      <title>Dados Cl&#237;nicos</title>
      <p>O rec&#233;m-nascido, em insufici&#234;ncia card&#237;aca com tronco arterial comum tipo I, foi corrigido com 15 dias de vida com 2.800 g de peso corporal pela t&#233;cnica de <italic>Barbero-Marcial</italic> . Na ocasi&#227;o fez-se a aproxima&#231;&#227;o direta da via de sa&#237;da do ventr&#237;culo direito (VD) com o tronco pulmonar e coloca&#231;&#227;o de uma monoc&#250;spide em posi&#231;&#227;o pulmonar.</p>
      <p>A evolu&#231;&#227;o foi adequada com o controle da insufici&#234;ncia card&#237;aca e se manteve sem sintomas e com desenvolvimento f&#237;sico normal. O exame cl&#237;nico descartava les&#245;es residuais como a insufici&#234;ncia valvar pulmonar. No decorrer do tempo, assintom&#225;tico, observou-se presen&#231;a de sopro sist&#243;lico na &#225;rea pulmonar, progressivo em intensidade ao lado de gradiente de press&#227;o crescente na regi&#227;o da monoc&#250;spide pulmonar. Com 2 anos ele era de 25 mmHg, com 5 anos de 34 mmHg, com 7 anos de 40, com 13 anos de 90 e com 16 anos de 149 mmHg. N&#227;o usa medicamentos espec&#237;ficos.</p>
      <p><bold>Exame f&#237;sico:</bold> bom estado geral, eupneico, acian&#243;tico, pulsos normais. Peso: 60 Kg, Alt.: 165 cm, PA: 110/70 mmHg, FC: 73 bpm. A aorta n&#227;o era palpada na f&#250;rcula.</p>
      <p>No prec&#243;rdio, <italic>ictus cordis</italic> n&#227;o palpado e sem impuls&#245;es sist&#243;licas na BEE. As bulhas card&#237;acas eram hiperfon&#233;ticas e auscultava-se sopro sist&#243;lico, +/++/4 de intensidade, rude, na &#225;rea pulmonar e ao longo da BEE. F&#237;gado n&#227;o palpado e pulm&#245;es limpos.</p>

      <title>Exames Complementares</title>
      <p><bold>Eletrocardiograma:</bold> Mostrava ritmo sinusal e sinais de bloqueio completo do ramo direito. AQRS= +160<sup>o</sup>, AP e AT= 50<sup>o</sup> C. A dura&#231;&#227;o do QRS era de 0,13&#8221;. N&#227;o havia potenciais de ventr&#237;culo esquerdo, com morfologia rR&#8217; em V1 e RS em V6.</p>
      <p><bold>Radiografia de t&#243;rax:</bold> Mostra &#225;rea card&#237;aca moderadamente aumentada &#224; custa dos arcos atrial e ventricular e trama vascular pulmonar normal. A cardiomegalia foi progressiva desde a corre&#231;&#227;o cir&#250;rgica, com &#237;ndice cardiotor&#225;cico atual de 0,60 ( <xref ref-type="fig" rid="f01">Figura 1</xref> ).</p>

      <p><bold>Ecocardiograma:</bold> Mostra o remendo interventricular bem posicionado e sem <italic>shunt</italic> residual. As cavidades direitas se mostram dilatadas em grau moderado e com disfun&#231;&#227;o ventricular. O VD est&#225; tamb&#233;m hipertrofiado. Gradiente m&#225;ximo entre VD e tronco pulmonar de 149 mmHg e m&#233;dio de 86 mmHg. As dimens&#245;es eram: Ao=32, AE= 28, VD= 34, VE= 41, septo= parede posterior= 7, fun&#231;&#227;o VE= 66%, APD= 22 e APE= 26 mm. Insufici&#234;ncia pulmonar discreta.</p>
      <p><bold>Tomografia do cora&#231;&#227;o:</bold> Mostrou os &#225;trios de dimens&#245;es normais, VD com hipertrofia m&#233;dio-apical e VDFVD= 135,2 ml/m<sup>2</sup> e disfun&#231;&#227;o de VD= 28%. A via de sa&#237;da do VD mostrava uma monoc&#250;spide calcificada e na planimetria da regi&#227;o a abertura valvar era de 0,95 cm<sup>2</sup>, com di&#226;metro de 14,3 x 6,2 cm. O septo interventricular estava &#237;ntegro e a aorta tinha calibre normal. Medidas de interesse: 1) Raiz de aorta: 35,4 x 35,0 mm (Z-score 3,3). 2) Aorta ascendente: 27,6 x 25,2 mm. 3) Arco a&#243;rtico proximal: 22,1 x 20,4 mm - m&#233;dio: 23,6 x 17,6 mm - distal: 21,0 x 17,6 mm. 4) Aorta descendente: - proximal: 13,9 x 13,5 mm - transi&#231;&#227;o t&#243;raco-abdominal: 11,4 x 9,6 mm. 5) Tronco pulmonar: 17,1 x 13,6 mm (Z-score -2,27). 6) Art&#233;ria pulmonar direita:16,3 x 13,0 mm (Z-score 0,35). 7) Art&#233;ria pulmonar esquerda: 11,7 x 10,1 mm (Z-score -0,96). 9) Ventr&#237;culo esquerdo: - Fra&#231;&#227;o de eje&#231;&#227;o: 49% - Volume diast&#243;lico final indexado: 82,4ml/m<sup>2</sup>.</p>
      <p><bold>Diagn&#243;stico cl&#237;nico:</bold> Tronco arterial comum tipo I operado precocemente sob a t&#233;cnica de <italic>Barbero-Marcial</italic> com estenose pulmonar acentuada e progressiva observada na juventude, em paciente assintom&#225;tico.</p>
      <p><bold>Racioc&#237;nio cl&#237;nico:</bold> Os elementos cl&#237;nicos evolutivos eram compat&#237;veis com diagn&#243;stico de estenose pulmonar que se instalou progressivamente desde a corre&#231;&#227;o do defeito de base, o tronco arterial comum. A aus&#234;ncia de sintomas era esperada em presen&#231;a da instala&#231;&#227;o insidiosa da obstru&#231;&#227;o atrav&#233;s do tempo. A progress&#227;o maior da estenose ocorreu nos &#250;ltimos tr&#234;s anos, provavelmente pela maior calcifica&#231;&#227;o da monoc&#250;spide nesse per&#237;odo.</p>
      <p><bold>Diagn&#243;stico diferencial:</bold> Les&#227;o da valva pulmonar ap&#243;s corre&#231;&#227;o cir&#250;rgica pode ocorrer em toda situa&#231;&#227;o na qual a valva pulmonar seja anteriormente reparada. Seu diagn&#243;stico &#233; simples atrav&#233;s da presen&#231;a de sopro sist&#243;lico na &#225;rea pulmonar, acrescentado da hipertrofia mioc&#225;rdica de VD nos exames de imagem.</p>
      <p><bold>Conduta:</bold> Em face da progress&#227;o do defeito residual a n&#237;vel da valva pulmonar, j&#225; com caracteres adquiridos como hipertrofia mioc&#225;rdica e disfun&#231;&#227;o de VD, a conduta de interven&#231;&#227;o na regi&#227;o obstru&#237;da foi facilmente assimilada. Dada a anatomia adequada da regi&#227;o da valva pulmonar com di&#226;metro de 14 mm e sem dilata&#231;&#227;o da via de sa&#237;da do VD, imaginou-se pertinente a abordagem da mesma por cateterismo card&#237;aco intervencionista. A coloca&#231;&#227;o de pr&#243;tese valvar tipo <italic>Melody</italic> foi a t&#233;cnica de escolha, com o inconveniente da possibilidade de ocorr&#234;ncia de endocardite infecciosa em uma valva de origem de veia jugular bovina. As art&#233;rias coron&#225;rias bem afastadas da via de sa&#237;da do VD favoreceram a suposi&#231;&#227;o tra&#231;ada.</p>
      <p><bold>Coment&#225;rios:</bold> A t&#233;cnica de <italic>Barbero-Marcial</italic> <sup><xref ref-type="bibr" rid="B1">1</xref></sup> para corre&#231;&#227;o do tronco arterial comum, desenvolvida nos idos de 1989, &#233; habitualmente acompanhada de insufici&#234;ncia valvar pulmonar em face da dilata&#231;&#227;o da via de sa&#237;da do VD na anastomose com o tronco pulmonar, tracionado em dire&#231;&#227;o &#224; mesma. Acompanha ainda a coloca&#231;&#227;o de uma monoc&#250;spide, que analogamente ao que ocorre ap&#243;s a corre&#231;&#227;o da tetralogia de <italic>Fallot</italic> , favorece tamb&#233;m &#224; evolu&#231;&#227;o posterior de regurgita&#231;&#227;o pulmonar progressiva. Esses pacientes necessitam de corre&#231;&#227;o do defeito residual e quase sempre por interven&#231;&#227;o cir&#250;rgica, em face da grande dilata&#231;&#227;o da regi&#227;o, que impossibilita a coloca&#231;&#227;o de pr&#243;tese endovenosa.</p>
      <p>A preserva&#231;&#227;o da via de sa&#237;da mais estreita, como observada no caso apresentado, traz &#224; baila a imagina&#231;&#227;o e discuss&#227;o de como deveria se suceder em pacientes semelhantes operados, como mais comumente na tetralogia de <italic>Fallot</italic> . Tal fato poderia ocorrer mais vezes, desde que o cirurgi&#227;o preservasse mais a via de sa&#237;da do VD em uma &#225;rea mais estreita, a permitir que evolutivamente a estenose pulmonar predominasse sobre a insufici&#234;ncia valvar. Essa prefer&#234;ncia decorre do fato de que a les&#227;o mioc&#225;rdica de sobrecarga de volume seja mais delet&#233;ria do que a estenose pulmonar, esta provocada mais pela calcifica&#231;&#227;o da monoc&#250;spide.</p>
      <p>O ideal &#233; que esses pacientes sejam sempre devidamente monitorados, a fim de se preservar a condi&#231;&#227;o preconizada para evolu&#231;&#227;o mais favor&#225;vel a mais longo prazo.</p>

        <title>Clinical Data</title>
        <p>The newborn, in heart failure with <italic>truncus arteriosus</italic> type I, underwent repair at 15 days of age, weighing 2800 g. of body weight, by the Barbero-Marcial technique. At that time, the right ventricular outflow tract was approached directly with the pulmonary trunk and a monocusp valve was placed in the pulmonary position.</p>
        <p>The evolution was adequate, with heart failure control, and he remained asymptomatic and showed normal physical development. The clinical examination ruled out residual lesions, such as pulmonary valve insufficiency. Over time, while asymptomatic, a systolic murmur was identified in the pulmonary area, of progressive intensity, together with an increasing pressure gradient in the region of the pulmonary monocusp. At 2 years of age, it was 25 mmHg; at 5 years, 34 mm Hg; at 7 years, it was 40; at 13 years it was 90 and at 16 years it was 149 mmHg. The patient did not use any specific medications.</p>
        <p><bold>Physical Examination:</bold> good overall status, eupneic, acyanotic, normal pulses. Weight: 60 Kgs, Height: 165 cm, BP: 110/70 mm Hg, HR: 73 bpm. The aorta was nonpalpable at the suprasternal notch. In the precordium, the apical impulse was nonpalpable and there were no systolic impulses in the left sternal border (LSB). The heart sounds were hyperphonetic and a +/++/4 rough systolic murmur was auscultated in the pulmonary area and along the LSB. Nonpalpable liver and clear lungs.</p>

        <p><bold>Electrocardiogram</bold> showed sinus rhythm and signs of complete right bundle-branch block. AQRS = +160<sup>o</sup>, AP and AT = 50<sup>o</sup>C. The QRS duration was 0.13&#8221;. There were no left ventricular potentials, with rR&#8217; morphology in V1 and RS in V6.</p>
        <p><bold>Chest x-ray</bold> showed moderately increased cardiac area on account of the atrial and ventricular arches and normal pulmonary vascular network. Cardiomegaly was progressive since the surgical correction, with a current cardiothoracic index of 0.60 ( <xref rid="f01001" ref-type="fig">figure 1</xref> ).</p>

        <p><bold>Echocardiogram</bold> showed a well-positioned interventricular patch and no residual shunt. The right cavities were moderately dilated and showed ventricular dysfunction. The RV also showed hypertrophy. The maximum gradient between the RV and the pulmonary trunk was 149 mmHg, with an average of 86 mmHg. The dimensions were: Ao = 32, LA = 28, RV = 34, LV = 41, septum = posterior wall = 7, LV function = 66%, RPA = 22 and LPA = 26 mm. Mild pulmonary insufficiency.</p>
        <p><bold>Cardiac tomography</bold> showed normal-sized atria, right ventricle with medio-apical hypertrophy and RVEDV = 135.2 mL/ m<sup>2</sup>and RV dysfunction = 28%. The RV outflow tract showed a calcified monocusp and the planimetry of the region showed the valve opening was 0.95 cm<sup>2</sup>, with a diameter of 14.3 x 6.2 cm. The interventricular septum was intact, and the aorta had a normal caliber. Measures of interest: 1) Aortic root: 35.4 x 35.0mm (Z-score 3.3). 2) Ascending aorta: 27.6 x 25.2mm. 3) Proximal aortic arch: 22.1 x 20.4mm - mean: 23.6 x 17.6mm - distal: 21.0 x 17.6mm 4) Descending aorta: - proximal: 13.9 x 13.5mm - thoraco-abdominal transition: 11.4 x 9.6mm. 5) Pulmonary trunk: 17.1 x 13.6 mm (Z-score -2.27). 6) Right pulmonary artery: 16.3 x 13.0 mm (Z-score 0.35). 7) Left pulmonary artery: 11.7 x 10.1 mm (Z-score -0.96). 9) Left ventricle: - Ejection fraction: 49% - Indexed end-diastolic volume: 82.4 mL / m<sup>2</sup>.</p>
        <p><bold>Clinical Diagnosis:</bold><italic>Truncus arteriosus</italic> Type I submitted to an early operation using the Barbero-Marcial technique, with severe and progressive pulmonary stenosis observed in adolescence, in an asymptomatic patient.</p>
        <p><bold>Clinical reasoning:</bold> The evolution clinical elements were compatible with the diagnosis of progressive pulmonary stenosis since the correction of the basal defect, the <italic>Truncus arteriosus</italic> Type I. The absence of symptoms was expected in the presence of the insidious occurrence of the obstruction over time. The greatest progression of stenosis had occurred in the last three years, probably due to the greater calcification of the monocusp during this period.</p>
        <p><bold>Differential diagnosis:</bold> Pulmonary valve injury after surgical correction can occur in any situation in which the pulmonary valve is previously repaired. Its diagnosis is simple, attained through the presence of a systolic murmur in the pulmonary area, plus right ventricular myocardial hypertrophy in imaging exams.</p>
        <p><bold>Conduct:</bold> Considering the progression of the residual defect at the pulmonary valve level, with acquired characteristics such as myocardial hypertrophy and right ventricular dysfunction, the intervention approach in the obstructed region was easily assimilated. Given the adequate anatomy of the pulmonary valve region, with a diameter of 14 mm and without RV outflow tract dilation, it was considered pertinent to approach it using interventional cardiac catheterization. The use of a Melody prosthetic valve was the technique of choice, with the inconvenience of the possibility of occurrence of infectious endocarditis in a bovine jugular vein valve. The fact that the coronary arteries were well away from the right ventricular outflow tract favored the established assumption.</p>
        <p><bold>Comments:</bold> The use of the Barbero-Marcial<sup><xref rid="B1" ref-type="bibr">1</xref></sup>technique for correction of the <italic>truncus arteriosus</italic> Type I, developed in 1989, is usually accompanied by pulmonary valve insufficiency due to the RV outflow tract dilation at the anastomosis with the pulmonary trunk, which is pulled towards it. It also accompanies the placement of a monocusp, which, analogously to what occurs after the correction of the Tetralogy of Fallot, also favors the subsequent evolution of progressive pulmonary regurgitation. These patients require correction of the residual defect and almost always by surgical intervention, due to the large dilation in the region, which makes it impossible to place an intravenous prosthesis.</p>
        <p>The preservation of the narrower outflow tract, as observed in the case presented herein, brings to mind the occurrence and discussion of how it should happen in similar operated patients, as most commonly in the Tetralogy of Fallot. This fact could occur more frequently, as long as the surgeon better preserved the RV outflow tract in a narrower area, allowing the pulmonary stenosis evolution to predominate over valve regurgitation. This preference stems from the fact that the volume overload myocardial lesion is more harmful than pulmonary stenosis, which is caused more often by monocusp calcification.</p>
        <p>Ideally, these patients should always be adequately monitored, aiming to preserve the recommended condition for a more favorable evolution in the longer term.</p>
