Different types of cannulation techniques are available for minimally invasive cardiac surgery. At our institution, we favor a femoral platform for most minimally invasive cardiac procedures. Here, we review our results utilizing this cannulation approach.
We retrospectively reviewed all minimally invasive valve surgeries that were performed at our institution between January 2009 and January 2015. Operative times, lengths of stay, postoperative complications, and mortality were analyzed.
We identified 2,645 consecutive patients. The mean age was 69.7 ± 12.77 years, and 1,412 patients (53.4%) were male. Three hundred fifty-eight patients (13.5%) had a history of cerebrovascular accident, 422 (16%) had previous heart surgery, and 276 (10.4%) had a history of peripheral vascular disease. The procedures performed were isolated aortic valve replacements (42.1%), isolated mitral valve operations (40.6%), tricuspid valve repairs (0.57%), double valve surgery (15%), triple valve surgery (0.3%), and ascending aortic aneurysm resection with and without circulatory arrest (5%). Femoral cannulation and central cannulation were utilized in 2,400 patients (90.7%) and 244 patients (9.3%), respectively. The median aortic cross-clamp time and cardiopulmonary bypass time were 81 minutes (interquartile range, 65 to 105) and 113 minutes (interquartile range, 92 to 142), respectively. The median postoperative hospital length of stay was 6 days (interquartile range, 5 to 9). There were 31 cerebrovascular accidents (1.17%), no aortic dissections, two compartment syndromes, two femoral arterial pseudoaneurysms, and 174 (6.65%) groin wound seromas. The overall 30-day mortality was 57 patients (2.15%).
Minimally invasive cardiac surgical procedures utilizing femoral cannulation techniques have a low risk of complications.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 December 2016.
All research outputs
#16,242,729
of 25,663,438 outputs
Outputs from The Annals of Thoracic Surgery
#5,873
of 8,342 outputs
Outputs of similar age
#244,294
of 424,330 outputs
Outputs of similar age from The Annals of Thoracic Surgery
#55
of 96 outputs
Altmetric has tracked 25,663,438 research outputs across all sources so far. This one is in the 34th percentile – i.e., 34% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,342 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one is in the 27th percentile – i.e., 27% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 424,330 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 96 others from the same source and published within six weeks on either side of this one. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
