| Abstract |
In patients with advanced heart failure, morbid obesity is a relative contraindication to heart transplantation due to higher morbidity and mortality in these patients. We performed a retrospective analysis of consecutive morbidly obese patients with advanced heart failure who underwent bariatric surgery for durable weight loss in order to meet eligibility criteria for cardiac transplantation. Seven patients (4 M/3 F, age range 31-56 years) with left ventricular ejection fraction (LVEF) ≤25 % underwent laparoscopic bariatric surgery. Median preoperative body mass index (BMI) was 42.8 kg/m(2) (range 37.5-50.8). There were no major perioperative complications in six of seven patients. Median length of hospital stay was 5 days. There was no mortality recorded during complete patient follow-up. At a median follow-up of 406 days, median BMI reduction was 12.9 kg/m(2) (p = 0.017). Postoperative LVEF improved to a median of 30 % (interquartile range (IQR) 25-53 %; p = 0.039). Two patients underwent successful cardiac transplantation. Two patients reported symptomatic improvement with little change in LV function and now successfully meet listing criteria. Three patients showed marked improvement of their LVEF and functional status, thus removing the requirement for transplantation. Bariatric surgery can achieve successful weight loss in morbidly obese patients with advanced cardiac failure, enabling successful heart transplantation. In some patients, cardiac transplantation can be avoided through surgical weight loss. |

Attention Score in Context
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 05 August 2019.
All research outputs
#14,839,922
of 22,852,911 outputs
Outputs from Obesity Surgery
#1,973
of 3,374 outputs
Outputs of similar age
#144,687
of 262,654 outputs
Outputs of similar age from Obesity Surgery
#19
of 57 outputs
Altmetric has tracked 22,852,911 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,374 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one is in the 39th percentile – i.e., 39% 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 262,654 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 57 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 63% of its contemporaries.
