Key result
Emergency TAVR using only echocardiography measurements successfully treated a patient with decompensated severe aortic stenosis and cardiorenal syndrome, improving dyspnea and renal function.

Emergent TAVR guided solely by echocardiography is a feasible and effective rescue strategy for patients with decompensated severe aortic stenosis and cardiorenal syndrome who cannot undergo CT imaging.
May support echo-only emergency TAVR when CT unavailable; hypothesis-generating and requires prospective validation before broader use.
BACKGROUND: Severe aortic stenosis (AS) may lead to acute decompensated heart failure resistant to medical treatment. Here, we report a successful emergent transcatheter aortic valve replacement (TAVR) in a patient presenting with decompensated severe AS accompanied by cardiorenal syndrome. CASE PRESENTATION: A 82-year-old man presented at our emergency department with aggravated dyspnea. His chest X-ray showed bilateral pulmonary edema, and laboratory examination revealed acute kidney injury. Transthoracic echocardiography (TTE) revealed low-flow, low-gradient AS with decreased left ventricular systolic function. With a diagnosis of acute decompensated heart failure combined with cardiorenal syndrome, we opted to perform emergent TAVR. Ultimately, we successfully performed emergent TAVR using only TTE and 3-D transesophageal echocardiography (TEE) measurements. CONCLUSIONS: This report presents a case of decompensated severe AS accompanied by cardiorenal syndrome that was treated successfully with emergent TAVR. Thus, emergent TAVR using only echocardiography measurements is a feasible and safe option for treating decompensated heart failure accompanied by cardiorenal syndrome the clinical setting.
