Bridge to durable left ventricular assist device for refractory cardiogenic shock.
The role of short-term mechanical circulatory support has increased in patients with refractory cardiogenic shock. However, limited data exist on the outcomes of a bridge to a durable left ventricular assist device strategy using short-term mechanical circulatory support. ⋯ Short-term mechanical circulatory support can optimize patients in refractory cardiogenic shock and serve as a bridge to implantation of a durable left ventricular assist device. However, the early mortality rate after durable left ventricular assist device implantation is high because of unrecognized right ventricular failure.

A risk score to predict the incidence of prolonged air leak after video-assisted thoracoscopic lobectomy: An analysis from the European Society of Thoracic Surgeons database.
The study objective was to develop an aggregate risk score for predicting the occurrence of prolonged air leak after video-assisted thoracoscopic lobectomy from patients registered in the European Society of Thoracic Surgeons database. ⋯ An aggregate risk score was created to stratify the incidence of prolonged air leak after video-assisted thoracoscopic lobectomy. The score can be used for patient counseling and to identify those patients who can benefit from additional intraoperative preventative measures.

Obtaining the biomechanical behavior of ascending aortic aneurysm via the use of novel speckle tracking echocardiography.
Ex vivo measurement of ascending aortic biomechanical properties may help understand the risk for rupture or dissection of dilated ascending aortas. A validated in vivo method that can predict aortic biomechanics does not exist. Speckle tracking transesophageal echocardiography (TEE) has been used to measure ventricular stiffness; we sought to determine whether speckle TEE could be adapted to estimate aortic stiffness in vivo and compare these findings with those obtained by ex vivo tissue measurements. ⋯ The use of speckle TEE appears to be a promising technique to estimate ex vivo mechanical properties of the ascending aortic tissue.

Right ventricular dysfunction affects survival after surgical left ventricular restoration.
Several clinical and left ventricular parameters have been associated with prognosis after surgical left ventricular restoration in patients with ischemic heart failure. The aim of this study was to determine the prognostic value of right ventricular function. ⋯ Baseline right ventricular systolic dysfunction is independently associated with increased mortality in patients with ischemic heart failure undergoing surgical left ventricular restoration.

Surgery for predominant lesion in nonlocalized bronchiectasis.
Patients with nonlocalized bronchiectasis are encountered commonly; however, there is little information regarding surgical intervention in this patient population. The aim of this study was to evaluate symptomatic response and safety of anatomic resection of the predominant lesion via the use of lobectomy for the management of nonlocalized bronchiectasis. ⋯ Lobectomy for the predominant lesion is a safe procedure in the surgical treatment of nonlocalized bronchiectasis and leads to significant relief of symptoms with good rates of satisfaction.
