OBJECTIVES: To investigate short- and long-term outcomes of a conservative decalcification approach in mitral valve replacement (MVR) surgery in the presence of mitral annulus calcification (MAC). METHODS: Of the 1038 patients who underwent MVR, 133 (13%) had significant MAC with at least 30% of the annular circumference heavily calcified. In most patients, the surgical approach to MAC included conservative decalcification, supra-annular prosthesis implantation and insertion of a pericardial patch between the MV annulus and the prosthesis...

BACKGROUND: Following publication of the results of the PARTNER trial, the American College of Cardiology/American Heart Association recognized the success of transcatheter aortic valve replacement (TAVR) by incorporating it as a feasible option in high-surgical risk patients, and recommending it as the standard of care for patients at prohibitive risk of surgery. Although this was recognized as a major success in the field of percutaneous valve replacement, surgical aortic valve replacement (SAVR) continued to be realized as the procedure of choice for low and intermediate surgical risk patients...

Chronic aortic regurgitation can result from various congenital and acquired anomalies and can be associated with proximal aortic disease. As the number of aortic valve procedures is growing, the incidence of post-procedural regurgitation also increases with associated morbidity. Typical evolution is characterized by a clinically silent phase of variable duration followed by a rather rapid decline with high incidence of adverse events. A challenge remains to find the optimal timing for an intervention: Patients are exposed to unnecessary surgical risks if treated prematurely, but peri- and post-operative prognosis is worse when the intervention is performed too late...

Significant periprosthetic aortic regurgitation after transcatheter aortic valve implantation has become a major concern of this technique given its association with impaired survival. We report the successful closure of such defect using a vascular occlusion device with the creation of an arterio-arterial loop to gain enough support to advance the delivery sheath into de the left ventricle.

Background Transcatheter valve-in-ring strategies have been developed to treat recurrent mitral regurgitation (MR) after failing surgical annuloplasty. However, suboptimal THV expansion with consecutive paravalvular leakage (PVL) is a procedure-immanent issue. Methods A rigid, saddle-shaped ring was cut at four locations. The segments were reconnected with pull-springs, rearranged to the original shape, and covered with a sewing cuff. The length of the annuloplasty ring construct, including extended pull-springs, was defined by the perimeter of an appropriate THV...

OBJECTIVES: To describe the feasibility and safety of the Hopscotch Technique, a novel method to close paravalvular leaks. BACKGROUND: Successful closure of paravalvular leaks requires the complete seal of irregular defects, frequently interrupted by remaining sutures or tissue that converts a large defect into a complex series of contiguous smaller defects. Successful treatment with devices placed in a single space is impossible with constrained appearance and significant residual leak; therefore, new techniques to deploy smaller devices in the correct location are needed...

Valve-in-valve implantation is generally successful in reducing paravalvular regurgitation (PVR) in cases in which the first transcatheter heart valve is deployed in a suboptimal location. We describe a case of severe PVR 2 months after implantation of a 26-mm Sapien XT valve (Edwards Lifesciences Inc, Irvine, CA) in the optimal location. Valve-in-valve implantation of a Sapien 3 valve (Edwards Lifesciences Inc), and enough left ventricular outflow tract tissue at the inflow edge the Sapien XT to appose the sealing cuff of the Sapien 3 combined for successful PVR treatment...

Transcatheter aortic valve implantation (TAVI) is the treatment of choice for inoperable and high-risk patients with severe aortic stenosis. Our objectives were to elucidate potential differences in clinical outcomes and safety between balloon-expandable versus self-expandable transcatheter heart valves (THV). We performed a retrospective cohort study of all transfemoral TAVI procedures in Ontario, Canada, from 2007 to 2013. Patients were categorized into either balloon-expandable or self-expandable THV groups...

Hybrid transcatheter Mitral Valve-in-Ring and Mitral Valve-in-Valve procedures can be an alternative to traditional surgical valve replacement in patients with high surgical risk. We present a case of a 65-year-old male with recurrent severe mitral regurgitation (MR) that failed two traditional surgical attempts due to severe chest fibrosis. We performed a mitral valve-in ring replacement with a Sapien valve followed by a mitral valve-in-valve replacement with a Melody valve. Patient had a residual paravalvular leak that was closed with a vascular plug...

OBJECTIVES: Transcatheter Aortic Valve Implantation (TAVI) can be performed via the transaxillary approach, but data about complications and procedural outcome is limited. INTRODUCTION: TAVI is an established treatment option for patients at high risk for conventional aortic valve replacement. Nowadays, the transfemoral approach is the most commonly used access for TAVI. Nevertheless, the transfemoral access is not suitable in many patients necessitating alternative approaches...
