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.

ConclusionIn conclusion, root remodeling is a viable option in valve-preserving root replacement. If combined with careful assessment and, if necessary, correction of aortic valve form reproducible restoration of aortic valve function can be achieved.

auml; T Abstract BACKGROUND: Operative mortality after complete atrioventricular septal defect (cAVSD) repair has improved vastly. Less improvement has been demonstrated regarding late mortality and reoperation rates. There is evident lack of comprehensive population-based studies analyzing the history and progress of the ever-changing operative results. METHODS: This is a 5-million population-based retrospective study of consecutive 388 cAVSD patients operated in Finland between 1962 and 2014. Data was collected using Children's Cardiac Surgical Registry of Children's Hospital at the Helsinki University Hosp...

Abstract BACKGROUND: Contemporary outcomes following surgical management of thoracic aortic disease have improved; however, the impact of sex-related differences is poorly understood. METHODS: A total of 1653 patients (498 (30.1%) female) underwent thoracic aortic surgery with hypothermic circulatory arrest between 2002 and 2017 in ten institutions of the Canadian Thoracic Aortic Collaborative. Outcomes of interest were in-hospital death, stroke and a modified Society of Thoracic Surgeons-defined composite (STS-COMP) for mortality or major morbidity (stroke, renal failure, deep sternal wound infection, reoper...

Early stage cardiovascular intervention tech developer CardioMech AS said today that it raised $2.5 million in a convertible note financing round. The Oslo-based company said that the round was significantly oversubscribed, and included investments from experienced angel investors. CardioMech is developing a transcatheter alternative to cardiac surgery for the placement of artificial chords for the mitral valve, according to the company’s website. The company’s initial tech will focus on high risk patients suffering from severe symptomatic degenerative mitral regurgitation due to props or flail. “This fin...

We report treatment following a type A post-dissection thoraco-abdominal aneurysm in a patient who previously underwent ascending aortic reconstruction using a biological aortic valve and Dacron prosthetic graft implantation in emergency conditions.The multi-staged approach consisted in removing the right kidney and performing a heterotopic autotransplantation in the left iliac fossa before positioning a fenestrated endograft (celiac trunk, superior mesenteric artery and left renal artery).

Abstract Valve-sparing aortic root replacement is one of the effective repairs for aortic regurgitation resulting from progressive dilatation of the aortic root late after surgical correction of conotruncal anomaly. However, feasibility and effectiveness of this procedure are unknown for unrepaired physiology. A 32 year-old man presented with unrepaired Tetralogy of Fallot (TOF) and moderate aortic regurgitation with severe left ventricular dysfunction. Valve-sparing aortic root replacement and TOF repair were simultaneously performed. Six months after the surgery, aortic regurgitation remained trivial. Concomitan...

Since the initial description of the composite valve-graft technique for repair of aneurysms of the aortic root and ascending aorta with associated aortic valve disease by Bentall and De Bono in 1968, modifications have been introduced to reduce the risks of major bleeding and false aneurysm formation that were associated with this procedure. Currently, the most widely used modification involves excision of the aortic valve, aortic root, and ascending aorta, suture of a composite graft into the aortic root and to the ascending aorta, mobilization of the coronary arteries with a small rim of aortic tissue, and anastomosis o...
