Electrode positions, transformation coordinates for ECG reconstruction from S-ICD vectors.

The article contains data pertaining to the reconstruction of an 8-lead ECG from 2 subcutaneous implantable cardioverter defibrillator vectors. The location of electrodes on the precordium required for the data collection are detailed; the flow chart for patient selection and exclusion is shown; the summary data of the root mean square error (RMSE) (in microvolts) and Pearson r for the ECG transformation all cases and the pearson correlation for all the leads measured and reconstructed leads are also shown. Detailed background, methodology and discussion can be found in the linked research article

HYBRID SURGICAL RECONSTRUCTION OF AORTA DISSECTION MANIFESTED DURING PREGNANCY

In the article, a brief review provided of various perspectives on the tactics of surgery in thoracic aorta dissection in pregnant and parturient women. Clinical case presented of successful surgery of dissection type A (Stanford) in the puerperant, with good short and middle term results. The aim of clinical case demonstration is to rise awareness on the risks of aorta dissection in pregnant and puerperant women. It also witness for radicality of the “frozen elephant trunk” technology

Parvovirus B19 infection of cultured skin fibroblasts from systemic sclerosis patients.

We read with interest the recent article by Ray and coworkers reporting that human parvovirus B19 infection can induce in vitro invasive properties in normal human synovial fibroblasts . Their study further supports previous observations suggesting that B19 infection could be involved in the pathogenesis of rheumatoid arthritis and other rheumatic disorders, including systemic sclerosis (SSc) . SSc is a connective tissue disease of unknown etiology; its pathogenesis involves overproduction of collagen by altered fibroblasts and alterations of the microvasculature and immune system . Numerous genetic, environmental, and infectious agents have been proposed as possible etiologic factor
