BACKGROUND: In the evolving field of transcatheter aortic valve replacements a new generation of valves have been introduced to clinical practice. With the complexity of the TAVR procedure and the unique aspects of each TAVR device, there is a perceived risk that changing or adding a new valve in a department could lead to a worse outcome for patients, especially during the learning phase. The objective was to study the safety aspect of introducing a second generation repositionable transcatheter valve (Boston Scientific Lotus valve besides Edwards Sapien valve) in a department...

BACKGROUND: Two-dimensional (2D) echocardiography is one of the most feasible, noninvasive methods for assessing the aortic diameter and biomechanical changes. We studied possible interfaces between noninvasive biomechanical and speckle-tracking (ST) echocardiographic data from dilated aortas. METHODS: Altogether, 44 patients with dilative pathology of ascending aorta (DPAA) were compared with subjects without ascending aortic dilation (diameter <40 mm). DPAA patients formed two groups based on diameter size: group 1, ≤45 mm diameter; group 2, >45 mm...

RATIONALE: Drug-induced valvular heart disease (DI-VHD) remains an under-recognized entity. PATIENT CONCERNS: This report describes a heart valve replacement which was complicated by intractable systemic pulmonary arterial hypertension in a 61-year-old female with severe restrictive mitral and aortic disease. The diagnosis of valvular disease was preceded by a history of unexplained respiratory distress. The patient had been exposed to benfluorex for 6.5 years. DIAGNOSES: The diagnostic procedure documented specific drug-induced valvular fibrosis...

A woman underwent ascending aortic aneurysm repair, aortic root and valve replacement, and coronary artery bypass grafting. Her postoperative course was complicated by stroke and status epilepticus. With supportive care and antiepileptics, her neurologic status improved. Intravenous heparin and aspirin were initiated. On postoperative day 13, she developed a large retroperitoneal hematoma with femoral neuropathy. Because her hematoma was not amenable to percutaneous drainage or surgical evacuation, and considering her comorbidities, a conservative approach was elected...

Remodelling in the atria could appear as a result of hypertension, diabetes or ischaemic heart disease. Galectin-3 (Gal-3) is a mediator of profibrotic pathways and a potential biomarker of cardiac remodelling. We prospectively recruited consecutive patients undergoing elective cardiac surgery. Preoperative Gal-3 levels were determined from serum samples, and the presence of fibrosis was assessed from atrial appendage tissue samples obtained during cardiac surgery. We included 100 patients with aortic valve or ischaemic heart diseases and 15 controls with permanent AF...

Low immunogenicity and high repopulation capacity are crucial determinants for the functional and structural performance of acellular cardiovascular implants. The present study evaluates a detergent-free, non-proteolytic, actin-disassembling regimen (BIO) for decellularization of heart valve and vessel grafts, particularly focusing on their bio-functionality. Rat aortic conduits (rAoC; n = 89) and porcine aortic valve samples (n = 106) are decellularized using detergents (group DET) or the BIO regimen...

INTRODUCTION: Aortic stenosis (AS) is more than only a degenerative disease, it could be also an atherosclerotic-like process involving the valve instead of the vessels. Little is known about the relation of arterial stiffness and AS. AIM: We sought to determine wether pulse wave velocity (PWV), is related to AS severity and to the procedures response, both as surgical aortic-valve-replacement (AVR) and trascatheter-aortic-valve-implantation (TAVI). METHODS: 30 patients with severe AS were treated (15 AVR, 15 TAVI)...

AIMS: We analysed the number of procedures, indications, and in-hospital mortality rates of all patients undergoing isolated surgical aortic valve replacement (sAVR) or transvascular (TV-) and transapical (TA-) transcatheter aortic valve implantation (TAVI) from 2012 to 2015 in Germany. METHODS AND RESULTS: More than 31,000 aortic valve procedures were performed in 2015 in Germany, representing a total increase of 4.5% over 2014. TV-TAVI accounts for 13,108 of these procedures, with an increase of 21%, whereas the numbers of isolated sAVR and TA-TAVI decreased slightly...

Blood transfusions are considered as an important predictor of adverse outcome in patients with severe aortic (AS) undergoing transcatheter aortic valve implantation (TAVI). We sought to investigate the association between blood transfusions and mortality after TAVI. We enrolled 101 consecutive patients with severe AS undergoing TAVI. Patients who required transfusion were defined as patients in whom at least one unit of packed red blood cells (PRBCs) was transfused in the perioperative period. Twelve-month outcomes were assessed based on Valve Academic Research Consortium definitions...

AIMS: Quantitative mitral regurgitation (MR) grading remains challenging. This study evaluated the concept of integrating echocardiography and computed tomography for grading MR severity. Specifically, an integrated parameter was developed that combines the true cross-sectional mitral regurgitant orifice area (ROA) assessed with multi-detector row computed tomography (MDCT) with flow data from echocardiography. METHODS AND RESULTS: Systolic MDCT data of 73 patients, referred for transcatheter aortic valve implantation (TAVI) who also had MR, were evaluated...

Quadricuspid aortic valve (QAV) is a rare congenital heart disease. The functional status of QAV is predominantly a pure aortic regurgitation. Clinical manifestations of patients with a QAV depend on the functional status of the QAV and the associated disorders. Significant valvular regurgitation and (or) stenosis is often present with subsequent operation performed at the fifth to sixth decade of life. The functional status of QAV is predominantly regurgitant; whereas pure stenotic QAV can be as few as in only 0...
