The localization of the stretch sensitivity and myogenic automatism in the systemic heart of Octopus vulgaris has been studied on an isolated preparation in which the ventricle was zoned by ligatures. Each region has been submitted to two different levels of internal hydrostatic pressure (1 and 2 kPa). Only the two atrio-ventricular regions were able to contract regularly when submitted to inte...
We represent a fatal case of atrio esophageal fistula that presented as upper GI bleed. The case was complicated by rapidly progressing multi organ dysfunction syndrome and eventual death. This was an iatrogenic complication of an elective procedure.
The association between calcific aortic and mitral heart disease and atrio-ventricular block is well recognized especially since Yater and Cornell (1935) demonstrated the spread of calcification from the valve into the nearby conduction tissue. Recently Sellers et al. (1963) have pointed out the risk of damage to the same area during insertion of a prosthetic aortic valve. On the other hand Mah...
Torsades de pointes is a potentially life threatening form of rapid, polymorphic ventricular tachycardia. Literally meaning “twisting of the points”, torsades de pointes is electrocardiographically characterized by QRS axis undulations over runs of several beats, with a specific twist of the QRS complex around the isoelectric baseline. The definition also requires that an abnormal QT-prolongati...
A 75-year-old male, known to have achalasia, was admitted to the intensive care unit with massive upper gastrointestinal bleeding and sepsis. He had a history of purulent pericarditis 18 months earlier. He also presented with atrial fibrillation associated with a cerebral transient ischemic accident two months earlier. A contrast computed tomography scan showed an atrio-esophageal fistula with ...
BACKGROUND Radiofrequency ablation for atrial fibrillation is becoming widely practiced. METHODS AND RESULTS Two patients undergoing circumferential pulmonary vein ablation for atrial fibrillation in different centers developed symptoms compatible with endocarditis 3 to 5 days after the procedure. Their clinical condition deteriorated rapidly, and both suffered multiple gaseous and/or septic ...
