A succinct analysis of a challenging problem, with a discussion on the 'magic diameter' of 55 mm.
This single institution study of outcomes for the treatment of supravalvular aortic stenosis over a 20-year period identified risk factors for reintervention or reoperation: age <1 year, smaller aortic valve or aortic root, and concomitant right ventricular outflow tract repair.
Aortic annulus size and shape were analyzed in computed tomography angiography after a reimplantation procedure in patients with bicuspid and tricuspid aortic valves. Prior to surgery, elliptic shape was observed in tricuspid valves and more circular shape in bicuspid valves. After reimplantation, there was no difference between groups with similar roundness regardless of valve morphology. The authors concluded that annuloplasty plays an active role on the geometry of the aortic annulus.
This single institution study spanning a decade of experience identified a 6.5% rate of mortality, which was related to active endocarditis at the time of surgery, the need for preoperative ventilation, longer bypass times, and increasing European risk score.
Interesting retrospective imaging study of true and false lumens with or without bare metal stents placed distally in the abdominal aorta.
This brief overview of recently presented improvements in lung cancer therapy highlights the substantial benefits of newer chemotherapy and immunotherapy regimens that are transforming the outlooks of many patients with advanced lung cancer.
Data from the PARTNER trials were assessed regarding post-procedural prosthetic valve endocarditis (PVE) after transcatheter aortic valve replacement and surgical aortic valve replacement. The timing and rates of PVE were similar between the groups, and they had a similar high mortality.
In this randomized trial, percutaneous coronary intervention and CABG had equivalent outcomes for the composite of death, stroke, or myocardial infarction at five years for patients with left main disease of low or intermediate anatomical complexity.
Gudala and associates performed a literature review of 108 patients who sustained left ventricular rupture following mitral valve replacement. The incidence in pooled data was 0.72%. The authors expounded on the mechanisms, classification, repair techniques, and treatment outcomes of this dreadful complication. In addtion, they added a subcategory, type IV, and proposed an alternative surgical classification. This is a thorough and comprehensive review that would be helpful to all cardiac surgeons.
Participation in a post-discharge rehabilitation program after valve surgery was associated with a 34% relative decrease in hospitalization during the first year and a 61% relative decrease in mortality at one year.
