Puede generar cuadros cl\u00ednicos severos como shock cardiog\u00e9nico y muerte, por lo que se necesita un tratamiento precoz. A pesar de que este suele ser exitoso, los pacientes pueden desarrollar complicaciones el\u00e9ctricas y mec\u00e1nicas graves a largo plazo. Por esta raz\u00f3n, es crucial el seguimiento cl\u00ednico y electrofisiol\u00f3gico continuo y riguroso.<br \/>Caso cl\u00ednico: Paciente masculino de 19 a\u00f1os, con antecedente de estenosis a\u00f3rtica cr\u00edtica neonatal asociado a v\u00e1lvula a\u00f3rtica bic\u00faspide y coartaci\u00f3n de aorta, corregidas quir\u00fargicamente en el primer a\u00f1o de vida, con controles peri\u00f3dicos posteriores.

It can lead to severe clinical presentations such as cardiogenic shock and death, thus requiring early treatment. Although treatment is often successful, patients can develop serious long-term electrical and mechanical complications. For this reason, continuous and rigorous clinical and electrophysiological monitoring is crucial.<br \/>Clinical Case: A 19-year-old male patient with a history of critical neonatal aortic stenosis associated with bicuspid aortic valve and coarctation, surgically corrected in the first year of life, with subsequent periodic follow-up. At age 15, he experienced cardiorespiratory arrest during physical activity, with successful recovery of spontaneous circulation. In this context, severe aortic stenosis was diagnosed, and aortic plastic surgery was performed with good initial progress. During outpatient follow-up, he developed severe, clinically silent atrioventricular conduction abnormalities, which led to the implantation of a permanent pacemaker.<br \/>Conclusion: This case underscores the need for rigorous clinical and electrophysiological monitoring in patients with complex congenital heart disease, even in the absence of symptoms.<\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=\u00bb4.27.5&#8243; text_font=\u00bb||||||||\u00bb text_font_size=\u00bb15px\u00bb text_line_height=\u00bb2em\u00bb header_font=\u00bb||||||||\u00bb header_2_font=\u00bb||||||||\u00bb header_3_font=\u00bbEB Garamond||||||||\u00bb header_3_font_size=\u00bb24px\u00bb header_3_line_height=\u00bb1.4em\u00bb header_4_font=\u00bb|700||on|||||\u00bb header_4_text_color=\u00bb#ffdaa4&#8243; header_4_font_size=\u00bb12px\u00bb header_4_letter_spacing=\u00bb2px\u00bb header_4_line_height=\u00bb2em\u00bb min_height=\u00bb72.6px\u00bb text_line_height_tablet=\u00bb\u00bb text_line_height_phone=\u00bb1.6em\u00bb text_line_height_last_edited=\u00bbon|phone\u00bb locked=\u00bboff\u00bb global_colors_info=\u00bb{}\u00bb]<\/p>\n<h3>Keywords<\/h3>\n<p>Aortic stenosis, cardiopulmonary arrest, severe atrioventricular conduction disorders, pacemaker.<\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=\u00bb4.27.5&#8243; text_font=\u00bb||||||||\u00bb text_font_size=\u00bb15px\u00bb text_line_height=\u00bb2em\u00bb header_font=\u00bb||||||||\u00bb header_2_font=\u00bb||||||||\u00bb header_3_font=\u00bbEB Garamond||||||||\u00bb header_3_font_size=\u00bb24px\u00bb header_3_line_height=\u00bb1.4em\u00bb header_4_font=\u00bb|700||on|||||\u00bb header_4_text_color=\u00bb#ffdaa4&#8243; header_4_font_size=\u00bb12px\u00bb header_4_letter_spacing=\u00bb2px\u00bb header_4_line_height=\u00bb2em\u00bb text_line_height_tablet=\u00bb\u00bb text_line_height_phone=\u00bb1.6em\u00bb text_line_height_last_edited=\u00bbon|phone\u00bb locked=\u00bboff\u00bb global_colors_info=\u00bb{}\u00bb]<\/p>\n<h3>Introducci\u00f3n<\/h3>\n<p>La estenosis a\u00f3rtica cr\u00edtica neonatal (EAo) es una malformaci\u00f3n cong\u00e9nita, de car\u00e1cter progresivo, que produce obstrucci\u00f3n al flujo de salida del ventr\u00edculo izquierdo, generando as\u00ed aumento en las presiones de llenado del mismo, lo que posibilita desencadenar en poco tiempo cuadros cl\u00ednicos severos como insuficiencia cardiaca congestiva, shock cardiog\u00e9nico, falla multiorg\u00e1nica y muerte. La EAo representa entre el 3-6\u202f % de las cardiopat\u00edas cong\u00e9nitas y suele, por lo general, asociarse a v\u00e1lvula a\u00f3rtica bic\u00faspide (VAB) y coartaci\u00f3n de aorta (CoAo).
