Surgical treatment for aortic root infection：recent insights including requirement of homograft replacement

session outline

For critical conditions with severe infective endocarditis with root abscess or graft infection after aortic root replacement, the usefulness of root replacement with aortic valve homograft was once addressed. However, due to shortness of homograft and difficulty of its use in Japan, it has been carried out at limited institutions. At the other centers, alternative surgical procedures including AVR with patch closure of annular abscess, standardized Bentall operation, xenograft replacement, and Ross procedure have been carried out. In this session, we would discuss the recent insights including the long-term outcome of homograft root replacement and the validity of other procedures.

Aoritc valve selection and its long term result for young patients under 60 years old

session outline

In the TAVI era, valve selection of AVR is about to change significantly. The AHA / ACC Guideline 2020 also recommends class I for selecting TAVI valves for people aged 65 and over, regardless of risk stratification. In the future, it is expected that young people will be required to select a valve as a comprehensive treatment strategy throughout the patient's life span in consideration of future TAVI and valve in valve. Therefore, in this symposium, I would like you to discuss the future direction of young AVR by showing the valve selection of young (under 60 years old) AVR and its long-term results, which are the basic data of the comprehensive strategy. Mechanical valve, biological valve, Ross procedure, Homograft or TAVI valve?

The important issues to be discussed will include device selections, concomitant valve procedures, management of right heart failure, care for drive-line infection, prevention of bleeding/thromboembolic complications, and their future visions in the DT patients.

Surgical strategy for congenital aortic valve diseases on children, adolescents and young adults

session outline

Anatomical aortic valves that require surgical intervention in the childhood and AYA generation are accompanied by both narrow annulus and leaflet abnormalities associated with congenital dysplasia and/or hypoplasia. In most cases, they cannot be inserted by the usual valve replacement procedure, even using the smallest mechanical valves on the market. In recent years, several procedures have been recommended and performed at each institute, including valve repair (including cusp replacement procedures like the Ozaki’s one), Ross operation (including the Ross-Konno), and artificial valve replacement using annulus enlargement procedures including Konno’s one. In this symposium, we would like to get recent information in this area and hope to have reasonable consensus and future direction, for the patients.

Atrial Fibrillation in Mitral Valve Patients: Maze procedure vs. LA appendage Occlusion

session outline

A variety of surgical procedures are performed in mitral valve patients with AF. Maze procedure is expected to bring utmost effects to the patients by restoration of sinus rhythm and resection of the LA appendage, but also prolong operation and ischemic times and may increase the incidence of permanent pacemaker implantation. Occlusion of the LA appendage alone may reduce the risk of thromboembolic stroke, but may not convert AF. We will elucidate the characteristics of these procedures and discuss the indication for the AF patients undergoing mitral valve procedures in this debate session.
