OBJECTIVE: To develop a novel method for rapid myocardial T1 mapping at high spatial resolution. METHODS: The proposed strategy represents a single-shot inversion-recovery (IR) experiment triggered to early diastole during a brief breathhold. The measurement combines an adiabatic inversion pulse with a real-time readout by highly undersampled radial FLASH, iterative image reconstruction and T1 fitting with automatic deletion of systolic frames. The method was implemented on a 3 T MRI system using a GPU-equipped bypass computer for online application...

BACKGROUND: WE AIMED TO PROSPECTIVELY EVALUATE THE: use of 3-dimensional printing (3DP) for the percutaneous transcatheter closure of a secundum atrial septal defect (ASD) with rim deficiency less than 5 mm. METHODS: Patients with ASD were scanned using multi-slice computed tomography to acquire raw data for virtual 3DP reconstruction models. Different ASD occluders were tried on the 3DP models to select the optimal size for intraoperative use. The patients were followed up 1 month postoperatively, and 3DP models were again manufactured to observe the operative effects...

CONTEXT: Many reconstructive techniques have been proposed to prevent postoperative cerebrospinal fluid (CSF) leakage after trans-sphenoidal pituitary surgery. However, no total agreement has been reached to the best technique. AIM: Assessment of the efficacy of sellar repair with autologous muscle and composite septal cartilage grafts for treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain...

BACKGROUND: Epicardial pacing wires (EPWs) are commonly employed for diagnosis and treatment of arrhythmia in the acute phase after cardiac surgery. Although rare, retained EPWs may cause mild-to-catastrophic complications. The present case demonstrates hemopericardium caused by a mobile retained EPW. METHODS: A 49-year-old woman presented to our emergency department with clinical signs of impending cardiac tamponade. She had undergone ventricular septal defect repair 7 years before this admission...

The evolution of complexly folded septa in ammonoids has long been a controversial topic. Explanations of the function of these folded septa can be divided into physiological and mechanical hypotheses with the mechanical functions tending to find widespread support. The complexity of the cephalopod shell has made it difficult to directly test the mechanical properties of these structures without oversimplification of the septal morphology or extraction of a small sub-domain. However, the power of modern finite element analysis now permits direct testing of mechanical hypothesis on complete, empirical models of the shells taken from computed tomographic data...

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant multi-systemic disease that exhibits increasing penetrance with age. Some patients present with severe life-threatening epistaxis which is intractable to all common treatment modalities. A 63-year-old female patient with hereditary hemorrhagic telangiectasia (HHT) presented with recurrent life-threatening epistaxis that required repeated transfusions despite multiple embolizations and septodermoplasty. Previous septodermoplasty failed due to septal perforation...

The unilateral absence of a proximal pulmonary artery (UAPPA) is rare and is most frequently accompanied by cardiovascular anomalies such as tetralogy of Fallot or septal defects. We report a patient with truncus arteriosus with UAPPA in which we performed a two-stage surgical repair. During the first palliative operation, a right modified Blalock-Taussig shunt was constructed to develop the hypoplastic right pulmonary artery. At 10 months, the patient underwent patch closure of a ventricular septal defect with integration of both pulmonary arteries, and reconstruction of the right ventricular outflow tract using a conduit...

INTRODUCTION: Iatrogenic ventricular septal defect is a rare complication after the surgical replacement of cardiac valves. Small defects may have no hemodynamic significance or remain unremarked at the end of the surgical procedure. Understanding of the valvular anatomy alone is not always enough to avoid such complications, especially in the hands of young surgeons. PRESENTATION OF CASE: We present a case of iatrogenic ventricular septal defect that developed early after the surgical closure of a hemodynamically significant mitral paravalvular leak...

The Konno operation consists of a prosthetic aortic valve replacement by using an anterior enlargement of the small aortic annulus. The original procedure includes a longitudinal incision in the aortic septum placed near the midpoint between the two coronary ostia, a vertical incision in the outflow tract of the right ventricle to join the septal incision, prosthetic aortic valve replacement, and patch reconstruction of the outflow tracts of both ventricles by means of a fusiform Dacron patch. The concept of this operation has been applied in other complex operations, such as modified Konno operation, Ross-Konno operation, and aortic valve replacement after arterial switch operation...

A combination of tetralogy of Fallot( TOF) and total anomalous pulmonary venous return(TAPVR) is rare and results in chronic volume and pressure load of the right side of the heart and underfilling of the left heart. We report a successful 2-staged surgical correction of TOF associated with TAPVR and atrial septal defect. The patient was unsuitable for total primary intracardiac correction because the volume of the left ventricle was considered to be small. First, repair of anomalous pulmonary venous return and palliative right ventricle outflow tract reconstruction were simultaneously performed in 2 months of birth...

INTRODUCTION: The interplay between electrical activation and mechanical contraction patterns is hypothesized to be central to reduced effectiveness of cardiac resynchronization therapy (CRT). Furthermore, complex scar substrates render CRT less effective. We used novel cardiac computed tomography (CT) and noninvasive electrocardiographic imaging (ECGI) techniques in an ischemic dyssynchronous heart failure (DHF) animal model to evaluate electrical and mechanical coupling of cardiac function, tissue viability, and venous accessibility of target pacing regions...

The management of double-outlet right ventricle associated with anatomically noncommitted ventricular septal defect constitutes a surgical challenge. The limits for, and the specific outcomes after anatomical vs univentricular repair still remain to be established. Between 1993 and 2011, 36 consecutive patients presenting with double-outlet right ventricle or noncommitted ventricular septal defect (21 inlet, 10 muscular, and 5 central perimembranous) and 2 adequately sized ventricles underwent surgical repair at 2 centers...

BACKGROUND: In patients undergoing transnasal endoscopic sellar surgery, an analysis of risk factors and predictors of intraoperative and postoperative cerebrospinal fluid leak (CSF) would provide important prognostic information. METHODS: A retrospective review of patients undergoing endoscopic sellar surgery for pituitary adenomas or craniopharyngiomas between 2002 and 2014 at 7 international centers was performed. Demographic, comorbidity, and tumor characteristics were evaluated to determine the associations between intraoperative and postoperative CSF leaks...

Less invasive techniques are commonly used to treat patients with anatomically suitable secundum atrial septal defects; however, repair of more complex atrial septal defects are still performed through sternotomy. Cosmetically appealing periareolar incisions have been used in breast reconstructive surgery and may provide an esthetically superior alternative to the anterolateral minithoracotomy incision used in minimally invasive cardiac surgery. We describe a patient with an unroofed coronary sinus atrial septal defect who underwent successful minimally invasive, endoscopic repair of this defect with autologous pericardial baffle reconstruction of the coronary sinus roof and closure of the interatrial communication through a periareolar approach...

The surgeons performing rhinoplasty found Graft selection the greatest challenge. To avoid an immune response the preferred choice thus far for nasal reconstruction would be autograft compared to allograft due to its lower rate of rejection. We have evaluated 30 patients who underwent open rhinoplasty and We used conchal and septal cartilaginous grafts in various forms by the open approach to correct various nasal deformities compared our experience regarding the operative technique, graft availability, indications, and limitations...

The aim of this study is to determine the effectiveness and biocompatibility of polypropylene mesh for the repair of nasal septal perforations in an animal model on rabbits. A full-thickness nasal septal perforation with a diameter of nearly 10 × 10 mm was created on 12 rabbits, and then the perforation was reconstructed with two different methods. We used mucosal flaps and polypropylene mesh as an interpositional graft in group 1. Only mucosal flaps were used for reconstruction and are identified as group 2...
