Multislice/multidetector-row computed tomography (MDCT) is now widely used for noninvasive assessment of coronary arteries, and it may sometimes reveal coronary anomalies. Detection of such anomalies may be relevant both during follow-up and for planning cardiac or coronary surgical/interventional procedures. These anomalies may be missed unless carefully sought. In this paper, we present the MDCT images of a first septal perforator branch originating from the left main coronary artery, which represents an extremely rare coronary anomaly...

Purpose: Analyzing different patterns of maxillary sinus septa in cone-beam computed tomography (CBCT) images and predicting maxillary sinus membrane perforations. Materials and Methods: In this cross-sectional study, CBCT images of 222 patients ranging from 20 to 81 years old were evaluated. One hundred fifty-two patients (93 females and 59 males) who had maxillary sinus septa in axial views were included in this study. Cross-sectional images were used to determine classifications of sinus septa and the risk of membrane perforation using a method modified from Al-Faraje et al...

Coronary artery disease of the septal perforator branches can lead to clinical ischemia and conduction abnormalities. Performing interventional procedures in these vessels is frequently impossible because they are small, which makes it difficult to approach them and to select appropriate equipment. Larger septal perforator branches have been treated percutaneously in a few patients; however, the clinical effectiveness and long-term outcomes are not known. We present our experience in managing obstructive septal perforator branch stenosis in 4 patients...

Ebstein's anomaly is a rare congenital heart disease that presents with apical displacement of the septal and posterior leaflets of the tricuspid valve. It has a wide spectrum of clinical presentations and has been shown to manifest itself any time from birth to adulthood. Our patient is a 43-year-old male with a history of intravenous heroin abuse who presented to the emergency department with worsening shortness of breath and lower extremity edema. He denied any prior cardiac history. A transthoracic echo showed normal left ventricular function, but a large 2...

BACKGROUND: Right ventricular outflow tract (RVOT) stents have been used as palliation in patients with severe tetralogy of Fallot (TOF). Radiofrequency perforation of the RVOT has also been described in patients with pulmonary atresia (PA)/ventricular septal defect (VSD). However, RVOT stenting in conjunction with radiofrequency perforation as a means for establishing reliable pulmonary blood flow in patients with PA/VSD has not previously been reported. OBJECTIVES: Our aim is to report our experience with using perforation of plate-like pulmonary valve atresia combined with stenting of RVOT as an alternative and equally efficacious intervention for infants with PA/VSD, as compared to a surgical pulmonary artery shunt (SPS)...

BACKGROUND: The timing of surgical repair for ventricular septal perforation (VSP) is important because patients are susceptible to bleeding from fragile myocardial tissue or residual shunt during the acute phase of acute myocardial infarction (AMI). This study aimed to assess the results of delayed surgery for VSP performed 2 weeks after AMI. METHODS: In total, 24 consecutive postinfarction patients with VSP (mean age: 72.6±10.4 years; 13 males) underwent operation between May 2003 and June 2016...

We report the case of a 51-year-old female, in whom coronary artery disease such as occlusion of septal perforators was manifested, on the occasion of hospitalization with congestive heart failure. The patient had a history of radiation therapy for a mediastinal tumor 19 years previously. As she had no conventional coronary risk factors, the cause of the coronary artery disease is thought to have been related to the radiation therapy. As survival rates of cancer patients improve as a consequence of therapeutic advances, we should be aware of the possibility of coronary artery disease as a very late complication of radiation therapy, even in patients who have no coronary risk factors...

OBJECTIVES/HYPOTHESIS: Endonasal surgeries are the primary cause of septal perforation (SP). However, trauma, inflammation, infections, neoplasms, or abuse of inhaled drugs can also cause SP. Septal repair is indicated in patients who experience nasal obstruction, crusting, intermittent epistaxis, purulent discharge, or nasal whistling and in those who fail conservative treatment. Multiple approaches have been suggested to repair the SP; however, none has been universally adopted. This study explores the feasibility of repairing a total SP using the pericranial flap (PCF)...

In ascomycete fungi, hyphal cells are separated by perforate septa, which allow cell-to-cell communication. To protect against extensive wound-induced damage, septal pores are sealed by peroxisome-derived Woronin bodies (WBs). The mechanism underpinning WB movement is unknown, but cytoplasmic bulk flow may "flush" WBs into the pore. However, some studies suggest a controlled and active mechanism of WB movement. Indeed, in the wheat pathogen Zymoseptoria tritici cellular ATP prevents WBs from pore sealing in unwounded cells...

BACKGROUND: Quantification of defect size and shunt flow is an important aspect of ventricular septal defect (VSD) evaluation. This study compared three-dimensional echocardiography (3DE) with the current clinical standard two-dimensional echocardiography (2DE) for quantifying defect area and tested the feasibility of real time 3D color Doppler echocardiography (RT3D-CDE) for quantifying shunt volume of irregular shaped and multiple VSDs. METHODS: Latex balloons were sutured into the ventricles of 32 freshly harvested porcine hearts and were connected with tubing placed in septal perforations...

Iatrogenic aortic valve (AV) perforation during non-aortic cardiac operations is a rare complication. The suture-related inadvertent injury to an AV leaflet can produce leaflet perforation with aortic regurgitation after ventricular septal defect repair (VSDR). We report three consecutive patients who had iatrogenic aortic leaflet perforation during VSDR in other hospitals and referred to our hospital for reoperation. In all three cases, the perforated AV leaflets were preserved and repaired by autologous pericardial patch or direct local closure...

H Dixon, F R Datema
Despite the variety of surgical techniques available to close big symptomatic septum perforations, closure rates of 30 to 70% indicate the difficulty of obtaining a good end result. The double meat hook technique is a new endoscopically assisted technique that delivers excellent visualization and control of mucosal flap elevation, extension and suturing. Mucosa from the nasal floor, lateral nasal wall and inferior turbinate bone are valuable donor site extensions. There is no need for additional incisions into the nasal septal mucosa in order to perform a tension-free closure...

We report on an 84-year-old woman with anteroseptal acute myocardial infarction. Emergency coronary angiography revealed the occlusion of proximal left anterior descending artery without collateral circulation, and percutaneous coronary intervention was performed. Two drug eluting stents were implanted, and the procedure was concluded with thrombolysis in myocardial infarction grade 3 without complications. Postoperatively, no murmur was audible on auscultation and no shunt flow was observed on transthoracic echocardiography (TTE), and normal blood pressure was maintained...

At present, surgical septal myectomy is regarded as the "gold standard" treatment for most patients with obstructive hypertrophic cardiomyopathy (HCM) and drug-refractory symptoms. However, the best results are obtained by those surgeons who have extensive experience with this operation at a small number of referral centers. In the mid-1990s, percutaneous alcohol septal ablation was introduced as an alternative to myectomy to reduce LV outflow gradient and heart failure symptoms in patients with obstructive HCM...

OBJECTIVES: Electrifying a coronary guidewire may be a simple escalation strategy when trans-septal needle puncture is unsuccessful. BACKGROUND: Radiofrequency energy to facilitate trans-septal puncture through a dedicated device is costly and directly through a trans-septal needle may be less safe. Our technique overcomes these limitations. METHODS: The technique was used in patients when trans-septal needle penetration failed despite excessive force or tenting of the atrial septum...

Filamentous cyanobacteria have developed a strategy to perform incompatible processes in one filament by differentiating specialized cell types, N2-fixing heterocysts and CO2-fixing, photosynthetic, vegetative cells. These bacteria can be considered true multicellular organisms with cells exchanging metabolites and signaling molecules via septal junctions, involving the SepJ and FraCD proteins. Previously, it was shown that the cell wall lytic N-acetylmuramyl-L-alanine amidase, AmiC2, is essential for cell-cell communication in Nostoc punctiforme...
