Subintimal bailout recanalization for acute stent-jailed side branch occlusion: a single-center retrospective case series with QFR assessment.
Article in BMC cardiovascular disorders, 2026. 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
backgroundAcute side branch (SB) occlusion after main vessel (MV) stenting remains a challenging complication of bifurcation PCI, particularly when conventional true-lumen rewiring attempts fail. In such scenarios, operators face limited standardized bailout options, and guidance on decision-making is scarce.
methodsWe retrospectively analyzed a highly selected single-center case series of patients with acute stent-jailed SB occlusion refractory to conventional rewiring who underwent chronic total occlusion (CTO)-derived subintimal bailout recanalization. A predefined technical framework was applied. Angiographic results were assessed using Thrombolysis in Myocardial Infarction(TIMI) flow, and angiography-derived quantitative flow ratio (QFR) was used as physiological confirmation of reperfusion.
resultsAmong 9,832 PCI procedures performed between 2019 and 2023, 15 consecutive patients met the inclusion criteria. Subintimal SB recanalization was achieved in all cases, resulting in restoration of TIMI 3 flow. Postprocedural SB QFR was successfully obtained in all patients, with a mean value of 0.91 ± 0.04; all exceeded the predefined ischemic threshold (QFR ≥ 0.80). No procedure-related perforation, tamponade, or device entrapment was observed. Limited follow-up angiography and QFR data, available in two patients, demonstrated stable or improved functional values.
conclusionsIn a highly selected case series managed at an experienced center, a structured subintimal bailout framework appears feasible for the treatment of acute stent-jailed SB occlusion when conventional rewiring fails. Integration of QFR provides objective physiological confirmation of SB reperfusion and may assist in procedural decision-making. These findings should be considered hypothesis-generating and warrant validation in larger, prospective studies.
