BACKGROUND: Feasibility of transfemoral (TF) transcathteter aortic valve replacement (TAVR) is limited by the smallest diameter, the calcification and tortuosity of the iliofemoral access vessels. The use of the Portico system without delivery sheath results in significantly lower profile delivery system compared to standard technique. We herein report our single center experience, feasibility and safety of such an approach. METHODS: The Portico valve was implanted sheathless in 81 high-risk patients with severe aortic stenosis utilizing percutaneous femoral access...

Transcatheter aortic valve replacement (TAVR) is now an accepted pathway for aortic valve replacement for patients who are at prohibitive, severe and intermediate risk for traditional aortic valve surgery. However, with this rising uptrend and adaptation of this new technology, vascular complications and their management remain an Achilles heel for percutaneous aortic valve replacement. The vascular complications are an independent predictor of mortality for patients undergoing TAVR. Early recognition of these complications and appropriate management is paramount...

von Willebrand Factor (vWF) is a well-known mediator of hemostasis and vascular inflammation. Its dynamic modulation in the bloodstream, according to hemodynamic conditions, makes it an appealing biomarker in patients with valvular heart disease (VHD). Recent studies highlight the close connection between vWF and VHD, with possible implications in the pathogenesis of VHD, promoting valve aging and calcification or favoring the development of infective endocarditis. Moreover, vWF has been recently proposed as a new diagnostic and prognostic tool in patients with valve stenosis or regurgitation, showing a strict correlation with severity of valve disease, outcome, and bleeding (Heyde syndrome)...

Severe aortic insufficiency following continuous flow left ventricular assist device (LVAD) placement requires intervention. Conventional corrective approaches are varied and morbid. Increasingly, percutaneous solutions, such as transcatheter aortic valve replacement (TAVR), have been used to rescue these patients. The unique flow characteristics in the aortic root following LVAD implantation may have unintended consequences to the TAVR leaflets. We describe the premature fusion of TAVR leaflets following 159 days of LVAD support...

Surgical valve replacement after infective endocarditis can result in local destructive paravalvular lesions. A 30-year-old woman with infective endocarditis underwent mitral valve replacement that was complicated postoperatively by 2 paravalvular leaks. During percutaneous closure of the leaks, a Gerbode defect was also found and closed. We discuss our patient's case and its relation to others in the relevant medical literature. To our knowledge, we are the first to describe the use of a percutaneous approach to close concomitant paravalvular leaks and a Gerbode defect...

Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valves has been successfully performed, but there is a lack of published experience in percutaneous treatment of patients with unicuspid valves and severe aortic stenosis. We describe a case of TAVR in such a patient. A 31-year-old woman with Turner syndrome-who had undergone coarctation repair via subclavian flap at age 7 days and an aortic valvotomy at age 6 weeks-presented with severe symptomatic aortic stenosis. She was deemed inoperable because of her severe pulmonary hypertension and numerous comorbidities; consequently, a 20-mm Edwards Sapien 3 Transcatheter Heart Valve was offered for compassionate use...

Coronary trifurcation lesions are a complex subset of lesions and are substantially more complex than bifurcations when treated with percutaneous coronary intervention (PCI) because of higher rates of acute periprocedural complications (dissection, myocardial infarction, acute vessel closure) and less effective long-term outcomes (stent thrombosis, restenosis) as compared to non-bifurcation lesions. We present the case of a 73-year-old man who was admitted to our hospital with symptomatic severe aortic stenosis who was found to have a distal left main trifurcation disease as well as porcelain aorta on work-up...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

A 64-year-old man was admitted with sudden back and chest pain. He had undergone aortic valve replacement 5 years earlier. Enhanced computed tomography showed acute type A non-communicating aortic dissection. He was initially treated with supportive medical therapy. Since he was restless, he was placed on a respirator. He went into sudden shock 6 h after onset. Percutaneous cardiopulmonary support was administered, and coronary arteriography showed progression of the dissection to the left main trunk. Percutaneous coronary intervention was performed...

Aortic valve stenosis (AS) is the most commonly operated valvular heart disease in developed countries. Aortic valve replacement is the sole effective treatment of symptomatic patients. PARTNER-1 (Placement of AoRtic TraNscathetER Valves) has recently proved the efficacy of percutaneous aortic valve replacement (TAVI : Transcatheter Aortic Valve Implantation) in patients at high surgical risk, or inoperable. In the present article, we report and discuss the results of the PARTNER-2 study in intermediate risk patients...

Mitral regurgitation is a common mitral valve dysfunction which may lead to heart failure. Because of the rapid aging of the population, conventional surgical repair and replacement of the pathological valve are often unsuitable for about half of symptomatic patients, who are judged high-risk. Transcatheter valve implantation could represent an effective solution. However, currently available aortic valve devices are inapt for the mitral position. This paper presents the design, development and hydrodynamic assessment of a novel bi-leaflet mitral valve suitable for transcatheter implantation...

Aortic valve replacement (AVR) is the treatment of choice for aortic valve disease, with excellent results reported in the short- and long-term follow-up. Due to the increasing number of patient comorbidities and older age, various technical alternatives have been developed such as transcatheter aortic valve implantation and, more recently, sutureless valve bioprostheses. For patients with very high surgical risk, transcatheter implantation is becoming the top therapeutic option. However, the percutaneous technique still has major disadvantages including those related to implantation without excision of the diseased native valve without direct view of the annulus, which increases the probability of developing perivalvular leaks and a high percentage of atrioventricular block...

BACKGROUND A free-floating ball thrombus in the left atrium is a rare clinical condition. However, the diagnosis of this condition has been facilitated by the advent and development of echocardiography and multi-detector row computed tomography (MDCT) and several cases have been reported. CASE REPORT We report a case of a 75-year-old woman who had recurrent giant spherical thrombi in the left atrium. She was diagnosed with chronic atrial fibrillation at 52 years of age. A pacemaker implantation was performed at 54 years of age because of a complete atrioventricular block; and mitral valve replacement was performed for severe mitral regurgitation at 62 years of age...
