Background-Age Ͼ90 years represents in many centers an absolute contraindication to cardiac surgery. Nonagenarians are a rapidly growing subset of the population posing an expanding clinical problem. To provide helpful information in regard to this complex decision, we analyzed the operative and 5-year results of coronary and valvular surgical procedures in these patients. Methods and Results-We retrospectively reviewed 127 patients aged Ն90 years who underwent cardiac surgery within our hospital group in the period 1998 to 2008. Kaplan-Meier and multiple logistic regression analyses were performed. A longer follow-up than most published studies and the largest series published thus far are presented. Mean age was 92 years (range, 90 to 103 years). Mean logistic EuroSCORE was 21.3Ϯ6.1. Sixty patients had valvular surgery (including 11 valve repairs), 49 patients had coronary artery bypass grafting, and 18 had valvular plus coronary artery bypass grafting surgery (55 left mammary artery grafts implanted). Forty-five patients (35.4%) were operated on nonelectively. Operative mortality was 13.4% (17 cases). Fifty-four patients (42.5%) had a complicated postoperative course. There were no statistically significant differences in the rate and type of complications between patient strata on the basis of type of surgery performed. Nonelective priority predicted a complicated postoperative course. Predictors of operative mortality were nonelective priority and previous myocardial infarction. Kaplan-Meier survival estimates at 5 years were comparable between patient groups on the basis of procedure performed. Conclusions-Although the rate of postoperative complications remains high, cardiac surgery in nonagenarians can achieve functional improvement at the price of considerable operative and follow-up mortality rates. Cardiac operations in these very elderly subjects are supported if appropriate selection is made and if the operation is performed earlier and electively. Our results should contribute to the development of guidelines for cardiac operations in nonagenarians.
Vasodilation is impaired in various conditions, such as hypercholesterolemia and tobacco use. We evaluated brachial artery flow-mediated vasodilation (FMD) after blood pressure (BP) cuff occlusion using high-resolution B-mode ultrasound in 20 alcoholics, without any coexisting conditions such as smoking, hypertension, or cholesterolemia, after a 3-month period of abstinence. They were compared with a control group of 20 alcohol-free healthy subjects. We measured the diameter of the brachial artery under baseline conditions, during reactive hyperemia (with increased flow causing endothelium-dependent dilatation), and after administration of sublingual glyceryl trinitrate (GTN), an endothelium-independent dilator. We performed an echocardiographic study (Esaote Au3) according to guidelines of the American Society of Echocardiography to assess left ventricular mass (LVM), wall thickness, systolic stress, and diastolic function changes. FMD (% diameter change) was significantly less in the alcoholic patients than in the controls (6.03 ؎ 3.67 v 13.7 ؎ 4.65; P < .05), whereas no difference was noted after GTN administration (13.7 ؎ 7.97 v 16.0 ؎ 5.12, P ؍ NS). Echocardiographic study showed no differences between the study group for LVM, wall thickness, and systolic stress; diastolic function expressed as E/A ratio inversion was significantly impaired. These data demonstrate an impairment of endothelial-dependent vasodilatation in chronic alcohol abusers, which may contribute to the excess prevalence of cardiovascular diseases in these individuals.

Objectives: To clarify whether the results of repair of a complex mitral lesion (Barlow valve) at the intermediate-term follow-up are independent of the mode of surgical access [minithoracotomy vs. median sternotomy (MS)]. Methods: In a prospective randomized study of mitral repair for Barlow disease using either a minimally invasive (MI) approach or MS, we achieved an average follow-up of 3 years (echocardiography, physical examination and quality of life). Mitral repair was achieved with polytetrafluoroethylene chordal implantation for both leaflets. Results: Both groups included 80 patients. Mechanical ventilation time and intensive care unit and hospital stay were shorter in the MI group (p = 0.01, p = 0.013 and p = 0.02, respectively). During the follow-up, 5 patients in each group (6.25%) displayed mild mitral regurgitation, while 2 patients in each group (2.5%) developed recurrent regurgitation graded as at least moderate/severe. The rate of mitral reoperation was 2.5% in the MI group and 1.25% in the MS group (p = 0.9). The overall follow-up mortality was 3.75% in both the MI and the MS groups. Conclusions: The 3-year results of repair of Barlow valves were satisfactory irrespective of the approach used to repair the valve. The advantages of MI surgery can be achieved in patients with mitral Barlow disease without concerns over the durability of repair.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
