    <p>This was an 84-year-old male patient, with worsening functional class from NYHA III/IV to IV/IV and palpitations. No syncope. Physical examination revealed bradycardia, the rest was uneventful. Electrocardiogram showed Mobitz II atrioventricular block. Patient was scheduled for permanent pacemaker implantation.</p>
    <p>Subclavian vein access was performed via direct puncture. The guide wire was advanced, entered the subclavian vein and descended parallel to the spine without crossing over to the right side. Subsequently, the guide wire traversed the coronary sinus and ended in the right atrium. Persistent left superior vena cava was diagnosed. During fluoroscopic observation, another feature that aids in the diagnosis is left paravertebral shadow above the aortic bow. The electrode was initially introduced with a straight guide reaching into the right atrium (RA). Afterwards, the straight guide was replaced by a conventional J guide and the electrode was pushed towards the anterolateral wall of the RA. The electrode tip was thus lying against the tricuspid valve. Subsequently, the guide was withdrawn 3 cm. The guide withdrawal, without moving the electrode, is associated with the passage of the electrode through the tricuspid valve. The electrode was advanced and finally the active fixation mechanism was deployed<xref ref-type="bibr" rid="B01">1</xref>.</p>

      <p>Um paciente do sexo masculino com 84 anos de idade apresentou piora da classe funcional da NYHA III/IV para IV/IV e palpita&#231;&#245;es, sem s&#237;ncope. O exame f&#237;sico revelou bradicardia, sem intercorr&#234;ncias adicionais. O eletrocardiograma mostrou bloqueio atrioventricular Mobitz II. Foi programado o implante de marca-passo permanente no paciente.</p>
      <p>O acesso &#224; veia subcl&#225;via foi realizado por pun&#231;&#227;o direta. O cateter guia foi inserido, entrou na veia subcl&#225;via e desceu em paralelo &#224; coluna vertebral, sem atravessar para o lado direito. Posteriormente, o cateter guia atravessou o seio coron&#225;rio e parou no &#225;trio direito. Foi diagnosticada veia cava superior esquerda persistente. Durante a fluoroscopia, outra caracter&#237;stica que auxilia no diagn&#243;stico &#233; a sombra paravertebral esquerda acima do arco a&#243;rtico. O eletrodo foi inicialmente introduzido com um cateter reto alcan&#231;ando o &#225;trio direito (AD). Em seguida, o cateter reto foi substitu&#237;do por um cateter J convencional e o eletrodo foi empurrado em dire&#231;&#227;o &#224; parede &#226;ntero-lateral do AD. A ponta do eletrodo ficou, dessa forma, posicionada contra a v&#225;lvula tric&#250;spide. Posteriormente o cateter foi recuado em 3 cm. A retirada do cateter, sem mover o eletrodo, est&#225; associada com a passagem do eletrodo atrav&#233;s da v&#225;lvula tric&#250;spide. O eletrodo foi avan&#231;ado e, finalmente, o mecanismo de fixa&#231;&#227;o ativa foi implantado<xref ref-type="bibr" rid="B01">1</xref>.</p>
