“…Previous studies [23, 77,85,86,87,88,89] identified the preoperative predictors of MVA failure as larger LV diameter, sphericity index, mitral annulus diameter, mitral valve tenting area and MR severity (table 3). In a recent study from our group [23], a mitral valve tenting area ≥2.5 cm 2 , a coaptation distance ≥1 cm and a posterior leaflet angle ≥45° measured by TTE had a good sensitivity and specificity to predict persistent MR following MVA (table 3).…”

Ischemic Mitral Regurgitation: A Complex Multifaceted Disease

Ischemic mitral regurgitation (MR) is a complex multifactorial disease that involves global and regional left ventricular remodeling as well as dysfunction and distortion of the components of the mitral valve including the chordae, annulus and leaflets. This is a frequent (13–59%) complication of myocardial infarction, which is associated with a poor prognosis. The suboptimal results obtained with the most commonly used surgical strategy, that is, restrictive annuloplasty combined with coronary artery bypass graft, emphasize the need to develop alternative or concomitant surgical techniques that directly target the causal mechanisms of the disease. A comprehensive assessment of mitral valve configuration and left ventricular geometry and function prior to surgery as well as an accurate quantification of MR severity at rest and during exercise may help improve patient risk stratification and better individualize the surgical strategy based on the patient’s specific characteristics. The purpose of this review is to summarize the current state of knowledge with regard to the definition, prevalence, mechanisms, outcome and treatment of ischemic MR.

“…These latter studies only included general cardiac or coronary artery surgery (CAS) patients. It is unknown if similar superiority also applies to patients after valvular surgery (VS) expected to have a diminished left ventricular systolic and diastolic function after surgery, following chronic volume or pressure overload [2,6,[20][21][22][23]. Whereas La Place's law describes that ventricular radius and thus volume interacts with filling pressure to reflect ventricular preload, i.e.…”

While volumes are equally useful in monitoring fluid responsiveness, the predictive and monitoring value of PAOP is greater after VS than after CAS. In contrast, the CVP is of similar value as volume measurements in monitoring fluid responsiveness after CAS. The different value of pressures rather than of volumes between surgery types is likely caused by systolic left ventricular dysfunction in VS. The study suggests an effect of systolic cardiac function on optimal parameters of fluid responsiveness and superiority of the pulmonary artery catheter over transpulmonary dilution, for haemodynamic monitoring of VS patients.

“…Regurgitation degree. Patients with mitral annular diameter ≥ 3.7 cm with a tenting area of ≥ 1.6 cm 2 in long axis view and an IMR grade > 3.5 have a 50% probability of regurgitation recurrence during follow-up 30 . Hung et al 29 reported that recurrence of IMR after ring annuloplasty is due to progression of ventricular remodelling as shown by increase in LV volume and sphericity index.…”
