Clinical experience with the Ventrica distal anastomotic device in coronary surgery

Abstract

The surgical treatment of coronary artery disease is based on bypassing demonstrated lesions with autogenous vascular grafts. The operations have traditionally been invasive, complicated procedures requiring skillful microvascular surgical technique, cardiopulmonary bypass, and temporary cardioplegia. Ventrica, Inc. has developed a coupling device based on magnetic attraction which simplifies the connection of the graft to the coronary artery. Perceived advantages are shortened operating time, the need for less operative exposure, ease of use, versatility, and reliability. Use of the device is easily learned. It is a gentle technique which may be abandoned at any point without grossly noticeable consequence; the vessel remains apparently undamaged and remains suitable for hand-sewn anastomosis. Patient recovery is swift and acceptance high. Immediate operative results, pre-discharge angiograms and 6 month follow up angiograms are all favorable. The device is applicable to multiple graft operations, to all autogenous graft conduits, to end or sequential anastomoses, and to potentially all coronary vessels.

Magnetic connectors for coronary surgery: What do we know a decade later?

“…Disappointingly, long term patency outcomes of the latter recipients of MVP mediated anastomoses have never been investigated, and therefore the status of the patients and the anastomoses beyond discharge de facto is not known. On the basis of a second clinical trial, concerning exclusively LITA to LAD MVP anastomoses, Klima and colleagues were able to demonstrate in their single center experience in Hannover a 100% six-months angiographic graft patency rate of the MVP in this position (9). However, angiographic evaluation of the MVP device was studied only in a subset of the original patient cohort used (23/48, one patient died), giving a follow-up study population of just 47,9%.…”

Choledochojejunostomy with an innovative magnetic compressive anastomosis: How to determine optimal pressure?

“…Mimuro et al [9] and Akita et al [10] reported many cases of the successful application of magnamosis for biliary strictures and biliary anastomoses in liver transplantation. In 2003, the Ventrica company launched magnetic devices used for vascular side-toside anastomosis, and these devices were clinically successful [11,12] . Magnamosis has been proven to be a safe surgical technique that is equivalent or superior to anastomosis created by the hand-sewn or stapling technique [13] .…”
