PVE carried significant perioperative risks, and was an independent risk factor of overall mortality.

Appropriate postoperative antibiotic treatment in patients with infective endocarditis (IE) reduces the risks of recurrence and mortality. However, concerns about adverse drug reactions arise due to prolonged antibiotic usage. Therefore, we compared the recurrence and mortality rates according to the duration of postoperative antibiotic therapy in patients with IE. From 2005 to 2017, we retrospectively reviewed 416 patients with IE treated at a tertiary hospital in South Korea; among these, 216

Mini-access open arch repair is technically feasible and achieved excellent early outcomes.

Patients with diabetes mellitus (DM) are at a higher risk of infectious diseases, and exercise is an important treatment modality for DM. Despite their susceptibility to infection in diabetic patients, the association between the amount of physical activity and the incidence of infective endocarditis (IE) is unclear. We attempted to demonstrate risk reduction by physical activity in diabetic patients with IE. From the National Health Insurance database, patients with DM were verified, and the in

In this propensity-matched cohort of patients who underwent AVR for severe AS, we did not detect significant differences in the rates of the primary composite of death, stroke, or rehospitalization at 12 months when comparing RD-AVR with SAVR and TAVR. Because the study was underpowered, the results should be considered as hypothesis generating highlighting the need for further research.

Since the introduction of transcatheter aortic valve (AV) implantation as a viable option, surgical bioprosthetic AVs have recently started incorporating shorter struts considering future valve-in-valve procedures. However, the effect of leaflet coaptation geometry on the longevity of these valves remains unexplored. To address this gap, we performed a finite element analysis on bioprosthetic AVs with varying strut heights using a two-way fluid-structure interaction method. To establish a baseli

Congenital atresia of the left main coronary artery (LMCA) is an extremely rare coronary anomaly that necessitates surgical correction. Patients with LMCA atresia may have various clinical symptoms, which are determined by the degree of collateral vessel development from the right coronary system, the metabolic demands of the heart, and concomitant mitral insufficiency caused by myocardial ischemia. Unlike in adults, there are limited surgical options for coronary artery disease in children. Her

A 3-dimensional printing model may be an important guiding tool for establishing surgical planning in complex cardiac tumors. See Commentaries on pages 41 and 43. The primary cardiac tumor is extremely rare, constituting 0.3% to 0.7% of all cardiac tumors.1Castello J. Silvay G. Characterization and management of cardiac t

BACKGROUNDS: The association between weight change in patients with diabetes, and the development of infective endocarditis (IE) has never been studied. Therefore, we evaluated the associations of weight changes in patients with diabetes with the development of IE. METHODS: In this Korean population-based cohort study, we included patients with diabetes aged ≥20 years who underwent health screenings twice in a 2-year interval between 2009 and 2012. Patients were categorized into five groups acco

Diabetic patients may require rigorous blood pressure control and simultaneous avoidance of excessive weight loss to prevent IE.

As mediastinal sarcomas commonly present as large tumors invading adjacent vital structures, complete resection is frequently challenging. For such tumors, aggressive surgical strategies, such as the resection and reconstruction of the invaded vital structures under cardiopulmonary bypass, may be required to achieve complete resection and to improve survival. Herein, we report a case of recurrent mediastinal sarcoma invading the aortic arch and arch vessels that was successfully removed by total
