Is trans-apical off-pump neochord implantation a safe and effective procedure for mitral valve repair?
Article in Anatolian journal of cardiology, 2019. 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
objectiveTrans-apical off-pump mitral valve repair is a new minimally invasive surgical technique for the correction of mitral regurgitation caused by mitral leaflet prolapse. The purpose of this study is to evaluate, using clinical and echocardiographic follow-up data, the mid-term results of patients undergoing this procedure.
methodsA total of 26 patients diagnosed with severe mitral regurgitation underwent mitral valve repair with trans-apical off-pump neochord implantation using the NeoChord device at our hospital from July 2015 to July 2017. All patients were examined by transthoracic and transesophageal echocardiography. Eighteen (69.2%) patients had type A anatomy, 4 (15.4%) had type B anatomy, and 4 (15.4%) had type C anatomy. Preoperative, intraoperative, and postoperative demographic, echocardiographic, and clinical data were collected.
resultsThe patients' age ranged from 33 to 76 years (mean: 56±10.1 years). The average preoperative EuroSCORE II was 1.04%±0.7%. Acute procedural success was achieved in 25 (96.15%) patients. There was only 1 early death (30-day mortality rate: 3.8%) due to postoperative low cardiac output syndrome. Transthoracic echocardiography examinations revealed trivial/mild mitral regurgitation in 87.5% of the patients and moderate regurgitation in 12.5% of the patients. During the follow-up period, transthoracic echocardiography examinations revealed trivial/mild mitral regurgitation (MR) in 14 (58.3%) patients. Six (25%) patients presented with moderate MR and 4 (16.7%) patients had severe MR. At the 30-month follow-up, freedom from residual severe MR was 78.8%±10.3% and freedom from reoperation was 87.5%±6.8%.
conclusionTrans-apical off-pump mitral valve repair with neochord implantation may be a suitable treatment option in patients with isolated posterior mitral valve leaflet prolapse.
