Left Ventricular Apical Cannulation in Acute Type A Aortic Dissection.
Review in Journal of cardiovascular development and disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
objectivesIn cases of acute type A aortic dissection, including iatrogenic cases following transcatheter procedures, the choice of arterial cannulation site has a critical influence on early haemodynamics, organ protection and the risk of malperfusion. Transapical left ventricular cannulation has been suggested as a 'central' approach for rapidly establishing cardiopulmonary bypass with antegrade true-lumen flow. This review summarises the current evidence on TAC in acute type A dissection, focusing on indications, technical aspects and clinical outcomes. MATERIALS AND
methodsWe conducted a narrative review of observational studies and technical reports describing TAC for the surgical repair of acute type A aortic dissection. Particular attention was paid to patient selection, operative technique, perioperative complications, and early and mid-term results.
resultsAcross the published series, TAC is primarily employed in haemodynamically unstable patients or when the peripheral arteries are dissected, diseased, or unsuitable. A long arterial cannula is introduced through the left ventricular apex, crosses the aortic valve and is positioned in the true lumen of the ascending aorta under echocardiographic guidance. This configuration enables the rapid initiation of CPB, shortens skin-to-pump times, and provides reliable antegrade inflow. Early mortality and stroke rates are comparable to those associated with other cannulation strategies. Reported complications include malperfusion requiring site conversion, apical bleeding and rare local structural damage. These can be minimised through standardised technique and systematic imaging.
conclusionsTAC is a valuable bail-out option and, in selected patients, a primary cannulation option for acute type A aortic dissection when conventional arterial access is unsafe or ineffective. Although it offers fast and reproducible establishment of antegrade true-lumen flow, it requires specific expertise in apical exposure and intraoperative echocardiography. It should therefore be integrated into a structured perfusion and repair strategy.
