BACKGROUND: Baseline comorbidities including renal dysfunction are frequently found in patients treated with transcatheter aortic valve replacement (TAVR) and may increase the risks of acute kidney injury (AKI), although some of them may actually improve renal function. We aimed to evaluate the potential of TAVR to acutely improve post-procedure renal function. METHODS: This is a prospective single-center registry of consecutive patients with severe symptomatic aortic stenosis treated by transfemoral TAVR...

To evaluate the awareness and knowledge of the German population regarding diseases in general, a survey of 1446 people aged 60 years or older was conducted in 14 German towns. The focus was on heart valve diseases with special emphasis on aortic valve stenosis (AS). While cancer was the disease that respondents were most concerned about (25.2%), only 3.3% were concerned about heart valve diseases. In this respect, the knowledge was broadly limited: only 7.4% of participants claimed to have some familiarity with heart valve diseases and only 12...

BACKGROUND: Instantaneous wave-free ratio (iFR) has been used in clinical practice to identify functionally significant stenosis and to guide treatment strategy. However, there are limited clinical data regarding another resting pressure-derived index, resting distal to aortic coronary pressure (Pd/Pa), and similarities and differences between resting Pd/Pa and iFR. OBJECTIVES: The authors investigated the changes in resting Pd/Pa and iFR according to anatomic and hemodynamic stenosis severity and their prognostic implications...

Valve-in-valve implantation is an alternative to reoperation for patients with degenerated bioprostheses. This case report presents a 75-year-old woman presenting with worsening dyspnoea according New York Heart Association (NYHA) Class III after she had received a Sorin Perceval® S sutureless valve due to severe aortic valve stenosis 5 years ago. Echocardiography revealed a degenerated Perceval valve with severe valvular aortic regurgitation and stenosis. After exclusion of acute infective endocarditis, an Edwards SAPIEN 3 was implanted leading to an immediate haemodynamic improvement...

OBJECTIVES: Inefficient aortic flow after the Norwood procedure is known to lead to the deterioration of ventricular function due to an increased cardiac workload. To prevent the progression of aortic arch obstruction, arch reconstruction concomitant with second-stage surgery is recommended. The aim of this study was to determine the indications for reconstruction based on numerical simulation and to reveal the morphology that affects the haemodynamic parameters. METHODS: Fifteen patients who underwent the Norwood procedure or arch repair and Damus-Kaye-Stansel anastomosis were enrolled...

OBJECTIVES: In patients with severe carotid artery stenosis, the anatomy of their Type III aortic arch increases the difficulty and complication rates during carotid artery stenting because of its tortuosity and sharp angulation for cannulation as well as the unstable support of the guidewire for shuttle sheath delivery. METHODS: We demonstrate a novel technique to overcome these challenges, namely the creation of stable innominate artery access by inserting a through-and-through body floss wire from the right brachial artery to the femoral artery...

Transfemoral aortic valve implantation has become an almost routine interventional procedure for severe aortic stenosis in high-risk patients. Over time an increased number of experiences has led to unusual procedures. In this report, we present a successful valve-in-valve transfemoral aortic valve implantation in a patient with aortic regurgitation, who previously had debranching and thoracic endovascular aortic repair operations.

OBJECTIVES: In contrast to stented transcatheter aortic valves, the Direct Flow Medical (DFM) valve is a stentless bovine aortic bioprosthesis mounted in a non-metallic inflatable frame. Hence, severe asymmetric annular calcification may result in residually elevated transaortic pressure gradients after DFM implantation. We present a novel intraprocedural dilatation (IDIL) technique for successful implantation of the DFM valve in the presence of complex annular calcification. METHODS: Between January 2014 and May 2015, 55 patients underwent DFM valve-based transcatheter aortic valve implantation at our institution...

OBJECTIVES: Iliofemoral arteries have been the preferred access for transcatheter aortic valve replacement (TAVR). When these arteries are too small, calcified or tortuous, an alternative access must be considered. Transinnominate (TI) access is an extrathoracic approach that does not require manipulation of major neurovascular structures or the apex. The aim of this study is to evaluate the efficacy and safety of TI TAVR as an alternative access in patients with severe aortic stenosis not amenable to a transfemoral approach...

To explore the clinical and genetic characteristics of Williams-Beuren syndrome (WBS) and to raise awareness of the disease. The characteristics of clinical manifestations, personal history, cardiac ultrasound, brain magnetic resonance imaging (MRI), electroencephalogram (EEG) and chromosome detection results of two cases with WBS were analyzed. The two patients were both male and the age was 11 months and 1 day, and 9 months and 9 days, respectively. They both suffered from cardiovascular malformation: case one presented supravalvular aortic stenosis, and case two showed atrial septal defect and patent ductus arteriosus...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is indicated for patients with aortic stenosis who are intermediate-high surgical risk. Although all-cause mortality rates after TAVI are established, survival attributable to the procedure is unclear because of competing causes of mortality. The aim was to report relative survival (RS) after TAVI, which accounts for background mortality risks in a matched general population. METHODS AND RESULTS: National cohort data (n=6420) from the 2007 to 2014 UK TAVI registry were matched by age, sex, and year to mortality rates for England and Wales (population, 57...

BACKGROUND: Peripheral artery disease (PAD) is associated with increased cardiovascular mortality, and PAD risk factors overlap with those for aortic stenosis. The prevalence and outcomes associated with PAD in a population undergoing transcatheter aortic valve replacement (TAVR) are unknown. METHODS AND RESULTS: Using the Society of Thoracic Surgeons/Transcatheter Valve Therapy Registry linked to Medicare claims data, we identified patients ≥65 years old undergoing TAVR from 2011 to 2015...

BACKGROUND: Bicuspid aortic valves (BAV) are associated with incompletely characterized aortopathy. Our objectives were to identify distinct patterns of aortopathy using machine-learning methods and characterize their association with valve morphology and patient characteristics. METHODS: We analyzed preoperative 3-dimensional computed tomography reconstructions for 656 patients with BAV undergoing ascending aorta surgery between January 2002 and January 2014. Unsupervised partitioning around medoids was used to cluster aortic dimensions...

Aortic valve intervention (AVI) in patients with a severe aortic stenosis (AS) and a preserved left ventricular ejection fraction (LVEF) is controversial. Mitral annular plane systolic excursion (MAPSE) is an easily acquired metric of left ventricular longitudinal shortening. We sought to investigate if an asymptomatic decrease in MAPSE preceded the need for AVI in asymptomatic patients with AS and a preserved LVEF. In this retrospective cohort study, we identified 205 consecutive patients (56% male, 73 ± 11 years) with at least a moderate AS and a normal LVEF who underwent a serial outpatient transthoracic echocardiography (TTE) from 2006 to 2013...

OBJECTIVES: To investigate whether and in which patients with catheter-derived low pressure gradient (PG, <40 mmHg) severe (aortic valve area ≤ 1 cm2) aortic stenosis and preserved left ventricular ejection fraction, early aortic valve replacement (AVR) might improve survival. METHODS: We investigated a total of 506 consecutive patients (age 75 ± 9 years, 58% men) with either moderate aortic stenosis (MAS) or severe aortic stenosis (SAS) and preserved left ventricular ejection fraction (≥50%) as defined at catheterization...

AIMS: Limited information exists describing the results of transcatheter aortic valve replacement (TAVR) in patients with symptomatic severe non-calcific aortic stenosis (AS). METHODS AND RESULTS: We retrospectively identified patients with non-calcific AS who received TAVR with self-expanding transcatheter heart valves in our center. Clinical and echocardiographic outcomes, and post-procedural multi-detector computed tomography (MDCT) measures were compared to patients undergoing TAVR for calcific AS...

A 57-year-old man presented with abdominal pain, hematemesis, and melena. He reported taking high-dose ibuprofen for back pain and drinking several 24-ounce beers daily. Examination was remarkable for icteric sclera, poor dentition, tachycardia, and crescendo-decrescendo murmur at right upper sternal border, radiating to the carotids. Labs revealed leukocytosis, anemia, thrombocytopenia, and elevated liver function tests and INR. Endoscopy demonstrated antral ulcers, duodenitis, and esophagitis. Blood cultures were obtained and broad-spectrum antibiotics started; cultures later grew Streptococcus mitis, and antibiotic coverage was narrowed...
