BACKGROUND: Surgical treatment of complicated aortic valve endocarditis often is challenging, even for experienced surgeons. We aim at demonstrating a standardized surgical approach by stentless bioprostheses for the treatment of aortic valve endocarditis complicated by paravalvular abscess formation. METHODS: Sixteen patients presenting with aortic valve endocarditis (4 native and 12 prosthetic valves) and paravalvular abscess formation at various localizations and to different extents were treated by a standardized approach using stentless bioprostheses...

Down syndrome occurs more frequently in the offsprings of older pregnant women and may be associated with atrioventricular septal defect. This refers to a broad spectrum of malformations characterized by a deficiency of the atrioventricular septum and abnormalities of the atrioventricular valves caused by an abnormal fusion of the superior and inferior endocardial cushions with the midportion of the atrial septum and the muscular portion of the ventricular septum.

Sinonasal schwannomas constitute 4% of head and neck nerve sheath tumours; however, schwannomas involving the nasal septum are quite rare. We present a 57-year-old male patient with nasal septal schwannoma who was managed successfully by endoscopic excision. 32 cases of septal schwannoma have been reported so far in the literature. This report discusses certain peculiar features exhibited by schwannomas of the nasal septum. Septal schwannoma does not show any age, sex or side predilection. However, they tend to involve posterior part of the septum and presumed to arise from the nasopalatine branch of the trigeminal nerve...

To describe the fetal regional myocardial strain rate in the membranous ventricular septum across gestation and to determine their predictive value for a complete membranous ventricular septum (without defect) after delivery. In 1150 fetuses, the peak systolic strain rate (SRs), peak early diastolic strain rate (SRe) and peak late diastolic strain rate (SRa) in the membranous ventricular septum were measured at four time points across gestation (18-20, 24-26, 30-32 and 36-38 weeks). The integrity of the interventricular septum was examined at 12 weeks' postnatal age...

Glomangiopericytoma is a rare vascular neoplasm characterised by a pattern of prominent perivascular growth with myoid phenotype. It is categorised as a borderline low-malignancy tumour by WHO and accounts for less than 0.5% of all sinonasal tumours. After curative resection, patients of glomangiopericytoma need long-term endoscopic follow-up due to high risk of recurrence.We report a case of a 23-year-old man complaining of nasal obstruction off and on and frequent epistaxis. A reddish mass in the right nasal cavity was observed on endoscopy and treated with endoscopic excision...

Interrupted aortic arch (IAA) is a rare congenital malformation defined as complete discontinuity between ascending and descending parts of aorta. We present a case of IAA, which was referred to us due to dilatation of proximal and mid parts of his thoracic aorta accompanied by narrowing of aorta proximal to the branching of the left subclavian artery. Further evaluation revealed interruption of aorta at the proximal part of descending thoracic aorta by a transverse septum along with several collateral formations...

Lipoma is very common benign tumor of adipose tissue, but its presence in the oral cavity is rare. Fibrolipoma is a histological variant of lipoma that affects the buccal mucosa and nasal septum in the orofacial region and causes functional and cosmetic issues. However, this lesion has not been reported on the upper lip and may be confused with other soft tissue lesions of children. Hence, accurate histopathological examination of lipomas is important for a correct treatment plan. The purpose of this report is to describe the case of an 11-year-old boy with fibrolipoma of the upper lip...

BACKGROUND: Left atrial decompression is considered in patients with symptomatic heart failure with preserved ejection fraction (HFpEF). We aimed to evaluate the feasibility and efficacy of transcatheter generation of a restrictive atrial septum communication to manage HFpEF from infancy to adulthood with cardiomyopathy and congenital heart defect. METHODS AND RESULTS: From June 2009 to December 2016, 24 patients (50% with an age less than 16 years) with HFpEF were palliated; NYHA-/Ross class IV (n = 10); median systemic ventricular ejection fraction 64 (range 35-78) %...

BACKGROUND: Making a specific diagnosis of pancreatic cysts preoperatively is difficult. The new disposable Moray micro forceps biopsy (MFB) device allows tissue sampling from the pancreatic cyst wall/septum and aims to improve diagnosis. This study compares the diagnostic performance of the MFB with the current conventional analysis of pancreatic cyst fluid (PCF). METHODS: A total of 48 patients sampled with MFB were identified. Cysts were classified as mucinous on PCF based on extracellular mucin/mucinous epithelium, carcinoembryonic antigen (CEA) levels ≥192 ng/mL, or KRAS/GNAS mutation...

OBJECTIVES: Ventricular pacemaker stimulation may cause deterioration of hemodynamics in patients with left-ventricular hypertrophy following aortic valve replacement. Since the diastolic function is often impaired, it remains unclear which heart rate best optimizes cardiac output. Low heart rates are suggested to treat impaired diastolic function chronically, but it is possible that cardiac output may be augmented by increasing the heart rate in patients with a fixed stroke volume (SV)...

BACKGROUND: Multiform fascicular tachycardia (FT) was recently described as a ventricular tachycardia (VT) that has a reentrant mechanism using multiple fascicular branches and produces alternate fascicular VT forms. Ablating the respective fascicle may cause a change in the reentrant circuit resulting in a change in morphology. Ablation of the septal fascicle is crucial for successful treatment. OBJECTIVES: To describe four cases of FT in which ablation induced a change in QRS morphologies and aggravated clinical course...

Effect of natural complex of cytokines with activity of IL-1, IL-2, IL-6, TNF, MIF, and GTFβ on the structure and metabolism of conduction cardiomyocytes was assessed in the control and under acute experimental aortic stenosis. After systemic administration of the cytokine complex in the control, structural abnormalities were revealed in a relatively low number of conduction cardiomyocytes; their relative number increased in the left ventricle and interventricular septum. When the complex was administered against the background of aortic stenosis, morphological changes in the conduction system were seen in a significant number of cells with their plasma imbibition, especially in the left ventricle and interventricular septum...

The acquisition of good contact force for radiofrequency catheter ablation of ventricular premature complexes (VPCs) originating from the basal septum of the left ventricle (LV) is often difficult. We describe a case of VPCs originating from the basal septum of the LV, which were successfully eliminated by applying radiofrequency at the right atrium (RA) side of the atrioventricular septum (AVS) without causing any significant impairment of atrioventricular conduction because the ablation catheter could obtain better contact force through the RA approach...

Gonadotropin-releasing hormone (GnRH) is a decapeptide involved in the regulation of reproduction in all mammals, but the distribution of GnRH neurons within the brain varies widely among species. The objective of the present study was to characterize the number and distribution of GnRH neurons in the hypothalamus and preoptic area of llamas, an induced ovulator. The brains of female llamas (n = 4) were fixed, frozen and sectioned serially every 50 microns in the transverse (coronal) plane. Every 10th section was stained for immunohistochemical detection of GnRH-positive neuron cell bodies and fibers by incubation with 3,3'-diaminobenzidine...

It is known that patients with rheumatoid arthritis (RA) have a higher risk of coronary heart disease and sudden cardiac death. Abnormalities in cardiac geometry appear to be involved in the setting of the cardiovascular risk, but it has never been specifically investigated in RA. We enrolled 44 patients with RA compared to 131 subjects without RA (normal, N): The RA aged between 18 and 70 years (mean 48.3 ± 2.1), 25 females, BMI 27.6 ± 0.9; N, of equal age (48.6 ± 1.2, n.s.), included 80 females (BMI 26...
