Review Comparative Study
Minimally Invasive Aortic Valve Replacement: Cost-Benefit Analysis of Ministernotomy Versus Minithoracotomy Approach.
Minimally invasive aortic valve replacement via ministernotomy (ministernotomy-AVR) or minithoracotomy (minithoracotomy-AVR) is gaining popularity. To date, a direct comparison of ministernotomy-AVR versus minithoracotomy-AVR is lacking. The study aim was to compare these two procedures from a cost-benefit perspective. ⋯ The present analysis suggested that the clinical benefits of ministernotomy-AVR are comparable or better than those of minithoracotomy-AVR, and at lower costs. Healthcare delivery organizations should consider the results of cost-benefit examinations when developing surgical valve replacement programs.

Review Case Reports
Takotsubo cardiomyopathy after minimally invasive mitral valve surgery: clinical case and review.
A sudden, unexpected, reversible, severe left ventricular dysfunction, mimicking an acute myocardial infarction without demonstrable obstructive coronary artery stenosis, was first recognized in Japan in 1990 and originally termed takotsubo cardiomyopathy. In 2006, the American Heart Association included takotsubo cardiomyopathy into its classification of primary acquired cardiomyopathy. ⋯ The study aim was to investigate the association between the occurrence of takotsubo cardiomyopathy and emotional or physical stressors, as described also in the setting of various surgical procedures. The case is also described of a 77-year-old woman who suffered a transient left ventricular dysfunction soon after cardiac surgery for valvular disease and epicardial cryoablation of atrial fibrillation.

Heyde's syndrome is an uncommon association between aortic stenosis and gastrointestinal bleeding. Although initially described during the late 1950s, with subsequent reports of a possible link between these disorders, controversy persists regarding the incidence, pathogenesis, and treatment of this syndrome. ⋯ A variety of treatment modalities of the syndrome has been applied, including medical management, endoscopic therapy, embolization, and aortic valve replacement. Here, the controversies surrounding Heyde's syndrome, which focus on pathogenesis and treatment, are reviewed with the aim of providing a clearer understanding of the syndrome and the implications for patient care.

Real-time three-dimensional transesophageal echocardiography (RT-3D-TEE) represents a unique perioperative cardiovascular imaging tool which, without any need for off-line reconstruction, has been shown to be highly valuable for evaluating mitral valve and other intracardiac structures. It is highly probable that, in the near future, RT-3D-TEE will have a positive effect on the perioperative assessment of complex 3D mitral valve structures, as it provides important approaches to the pathophysiology of various mitral valve diseases, including prosthetic valves, and will become incorporated into everyday perioperative practice. The clinical applications and therapeutic implications of perioperative RT-3D-TEE in the thorough assessment of the mitral valve are briefly summarized in this review.

In recent years, there has been a revival in the use of bioprosthetic valves as aortic substitutes. For example, during 2008 in Germany, among 12,397 patients who underwent isolated aortic valve procedures, 78% received a biological prosthesis and 21% a mechanical valve, while only 1% underwent valve repair. However, whilst this situation is the reverse of that during the 1990s, the question must be asked as to whether this is simply a fluctuating fashion, or a reflection of other factors.
