ReviewIs robotic mitral valve surgery more expensive than its conventional counterpart?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'Is robotic mitral valve surgery more expensive than its conventional counterpart?' Altogether 19 papers were found using the reported search, of which 5 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. ⋯ The fifth study was a large national database inquiry in which robotic approach was found to be more expensive by US$600 per case excluding amortization cost and by US$3700 if amortization is included. We conclude that the total hospital cost of robotic mitral valve surgery is slightly higher than conventional sternotomy surgery. If amortization is taken into consideration, robotic cases are considerably more expensive.

A new tissue-engineered biodegradable surgical patch for high-pressure systems †.
Ideal alternatives for replacing native arteries, which have biocompatibility such as growth potential, anti-thrombogenesis and durability, have yet to be discovered. We previously demonstrated the utility of tissue-engineered vascular autografts; however, the use of these autografts is limited to low-pressure conditions. The aim of this study was to create the tissue-engineered arterial patch (TEAP) that could be used in high-pressure systems, and to evaluate the maturation in this regenerative tissue. ⋯ We demonstrated the maturation of endothelial and smooth muscle cells in TEAP, suggesting that this biodegradable polymer scaffold could be used as an alternative vascular material even in high-pressure systems.

Extracorporeal life support in patients with refractory cardiogenic shock: keep them awake.
Traditionally, patients on extracorporeal life support (ECLS) are sedated and mechanically ventilated and therefore prone to complications related to immobility and ventilation. We adopted this 'Awake ECLS' strategy for the patients with refractory cardiogenic shock (RCS) as a bridge to decision. ⋯ ECLS as a bridge to decision in RCS is effective in restoring adequate systemic perfusion and recovering end-organ function. ECLS can be initiated in awake patients with RCS and patients can be awakened on ECLS. The 'awake ECLS' strategy may avoid complications related to mechanical ventilation, sedation and immobilization. RCS patients supported on ECLS without severe metabolic acidosis, multiorgan failure, intra-aortic balloon pump or uncertain neurological status are more likely to be weaned from the ventilator. Patients that are awake at the time of ECLS implantation are more likely to remain awake during ECLS.
