Left main reconstruction as an alternative method to CABG after primary PCI complication

AbstractLeft main coronary artery disease is rare, accounting for 1% of all coronary artery disease and traditionally, is treated by coronary artery bypass grafting. We report our experience and five years follow up, after a coronary osteal surgical plasty in a young man who referred to our center with an anterior myocardial infarction

Uncommon Cardiomyopathies

Anderson-Fabry Disease (AFD) is an X-linked recessive lysosomal disorder, leading to multisystemic disease because of abnormal glycosphyngolipids widespread accumulation, the result of α-galactosidaseA deficient activity. Cardiac involvement is common; includes left ventricular hypertrophy and gradually impairing cardiac function. Although the disease is unveiled in childhood and culminates in cardiac, cerebrovascular and end-stage renal disease, diagnosis is often delayed or missed. Recently established enzyme replacement therapy (ERT) may improve most of the disease’s manifestations. Early diagnosis is thus crucial for AFD patient management. Isolated non-compaction of the ventricular myocardium (IVNC) is a rare congenital form of cardiomyopathy. It is characterized by the postnatal persistence of the embryonic pattern of myoarchitecture, consistent of prominent trabeculations and deep intertrabecular recesses, and assumed to occur as a consequence of intrauterine arrest of myocardial compaction. Contemporary diagnosis has been facilitated by the introduction of specific morphologic criteria by echocardiography and magnetic resonance imaging. Management issues revolve around the management of heart failure, arrhythmias and thromboembolic events in order to prevent the significant morbidity and even mortality that has been associated with this entity. Significant overlapping with many other forms of cardiomyopathies suggest that non-compaction may be a morphologic trait rather than a distinct cardiomyopathy

Mid Jurassic to earliest Cretaceous (Callovian-Ryazanian) radiolaria of the North Sea Basin

The North Sea is a series of interconnecting sedimentary basins, located on the northwest margin of the Eurasian tectonic plate. The complex geological setting and sedimentation patterns of the North Sea Basin have been reviewed as an introduction to this study. Eleven wells/exposures from this area, spanning the Mid Jurassic (Callovian) to Earliest Cretaceous (Ryazanian) time interval, have been examined for radiolaria. The inclusion of 2 more wells from the Norwegian and Barents Seas has been used for comparative purposes and contributed to the taxonomic understanding of the less well-preserved North Sea radiolarians. Previous work on radiolarians from around the world for the studied interval has been recorded and a database/list has been produced. The state of preservation of the radiolarian assemblages has been discussed and Electron Microprobe analyses have been performed. In some instances the siliceous radiolarian skeletons have been replaced by other minerals, most commonly calcite or pyrite. A total of 129 species/morphotypes from 392 samples has been described and illustrated with scanning electron and light microscope micrographs. The occurrence of these taxa in previous studies in the literature is reviewed to aid interpretation of the North Sea assemblages, which exhibit some affinity with other Boreal assemblages. By employing careful processing techniques and taking into account the commonly poor preservation of radiolarians, their biostratigraphic value has been demonstrated by means of the Unitary Associations method. The ranges of 52 taxa have been used for computer treatment with the BioGraph program, from which 18 Unitary Associations have been established. These were grouped into 5 zones which were correlated to the standard ammonite zones: Biozone 1. early Callovian to mid Kimmeridgian; 2: mid Kimmeridgian to Early Volgian. 3: Early Volgian to Mid Volgian. 4: Mid Volgian to latest Mid Volgian. 5: latest Mid Volgian to Late Ryazanian. The application of radiolaria to stratigraphic problems in the North Sea Basin is reviewed and suggestions made for future work
