“…The characteristics of patients identified in this study met the criteria of Ambler et al [5], which are: Demographic characteristics: gender, age, cardiac arrhythmias, ejection fraction, systemic arterial hypertension, diabetes, BMI, renal failure (in case of serum creatinine ratio greater than 2.4 mg/dL and/or the performing of dialysis), functional class (according to the model proposed by the NYHA), type of valve lesion (aortic, mitral or mitral-aortic) and previous heart surgery. Operative characteristics: time of surgery, associated surgery (CABG and tricuspid surgery), surgical valve reintervention and type of surgery (elective, urgent or emergency).…”

“…It represents the technical quality of the surgical team, and decisively influences the recommendation of surgical intervention. This risk is little affected by the type of valve replacement [5,6], but is influenced by various demographic and operative factors, which are known to be able to affect immediate morbidity and mortality related to the procedure.…”

“…This study aims to verify whether the immediate surgical result in heart valve replacement with St. Jude-Biocor bovine pericardium bioprosthesis in patients operated at the Institute of Cardiology of Rio Grande do Sul meets the standard observed in the study of Ambler et al [5], in order to gauge the score's validity in assisting in the management of patients to be operated in the institution. This study also hopes to quantify the influence of factors recognized as risk factors in the surgical procedure presented herein.…”

“…The creation of databases containing information about large numbers of patients operated in single or multiple centers allows for the development of risk scores for heart valve surgery [5] as well as other heart surgeries [7][8][9][10], and is similar to the EuroSCORE [11] and the Parsonnet [12]. These scores allow us to estimate the patient's individual immediate surgical risk.…”

“…It helps in recommendations for the procedure; it helps clarify things for the patient and their family, it is a resource for the surgical team, and it leads to more favorable outcomes by minimizing or neutralizing the indentified risk factors. However, the implementation of risk scores in medical centers different from where the data originated can lead to differing conclusions [5][6][7][8][9][10][11][12][13].…”

odds-ratio (OR).Results: The mortality rate was 14.3%, which was higher than the estimated mortality rate (3%, according to Ambler's mean score of 6, (p<0.01)). Patients who died presented a mean score of 8.26, which was higher than the survivors' average score of 5.68. Characteristics of increased risk were emergency surgery (OR=10.87), dialysis (OR=6.10), and age higher than 80 years (OR=6.10). Our sample indicates an area under the ROC curve of 72.9% (accepted value > 70%). Conclusion

Pigtail catheter “propping” for MitraClip percutaneous transcatheter mitral valve repair

In recent years percutaneous therapy has emerged as a feasible and effective option for the treatment of mitral regurgitation, particularly in cases where the risks of conventional cardiac surgery are prohibitively high. To date the most widely used percutaneous approach is beating heart, edge-to-edge repair with the MitraClip device (Abbott Vascular-Structural Heart, Menlo Park, CA). The technique requires simultaneous grasping and approximation of both mitral valve leaflets prior to securing and releasing the clip. However, this may be technically challenging or indeed impossible in patients with failure of coaptation, particularly when there is a large coaptation gap. We present an approach for overcoming this relatively common obstacle based on "propping" the anterior mitral valve leaflet toward its posterior counterpart with a diagnostic pigtail catheter to reduce the coaptation gap and to allow grasping of both leaflets without difficulty. © 2016 Wiley Periodicals, Inc.

Transcatheter mitral valve repair (TMVR) using MitraClip (MC) is now an established technique in the interventional treatment of mitral regurgitation.Common complications after MC procedure are bleeding and ischemic events. However, 2017 ESC/EACTS and 2020 ACC/AHA did not give a clear antithrombotic protocol, the policy has been based on clinical experience. Here, we performed a meta-analysis comparing outcomes with and without the addition of anticoagulants after TMVR. We searched the Cochrane Library, EMBASE, PubMed, and Web of Science from inception to October 6, 2022 to identify studies with or without the use of anticoagulants after TMVR. From each study, we extracted the number of people with bleeding, stroke, combined endpoints, and all-cause death. Five observational cohort studies were included, enrolling a total of 1892 patients undergoing TMVR who were assigned to either the anticoagulation group (n = 1209) or the no-anticoagulation group (n = 683). Pooled analysis showed a significantly lower stroke rate in the anticoagulated group (at least 4 weeks duration) compared with the non-anticoagulated group (RR [95% CI] = 0.14 [0.0−0.77], p = 0.02), and similar rates of bleeding, combined endpoints, and allcause death in both groups (RR [95% CI] = 0.76 [0.48−1.22], p = 0.26), (RR [95% CI] = 0.52 [0.10−2.63], p = 0.43), and (RR [95% CI] = 0.89 [0.58−1.35], p = 0.58). We observed a reduced risk of stroke without elevated risk of bleeding, combined endpoints, or all-cause death in patients using anticoagulants (at least 4 weeks duration) after TMVR compared to no anticoagulants.
