Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

AIMS: Paediatric patients with mitral valve (MV) disease have limited options for prosthetic MV replacement. Based on a long experience with the stented bovine jugular vein graft (Melody Valve) in the right ventricular outflow tract, we tested the use of the Melody Valve as a surgical implant in the mitral position in patients with congenital mitral disease. METHODS AND RESULTS: Eight patients, age 3 months to 6.2 years, with congenital MV dysplasia had undergone Melody valve implantation in mitral position between March 2014 and October 2015...

BACKGROUND: The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known. AIM: To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital. METHODS: From 1997 to 2009, 107 patients underwent the Ross procedure (mean age: 30±11 years; 69% men; 21 aged<18 years), and were followed for echocardiographic homograft stenosis (peak gradient>36mmHg) and surgical or percutaneous homograft reintervention...

In patients with a small aortic root undergoing aortic valve replacement (AVR), the Freedom SOLO bioprosthesis may be the ideal prosthesis because of its stentless design and supra-annular implantation. This study investigated if the stentless Freedom SOLO has an advantage when compared with a stented bioprosthesis in patients with a small aortic root. From April 2005-July 2014, 269 consecutive patients underwent AVR with either a Freedom SOLO (n = 76) or Mitroflow (n = 193) bioprosthesis size 19mm or 21mm, respectively...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

OBJECTIVES: The aim of this study was to evaluate the long-term performance of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) through longitudinal echocardiographic analysis. BACKGROUND: The long-term performance of the SAPIEN TAVR is not well-described. Therefore, we examined the hemodynamic and valvular profile of the SAPIEN TAVR over 5 years. METHODS: All patients receiving TAVR or SAVR with first post-implant (FPI) and 5-year echoes were analyzed for aortic valve (AV) peak velocity, AV mean gradient, AV area, peak left ventricular (LV) outflow tract and in-stent velocities, Doppler velocity index, aortic regurgitation (AR), LV mass index, stroke volume index, and cardiac index...

AIMS: Pre- and post-evaluations of implantable cardiac devices require innovative and critical testing in all phases of the design process. The Visible Heart(®) Project was successfully launched in 1997 and 3 years later the Atlas of Human Cardiac Anatomy website was online. The Visible Heart(®) methodologies and Atlas website can be used to better understand human cardiac anatomy, disease states and/or to improve cardiac device design throughout the development process. METHODS AND RESULTS: To date, Visible(®) Heart methodologies have been used to reanimate 75 human hearts, all considered non-viable for transplantation...

Coronary artery stenosis is a potentially life-threatening complication after heart valve surgery. The details are presented of a patient with unobstructed coronary arteries, who underwent routine aortic valve replacement and developed dissection of the right coronary artery (RCA) on the third postoperative day, and occlusion of the left anterior descending (LAD) artery one month after surgery. This complication required prompt clinical recognition and diagnosis by repeat coronary angiography, and a rapid intervention with coronary artery bypass grafting or with angioplasty and stenting...

BACKGROUND: Aortic regurgitation (AR) is a frequent and life-limiting complication after transcatheter aortic valve implantation (TAVI). The study aim was to relate post-TAVI AR, using a self-expandable stent, to detailed baseline anatomical and morphological characteristics of the native aortic valve. METHODS: A total of 82 patients (40 males, 42 females; mean age 80 ± 7 years) who received a Medtronic CoreValve implant was included. Aortic root morphology, aortic annulus and implant size mismatch, implant position, extent of aortic annulus and leaflet calcification, the connected sub-annular calcification volume, and their distribution were quantified based on computed tomography scan analysis...

Perventricular Melody valve placement has been described as a bailout approach or alternative RVOT approach in patients >30 kg. We present three patients <20 kg and two patients with limited venous access, where we electively performed the perventricular approach. Retrospective analysis of patients <30 kg and vascular access limitation undergoing elective hybrid pulmonary valve replacement were reviewed. The subcostal approach was performed without sternotomy with the sheath introduced through the diaphragmatic surface of the right ventricle...

BACKGROUND: Bioengineered living autologous valves with remodeling and growth capacity represent a promising concept for future cardiac and venous valve repair. A meticulous understanding of the mechanisms involved in recellularization and remodeling is essential for the safe and efficient clinical translation of this technology. In this context, the first investigations of bioengineered vascular grafts in immune-incompetent or transgenic rodents represented an important step. However, the in-vivo assessment of bioengineered synthetic scaffold-based (biodegradable) valve replacements in rodent models has not been achieved to date...

Trifecta is a stented bioprosthetic heart valve with a bovine pericardial sheet externally mounted on a titanium stent. This valve is applied only for aortic valve replacement (AVR), providing excellent hemodynamics and extremely low incidence of structural valve deterioration (SVD). A 76-year-old woman presented with dyspnea on effort 24 months after AVR with a 21-mm Trifecta valve. Echocardiography revealed severe aortic regurgitation with prolapse of a cusp of Trifecta valve, which suggested that she developed acute heart failure due to early SVD...
