Tuberculous constrictive pericarditis has been reported with myocardial and endocardial involvement in a case series.8 It has been suggested that tubercular insult to the heart may result in involvement of all three layers with varying severity and the hallmark of differentiation between constrictive and restrictive disease appears to be a diligent attempt at identification of a thickened pericardium.
Involvement can be classified as follows: (1) pericarditis, (2) myocarditis, (3) endocardial (valve) involvement, (4) conduction defects, (5) coronary arteritis, and (6) granulomatous aortitis (1).
EBR Systems said its WiSE Technology is the world's only wireless endocardial pacing system for cardiac resynchronization therapy.
Cardiac involvement (pericardial, myocardial, endocardial) is known in patients of Rheumatoid arthritis.
Other cardiac abnormalities were found in the others cases (1-34) including myocarditis, left ventricular dilation, aortic and mitral valve lesions and endocardial invagination.
In the DEEP study, the cardiac surgeon and electrophysiologist work as a team to perform a minimally invasive epicardial (outside the heart) surgical ablation and endocardial (inside the heart) catheter-based ablation.
