“…While mitral stenosis has been proven to be associated with compromised left ventricle compliance and reduced ventricular chamber size, due to cardiac remodeling (smallness) and mechanical constraint [Liu 1992], it is not hard to conclude that the SCLV incidence in this study population is sure to be higher. It was also found that there were more female patients in the SCLV group (79% female), consistent with previous studies [Kou 2014;Popov 2013]. This also helped explain the smaller body size of SCLV patients and the lower smoking history of SCLV patients since smokers in China were primarily male.…”

“…The incidence of SCLV in our single-centered cohort was 13.57%. A previous study from Popov et al, 2013, using EDV ≤ 75 ml as a cut-off value for SCLV, reported incidences of SCLV to be about 7.0% in patients undergoing MVR in a Ukrainian population [Popov 2013]. In the Asian population, especially the Eastern Chinese population, mitral stenosis was considered to occur more frequently than in western populations, due to rheumatic causes.…”

“…Moreover, one report suggested that SCLV could be a risk factor for left ventricular outflow tract obstruction after MVR [Jett 1986]. A further study showed that patients with SCLV were at higher risk for surgery with and increasing risk of prosthesispatient mismatch (PPM) [Popov 2013]. However, our previous research demonstrated that, although mitral PPM was associated with small left ventricle, it was not associated with poorer early-and mid-term outcomes after MVR in patients with rheumatic mitral valve stenosis [Akuffu 2018].…”

Background: Small cavity left ventricle (SCLV) may affect the clinical outcomes of patients undergoing mitral valve replacement (MVR). This study aims to investigate the incidence of SCLV in patients with rheumatic mitral valve stenosis undergoing MVR and analyze its effect on short-term patient outcomes. Methods: We retrospectively examined all consecutive patients with isolated or concomitant MVR for rheumatic mitral valve stenosis in our center from 2013 to 2018. SCLV was defined as end-diastolic volume index ≤ 50 ml/m2. After inclusion and exclusion, a total of 1,437 patients were analyzed. The baseline information was collected and compared between SCLV and non-SCLV patients. Multivariate logistic regression analysis was conducted to determine the effect of SCLV on early mortality. Results: A total of 1,437 patients were included in the study. SCLV was detected in 13.57% of the patients. Compared with the non-SCLV group, patients with SCLV were smaller-sized and primarily female. There were no significant differences between SCLV and non-SCLV patients regarding major postoperative complications, nor were there incidence of prosthesis-patient mismatch. Logistic regression analysis showed that SCLV was not a risk factor for short-term mortality (P = 0.998). Conclusions: Our results demonstrated that SCLV was not associated with poorer early outcomes after MVR surgery in patients with rheumatic mitral valve stenosis.

“…Mitral valve stenosis (MS) in adults especially due to rheumatic heart disease may be associated with a smaller than normal left ventricular cavity. This might be attributed to inadequate left ventricular preloading or chronic myocardial damage due to rheumatic heart disease resulting in left ventricular atrophy [1]. Sudden increase of blood inflow from the left atrium to the small "unprepared" left ventricle after mitral valve replacement (MVR) in such cases may lead to hemodynamic instability either during weaning from cardiopulmonary bypass (CPB) or in the early postoperative period manifested by the need for inotropic support and even mortality due to low cardiac output (COP) syndrome [2].…”

Background: Mitral valve stenosis in adults especially due to rheumatic heart disease may be associated with a smaller than normal left ventricular cavity. Mitral valve replacement in such cases may lead to hemodynamic instability either during weaning from cardiopulmonary bypass or in the early postoperative period manifested by the need for inotropic support and even mortality due to low cardiac output syndrome. Patients and methods: 184 patients with predominately severe stenotic mitral valves who underwent elective isolated mitral valve replacement in the period between January 2012 and January 2018 at our hospital were included in this study. Patients were divided into 2 matched groups; (small LV group) consisting of 86 cases and (normal or dilated LV group) consisting of 98 cases. Results: There were no statistically significant differences in operative details among both groups apart from the need for inotropic support and intra-aortic balloon pump due to low cardiac output which were statistically significantly higher in (small LV group) than (normal or dilated LV group) with a p-values of 0.01 and 0.03 respectively. Within the ICU stay only the incidence of occurrence of heart failure was significantly higher in (small LV group) with a p-value of 0.008. No statistically significant difference could be elicited in the in-hospital mortality between both groups (p-value = 0.1). Conclusion: Patients with mitral valve stenosis and small left ventricular cavity are in a higher need for inotropic and even mechanical support after mitral valve replacement as well as at a higher risk for the development of heart failure before hospital discharge than patients with mitral stenosis and normal-sized left ventricular cavity.
