Cardiac hemodynamics immediately following aortic valve surgery

Aortic valve replacement following previous coronary surgery.

Aortic valve replacement following previous coronary surgery is associated with high risk. Major intraoperative problems include those associated with reentry, damage to the left internal mammary artery and myocardial protection. These factors influence operative results and eventual outcome to a large extent. The available evidence largely consists of retrospective series and case reports, wit...

Hemodynamics of aortic valve atresia.

Hemodynamic data on 12 infants with aortic valve atresia, ranging from 1 to 3 mo of age, are presented. Peripheral arterial oxygen saturations ranged from 19 to 93%. The lowest saturations were found in patients with closed foramen ovales. Increasing age, increasing pulmonary vascular resistance, and a decrease in the pulmonary-to-systemic blood flow ratio all correlated with decreasing systemi...

Aortic root pseudoaneurysm following surgery for aortic valve endocarditis.

Prosthetic aortic valve replacement for aortic valve endocarditis remains a primary practice of most cardiac surgeons. Usually it cures endocarditis and restores cardiac function. However, in advanced aortic valve endocarditis with complex annular destruction, complications following prosthetic aortic valve replacement do occur and present a formidable challenge for reoperation. Herein, we desc...

Minimally Invasive Cardiac Surgery: A Safe Alternative for Aortic Valve

Over the past 50 years, surgical aortic valve replacement with cardiopulmonary bypass has been the most widely employed strategy for the treatment of symptomatic aortic stenosis. Advances in prosthetic technology have contributed to improvements both in valve design and in the techniques used in surgical implantation. More recently, minimally invasive surgery for aortic valve replacement has un...
