Pregnant women with stenotic degeneration of bioprosthetic cardiac valves may require another valve replacement procedure when their symptoms deteriorate with progression of pregnancy, but fetal mortality is higher with cardiac surgery done on cardiopulmonary bypass. Transcatheter valve-in-valve implantation may help to improve the fetal and maternal outcomes in these situations. Double valve-in-valve implantation is rare and has not been reported in a pregnant patient. We report, for the first time, the case of a pregnant woman with stenotic bioprosthetic valves in the mitral and aortic positions, who underwent a successful concomitant, transcatheter, double valve-in-valve implantation through the left ventricular apical route during the second trimester of her precious pregnancy...

OBJECTIVE: To assess the outcomes of transatrial implantation of a transcatheter heart valve (THV) for the treatment of mitral valve disease with severe mitral annular calcification (MAC). METHODS: Implantation of a balloon-expandable THV was performed on cardiopulmonary bypass via left atrial exposure in patients considered at risk for left ventricular outflow tract obstruction. The anterior mitral valve leaflet was systematically resected and pledgeted sutures were placed to enhance stability and reduce paravalvular leak...

Adaptation and evolution of transcatheter aortic valve replacement (TAVR) technologies has led to approval of TAVR for consideration in patients at intermediate risk for surgical aortic valve intervention. As TAVR becomes more mainstream, attention is shifting toward percutaneous mitral valve (MV) repair and transcatheter MV replacement (TMVR) techniques. Transcatheter heart valves (both purpose-built and off-label-use TAVR valves) are being implanted during TMVR procedures to treat clinically significant MV disease (native disease, degenerated bioprosthetic valves, and dysfunctional surgical MV annuloplasty repairs) when the risk of open heart MV surgery is prohibitive...

Mitral regurgitation (MR) is a valvular heart disease associated with significant morbidity and mortality. Transcatheter mitral valve intervention (TMVI) repairs or replaces the mitral valve through small arterial and venous entry sites and so avoids risks associated with open heart surgery. Transcatheter devices targeting components of the mitral apparatus are being developed to repair or replace it. Numerous challenges remain including developing more adaptable devices and correction of multiple components of the mitral annulus to attain durable results...

Valvular heart disease is a major public health issue. The prevalence of valvular heart disease is expected to increase due to an aging population. Valve dysfunction manifests as valve stenosis, regurgitation, or both, due to various etiologies. Valve repair and replacement are the main treatment options for severe valve dysfunction. Valve replacement is achieved by using either a mechanical or a bioprosthetic valve. Mechanical valves are more durable but require lifelong anticoagulation with associated complications...

We describe a hybrid surgical-interventional technique for minimally-invasive implantation of a transcatheter aortic valve in the mitral position. This technique does not require circular mitral annular calcification and minimizes the risk for left ventricular outflow tract obstruction. We believe this technique represents a useful approach for surgeons and interventional cardiologists until specialized transcatheter mitral valve devices become available.

As new transcatheter mitral valve (MV) interventions continuously evolve, potential procedure-related adverse events demand careful investigation. The risk of cerebral embolic damage is ubiquitous in any left-sided structural heart intervention (and potentially linked to long-term neurocognitive sequelae); therefore, efforts to evaluate these aspects in the field of catheter-based MV procedures are justified. Given the peculiarities of MV anatomy, MV disease, and MV procedures, the lessons learned from other transcatheter heart interventions (i...

Transcatheter mitral valve replacement with the TiaraTM valve can be performed in inoperable patients with severe functional regurgitation. Risk of left ventricular outflow tract obstruction can be prevented using preoperative 3D-imaging and 3D-printed models. However, in case of mono-disk mechanical prosthesis previously implanted in aortic position (Bjork-Shiley) there is an additional risk of mechanical interference leading to reduced leaflet motion and aortic valve dysfunction. Hereafter, we describe the case of a patient with a 27mm mono-disk mechanical aortic valve implanted in 1978, Euroscore-II of 18% and STS-score (mortality) of 16% who successfully underwent a transapical TiaraTM valve implantation...

Transapical transcatheter aortic valve implantation is a well-established alternative in patients at a high risk for conventional aortic valve replacement. We performed transapical transcatheter aortic valve implantation on an 83-year-old woman with symptomatic severe aortic stenosis. Intraoperative transoesophageal echocardiography (TOE) after transcatheter aortic valve implantation showed mild mitral regurgitation without intracardiac structural injury. In the intensive care unit, the patient gradually had haemodynamic instability; TOE revealed severe mitral regurgitation with A2 and A3 prolapse due to rupture of the posterior papillary muscle...

PURPOSE OF REVIEW: Recent advancements in transcatheter valvular interventions have resulted in a growing demand for advanced cardiac imaging to help guide these procedures. RECENT FINDINGS: Both echocardiography and multi-detector computed tomography have played essential roles in the maturation of transcatheter aortic valve replacement and are now building on these experiences and helping inform the nascent field of transcatheter mitral interventions. Advanced imaging is essential to aid in the diagnosis and determination of the mechanism of mitral regurgitation...

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...
