A 68 year-old man with a severe ischemic cardiomyopathy underwent left ventricular assist device (LVAD) implantation (Heart Mate II device) for destination therapy. He presented 49 months following LVAD implant with worsening heart failure symptoms and new severe aortic regurgitation. Given high risk for both surgical and transcatheter aortic valve replacement, he was admitted for transcatheter closure of the aortic valve under transesophageal echocardiographic (TEE) guidance. TEE imaging revealed severe aortic regurgitation (see Figure 1A and 1B, and multimedia files 1 and 2)...

Aims: Transcatheter aortic valve implantation (TAVI) is frequently associated with cardiac conduction defects (CCD) requiring permanent pacemaker implantation (PPI). Although new-onset left bundle branch block (LBBB) is often seen, the rate of progression to severe CCD is unclear. We aimed to find clinical and electrocardiographic (ECG) parameters associated with severe CCD requiring PPI in patients with a new-onset LBBB after TAVI and assess its effect on clinical outcome. Methods and results: All consecutive patients undergoing TAVI who developed a new-onset LBBB were retrospectively analysed...

Background -Current surgical and medical treatment options for severe tricuspid regurgitation (TR) are limited and additional interventional approaches are required. In the present observational study, the safety and feasibility of transcatheter repair of chronic severe TR with the MitraClip system were evaluated. In addition, the effects on clinical symptoms were assessed. Methods -Patients with heart failure symptoms and severe TR on optimal medical treatment were treated with the MitraClip system. Safety, defined as periprocedural adverse events such as death, myocardial infarction, stroke, or cardiac tamponade, and feasibility, defined as successful implantation of one or more MitraClip devices and reduction of TR by at least one grade, were evaluated before discharge and after 30 days...

Redo aortic valve replacement (AVR) performed simultaneously with left ventricular assist device (LVAD) implantation carries potential for increased mortality rates. Although transcatheter AVR has been used for patients with previous LVAD placement, no literature reports concomitant valve-in-valve transcatheter AVR and LVAD implantation. Our patient had severe aortic prosthetic valve deterioration and advanced heart failure. Given the risks associated with reoperative aortic valve surgery, we chose transcatheter AVR at the time of LVAD implantation...

Cardiovascular disease encompasses coronary artery disease and valvular heart disease, and the prevalence of both increases with age. Over the past decade, the landscape of interventional cardiology has evolved to encompass a new set of percutaneous procedures outside the coronary tree, including transcatheter aortic valve implantation, transcatheter mitral valve repair, and left atrial appendage occlusion. These interventions have sparked a new discipline within interventional cardiology referred to as structural heart disease (SHD) intervention...

Apicoaortic conduit surgery is an option for treating severe aortic stenosis. The implanted conduit valve may eventually fail and require replacement; this is usually performed by repeat surgery. Treating the conduit valve with a standard transcatheter heart valve is an option that has become feasible in recent years. We describe a case of a failed 23 mm CE bioprosthesis that was successfully treated with a 23 mm Sapien XT valve as a valve-in-valve procedure. © 2017 Wiley Periodicals, Inc.

Transaortic approach represents an alternative variant of transcatheter aortic valve implantation (TAVI) which combines benefits of antegrade transapical approach and high safety profile characteristic of transfemoral approach. This method has substantial advantages over subclavian and transapical approaches in cases of pronounced myocardial hypertrophy, left ventricular dysfunction, thinning of left ventricular wall. We describe here a hybrid intervention with simultaneous coronary artery bypass grafting and TAVI in a patient from high surgical risk group with multivessel coronary artery involvement and critical aortic stenosis...

We describe a case of very late transcatheter heart valve (THV) thrombosis of a first-generation SAPIEN prosthesis (Edwards Lifesciences, Irvine, CA) implanted in a 64-year-old woman with severe symptomatic aortic stenosis. More than 54 mo after implantation, she presented with severe symptomatic prosthesis dysfunction (stenosis) which was successfully treated with oral anticoagulation. To our knowledge, this is the tardiest case of THV thrombosis ever reported. This case should increase clinical awareness for THV thrombosis even beyond the first two-year period following implantation...
