Despite the increasing use of percutaenous valves, little is known about valve performance after external chest compression. We report a case of a compressed pulmonary Edwards Sapien® XT valve after resuscitation. With the patient on ECMO, successful redilatation was performed with unimpaired postprocedural valve function. We aim to increase the awareness for valve distortion after external chest compression with increasing numbers of transcatheter valvulations. We suggest that immediate re-evaluation of the implanted device via biplane fluoroscopy is mandatory after resuscitation in such cases...

Although nonstructural dysfunction of a bioprosthesis caused by pannus formation or native valve attachment has been well described, structural valve deterioration( SVD) caused by calcification or tear of a bioprosthesis, especially a bovine pericardial valve, is very rare in the tricuspid position. We report a case of redo tricuspid valve surgery for SVD 14 years after tricuspid valve replacement( TVR) using a Carpentier-Edwards Perimount (CEP) pericardial valve. A 71-year-old woman was referred to our hospital because of exertional dyspnea and pre-syncope...

Annuloplasty ring repair is a common procedure for the correction of mitral valve regurgitation. Commercially available rings vary in dimensions and material properties. Annuloplasty ring suture dehiscence from the native annulus is a catastrophic yet poorly understood phenomenon that has been reported across ring types. Recognizing that sutures typically dehisce from the structurally weaker posterior annulus, our group is conducting a multi-part study in search of ring design parameters that influence forces acting on posterior annular sutures in the beating heart...

BACKGROUND:  Transcatheter heart valve (THV) as valve-in-ring is increasingly used in the mitral position. Semi-rigid rings may serve as a more appropriate scaffold for proper anchoring of a THV as they may change from their oval to a round shape thereby fitting to the implanted THV. METHODS:  One rigid and five semi-rigid rings of four manufacturers, Edwards Physio I and II, Sorin 3D Memo, Medtronic Simulus, and St. Jude Medical (SJM) Saddle and SJM Sequin, with sizes 28 to 36 mm and Edwards Sapien III THV 23, 26, and 29 mm were used...

OBJECTIVES: Temporally quantify and localize paravalvular aortic leak (PVL) after transcatheter aortic valve replacement (TAVR) in the Medtronic CoreValve (MCV) versus the Edwards Sapien Valve (ESV). BACKGROUND: In order to increase the precision of THV selection and PVL intervention, an understanding of PVL characteristics is essential. METHODS: The frequency, severity, and location of post-TAVR PVL were evaluated with transthoracic echocardiography pre-discharge, one month, and one-year post-procedure in 202 patients receiving a MCV (N = 120) or ESV (N = 81)...

BACKGROUND: Expandable, rapid deployment aortic valves may interfere with the cardiac conduction system, which can lead to permanent pacemaker implantation (PPI). We sought to characterize PPI following rapid deployment aortic valve replacement (RDAVR) with the EDWARDS INTUITY valve system and investigate associated factors. METHODS: We analyzed 708 patients from 29 centers in the TRANSFORM trial undergoing RDAVR ± CABG without pre-existing pacemakers. Intrinsic conduction status was recorded as well as PPI incidence through one year...

We report a case of ascending aortic aneurysm repair and redo aortic valve replacement with a bioprosthesis 44 years after aortic valve replacement with a Starr-Edwards metal caged-ball prosthesis. The patient presented with a moderately stenotic caged-ball valve and a 50-mm ascending aortic aneurysm on a routine follow-up transthoracic echocardiography. We replaced the valve with a bioprosthesis at the time of aortic repair as the patient wished to stop anticoagulation therapy. Intraoperatively, we found that the cloth covering of the cage was nearly completely destroyed...

Aims: To correlate dynamics in electrical conduction after transcatheter aortic valve implantation (TAVI) with need for permanent pacemaker implantation (PPM) and assess implications for early discharge. Methods and results: Daily electrocardiograms after TAVI were analysed for rhythm and conduction times and were correlated with PPM. Transcatheter aortic valve implantation was performed in 291 consecutive patients with three contemporary transcatheter heart valve designs: Medtronic CoreValve (n = 111), Edwards Sapien XT (n = 29) and Sapien 3 (n = 72), and Boston Lotus (n = 79)...

Secondary mitral regurgitation (MR) results from left ventricular dilatation and dysfunction. Quantification of secondary MR is challenging because of the underlying myocardial disease. Clinical and echocardiographic evaluation requires a multi-parametric approach. Severe secondary MR occurs in up to one-fourth of patients with heart failure with reduced ejection fraction, which is associated with a mortality rate of 40% to 50% in 3 years. Percutaneous edge-to-edge mitral valve repair (MitraClip) has emerged as an alternative to surgical valve repair to improve symptoms, functional capacity, heart failure hospitalizations, and cardiac haemodynamics...

Post-surgical empyema with bronchopleural fistula can be difficult to manage. We present a case of post-operative empyema with bronchopleural fistula that was successfully treated non-operatively by placing an intrabronchial valve to address the bronchopleural fistula, which allowed for safe administration of intrapleural fibrinolytics and antibiotics for definite treatment of the empyema. While the presence of a bronchopleural fistula is considered a contraindication to the administration of intrapleural tissue plasminogen activator and deoxyribonuclease, this case demonstrates a novel use of the intrabronchial valve that could allow these medications to be used...

High pressure hydrogen gas is known to adversely affect metallic components of compressors, valves, hoses, and actuators. However, relatively little is known about the effects of high pressure hydrogen on the polymer sealing and barrier materials also found within these components. More study is required in order to determine the compatibility of common polymer materials found in the components of the hydrogen fuel delivery infrastructure with high pressure hydrogen. As a result, it is important to consider the changes in physical properties such as friction and wear in situ while the polymer is exposed to high pressure hydrogen...

BACKGROUND: Patients with atrioventricular septal defect (AVSD) may require pulmonary artery banding (PAB), either as a part of a staged uni-ventricular palliation or to allow delayed bi-ventricular repair in those presenting with early heart failure. The long-term outcomes of PAB in children with AVSD have not been previously reported. METHODS: All children with AVSD who underwent PAB at a single institution were included in the study. Data were obtained from medical records and correspondence with general practitioners and cardiologists...

Transcatheter aortic valve replacement in the setting of failed surgical bioprosthesis (valve-in-valve) is a valuable option for patients with bioprosthetic aortic stenosis or regurgitation who are deemed high risk for repeat open heart surgery. Although the procedure is successful with proper preprocedural assessment, instances of left main (LM) coronary artery ostium obstruction have been documented. We present a case of LM coronary obstruction in the immediate postoperative period following implantation of a 20-mm Edwards Sapien 3 valve inside the degenerated 21-mm Mitroflow bioprosthesis stenosis, which was treated with double stenting alongside the Edwards Sapien 3 valve creating a channel ("neo left main") that extended from mid-LM to the upper margin of the Edwards Sapien 3 valve...

BACKGROUND: Eccentric valve deployment after transcatheter aortic valve replacement (TAVR) has been associated with abnormal leaflet shear stresses that may accelerate structural valve deterioration (SVD). This phenomenon has not been studied in patients receiving Sapien 3 prostheses (Edwards Lifesciences). METHODS: A retrospective cohort analysis of 100 patients who received Sapien 3 valves between 2013 and 2015 at a single institution was performed. Axial fluoroscopic images from the co-planar view were used to assess TAVR asymmetry, which was defined as a ratio of left-to-right valve heights ≤0...
