Right ventricular outflow tract (RVOT) dysfunction is a common hemodynamic challenge for adults with congenital heart disease (ACHD), including patients with repaired tetralogy of Fallot (TOF), truncus arteriosus (TA), and those who have undergone the Ross procedure for congenital aortic stenosis and the Rastelli repair for transposition of great vessels. Pulmonary valve replacement (PVR) has become one of the most common procedures performed for ACHD patients. Areas covered: Given the advances in transcatheter technology, we conducted a detailed review of the available studies addressing the indications for PVR, historical background, evolving technology, procedural aspects, and the future direction, with an emphasis on ACHD patients...

OBJECTIVES: To treat aortic valve disease and concomitant root disease with transcatheter techniques, 'composite graft' implants are required. Our goal was to assess the suitability of the porcine aortic root for transcatheter root repair tests. METHODS: Eight pig hearts explanted from domestic pigs used in experimental surgery were compared to data from the literature on human hearts. The measured diameters included those of the annulus, sinuses of Valsalva, coronary ostia, sinotubular junction, ascending aorta, innominate artery and aortic arch...

Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare complex cyanotic congenital heart disease with heterogeneous morphological variation. Prenatal diagnosis allows for developing a safe plan for delivery and postnatal management. While transthoracic echocardiography allows for detailed delineation of the cardiac anatomy, additional imaging modalities such as computed tomography, magnetic resonance imaging, and catheterization may be necessary to further outline features of the cardiac anatomy, specifically coronary artery anatomy...

BACKGROUND: The Adult Congenital Heart Surgery (ACHS) score was derived from the Society of Thoracic Surgeons Congenital Heart Surgery Database. The score was validated with data of 1,603 operations and reached a good predictive power. We sought to evaluate its predictive power on 1,654 operations performed in 2 European centers. METHODS: Data of all consecutive patients aged 18 years or more, who underwent surgery for congenital heart disease between 2004 and 2013 at Center 1 (n=830), and between 2005 and 2016 at Center 2 (n=824), were collected...

OBJECTIVES: Given the paucity of available literature, we sought to evaluate the mechanisms of tricuspid regurgitation and the outcomes of tricuspid valve surgery in the presence of permanent pacemakers. METHODS: We retrospectively reviewed the records of 622 adult patients who underwent tricuspid valve surgery in the presence of permanent pacemakers between January 1993 and December 2013. Those with prosthetic tricuspid valve or tricuspid valve endocarditis and those undergoing concomitant heart transplant were excluded (n = 23)...

AIMS: Severe tricuspid regurgitation (TR) is common in patients with right-sided heart failure (HF) and causes substantial morbidity and mortality. Treatment options beyond medical therapy are limited for high-risk patients. Transcatheter edge-to-edge tricuspid valve (TV) repair showed procedural safety and short-term efficacy. Impact on mid-term outcome is unclear. This dual-centre observational study evaluates the mid-term safety, efficacy and clinical outcome after edge-to-edge TV repair for severe TR in patients with HF...

OBJECTIVE: To evaluate short-term outcomes following direct aortic root and arch repair in patients with acute type A aortic dissection (ATAAD) without technical adjuncts. METHODS: Between 2012 and 2016, 94 consecutive patients with ATAAD underwent surgical repair, including aortic root repair (n = 45), root replacement (n = 39), or no root procedure (n = 10). Aortic root repair was achieved by running approximation of the dissected aortic wall circumferentially at the sinotubular junction and reinforcing the coronary ostia with 5-0 Prolene...

Objective: Reoperative mitral valve surgery is increasingly required and can be associated with significant morbidity and mortality. The beating heart minimally invasive mitral valve surgery has a proposed benefit in avoiding the risks of repeat sternotomy, with reducing the need for adhesiolysis and cardioplegia reperfusion injury. We describe our experience with such a technique in patients with previous sternotomy. Methods: A retrospective study was performed and all patients undergoing surgery of mitral valve through a right limited thoracotomy without application of an aortic cross-clamp (beating heart) as a redo cardiac surgery between January 2006 and January 2015 were included (n=25)...

The systemic right ventricle (SRV) is commonly encountered in congenital heart disease representing a distinctly different model in terms of its anatomic spectrum, adaptation, clinical phenotype, and variable, but overall guarded prognosis. The most common clinical scenarios where an SRV is encountered are complete transposition of the great arteries with previous atrial switch repair, congenitally corrected transposition of the great arteries, double inlet right ventricle mostly with previous Fontan palliation, and hypoplastic left heart syndrome palliated with the Norwood-Fontan protocol...

A 55-year-old male patient presented with repeated acute retrosternal chest pain. Twelve-lead electrocardiogram and cardiac enzymes revealed non-ST elevation myocardial infarction. He was treated as non-ST elevation myocardial infarction at first. The symptoms of left-sided hemiparesis and aphasia occurred later on after admission. The results of emergent brain computed tomography and magnetic resonance imagining demonstrated acute stroke. The unusual presentation warned us of the possibility of aortic dissection...

OBJECTIVES: This study evaluates the impact of untreated preoperative severe mitral valve regurgitation (MR) on outcomes after left ventricular assist device (LVAD) implantation. METHODS: Of the 234 patients who received LVAD therapy in our centre during a 6-year period, we selected those who had echocardiographic images of good quality and excluded those who underwent mitral valve replacement prior to or mitral valve repair during LVAD placement. The 128 patients selected were divided into 2 groups: Group A with severe MR (n = 65) and Group B with none to moderate MR (n = 63, 28 with moderate MR)...

We report a case of catheter-based edge-to-edge mitral valve repair in a teenage male patient with non-ischaemic cardiomyopathy to improve pulmonary hypertension secondary to severe functional mitral regurgitation (FMR) to defer anticipated heart transplantation. A 19-year-old patient with previous history of fulminant myocarditis followed by markedly left ventricular dysfunction presented with severe mitral regurgitation 3 years after initial recovery. Slightly over time, deterioration of FMR was associated with gradual increase in pulmonary artery pressures despite optimal medical therapy...

Objective: Female sex is a known risk factor for cardiac surgery, and tricuspid valve (TV) disease is more common in women. There are few data on sex-stratified surgical outcomes for isolated TV surgery. An administrative database was used to compare acute in-hospital outcomes between men and women undergoing isolated TV surgery. Methods: Patients aged >18 who underwent TV repair or replacement from 2004 to 2013 were identified using the National Inpatient Sample...

BACKGROUND: Repair of congenital heart defects involving the right ventricular outflow tract may require the implantation of a right ventricle to pulmonary artery conduit. This conduit is likely to be replaced during childhood. This study compares the operative outcomes of the replacement procedure of Contegra® and homografts in pulmonary position. METHODS: From 1999 to 2016, 82 children underwent 87 right ventricle to pulmonary artery conduit replacements (60 Contegra® and 27 homografts)...

A supramitral ring is a rare cause of mitral stenosis, while an isolated mitral valve cleft is a rare cause of congenital mitral regurgitation. Fortunately, both the lesions are known to have good outcomes after surgical correction. Although each is known to be associated with a variety of other structural heart defects, their coexistence has not been reported previously. We report a case of a three- and half-year-old boy detected to have a rare combination of supramitral ring producing severe mitral stenosis with a coexisting cleft in the anterior leaflet of mitral valve causing severe mitral regurgitation...

PURPOSE OF REVIEW: As ventricular assist device (VAD) therapy in patients with advanced heart failure continues to grow, experience with concomitant valvular diseases present either before or after VAD implantation continues to accrue. In this review, we discuss recent data and current practice as it pertains to the subject of concomitant valvular disease in patients requiring VADs. RECENT FINDINGS: Persistent aortic valve closure has been identified as a potential contributor to aortic valve 'disuse atrophy' resulting in valve degeneration...

PURPOSE OF REVIEW: Despite the proven superiority of mitral repair over replacement for degenerative mitral disease, mitral valve replacement remains common. Guidelines now recommend referral of patients, particularly those whom are asymptomatic, to valve centers of excellence, although criteria that define such centers remain to be established. The purpose of this review is to define the structure of a mitral center of excellence and to review current clinical outcomes which are possible in such a center...
