Hallazgos ergoespirométricos en un paciente con fístula coronaria / Cardiopulmonary exercise test findings in a patient with a coronary fistula

RESUMEN

Resumen En la práctica médica es común encontrar retos en el diagnóstico de los pacientes. Este es un caso que realiza un cuadro clínico de una mujer con síntomas de dolor torácico y disnea de esfuerzo con diagnóstico final de una rara presentación de fístula coronaria, a quien se le realizaron múltiples estudios cardiovasculares descritos, como métodos no invasivos para el hallazgo de dicha alteración, sin llegar a un diagnóstico, para, finalmente, realizar el procedimiento estándar de oro, como lo es la arteriografía coronaria, por los resultados anormales de la ergoespirometría indicada por disnea de etiología no clara.

ABSTRACT

Abstract In medical practice, it is common to encounter challenges in the diagnosis of patients. The case report gives a detailed description of the clinical history of a young adult female patient who presented the cardinal warning signs of chest pain and longstanding dyspnea on exertion and was ultimately diagnosed with a rare presentation of a coronary fistula. The patient had previously undergone multiple cardiovascular tests described in the medical literature as a non-invasive means for identifying this disorder (conventional stress test, transthoracic echocardiogram, and myocardial perfusion), but with no definitive diagnosis. Finally, she underwent coronary arteriography, the gold standard procedure, due to her abnormal results on the cardiopulmonary exercise test (CPET), which was ordered due to dyspnea of unclear etiology.
