Randomized Controlled TrialOverestimation of screening-related complications in the National Lung Screening Trial.
Lung cancer screening-associated complications are often quoted as one of the major barriers for wider screening adoption. A detailed analysis of the National Lung Screening Trial dataset was performed to extrapolate the safety of lung cancer screening. ⋯ It is more informative to report procedural complications in patients not found to have cancer as the true screening-associated risk. Only 4 in 10,000 of patients undergoing low-dose computed tomography screening but not found to have lung cancer will have major complications. Permanent or debilitating complications are exceedingly rare.

ReviewPreoperative left ventricular longitudinal strain predicts outcome of septal myectomy for obstructive hypertrophic cardiomyopathy.
The objective of this study was to determine the characteristics of longitudinal strain and its effect on outcomes in patients with obstructive hypertrophic cardiomyopathy (HCM) who underwent septal myectomy. ⋯ Left ventricular longitudinal strain is nonuniform and might be significantly reduced in patients with obstructive HCM. Septal myectomy does not impair GLS but is associated with more uniform regional strains. Most importantly, reduced GLS preoperatively is strongly and independently associated with increased all-cause mortality after septal myectomy for obstructive HCM.

Additional survival benefit of bilateral in situ internal thoracic artery grafting with composite radial artery graft in total arterial off-pump coronary artery bypass grafting.
This study aimed to elucidate whether the use of bilateral internal thoracic arteries (BITAs) confers additional survival benefits compared with a single internal thoracic artery (SITA) in total arterial grafting with the radial artery. ⋯ BITA grafting with the radial artery provides better long-term survival than SITA grafting with the radial artery, which is enhanced among patients aged <77 years with minimum comorbidities.

Long-term outcomes after aortic root repair using selective sinus replacement.
The study aim was to evaluate long-term results after anatomic restoration of the aortic root. ⋯ Patient-tailored root repair using isolated sinus replacement offers excellent functional long-term results regardless of underlying root pathology or annulus size. Aortic cusp pathology was decisive for long-term valve function.
