PURPOSE: Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS: We retrospectively reviewed 11 patients treated with one-stage orbital and sinus surgery...

BACKGROUND: Nasal deformity associated with cleft lip and palate is a highly challenging reconstructive problem in rhinoplasty. In the literature, several operative solutions and evaluation methods have been described, however these do not offer a standard procedure for the surgeon. Our aim was to standardize our surgical technique-as much as the uniqueness of each case allowed it-based on the most frequent deformities we had faced; and to evaluate our results via a postoperative patient satisfaction questionnaire...

BACKGROUND: Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. METHODS: It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. RESULTS: There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections...

BACKGROUND: The recognition of RV overpressure is critical to human life, as this may signify morbidity and mortality. Right ventricle (RV) dysfunction is understood to have an impact on the performance of the left ventricle (LV), but the mechanisms remain poorly understood. It is understood that ventricular compliance has the ability to affect cardiac performance. In this study, a bi-ventricular model of the rat heart was used in preference to other, single-ventricle models. Finite element analysis (FEA) of the bi-ventricular model provides important information on the function of the healthy heart...

Optimal hemodynamics in aorta-pulmonary shunt reconstruction is essential for improved post-operative recovery of the newborn congenital heart disease patient. However, prior to in vivo execution, the prediction of post-operative hemodynamics is extremely challenging due to the interplay of multiple confounding physiological factors. It is hypothesized that the post-operative performance of the surgical shunt can be predicted through computational blood flow simulations that consider patient size, shunt configuration, cardiac output and the complex three-dimensional disease anatomy...

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 experiment triggered to early diastole during a brief breath-hold. 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 graphics processing unit-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...

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...
