Ascending aortic dilatation as a late complication after implantation of a mechanical aortic valve performed 37 years earlier.

Aortic stenosis (AS) is the third most common cardiovascular disease. Aortic valve replacement (AVR) is the only effective method of treatment in most AS patients. In some patients, AS leads to poststenotic dilatation of the ascending aorta - most commonly, this occurs in patients with concurrent aortic regurgitation or bicuspid aortic valve (BAV) and in patients after aortic valve replacement. Cardiac surgeons face the dilemma whether to perform concurrent replacement of the dilated ascending aorta in patients qualified for AVR, as it is associated with an increased risk of perioperative complications and mortality. We report a case of a patient with an ascending aortic aneurysm, who had been implanted with an aortic mechanical valve (Lillehei-Kaster 16 ECC) 37 years earlier.

A congenital complex including muscular interventricular septal aneurysm in an adult: case report and review of literature.

Muscular interventricular septum is an extremely rare location for congenital aneurysm. A 48-year-old patient with a muscular interventricular septum aneurysm coexisting with atrial septal defect, pulmonary stenosis and ventricular preexcitation is presented. Three-dimensional echocardiographic reconstruction of the lesion aided in a precise morphologic and quantitative assessment of the condition. The review of 10 previously reported patients with the entity is presented.
