Valvular heart disease is a major cause of morbidity and mortality worldwide. Current heart valve prostheses have considerable clinical limitations due to their artificial, nonliving nature without regenerative capacity. To overcome these limitations, heart valve tissue engineering (TE) aiming to develop living, native-like heart valves with self-repair, remodeling, and regeneration capacity has been suggested as next-generation technology. A major roadblock to clinically relevant, safe, and robust TE solutions has been the high complexity and variability inherent to bioengineering approaches that rely on cell-driven tissue remodeling...

INTRODUCTION: Aortic valve replacement (AVR) is the gold standard for the treatment of severe or symptomatic aortic valve stenosis. Less invasive procedures have been developed as an alternative to the conventional technique of full sternotomy approach with stented prosthesis. The Perceval® aortic valve (LivaNova, Milan, Italy) is a sutureless bioprosthesis, of which several reports have shown promising results in terms of mortality, morbidity and hemodynamic performance, especially with a less invasive approach...

BACKGROUND: Minimally invasive aortic valve replacement using upper-hemisternotomy has been associated with improved results compared to full sternotomy aortic valve replacement. Given the likely expansion of transcatheter aortic valve replacement to low-risk patients, we examine contemporary outcomes after full sternotomy and minimally invasive aortic valve replacement in low-risk patients using our 15-year experience. METHODS: Two thousand ninety-five low-risk patients (Society of Thoracic Surgeons Predicted Risk of Mortality score <4) underwent elective isolated aortic valve replacement, including 1,029 (49%) minimally invasive and 1,066 (51%) full sternotomy, from 2002 to 2015...

Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure in which a prosthetic heart valve is placed and expanded within a defective aortic valve. The device placement is commonly performed using two-dimensional fluoroscopic imaging. Within this work, we propose a novel technique to track the motion and deformation of the prosthetic valve in three dimensions based on biplane fluoroscopic image sequences. METHODS: The tracking approach uses a parameterized point cloud model of the valve stent which can undergo rigid 3D transformation and different modes of expansion...

Aortic valve stenosis has become the most prevalent valvular heart disease in developed countries, and is due to the aging of these populations. The incidence of the pathology increases with growing age after 65 years. Conventional surgical aortic valve replacement through median sternotomy has been the gold standard of patient care for symptomatic aortic valve stenosis. However, as the risk profile of patients worsens, other therapeutic strategies have been introduced in an attempt to maintain the excellent results obtained by the established surgical treatment...

OBJECTIVES: Robotic mitral valve replacement (MVR) emerged in the late 1990s as an alternative approach to conventional sternotomy. With the increased use of bioprosthetic valves worldwide and strong patient desire for minimally invasive procedures, the safety and feasibility of robotic MVRs with bioprosthetic valves require investigation. METHODS: Between January 2013 and May 2017, 52 consecutive patients underwent robotic MVRs using the da Vinci Si surgical system (Intuitive Surgical Inc...

OBJECTIVE: Recently, the PARTNER 2A trial reported results of transcatheter aortic valve replacement versus surgical aortic valve replacement in 2032 intermediate-risk patients at 2 years. Two hundred thirty-six patients (24%) required an access route other than transfemoral. Compared with transfemoral and surgical aortic valve replacement, nontransfemoral transcatheter aortic valve replacement was associated with a numerically higher rate of death and disabling stroke at 30 days. This underscores the need for a better alternative surgical approach for patients with marginal femoral access...

The field of minimally invasive cardiac surgery has undergone rapid transformation over recent years. In this review, we provide a summary of the most current evidence supporting the use of minimally invasive aortic and mitral valve replacement techniques, as well as transcatheter approaches for aortic and mitral valve disease. As an adjunct, the use of robotically assisted coronary bypass surgery and hybrid coronary revascularization procedures is discussed. In order to obtain optimal patient outcomes, a collaborative, heart-team approach between cardiac surgeons and interventional cardiologists is necessary...

BACKGROUND: Balloon Aortic valvuloplasty (BAV) is considered as a bridge therapy to percutaneous valve implantation or a palliative treatment in patients with aortic valve stenosis (AVS). Potential risk of complications, in particular in fragile patients, is still not negligible. AIM: To describe the technique and outcomes of modified BAV in fragile symptomatic patients unsuitable for other treatments using no-pacing and minimally invasive approach. METHODS: Symptomatic fragile patients with severe aortic valve stenosis judged unsuitable by the heart team for surgical or percutaneous valve implantation from 1 September 2013 to 1 September 2017 were offered modified BAV...

PURPOSE: Annular suture placement during minimally invasive right anterior thoracotomy aortic valve replacements (MI-AVR) can be challenging. We present the early clinical experience with novel automated suturing technology that may reduce the technical difficulty of this operation. DESCRIPTION: The technology presented involves an automated articulating suturing device that simultaneously drives dual-curved needles through the aortic annulus to place a pledgeted horizontal mattress suture remotely; a second device with 2 straight needles places suture through the sewing cuff of a prosthetic heart valve...

Here, we demonstrate bilateral pulmonary vein isolation using a bipolar clamp but without atriotomy during minimally invasive aortic valve replacement. The operation was performed through a right anterolateral minithoracotomy. The right pulmonary veins were ablated by using a radiofrequency clamp on the beating heart. After cardiac arrest, the ascending aorta was pulled up using umbilical tape passed through the transverse sinus. Appendage resection offered fine exposure around the lower pulmonary vein. The bipolar clamp was introduced into the oblique sinus under the aorta, and the left pulmonary veins were ablated...

We sought to describe the acute results and short- to medium-term durability of transcatheter tricuspid valve-in-valve (TVIV) implantation within surgical bioprostheses among patients with Ebstein anomaly (EA). Cases were identified from a voluntary, multicenter, international registry of 29 institutions that perform TVIV. Demographic, clinical, procedural, and follow-up data were analyzed. Eighty-one patients with EA underwent TVIV from 2008 to 2016. Thirty-four patients (42%) were New York Heart Association (NYHA) class 3/4 at time of TVIV...

Mitral regurgitation (MR) is the one of the most frequent valvular heart diseases in the developed world, often requiring surgical correction. Degenerative MR is the most common type of non-ischemic, organic MR in the western world. Since no medical treatment has been shown to be effective in preventing the consequences of volume overload in asymptomatic degenerative MR, risk stratification is essential. Currently, this is achieved using clinical and precisely quantified echocardiographic parameters, with newer technologies like cardiac magnetic resonance gaining increasing prominence...

BACKGROUND: Contemporary options for aortic valve replacement (AVR) include transcatheter and surgical approaches (TAVR and SAVR). As evidence accrues for TAVR in high and intermediate risk patients, some clinicians advocate that all patients aged over 80 years should only receive TAVR. Our aim was to investigate the utility of SAVR and minimally invasive AVR (mAVR) among octogenarians in the current era of TAVR. METHODS: From 2002 to 2015, 1,028 octogenarians underwent isolated AVR; 306 TAVR and 722 SAVR, of which 378 patients underwent mAVR...

Mitral valve disease is highly prevalent and quickly leads to development of severe heart failure. Mitral valve disease of degenerative or ischemic etiology affects 7.5 and 9.3% of population older than 65 and 75 years, respectively. "Open" (with cardiopulmonary bypass) surgical repair or valve replacement are not possible in almost half of affected patients because of their complications and concomitant diseases responsible for extremely high risk of these interventions. In the last decade, minimally invasive endovascular technology - transcatheter aortic valve implantation (TAVI) - has been widely introduced for correction of aortic valve disease in similar category of patients...

Rapid-deployment valves could potentially reduce cross-clamping time and cardiopulmonary bypass time in complex combined procedures and facilitate minimally invasive surgery. This propensity-matched study compared clinical and echographic outcomes between patients undergoing rapid-deployment aortic valve replacement (RDAVR) compared with stented biological aortic valve replacement (SAVR), with or without concomitant procedures. Between 2012 and 2015, 61 consecutive patients (age 70 ± 7 years, European System for Cardiac Operative Risk Evaluation [EuroSCORE] II 2...
