This overview gives an update on the molecular mechanisms, clinical manifestations, diagnosis and therapy of arrhythmogenic cardiomyopathy (ACM). ACM is mostly hereditary and associated with mutations in genes encoding proteins of the intercalated disc. Three subtypes have been proposed: the classical right-dominant subtype generally referred to as ARVC/D, biventricular forms with early biventricular involvement and left-dominant subtypes with predominant LV involvement. Typical symptoms include palpitations, arrhythmic (pre)syncope and sudden cardiac arrest due to ventricular arrhythmias, which typically occur in athletes...

BACKGROUND: Isolated tricuspid valve replacement is rare when performed as a re-operation after a left side operation. It is important to know the factors that determine mortality and morbidity. Tricuspid Annular Plane Systolic Excursion (TAPSE) is a scoring system that is used with non-invasive Doppler echocardiography to determine right ventricular (RV) function. This study analyzed TAPSE scores and adverse outcomes of isolated tricuspid valve surgery in patients with previous cardiac surgery...

Left ventricular non-compaction cardiomyopathy (LVNC) is a clinically heterogeneous disorder characterized by a trabecular meshwork and deep intertrabecular myocardial recesses that communicate with the left ventricular cavity. Several genetic causes of LVNC have been reported, with variable modes of inheritance, including autosomal dominant and X-linked inheritance, but relatively few responsible genes have been identified. A NGS workflow, based on a panel of 95 genes developed for sequencing most prevalent sudden cardiac death-causing genes, was used to make a rapid and costless molecular diagnosis in two siblings with a severe non-compaction cardiomyopathy starting prenatally and leading to rapid cardiac failure...

BACKGROUND: Central nervous system (CNS) melioidosis is notorious because of the difficulty in bacteria eradication and the destruction of brain structures. Early manifestation of CNS melioidosis mimics malignancy or stroke. We present a case of CNS melioidosis that initially manifested as malignancy. CASE DESCRIPTION: A 30-year-old man presented with sudden onset of left limb weakness and seizure. Computed tomography of the brain showed a low-density lesion over the right parietal lobe, and magnetic resonance imaging showed a well-enhanced lobulated lesion...

We report a case of a 18-year-old boy who presented with dyspnea and right upper quadrant abdominal dull pain. According to urgent echocardiography, a dense sessile mass occupied the right ventricule. Tumor resection was performed, followed by further adjuvant therapy. The specimen was histopathologically investigated and eventually diagnosed as metastatic adult hepatoblastoma. We discuss its clinical features and treatment in the light of the current knowledge. It is important for us to be aware that adjuvant chemotherapy might be an effective alternative in the treatment of hepatoblastoma combined with ventricle invasion...

Hypoplastic left heart syndrome (HLHS) is one of the most challenging congenital heart defects which require surgical interventions during neonatal period. Since the 1st successful surgical repair was reported by Norwood et al. more than 30 years ago, some modifications in surgical maneuver [e. g. introduction of right ventricule (RV)-pulmonary artery (PA) shunt] and improvement of perioperative management have brought better outcome for this patient cohort. Recent years our institute have changed the treatment strategy from primary Norwood operation during neonatal period to bilateral PA banding and subsequent Norwood operation during early infantile (we call it as "rapid 2 stage Norwood operation")...

Neither guidelines nor best practices for the treatment of external ventricular drain (EVD) and ventriculoperitoneal shunt infections exist. An antimicrobial regimen with a broad spectrum of activity and adequate cerebrospinal fluid (CSF) penetration is vital in the management of both EVD and ventriculoperitoneal infections. In this case report, we describe the pharmacokinetics of continuous-infusion meropenem for a 2-year-old girl with Serratia marcescens ventriculitis. A right frontal EVD was placed for the management of a posterior fossa mass with hydrocephalus and intraventricular hemorrhage...

Pyogenic ventriculitis is an uncommon and potentially fatal central nervous system infection. Delayed treatment due to non specific clinical symptoms may lead to an unfavorable outcome. Brain magnetic resonance imaging (MRI) plays an important role in the diagnosis of pyogenic ventriculitis. We describe two patients with pyogenic ventriculitis presenting with a pathognomonic MRI finding. The first patient, a 77-year-old female, developed high fever and consciousness disturbance. MR images revealed hyperintense lesions with a fluid-fluid level in the bilateral lateral ventricles on diffusion-weighted images (DWIs) and hypointense lesions on T2-weighted images (T2WIs)...

BACKGROUND: Escherichia coli (E. coli) is the most common causative bacteria of neonatal meningitis, but hematogenous intracranial E. coli infection is rare in adults. Moreover, intracranial abscess formation owing to E. coli, including brain abscesses and subdural empyema formation, is extremely rare. We herein present a case involving a patient with a brain abscess owing to E. coli following a simple renal cyst infection. A review of the literature is also presented. CASE PRESENTATION: A 77-year-old Japanese woman with a history of polymyalgia rheumatica was admitted to our hospital because of persistent fever, right flank pain, and pyuria...

OBJECTIVE: During the course of chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PH) and right ventricular (RV) failure may develop due to elevated afterload of the RV. In those patients, exercise capacity is reduced due to pulmonary and cardiac limitations. We investigated relationships between serum N-terminal of proB-type natriuretic peptide (NT-proBNP) and RV functions with exercise capacity and quality of life in patients COPD. METHODS: An observational case-control study was conducted...

A 70-year-old man, with a history of broad anterior myocardial infarction and repeated several hospitalizations due to heart failure, was referred to our institution for cardiac resynchronization therapy. However, as intravenous implantation of the left ventricular pacemaker lead was not possible, the patient underwent video-assisted thoracoscopic (VAT) implantation. We noted broad myocardial scarring and patent grafts, along with previously bypassed left internal thoracic artery( LITA)-left anterior descending artery (LAD) and right internal thoracic artery (RITA)-D1;thus, the area suitable for implantation of the left ventricule (LV) pacemaker was believed to be restricted...

In the recent years, the Fontan completion rate for hypoplastic left heart syndrome (HLHS) is improved because of the outcome of stage-1 palliation improved. However, there are still problems to be solved to achieve better hemodynamics after Fontan operation in patients with HLHS. The 2 major commandments other than classic 10 commandments are A:"good ventricular function" and B:"low pulmonary vascular resistance". To obtain these 2, the following problems should be rectified. They include residual arch obstruction, impaired right ventricule (RV) function, tricuspid regurgitation, elevated pulmonary vascular resistance, development of aorto-pulmonary collaterals and etc...
