We report a case of delayed treatment of a partial aortic valve leaflet avulsion during transcatheter aortic valve replacement (TAVR) and its successful management by a percutaneous snare retrieval technique. Post-TAVR transesophogeal echocardiography showed an avulsed native valve leaflet. We deferred retrieval of the mass with anticoagulant agents. One month later, a 30-mm EN-Snare was used to snare the mass. This case report demonstrates that the management of an avulsed aortic valve leaflet can be safely deferred with the use of an anticoagulant agent...

Transcatheter aortic valve implantation (TAVI) has proven to be the standard of care for patients with prohibitive and high operative risk; today, it is considered a reasonable alternative to surgical aortic valve replacement in intermediate-risk patients. As indications for TAVI move toward patients at lower risk, safety aspects are becoming even more important. Furthermore, adequate patient selection is key for predictable procedural success with minimal complications, translating into an optimal clinical outcome...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been reported to be advantageous over surgical aortic valve replacement owing to the low incidence of prosthesis-patient mismatch (PPM) and large effective orifice area (EOA). However, data on TAVI for extremely small annuli are limited. The present study aimed to compare post-procedural hemodynamics and morphology between 20-mm and 23-mm Sapien XT (SXT) transcatheter heart valves (THVs) with extremely small annuli (<314mm(2))...

PURPOSE: Aortic valve area (AVA) is usually estimated by the continuity equation (CE) in which the left ventricular outflow tract (LVOT) area is calculated assuming a circular shape. This study aimed to compare measurements of LVOT area using standard 2D transthoracic echocardiography (2DTTE), 3D transesophageal echocardiography (3DTEE), and multidetector computed tomography (MDCT) and assess their relative impact on AVA estimated by the CE. METHODS AND RESULTS: We prospectively enrolled 60 patients with severe aortic stenosis (AS) referred for transcatheter aortic valve replacement (TAVR) who systematically underwent 2DTTE, 3DTEE, and MDCT...

OBJECTIVE: Mitral valve (MV) regurgitation due to degenerative MV disease is the leading cause of cardiac death in dogs. We carried out preliminary experiments to determine the feasibility and short-term effects of beating-heart MV repair using an expanded polytetrafluorethylene (ePTFE) chordal implantation device (Harpoon TSD-5) in dogs. ANIMALS: This study involved six healthy purpose-bred Beagles (weight range 8.9-11.4 kg). MATERIAL AND METHODS: Following a mini-thoracotomy performed under general anesthesia, the TSD-5 was used to place 1 or 2 artificial ePTFE cords on the anterior MV leaflet or the posterior MV leaflet via a left-ventricular transapical approach...

BACKGROUND: With improved survival of patients undergoing primary bioprosthetic aortic valve replacement (AVR), reoperation to relieve severe prosthetic aortic stenosis (PAS) is increasing. Timing of redo surgery in asymptomatic/minimally symptomatic patients remains controversial. Left ventricular (LV) global longitudinal strain (GLS) is a marker of subclinical LV dysfunction. In asymptomatic/minimally symptomatic patients with severe PAS undergoing redo AVR, we sought to determine whether LV-GLS provides incremental prognostic use...

Transcatheter valve-in-valve (VIV) implantation has been recently proposed as an alternative to surgical reoperative aortic valve replacement in patients with a failing aortic bioprosthesis. Experience with transcatheter VIV implantation at other valve positions is very limited. Herein is reported the case of an 18-year-old man with Ebstein's anomaly and severe tricuspid valve (TV) regurgitation status after bioprosthetic valve replacement, who developed new dyspnea on exertion three years after the initial valve replacement...

Arash Salemi, Berhane M Worku
Transcatheter aortic valve replacement (TAVR) has become a widely accepted therapeutic option for patients with severe, symptomatic aortic stenosis at intermediate, high, or extreme risk for conventional surgery as determined through a heart team approach. Two valve prostheses are currently available and the Food and Drug Administration (FDA) approved in the United States for TAVR: the self-expandable Medtronic CoreValve (Medtronic, Inc., Minneapolis, MN, USA) and the balloon-expandable Edwards Sapien Valve (Edwards Lifesciences, Irvine CA, USA)...

Aortic root rupture and cardiac tamponade during transcatheter aortic valve implantation is a frightening complication with high mortality rate. A conservative management of this complication could represent an initial strategy, especially in high-risk patients, to avoid emergent cardiac surgery. This conservative management includes: Immediate detection of pericardial effusion by echocardiography, a fast instauration of pericardial drainage, auto-transfusion and anticoagulation reversal. We describe two cases of patients who suffered this complication and were treated successfully with this initial approach...

Background Transcatheter aortic valve implantation has been established as a safe and effective treatment option for patients at high or prohibitive surgical risk. However, some patients may not be suitable for the transfemoral approach due to severe iliofemoral disease or aneurysmal disease of the thoracoabdominal aorta. The aim of this case series was to evaluate the feasibility and clinical outcomes of the transaortic approach. Methods From May 2015 to June 2016, 5 patients (mean age 78.4 ± 3.9 years) with severe symptomatic aortic stenosis underwent transaortic transcatheter aortic valve implantation after a heart team discussion...

Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valves has been successfully performed, but there is a lack of published experience in percutaneous treatment of patients with unicuspid valves and severe aortic stenosis. We describe a case of TAVR in such a patient. A 31-year-old woman with Turner syndrome-who had undergone coarctation repair via subclavian flap at age 7 days and an aortic valvotomy at age 6 weeks-presented with severe symptomatic aortic stenosis. She was deemed inoperable because of her severe pulmonary hypertension and numerous comorbidities; consequently, a 20-mm Edwards Sapien 3 Transcatheter Heart Valve was offered for compassionate use...
