Aortic valve stenosis is one of the most common valvular heart disorders and the prevalence will rise as the population ages. Once symptomatic, patients with aortic valve stenosis tend to fare worse with high mortality rates. Aortic valve replacement is indicated in these patients and besides the standard surgical replacement; a less invasive approach, transcatheter aortic valve implantation, has gained momentum and has showed promising and solid results in patients with high surgical risk. An important aspect of evaluating patients with aortic valve stenosis is the ability to choose the best possible candidate for the procedure...

Here, we report concomitant resection of the left atrial appendage through the transverse sinus during minimally invasive aortic valve replacement via right anterolateral thoracotomy. The left atrial appendage was exposed by raising the collapsed ascending aorta and was safely resected using a surgical stapling device. This procedure is a feasible option in elderly patients, for whom a percutaneous procedure would be inappropriate, and could be useful for preventing thromboembolic and hemorrhagic complications...

Infective endocarditis (IE) may be accompanied by the production of a broad spectrum of autoantibodies, including antineutrophil cytoplasmic antibodies (ANCA). ANCA detection creates difficulties in the differential diagnosis of IE, especially in relation to kidney injury, the determination of the mechanism of which is important for choosing a treatment policy and estimating a prognosis. The paper describes a clinical case of a 57-year-old man who was found to have higher proteinase-3 (PR-3) ANCA titers along with the symptoms of anemia, purpura, and kidney injury during his hospitalization; echocardiography revealed vegetation on the aortic valve...

The search for an optimal aortic valve implant with durability, calcification resistance, excellent haemodynamic parameters and ability to withstand mechanical loading is yet to be met. Thus, there has been struggled to fabricate bio-prosthetics heart valve using bioengineering. The consequential product must be resilient with suitable mechanical features, biocompatible and possess the capacity to grow. Defective heart valves replacement by surgery is now common, this improves the value and survival of life for a lot of patients...

BACKGROUND: Double valve surgery is associated with an increased peri-operative morbidity and mortality. A less invasive right thoracotomy approach may be a viable alternative to median sternotomy surgery in these higher-risk patients. METHODS: We retrospectively analyzed the baseline demographics, operative characteristics, and post-operative outcomes of patients who underwent minimally invasive double valve surgery between January 2009 and December 2011 at our institution...

Minimally invasive aortic valve replacement (AVR) aims to preserve the sternal integrity and improve postoperative outcomes. In low risk patients, this technique can be achieved with comparable mortality to the conventional approach and there is evidence of possible reduction in intensive care and hospital length of stay, transfusion requirement, renal dysfunction, improved respiratory function and increased patient satisfaction. In this review, we aim to asses if these benefits can be transferred to the high risk patient groups...

BACKGROUND: Bicuspid aortic valve (BAV) aortopathy is well known in literature even if only few data exist regarding isolated supra-coronary aneurysm with normally functioning valve and root. Aim of this study is to clarify the long-term fate of bicuspid aortic root spared at the time of ascending aorta surgery. METHODS: We identified forty-seven patients (mean age, 57±11 y; range, 35-81 y, 31 males) who were treated by means of supracoronary aortic replacement in presence of normally functioning BAV and not significantly enlarged sinues of Valsalva...

This is a case of a 54-year-old female with a history of mechanical aortic valve replacement who presented in cardiogenic shock. Her primary care provider started her on rivaroxaban for anticoagulation therapy. An urgent transesophageal echocardiogram revealed a significant gradient and thrombosis on one leaflet of the valve that was immobile. Given that she was not a surgical candidate, she underwent thrombolysis. However, she later died due to complications from the thrombotic valve. The utility of target-specific oral anticoagulants has yet to be established in clinical practice...

BACKGROUND: The use of transcatheter aortic valve replacement (TAVR) is increasing worldwide. We present our 6-year experience using three-dimensional (3D) transesophageal echocardiography (TEE) and investigate whether different sizing methods of the aortic annulus lead to different prosthesis size that may impact outcome. METHODS: We investigated 262 patients who underwent TAVR and had 3D TEE data sets of the aortic annulus. We have used the area-derived diameter (Darea = 2(area/π)) and the circumference-derived diameter (Dcirc = Circumference/π) to size the prosthesis in separate populations in different time periods...

BACKGROUND: The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures. Among these concomitant anomalies, simultaneous association of both a single coronary ostium and aneurysmal ascending aortic dilation in combination with the quadricupsid aortic valve has not been reported yet. CASE PRESENTATION: We experienced the case of a 56-year-old female patient presenting as aortic regurgitation resulted from malcoaptation of quadricupsid aortic valve...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is typically performed under general anesthesia (GA). However, there is increasing data supporting the safety of performing TAVR under local anesthesia/conscious sedation (LA). We performed a meta-analysis to gain better understanding of the safety and efficacy of LA versus GA in patients with severe aortic stenosis undergoing TAVR. METHODS AND RESULTS: We comprehensively searched EMBASE, PubMed, and Web of Science...
