Sublobar resections in stage IA non-small cell lung cancer: segmentectomies result in significantly better cancer-related survival than wedge resections.
Sublobar resections spare pulmonary function and offer a method of increasing resection rates in patients with lung cancer and limited functional operability. Previous studies demonstrated an increased local recurrence rate following wedge resections compared to segmentectomies in stage IA non-small cell lung cancer (NSCLC). However, a prognostic impact of this observation has never been shown and is still under debate. Therefore, this study has been performed to analyse the cancer-related survival of sublobar resections in stage IA patients. ⋯ Studies investigating survival after sublobar resection of stage IA NSCLC should always distinguish between anatomical segmentectomies and wedge resections. If limited functional operability requires a sublobar resection of stage IA NSCLC, segmentectomy with systematic lymphadenectomy should be preferred.

Comparative StudyModerate versus deep hypothermia for the arterial switch operation--experience with 100 consecutive patients.
To evaluate the impact of moderate versus deep perioperative hypothermia on postoperative morbidity in patients receiving the arterial switch operation (ASO). ⋯ The ASO under full-flow moderate compared to deep hypothermia was advantageous regarding length of procedure and primary chest closure rate. Moderate hypothermia seemed to be beneficial for pulmonary recovery, length of chest tube drainage treatment and inotropic support. No worse early or long-term effects of moderate hypothermia were found.

Evolution of tricuspid regurgitation after mitral valve repair for functional mitral regurgitation in dilated cardiomyopathy.
To assess the evolution of tricuspid regurgitation (TR) in dilated cardiomyopathy (DCM) patients submitted to mitral repair for functional mitral regurgitation (MR). ⋯ A significant number of patients submitted to mitral repair for functional MR present > or =3+ TR at follow-up as consequence of progression of untreated TR or failure of tricuspid repair. A more aggressive and effective treatment of functional TR in this setting should be pursued.

First clinical experience and 1-year follow-up with the sutureless 3F-Enable aortic valve prosthesis.
Aortic valve replacement (AVR) with extracorporeal circulation (ECC) is currently the treatment of choice for symptomatic aortic stenosis. However, patients with multiple high-risk comorbid conditions may benefit from reduced ECC time and thus, reduced myocardial ischemia, by the use of sutureless AVR. We describe the initial experience and 1-year results of our first 3F-Enable AVR implants. ⋯ These first 1-year follow-up data suggest the feasibility of this new concept of sutureless aortic valve implantation. However, severe aortic insufficiency at 8 months and paravalvular leakage at 1-year follow-up should prompt further procedural and device enhancements.

Transcranial motor-evoked potentials following intra-aortic cold blood infusion facilitates detection of critical supplying artery of spinal cord.
In order to determine whether critical intercostal artery is present in the aneurysm during descending thoracic or thoracoabdominal aortic surgery, changes of transcranial motor-evoked potentials (Tc-MEPs) were monitored following infusion of cold blood into the aorta as an adjunct 'on-site assessment'. Accuracy of this method was evaluated. ⋯ Cold blood infusion into the clamped segment of aorta accelerates Tc-MEPs changes and can possibly reduce ischemic insults of spinal cord during diagnostic process, while it accurately detects presence of critical intercostal artery in the segment. This method appears to be promising adjunct on-site assessment.
