      <p>Bioresorbable vascular scaffolds (BVS) demonstrate favourable outcomes in patients with

            considered the "fourth revolution" in percutaneous coronary intervention (PCI)
            technology. BVS represent a promising alternative to drug-eluting stents (DES) while
            offering the same advantages. We present the first case of in-stent restenosis (ISR)
            successfully treated with an everolimus-eluting BVS (ABSORB; Abbott Vascular, Santa
            Clara, CA) and discuss its potential advantages in such lesion.</p>

      <title>Case Report</title>
      <p>A 72-year-old male presented with a 3-week history of relapsing Canadian Cardiovascular
            Society class 3/4 angina. He had undergone PCI of the proximal left anterior descending
            (LAD) 4 years prior using a 2.75 x 18 mm sirolimus-eluting stent (Cypher Cordis, Miami,
            FL). His medical regimen included aspirin and a statin. Resting ECG and cardiac
            biomarkers were normal. Given the severity of his symptoms and his past medical history,
            it was decided to proceed directly to coronary angiography.</p>
      <p>The coronary angiogram showed a severe 95% ISR lesion of the proximal LAD with thrombus
            and multiple areas of contrast staining outside the stent contour, compatible with
            coronary micro-aneurysms (<xref ref-type="fig" rid="f01">Figure 1A</xref>).
            Thromboaspiration revealed white thrombus. Optical coherence tomography (OCT) was
            compatible with a localized hypersensitivity reaction to first-generation DES (<xref ref-type="fig" rid="f01">Figure 1B</xref>). After consensus with the referring
            physician, an ABSORB everolimus-eluting BVS 3.0 x 18 mm was deployed (<xref ref-type="fig" rid="f02">Figure 2A</xref>). Repeated OCT showed good scaffold
            apposition and coverage of the micro-aneurysms (<xref ref-type="fig" rid="f02">Figure
               2B</xref>). The patient was discharged the following day on dual antiplatelet therapy
            with aspirin and ticagrelor. The patient was asymptomatic at 6 months clinical
            follow-up.</p>

      <title>Discussion</title>
      <p>To the best of our knowledge, this is the first report describing the use of a BVS in a
            case of ISR and late acquired malapposition secondary to first-generation DES. The
            ABSORB BVS consists of resorbable polymers containing the antiproliferative drug
            everolimus. Prospective studies of BVS showed favourable outcomes in simple, de novo
            coronary lesions<xref ref-type="bibr" rid="B01">1</xref><sup>,</sup><xref ref-type="bibr" rid="B02">2</xref>, with long-term positive vessel remodelling, late
            lumen enlargement, complete resorption of the vascular scaffold, and progressive filling
            of the previously occupied space with proteoglycans at follow-up<xref ref-type="bibr" rid="B03">3</xref>. However, these studies specifically excluded ISR lesions.</p>
      <p>In the current report, a local delayed hypersensitivity vasculitis caused by a
            sirolimus-eluting stent was suspected to be the causal mechanism leading to late
            acquired stent malapposition, restenosis, with superimposed very late thrombosis<xref ref-type="bibr" rid="B04">4</xref>. Typical angiographic findings present in our
            patient, including positive remodelling and micro-aneurysms of the mid-segment of the
            stent. This hypersensitivity reaction has been attributed to the polymer coating of
            sirolimus-eluting stents, which, importantly, differs from the one used in the ABSORB
               BVS<xref ref-type="bibr" rid="B04">4</xref>.</p>
      <p>In this particular case, the use of BVS had several advantages: avoidance of
            accumulation of multiple layers of metallic stent, avoidance of re-exposure to the same
            "allergic antigen" and most importantly, hypothetically, the healing process of BVS
            characterized by late lumen enlargement and replacement of the platform by
            proteoglycans, resulting in filling of the micro-aneurysms and exclusion of the nidus
            involved in the genesis of neo-thrombi. Angiographic follow-up with OCT imaging at 2
            years or beyond will potentially validate the latest hypothesis.</p>

      <title>Conclusion</title>
      <p>BVS are a promising addition to the PCI arsenal in managing complex coronary lesions.
            This case report demonstrates novel use of this technology to treat an ISR lesion of DES
            characterized by late acquired malapposition.</p>

        <p>Os dispositivos vasculares biorreabsorv&#237;veis (DVR) demonstram resultados favor&#225;veis
               em pacientes com doen&#231;a coronariana est&#225;vel com les&#245;es de novo coronarianas simples
               (1, 2) e s&#227;o considerados a "quarta revolu&#231;&#227;o" na tecnologia de interven&#231;&#227;o coron&#225;ria
               percut&#226;nea (ICP). Os DVR representam uma alternativa promissora aos
                  <italic>stents</italic> farmacol&#243;gicos (SLF), oferecendo as mesmas vantagens.
               Apresentamos o primeiro caso de reestenose intra-stent (RIS) tratado com sucesso com
               um DVR liberador de everolimus (ABSORB; Abbott Vascular, Santa Clara, CA) e

        <title>Relato de Caso</title>
        <p>Um homem de 72 anos apresentou-se com uma hist&#243;ria de 3 semanas de reca&#237;da de angina
               classe 3/4 da Canadian Cardiovascular Society. Tinha sido submetido &#224; ICP da
               descendente anterior esquerda proximal (DAE) 4 anos antes usando um
                  <italic>stent</italic> liberador de sirolimus de 2,75 x 18 mm (Cypher Cordis,
               Miami, FL). Seu regime m&#233;dico inclu&#237;a aspirina e estatina. O ECG de repouso e os
               biomarcadores card&#237;acos eram normais. Dada a gravidade dos seus sintomas e sua
               hist&#243;ria m&#233;dica passada, decidiu-se proceder diretamente &#224; angiografia coronariana. A
               coronariografia mostrou uma severa RIS de 95% da DAE proximal com trombo e m&#250;ltiplas
               &#225;reas de colora&#231;&#227;o de contraste fora do contorno do <italic>stent</italic>,
               compat&#237;vel com micro-aneurismas coron&#225;rios (<xref ref-type="fig" rid="f03">Figura
                  1A</xref>). A tromboaspira&#231;&#227;o revelou trombo branco. A tomografia de coer&#234;ncia
               &#243;ptica (TCO) era compat&#237;vel com uma rea&#231;&#227;o de hipersensibilidade localizada a SLF de
               primeira gera&#231;&#227;o (<xref ref-type="fig" rid="f03">Figura 1B</xref>). Depois de
               consenso com seu m&#233;dico de refer&#234;ncia, foi implantado um DVR ABSORB de 3,0 x 18 mm
               liberador de everolimus (<xref ref-type="fig" rid="f04">Figura 2A</xref>). TCOs
               repetidas mostraram boa aposi&#231;&#227;o do dispositivo e cobertura dos micro-aneurismas
                  (<xref ref-type="fig" rid="f04">Figura 2B</xref>). O paciente recebeu alta no dia
               seguinte com terapia antiplaquet&#225;ria dupla com aspirina e ticagrelor. O paciente
               encontrava-se assintom&#225;tico ap&#243;s 6 meses de acompanhamento cl&#237;nico.</p>

        <title>Discuss&#227;o</title>
        <p>At&#233; onde sabemos, este &#233; o primeiro relat&#243;rio que descreve o uso de um DVR em um caso
               de RIS e m&#225; aposi&#231;&#227;o tardia adquirida secund&#225;ria a SLF de primeira gera&#231;&#227;o. O DVR
               ABSORB est&#225; composto por pol&#237;meros reabsorv&#237;veis que cont&#233;m a droga antiproliferativa
               everolimus. Estudos prospectivos de DVR mostraram resultados favor&#225;veis em les&#245;es de
               novo coronarianas simples<xref ref-type="bibr" rid="B01">1</xref><sup>,</sup><xref ref-type="bibr" rid="B02">2</xref>, com remodela&#231;&#227;o positiva de longo prazo do
               vaso, alargamento tardio do l&#250;men, reabsor&#231;&#227;o completa do dispositivo vascular, e
               enchimento progressivo do espa&#231;o previamente ocupado com proteoglicanos no
                  seguimento<xref ref-type="bibr" rid="B03">3</xref>. No entanto, esses estudos
               exclu&#237;ram especificamente les&#245;es de RIS.</p>
        <p>No presente relat&#243;rio, se suspeitou que uma vasculite local de hipersensibilidade
               retardada causada por um <italic>stent</italic> liberador de sirolimus era o
               mecanismo causal que conduziu a m&#225; aposi&#231;&#227;o tardia do <italic>stent</italic> e
               reestenose, com trombose tardia sobreposta<xref ref-type="bibr" rid="B04">4</xref>.
               Achados angiogr&#225;ficos t&#237;picos estes, presentes em nosso paciente, incluindo a
               remodela&#231;&#227;o positiva e micro-aneurismas do segmento m&#233;dio do <italic>stent</italic>.
               Esta rea&#231;&#227;o de hipersensibilidade tem sido atribu&#237;da ao revestimento de pol&#237;mero de
                  <italic>stents</italic> liberadores de sirolimus, que, significativamente, &#233;
               diferente do utilizado no DVR ABSORB<xref ref-type="bibr" rid="B04">4</xref>.</p>
        <p>Neste caso em particular, o uso do DVR teve v&#225;rias vantagens: evitar a acumula&#231;&#227;o de
               m&#250;ltiplas camadas de <italic>stent</italic> met&#225;lico, evitar a re-exposi&#231;&#227;o ao mesmo
               "ant&#237;geno alerg&#234;nico" e, mais importante, hipoteticamente, o processo de cicatriza&#231;&#227;o
               do DVR caracterizado por alargamento tardio do l&#250;men e substitui&#231;&#227;o da plataforma de
               proteoglicanos, resultando em enchimento dos micro-aneurismas e exclus&#227;o do foco
               envolvido na g&#234;nese dos neo-trombos. O seguimento angiogr&#225;fico com TCO de imagem em 2
               anos ou mais, potencialmente validar&#225; esta &#250;ltima hip&#243;tese.</p>

        <p>O DVR &#233; uma incorpora&#231;&#227;o promissora para o arsenal de ICP na gest&#227;o de les&#245;es
