INTRODUCTION: Lipin-1 deficiency is a major cause of rhabdomyolysis that are precipitated by febrile illness. The prognosis is poor, with one-third of patients dying from cardiac arrest during a crisis episode. Apart from acute rhabdomyolysis, most patients are healthy, showing normal clinical and cardiac ultrasound parameters. PATIENTS AND METHODS: We report cardiac and exercise examinations of 8 children carrying two LPIN1 mutations. The examinations were performed outside of a myolysis episode, but one patient presented with fever during one examination...

BACKGROUND: Estimation of cardiac output (CO) is essential in the treatment of circulatory unstable patients. CO measured by pulmonary artery catheter thermodilution is considered the gold standard but carries a small risk of severe complications. Stroke volume and CO can be measured by transesophageal echocardiography (TEE), which is widely used during cardiac surgery. We hypothesized that Doppler-derived CO by 3-dimensional (3D) TEE would agree well with CO measured with pulmonary artery catheter thermodilution as a reference method based on accurate measurements of the cross-sectional area of the left ventricular outflow tract...

BACKGROUND: Xenograft conduits have been used successfully to repair congenital heart defects, but are prone to failure over time. Hence, in order to improve patient outcomes, better xenografts are being developed. When evaluating a conduit's performance and safety it must first be compared against a clinically available control in a large animal model. The study aim was to evaluate a clinically available xenograft conduit used in right ventricular outflow tract (RVOT) reconstruction in a sheep model...

Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus. A case involving caseous calcification, a rare variant of MAC is presented. This variant which has a benign course can present as an intracardiac mass and needs to be differentiated from more sinister causes of calcified cardiac masses such as tumor, abscess, and infective vegetation. Often, this requires multimodality imaging with echocardiography, computed tomography, and magnetic resonance imaging. Features of caseous calcification of the mitral valve on these imaging modalities are reviewed as the associations and clinical features...

Pheochromocytomas are rare neuroendocrine tumors, with published incidence of 2 to 8 cases per million patients per year. The extension of these tumors into the vena cava and right atrium is rarely seen. Transesophageal echocardiography may be invaluable to delineate tumor extent and characteristics, which in turn may provide a useful tool to guide intraoperative surgical approach to these uncommon masses. In the case presented in this article, we describe the role of transesophageal echocardiography in guiding a safe and complete, excision of an invasive pheochromocytoma without embolization of tumor components...

Radio frequency (RF) ablation of the myocardium is used to treat various cardiac arrhythmias. The size, spacing, and transmurality of lesions have been shown to affect the success of the ablation procedure; however, there is currently no method to directly image the size and formation of ablation lesions in real time. Intracardiac myocardial elastography (ME) has been previously used to image the decrease in cardiac strain during systole in the ablated region as a result of the lesion formation. However, the feasibility of imaging multiple lesions and identifying the presence of gaps between lesions has not yet been investigated...

BACKGROUND: Safe and successful radiofrequency catheter ablation depends on creation of transmural lesions without collateral injury to contiguous structures. Near-field ultrasound (NFUS) imaging through transducers in the tip of an ablation catheter may provide important information about catheter contact, wall thickness, and ablation lesion formation. METHODS AND RESULTS: NFUS imaging was performed using a specially designed open-irrigated radiofrequency ablation catheter incorporating 4 ultrasound transducers...

Intracardiac thrombus occurs in 1.2%-6.3% of patients undergoing orthotopic liver transplant and is associated with a high mortality rate. The pathophysiology and risk factors for development of this complication are not well understood. No consensus treatment guidelines exist, and specific therapies are associated with serious risks. We present the timely and successful use of a Poole tip surgical suction device advanced into the right atrium through a cavotomy created in the inferior vena cava to remove a large right atrial thrombus during liver transplant...

Papillary ibroelastomas are small benign intracardiac tumors known for their embolic potential. Since the introduction of echocardiography with improved resolution and transesophageal imaging techniques, they are being increasingly detected in clinical practice. In recent series, papillary fibroelastoma is considered the most frequent benign tumor of the heart. Our objective was to analyze characteristics and midterm surgical outcome of histologically-confirmed cases of papillary fibroelastoma. We conducted a retrospective study on patients with cardiac tumors submitted to surgical excision between June 1992 and February 2017...

A 63 year old female presented to hospital with progressive exertional dyspnoea over a 6 month period. In the year preceding her admission, she reported an intercurrent history of abdominal pain, diarrhoea and weight loss. She was found to be hypoxic, the cause for which was initially unclear. A ventilation-perfusion scan identified a right-to-left shunt. Transoesophageal echocardiography (TOE) demonstrated a significant right-to-left intracardiac shunt through a patent foramen ovale (PFO); additionally severe tricuspid regurgitation was noted through a highly abnormal tricuspid valve...

BACKGROUND: Leadless pacemaker can be considered as a technical revolution in cardiac pacing devices, with clear advantages over conventional pacemakers in overcoming all lead related complications. However, the management of these devices once they reach the end of life of the battery is still controversial. In the next years there will be an increase in the need to define a clear strategy in the management of leadless PM once they reach their EOL. Safe extraction of these devices will define in a great manner this strategy METHODS: We performed the extraction of three functioning Nanostim leadless pacemaker prophylactically in two females and one male patients part of the Nanostim battery depletion field action recommendation...

Composite tumors of cardiac myxoma and malignant lymphoma are extremely rare, with 11 of such cases reported in the literature. A 44-year-old man presented to us with abrupt right lower leg pain. A computed tomography angiogram revealed segmental obstruction of the right common femoral artery, and embolectomy was performed. The embolectomy specimen contained several clusters of degenerated round/oval atypical cells in the fibrinous or myxoid background. Immunohistochemical examination revealed that these atypical cells were negative for cytokeratin and non-specifically expressed CD45...
