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: 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...

A 53-year-old woman was referred to us for reoperation of aortic root. Twenty-three years ago, she was diagnosed with aortitis and suffered from annuloaortic ectasia, aortic regurgitation, severe stenosis of left carotid and subclavian arteries and occulusion of the main trunk of left coronary artery. The left coronary system was perfused by collateral arteries from right coronary artery. She had undergone original Bentall procedure( Cooley graft 26 mm+SJM valve 25 mm) with coronary artery bypass grafting (CABG)[saphenous vein graft (SVG)-left anterior descending artery (LAD)]...

Risk-benefit assessment for transcatheter aortic valve implantation (TAVI) is still evolving. A sizeable group of patients do not fully benefit from intervention despite a technically successful procedure. All patients who underwent TAVI with device success and with no Valve Academic Research Consortium (VARC)-2 defined complications were included. Various demographic data, clinical details, and echocardiographic findings were examined. The outcome was defined as 1-year composite of mortality, stroke, lack of functional-class improvement (by New York Heart Association class), and readmissions (≥1 month after the procedure)...

The prevalence and prognostic implications of ventricular conduction disturbances in aortic stenosis (AS) have not been extensively evaluated. The present retrospective study investigated the prevalence and prognostic implications of ventricular conduction abnormalities (including the QRS morphology and duration) in AS. A total of 1,245 patients (mean age 66 ± 14 years, 62.8% men) with varying AS severity (aortic sclerosis 33.9%, mild AS 11.5%, moderate AS 29.9%, and severe AS 24.7%) were evaluated. Demographic, clinical variables, and presence of ventricular conduction abnormalities on the electrocardiogram (based on QRS morphology and duration) were related to occurrence of all-cause mortality, correcting for occurrence of aortic valve replacement...

BACKGROUND: Morphometric measurements of systemic atherosclerosis and direct quantification of visceral fat are only possible using materials from autopsy studies. However, the few autopsy studies that have investigated the association of visceral fat with atherosclerosis had small sample sizes and focused on coronary arteries of young or middle-aged White subjects. We aimed to investigate the association of pericardial fat (PF) and abdominal visceral fat (AVF) with atherosclerosis in the aorta, coronary, carotid, and cerebral arteries in a large autopsy study...
