Short-term outcomes of rotational atherectomy in patients with reduced left ventricular ejection fraction: A retrospective review from a tertiary referral centre.
Article in Indian heart journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveRotational atherectomy (RA), a commonly used technique for the percutaneous intervention of calcific coronary lesions, produces micro-debris which cause downstream microvascular obstruction, slow flow, and myocardial stunning leading to adverse outcomes in patients with left ventricular (LV) systolic dysfunction. Hence, the presence of LV dysfunction was considered a relative contraindication for RA. We aimed to assess the safety of RA in patients with LV dysfunction.
methodThis is a retrospective review of all consecutive patients who underwent RA at our tertiary referral centre over a 6-year period (2018-2023). All medical records, procedural details, and in-hospital outcomes were recorded. The primary outcome of the study was in-hospital mortality.
results504 patients who underwent RA during the study duration were divided into two groups: Group 1 (n = 209) with left ventricular ejection fraction (LVEF) ≤35 % (mean 29.14 ± 4.95 %) and group 2 (n = 295) with moderately reduced or preserved LVEF >35 % (mean 47.86 ± 6.68 %). There was no significant difference in the baseline demographic characteristics, risk factors, angiographic profile, stent length, contrast volume, and procedure time between the two groups. The in-hospital mortality was not different between the two groups (2.3 % vs 0.7 % p = 0.63). LVEF was not found to be an independent predictor of mortality in patients undergoing RA.
conclusionThe in-hospital mortality of patients undergoing PCI with RA was not affected by the presence of LV dysfunction. Additional studies with a longer follow-up duration and a larger sample or a meta-analysis incorporating our study are needed to confirm these results.
