Acute left main coronary occlusion after transcatheter aortic valve implantation: life-saving intervention using the snare technique-a case report.

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: Transcatheter aortic valve implantation (TAVI) has rapidly evolved and changed the field of structural cardiovascular intervention. Its advances lead to a marked reduction in the risk of complications and improved outcomes. However, TAVI is still associated with potential serious complications. Case summary: A 73-year-old man with severe aortic stenosis underwent TAVI using a 34-mm self-expanding aortic bioprosthesis. After valve deployment, the patient rapidly progressed to cardiac arrest. Acute left main occlusion, due to high valve implantation, was promptly recognized and advanced life support immediately initiated. Concomitantly, the valve was successfully retrieved toward the ascending aorta using the snare technique, resulting in immediate restoration of flow and successful cardiopulmonary resuscitation. Subsequently, a 29-mm balloon-expandable aortic bioprosthesis was uneventfully implanted. After TAVI, the patient had a remarkable clinical evolution and was discharged home at hospitalization day five without relevant electrocardiographic nor echocardiographic disturbances. At six-month follow-up, the patient remains asymptomatic and transthoracic echocardiography revealed a normofunctional aortic bioprosthesis with preserved left ventricular ejection fraction. Discussion: Acute coronary occlusion is a rare and life-threating complication of TAVI that may be prevented with accurate procedure planning. Pre-procedural computed tomography angiography is essential for a comprehensive patient evaluation, allowing appropriate valve selection, a key factor for successful management. Self-expandable valve retrieval with snare technique can be an appropriate strategy for the management of this complication. This case highlights the importance of performing these procedures in highly experienced centres and with fully equipped catheterization laboratories to allow timely interventions when facing unexpected events.
