Background: Since May 1992 the Medtronic Open Pivot mechanical heart valve has been implanted routinely at the authors' institution. The study aim was to analyze, retrospectively, the 20-year clinical results of the valve.
Methods: Between May 1992 and December 2011 a total of 1,520 valves was inserted into 1,382 consecutive patients (1,012 aortic, 473 mitral, 26 tricuspid, 9 pulmonary).

Objectives: We studied a contemporary cohort of adult patients treated surgically for infective endocarditis (IE) in order to evaluate the surgical approach and predictors of outcomes, in relation to the intercurrent adaptation of the 2006 ACC/AHA guidelines.
Methods: One hundred and eighty-six consecutive patients operated on for active IE from August 1999 to September 2012 were reviewed retrospectively. Clinical presentation, surgical management and outcomes in the two study periods before and after January 2007 were compared (Period 1: n = 95 and Period 2: n = 91).
Background: Secreted factors from epicardial adipose tissue (EAT) have been implicated in the development of cardiomyocyte dysfunction. This study aimed to assess whether alterations in the secretory profile of EAT in patients with type 2 diabetes mellitus (DM2) affect contractile function and insulin action in cardiomyocytes.
Methods And Results: Contractile function and insulin action were analyzed in primary adult rat cardiomyocytes incubated with conditioned media (CM) generated from explants of EAT biopsies obtained from patients without and with DM2.

Surgical placement of a left ventricular epicardial pacing lead is a valuable alternative to the standard approach of endovascular placement of a pacing lead in the coronary sinus for cardiac resynchronization therapy. Despite higher perioperative morbidity, surgically placed leads perform well with lower revision and dislocation rates. Moreover, surgery is the only option when an endovascular approach proves to be unsuccessful.

Objective: The authors conducted a systematic review and meta-analysis to estimate the predictive value of E2 for CVD, and to identify study features explaining conflicting results.
Data Sources: Articles were identified by a Medline and Embase search and citation tracking.
Background And Aim Of The Study: Since January 1990, a variety of mechanical valves (St. Jude Medical, CarboMedics, ATS Medical) have been implanted routinely at the authors' institution. The study aim was to analyze, retrospectively, the 20-year clinical results of those mechanical valves, and to challenge the anticoagulation policy employed over the years.

Methods: Between 1998 and 2008, 1406 consecutive patients were recorded in a prospective database. Based on the main clinical indication for IABP use, we defined 3 groups: group A, 630 cases of coronary ischaemia or infarction without serious left ventricular (LV) dysfunction; group B, 466 patients with left ventricular failure or cardiogenic shock; group C, 310 patients where IABP was used for miscellaneous procedures such as weaning from cardiopulmonary bypass or during high-risk angioplasty or surgery.
Aneurysm formation is a well-known complication of untreated long-standing dissection of the aorta. Despite numerous advances in cardiac surgery, intrinsic diseases of the ascending aorta and aortic arch requiring surgical therapy, remain a technical challenge. However, surgery is the only option for effective treatment of ascending aorta aneurysm but carries an increased risk of severe morbidity and mortality, particularly in the elderly.

Commonly, the left anterior descending artery is involved which results in an anterior myocardial infarction, diagnosed within a variable time span of 24 hours to 6 months.We report on an unusual case of left main stem occlusion in a young adult patient presenting with evolving angina 5 years after an apparently minor chest trauma.

The study aim was to analyze, retrospectively, the 15-year clinical results of these implanted ATS valves.
Methods: Between May 1992 and December 2005, a total of 1,160 ATS valves (749 aortic, 381 mitral, 21 tricuspid, nine pulmonary) was implanted in 1,047 consecutive patients (655 males, 392 females; mean age 62.
Objective: Based on the adverse relationship between left ventricular (LV) remodeling and clinical outcome in ischemic cardiomyopathy, surgical ventricular restoration (SVR) is proposed as a valuable adjunct procedure. This study reports on the short-term clinical and hemodynamical performance of SVR.
Methods: Using end-systolic LV volume as indication for SVR, 78 patients with ischemic cardiomyopathy are divided in two groups: group 1 comprised 55 patients treated by coronary revascularization and mitral annuloplasty, group 2 comprised 23 patients undergoing additional SVR.
Background: The arterial switch operation is the preferred treatment for transposition of the great arteries (TGA), but there are concerns on the fate of the neoarterial trunks.
Methods: Ninety-three children were reviewed for functional and morphologic assessment of both reconstructed arteries after the arterial switch operation. Longitudinal analysis focused on neoaortic valve function, neoaortic obstruction, and neopulmonary stenosis as well as on the time-related size changes of both roots, with its clinical implications.
