This meta-analysis indicates that TVr is more beneficial compared with TVR in terms of all-cause mortality. From the available data, TVr is not associated with an increased risk of tricuspid reoperation compared with TVR.

In patients with moderate AS and LVSD, AVR reduces the risk of all-cause death. A prospective randomized trial is warranted to confirm our findings.

BACKGROUND: This study was conducted to evaluate the occurrence rate and risk factors of subaortic pannus (SAP) after bileaflet mechanical aortic valve (AV) replacement. METHODS: Between 1990 and 2014, 862 patients underwent primary AV replacement with bileaflet mechanical prosthesis. SAP was defined as (1) gradual increase in mean pressure gradient through mechanical AV without any evidence of motion limitation of the leaflets on echocardiography and (2) AV mean pressure gradient >40 mm Hg or A

BACKGROUND: Non-vitamin K direct oral anticoagulant (DOAC) is effective for prevention of embolic events in nonvalvular atrial fibrillation (AF) patients. However, the effectiveness and safety of DOAC in AF patients who have bioprosthetic heart valve (BPHV) is largely unknown. METHODS: We retrospectively identified patients with AF and BPHV, using the diagnostic code and medical device and surgery information from the Korean National Health Insurance Service database, between 2013 and 2018. A 1:

The recent data from the KHVSR showed increasing trends for complex procedures and minimally invasive surgery in heart valve surgery in Korea, and demonstrated remarkably low risks of operative mortality.

BACKGROUND: This study aimed to evaluate the performance of the Society of Thoracic Surgeons (STS) risk model and European System for Cardiac Operative Risk Evaluation (EuroSCORE) II for patients undergoing anaortic off-pump coronary artery bypass grafting (OPCAB). METHODS: From January 2010 to June 2017, 1,048 patients (isolated anaortic OPCAB: 1,043, on-pump conversion:5) undergoing isolated anaortic OPCAB were enrolled. The STS risk score and EuroSCORE II were calculated with dedicated online

Early and 2-year clinical outcomes between SAVR and CAVR were not different except for a high rate of permanent pacemaker implantation in the SAVR group.

OBJECTIVES: This study compared the clinical outcomes of bovine and porcine bioprosthetic valves based on structural valve deterioration (SVD) and valve haemodynamic deterioration (VHD) in the aortic position. METHODS: From January 1995 to December 2014, patients who underwent aortic valve replacement (AVR) using a bovine pericardial valve or porcine valve were enrolled. SVD and VHD were defined according to the mean transprosthetic gradient and the grade of aortic regurgitation on transthoracic

BACKGROUND: We evaluated the association between tricuspid annular dilatation and the development of moderate or severe tricuspid regurgitation (TR). Additionally, we determined the optimal tricuspid annular dilatation threshold to use as an indicator for tricuspid annuloplasty in patients with less-than-moderate functional TR (FTR). METHODS: Between August 2007 and December 2014, 227 patients with less-than-moderate TR underwent mitral valve surgery without a tricuspid valve (TV) procedure. The

Abstract Background/Introduction Previous observational studies reported that off-label underdosed apixaban might be associated with a higher risk of stroke. However, the real-world clinical practice data on the off-label underdosed apixaban in patients with atrial fibrillation (AF) who meet single dose reduction criteria remains scarce. Purpose This study aimed to evaluate the apixaban dosing pattern in patients with AF who met a single dose reduction criterion. The difference in clinical chara
