Annuloplasty rings fashioned from Dacron tube grafts have been used in mitral valve operations at the Texas Heart Institute for the past 3 years. This technique has been applied in 70 consecutive patients, with excellent clinical and echocardiographic results. We have found that annuloplasty rings constructed from transverse sections of knitted Dacron offer the same advantages as other flexible rings at a greatly reduced cost.

Aortic valve replacement is the common treatment of choice for severe aortic valve insufficiency (AI). AI is often caused by aortic root dilatation which leads to valve incompetence despite structurally normal valve leaflets. For this condition, aortic repair surgery with ring annuloplasty is considered a potentially superior option.

There are several types of annuloplasty devices for mitral repair. We present a totally-thoracoscopic robotic mitral repair using a new semi-rigid ring with a nitinol core that makes it malleable so that it can be inserted through a trocar. This technique combines the advantages of semi-rigid rings and a totally-thoracoscopic approach, which may further expand this approach to other aetiologies.

Background: Left ventricular outflow tract (LVOT) obstruction is a common, often fatal complication of transcatheter mitral valve replacement (TMVR). Laceration of the anterior mitral leaflet to prevent outflow obstruction (LAMPOON) was safe and effective at preventing LVOT obstruction at 30 days in the National Heart, Lung, and Blood Institute LAMPOON trial.
Objectives: The authors report the 5-year outcomes of intentional anterior mitral leaflet laceration before SAPIEN 3 TMVR, in patients at risk of LVOT obstruction.

Annuloplasty should always accompany mitral valve repair in order to achieve proper annular remodeling and stabilization. Numerous types of annuloplasty rings-that differ from rigid to semi-rigid and flexible devices, from complete to partial, and from flat to saddle-shaped rings-are clinically available. A deeper understanding of mitral valve function, in conjunction with several recent studies, suggest it is advisable to prefer annuloplasty rings that mimic the physiological mitral annulus shape and three-dimensional (3D) dynamic changes in order to reduce haemodynamic stress on valve components and optimize leaflet coaptation, perhaps improving valve repair durability too.
