A 55-year-old man with a history of erosive, seropositive rheumatoid arthritis (RA), and interstitial lung disease presented with shortness of breath. Echocardiography showed new-onset severe left ventricular (LV) dysfunction with an ejection fraction (EF) of 15% and moderately increased mean aortic valve gradient of 20 mmHg in a trileaflet aortic valve with severe sclero-calcific degeneration. Coronary angiography revealed no significant obstructive coronary disease. Invasive hemodynamic studies and dobutamine stress echocardiography were consistent with moderate aortic stenosis...

Accurate evaluation of trans-aortic valvular pressure gradients is challenging in cases where dual mechanical aortic and mitral valve prostheses are present. Non-invasive Doppler echocardiographic imaging has its limitations due to multiple geometric assumptions. Invasive measurement of trans-valvular gradients with cardiac catheterization can provide further information in patients with two mechanical valves, where simultaneous pressure measurements in the left ventricle and ascending aorta must be obtained...

BACKGROUND: We aimed to determine the relationship between hospital volume and use of dual aortic and mitral valve surgical procedures. METHODS: Patients who underwent both aortic and mitral valve repair or replacement during the same hospital stay were identified from the Nationwide Inpatient Sample (NIS). We compared patients' characteristics and in-hospital outcomes by the average annual center volume for multiple-heart valve surgical procedures, grouped into tertiles of patients with low (1 to 8), medium (9 to 18), and high (19+) volume categories using χ(2) tests and adjusted hierarchical logistic regression models...

Atherosclerosis and valvular heart disease often require treatment with corrective surgery to prevent future myocardial infarction, ischemic heart disease, and heart failure. Mechanisms underlying the development of the associated complications of surgery are multifactorial and have been linked to inflammation and oxidative stress, classically as measured in the blood or plasma of patients. Postoperative pericardial fluid (PO-PCF) has not been investigated in depth with respect to the potential to induce oxidative stress...

There are very few studies on valvular heart disease in women. There is a sex influence in the prevalence of some types of valve disease: it is well known that rheumatic mitral stenosis is very common in women but degenerative valve disease affects both sexes in a similar way. In degenerative aortic stenosis several physiopathological differences have been reported in women: the amount of calcium is lower than in men and the left ventricle generates higher gradients and hypercontractile response in women. Regarding prognosis it is well accepted that women have higher mortality rates than men in cardiac surgery, both in coronary surgery and in valvular surgery...

BACKGROUND: Cardiac surgery with cardiopulmonary bypass is associated with mechanical manipulation of the ascending aorta that occasionally leads to type A aortic dissection (AAD). METHODS AND RESULTS: One hundred three patients with surgical repair for AAD following nonaortic cardiac surgery were identified. With the use of logistic regression modeling, coronary artery bypass surgery (CABG), either isolated or combined with another procedure in the initial operation, was associated with significantly higher operative mortality in comparison with patients with non-CABG procedures at the time of AAD repair both for all patients (odds ratio, 2...

OBJECTIVES: To determine rate of reoperation subsequent to primary valve repair in a pediatric population. METHODS: Between 1996 and 2009, 142 consecutive patients underwent aortic valve repair in our institution. Median age at surgery was 9 years, with 30 being younger than age 1 year. Indication for surgery was stenosis (n = 76), regurgitation (n = 55), and both (n = 11). Forty-six patients underwent repair with no addition of patch, whereas 96 patients required addition of patches of glutaraldehyde preserved autologous pericardium for cusp extension (n = 51) and other repair (n = 45)...

BACKGROUND: Coarctation of the aorta with cardiac lesions or complex coarctation is a formidable challenge for cardiac surgeons. Extra-anatomic bypass allows simultaneous intracardiac repair or an alternative approach for patients with complex coarctation. METHODS: Between July 1997 and March 2008, 43 patients with coarctation of the aorta underwent extra-anatomic bypass grafting, including 10 ascending-to-descending aorta bypasses and 33 ascending aorta-to-infrarenal abdominal aorta bypasses...

BACKGROUND: Low cardiac output syndrome is defined as the need for a postoperative intra-aortic balloon pump or inotropic support for longer than 30 minutes in the intensive care unit. Mitral valve surgery is increasingly being performed in high-risk patients who might require mechanical circulatory support for low cardiac output syndrome. Therefore the aim of this study was to identify the preoperative predictors of low cardiac output syndrome after mitral valve surgery. METHODS: We conducted a retrospective review of data prospectively entered into an institutional database...

Recent technical improvements have allowed to non-invasive cardiac imaging by Multidetector CT. (MDCT). In initial work we compared the value of successive generations of MDCT (4, 16, and 64 slice) for non-invasive imaging of coronary arteries vs. non-invasive magnetic resonance coronary angiography using conventional coronary angiography as gold standard. Our work demonstrated progressive improvement of diagnostic accuracy from 4 to 64 slice MDCT technology. The most recent generation of 64 slice MDCT became more performing than MRI...

Due to improved outcome after surgery for congenital heart defects, children, adolescents, and grown-ups with congenital heart defects become an increasing population. In order to evaluate operative risk and early outcome after mechanical aortic valve replacement (AVR) in this population, we reviewed patients who underwent previous repair of congenital heart defects. Between July 2002 and November 2008, 15 (10 male and 5 female) consecutive patients (mean age 14.5 +/- 10.5 years) underwent mechanical AVR. Hemodynamic indications for AVR were aortic stenosis in four (27%), aortic insufficiency in eight (53%), and mixed disease in three (20%) after previous repair of congenital heart defects...
