OBJECTIVE: To determine the safety and efficacy of valve repositioning following transcatheter aortic valve replacement (TAVR) with the Lotus Valve System (Boston Scientific, Marlborough, MA, USA). INTRODUCTION: TAVR is a well-established treatment for severe aortic stenosis. The Lotus Valve System is fully repositionable and retrievable. Valve repositioning has the potential to minimize TAVR-related complications caused by valve malposition; however, the effect on adverse event rates such as stroke is unknown...

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) has been accepted as an alternative to surgery in high risk or inoperable patients with severe aortic stenosis (AS). Although transfemoral approach is the most often preferred means of access, in patients with severe ilio-femoral arteriopathy, other vascular access sites may be required. The aim of the present study was to report our experience with trans-subclavian approach for TAVR using different valve systems. METHODS: Among 273 patients undergoing TAVR between June 2011 and May 2016, 10 patients (mean age: 68...

: Transcatheter aortic valve implantation (TAVI) and balloon aortic valvuloplasty (BAV) are now well established percutaneous procedures. These procedures almost always require bursts of rapid ventricular pacing to temporarily reduce cardiac output to facilitate the procedure, usually done via a temporary pacing wire inserted into the right ventricle. We describe a case series of 132 cases of TAVI and 76 BAV done using ventricular pacing via the left ventricular lead by simply connecting one electrode to the patient's skin and one electrode through the left ventricular (LV) wire...

Transcatheter aortic valve implantation (TAVI), most commonly performed via retrograde femoral artery access, is a promising alternative to surgical aortic valve replacement in elderly, high-risk patients with severe aortic stenosis (AS). Approximately one-third of these patients suffer from severe iliofemoral arteriopathy, ruling out transfemoral approach. The case of a 74-year-old man with severe AS and bilateral iliofemoral arteriopathy treated with left trans-subclavian (TS) TAVI using the Lotus valve system is described in the present report...

BACKGROUND: Few studies have evaluated the clinical outcomes of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS). Particularly, limited data exist comparing the results of TAVR with new-generation devices versus early-generation devices. OBJECTIVES: This study sought to evaluate the clinical outcomes of TAVR for bicuspid AS with early- and new-generation devices. METHODS: The Bicuspid TAVR Registry is an international multicenter study enrolling consecutive patients with bicuspid AS undergoing TAVR between April 2005 and May 2015...

Valve embolization during transcatheter aortic valve implantation is a rare but potentially fatal complication of first generation transcatheter valves. As a result, second generation valves were designed to be fully retrievable and minimize this complication. We report a first case of embolization with a second-generation fully-retrievable and repositionable Lotus valve. In this case, the presence of severe left ventricular hypertrophy and a sigmoid septum may have contributed to prosthesis embolization with the initial 23mm Lotus valve...

A 79-year-old man with stable chronic obstructive pulmonary disease was found to have an abdominal aortic aneurysm and worsening dyspnoea. Echocardiography demonstrated critical aortic stenosis. Simultaneous endovascular aneurysm repair (EVAR) and transcatheter aortic valve replacement (TAVR) was recommended due to high surgical risk. Procedural strategy was to perform balloon valvuloplasty (BAV), followed by EVAR then TAVR. The initial 25 mm Lotus valve adopted a barrel shape suggestive of an undersized valve and was thus replaced with a 27 mm valve...

Conventional surgical aortic valve replacement is still the current "gold standard" in treatment of aortic valve disease, but part of the high-risk elder patients couldn't tolerate the surgical trauma. Now those people could receive timely and effective treatment with the application of transcatheter aortic valve replacement, and the related guidelines have been published in recent years. With its wide use in recent 10 years, different implantation systems, such as SAPIEN, CoreValve, Lotus, ACURATE neo, have been gradually improved and provened in several large clinical trials...

The advent of transcatheter aortic valve implantation (TAVI) has been rapidly evolving the treatment of the severe aortic stenosis in patients with comorbidities that lead to being high-risk for conventional aortic valve replacement. The patient selection for TAVI is carefully made by a multidisciplinary heart team. An accurate preoperative assessment of the computed tomography angiography and transesophageal echocardiography are necessary for procedural success. In Japan, SAPIEN XT and CoreValve are available, and Lotus Valve is under clinical trial...
