A 53-year-old woman was referred to us for reoperation of aortic root. Twenty-three years ago, she was diagnosed with aortitis and suffered from annuloaortic ectasia, aortic regurgitation, severe stenosis of left carotid and subclavian arteries and occulusion of the main trunk of left coronary artery. The left coronary system was perfused by collateral arteries from right coronary artery. She had undergone original Bentall procedure( Cooley graft 26 mm+SJM valve 25 mm) with coronary artery bypass grafting (CABG)[saphenous vein graft (SVG)-left anterior descending artery (LAD)]...

The design and characterization of a new laser-desorption molecular beam source, tailored for use in x-ray free-electron laser and ultrashort-pulse laser imaging experiments, is presented. It consists of a single mechanical unit containing all source components, including the molecular-beam valve, the sample, and the fiber-coupled desorption laser, which is movable in five axes, as required for experiments at central facilities. Utilizing strong-field ionization, we characterize the produced molecular beam and evaluate the influence of desorption laser pulse energy, relative timing of valve opening and desorption laser, sample bar height, and which part of the molecular packet is probed on the sample properties...

OBJECTIVES: The objective is to compare the short-term (30 days) and late (12 months) vascular adverse events in patients undergoing transfemoral (TF)-transcatheter aortic valve replacement (TAVR) by surgical cut-down (SC) vs. percutaneous (PC) approaches. BACKGROUND: Programs continue to utilize both approaches in TF-TAVR. There are limited data comparing outcomes by SC vs. PC approaches and long-term effects of endovascular intervention facilitated hemostasis on late vascular adverse events...

Aims: Filamin-A (FLNA) was identified as the first gene of non-syndromic mitral valve dystrophy (FLNA-MVD). We aimed to assess the phenotype of FLNA-MVD and its impact on prognosis. Methods and results: We investigated the disease in 246 subjects (72 mutated) from four FLNA-MVD families harbouring three different FLNA mutations. Phenotype was characterized by a comprehensive echocardiography focusing on mitral valve apparatus in comparison with control relatives...

BACKGROUND: Pressure and waveform at the catheter tip are continuously monitored during catheterization of pulmonary artery to ensure accurate catheter placement. We present a case in which pulmonary venous blood was unexpectedly collected from the pulmonary artery catheter despite pulmonary artery pressure and waveform detection at the catheter tip, and describe the measures taken to correct the catheter placement. CASE PRESENTATION: A 74-year-old male underwent mitral valve plasty for cardiac failure caused by mitral valve regurgitation...

OBJECTIVE: To determine the value of ultralow-dose chest CT for estimating the calcified atherosclerotic burden of the thoracic aorta using tin-filter CT and compare its diagnostic accuracy with chest direct radiography. METHODS: A total of 106 patients from a prospective, IRB-approved single-centre study were included and underwent standard dose chest CT (1.7 ± 0.7 mSv) by clinical indication followed by ultralow-dose CT with 100 kV and spectral shaping by a tin filter (0...

The study was aimed at evaluation of the feasibility and potential benefit of image fusion (IF) of pre-procedural CT angiography (CTA) and x-ray (XR) fluoroscopy for image-guided navigation in transfemoral transcatheter aortic valve implantation (TAVI) with the strong focus on guiding the double-filter cerebral embolic protection device and valve prosthesis placement. METHODS: In 31 patients undergoing TAVI, image registration of CTA-derived 3D anatomical models of the relevant cardiac anatomy and vasculature, and live XR was performed applying a commercially available navigation tool...

BACKGROUND: Previous trials have shown that, among high-risk patients with aortic stenosis, survival rates are similar for transcatheter aortic-valve implantation (TAVI) and surgical aortic valve replacement. The study aimed to compare the outcomes of aortic valve replacement according to the adopted surgical approach in intermediate and low risk patients. METHODS: This is a retrospective, observational, cohort study of prospectively collected data from 421 patients undergoing isolated aortic valve replacement between 2011 and 2015...

OBJECTIVE: Endomyocardial fibrosis (EMF) is a rare disease and is often an underdiagnosed and forgotten cardiomyopathy. The objective of this study was to document the current frequency of EMF in Sudan by defining and selecting cases from patients attending the echocardiography laboratory. Additionally we aimed to create an EMF registry for Sudan. METHODS: The study started in January 2007 and is on-going. All the patients attending our echocardiography clinics in four different hospitals in Khartoum, Sudan, were included...

BACKGROUND: Mitral valve replacement is the procedure of choice in patients with severe mitral valve disease. However, these patients are surviving longer and are thus at an increased risk of prosthesis failure or valve-related complications. METHOD: Study setting: Inkosi Albert Luthuli Central Hospital, a tertiary referral Hospital in Durban. Study population: All patients undergoing redo mechanical mitral valve replacement surgery between January 2005 and December 2014...

A 54-year-old man presented at our facility with a 3-month history of exertional breathlessness and purple blotches around his eyes. Examination revealed bilateral periorbital and perioral ecchymosis, purpuric spots along his waist, and waxy papules on his eyelids. In addition, the patient had macroglossia with nodular infiltration and irregular indentations at the lateral margin of his tongue. The patient also had a raised jugular venous pressure and prominent atrial and ventricular waves. Further examination revealed a fourth heart sound over the left ventricular apex, as well as bilateral basal rales...

BACKGROUND: Continuous effort is still provided in designing optimal artificial heart valves with better hemodynamic function and reduced thromboembolic potential. The question is do we have moved forward toward this goal or not. METHODS: A prospective, randomized comparative study was done on 360 patients scheduled for elective mitral valve replacement. Patients were grouped into On-X group (n=180) who received On-X mechanical valve and SJM (n=180) who received St Jude mechanical valve...

This paper provides a comprehensive overview of 3D transesophageal echocardiography still images and movies of mechanical mitral valves, mitral bioprostheses, and mitral valve repairs. Alongside these visual descriptions, the historical overview of surgical and percutaneous mitral valve intervention is described with the special emphasis on the incremental value of 3D transesophageal echocardiography (3DTEE). For each mitral valve intervention, 2D echocardiography, chest x-ray, and fluoroscopy images corresponding to 3DTEE are given...

A key component of image guided interventions is the registration of preoperative and intraoperative images. Classical registration approaches rely on cross-modality information; however, in modalities such as MRI and X-ray there may not be sufficient cross-modality information. This paper proposes a fundamentally different registration approach which uses adjacent anatomical structures with superabundant vessel reconstruction and dynamic outlier rejection. In the targeted clinical scenario of cardiac resynchronization therapy (CRT) delivery, preoperative, non contrast-enhanced, MRI is registered to intraoperative, contrasted X-ray fluoroscopy...

We aim to evaluate the disturbances in mineral metabolism, abnormalities in bone mineral density (BMD), and extraskeletal calcification in newly detected, untreated predialysis stage 4 and 5 chronic kidney disease (CKD) patients at a tertiary care hospital in North India. This is cross-sectional observational study. A total of 95 (68 males, 27 females) newly detected patients underwent clinical evaluation, biochemical assessment [serum calcium, phosphorus, alkaline phosphatase (ALP), albumin, creatinine, intact parathyroid hormone (iPTH), 25- hydroxyvitamin D (25(OH)D)], BMD measurement (at spine, hip, and forearm) by dual-energy X-ray absorptiometry (DXA), lateral abdominal radiograph [for abdominal aortic calcification (AAC)], skeletal survey (to look for any abnormality including fractures), and echocardiography [for any cardiac valvular calcification (CVC)]...
