We assessed the incidence of aortic valve surgery intervention in the treatment of infective endocarditis (IE) after transcatheter aortic valve replacement (TAVR) and compared the characteristics and outcomes of surgical intervention versus medical management alone in this cohort using a nationwide data set. We identified all the hospitalizations in patients undergoing TAVR who developed IE within 1-year (i.e., early IE) of the procedure from 2014 to 2017 using the Nationwide Readmission Database (NRD). The primary outcomes of the study were in-hospital mortality. A total of 906 hospitalizations were identified for IE amongst the TAVR patients from 2014 to 2017 of which 20 (2.21%) underwent aortic valve surgery during the hospitalization. Patients undergoing surgery were younger, more likely to have Staphylococcus aureus endocarditis, cardiogenic shock, and acute kidney injury (AKI) during the hospitalization. There were no significant differences in in-hospital mortality (9.9% vs. 12.4%, p = 0.824; adjusted odds ratio (aOR): 0.26 (0.01-1.58), p = 0.223) and 30-day readmissions. However, the length of stay and hospitalization costs were higher in surgical intervention group. The important predictors of in-hospital mortality in TAVR-related IE patients were dialysis during IE hospitalization, AKI, cardiogenic shock, Staphylococcus aureus endocarditis, stroke, and female sex. The utilization of surgical management for IE post-TAVR during the index hospitalization is low, and there is no significant mortality benefit with surgical intervention as compared with the medical management.

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Mitral Regurgitation III: Medical Management

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
