Abstract

To report 2324 coronary stenosis interventions (Vineberg procedures [VbP], coronary artery bypass graft operations [CABG] and percutaneous transluminal coronary angioplasties [PTCA]), in 1711 patients of a Canadian military hospital between 1965 and 1995 and to report their evolution and interaction in a historical context. Retrospective examination of clinical and angiographic findings in hard records, collected from the beginning for long term follow-up and later embedded in a custom-designed computer database. Most were male, mean ages 43.2 and 43.3 years for first and second VbPs; 48.9 and 58.2 years for first and repeat CABGs; and 53.4 and 59.9 years for first and repeat PTCAs, respectively; 12% of all patients were 39 years old or younger at the first intervention. There were 160 VbPs, 1637 CABGs and 527 PTCAs. Of 1711 subjects, 74% had only one procedure, 15% had more than one of the same kind, and 11% had more than one of different kinds. Perioperative mortality for VbPs was 4.4%; for 'isolated' first CABGs it was 1.4% and 6.6% for reoperations, when other concurrent major cardiac procedures, excepting ventricular aneurysm repair, were excluded. It was 0.4% for PTCAs. Perioperative mortality for all 1761 'isolated' coro...Continue Reading

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
