Comparative StudyIs surgery the gold standard in the treatment of obstructive hypertrophic cardiomyopathy?
Hypertrophic cardiomyopathy is a complex and relatively common genetic cardiac disease and has been the subject of intensive scrutiny and investigation for over 40 years. The aim of this non-randomized cohort study was to compare subjective and objective outcomes in hypertrophic cardiomyopathy patients undergoing drug therapy, surgical myotomy-myectomy, dual-chamber pacing and alcohol septal ablation. ⋯ Surgical myectomy, dual-chamber pacing and alcohol septal ablation are equally effective in reducing obstruction in case of correct indications. Dual-chamber pacing is indicated in functional reversible states characterized by excitation delay. Alcohol septal ablation is preferable in cases with midventricular obstruction and appropriate coronary anatomy. Surgical methods are indicated in anatomical irreversible changes and remain the gold standard for obstructive hypertrophic cardiomyopathy treatment.

ReviewCan pregnant women be safely placed on cardiopulmonary bypass?
A best evidence topic was written according to a structured protocol. The question addressed was whether cardiopulmonary bypass can be used safely with satisfactory maternal and foetal outcomes in pregnant patients undergoing cardiac surgery. A total of 679 papers were found using the reported searches of which 14 represented the best evidence to answer the clinical question. ⋯ There were no reports of maternal mortality and one report of foetal mortality. Mean cardiopulmonary bypass and aortic cross-clamp times were 105 and 50 min, respectively. We conclude that while the use of cardiopulmonary bypass during pregnancy poses a high risk for both the mother and the foetus, the use of high-flow, high-pressure, pulsatile, normothermic bypass and continuous foetal and uterine monitoring can allow cardiac surgery with the use of cardiopulmonary bypass to be performed with the greatest control of risk in the pregnant patient.

ReviewDo endobronchial valves improve outcomes in patients with emphysema?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether endobronchial valves improve outcomes in patients with severe emphysema. Eighty-seven papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. ⋯ This evidence is reflected in the Endobronchial Valve for Emphysema Palliation Trial. Patients treated with endobronchial valve with high heterogeneity and complete fissures had greater improvement in forced expiratory volume in one second at 6- and 12-month intervals. We conclude that endobronchial valve placement improves lung function, exercise capacity and quality of life in selected patients with emphysematous diseases.

ReviewIs totally endoscopic coronary artery bypass safe, feasible and effective?
A best evidence topic was written according to a structured protocol. The question addressed was whether totally endoscopic coronary artery bypass (TECAB) is safe, effective and feasible. A total of 171 papers were found, of which eight represented the best evidence. ⋯ In conclusion, TECAB represents a feasible alternative to conventional coronary artery bypass in selected patients. It is associated with low morbidity and excellent mid-term graft patency. Larger, prospective and multicentre trials are required to assess the long-term and patient-reported outcomes of TECAB.
