Continuous Suture Technique for Aortic Valve Replacement Shortens Cross-Clamp and Bypass Times.

Summary of "Continuous Suture Technique for Aortic Valve Replacement Shortens Cross-Clamp and Bypass Times."

The interrupted noneverting mattress suture technique is typically used in conventional surgical aortic valve replacement. The continuous suture technique, although faster, has been associated with a higher incidence of paravalvular leak. Using a slightly modified technique to minimize this risk, we investigated whether continuous suturing would shorten aortic cross-clamp time in aortic valve replacement in comparison with interrupted suturing. We reviewed the cases and compared the perioperative data of 60 consecutive patients in Japan and Australia (35 men and 25 women; median age, 70 yr) who had undergone aortic valve replacement with or without septal myectomy. The continuous suture technique had been used in 41 patients (Group CS) and the standard interrupted suture technique in 19 (Group IS). The groups were similar in age, sex, pathologic valvular conditions, and operative urgency. In Group CS, aortic cross-clamp time (47 vs 63 min; P=0.0001) and cardiopulmonary bypass time (76 vs 89 min; P=0.04) were significantly shorter. Neither group had early paravalvular leak. Using our continuous suture technique safely shortened aortic cross-clamp time during surgical aortic valve replacement.

Medical and Biotech [MESH] Definitions

Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.

The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.

Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).

A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
