AIMS Reduced stroke volume index (SVI) in patients with severe aortic stenosis (AS) and preserved ejection fraction (EF) is associated with adverse outcomes even after aortic valve replacement (AVR), although specific reasons for impaired survival in this group are unknown. We investigated predictors of post-AVR survival and specific cause of death in patients with AS according to SVI. METHOD...
BACKGROUND Patients with severe aortic stenosis (AS) who were deemed too high risk or inoperable for conventional aortic valve replacement (AVR) in the PARTNER (Placement of Aortic Transcatheter Valves) trial were randomized to transcatheter aortic valve replacement (TAVR) versus AVR (PARTNER-A arm) or standard therapy (PARTNER-B arm). OBJECTIVES This study compared when and how deaths occurr...
BACKGROUND In compensated aortic stenosis (AS), cardiac performance measured at the ventricular chamber is typically supranormal, whereas measurements at the myocardium are often impaired. We investigated intramyocardial mechanics after aortic valve replacement (AVR) and the effects relative to the presence or absence of coronary artery disease (CAD+ or CAD-), respectively. METHODS AND RESULT...
Aortic valve replacement (AVR) is the only effective treatment for symptomatic aortic stenosis (AS). In the ideal candidate, the operative mortality associated with AVR is 4%.1 With increasing age, patients with AS acquire other comorbidities that increase their surgical risk to prohibitive levels, limiting their surgical options. It is estimated that at least 30% of the patients with severe AS...
OBJECTIVE To develop a multivariable logistic risk model for predicting early mortality following aortic valve replacement (AVR) in adults, and to compare its performance against existing AVR-dedicated models. METHODS Prospectively collected data from the Australasian Society of Cardiac and Thoracic Surgeons (ASCTS) database project were used. Thirty-five preoperative variables from AVR liter...
BACKGROUND Aortic Valve Replacement (AVR) is usually done through median sternotomy. The present study aimed to compare the right anterolateral thoracotomy and median sternotomy approaches for AVR. MATERIALS AND METHODS The present prospective study was conducted on 60 patients who had aortic valve disease and were subjected to AVR. Thirty patients underwent aortic valve replacement via right...
Aortic valve replacement (AVR) is recommended as a standard surgical procedure for aortic valve disease. Still the evidence for commonly claimed predictors of post-AVR prognosis, in particular mortality, appears scant. This systematic review reports on the evidence for predictors of post-AVR mortality, and may be helpful in pre-surgical risk-stratification. In PubMed, we searched for original r...
BACKGROUND The influence of prosthesis-patient mismatch (PPM) on survival after aortic valve replacement (AVR) remains controversial. In this study, we sought to determine the effect of PPM on early (≤30 days) and late mortality (>30 days) after AVR or AVR combined with coronary artery bypass grafting (AVR with CABG). METHODS Between January 1998 and March 2012, 2976 patients underwent AVR (n...
Aortic dissection (AD) in patient with prostetic aortic valve is a rare but potentially fatal complication. Predictors of the occurrence of AD after aortic valve replacement (AVR) include fragility and thinning of the ascending aorta, aortic dilatation, aortic regurgitation (AR) and high blood pressure before AVR operation. AD is usually symptomatic, but rarely asymptomatic.We presented a case ...
