Incidence, Clinical Characteristics, and Impact of Absent Echocardiographic Signs in Patients with Infective Endocarditis after Transcatheter Aortic Valve Implantation

Abstract
Background
Echocardiography is the primary imaging modality for diagnosis of infective endocarditis (IE) in prosthetic valve endocarditis (PVE) including IE after transcatheter aortic valve implantation (TAVI). This study aimed to evaluate the characteristics and clinical outcomes of patients with absent compared with evident echocardiographic signs of TAVI-IE.
Methods
Patients with definite TAVI-IE derived from the Infectious Endocarditis after TAVI International Registry were investigated comparing those with absent and evident echocardiographic signs of IE defined as vegetation, abscess, pseudoaneurysm, intracardiac fistula or valvular perforation or aneurysm.
Results
Among 578 patients, 87 (15.1%) and 491 (84.9%) had absent (IE-neg) and evident (IE-pos) echocardiographic signs of IE, respectively. IE-neg were more often treated via a transfemoral access with a self-expanding device, and had higher rates for peri-interventional complications (e.g. stroke, major vascular complications) during the TAVI procedure (p < 0.05 for all). IE-neg had higher rates of IE caused by staphylococcus aureus (33.7% vs. 23.2%, p = 0.038) and enterococci (37.2% vs. 23.8%, p = 0.009), but lower rates of coagulase-negative staphylococci (4.7% vs. 20.0%, p = 0.001).IE-neg was associated with the same dismal prognosis for in-hospital mortality in a multivariate binary regression analysis (OR 1.51, 95%-CI 0.55-4.12) as well as a for 1-year mortality in a Cox regression analysis (HR 1.10, 95%-CI 0.67-1.80).
Conclusions
Even with negative echocardiographic imaging, patients who have undergone TAVI and presenting with positive blood cultures and symptoms of infection are a high-risk patient group having a reasonable suspicion of IE and the need for an early treatment initiation.
