The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

While the long-term outcome of surgical aortic valvotomy (SAV) appears to be better than that of balloon aortic valvuloplasty (BAV) as the primary procedure of aortic valve stenosis, the surgical strategies and techniques of treating aortic valve disease in children in other situations remain controversial. Valve repair should be first considered while replacement is still unavoidable in some cases, and new repair techniques developed by innovative surgeons are gradually becoming adopted. Some complex repair procedures such as cusp extension, leaflet replacement/reconstruction have provided satisfactory outcomes...

Severe aortic stenosis (AS) is considered a contraindication to the use of mechanical circulatory support (MCS) devices, including the Impella heart pump (Abiomed, Aachen, Germany). We describe a case in which a 72-year-old female with severe AS and peripheral vascular disease (PVD) presented with retractable ischemia in the setting of a non-ST elevation myocardial infarction (NSTEMI). Using a coordinated multidisciplinary approach, our case is the first to combine iliac angioplasty, balloon aortic valvuloplasty (BAV), and the insertion of an Impella CP device in the setting of severe AS to facilitate successful coronary artery revascularization in a non-surgical patient...

BACKGROUND: The approach to intervention for congenital aortic valve stenosis (AS) differs depending upon centre bias toward a primary catheter or surgical approach. We therefore investigated associations with freedom from re-intervention (FFI) in the cohort of children who underwent primary balloon aortic valvuloplasty (BAV) for congenital AS in our centre. METHODS: All patients who underwent BAV as a primary procedure in the period between 2001 and 2015 in a single service were included...

Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) has been established as a safe and effective means of treating failed surgical bioprosthetic valves (BPVs) in patients at high risk for complications related to reoperation. Patients who undergo VIV TAVR are at risk of patient-prosthesis mismatch, as the transcatheter heart valve (THV) is implanted within the ring of the existing BPV, limiting full expansion and reducing the maximum achievable effective orifice area of the THV. Importantly, patient-prosthesis mismatch and high residual transvalvular gradients are associated with reduced survival following VIV TAVR...

Predilatation has been historically considered a mandatory step before transcatheter aortic valve implantation (TAVI) since it facilitates valve crossing and prosthesis delivery, ensures optimal valve expansion and improves hemodynamic stability during valve deployment. However, as a result of procedural evolution over time, direct TAVI (without pre-implantation balloon aortic valvuloplasty) has emerged as an interesting option to simplify the procedure and to avoid potential valvuloplasty-related complications...

: The introduction of percutaneous treatment of severe aortic stenosis with transcatheter aortic valve implantation (TAVI) remains one of the greatest achievements of interventional cardiology. In fact, TAVI emerged as a better option than either medical therapy or balloon aortic valvuloplasty for patients who cannot undergo surgical aortic valve replacement (SAVR) or are at high surgical risk. Recently, increased operator experience and improved device systems have led to a worldwide trend toward the extension of TAVI to low-risk or intermediate-risk patients...

OBJECTIVES: The authors sought to study variation in the practice of balloon aortic (BAV) and pulmonary valvuloplasty (BPV). BACKGROUND: The IMPACT (IMProving Adult and Congenital Treatment) registry provides an opportunity to study practice variation in transcatheter interventions for congenital heart disease. METHODS: The authors studied BAV and BPV in the IMPACT registry from January 1, 2011, to September 30, 2015, using hierarchical multivariable models to measure hospital-level variation in: 1) the distribution of indications for intervention; and 2) in cases with "high resting gradient" as the indication, consistency with published guidelines...

We report a case of aortic valve infective endocarditis (IE) in a 24-year-old man with atopic dermatitis (AD). He had a history of balloon valvuloplasty for a stenotic bicuspid aortic valve, and had dental caries but no invasive dental procedure before the onset of IE. On admission, skin lesions of AD with itching and scratches were found on the neck, trunk, and extremities. Echocardiography showed a vegetation on the aortic valve with mild steno-regurgitation, but extension of IE to the annulus was not detected...

BACKGROUND: Aortic stenosis has been reported to manifest a slow rate of progression in mild disease, with a greater likelihood of progression in patients with moderate-severe disease. The natural history of the Doppler-estimated maximum gradient (DEMG) in patients after balloon aortic valvuloplasty (BAVP) has not previously been studied on a large scale. METHODS AND RESULTS: A retrospective review was performed of 360 patients from 1984 to 2012 with aortic stenosis, providing a total of 2059 echocardiograms both before and after BAVP...

Transcatheter aortic valve implantation (TAVI) is an effective and less invasive treatment for the increasing population of individuals with severe aortic stenosis (AS). Echocardiography is crucial in the assessment of AS patients from pre- to post-procedure. Transthoracic echocardiography (TTE) may be used to assess patient suitability for TAVI, as well as evaluate the severity of AS, the aortic valve complex, aortic valve morphology, mitral regurgitation (MR), and left ventricular function. Transesophageal echocardiography (TEE) is usually used as an intra-procedural monitoring tool to provide feedback during the procedure, to assess prosthetic valve function, and to detect complications rapidly before and after balloon aortic valvuloplasty (BAV) or transcatheter heart valve (THV) deployment...

OBJECTIVES: The technique of subcoronary autograft implantation for the Ross procedure has shown excellent durability of aortic valve function in adults. However, its use in children with hypoplastic aortic annulus or multilevel left ventricular outflow tract obstruction (LVOTO) was traditionally precluded. We combined this technique with a Konno incision and evaluated LVOTO relief and durability of the autograft function in growing patients. METHODS: Between January 2012 and January 2017, 13 patients with severe LVOTO and hypoplastic aortic annulus underwent Ross-Konno procedure with subcoronary autograft implantation...

Patient-specific computational models are an established tool to support device development and test under clinically relevant boundary conditions. Potentially, such models could be used to aid the clinical decision-making process for percutaneous valve selection; however, their adoption in clinical practice is still limited to individual cases. To be fully informative, they should include patient-specific data on both anatomy and mechanics of the implantation site. In this work, fourteen patient-specific computational models for transcatheter aortic valve replacement (TAVR) with balloon-expandable Sapien XT devices were retrospectively developed to tune the material parameters of the implantation site mechanical model for the average TAVR population...

The Impella is a mechanical circulatory support device that supports ventricular function. Since 2008, when the first Impella device received Food and Drug Administration clearance, its use has become increasingly prevalent. A variety of Impella devices are available, and are differentiated by size, power, and insertion techniques. These versions of the Impella have been used in a multitude of clinical scenarios, both emergent and elective, including high-risk coronary interventions, acute myocardial infarction complicated by cardiogenic shock, decompensated left and right heart failure, high-risk ventricular tachycardia ablations, and aortic valvuloplasty...
