Transcatheter aortic valve implantation (TAVI) has reached relative maturity for the treatment of severe, symptomatic aortic stenosis (AS). TAVI for patients with smaller anatomy is a challenging procedure due to specific anatomical difficulty and complications including annulus rupture and vascular complications. Prevention of these complications, and the introduction of a newer-generation and...
Prosthetic valve endocarditis (PVE) after transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) is a potential life threatening complication. Better understanding of the incidence, predictors, clinical presentation, diagnostic measures, complications and management of PVE may help improve TAVI long-term outcome. We report a case of TAVI-PVE in an 80-year-old...
Results Mean logistic Euroscore was 29.6 for redo-TAVI compared to 18.6 for redo-SAVR (p < 0.05). Type of previous cardiac surgery performed in each redo group is summarised in Table 1. TAVI access was transfemoral (65.5%), transapical (6.7%), or trans-aortic (27.8%). Despite a higher incidence of MACE (major adverse cardiac events) in SAVR patients, results indicated no significant differences...
BACKGROUND Transcatheter aortic valve implantation (TAVI) has been shown to improve prognosis of high-risk patients. Data, however, concerning the impact of TAVI on regional and global left atrial (LA) and left ventricular (LV) mechanics in varying entities of severe aortic stenosis (AS) are sparse, particularly in patients with paradoxical low-flow (PLF) AS or with reduced LV ejection fraction...
BACKGROUND The incidence of clinically apparent stroke in transcatheter aortic valve implantation (TAVI) exceeds that of any other procedure performed by interventional cardiologists and, in the index admission, occurs more than twice as frequently with TAVI than with surgical aortic valve replacement (SAVR). However, this represents only a small component of the vast burden of neurological inj...
BACKGROUND AND OBJECTIVES Transcatheter aortic valve implantation (TAVI) was recently introduced in Korea. The present report describes the experience of early TAVI cases. SUBJECTS AND METHODS Between March, 2010 and October, 2011, 48 patients with severe symptomatic aortic stenosis (AS) were screened at the Asan Medical Center to determine their suitability for surgical intervention. Of thes...
BACKGROUND Early stent valve thrombosis after transcatheter aortic valve implantation (TAVI) is a rare complication, which is diagnosed based on the appearance of clinical symptoms of heart failure and echocardiographic findings. After TAVI, transthoracic echocardiography is performed to assess transcatheter heart valve (THV) function. However, preliminary reports indicate the potential additiv...
Trans-catheter Aortic Valve Implantation (TAVI) is an endovascular treatment for critical aortic stenosis. An early “learning curve” is important drawback of TAVI that can dramatically alter patient safety and hospital costs. There is paucity of data regarding the quantification of learning experience associated with the technique. The aim of this study was to assess learning curve in clinical ...
BACKGROUND Aortic valve stenosis may influence fractional flow reserve (FFR) of concomitant coronary artery disease by causing hypertrophy and reducing the vasodilatory reserve of the coronary circulation. We sought to investigate whether FFR values might change after valve replacement. METHODS AND RESULTS The functional relevance of 133 coronary lesions was assessed by FFR in 54 patients wit...
BACKGROUND This study compared surgical outcomes of patients with previous cardiac surgery undergoing transapical transcatheter aortic valve implantation (PCS-TA-TAVI) with those of patients undergoing transapical transcatheter aortic valve implantation as an initial procedure (initial TA-TAVI) by using propensity analysis. METHODS From January 2005 through January 2013, 267 consecutive high-...
