1. 慢性僧帽弁閉鎖不全症の血管拡張療法vasodilator therapy in chronic mitral regurgitation [show details]
…An overview of the management of chronic MR is presented separately. The volume of mitral regurgitant volume (MRV) is determined hydraulically by two factors: The duration (D) and magnitude of the systolic …
2. 成人における重度の慢性大動脈弁閉鎖不全症の血管拡張療法vasodilator therapy in severe chronic aortic regurgitation in adults [show details]
…in patients with severe chronic AR is aimed at reducing the hemodynamic burden by reducing regurgitant volume. However, the efficacy of vasodilator therapy has not been established in asymptomatic AR as …
3. 僧帽弁逸脱および僧房弁のflailによる慢性僧帽弁閉鎖不全症の自然経過natural history of chronic mitral regurgitation caused by mitral valve prolapse and flail mitral leaflet [show details]
…of the regurgitant volume by more than 8 mL occurred in 11 percent. Progression of the regurgitant volume by more than 8 mL occurred in 51 percent. The mean rate of increase in regurgitant volume was 5 …
4. 大動脈疾患患者や僧帽弁疾患患者に行う非心臓手術での麻酔anesthesia for noncardiac surgery in patients with aortic or mitral valve disease [show details]
…faster HR limits the duration of diastole when aortic valvular regurgitation is occurring; thus, regurgitant volume is reduced. Avoid bradycardia. Bradycardia associated with hypotension is treated with bolus …

A Unifying Concept for the Quantitative Assessment of Secondary Mitral Regurgitation.

Bartko PE, Arfsten H, Heitzinger G, Pavo N, Toma A, Strunk G, Hengstenberg C, Hülsmann M, Goliasch G.
Journal of the American College of Cardiology. 2019 May;73(20)2506-2517.
Diverging guideline definitions for the quantitative assessment of severe secondary mitral regurgitation (sMR) reflect the lacking link of the sMR spectrum to mortality and has introduced a source of uncertainty and continuing debate. The current study aimed to define improved risk-thresholds specif

Causes and mechanisms of isolated mitral regurgitation in the community: clinical context and outcome.

Dziadzko V, Dziadzko M, Medina-Inojosa JR, Benfari G, Michelena HI, Crestanello JA, Maalouf J, Thapa P, Enriquez-Sarano M.
European heart journal. 2019 May;().
To define the hitherto unknown aetiology/mechanism distributions of mitral regurgitation (MR) in the community and the linked clinical characteristics/outcomes. We identified all isolated, moderate/severe MR diagnosed in our community (Olmsted County, MN, USA) between 2000 and 2010 and classified MR
