Causes and predictors of readmission after transcatheter aortic valve implantation : A meta-analysis and systematic review.

BACKGROUND: Since readmission rate is an important clinical index to determine the quality of inpatient care and hospital performance, the aim of this study was to explain the causes and predictors of readmission following transcatheter aortic valve implantation (TAVI) at short-term and mid-term follow-up. METHODS AND RESULTS: A systematic review and meta-analysis of all published articles from Embase, Pubmed/MEDLINE, and Ovid was carried out. In all, 10 studies including 52,702 patients were identified. The pooled estimate for the overall event rate was 0.15, and cardiovascular causes were the main reason for 30-day readmission (0.42, 95% confidence interval [CI]: 0.39-0.45). In addition, the pooled incidence of 1­year readmission was 0.31, and cardiovascular events were still the main cause (0.41, 95% CI: 0.33-0.48). Patients with major and life-threatening bleeding, new permanent pacemaker implantation, and clinical heart failure were associated with a high risk for early readmission after TAVI. Moreover, an advanced (≥3) New York Heart Association classification, acute kidney injury, paravalvular leak, mitral regurgitation (≥ moderate), and major bleeding predicted unfavorable outcome to 1­year readmission. Female gender and transfemoral TAVI was associated with a lower risk for unplanned rehospitalization. CONCLUSIONS: This meta-analysis found cardiovascular factors to be the main causes for both 30-day and 1­year rehospitalization. Heart failure represented the most common cardiovascular event at both short-term and mid-term follow-up. Several baseline characteristics and procedure-related factors were deemed unfavorable predictors of readmission. Importantly, transfemoral access and female gender were associated with a lower risk of readmission.

Rare association of two cardiovascular malformations successfully corrected in a single surgery: a case report.

BACKGROUND: Partial anomalous pulmonary venous connection (PAPVC) without an atrial septal defect (ASD) associated with coarctation of the aortic arch is a rare congenital cardiac anomaly. This rare combination is only described in a few studies; none report the correction of these two malformations in a single surgery. CASE PRESENTATION: A 5-year-old girl was admitted to our hospital because the echocardiography revealed coarctation of the aortic arch; this diagnosis was confirmed by computed tomography (CT), which also showed her left superior pulmonary vein draining into the vertical vein without ASD (Fig. 1). She exhibited no special clinical symptoms. Her upper-limb blood pressure was approximately 110/90 mmHg, whereas her lower-limb blood pressure was approximately 75/50 mmHg. CONCLUSIONS: We surgically repaired the case of PAPVC to the vertical vein with aortic coarctation, in which the two cardiovascular malformations were corrected in a single surgery without cardiopulmonary bypass.
