as the left main coronary artery arising from the right coronary artery, coronary artery bypass graft may be an important treatment option to avoid sudden death in the future.

Safe and effective protocol for discharge 3 days after cardiac surgery.

The Enhanced Recovery After Surgery (ERAS) protocol affected traditional cardiac surgery processes and COVID-19 is expected to accelerate its scalability. The aim of this study was to assess the impact of an ERAS-based protocol on the length of hospital stay after cardiac surgery. From January 2019 to June 2020, 664 patients underwent consecutive cardiac surgery at a Latin American center. Here, 46 patients were prepared for a rapid recovery through a multidisciplinary institutional protocol based on the ERAS concept, the "TotalCor protocol". After the propensity score matching, 46 patients from the entire population were adjusted for 12 variables. Patients operated on the TotalCor protocol had reduced intensive care unit time (P < 0.025), postoperative stay (P ≤ 0.001) and length of hospital stay (P ≤ 0.001). In addition, there were no significant differences in the occurrence of complications and death between the two groups. Of the 10-central metrics of TotalCor protocol, 6 had > 70% adherences. In conclusion, the TotalCor protocol was safe and effective for a 3-day discharge after cardiac surgery. Postoperative atrial fibrillation and renal failure were predictors of postoperative stay > 5 days.

Improvement in quality indicators using NCDR® registries: First international experience.

BACKGROUND: The National Cardiovascular Data Registry (NCDR®) Database is commonly used for quality-improvement initiatives in North America, but little is known about the application of this tool in other regions of the world. METHODS: All consecutive patients admitted due to myocardial infarction (MI) and/or undergoing percutaneous coronary intervention (PCI) from January 2012 until December 2015 in a Brazilian private cardiovascular hospital were included respectively in ACTION REGISTRY®-GWTG™ and CathPCI Registry®. Meetings including all hospital staff were performed quarterly to discuss every NCDR® report. Quality improvement initiatives were developed based on the reports which were also used for evaluation of changes after the interventions. The following indicators were considered a priority 1) Door-to-ECG and door-to-balloon (D2B) times; 2) PCI appropriateness; 3) length of stay; 4) delivery of guideline-based medication. Changes in the quality of care with respect to the over time were assessed using linear and logistic regression for continuous and binary outcomes, respectively. RESULTS: A total of 1.382 patients were included in the ACTION REGISTRY®-GWTG™ and 3.179 patients in the CathPCI Registry®. In the ACTION registry, the overall AMI performance composite of quality indicators improved along the 4 years from 95.0% to 99.6% (p for trend <0.001). The percentage of appropriate/uncertain PCI in acute and elective scenario increased along the years from 91.1% and 70.9% to 96.6% and 84.7%, respectively (p for trend <0.001). CONCLUSION: The present novel experience using the NCDR® registries as benchmarks to guide quality-improvement programs in an international site was associated with improvement in quality indicators.

Impact of Chest Pain Protocol with Access to Telemedicine on Implementation of Pharmacoinvasive Strategy in a Private Hospital Network.

BACKGROUND: Brazilian registries have shown a gap between evidence-based therapies and real treatments. We aim to compare the use of the pharmacoinvasive strategy and mortality in patients with ST elevation myocardial infarction (STEMI) transferred pre- and post-chest pain protocol with access to telemedicine (CPPT) in a private hospital network. MATERIALS AND METHODS: A CPPT was implemented in 22 private emergency departments in 2012. Emergency physicians and nurses of all facilities were trained to disseminate the information to comply with a chest pain protocol focusing on reperfusion therapy (pharmacoinvasive strategy) for STEMI. To conduct clinical discussions using telemedicine, a cardiologist from a reference hospital in cardiology (RHC) was available 24 h/day, 7 days/week. Using the database of all consecutive admissions, we compared the data of patients with STEMI transferred to the RHC in 2011 (pre-CPPT) and 2013-2014 (post-CPPT). RESULTS: We included 376 patients (113 pre-CPPT and 263 post-CPPT) with STEMI. All patients admitted in the RHC were transferred from the 22 emergency departments. Comparing pre-CPPT and post-CPPT, we did not find differences regarding age, gender, hypertension, dyslipidemia, diabetes, smoking, previous myocardial infarction, or Killip classification. However, the use of CPPT was associated with a greater use of pharmacoinvasive strategy (55.8% versus 38%; p = 0.002) and a trend toward lower in-hospital mortality (3% versus 8%; p = 0.06). CONCLUSIONS: The implementation of a CPPT was associated with a significant increase in the use of pharmacoinvasive strategy in patients with STEMI and a trend toward reduced in-hospital mortality in a private hospital network.

Improving Indicators in a Brazilian Hospital Through Quality-Improvement Programs Based on STS Database Reports

ABSTRACT OBJECTIVE: To report the initial changes after quality-improvement programs based on STS-database in a Brazilian hospital. METHODS: Since 2011 a Brazilian hospital has joined STS-Database and in 2012 multifaceted actions based on STS reports were implemented aiming reductions in the time of mechanical ventilation and in the intensive care stay and also improvements in evidence-based perioperative therapies among patients who underwent coronary artery bypass graft surgeries. RESULTS: All the 947 patients submitted to coronary artery bypass graft surgeries from July 2011 to June 2014 were analyzed and there was an improvement in all the three target endpoints after the implementation of the quality-improvement program but the reduction in time on mechanical ventilation was not statistically significant after adjusting for prognostic characteristics. CONCLUSION: The initial experience with STS registry in a Brazilian hospital was associated with improvement in most of targeted quality-indicators.

Evaluation of the Society of Thoracic Surgeons score system for isolated coronary bypass graft surgery in a Brazilian population.

OBJECTIVE: Report the experience with the Society of Thoracic Surgeons scoring system in a Brazilian population submitted to isolated coronary artery bypass graft surgery. METHODS: Data were collected from January-2010 to December-2011, and analyzed to determine the performance of the Society of Thoracic Surgeons scoring system on the determination of postoperative mortality and morbidity, using the method of the receiver operating characteristic curve as well as the Hosmer-Lemeshow and the Chi-square goodness of fit tests. From the 1083 cardiac surgeries performed during the study period 659 represented coronary artery bypass graft procedures which are included in the present analysis. Mean age was 61.4 years and 77% were men. RESULTS: Goodness of fit tests have shown good calibration indexes both for mortality (X2=6.78, P=0.56) and general morbidity (X2=6.69, P=0.57). Analysis of area under the ROC-curve (AUC) demonstrated a good performance to detect the risk of death (AUC 0.76; P<0.001), renal failure (AUC 0.79; P<0.001), prolonged ventilation (AUC 0.80; P<0.001), reoperation (AUC 0.76; P<0.001) and major morbidity (AUC 0.75; P<0.001) which represents the combination of the assessed postoperative complications. STS scoring system did not present comparable results for short term hospital stay, prolonged length of hospital stay and could not be properly tested for stroke and wound infection. CONCLUSION: Society of Thoracic Surgeons scoring system presented a good calibration and discrimination in our population to predict postoperative mortality and the majority of the harmful events following coronary artery bypass graft surgery. Analysis of larger samples might be needed to further validate the use of the score system in Brazilian populations.

Implementation of an institutional protocol for rational use of blood products and its impact on postoperative of coronary artery bypass graft surgery.

OBJECTIVE: Cardiac surgeries are sometimes followed by significant blood loss, and blood transfusions may be necessary. However, indiscriminant use of blood components can result in detrimental effects for the patient. We evaluated the short-term effects of implementation of a protocol for the rational use of blood products in the perioperative period of cardiac surgery. METHODS: Between April and June 2011, an institutional protocol was implemented in a private hospital specializing in cardiology to encourage rational use of blood products, with the consent and collaboration of seven cardiac surgery teams. We collected clinical and demographic data on the patients. The use of blood products and clinical outcomes were analyzed during hospital stay before and after protocol implementation. The protocol consisted of an institutional campaign with an educational intervention to surgical and anesthesiology teams; the goal was to tailor blood transfusion practice according to clinical goals (anemia with hemodynamic changes and significant ventricular dysfunction) and to make routine the prescription of ε-aminocaproic acid intraoperatively, which is recommended by international guidelines based on scientific evidence. RESULTS: After three months of protocol implementation, the use of ε-aminocaproic acid increased from 31% to 100%. A total of 67% of surgeries before protocol implementation required any blood transfusion, compared with 40% that required any blood transfusion after protocol implementation in subsequent months of the same year (p<0.001). There was no significant difference in clinical outcomes assessed before and after implementation of the protocol. CONCLUSION: The rational use of blood products associated with infusion of ε-aminocaproic acid has the potential to reduce the number of blood transfusions in perioperative of cardiac surgeries, but it can affect the risk of complications.

Implantação de protocolo institucional para o uso racional de hemoderivados e seu impacto no pós-operatório de cirurgias de revascularização miocárdica / Implementation of an institutional protocol for rational use of blood products and its impact on postoperative of coronary artery bypass graft surgery

OBJETIVO: Cirurgias cardíacas são, por vezes, acompanhadas de perdas sanguíneas significativas, e transfusões de sangue podem ser necessárias. No entanto, o uso indiscriminado de hemoderivados pode resultar em efeitos danosos para o paciente. Neste estudo, avaliamos os efeitos imediatos da implantação de um protocolo para o uso racional de hemoderivados no perioperatório de cirurgias de revascularização miocárdica. MÉTODOS: Entre os meses de abril e junho de 2011, foi implementado um protocolo institucional em um hospital privado especializado em cardiologia com a anuência e a colaboração de sete equipes de cirurgia cardíaca, visando ao uso racional de hemoderivados. Foram verificados dados clínicos e demográficos dos pacientes, e avaliados o uso de hemoderivados e os desfechos clínicos no período intra-hospitalar, antes e após a implantação do protocolo. O protocolo consistiu em uma campanha institucional junto às equipes cirúrgicas, de anestesiologia e intensivistas, para difundir a prática do uso de hemoderivados com base em critérios clínicos objetivos (anemia com repercussões hemodinâmicas e disfunção ventricular significativa), bem como tornar rotineira a prescrição de ácido epsilon-aminocaproico no intraoperatório, que é prática recomendada por diretrizes internacionais baseadas em evidência científica. RESULTADOS: Após os 3 meses de implantação do protocolo, houve aumento do uso de ácido epsilon-aminocaproico de 31% para 100%. Antes da implantação do protocolo, 67% das cirurgias utilizaram alguma transfusão sanguínea; após a implantação, 40% das cirurgias necessitaram de alguma transfusão sanguínea nos meses subsequentes do mesmo ano (p<0,001). Não houve diferença significativa nos desfechos clínicos avaliados antes e após implantação do protocolo. CONCLUSÃO: O uso racional de hemoderivados, associado à infusão do ácido epsilon-aminocaproico, tem o potencial de reduzir o número de hemotransfusões no perioperatório de cirurgias cardíacas...

The protocol consisted of an institutional campaign with an educational intervention to surgical and anesthesiology teams; the goal was to tailor blood transfusion practice according to clinical goals (anemia with hemodynamic changes and significant ventricular dysfunction) and to make routine the prescription of å-aminocaproic acid intraoperatively, which is recommended by international guidelines based on scientific evidence. RESULTS: After three months of protocol implementation, the use of å-aminocaproic acid increased from 31% to 100%. A total of 67% of surgeries before protocol implementation required any blood transfusion, compared with 40% that required any blood transfusion after protocol implementation in subsequent months of the same year (p<0.001). There was no significant difference in clinical outcomes assessed before and after implementation of the protocol. CONCLUSION: The rational use of blood products associated with infusion of å-aminocaproic acid has the potential to reduce the number of blood transfusions in perioperative of cardiac surgeries, but it can affect the risk of complications.

Comparação das vias radial e femoral nas intervenções coronárias percutâneas: resultados do registro TotalCor / Comparison of radial vs. femoral access in percutaneous coronary interventions: outcomes of the TotalCor registry

Introdução: A intervenção coronária percutânea (ICP) por via radial ainda é pouco utilizada em nosso meio. O objetivo do presente estudo foi avaliar a prevalência e os resultados da ICP por via radial, comparada à via femoral, em uma população do mundo real. Métodos: Registro unicêntrico, com 507 pacientes consecutivos submetidos a ICP pelas vias radial (n = 121) e femoral (n = 386), de acordo com a escolha do operador. Resultados: Os pacientes que utilizaram a via radial (23,9%) eram mais frequentemente do sexo masculino (78,5% vs. 69,9%; P = 0,07) e tabagistas (19,8% vs. 11,7%; P = 0,02), com maior prevalência de lesões uniarteriais (59,5% vs. 46,4%), tipo A/B1 (39% vs. 28,4%) e com função ventricular preservada (87,1% vs. 73%; P < 0,01). Nesse grupo foram utilizados stents de maior diâmetro e menor comprimento. O sucesso do procedimento foi elevado (97,3% vs. 96,3%; P = 0,56) e a incidência de óbito foi baixa, não diferindo entre os grupos (0,8% vs. 0,8%; P = 0,96), assim como as taxas de infarto do miocárdio (2,5% vs. 2,1%; P = 0,73). Não ocorreram revascularizações do vaso-alvo de urgência. Os pacientes tratados pela via radial permaneceram menos tempo internados (1 dia vs. 2 dias; P = 0,02) e não apresentaram complicações vasculares (0 vs. 3,4%; P = 0,045). Conclusões: A utilização da ICP por via radial representa o dobro da média nacional na instituição em que o estudo foi realizado, e a escolha de pacientes para essa técnica trouxe resultados do procedimento equivalentes aos da via femoral, nenhuma complicação vascular, e reduziu à metade o tempo de internação hospitalar.

BACKGROUND: In our country radial access is still underused in percutaneous coronary interventions (PCI). The objective of this study was to evaluate the prevalence and compare radial to femoral vascular access for PCI in a real-world population. METHODS: Single center registry, with 507 consecutive patients undergoing PCI by radial (n = 121) and femoral (n = 386) access, according to the operator's choice. RESULTS: Patients using radial access (23.9%) were more often male (78.5% vs. 69.9%; P = 0.07) and smokers (19.8% vs. 11.7%; P = 0.02), had a higher prevalence of single-vessel disease (59.5% vs. 46.4%), type A/B1 (39% vs. 28.4%) lesions and had preserved ventricular function (87.1% vs. 73%; P < 0.01). Larger diameter and shorter stents were used in this group. Procedure success was high (97.3% vs. 96.3%; P = 0.56), the incidence of death was low and was not different between groups (0.8% vs. 0.8%; P = 0.96), as well as myocardial infarction rates (2.5% vs. 2.1%; P = 0.73). There were no urgent target-vessel revascularizations. Patients treated by the radial approach had a shorter hospitalization period (1 day vs. 2 days; P = 0.02) and did not have vascular complications (0 vs. 3.4%; P = 0.045). CONCLUSIONS: The use of radial access for PCI in our institution is twice the national average and the choice of patients for this technique provided similar results to those obtained by the femoral approach, no vascular complications and halved patients' average stay in hospital.
