Transapical Beating-Heart Mitral Valve Repair Using a Novel Neochord Implantation System

We reported a successful beating-heart transapical mitral valve repair in a 78-year-old patient suffering severe mitral regurgitation with prohibitive surgical risk using MitralstitchTM system, a novel device distinguished by its’ implanted neochord mimicking the surgical pledgeted suture and the retrievable positioner facilitating leaflet capture. This technology would be a competitive option for high-risk patients with severe mitral regurgitation due to leaflet prolapse.

There really doesn’t seem to be in sight to Boston Scientific’s recent buying spree. This time the Marlborough, Mass.-based company is picking up Claret Medical for about $220 million in upfront cash and a potential reimbursement-based milestone payment of up to $50 million. The deal is set to close sometime in the third quarter of 2018. Santa Rosa, CA-based Claret has developed and received clearance for the Sentinel Cerebral Embolic Protection System. The device is used to protect the brain during certain interventional procedures, predominately in patients undergoing transcatheter aortic valve replacement(TA...

Boston Scientific (NYSE:BSX) said today that it agreed to pay as much as $270 million to acquire Claret and its Sentinel device. Marlborough, Mass.-based Boston Scientific said the deal involves an ip-front cash payment of $220 million and another $50 million pegged to a reimbursement milestone. Claret’s Sentinel device is designed to trap and remove debris dislodged during transcatheter aortic valve replacements to prevent stroke and other neurological damage. After landing CE Mark approval in the European Union in 2014, Santa Rosa, Calif.-based Claret won de novo clearance from the FDA last year for the Sentin...

AbstractIn patients with aortic regurgitation (AR), a precise preoperative assessment of aortic valve (AV) pathology is important if AV repair or sparing operation is an alternative option. The aim of this study was to assess the diagnostic accuracy of computed tomography (CT) for evaluating the AR mechanism compared with surgical inspection. 59 patients with AR who underwent AV surgery and preoperative cardiac CT were evaluated. AR mechanism was classified into type 1 (aortic dilatation or cusp perforation), type 2 (prolapsed cusp) and type 3 (cusp retraction). Agreement between CT and surgical inspection was obtained. Co...

Conclusions: The bending angle of AML which was considered as quantification of mobility and flexibility of AML can be a predictor for MV repair in patients with rheumatic heart disease (RHD). The small single area of commissural calcification had no effect on reparability of rheumatic MV disease. WS cannot appropriately predict the outcome of rheumatic MV repair. PMID: 29997956 [PubMed]

Conclusions: Our preliminary findings showed that the surgical outcome of mitral valve repair might be comparable to that of MVR in terms of early mortality and long-term survival. However, mitral valve repair was associated with a higher residual or recurrent mitral regurgitation rate. According to the latest literature, the role of MVR can justifiably be indicated for severe IMR. As for moderate IMR, CABG alone without mitral valve intervention may provide similar clinical outcomes. PMID: 29997945 [PubMed]

In conclusion, despite significant MR regression in all MR groups, some individuals may require additional mitralvalve repair after TAVI. According to our data the timing of these procedures should be based on the underlying MR etiology. The Carpentier classification in patients with coincidental MR undergoing TAVI for severe AS may also have prognostic implications as we found an increased incidence of strokes in our LA functional cohort and a worse mortality rates in organic MR.

Abstract BACKGROUND: Contemporary outcomes of complete atrioventricular septal defect (CAVSD) repair, particularly for defects with associated abnormalities, is unclear. The goal of this study is to report an all-inclusive experience of CAVSD repair using a consistent surgical approach. METHODS: All patients undergoing CAVSD repair between 1995 and 2016 at our institution were included. Patients were divided into 2 groups: isolated and complex (tetralogy of Fallot (TOF), aortic arch repair, double outlet right ventricle (DORV), and total anomalous pulmonary venous return (TAPVR)). Survival and reoperation wer...
