Résumé
An 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-ST-elevation myocardial infarction. Echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. The patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pulmonary edema. The day after, he was submitted to coronary angiography showing bivessel coronary disease. Given the high estimated operative risk, the patient was treated with angioplasty and bare metal stent implantation on both right coronary and circumflex artery; contemporarily, balloon aortic valvuloplasty [BAV] was performed with anterograde technique, obtaining a significant increase in planimetric valve area and reduction in transvalvular peak gradient. Few days after the procedure echocardiogram showed an increase in left ventricular ejection fraction, moderate aortic stenosis with mild regurgitation and moderate mitral regurgitation. Hemodynamic and clinical stabilization were also obtained, allowing amine support discontinuation and weaning from mechanical ventilation. At three months follow-up, the patient reported a further clinical improvement from discharge, and echocardiographic evaluation showed moderate aortic stenosis and an additional increase in left ventricular function and decrease in mitral regurgitation degree. In conclusion, combined BAV and coronary angioplasty were associated in our patient with hemodynamic and clinical stabilization as well as with a significant reduction in transvalvular aortic gradient and mitral regurgitation and an increase in left ventricular ejection fraction both in-hospital and at three month followup; this case suggests that these procedures are feasible even in hemodynamically unstable patients and are associated with a significant improvement in quality of life.
