Measuring left ventricular mechanical dyssynchrony from ECG-gated SPECT myocardial perfusion imaging.
Chen J, Garcia EV, Henneman MM, Bax JJ, Boogers MJ, Trimble MA, Borges-Neto S, Velazquez EJ, Iskandrian AE
Cardiac resynchronization therapy (CRT) has shown benefits in patients with severe heart failure. The traditional criteria to select patients for CRT (New York Heart Association [NYHA] class III or IV, depressed left ventricular [LV] ejection fraction, and prolonged QRS duration) result in at least 30% of the selected patients with no response to CRT. Recent studies with echocardiography have shown that the presence of LV dyssynchrony is an important predictor for response to CRT. However, the r...

Specificity and functional interaction of the polymerase complex proteins of human and avian metapneumoviruses.
de Graaf M, Herfst S, Schrauwen EJA, Choi Y, van den Hoogen BG, Osterhaus ADME, Fouchier RAM
Human metapneumovirus (HMPV) and avian metapneumovirus (AMPV) have a similar genome organization and protein composition, but a different host range. AMPV subgroup C (AMPV-C) is more closely related to HMPV than other AMPVs. To investigate the specificity and functional interaction of the polymerase complex proteins of human and avian metapneumoviruses, a minireplicon system was generated for AMPV-C and used in combination with minireplicon systems for HMPV lineages A1 and B1. Viral RNA-like mol...

Early atrial septal defect surgery due to a bronchogenic cyst causing congestive heart failure by left atrium compression.
Mosquera VX, Rijlaarsdam M, Filippini L, Hazekamp MG
We report on an uncommon case of a 10-month-old patient who required early surgical closure of an ostium secumdum atrial septal defect due to the concomitant presence of a big subcarinal bronchogenic cyst compressing the left atrium and, therefore, increasing the left-to-right shunt. It led to refractory congestive heart failure symptoms, establishing thereby an earlier indication of surgical treatment.

B and T cell imbalances in CSF of patients with Hu-antibody associated PNS.
de Graaf M, de Beukelaar J, Bergsma J, Kraan J, van den Bent M, Klimek M, van Norden Y, Kusuma A, Smitt PS, Gratama JW
In paraneoplastic neurological syndromes associated with Hu-antibodies (Hu-PNS) an important role for cellular immunity is hypothesized. We characterized the cerebrospinal fluid (CSF) pleocytosis in Hu-PNS patients by assessing the major lymphocyte subsets by flow cytometry. The B cell subset in the CSF of Hu-PNS patients showed a significant absolute (approximately 20x) and relative (approximately 3x) expansion, while the numbers of CD4+ T cells, CD8+ T cells and NK cells only showed an absolut...

Genetic complementation of human muscle cells via directed stem cell fusion.
Gonçalves MA, Swildens J, Holkers M, Narain A, van Nierop GP, van de Watering MJ, Knaän-Shanzer S, de Vries AA
Duchenne muscular dystrophy (DMD) is caused by mutations in the X chromosome-linked DMD gene, which encodes the sarcolemma-stabilizing protein-dystrophin. Initial attempts at DMD therapy deployed muscle progenitor cells from healthy donors. The utilization of these cells is, however, hampered by their immunogenicity, while those from DMD patients are scarce and display limited ex vivo replication. Nonmuscle cells with myogenic capacity may offer valuable alternatives especially if, to allow auto...

Development of the cardiac conduction system and the possible relation to predilection sites of arrhythmogenesis.
Jongbloed MR, Mahtab EA, Blom NA, Schalij MJ, Gittenberger-de Groot AC
The cardiac conduction system (CCS) encompasses a complex system responsible for the coordinated contraction of the heart. In the developing heart, as well as in the adult heart, tissues of the (putative) CCS are characterized by different properties than the surrounding working myocardium, which can be observed on a histological level, as well as by the expression patterns of several immunohistological and molecular markers. In recent years, many markers have been studied that have helped to el...

Inflammatory aneurysm of the common iliac artery mimicking appendicitis.
Mieog JS, Stoot JH, Bosch JJ, Koning OH, Hamming JF
Isolated inflammatory aneurysm of the common iliac artery is a rare condition. Previously reported cases presented with urologic complications owing to entrapment of the ureter in the perianeurysmal fibrosis. We report a case of a healthy young man who presented with acute abdominal pain in the right lower quadrant without urologic complications mimicking acute appendicitis. The pain was caused by an isolated inflammatory aneurysm of the right common iliac artery measuring 4 cm in diameter. Thre...

Cardiac malformations and myocardial abnormalities in podoplanin knockout mouse embryos: Correlation with abnormal epicardial development.
Mahtab EA, Wijffels MC, Van Den Akker NM, Hahurij ND, Lie-Venema H, Wisse LJ, Deruiter MC, Uhrin P, Zaujec J, Binder BR, Schalij MJ, Poelmann RE, Gittenberger-De Groot AC
Epicardium and epicardium-derived cells have been shown to be necessary for myocardial differentiation. To elucidate the function of podoplanin in epicardial development and myocardial differentiation, we analyzed podoplanin knockout mouse embryos between embryonic day (E) 9.5 and E15.5 using immunohistochemical differentiation markers, morphometry, and three-dimensional reconstructions. Podoplanin null mice have an increased embryonic lethality, possibly of cardiac origin. Our study reveals imp...

Ablation of ventricular tachycardia in patients with structural heart disease.
Zeppenfeld K, Stevenson WG
Catheter ablation is an important therapeutic option for controlling recurrent ventricular arrhythmias in patients with heart disease. Although implantable defibrillators are generally first line therapy in this patient population, a substantial number of patients require additional therapy with either antiarrhythmic drugs, ablation, or both. Studies of mapping and ablation have produced further insights into pathophysiologic mechanisms of these arrhythmias, which are now well characterized. The...
