Abstract

The prognostic value of echocardiographic apical 4 chamber recordings was assessed retrospectively in 18 patients who underwent left ventricular aneurysmectomy following anterior wall myocardial infarction. After an average follow-up period of 2 years, 7 patients had died or remained in functional Classes III or IV (Group 1) and 11 patients had satisfactory clinical outcomes (Group 2). There were no significant clinical or coronary angiographic differences between the two groups. The left ventricular surface area, transverse diameter and fractional shortening of the surface were also comparable in the two groups. The surface area of the aneurysm was greater in patients in Group 1 (37.4 +/- 11.8 cm2 vs 21.1 +/- 15.8 cm2, p less than 0.05). However, the more discriminating parameters were those related to the non-aneurysmal contractile zones (NACZ). Patients in Group 1 had a smaller relative surface area of the NACZ than those in group 2; 6 of the 7 patients in Group 1 had NACZ of less than 40 per cent of the left ventricle compared with none of the patients in Group 2 (p less than 0.001). In addition, the function of the NACZ was significantly worse in Group 1: surface fractional shortening: 9.6 +/- 10.2% vs 32.6 +/- 8.3% (p les...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

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.
