A 40-year-old man with osteogenesis imperfecta type I submitted to multiple procedures of surgical mitral and aortic valve replacement was referred for refractory congestive heart failure due to significant paravalvular leaks (PVLs) of both mitral and aortic prostheses. Due to perceived very high risk of a further mitroaortic surgery, transcatheter closure of PVLs under three-dimensional echocardiographic guide was performed. Thus, four Amplatzer Vascular Plug type II (St. Jude Medical Corp, St. Paul, Minnesota, USA) devices were implanted into the aortic PVLs, and three Amplatzer Vascular Plug type II devices were used to occlude a huge mitral PVL...

Cardiovascular diseases continue to be a major cause of mortality and morbidity in the world population. First open heart procedure was performed by Gibbon in 1953, since then many advancements have been introduced to the field of cardiac surgery. Minimally invasive techniques were introduced, which include minimally invasive coronary artery bypass grafting (CABG), off-pump technique, minimally invasive valve surgery or transcatheter techniques to implant stentless or sutureless valves. The hybrid strategy to address coronary disease combines catheterisation procedures with standard surgical techniques...

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...

BACKGROUND: There are limited data regarding the influence of liver dysfunction on outcomes of transcatheter aortic valve implantation (TAVI). Model for End-stage Liver Disease eXcluding International normalized ratio (MELD-XI) score, which was originally developed for patients with cirrhosis awaiting liver transplantation, has been reported as a predictor of heart disease. The aim of this study was to investigate the prognostic value of MELD-XI score for patients undergoing TAVI. METHODS: Data from the prospectively maintained Optimized transCathEter vAlvular iNtervention (OCEAN-TAVI) multicenter registry were collected in 749 patients who underwent TAVI between October 2013 and August 2015...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been adopted worldwide as the standard treatment for severe aortic stenosis in symptomatic patients at prohibitive or high surgical risk, but there are still several areas where consensus and evidence are lacking. The purpose was to obtain a global view of current practice related to TAVI with the potential to identify the main areas of consensus and divergence between centers. METHODS: An online questionnaire was distributed in centers performing TAVI including a total of 59 questions concerning pre-procedural evaluation, procedural practices and post-procedural management...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

Aortic stenosis is the most frequent and mitral stenosis is the least frequent native single-sided valve disease in Europe. Patients with the combination of severe symptomatic degenerative aortic and mitral stenosis are very rare. Guidelines for the treatment of heart valve diseases are clear for single-valve situations. However, there is no common agreement or recommendation for the best treatment strategy in patients with multiple valve disease and severe concomitant comorbidities. A 76-year-old female patient with the combination of severe degenerative symptomatic aortic and mitral stenosis and several comorbidities including severe obesity, who was found unsuitable surgical candidate by the heart team and unsuitable for two-time general anesthesia in the case of two-step single-valve percutaneous approach by anesthesiologists, underwent successful percutaneous dual-valve single-intervention (transcatheter aortic valve implantation and percutaneous mitral balloon commissurotomy)...

Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus...

Although rheumatic heart disease is becoming uncommon in industrialized countries, its global burden is still significant. We report the case of a 70-year-old male with rheumatic heart disease, who underwent 4 previous heart valve replacement surgeries, and presented to our hospital with refractory heart failure (NYHA functional class IV) due to severe stenosis of a previously implanted tricuspid bioprosthesis. The Heart Team deemed the patient as inoperable/high-risk for surgery. As an alternative, a transcatheter tricuspid valve-in-valve replacement was decided upon and later executed through the right femoral vein, with the insertion of an Edwards SAPIEN XT 29 no...

Right heart failure is not uncommon in the patients with repaired tetralogy of Fallot (rTOF). Although commercialized transcatheter stent-mounted pulmonary valves are effective treatment options for improving functional class and for normalizing right ventricular volumes in such patients, they are not available in Taiwan. To provide a handmade alternative, we report our successful transcatheter attempt of a handmade assembled left pulmonary artery valved stent graft implantation in a 61-year-old man who had a history of rTOF and severe branch pulmonary regurgitation...

OBJECTIVES: The purpose of this study was to evaluate the incidence, predictors, and clinical outcomes of permanent pacemaker (PPM) implantation following transcatheter aortic valve replacement (TAVR). BACKGROUND: Conduction abnormalities leading to PPM implantation are common complications following TAVR. Whether PPM placement can be predicted or is associated with adverse outcomes is unclear. METHODS: A retrospective cohort study of patients undergoing TAVR in the United States at 229 sites between November 2011 and September 2014 was performed using the Society of Thoracic Surgeons/American College of Cardiology TVT Registry and the Centers for Medicare and Medicaid Services database...

Coronary obstruction during or after transcatheter aortic valve replacement is a rare and catastrophic sequela that occurs most frequently just after valve implantation. Even rarer is the delayed clinical presentation, in some few patients, of coronary obstruction on the day after self-expandable valve implantation. Here we describe a case of balloon-expandable (not self-expandable) transcatheter aortic valve replacement, followed by partial obstruction of the left main coronary artery on the day after that procedure in a 93-year-old man, despite normal left ventricular contraction just after valve implantation...

Management of dialysis patients with valvular heart disease waitlisted for kidney transplantation is challenging. Development of severe aortic valve stenosis can lead to the exclusion from the transplant program or even death while on the waiting list. In dialysis patients, surgical aortic valve replacement is associated with a high perioperative risk with increased morbidity and mortality. In contrast, transcatheter aortic valve implantation emerges as a viable option for dialysis patients. Herein, we present the long-term follow-up of successful kidney transplantation after TAVI in a diabetic patient receiving long-term hemodialysis...

Transcatheter valve interventions have emerged as one of the most important developments in structural heart disease over the past 20 years. Initially, these interventions were directed at patients with severe aortic stenosis and high surgical risk; however, their applications have extended to involve other native valves' pathologies, degenerated prosthetic valves, as well as patients of lower surgical risk. In this article, we discuss the importance of cardiac imaging in transcatheter aortic valve replacement (TAVR) by exploring the current practices, guidelines, and recommendations with the supporting data...

The Melody® transcatheter pulmonary valve system was developed for placement within right ventricle-to-pulmonary artery conduits in patients with CHD for treatment of stenosis or regurgitation, providing an alternative to open-heart surgery. Abnormal systemic venous connections altering the catheter course to the right ventricle-to-pulmonary artery conduit may present a challenge to Melody® valve implantation. We present two such cases, in which the Melody® valve was successfully implanted in teenage patients with congenitally corrected transposition of the great arteries after Senning atrial switch operation...

A hybrid strategy, firstly performed in the 1990s, is a combination of tools available only in the catheterization laboratory with those available only in the operating room in order to minimize surgical morbidity and face with any cardiovascular lesion. The continuous evolution of stent technology along with the adoption of minimally invasive surgical approaches, make hybrid approaches an attractive alternative to standard surgical or transcatheter techniques for any given set of cardiovascular lesions. Examples include hybrid coronary revascularization, when an open surgical anastomosis of the left internal mammary artery to the left anterior descending coronary artery is performed along with stent implantation in non-left anterior descending coronary vessels, open heart valve surgery combined with percutaneous coronary interventions to coronary lesions, hybrid aortic arch debranching combined with endovascular grafting for thoracic aortic aneurysms, hybrid endocardial and epicardial atrial fibrillation procedures, and carotid artery stenting along with coronary artery bypass grafting...
