BACKGROUND: The optimal interval between serial cardiac magnetic resonance imaging (CMRI) scans for monitoring right ventricular (RV) enlargement in the setting of severe pulmonic valve regurgitation (PR) is unknown. The purposes of this study were to (1) determine the annual change in RV volume on serial CMRI scans and (2) identify the risk factors for rapid progression of RV enlargement. METHODS: A retrospective study of adults with postintervention native valve PR and ≥2 CMRI scans at Mayo Clinic Rochester from 2000 to 2015 was conducted...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a less invasive treatment modality for patients with severe aortic valve stenosis (AS) who are at a higher risk if they have surgery. Preoperative chronic kidney disease (CKD) influences outcomes of cardiac surgery and is associated with a higher mortality and more complicated hospital course. The aims of our study were to evaluate the comparative outcomes of TAVI versus surgical aortic valve replacement (SAVR) in geriatric patients with preoperative CKD...

Insulin pumps allow patients to attain better blood glucose control with more lifestyle flexibility. Their size and cost, however, limit their usefulness. Current CSII pumps are bulky, intrusive, and expensive. SFC Fluidics is addressing these problems by developing a new type of wearable patch pump based on the patented electro-chemiosmotic (ECO) microfluidic pumping technology. This nonmechanical pumping technology allows accurate and precise delivery of very small amounts of insulin and/or other drugs, including concentrated insulin...

Mitral regurgitation (MR) is the most prevalent valvular heart disease (VHD) and represents an important cause of heart failure. Medical therapy has a limited role in improving symptoms and does not hinder the progression of valvular disease. Surgery is the treatment of choice for severe symptomatic MR; valve repair is currently the preferred surgical approach because it reduces peri-operative mortality and ensures a good medium- to long-term survival outcome. Nevertheless, a non-negligible proportion of patients with indications for surgical correction are considered to be at prohibitive perioperative risk, mainly because of old age and multiple comorbidities...

BACKGROUND: We aimed to describe the variations of extrathoracic subclavian-axillary vein location and its morphology over the first rib by venography in order to facilitate venous puncture using fluoroscopic landmarks without contrast venography, and evaluate the success rate of punctures, which made with our method. METHODS: Patients who had undergone de novo lead implantation with help of pre-puncture venography between 2011 and 2015 were enrolled. For detection of the segmental location of the axillary vein, the zones were defined (Zone 1: Posterior, Zone 2:Lateral, Zone 3:Medial) at the first rib by fluoroscopy...

OBJECTIVES: Survival in liver transplant after end-stage liver disease is associated with major cardiac functions. In a significant number of patients with end-stage liver disease, cardiac dysfunctions may be observed, which can include high-output heart failure, cardiac valve disease, and pulmonary venous and arterial hypertension. All of these affect perioperative survival. The aim of our study was to determine whether preoperative and postoperative echocardiographic parameters, specifically right heart-related tricuspid regurgitation, estimated systolic pulmonary arterial pressure, and tricuspid annular plane systolic excursion, are associated with rejection and mortality in liver transplant patients...

BACKGROUND: Results of a previous study revealed an over-ordering of blood products for cardiac surgery and led to the creation of a new blood ordering algorithm. This follow-up study has been conducted to evaluate improvement in ordering practices. METHODS: Retrospective data were collected for 171 patients who underwent coronary artery bypass grafting or valve surgery from March 2015 to March 2016 to determine the crossmatch-to-transfusion ratio (C:tx) and potential cost savings...

The non-vitamin K antagonist oral anticoagulants (NOACs), which include dabigatran, apixaban, edoxaban and rivaroxaban, are preferred over vitamin K antagonists for stoke prevention in most patients with non-valvular atrial fibrillation. The NOACs are contraindicated in atrial fibrillation patients with rheumatic mitral stenosis or mechanical heart valves. There is evidence that bioprosthetic heart valves are less thrombogenic than mechanical heart valves, but it is unknown whether the risk of thromboembolism in atrial fibrillation patients with bioprosthetic valves differs from that in patients without such valves...

Since the inception of transcatheter aortic valve replacement (TAVR), there have been significant reductions in complications due to improvements of transcatheter heart valve (THV) designs and technologies. Given expanding TAVR applications, reducing complications further and better understanding THV durability has become a focus within the structural heart space. Recently, dedicated cardiac computed tomographic angiography (CTA) performed at 1 month post-TAVR has identified subclinical leaflet thrombosis (SLT), with rates as high as 40%...

OBJECTIVES: Bioprostheses with pericardial leaflets mounted externally on the stent pose a high risk for valve-in-valve (ViV) procedures. This study analyzed the efficacy and safety of ViV procedures for treating structural valve deterioration (SVD) in Mitroflow bioprostheses. METHODS: Between January 2012 and August 2017, 11 patients (mean age 80.3 ± 5.6 years) were treated for SVD of Mitroflow bioprostheses with transcatheter ViV procedures (six transapical [TA] and five transfemoral [TF]) using balloon expandable bioprostheses...

Total aortic arch replacement using the frozen elephant trunk (FET) procedure has widely spread all over the world with more sophisticated devices. However, spinal cord injury is one of the most important complications, which limits the use of FET. In our hospital, 80 patients treated with FET had no spinal cord injury. There are three key points to avoid spinal cord injury, (1) The distal end of stent graft should be positioned up to the eighth thoracic vertebrae level; (2) the time for selective left subclavian artery perfusion and distal body circulatory arrest should be shortened within 60 min; and (3) mean blood pressure should be maintained above 70 mmHg...

Protein-losing enteropathy (PLE) is a life-threatening complication in patients following the Fontan operation. However, PLE also develops in some patients with congenital heart disease (CHD) after biventricular repair (BVR). This study compared clinical profiles of PLE patients following the Fontan operation with those after BVR. We retrospectively reviewed clinical charts of postoperative CHD patients with PLE. The study population comprised 42 PLE patients (14BVR, 28Fontan). Postoperative follow-up period until onset was significantly shorter in the Fontan group than in the BVR group (14 ± 2 vs...

This paper reports on the parameters that determine the haemocompatibility of elastomeric microvalves for blood handling in microfluidic systems. Using a comprehensive investigation of blood function, we describe a hierarchy of haemocompatibility as a function of microvalve geometry and identify a "normally-closed" v-gate pneumatic microvalve design that minimally affects blood plasma fibrinogen and von Willebrand factor composition, minimises effects on erythrocyte structure and function, and limits effects on platelet activation and aggregation, while facilitating rapid switching control for blood sample delivery...

BACKGROUND: Cardiological societies recommend, in their guidelines, that patients with atrial fibrillation and an intermediate (or higher) risk of stroke and systemic embolization should be treated with oral anticoagulant drugs. For patients who do not have mitral valve stenosis or a mechanical valve prosthesis, non-vitamin-K dependent oral anticoagulants (NOAC) are preferred over vitamin K antagonists (VKA) for this purpose. It is unclear, however, whether patients with chronic kidney disease and atrial fibrillation benefit from oral anticoagulation to the same extent as those with normal kidney function...

Despite major advancements since its first description in the 19th century, infective endocarditis remains a significant medical challenge. Although commonly involving a single valve, multiple valve involvement may occur, complicating matters even further. Triple-valve endocarditis is a very rare phenomenon. Poorly studied and described only a handful of times in the literature, little is known about the optimal therapeutic and management options in dealing with this complex entity. In this paper we describe the case of a 48-year-old male who was diagnosed with triple-valve endocarditis and provide a review of the literature to delineate what is already known and improve our understanding of this rare phenomenon...
