      <title>Introdu&#231;&#227;o</title>
      <p>A pandemia de COVID-19 levou a uma importante ocupa&#231;&#227;o de leitos de terapia intensiva, causando a suspens&#227;o dos casos eletivos de cirurgia de revasculariza&#231;&#227;o do mioc&#225;rdio (CRM).</p>
      <p>Ao mesmo tempo, a evolu&#231;&#227;o de t&#233;cnicas de tratamento percut&#226;neo da doen&#231;a arterial coron&#225;ria (DAC) tem ampliado as possibilidades para essa modalidade, assim como estudos publicados n&#227;o demonstraram redu&#231;&#227;o de desfechos em pacientes est&#225;veis com carga isqu&#234;mica moderada/alta mantidos em tratamento cl&#237;nico otimizado (TCO).</p>
      <p>Neste contexto, todos os pacientes inclu&#237;dos em fila de CRM de um hospital terci&#225;rio de cardiologia tiveram suas indica&#231;&#245;es revisadas por um <italic>Heart Team</italic> (HT) com o intuito de avaliar uma poss&#237;vel mudan&#231;a de estrat&#233;gia para interven&#231;&#227;o coronariana percut&#226;nea (ICP) ou manuten&#231;&#227;o em TCO. Apresentamos as caracter&#237;sticas cl&#237;nicas e angiogr&#225;ficas, os motivos para mudan&#231;a da estrat&#233;gia terap&#234;utica, assim como a evolu&#231;&#227;o cl&#237;nica ap&#243;s um ano de seguimento.</p>

      <title>M&#233;todos</title>
      <p>Todos os pacientes inclu&#237;dos em uma fila de CRM entre junho de 2020 a abril de 2021 foram revistos por HT com especialistas s&#234;niores em cl&#237;nica, hemodin&#226;mica e cirurgia, com o intuito de avaliar mudan&#231;a de estrat&#233;gia de tratamento. Pacientes com estudo angiogr&#225;fico realizado h&#225; mais de um ano tiveram seu estudo repetido, assim como os de qualidade de imagem inadequada, ou na mudan&#231;a significativa da sintomatologia. Pacientes pouco sintom&#225;ticos ou com indica&#231;&#227;o de revasculariza&#231;&#227;o mioc&#225;rdica duvidosa foram submetidos a exames para quantifica&#231;&#227;o de &#225;rea isqu&#234;mica.</p>
      <p>Os pacientes que tiveram a indica&#231;&#227;o cir&#250;rgica modificada para outra modalidade de tratamento foram inclu&#237;dos nesse estudo. Eles foram analisados quanto &#224;s comorbidades, anatomia coronariana e risco cir&#250;rgico, assim como os motivos da mudan&#231;a do manejo e evolu&#231;&#227;o cl&#237;nica no primeiro ano. Os pacientes foram acompanhados por uma equipe dedicada ao estudo e mantidos em tratamento m&#233;dico otimizado.</p>
      <p>Em rela&#231;&#227;o aos desfechos cl&#237;nicos, avaliou-se a incid&#234;ncia de mortalidade por todas as causas, mortalidade cardiovascular, infarto agudo do mioc&#225;rdio (IAM), interna&#231;&#227;o por causa cardiovascular, sangramento relevante e acidente vascular cerebral.</p>

      <title>Resultados</title>
      <p>Dos 357 pacientes inclu&#237;dos em fila de CRM entre junho de 2020 a abril de 2021, 43 (12,0%) foram exclu&#237;dos pelo HT, sendo 21 submetidos a ICP e 22 mantidos em TCO. Os pacientes encaminhados a ICP tiveram maior preval&#234;ncia de diabetes (57,1% x 36,3%) e IAM pr&#233;vio (80,9% x 59%). Os mantidos em TCO tiveram maior preval&#234;ncia de AVC pr&#233;vio (13,6% x 0%) e maior risco cir&#250;rgico conforme o escore STS (1,12% X 0,68%). Cinco pacientes (11,6%) apresentavam sintomas limitantes: tr&#234;s em NYHA III foram mantidos em TCO, um pelo elevado risco cir&#250;rgico e outros dois por ter sido identificada doen&#231;a pulmonar obstrutiva cr&#244;nica como causa da dispneia; dois pacientes com angina CCS 3 foram encaminhados para ICP.</p>

        <p>Os pacientes tiveram seguimento m&#233;dio de 13 meses. Dois epis&#243;dios de IAM ocorreram entre pacientes encaminhados para realiza&#231;&#227;o de ICP, e resultaram em &#243;bito: uma mulher apresentou morte s&#250;bita precedida de precordialgia t&#237;pica antes da realiza&#231;&#227;o da ICP e um homem apresentou IAM periprocedimento evoluindo com choque cardiog&#234;nico refrat&#225;rio. Os demais pacientes n&#227;o apresentaram eventos cardiovasculares maiores.</p>

      <p>Devido &#224; importante redu&#231;&#227;o do n&#250;mero de cirurgias durante a pandemia de COVID-19, causada pela falta de leitos de UTI e afastamento dos servidores hospitalares<sup><xref ref-type="bibr" rid="B1">1</xref>,<xref ref-type="bibr" rid="B2">2</xref></sup> foi necess&#225;ria a revis&#227;o da lista de CRM. O risco de infec&#231;&#227;o intra-hospitalar tamb&#233;m foi relevante, por aumentar significativamente a morbimortalidade.<sup><xref ref-type="bibr" rid="B3">3</xref>,<xref ref-type="bibr" rid="B4">4</xref></sup> Baseado em diretrizes internacionais, o HT modificou a estrat&#233;gia de tratamento de 12% dos pacientes, que foram acompanhados por um ano.</p>
      <p>Alguns dos pacientes inclu&#237;dos no nosso estudo apresentavam indica&#231;&#227;o mais sedimentada de revasculariza&#231;&#227;o cir&#250;rgica.<sup><xref ref-type="bibr" rid="B5">5</xref>-<xref ref-type="bibr" rid="B8">8</xref></sup> Contudo, considerando o risco de um tempo indeterminado, a espera do tratamento cir&#250;rgico e a expertise da equipe de cardiologia intervencionista do nosso servi&#231;o, o HT optou pela mudan&#231;a no tratamento.</p>
      <p>Estudos recentes corroboram essa ideia. Uma coorte de 215 pacientes de 45 centros do Reino Unido, inicialmente inclu&#237;dos em fila de CRM, foi submetida &#224; ICP em fun&#231;&#227;o do longo tempo de espera. No seguimento de 30 dias, apresentaram desfechos cl&#237;nicos semelhantes aos tradicionalmente encontrados em pacientes submetidos &#224; CRM.<sup><xref ref-type="bibr" rid="B9">9</xref></sup>O fato dos desfechos do TCO serem compar&#225;veis aos do tratamento invasivo em pacientes est&#225;veis com carga isqu&#234;mica relevante<sup><xref ref-type="bibr" rid="B10">10</xref></sup> foi importante para mudan&#231;a da estrat&#233;gia nesse grupo.</p>
      <p>A relev&#226;ncia do trabalho em equipe no manejo da DAC complexa tem sido demonstrada.<sup><xref ref-type="bibr" rid="B11">11</xref>,<xref ref-type="bibr" rid="B12">12</xref></sup>As recomenda&#231;&#245;es de tratamento da DAC multiarterial do cardiologista intervencionista isoladamente e do HT s&#227;o discordantes em um n&#250;mero significativo de casos.<sup><xref ref-type="bibr" rid="B13">13</xref></sup> Al&#233;m disso, seguimentos de longo prazo de pacientes cuja estrat&#233;gia de tratamento foi definida por HT tem demonstrado tomadas de decis&#227;o apropriadas e personalizadas, com desfechos favor&#225;veis.<sup><xref ref-type="bibr" rid="B14">14</xref></sup></p>
      <p>Nosso estudo tem diversas limita&#231;&#245;es. O n&#250;mero limitado de pacientes inclu&#237;dos em nosso estudo pode restringir a generaliza&#231;&#227;o dos dados. Entretanto, listas cir&#250;rgicas devem ser idealmente pequenas, para n&#227;o permitir tempo prolongado de espera. Um maior tempo de seguimento desses pacientes poderia trazer resultados mais fidedignos a respeito dos desfechos encontrados. Estudos multic&#234;ntricos com amostras maiores e desenhos adequados s&#227;o necess&#225;rios para elucidar o real impacto da exclus&#227;o de pacientes da fila de CRM por HT com base nas atuais evid&#234;ncias dispon&#237;veis.</p>
      <p>No presente estudo, a reavalia&#231;&#227;o de pacientes em fila de CRM por HT durante a pandemia da COVID-19 permitiu a redu&#231;&#227;o de 12% do n&#250;mero de indica&#231;&#245;es de tratamento cir&#250;rgico, sendo poss&#237;vel a mudan&#231;a para TCO ou ICP, de acordo com recentes diretrizes e estudos. Entre os pacientes que tiveram sua estrat&#233;gia terap&#234;utica modificada, observamos uma excelente sobrevida livre de eventos em um ano.</p>

        <title>Introduction</title>
        <p>The COVID-19 pandemic led to a significant occupation of intensive care beds, causing the suspension of elective cases of coronary artery bypass grafting (CABG).</p>
        <p>At the same time, the evolution of techniques for the percutaneous treatment of coronary artery disease (CAD) has expanded the possibilities for this modality, and published studies have not shown a reduction in outcomes in stable patients with moderate/high ischemic burden under optimized clinical treatment (OCT).</p>
        <p>In this context, all patients included in the CABG queue of a tertiary cardiology hospital had their indications reviewed by a Heart Team (HT) in order to assess a possible change in strategy for percutaneous coronary intervention (PCI) or maintenance on OCT. We present the clinical and angiographic characteristics, the reasons for changing the therapeutic strategy, as well as the clinical evolution after one year of follow-up.</p>
      </sec>
      <sec sec-type="methods">
        <title>Methods</title>
        <p>All patients included in a CABG queue between June 2020 and April 2021 were reviewed by a HT with senior clinical, hemodynamics and surgery specialists in order to assess change in treatment strategy. Patients with an angiographic study performed more than one year prior had their study repeated, as well as those with poor image quality, or significant change in symptomatology. Patients with few symptoms or with doubtful indication of coronary artery bypass grafting were tested to quantify the ischemic area.</p>
        <p>Patients whose surgical indication was changed to another treatment modality were included in this study. They were examined for comorbidities, coronary anatomy and surgical risk, as well as the reasons for the change in management and clinical evolution in the first year. Patients were followed up by a team dedicated to the study and maintained on optimal medical treatment.</p>
        <p>Regarding clinical outcomes, the incidence of all-cause mortality, cardiovascular mortality, acute myocardial infarction (AMI), hospitalization for cardiovascular causes, relevant bleeding, and stroke was evaluated.</p>

        <title>Results</title>
        <p>Of the 357 patients included in the CRM queue between June 2020 and April 2021, 43 (12.0%) were excluded by the HT, with 21 undergoing PCI and 22 maintained on OCT. Patients referred for PCI had a higher prevalence of diabetes (57.1% vs. 36.3%) and previous AMI (80.9% vs. 59%). Those maintained on OCT had a higher prevalence of previous stroke (13.6% vs. 0%) and higher surgical risk according to the STS score (1.12% vs. 0.68%). Five patients (11.6%) had limiting symptoms: three in NYHA III were maintained on OCT, one because of the high surgical risk and the other two because chronic obstructive pulmonary disease was identified as the cause of dyspnea; two patients with CCS 3 angina were referred for PCI.</p>

        <title>Discussion</title>
        <p>Due to the significant reduction in the number of surgeries during the COVID-19 pandemic, caused by the lack of ICU beds and the number of hospital personnel on leave,<sup><xref ref-type="bibr" rid="B1">1</xref>,<xref ref-type="bibr" rid="B2">2</xref></sup> revision of the CABG waiting list was necessary. The risk of in-hospital infection was also relevant, as it significantly increased morbidity and mortality.<sup><xref ref-type="bibr" rid="B3">3</xref>,<xref ref-type="bibr" rid="B4">4</xref></sup> Based on international guidelines, the HT changed the treatment strategy of 12% of patients, who were followed up for one year.</p>
        <p>Some of the patients included in our study had a more solid indication for coronary artery bypass grafting.<sup><xref ref-type="bibr" rid="B5">5</xref>-<xref ref-type="bibr" rid="B8">8</xref></sup> However, considering the risk of an indefinite period of time, the wait for surgical treatment and the expertise of the interventional cardiology team at our service, the HT opted for a change in treatment.</p>
        <p>Recent studies corroborate this idea. A cohort of 215 patients from 45 centers in the United Kingdom, initially included in the CABG waiting list, underwent PCI due to the long waiting time. In the 30-day follow-up, they presented clinical outcomes similar to those traditionally found in patients undergoing CABG.<sup><xref ref-type="bibr" rid="B9">9</xref></sup></p>
        <p>The fact that OCT outcomes were comparable to those of invasive treatment in stable patients with relevant ischemic burden<sup><xref ref-type="bibr" rid="B10">10</xref></sup> was important for changing the strategy in this group.</p>
        <p>The relevance of teamwork in the management of complex CAD has been demonstrated.<sup><xref ref-type="bibr" rid="B11">11</xref>,<xref ref-type="bibr" rid="B12">12</xref></sup> Treatment recommendations for multivessel CAD by the interventional cardiologist alone and by the HT are in disagreement in a significant number of cases.<sup><xref ref-type="bibr" rid="B13">13</xref></sup> Furthermore, long-term follow-up of patients whose treatment strategy was defined by the HT has demonstrated appropriate and personalized decision-making, with favorable outcomes.<sup><xref ref-type="bibr" rid="B14">14</xref></sup></p>
        <p>Our study has several limitations. The limited number of patients included in our study may restrict data generalizability. However, surgery waiting lists should ideally be short to avoid long waiting times. A longer follow-up time for these patients could bring more reliable results regarding the outcomes found. Multicentric studies with larger samples and adequate designs are needed to elucidate the real impact of HT exclusion of patients from the CABG waiting list based on the current available evidence.</p>
        <p>In this study, the reassessment of patients queuing for CABG due to HT during the COVID-19 pandemic allowed a 12% reduction in the number of surgery indications, making it possible to switch to OCT or PCI, according to the latest guidelines and studies. Among patients who had their therapeutic strategy modified, we observed excellent event-free survival at one year.</p>
