National trends and 30-day readmission rates for next-day-discharge transcatheter aortic valve replacement: An analysis from the Nationwide Readmissions Database, 2012-2016.

Transcatheter aortic valve replacement (TAVR) has evolved toward a minimalist approach, resulting in shorter hospital stays. Real-world trends of next-day discharge (NDD) TAVR are unknown. This study aimed to evaluate underlying trends and readmissions of NDD TAVR. METHODS: This study was derived from the Nationwide Readmissions Database from 2012 to 2016. International Classification of Diseases, Ninth and Tenth Revisions, codes were used to identify patients. Any discharge within 1 day of admission was identified as NDD. NDD TAVR trends over the years were analyzed, and any admissions within 30 days were considered readmissions. A hierarchical logistic regression model was used to identify predictors of readmission. RESULTS: Of 49,742 TAVR procedures, 3,104 were NDD. The percentage of NDD TAVR increased from 1.5% (46/3,051) in 2012 to 12.2% (2,393/19,613) in 2016. However, the 30-day readmission rate remained the same over the years (8.6%). The patients' mean age was 80.3 ±â€¯8.4 years. Major readmission causes were heart-failure exacerbation (16%), infections (9%), and procedural complications (8%). In 2016, there were significantly higher late conduction disorder and gastrointestinal bleeding readmission rates than in 2012-2015. Significant predictors of readmission were anemia, baseline conduction disease, cardiac arrhythmias, heart failure, chronic kidney disease, chronic obstructive pulmonary disease, neoplastic disorders, and discharge to facility. CONCLUSIONS: The percentage of NDD TAVR increased over the years; however, readmission rates remained the same, with a higher rate of conduction abnormality-related hospitalizations in 2016. Careful discharge planning that includes identification of baseline factors that predict readmission and knowledge of etiologies may further prevent 30-day readmissions.

Readmission-free period and in-hospital mortality at the time of first readmission in acute heart failure patients-NRD-based analysis of 40,000 heart failure readmissions.

The 30-day readmission rates, predictors, and outcomes for acute heart failure (AHF) patients are well published, but data beyond 30 days and the association between readmission-free period (RFP) and in-hospital readmission-related mortality remain unknown. We queried the National Readmission Database to analyze comparative outcomes of AHF. Patients were divided into three groups based on their RFP: group 1 (1-30 days), group 2 (31-90 days), and group 3 (91-275 days). AHF cases and clinical variables were identified using ICD-9 codes. The primary outcome was in-hospital mortality at the time of readmission. A total of 39,237 unplanned readmissions occurred within 275 days; 15,181 within group 1, 11,925 within group 2, and 12,131 within group 3. In-hospital mortality in groups 1, 2, and 3 were 7.4%, 5.1%, and 4.1% (p < 0.001). Group 1 had higher percentages of patients with cardiogenic shock (1.3% vs. 0.9% vs. 0.9%; p < 0.001), acute kidney injury (30.2% vs. 25.9% vs. 24.0%; p < 0.001), dialysis use (8.6% vs. 7.5% vs. 6.9%; p < 0.001), and non-ST elevation myocardial infarction (4.4% vs. 3.8% vs. 3.6%; p < 0.001), but there was no statistical difference among the three groups for ST-elevation myocardial infarction, percutaneous coronary intervention (PCI), or ventricular assist device use at the time of index admission. However, group 3 had higher PCI (1.7%) compared with groups 1 and 2 (p < 0.001). In multivariable logistic regression, groups 2 and 3 had odd ratio of 0.70 and 0.55, respectively, for in-hospital mortality compared with group 1. Longer RFP is associated with decreased risk of in-hospital mortality at the time of first readmission.

Etiologies and predictors of readmission among obese and morbidly obese patients admitted with heart failure.

The relationship between severity of obesity and outcomes in heart failure (HF) has long been under debate. We studied index HF admissions from the 2013-14 National Readmission Database. Admissions were separated into three weight-based categories: non-obese (Non-Ob), obese (Ob), and morbidly obese (Morbid-Ob) to analyze hospital mortality and readmission at 30 days and 6 months. We investigated etiologies and predictors of 30-day readmission among these weight categories. We studied a total of 578,213 patients of whom 3.0% died during index hospitalization (Non-Ob 3.3% vs. Ob 1.9% vs. Morbid-Ob 1.9%; p < 0.01). Non-Ob comprised 79.5%, Ob 9.9%, and Morbid-Ob 10.6% of patients. Morbid-Ob patients were the youngest among age categories and more likely to be female. In-hospital mortality during readmission at 30 days and 6 months was significantly lower among Morbid-Ob and Ob compared with Non-Ob patients (all p < 0.01). Thirty-day readmission among Morbid-Ob was lower than Non-Ob and higher than Ob patients (19.6% vs. 20.5% vs. 18.6%, respectively; p < 0.01). Morbid-Ob patients were less likely to be readmitted for cardiovascular etiologies compared with both Ob and Non-Ob (45.0% vs. 50.3% vs. 50.6%; p < 0.01). Multivariable regression analysis revealed that Ob (adjusted odds ratio 0.84, 95% confidence intervals 0.82-0.86) and Morbid-Ob (aOR 0.83, 95% CI 0.81-0.85) were independently associated with lower 30-day readmission. Readmission at 6 months was highest among Morbid-Ob followed by Non-Ob and Ob (51.1% vs. 50.2% vs. 49.1%, p < 0.01). Morbid-Ob and Ob patients experience lower in-hospital mortality during index HF admission and during readmission with 30 days or 6 months compared with Non-Ob. Morbid-Ob patients experience greater readmission at 6 months despite the lower rate at 30 days post discharge. Morbid-Ob patients are most likely to be readmitted for non-cardiovascular causes.

Impact of intracoronary imaging on in-hospital mortality and 30-day readmission rates following percutaneous coronary intervention: A nationwide readmissions database analysis.

BACKGROUND: Percutaneous coronary intervention (PCI) is well established for the treatment of obstructive coronary artery disease. This study was performed to assess the impact of in-hospital mortality and 30-day readmission with intracoronary imaging as an adjunct to baseline coronary angiography. METHODS: The study was derived from the Healthcare Cost and Utilization Project's National Readmission Database (NRD) of 2016, sponsored by the Agency for Healthcare Research and Quality. Patients who underwent PCI were identified using appropriate ICD-10 codes. Study population was further subcategorized into 2 PCI arms: intravascular imaging (''imaging'' group) and fluoroscopy guided (''angiography'' group). Primary endpoints were 30-day readmissions and in-hospital mortality. Secondary endpoints were length of stay, cost of care, predictors of 30-day readmission and in-hospital mortality in PCI related hospitalizations. RESULTS: We identified in total 188,368 index admissions, with 12,379 patients in the "imaging-guided" group and 175,989 in the "angiography-alone" group. There were no differences in 30-day readmissions between both groups (~10.8% in both arms, p = .788). However, in-hospital mortality carried a statistically significant reduction with use of imaging-guided PCI (1.72% vs 2.24%, p = .004). The median length of stay was longer in the imaging-guided arm (3 vs. 2 days, p < .001), associated with larger median total hospital costs ($32,123 USD vs. $25,162 USD, p < .001). The strongest predictor of in-hospital mortality in both univariate and multivariate analysis was having an existing coagulopathy. CONCLUSION: The results of this study did not confer benefit with regards to 30-day hospital readmission rates when utilizing intracoronary imaging versus angiography-alone in percutaneous coronary intervention, but did suggest there may be an association between the use of intracoronary imaging and improved in-hospital mortality. In addition, resource utilization was higher in the intra-coronary imaging arm of the study.

Utilization and procedural adverse outcomes associated with Watchman device implantation.

AIMS: The Food and Drug Administration (FDA) approval of the Watchman device [percutaneous left atrial appendage occlusion (LAAO)] has resulted in the widespread use of this procedure in many centres across the USA. We sought to estimate the nationwide utilization and frequency of adverse outcomes associated with Watchman device implantation. The objective of this study was to evaluate the Watchman device implantation peri-procedural complications and comparison of the results with the previous studies. METHODS AND RESULTS: The National Inpatient Sample (NIS) was queried for all hospitalizations with a primary diagnosis of atrial fibrillation or atrial flutter during the year 2016 with percutaneous LAAO during the same admission (ICD-10 code-02L73DK). The frequency of peri-procedural complications, including mortality, procedure-related stroke, major bleeding requiring blood transfusion, and pericardial effusion, was assessed. We compared the complication rates with the published randomized controlled trials and the European Watchman registry. An estimated 5175 LAAO procedures were performed in 2016. The majority of procedures was performed in males (59.1%), age ≥75 years (58.7%), and White (83.1%). The overall complication rate was 1.9%. The in-hospital mortality was 0.29%. Pericardial effusion requiring pericardiocentesis was the most frequent complication (0.68%). Bleeding requiring transfusion was noted in 0.1% of device implants. The rates of post-procedure stroke and systemic embolism were 0% and 0.29%, respectively. CONCLUSION: Percutaneous LAAO with the Watchman device in the USA is associated with low in-hospital complications and a similar safety profile to a recently published EWOLUTION cohort. The complication rates were lower than those reported in the major randomized clinical trials (RCTs). We report the frequency of peri-procedural complications of the LAAO using the Watchman device from the NIS database. We also compare the frequency of peri-procedural complications with the previously published RCTs and EWOLUTION cohort. Our findings are in concordance with findings from EWOLUTION cohort and compare favourably with RCTs.

Comparison of nationwide trends in 30-day readmission rates after carotid artery stenting and carotid endarterectomy.

OBJECTIVE: Carotid revascularization procedures, carotid artery stenting (CAS) and carotid endarterectomy (CEA), are among the most common vascular interventions performed in the United States, with significant resource utilization. Whereas multiple studies have reported outcomes after these procedures, data regarding 30-day readmission rates after these interventions remain scant. METHODS: The U.S. Nationwide Readmission Database (2010-2014) was queried to identify all patients ≥18 years who were readmitted within 30 days after a hospital discharge for CEA or CAS. RESULTS: Among 476,260 patients included, 13.5% underwent CAS and 86.5% underwent CEA. The combined 30-day readmission rate for all carotid revascularization procedures was 9.2% (10.6% after CAS and 9.0% after CEA). After 1:3 propensity matching, CAS was associated with higher risk of readmission compared with CEA (10.4% vs 9.4%). Neurologic complications and cardiac conditions were the two most common causes of readmission after both CAS (29.7% and 23.7%, respectively) and CEA (28.2% and 21.7%, respectively). The 30-day readmission rates were higher in CAS patients across all age groups as well as in those with a low or high baseline burden of comorbidities. CONCLUSIONS: In this large nationwide study, CAS was associated with higher 30-day readmission rates compared with CEA irrespective of age or baseline burden of comorbidities. Neurologic or cardiac adverse events were responsible for >50% of readmissions after CAS and CEA.

Predictors of 30-day re-admissions in patients with infective endocarditis: a national population based cohort study.

Infective endocarditis (IE) is a life threatening disease requiring lengthy hospitalizations, complex multidisciplinary management and high health care costs. In this study, we analyzed the National Readmissions' Database (NRD) to identify infective endocarditis cases and the causative organisms, clinical determinants, length of stay, in-hospital mortality, and 30-day hospital readmission rates. The study cohort was derived from Healthcare Cost and Utilization Project's National Readmission Database between 2010-15. We queried the National Readmissions' Database using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic code for infective endocarditis (421.0) and identified a total of 187,438 index admissions. SAS 9.4 (SAS Institute Inc., Cary, NC) was utilized for statistical analyses. A total of 187,438 patients with a primary diagnosis of IE were identified over 6 years (2010-2015). Twenty-four percent (44,151 patients) were readmitted within 30 days. Most common etiologies for readmission included sepsis (14%), acute heart failure (8%), acute kidney injury (6%), intracardiac device infection (5.6%) and recurrence of IE (2.7%). Predictors of increased readmissions included female sex, staphylococcus aureus infection, diabetes, chronic lung disease, chronic liver disease, acute kidney injury, acute heart failure and anemia. In-hospital mortality for the readmission of IE was 13%, and average length of stay during the re-admission was 12 days. IE is associated with high rates of index admission mortality and for 30-day readmissions of which are associated with a substantial risk of death.

Short-term outcomes associated with inpatient ventricular tachycardia catheter ablation.

BACKGROUND: Utilization of catheter ablation of ventricular tachycardia (VT) has steadily increased in recent years. Exploring short-term outcomes is vital in health care planning and resource allocation. METHODS: The Nationwide Readmissions Database from 2010 to 2014 was queried using the ICD-9 codes for VT (427.1) and catheter ablation (37.34) to identify study population. Incidence, causes of 30-day readmission, in-hospital complications as well as predictors of 30-day readmissions, complications, and cost of care were analyzed. RESULTS: Among 11 725 patients who survived to discharge after index admission for VT ablation, 1911 (16.3%) were readmitted within 30 days. Paroxysmal VT was the most common cause of 30-day readmission (39.51%). Dyslipidemia, chronic kidney disease (CKD), previous CABG, congestive heart failure (CHF), chronic pulmonary disease, and anemia predicted increased risk of 30-day readmissions. The overall in-hospital complication rate was 8.2% with vascular and cardiac complications being the most common. Co-existing CKD and CHF and the need for mechanical circulatory support (MCS) predicted higher complication rates. Similarly increasing age, CKD, CHF, anemia, in-hospital use of MCS or left heart catheterization, teaching hospital, and disposition to nursing facilities predicted higher cost. CONCLUSION: Approximately one in six patients was readmitted after VT ablation, with paroxysmal VT being the most common cause of the readmission. A complication rate of 8.2% was noted. We also identified a predictive model for increased risk of readmission, complication, and factors influencing the cost of care that can be utilized to improve the outcomes related to VT ablation.

Frequency of 30-day readmission and its causes after percutaneous coronary intervention in acute myocardial infarction complicated by cardiogenic shock.

BACKGROUND: Survival after percutaneous coronary intervention (PCI) in acute myocardial infarction complicated by cardiogenic shock (AMI-CS) has increased over the years. Short-term readmission rates in this high-risk population remain unknown. METHODS: We queried the United States (U.S.) Nationwide Readmission Database (NRD) from January 2010 to November 2014 using the International Classification of Diseases-Ninth edition, Clinical Modification (ICD-9 CM) codes to identify all patients ≥18 years readmitted within 30 days after surviving an index hospitalization for PCI in AMI-CS. Incidence, etiologies, and predictors of 30-day readmission were analyzed. RESULTS: Among 46,435 patients who survived to discharge after PCI in AMI-CS, 9,020 (19.4%) were readmitted within 30 days. Median time to 30-day readmission was 11 days. Cardiac conditions were the most common causes of readmission (57.8%). Heart failure was the leading readmission diagnosis (24.8%). Private insurance including HMO and self-pay were predictive of lower 30-day readmission. Among other covariates, female sex, comorbidities such as heart failure, atrial fibrillation, in-hospital complications such as major bleeding, sepsis, respiratory complications, AKI requiring dialysis, utilization of mechanical circulatory support (IABP and ECMO) were independently predictive of 30-day readmission. Trend analysis showed decline in 30-day readmission rates from 21.9% in 2010 to 17.9% in 2014 (ptrend < 0.001). CONCLUSION: In this large real-world database, one in five patients receiving PCI in AMI-CS was readmitted within 30 days after discharge. Cardiac conditions were the most common causes of readmission. Insurance type had significant influence on 30-day readmission.

Etiologies, trends, and predictors of readmission in ST-elevation myocardial infarction patients undergoing multivessel percutaneous coronary intervention.

BACKGROUND: Recent trials have shown benefits with percutaneous coronary intervention (PCI) on nonculprit coronary vessels in select ST-elevation myocardial infarction (STEMI) patients with multivessel coronary artery disease (CAD). However, readmission rates and causes in this high-risk group are unknown. Objective of this study is to explore pattern, causes and factors associated with 30-day readmission after multivessel PCI in STEMI patients. METHODS AND RESULTS: Nationwide Readmissions Data (NRD) between 2010 and 2014 was utilized to identify multivessel PCI cases in STEMI patients using appropriate ICD-9 codes. We evaluated 30-day readmission rate and factors associated with 30-day readmission. Hierarchical logistic regression model was used to identify factors associated with 30-day readmission. Among 22,257 STEMI patients who survived to discharge after multivessel PCI, 2,302 (10.3%) were readmitted within 30-days. Subsequent unresolved/aggravated cardiac issues most commonly triggered readmission (62.66%). Among cardiac causes, heart failure and ischemic heart disease were most frequent etiologies. Advancing age (OR: 1.073, 95%CI: 1.026 to 1.122, p = .002), female sex (OR: 1.36, 95%CI: 1.23 to 1.50, p < .001), comorbid conditions like chronic kidney disease (CKD; OR: 1.35, 95%CI: 1.17 to 1.57, p = .001), congestive heart failure (CHF; OR: 1.40, 95%CI: 1.24 to 1.57, p = .04), anemia (OR: 1.16, 95%CI: 1.002 to 1.34, p = .04), and utilization of a mechanical circulatory support (MCS) device (OR: 1.45, 95%CI: 1.19 to 1.77, p < .001) during the index procedure were predictive of subsequent readmission within 30 days. CONCLUSION: In this large nationally representative study, nearly one in 10 patients were readmitted within 30 days from discharge after index admission for multivessel PCI in STEMI, most commonly for cardiac causes.

Gitelmans Syndrome- A Rare Cause of Recurrent Syncope.

Gitelman's syndrome, or congenital hypokalemic hypomagnesemic hypocalciuria with metabolic alkalosis, is widely described as a benign or milder variant of Barter's syndrome. It presents with variable clinical symptoms including tetanic episodes, muscle cramps, muscle paralysis, tingling numbness, perioral tingling sensation, salt craving and nocturia. This milder salt wasting syndrome can rarely cause significant ventricular arrhythmias and even death. Here, we report a case of 59 year old male who presented with history of recurrent syncope. He was found to have recurrent polymorphic VT with persistent hypokalemia and hypomagnesia. After extensive metabolic investigation, he was diagnosed as a case of Gitelman's syndrome. We report this case because of this rare malignant presentation of a seemingly benign syndrome.

Temporal trends of in-hospital complications associated with catheter ablation of atrial fibrillation in the United States: An update from Nationwide Inpatient Sample database (2011-2014).

BACKGROUND: Catheter ablation is widely accepted intervention for atrial fibrillation (AF) refractory to antiarrhythmic drugs, but limited data are available regarding contemporary trends in major complications and in-hospital mortality due to the procedure. This study was aimed at exploring the temporal trends of in-hospital mortality, major complications, and impact of hospital volume on frequency of AF ablation-related outcomes. METHODS: The Nationwide Inpatient Sample database was utilized to identify the AF patients treated with catheter ablation. In-hospital death and common complications including vascular access complications, cardiac perforation and/or tamponade, pneumothorax, stroke, and transient ischemic attack, were identified using International Classification of Disease (ICD-9-CM) codes. RESULT: In-hospital mortality rate of 0.15% and overall complication rate of 5.46% were noted among AF ablation recipients (n = 50,969). Significant increase in complications during study period (relative increase 56.37%, P-trend < 0.001) was observed. Cardiac (2.65%), vascular (1.33%), and neurological (1.05%) complications were most common. On multivariate analysis (odds ratio [OR]; 95% confidence interval [95% CI]; P value), significant predictors of complications were female sex (OR = 1.40; CI = 1.17-1.68; P value < 0.001), high burden of comorbidity as indicated by Charlson Comorbidity Index ≥2 (OR = 2.84; CI = 2.29-3.52; P value < 0.001), and low hospital volume (< 50 procedures). CONCLUSION: Our study noted a decline in AF ablation-related hospitalizations and complications associated with the procedure. These findings largely reflect shifting trends of outpatient performance of the procedure and increasing safety profile due to improved institutional expertise and catheter techniques.

Short-term outcomes of atrial flutter ablation.

BACKGROUND: Understanding the factors associated with early readmissions following atrial flutter (AFL) ablation is critical to reduce the cost and improving the quality of life in AFL patients. METHOD: The study cohort was derived from the national readmission database 2013-2014. International Classification of Diseases, 9th Revision (ICD-9-CM) diagnosis code 427.32 and procedure code 37.34 were used to identify AFL and catheter ablation, respectively. The primary and secondary outcomes were 90-day readmission and complications including in-hospital mortality. Cox proportional regression and hierarchical logistic regression were used to generate the predictors of primary and secondary outcomes respectively. Readmission causes were identified by ICD-9-CM code in primary diagnosis field of readmissions. RESULT: Readmission rate of 18.19% (n = 1,010 with 1,396 readmissions) was noted among AFL patients (n = 5552). Common etiologies for readmission were heart failure (12.23%), atrial fibrillation (11.13%), atrial flutter (8.93%), respiratory complications (9.42%), infections (7.4%), bleeding (7.39%, including GI bleed-4.09% and intracranial bleed-0.79%) and stroke/TIA (1.89%). Multivariate predictors of 90-day readmission (hazard ratio, 95% confidence interval, P value) were preexisting heart failure (1.30, 1.13-1.49, P < 0.001), chronic pulmonary disease (1.37, 1.18-1.58, P < 0.001), anemia (1.23, 1.02-1.49, P = 0.035), malignancy (1.87, 1.40-2.49, P < 0.001), weekend admission compared to weekday admission (1.23, 1.02-1.47, P = 0.029), and length of stay (LOS) ≥5 days (1.39, 1.16-1.65, P < 0.001). Note that 50% of readmissions happened within 30 days of discharge. CONCLUSION: Cardiac etiologies remain the most common reason for the readmission after AFL ablation. Identifying high risk patients, careful discharge planning, and close follow-up postdischarge can potentially reduce readmission rates in AFL ablation patients.

Spirituality and Religiosity and Its Role in Health and Diseases.

Religiosity is a factor involved in the management of health and diseases/patient longevity. This review article uses comprehensive, evidence-based studies to evaluate the nature of religiosity that can be used in clinical studies, thus avoiding contradictory reports which arise from misinterpretation of religiosity. We conclude that religiosity is multidimensional in nature and ultimately associated with inherent protection against diseases and overall better quality of life. However, a number of untouched aspects of religiosity need to be investigated further before we can introduce religiosity in its fully functional form to the realm of health care.

Impact of Glycoprotein IIb/IIIa Inhibitors Use on Outcomes After Lower Extremity Endovascular Interventions From Nationwide Inpatient Sample (2006-2011).

OBJECTIVE: The aim of our study was to study the impact of glycoprotein IIb/IIIa inhibitors (GPI) on in-hospital outcomes. BACKGROUND: There is paucity of data regarding the impact of GPI on the outcomes following peripheral endovascular interventions. METHODS: The study cohort was derived from Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) database between the years 2006 and 2011. Peripheral endovascular interventions and GPI utilization were identified using appropriate ICD-9 Diagnostic and procedural codes. Two-level hierarchical multivariate mixed models were created. The study outcomes were: primary (in-hospital mortality and amputation studied separately) and secondary (composite of in-hospital mortality and postprocedural complications). Hospitalization costs were also assessed. RESULTS: GPI utilization (OR, 95% CI, P-value) was independently predictive of lower amputation rates (0.36, 0.27-0.49, <0.001). There was no significant difference in terms of in-hospital mortality (0.59, 0.31-1.14, P 0.117), although GPI use predicted worse secondary outcomes (1.23, 1.03-1.47, 0.023). Following propensity matching, the amputation rate was lower (3.2% vs. 8%, P < 0.001), while hospitalization costs were higher in the cohort that received GPI ($21,091 ± 404 vs. 19,407 ± 133, P < 0.001). CONCLUSIONS: Multivariate analysis revealed GPI use in peripheral endovascular interventions to be suggestive of an increase in composite end-point of in-hospital mortality and postprocedural complications, no impact on in-hospital mortality alone, significantly lower rate of amputation, and increase in hospitalization costs. © 2016 Wiley Periodicals, Inc.

Does Surgical Repair of Moderate Ischemic Mitral Regurgitation Improve Survival? A Systematic Review.

Mitral regurgitation (MR) is one of the common complications in myocardial infarction (MI) patients. Almost half of the post MI patients have MR (ischemic MR)(17) which is moderate to severe (grade II-IV). Whether there is a mortality benefit of performing mitral valve repair (MVR) along with coronary artery bypass grafting (CABG) in patients with post MI moderate MR remains inconclusive. Literature search was done from PubMed, Google scholar, Ovid, and Medline databases. Studies which included post MI patients with moderate ischemic MR and reported mortality outcomes of performing CABG and MVR were chosen for the systematic review. Our preliminary literature search identified 194 studies, of which 11 studies met our inclusion criteria. Nine studies showed no survival benefit of performing simultaneous MVR and CABG. One study demonstrated survival benefit of performing CABG plus MVR only in the New York Heart Association (NYHA) class III-IV, and one study suggested survival benefit of performing CABG plus MVR as compared to CABG alone in patient with ischemic MR irrespective of preoperative NYHA functional class. Review of current literature showed mixed results in terms of improvement in functional status but failed to show any survival benefit of performing MVR along with CABG. Limitations of studies include small sample size, difference in baseline demographic variables, and short follow-up period which might influence the outcome of the study. Prospective randomized studies are required to establish clear benefit of performing MVR simultaneously with CABG.

Short term outcomes after transcatheter mitral valve repair.

BACKGROUND: Outcome data following transcatheter mitral valve repair (TMVR) with the MITRACLIP® device are scarce outside the pivotal randomized controlled trials. METHODS: The Nationwide Readmission Data base (NRD) was utilized for years 2013-2017 to identify the study population. Thirty-day readmission pattern, in-hospital complications, causes of readmissions, and multivariate predictors for readmission, complications and mortality were explored. RESULTS: We noted a total of 14,647 index admissions related to MITRACLIP of which 48% of procedures were performed at high volume centers (Annual hospital volume ≥ 25). A total of 15% of patients were readmitted within 30 days of discharge most frequently due to cardiac causes. Approximately 33% of patients were discharged within 24 h of the procedure. The in-hospital mortality rate was 2.8% and in-hospital complication rate was 14.6%. The most common complications were cardiac complications (8.2%), bleeding related complications (5.9%) and vascular complications (0.65%). On multivariate modeling, female sex, CHF, Atrial fibrillation, prior PCI, COPD, CKD, transfer to skilled nursing facility, length of stay ≥2 days were associated with a high risk of readmission. Additionally, coagulopathy, chronic kidney disease and lengthier hospital stays were associated with high risk of complication or death. CONCLUSION: The 30-day readmission rate following commercial treatment with the MITRACLIP device is 15%. Half of these admission were from a cardiac etiology. Heart failure, atrial arrhythmias and clip related complications round out the top 3 cardiac reasons for readmission. There was no impact of hospital size, teaching status or case volume on mortality and in hospital complication rates.
