OBJECTIVES: To determine whether ≥moderate paravalvular aortic regurgitation (PAR) after transcatheter aortic valve implantation (TAVI) independently impairs overall survival and how much the impact on survival is, we performed an updated meta-analysis pooling not unadjusted but adjusted hazard ratios (HRs). METHODS: Databases including MEDLINE and EMBASE were searched through January 2016 using PubMed and OVID. Search terms included paravalvular or perivalvular; regurgitation, leak, or leakage; percutaneous, transcatheter, transluminal, transarterial, transapical, transaortic, transcarotid, transaxillary, transsubclavian, transiliac, transfemoral, or transiliofemoral; and aortic valve...

Blunt chest trauma is a very rare cause of valve disorder. Moreover, mitral valve involvement is less frequent than is aortic or tricuspid valve involvement, and the clinical course is usually acute. In the present report, we describe the case of a 49-year-old man with a perivalvular mitral injury that became clinically manifest one year after a violent, nonpenetrating chest injury. This case is atypical in regard to the valve involved (isolated mitral damage), the injury type (perivalvular leak in the absence of subvalvular abnormalities), and the clinical course (interval of one year between trauma and symptoms)...

Mycotic cerebral aneurysms can present unique neurosurgical challenges. We report a patient with left carotid occlusions, a ruptured left middle cerebral artery mycotic aneurysm, and a rapidly appearing unruptured left anterior cerebral artery/anterior communicating artery (ACA/ACom) mycotic aneurysm in the setting of mitral valve endocarditis with a perivalvular leak and evolving congestive heart failure. Following medical stabilization and antibiotic administration, a combined endovascular (with contralateral access via the ACom) and open surgical approach was used to selectively secure both aneurysms with preservation of distal flow, allowing lifesaving cardiac valve replacement...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is currently offered to patients who are high-risk candidates for conventional surgical aortic valve replacement. For the past 37 years, off-pump aortic valve bypass (AVB) has been used in elderly patients at our center for this similarly high-risk group. Although TAVR and AVB were offered to similar patients at our center, comparisons of clinical outcomes and hospital economics for each strategy were not reported. METHODS: We reviewed the clinical and financial records of 53 consecutive AVB procedures performed since 2008 with the records of 51 consecutive TAVR procedures performed since 2012...

Paravalvular leaks (PVLs) are a well-recognized complication of prosthetic valve replacement. Perivalvular prosthetic regurgitation causes significant morbidity and is associated with high perioperative mortality if open surgical repair is required. PVLs manifest with symptoms of congestive heart failure, hemolysis, or in most cases, the combination of both. In recent years, the development of imaging and device techniques significantly shortened the duration of fluoroscopy and procedure success was achieved...

PURPOSE: We describe our initial experience with on-bypass and off-bypass (off-pump) mitral valve replacement with the modified version of our novel catheter-based sutureless mitral valve (SMV) technology, which was developed to atraumatically anchor and seal in the mitral position. DESCRIPTION: The SMV is a self-expanding device consisting of a custom designed nitinol framework and a pericardial leaflet valve mechanism. For the current studies, our original device was modified (SMV2) to reduce the delivery profile and to allow for controlled deployment while still maintaining the key principles necessary for atraumatic anchoring and sealing in the mitral valve position...

There is considerable interest in percutaneous closure of perivalvular leaks without the need for repeat surgery. Successful percutaneous closure of these defects requires extensive planning and coordination before and during the procedure. However, there is no standardized description of valve pathology in the presence of a prosthetic valve, which adds to the challenge of communication. Transesophageal echocardiography is ideally suited to guide percutaneous mitral valve procedures, because of the proximity of the mitral valve to the esophagus...

We present the case of a previously well seventy-four year old male caucasian grazier who presented with mild back pain and was subsequently found to have a large posterior mitral valve leaflet perivalvular abscess associated with mitral annulus calcification and a mycotic infrarenal abdominal aortic aneurysm (AAA) of Staphylococcal origin. He underwent a right axillofemoral bypass with oversewn aorta and a right to left femoral crossover graft, and a subsequent mitral valve repair with decalcification/debridement of the annulus and extensive posterior leaflet reconstruction with pericardium patch...

INTRODUCTION: Surgical ablation of atrial fibrillation is currently a simple procedure that can be done during cardiac surgery in most patients. A number of different energy sources now available allow to easily create ablation lines in the atria. We describe our experience during the previous three years. PATIENTS AND METHOD: In 93 patients with cardiac problems treated with surgery and permanent atrial fibrillation (longer than 3 months), surgical ablation of the arrhythmia was done at the same time...

Reoperation of patients with perivalvular leaks due to heart failure or hemolysis is associated with increased morbidity and mortality. Percutaneous closure using an Amplatzer device offers a promising alternative. We describe our initial experience between 2004 and 2006, during which we used an Amplatzer device in 8 patients for the percutaneous closure of perivalvular leaks (4 aortic and 4 mitral). The patients were all symptomatic and had a high surgical risk. Device placement was successful in all patients with mitral leaks and in 3 with aortic leaks...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has proven to be a valuable alternative to conventional surgical aortic valve replacement in high risk and surgically in operable patients who suffer from severe symptomatic aortic stenosis. However, a significant number of complications, associated with both the learning curve and device specificity, have required attention and subsequent improvement. The Symetis transapical TAVR system is a self-positioning bioprosthesis composed of a non-coronary leaflet of surgical quality porcine tissue valve sewn into a self-expanding nitinol stent that iscovered with a PET-skirt...

In patients with symptomatic severe aortic stenosis, surgical aortic valve replacement (SAVR) improves survival, quality of life, and functional status compared with medical therapy. Based on the results of the randomized PARTNER Trial, Transcatheter Aortic Valve Replacement (TAVR) using the Edwards Sapien balloon expandable valve is now available in the United States for patients who are either inoperable due to anatomic concerns or severe medical co-morbidities, or as an alternative in patients considered high risk for SAVR...

Percutaneous closure of paravalvular leaks has grown into becoming a widely considered option for treatment of hemodynamically significant regurgitation in patients with valve prosthesis. Guidance provided by the use of cardiovascular imaging techniques before and during the intervention has proved its relevance to improve accuracy and, with it, the outcome of the procedure. It has also been essential in the successful evolution of the technique and the development of devices specifically designed for it. The present work reviews the role of imaging before, during and after treatment of perivalvular prosthetic leaks and the most recent and significant advances in it...

Redo cardiac surgery represents a clinical challenge due to a higher rate of peri-operative morbidity and mortality. Mitral valve re-operations can be particularly demanding in patients with patent coronary artery bypass grafts, previous aortic valve replacement, calcified aorta or complications following a previous operation (abscesses, perivalvular leaks, or thrombosis). Risk of graft injuries, hemorrhage, the presence of dense adhesions and complex valve exposure can make redo valve operations challenging through a median sternotomy...

Late left ventricular pseudoaneurysm is a rare complication after mitral valve replacement. Most investigators have recommended surgical repair to treat left ventricular pseudoaneurysm, since untreated left ventricular pseudoaneurysm have a high risk of rupture. Here, we report a case of a 57-year old man with left ventricular pseudoaneurysm. He had two prior mitral valve replacements 16 and 19 years ago, as well as mitral and aortic valve endocarditis causing mitral valve perivalvular leak and perforation of the aortic valve...

Percutaneous paravalvular leak closure represents a small but important niche in structural interventions in the current era of interventional cardiology. It is estimated that paravalvular regurgitation affects 5-17 % of all surgically implanted prosthetic heart valves (which equates to 500 to 10,200 cases annually). Patients may present with clinical signs and evidence of heart failure, hemolysis or both. Due to the increased morbidity and mortality, reoperation is often best avoided, especially if the underlying perivalvular tissue is friable or heavily calcified...
