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)...

PURPOSE: Transcarotid transcatheter aortic valve implantation (TAVI) is one alternative approach if unfavorable femoral access. However, this approach may cause cerebral vascular accidents (CVAs) by temporarily occluding common carotid artery (CCA). The purpose of this study is to develop a new method reducing cerebral ischemia during transcarotid TAVI. METHODS: We inserted an 8- and 18-Fr. sheath in CCA with tip toward brain and aortic arch, respectively, and connected their side arms to create a bypass flow...

OBJECTIVES: Favourable outcomes with mitral annuloplasty have been achieved with transapical cardioscopic (TAC) surgery in a survival animal model. In addition, experimental TAC on a non-survival animal model also showed adequate access to remove the native mitral valve and implant a prosthetic valve, but the surgical procedure took a long time and lacked follow-up data. The goal of this study was to develop a clinically translatable TAC mitral valve replacement (MVR) procedure using technical and instrumental refinements to reduce the surgical time and to evaluate functional recovery and short-term durability using a survival porcine model...

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...

Percutaneous therapies for congenital heart disease have been evolving rapidly despite limited investment from industry. The Melody transcatheter pulmonary valve (Medtronic, Inc, Minneapolis, MN USA) replacement therapy represents an important advancement in this arena. It has been approved in the United States for use in the pulmonary position, on a Humanitarian Device Exemption status. Off-label use of the Melody transcatheter pulmonary valve has extended to the mitral, pulmonary, and aortic valves, especially in previously implanted valves with prosthetic valve degeneration...

BACKGROUND: Stented bioprosthetic valves (BPVs) are commonly used for surgical pulmonary valve (PV) replacement in postoperative congenital heart disease, but develop structural failure in a time-related fashion. The Melody transcatheter PV (TPV) (Medtronic, Minneapolis, Minn) has been used to treat BPV dysfunction, but there have been few studies in this population. METHODS: We performed a retrospective, multicenter study to evaluate Melody valve function in patients who underwent TPV replacement (TPVR) into a dysfunctional pulmonary BPV...

Trans-carotid access for trans-catheter aortic valve replacement is a valid alternative in patients with aortic valve dysfunction, severe peripheral vascular disease, and high-risk for surgery. However, in the event of the need for a bailout valve-in-valve procedure, the safety of this access site is uncertain. We report a patient with aortic regurgitation, previous coronary surgery, peripheral vascular disease, and impaired ventricular function who underwent a CoreValve Evolut-R (Medtronic Inc, Minneapolis, MN) implantation through the left carotid artery followed by a successful valve-in-valve procedure with a 26-mm Edwards Sapien3 valve (Edwards Lifesciences, Irvine, CA) through the same carotid access site...

Trancatheter heart valve (THV) thrombosis is effectively treated with anticoagulation but alternative therapies are required when a faster gradient reduction is needed. Open heart surgery has been rarely performed due to the high perioperative mortality and only five cases have been described so far. Here we describe a case of emergent surgical explantation for THV thrombosis after a valve-in-valve. A 67years old man underwent transcatheter aortic valve implantation for a failed surgical bioprosthesis Epic 21mm (St...

BACKGROUND AND AIM OF THE STUDY: Xenograft conduits have been used successfully to repair congenital heart defects, but are prone to failure over time. Hence, in order to improve patient outcomes, better xenografts are being developed. When evaluating a conduit's performance and safety it must first be compared against a clinically available control in a large animal model. The study aim was to evaluate a clinically available xenograft conduit used in right ventricular outflow tract (RVOT) reconstruction in a sheep model...

We describe three patients with severe aortic regurgitation after aortic root replacement using the Medtronic Freestyle® bioprosthesis. In two cases, the indication was endocarditis. The third case showed rupture of the right coronary cusp. To achieve fewer complications, lower operative risk and save operative and cross-clamp times, implantation of a sutureless bioprosthesis in a valve-in-valve manner was performed. In two cases, a Perceval bioprosthesis and in the other case, a 3f-Enable bioprosthesis were used...
