P30 A STONE ON THE HEART

Abstract

Abstract We report a case of a 71–year–old female patient presented to our observation with worsening episodes of chest pain associated with cold sweat and spontaneous regression. Seven months earlier, the patient had undergone mitral valve replacement surgery with bioprosthesis for severe insufficiency. Pre–operative coronary angiography had documented the absence of significant lesions of the coronary arteries. Four months after the operation, hospitalisation was necessary due to an infective endocarditis on the prosthetic valve, effectively treated with specific antibiotic therapy. The patient came to the Emergency Department reporting episodes of stress related angina, lasting for a few days. The ECG documented sinus rhythm and non–specific anomalies of the ventricular repolarization phase. The haematochemical tests showed a minimal increase in the HS troponine values. Ultrasound documented normal left ventricular dimensions, no regional kinetic abnormalities with normal global systolic function and good functioning of the mitral bioprosthesis. The patient was admitted in our department of cardiology for further investigations. The next day the patient complained of severe oppressive chest pain with ECG evidence of diffuse ST–T segment depression and elevation in aVR and V1. Blood pressure was 170/90 mmHg and ultrasound showed apex hypokinesia with severely reduced systolic function. Nitrate s.l was administered with gradual improvement of symptoms and normalisation of the ECG. The patient underwent coronary angiography but during the first injection of contrast test, an anomalous stagnation of the contrast was highlighted in the aorta. It was urgently decided to perform aortic CT scan. The examination showed the presence of a voluminous pseudoaneurysm starting from the aortic bulb, partially thrombosed, which compressed the left main and the origin of the circumflex artery. The patient was therefore subjected to cardiac surgery the following day, with a good follow–up result one month after discharge.
