In this meta-analysis of five randomized trials comprising 958 patients, the authors study the effect of double versus single antiplatelet therapy on graft occlusion in patients undergoing coronary artery bypass graft surgery. Vein grafts in patients on double antiplatelet therapy were significantly less likely to occlude that those in patients on single therapy at up to 1-year follow up. This effect was not seen in arterial grafts. Safety data on bleeding was inconsistent.

This retrospective study from Vienna examined the correlation between length of extracted thrombi and outcomes after pulmonary endarterectomy in 110 pts.  The extent of thrombus extraction was inversely correlated with PVR.  PVR in the early postoperative period was the only predictor of survival and freedom from lung transplant.

This study used state-wide registries in 11 southern states to evaluate outcomes  of NSCLC treatment among black and white patients.  More blacks were diagnosed at later stages.  Survival for men was worse than for women, adjusted for covariates (HR 1.41).  Lung cancer mortality was similar for blacks and whites (HR 0.99).

This Ontario-based collaboration used meta-analyses of data from prospective trials to outline CT screening recommendations for individuals at increased risk for lung cancer.  Most guidelines are in line with recommendations from the Lung Cancer Screening Study, but important deviations were identified and justified.

In this promising investigation, investigators found that C4d, a degradation product of complement activation, assessed in bronchoalveolar lavage and plasma, predicts the presence of lung cancer compared with non-cancer patients. They found a shorter survival in patients with high levels in the plasma.  Plasma C4d levels were reduced after surgical resections, which means C4d may be useful as a marker of recurrence after resection.

An instant guide to Valve in Valve procedures for clinicians

Quick, clear and concise information about heart valves and Valve in Valve therapy. A guide you wish you always had at your fingertips.


Valve in Valve app was developed as a collaboration between the technology company UBQO and Dr. Vinayak (Vinnie) Bapat, Consultant Cardiac Surgeon at St. Thomas' Hospital, London, UK.

Valve in Valve app provides information specific for a clinical scenario, quickly and simply. This will help in the planning of and performing a Valve in Valve case. The application navigates the user through important aspects of surgical and TAVI valve design, which are vital for a successful Valve in Valve procedure. The app logically steps through the possible combinations to give the user specific information needed to perform the procedure.

Success of a Valve in Valve procedure is based on correct identification of the surgical valve, choosing the correct size of the TAVI valve and its subsequent accurate placement. Surgical valves vary in appearance under fluoroscopy and also in their internal diameter. Similarly TAVI valves differ in their appearances and available sizes.

Knowledge about all the surgical valves that have been implanted in the last two decades is minimal but relevant to the Valve in Valve therapy. Users can now familiarise themselves with important design information about surgical and TAVI valves; they can also select the valve and find out which size of TAVI valve could be used and how it is best placed during a Valve in Valve procedure.

If the valve type is unknown, the App also guides the user through a series of steps where they can identify the surgical valve type and then use the information available for it.

The Valve In Valve app can be used to plan a case and confirm suitability for this procedure and reduces the need to trawl through vast amounts of literature to find information specific to the clinical scenario. The information is also available without the need for an internet connection and will enhance the users understanding of various aspects of this procedure. We hope this will result in improved results and better outcomes for patients.

Key features

- Design information for multiple types of surgical valve
- Sizing information for multiple types of surgical valve
- Real life and fluoroscopic images of all the surgical valves
- Design information about TAVI valve designs
- Sizing information for these TAVI valves
- Guides the user through a stepped process to help choose a specific valve, then the size and lastly the important dimensions to plan a Valve in Valve procedure
- Image based guidance for the ideal placement of a TAVI valve
- Video examples of actual placement of a TAVI valve
- Discusses important design considerations in detail to improve understanding of the Valve in Valve procedure

The STICH trial compares medical therapy to medical therapy + CABG for ischemic cardiomyopathy.  In this study of over 1,200 there were 462 deaths during a median f/u period of nearly 5 years.  CABG reduced the risk of sudden death and death due to pump failure; overall cardiovascular death was reduced by CABG but not significantly (p=0.09).  There was a substantial early increase in mortality in pts undergoing CABG; the protective effects of CABG were evident primarily after 2 years.

After developing a definition of futile care, intensivists were surveyed in 5 ICUs for a period of 3 months, during which 1136 pts were treated.  19% of patients were perceived as receiving futile or probably futile care.  Of those receiving what was perceived as futile care, the 6 month mortality rate was 85%, and the cost of treatment was $2.6 million.

This prospective study tracked viral infections and their outcomes in lung transplant patients 2008-2011 in a single institution.  Respiratory viruses were identified in 174 of 903 encounters, 34 via BAL.  Viral infection rates were 14% for non-emergency visits and 34% for emergency visits.  Most viral infections were associated with symptoms and with transient lung function loss.

This retrospective study from the US Veterans Affairs Surgical Quality Improvement Program evaluated the use of off-pump bypass over time for primary isolated CABG.  Peak use in 2003 was 24%, which then decreased and stabilized at 19%.  Conversion rates steadily declined to a stable rate of under 3.5%.  Mortality for on-pump and off-pump CABG has remained below 2% since 2006.
