The Transcatheter Valve Therapy Registry has been very helpful in providing data to better understand patient risk factors for transcatheter aortic valve replacement (TAVR). The outcome of TAVR depends on many patient indicators, some of which are given in this article, including the age, dependence on oxygen, classification of pulmonary disease, gender, and the speed of walking. Patient characteristics also help determine which approach will be used to place the device. There are models for the outcome of the TAVR procedure now and more being developed...

BAV in the TAVR era is not well studied BAV resulted in improvements in aortic valve area and transvalvular pressure gradient, and in patients with impaired left ventricle function, ejection fraction improved. These improvements diminished over time, but at one year were still improved compared to baseline. BAV resulted in changes of planned therapy more than half of the patients treated as bridge for TAVR did not ultimately undergo TAVR twice as many planned as bridge for surgical valve replacement actually had surgical valve replacement...

OBJECTIVES: To evaluate the impact of the angles quantified by multidetector computed tomography (MDCT) between the ascending aorta's long axis and, the left ventricular inflow long axis (LVLA), or the left ventricule outflow tract long axis, and the occurrence of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR). METHODS: We prospectively included 136 consecutive patients who underwent a transfemoral TAVR with a preoperative MDCT. The groups were defined according to AR <2 or ≥2 assessed by echocardiography at 1 month...

OBJECTIVES: The aims of this study were to determine plasma elevations of biomarkers of myocardial injury associated with transfemoral (TF) transcatheter aortic valve replacement (TAVR) and to evaluate their prognostic value. BACKGROUND: Increases in biomarkers of myocardial injury are a common finding after TAVR, but their clinical significance is unclear. METHODS: In 756 consecutive TF TAVR patients, cardiac high-sensitivity troponin I (hsTnI) and creatine kinase MB (CK-MB) levels were measured at pre-defined time points to assess the occurrence of myocardial injury (defined as 15 times the upper reference limit for hsTnI [≥1...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has been suggested as a less invasive treatment for high-risk patients with aortic valve disease. In this study, we compared the outcomes of conventional surgical aortic valve replacement (AVR) and TAVR in elderly patients aged over 80. METHODS: A total of 108 patients aged 80 years or older who underwent isolated AVR (n=35) or TAVR (n=73) from 2010 through 2015 at Asan Medical Center were identified. Early and late clinical outcomes, including echocardiographic findings, were evaluated in both groups...

The definition of severe aortic stenosis has classically and retrospectively been based on the natural history of patients with medically managed aortic stenosis and preserved left ventricular function in an era where surgical aortic valve replacement was the sole therapy. We now recognize that this disease is more heterogeneous and includes important subsets of patients with low stroke volume index (low flow) and low-gradient with reduced (classical) or preserved (paradoxical) ejection fraction. These patients pose diagnostic and treatment dilemmas, requiring a comprehensive assessment with integration of multimodality imaging, testing, and clinical assessment...

BACKGROUND: Pre-existing chronic kidney disease (CKD) portends adverse outcomes following heart valve surgery. However, only limited and conflicting evidence is available on the impact of CKD on outcomes following transcatheter aortic valve replacement (TAVR). The objective of this review was to evaluate the effect of pre-existing CKD on TAVR outcomes. METHODS: We performed a systematic electronic search using the PRISMA statement to identify all randomized controlled trials and observational studies investigating the effect of pre-existing CKD on outcomes following TAVR...

Transthoracic (transapical and transaortic) access is inferior compared with femoral artery access. Percutaneous transcaval aortic access is a reasonable alternative approach that is being used in transcatheter aortic valve replacement (TAVR) in patients with poor iliofemoral anatomy. Duplicated Inferior vena cava (DIVC) is an uncommon abnormality. We report the case of 76-year-old lady with history of severe peripheral vascular disease, morbid obesity, diabetes, hypertension, hyperlipidemia and duplicated IVC that had severe symptomatic aortic stenosis...

BACKGROUND: We sought to describe an optimized approach to coronary artery disease (CAD) screening and management in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: When invasive coronary angiography showed CAD, the treatment strategy and completeness of revascularization was determined based on coronary anatomy. TAVR was performed in the same setting if percutaneous coronary intervention (PCI) was uncomplicated; otherwise TAVR was postponed...

Several options are available to address hemostasis at the end of a cardiac catheterization or percutaneous transfemoral transcatheter aortic valve replacement (TAVR) when conventional options are ineffective. To date, there have been few studies exploring the use of a topical thrombin preparation, as one of its main contraindications is that it cannot be used intravascularly due to risk of embolization. The following case shows safe utilization of Surgiflo hemostatic gel matrix under fluoroscopic guidance against an inflated balloon in order to achieve closure of a fistulous tract from a femoral artery access site during percutaneous TAVR...
