RATIONALE: Congenital ventricular diverticulum is a rare cardiac malformation with a prevalence of about 0.26% in unselected adult patients during other diagnostic procedures. Ventricular arrhythmia originating from outflow tract diverticulum is even rarer and its etiology, epidemiology and proper treatment still remain controversial. PATIENT CONCERNS: We present 2 cases of isolated outflow tract diverticulum incidentally revealed by cardiac angiography during catheter ablation for ventricular arrhythmia...

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy occurring in upper limbs. The etiology, however, has not been fully understood yet. Median nerve could be compressed by either increase of carpal tunnel pressure (CTP) or direct impingement when it is forced toward to carpal ligament especially in wrist flexion leading to CTS development. Thus, the increase of carpal tunnel pressure is considered an important role in CTS development. It has been identified that forces applied to the palm would affect the CTP...

Scrotal migration of peritoneal end of ventriculo-peritoneal (VP) shunt into the patent processus vaginalis (PPV) is a rare complication. Its exact incidence is not mentioned in the literature till date. This may be because of the rarity of this complication, and also because all previous articles related to the complication were case reports. We, in our series, had an incidence of 0.9%. This prospective study has been conducted on 437 patients in the age group of 1 month-3 years who underwent VP shunt for hydrocephalus over a period of 5 years from 2007 to 2011...

We sought to compare pulmonary flow hemodynamic indices obtained by Fick and thermodilution catheterization techniques with phase-contrast MRI (PC-MRI) in children with diverse etiologies of pulmonary arterial hypertension (PAH). Calculation of pulmonary flow ([Formula: see text]) using the Fick principle in most catheter laboratories relies on an estimate of oxygen consumption which may limit its reliability. Flow hemodynamic indices acquired from thirty patients with PAH who underwent successful same-day PC-MRI and catheterization were evaluated for absolute and percent bias...

REVIEW
Char M Witmer, Clifford M Takemoto
Pediatric hospital acquired venous thromboembolism (HA-VTE) is an increasing problem with an estimated increase from 5.3 events per 10,000 pediatric hospital admissions in the early 1990s to a current estimate of 30-58 events per 10,000 pediatric hospital admissions. Pediatric HA-VTE is associated with significant morbidity and mortality. The etiology is multifactorial but central venous catheters remain the predominant risk factor. Additional HA-VTE risk factors include both acquired (recent surgery, immobility, inflammation, and critical illness) and inherited risk factors...

Interscalene regional anesthesia is an established and highly effective procedure; however, it represents an increased level of risk due to the close proximity of anatomical structures, such as the cervical spinal cord and many vessels. Furthermore, due to inadvertent placement of a catheter close to the cervical spinal cord or into a vessel, as opposed to a single shot injection technique, it remains a latent danger until it is removed. This article describes seven  cases of misplaced catheters. The etiology and symptoms are discussed as well as recommendations regarding the prevention of catastrophic complications...

BACKGROUND: Catheter ablation is now a mainstay of therapy for ventricular arrhythmias (VAs). However, there are scenarios where either physiological or anatomical factors make ablation less likely to be successful. OBJECTIVE: The purpose of this study was to demonstrate that cardiac sympathetic denervation (CSD) may be an alternate therapy for patients with difficult-to-ablate VAs. METHODS: We identified all patients referred for CSD at a single center for indications other than long QT syndrome and catecholaminergic polymorphic ventricular tachycardia who had failed catheter ablation...

Thrombosis of the inferior vena cava (IVC) continues to be a rare event, and there is a scarcity of evidence with regard to its etiology. One source for IVC thrombosis is external compression from adjacent structures. In this case series, we present 1 case of IVC thrombosis caused by a severely distended bladder and a case of external iliac thrombosis caused by external compression from an abnormally enlarged uterus. The treatment of each case is varied and included novel oral anticoagulation, catheter-directed thrombolysis in conjunction with mechanical thrombectomy, or a combination of these...

Cerebral air embolism (CAE) is a potentially fatal iatrogenic complication related to common procedures including central venous catheter (CVC) removal. We report an interesting case of CAE related to CVC removal that was further complicated with status epilepticus. Neuroimaging of CAE and status epilepticus could pose diagnostic dilemmas and require consideration of wide diagnostic differentials. We discuss the clinical presentation, mechanism, and diagnostic approach, especially neuroimaging to differentiate various etiologies in CAE patients...

The hypervirulent K1 serotype Klebsiella pneumoniae is responsible for a new invasive syndrome, typically associated to hepatic abscesses with extra-hepatic complications. Initially described in Taiwan, it has significantly spread to several Asian countries and more recently to Europe and North America, thus constituting an emerging and global problem. The authors describe a case report of a 64-years-old portuguese caucasian woman without any previous diseases or epidemiological risk factors such as trips or contact with Asian products or population, diagnosed with a pyogenic liver abscess with pleural effusion caused by this hyper-virulent strain...
