    <p><bold>Clinical data:</bold> Heart murmur was identified at auscultation in childhood, but the diagnosis of aortic coarctation associated with atrial septal defect was attained when the patient was 15 years old. The patient practiced regular physical activity and did not report symptoms for up to 5 years, when he became sedentary. He received specific anti-hypertensive medication.</p>
    <p><bold>Physical examination:</bold> patient was eupneic, acyanotic, obese, ample pulses in the upper limbs and decreased in the lower limbs. Weight: 113 kg; height: 177 cm; Body Mass Index (BMI): 36.1 kg/m<sup>2</sup>; RUL BP was the same in the LUL, 149/89 mmHg; right inferior limb BP = 113/77 mmHg; Heart rate (HR): 82 bpm; oxygen saturation of 95%. The aorta was clearly palpable at the suprasternal notch.</p>
    <p>The apex beat was not palpable in the precordium and there were no systolic impulses in the left sternal border (LSB). Normal heart sounds; constant split second sound and rough systolic murmur + / ++ / 4, was heard in the upper LSB. The liver was not palpable.</p>
    <sec>
      <title>Complementary Examinations</title>
      <p><bold>The Electrocardiogram</bold> showed sinus rhythm, first-degree atrioventricular block and complete right bundle-branch block. A P: +50&#186;, AQRS: +115&#186;, AT: 0&#186;. QRS Duration: 0.14", PR 0.21 ms (<xref ref-type="fig" rid="f1">Figure 1</xref>).</p>

      <p><bold>Chest x-ray</bold> showed a slightly enlarged cardiac area (cardiothoracic index of 0.61) at the expense of the right ventricular border. Pulmonary vasculature was increased and the medial border was rectified. There was no aortic dilatation, but hyperrefringency on the lower edges of the ribs was observed (<xref ref-type="fig" rid="f1">Figure 1</xref>).</p>
      <p><bold>The echocardiogram</bold> showed marked right heart chamber dilation (right ventricle - RV 52 mm), a slight increase of the left atrium (45 mm), systolic blood pressure of 44 mmHg in the RV. The ascending aorta was normal (37 mm) and showed no myocardial hypertrophy (septum/posterior wall of 11 mm). Left ventricular function (75%) and size (39 mm) were normal. TEE showed major discontinuity of the atrial septum at two points, of 8 and 26 mm each, with edges present in the entire contour. No abnormalities were identified in the aorta.</p>
      <p><bold>CT angiography of the aorta</bold>, performed after clinical suspicion of aortic coarctation, confirmed the diagnosis, immediately distal to the left subclavian artery, with paravertebral, mediastinal and intercostal artery collaterals, which caused opacification of the descending aorta, with 16 mm in diameter. The internal thoracic arteries and the supra-aortic trunks were enlarged. Marked right chambers and pulmonary trunk enlargement was also observed (<xref ref-type="fig" rid="f2">Figure 2</xref>).</p>

      <p><bold>Clinical diagnosis:</bold> large atrial septal defect and marked aortic coarctation at the isthmus region, adjacent to the left subclavian artery, without ascending aortic dilatation, with no myocardial hypertrophy and with exuberant collateral circulation.</p>
      <p><bold>Clinical reasoning:</bold> the clinical elements of aortic coarctation and ASD are easily identifiable, represented by contrast of pulses and blood pressure between limbs in the first abnormality, and in the second, high murmur at the LSB, right bundle-branch block and increased pulmonary vasculature. It is evident that, even in heart disease with long-term pressure overload, there is no myocardial hypertrophy, or signs of electrical overload and with few symptoms. These aspects originate from the evolutionary development of efficient collateral circulation.</p>
      <p><bold>Differential Diagnosis:</bold> the association of the two defects is unusual, making clinical reasoning difficult, even though the abovementioned elements are indicative of the defects. Aortic obstruction in an adult patient, in general, also result from prior aortitis, as seen in Takayasu's disease, Kawasaki, in connective tissue diseases and infectious diseases such as syphilis.</p>
      <p><bold>Conduct:</bold> Considering the long-standing systolic effects of arterial hypertension, even without myocardial hypertrophy, surgical indication is mandatory, aimed at relieving arterial obstruction, which leads to the onset of myocardial fibrosis, heart failure, arrhythmias and early death. It was decided to perform dilation of the isthmus region through interventional catheterization from the right femoral artery using a 40 x 15 mm stent, encompassing the left subclavian artery origin. The pressures before the procedure, were 30/12 in the RV; in the PT, 30/15-20; ascending aorta, 140/ 80-100; descending aorta, 90/60-70. There was immediate BP normalization and equalization in the ascending and descending aorta (128/88-101 mmHg) after adequate dilation of the region (<xref ref-type="fig" rid="f2">Figure 2</xref>). The patient reported easier breathing and well-being. The systolic murmur of the relative pulmonary stenosis decreased in intensity after the subsequent ASD closure using a 36 CERA(tm) device.</p>
      <p><bold>Comments:</bold> aortic coarctation can manifest later in life, in adulthood, in view of the collateral circulation development that supplies the descending aorta, therefore lowering blood pressure in the upper limbs and preventing progression to myocardial hypertrophy. Similarly, the atrial septal defect, being an abnormality with right cavity volume overload, becomes so tolerable that the discovery of the disorder in adulthood becomes even incidental, even after uncomplicated pregnancies.</p>
      <p>The association of these defects is unusual and develops independently without significant interference from each other. The percutaneous therapeutic approach has become a reality to the point that, in this patient, it was enthusiastically performed in spite of the blind-end aortic coarctation contiguous to the left subclavian artery. The simultaneity of the percutaneous procedures has been scarcely reported in the literature.<xref ref-type="bibr" rid="B1">1</xref> This case exemplifies a successful simultaneous percutaneous procedure.</p>

        <p><bold>Diagn&#243;stico cl&#237;nico:</bold> comunica&#231;&#227;o interatrial grande e coarta&#231;&#227;o da aorta acentuada na regi&#227;o &#237;stmica, cont&#237;gua &#224; art&#233;ria subcl&#225;via esquerda, sem dilata&#231;&#227;o da aorta ascendente, sem hipertrofia mioc&#225;rdica e com circula&#231;&#227;o colateral exuberante.</p>
        <p><bold>Racioc&#237;nio cl&#237;nico:</bold> os elementos cl&#237;nicos da coarta&#231;&#227;o da aorta e da comunica&#231;&#227;o interatrial s&#227;o de f&#225;cil identifica&#231;&#227;o, representados pelo contraste de pulsos e da press&#227;o arterial entre os membros na primeira anomalia, e, na segunda, sopro alto na BEE, bloqueio do ramo direito e trama vascular pulmonar aumentada. &#201; not&#243;rio que, mesmo em cardiopatia com sobrecarga de press&#227;o de longa data, n&#227;o haja hipertrofia mioc&#225;rdica, nem sinais de sobrecarga el&#233;trica e com poucos sintomas. Esses aspectos decorrem do desenvolvimento evolutivo de circula&#231;&#227;o colateral eficiente.</p>
        <p><bold>Diagn&#243;stico diferencial:</bold> a associa&#231;&#227;o dos dois defeitos &#233; incomum, o que dificulta o racioc&#237;nio cl&#237;nico, apesar de os elementos citados serem demonstrativos dos mesmos. Obstru&#231;&#245;es da aorta no adulto, em geral, decorrem tamb&#233;m de aortite pr&#233;via, como se sucede na doen&#231;a de Takayasu, Kawasaki, em doen&#231;as do tecido conjuntivo e em doen&#231;as infecciosas, como a s&#237;filis.</p>
        <p><bold>Conduta:</bold> Em face da repercuss&#227;o sist&#243;lica de longa data com hipertens&#227;o arterial, mesmo sem hipertrofia mioc&#225;rdica, torna-se imperiosa a indica&#231;&#227;o operat&#243;ria visando ao al&#237;vio da obstru&#231;&#227;o arterial, que suscita aparecimento de fibrose mioc&#225;rdica, insufici&#234;ncia card&#237;aca, arritmias e morte mais precocemente. Preferiu-se a dilata&#231;&#227;o da regi&#227;o &#237;stmica pelo cateterismo intervencionista a partir da art&#233;ria femoral direita com stent 40 x 15 mm, englobando a emerg&#234;ncia da art&#233;ria subcl&#225;via esquerda. As press&#245;es, antes do procedimento, eram em VD de 30/12; TP de 30/15-20; AoAsc de 140/80-100, AoDesc de 90/60-70. Houve imediata normaliza&#231;&#227;o e equaliza&#231;&#227;o da press&#227;o arterial na aorta ascendente e descendente (128/88-101 mmHg), ap&#243;s a amplia&#231;&#227;o adequada da regi&#227;o (<xref ref-type="fig" rid="f4">Figura 2</xref>). O paciente referiu respira&#231;&#227;o mais f&#225;cil, al&#233;m de bem-estar. O sopro sist&#243;lico da estenose pulmonar relativa diminuiu de intensidade, ap&#243;s o fechamento subsequente da comunica&#231;&#227;o interatrial, com pr&#243;tese Cera 36.</p>
        <p><bold>Coment&#225;rios:</bold> a coarta&#231;&#227;o da aorta pode se exteriorizar tardiamente na vida, na idade adulta, em vista do desenvolvimento de circula&#231;&#227;o colateral que nutre a aorta descendente, diminuindo da&#237; a hipertens&#227;o arterial em membros superiores e impedindo a evolu&#231;&#227;o para hipertrofia mioc&#225;rdica. Da mesma maneira, a comunica&#231;&#227;o interatrial, por ser anomalia com sobrecarga de volume das cavidades direitas, torna-se t&#227;o toler&#225;vel que a descoberta na idade adulta passa a ser at&#233; fortuita, mesmo ap&#243;s gesta&#231;&#245;es sem complica&#231;&#245;es. A associa&#231;&#227;o desses defeitos &#233; incomum e ambos evolu&#237;am de maneira independente, sem expressiva interfer&#234;ncia de um no outro. A conduta terap&#234;utica percut&#226;nea se tornou uma realidade a ponto de, neste paciente, ter havido entusiasmo em realiz&#225;-lo mesmo em coarta&#231;&#227;o da aorta cont&#237;gua &#224; art&#233;ria subcl&#225;via esquerda e com fundo cego. A simultaneidade do procedimento percut&#226;neo tem sido pouco comentada na literatura.<xref ref-type="bibr" rid="B1">1</xref> Este caso se torna exemplo de uma atua&#231;&#227;o percut&#226;nea simult&#226;nea de sucesso.</p>
