A new controversy is raising in cardiovascular surgery, whether or not the new generation transcatheter valves used for valve implantation are superior to surgical techniques used for traditional valve replacement. If such a debate is far from being an issue for mitral valve treatment, where minimal invasive, (robotic or video-assisted) mitral valve repair has become the gold standard for mitral valve treatment while transcatheter mitral valve solutions are lagging behind(1-4), there are many voices stating that the future of aortic valve treatment will mainly be transcatheter(5)...

OBJECTIVES: The objective was to design sizing rings that would enable proper sizing of the graft in reimplantation procedures and to perform leaflet repair before graft implantation. METHODS: The rings were designed in Autodesk Fusion 360 (San Rafael, CA, USA) and 3D printed using a commercial online 3D printing service. We designed incomplete rings with a low profile and complete rings with a high profile. The complete rings are best suited for reimplantation procedures, whereas low profile C rings are intended for isolated aortic valve repair, where the ascending aorta is not transected...

We report the long-term outcomes of a 12-year-old boy who underwent bicuspidization of a severely stenotic unicuspid aortic valve with CorMatrix small intestinal submucosal extracellular matrix (CorMatrix Cardiovascular, Roswell, GA). CorMatrix supported favorable immediate surgical and echocardiographic outcomes and maintained stable growing functional dynamics for 2 years. At 52.5 months in situ, however, the valve failed with severe calcification, fibrosis, and retraction necessitating a redo operation. Reconstructive operations with CorMatrix are feasible, but this result questions its capacity for constructive remodeling in left-sided valve repair...

OBJECTIVES: Bicuspid aortic valve (BAV) is the most common congenital valvular abnormality and frequently presents with accelerated calcific aortic valve disease, requiring aortic valve replacement (AVR) and thoracic aortic aneurysm and dissection. Supporting evidence for Association Guidelines of aortic dimensions for aortic resection is sparse. We sought to determine whether concurrent repair of dilated or aneurysmal aortic disease during AVR in patients with BAV substantially improves morbidity and mortality outcomes...

Importance: Identifying high-performing surgical valve centers with the best surgical outcomes is challenging. Hospital surgical volume is a frequently used surrogate for outcomes. However, its ability to distinguish low-performing and high-performing hospitals remains unknown. Objective: To examine the association of hospital procedure volume with hospital performance for aortic and mitral valve (MV) surgical procedures. Design, Setting, and Participants: Within an all-payer nationally representative data set of inpatient hospitalizations, this study identified 682 unique hospitals performing surgical aortic valve replacement (SAVR) and MV replacement and repair with or without coronary artery bypass grafting (CABG) between 2007 and 2011...

The cardiac catheterization laboratory is advancing medicine by performing procedures on patients who would usually require sternotomy and cardiopulmonary bypass. These procedures are done percutaneously, allowing them to be performed on patients considered inoperable. Patients have compromised cardiovascular function or advanced age. An anesthesiologist is essential for these procedures in case of hemodynamic compromise. Interventionalists are becoming more familiar with transcatheter aortic valve replacement and the device has become smaller, both contributing to less complications...

BACKGROUND: Chromogranin B (CGB) regulates B-type natriuretic peptide (BNP) production. Circulating CGB levels are elevated in heart failure (HF) animal models and HF patients, but also increase in healthy individuals in response to physical activity. Therefore, CGB seems to integrate information from myocardial stress and systemic neuro-endocrine activation. Substantial gaps remain in our understanding of CGB regulation in HF. METHODS AND RESULTS: We conducted a retrospective registry study including 372 patients...

Bicuspid aortic valve (BAV) is the most common type of congenital heart disease, occurring in 0.5-2% of the population, where the valve has only two rather than the three normal cusps. Valvular pathologies, such as aortic regurgitation and aortic stenosis, are associated with BAVs, thereby increasing the need for a better understanding of BAV kinematics and geometrical characteristics. The aim of this study is to investigate the influence of the non-fused cusp (NFC) angle in BAV type-1 configuration on the valve's structural and hemodynamic performance...

PURPOSE OF REVIEW: Transcatheter valvular interventions have increased in importance and utility for surgical valve repair and replacement. Cardiac imaging is the most crucial aspect of procedural planning and guidance. Echocardiography is a widely used, portable, and dynamic imaging modality used for many of these interventions. This review will summarize the role echocardiography in structural heart valvular interventions. RECENT FINDINGS: Intraprocedural echocardiographic guidance has been a mainstay of structural heart interventions...

Iatrogenic aortic valve (AV) perforation during non-aortic cardiac operations is a rare complication. The suture-related inadvertent injury to an AV leaflet can produce leaflet perforation with aortic regurgitation after ventricular septal defect repair (VSDR). We report three consecutive patients who had iatrogenic aortic leaflet perforation during VSDR in other hospitals and referred to our hospital for reoperation. In all three cases, the perforated AV leaflets were preserved and repaired by autologous pericardial patch or direct local closure...

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: Sinus of Valsalva aneurysms (SVAs) are rare and are often complicated by aortic insufficiency (AI). Treating AI is important for achieving good long-term results in patients with SVA. Here, we have summarized our experience with the surgical management of patients with SVA with concomitant AI. METHODS: Patients who were diagnosed with SVA and underwent surgical treatment between January 2008 and May 2016 were included. Clinical characteristics, including age, gender, SVA anatomy and concurrent anomalies, were analysed...

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: This study aimed to assess mitral valve function after repair of ventricular septal defect (VSD) combined with mitral regurgitation (MR) in the mid-term follow-up period, to evaluate the clinical utility of simultaneous mitral valve repair (MVR). METHODS: From June 2005 to March 2014, 60 patients with VSD and MR underwent surgical treatment. After performing propensity score analysis (1:1) for the entire sample, 46 patients were selected and divided into 2 groups: those with VSD closure and MVR (VSD + MVR, 23 patients) and those with VSD closure without mitral valve intervention (VSD only, 23 patients)...

Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries is considered the most severe end of the tetralogy of Fallot spectrum, whereas complete atrioventricular septal defect associated with tetralogy of Fallot is a rare congenital defect. However, the combination of pulmonary atresia, major aortopulmonary collateral artery and complete atrioventricular septal defect is extremely rare, and surgical repair has not been reported. We describe a successful, 1-stage correction in a 7-month-old boy with this condition, who had an additional complication of a single aortic outlet from the right ventricle and significant atrioventricular valve regurgitation...
