To report on 2 rare cases of balloon-expandable transfemoral transcatheter aortic valve implantation, where a trapped balloon led to complications requiring acute intervention. Both patients were elderly with increased risk profile and had been discussed by the heart team. After standard positioning of the valves using a transfemoral approach, retrieval of the pusher before deployment of the valve was missed. In 1 patient, rapid pacing was continued, the balloon deflated, the pusher pulled back and the balloon repositioned and reinflated...

Valve-in-valve implantation is an alternative to reoperation for patients with degenerated bioprostheses. This case report presents a 75-year-old woman presenting with worsening dyspnoea according New York Heart Association (NYHA) Class III after she had received a Sorin Perceval® S sutureless valve due to severe aortic valve stenosis 5 years ago. Echocardiography revealed a degenerated Perceval valve with severe valvular aortic regurgitation and stenosis. After exclusion of acute infective endocarditis, an Edwards SAPIEN 3 was implanted leading to an immediate haemodynamic improvement...

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)...

OBJECTIVES: It may be expected that patients with left ventricular dysfunction may be at greater risk of complications after transcatheter aortic valve implantation (TAVI) via transapical (TA) access compared with via transfemoral (TF) access. There is a lack of data comparing the outcomes of TAVI using TA and TF access in patients with a reduced left ventricular ejection fraction (EF). METHODS: This is a retrospective analysis of data from a high-volume heart centre in Germany...

In 2013, we published a simple method for aortic valve reconstruction in children using fixed pericardium in this journal. This was not expected to be a durable solution but a temporizing measure in the absence of other solutions, in order to buy time for growth that would allow subsequent prosthetic valve insertion. As such, this was implemented in 3 patients with excellent immediate results, as reported in our original publication. We are now writing to provide longer term information. In 2 cases, a newborn and a 12-year-old boy, the valve calcified heavily at 4 years' follow-up...

A 15-year-old patient with hypoplastic left heart syndrome underwent 3-stage palliation by the age of 3 years. He was later diagnosed with Loeys-Dietz syndrome. On follow-up imaging, the neoaorta was dilated at 50 mm in diameter. He underwent aortic root replacement with a composite valve conduit and hemiarch replacement, using a boat-shaped Dacron graft. The uncertainty of how univentricular circulation would tolerate long bypass time steered us away from a total arch replacement. His postoperative recovery was uneventful...

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...

OBJECTIVES: In contrast to stented transcatheter aortic valves, the Direct Flow Medical (DFM) valve is a stentless bovine aortic bioprosthesis mounted in a non-metallic inflatable frame. Hence, severe asymmetric annular calcification may result in residually elevated transaortic pressure gradients after DFM implantation. We present a novel intraprocedural dilatation (IDIL) technique for successful implantation of the DFM valve in the presence of complex annular calcification. METHODS: Between January 2014 and May 2015, 55 patients underwent DFM valve-based transcatheter aortic valve implantation at our institution...

OBJECTIVES: The transapical approach provides concurrent surgical access to the mitral and the aortic valves, the root of the aorta and the left atrium. We previously showed the feasibility of transapical cardioscopic (TAC) surgery in a non-survival porcine model. However, reproducibility and feasibility of ring implantation using TAC have not been reported. Therefore, in this study, we hypothesized that implantation of a mitral annuloplasty ring can be feasibly and safely carried out endoscopically via the apex of the heart...

OBJECTIVES: Failure of mechanical conventional ventilation (MCV) after cardiac surgery portends a dismal prognosis, with extracorporeal membrane oxygenation frequently utilized as a salvage therapy. We describe our experience with high-frequency percussive ventilation (HFPV) as a rescue therapy for hypoxaemia refractory to MCV after cardiac surgery. METHODS: In a 6-year retrospective analysis from 2009 to 2015, we identified 16 subjects who required HFPV after cardiac surgery...

Quadruple-valve endocarditis is a challenging condition, for which there is limited treatment experience and poor overall survival. We report the first case caused by Abiotrophia defectiva that has been surgically treated both with the replacement of the aortic and pulmonary valves and the repair of the mitral and tricuspid valves with a good outcome. The patient's clinical course is described and a review of literature on this rare causative agent is given.

BACKGROUND: Monitoring cardiac output (CO) is important to optimize hemodynamic function in critically ill patients. The prevalence of aortic valve insufficiency (AI) is rising in the aging population. However, reliability of CO monitoring techniques in AI is unknown. The aim of this study was to investigate the impact of AI on accuracy, precision, and trending ability of transcardiopulmonary thermodilution-derived COTCPTD in comparison with pulmonary artery catheter thermodilution COPAC...

OBJECTIVES: Iliofemoral arteries have been the preferred access for transcatheter aortic valve replacement (TAVR). When these arteries are too small, calcified or tortuous, an alternative access must be considered. Transinnominate (TI) access is an extrathoracic approach that does not require manipulation of major neurovascular structures or the apex. The aim of this study is to evaluate the efficacy and safety of TI TAVR as an alternative access in patients with severe aortic stenosis not amenable to a transfemoral approach...

BACKGROUND: Mutations in LMNA gene, encoding Lamin A/C, cause a diverse array of phenotypes, collectively referred to as laminopathies. The most common manifestation is dilated cardiomyopathy (DCM), occurring in conjunction with variable skeletal muscle involvement but without involvement of the coronary arteries. Much less commonly, LMNA mutations cause progeroid syndromes, whereby an early-onset coronary artery disease (CAD) is the hallmark of the disease. We report a hitherto unreported compound cardiac phenotype, dubbed as "non-syndromic cardiac progeria", in a young patient who carried a rare pathogenic variant in the LMNA gene and developed progressive degeneration of various cardiac structures, as seen in the elderly...
