RESUMEN
Calcified coronary artery bifurcation lesions (CBL) remain a challenge for the interventional cardiologist. Evidence regarding treatment of CBL is minimal. Optimal plaque modification is the most important step prior to stent deployment. Provisional stenting is the preferred strategy for most bifurcation lesions. However, two-stent strategy should be considered for BL with compromised large SB (>2.5 mm) supplying a large territory, >70% SB stenosis and lesions more than 5 mm long. In this contemporary review article, we present a simplified approach to treating CBL and demonstrate the approach to specific case examples using our newly developed mobile application, BifurcAID.

BACKGROUND: Selection of an appropriate antithrombotic regimen in patients requiring oral anticoagulation (OAC) undergoing percutaneous coronary intervention (PCI) still remains a challenge. An ideal 9-2regimen should balance the risk of bleeding against ischemic benefit. METHODS: A comprehensive literature search for studies comparing triple antithrombotic therapy (TAT) vs double antithrombotic therapy (DAT) in patients requiring OAC undergoing PCI was performed in clinicalTrials.gov, PubMed, Web of Science, EBSCO Services, Cochrane Central Register of Controlled Trials, Google Scholar, and various scientific conference sessions from inception to May 1st, 2019. A meta-analysis was performed using random-effects model to calculate risk ratio (RR) and 95% confidence interval (CI). RESULTS: Fifteen studies were eligible and included 13 967 patients, of which 7349 received TAT and 6618 received DAT. Compared with DAT, TAT was associated with lower risk of myocardial infarction (RR, 0.82; 95%CI, 0.69-0.98; P = .03) and stent thrombosis (RR, 0.66; 95%CI, 0.46-0.96; P = .03). There was no difference in risk of trial defined major adverse cardiac events, all-cause mortality, and stroke between two groups. Compared with DAT, TAT was associated with higher risk of trial defined major bleeding (RR, 1.67; 95%CI, 1.38-2.01; P < .00001), including thrombolysis in myocardial infarction major bleeding (RR, 1.81; 95%CI, 1.47-2.24; P < .00001) but no significant difference in risk of intracranial bleeding. CONCLUSION: In patients requiring OAC undergoing PCI, TAT was associated with a lower risk of myocardial infarction but with a significantly higher risk of major bleeding when compared with DAT.

Acute myocardial infarction (AMI) during pregnancy is rare but fatal complication. Recent incidence of pregnancy related AMI and trends in the related outcomes are unknown. The Nationwide Inpatient Sample database was utilized from years 2005 to 2014. International Classification of Disease-Ninth Revision were used to identify pregnancy related admissions and AMI. Primary outcome was incidence and trend of AMI related to pregnancy and Secondary outcomes were trends in mortality, resource utilization, and predictors of AMI during pregnancy. Simple logistic regression model was used to calculate predictors of AMI during pregnancy. p Values for trends were generated by Cochrane-Armitage test for categorical variables and simple linear regression for continuous variables. A total of 43,437,621 pregnancy related hospitalization and 3,786 cases of AMI (86% ante-partum and 14% postpartum) were noted during study period. The incidence of AMI during the study period was 8.7 per 100,000 pregnancies with an overall increase in incidence during the study period (relative increase of 18.9%, p <0.001). There was a concomitant decrease in mortality (relative decrease of 40.05%, p <0.001), cost of care (relative decrease of 8.70%, p <0.001), and length of stay (relative decrease of 13.53%, p <0.001). Significant predictors of AMI during pregnancy were higher age of pregnancy, black race, co-morbidities such as hypertension, thrombophilia, diabetes milletus, substance abuse, smoking, hyperlipidemia, heart failure, deep venous thrombosis, transfusion, fluid and electrolyte imbalance, and postpartum complications such as hemorrhage, infection, and depression. In conclusion, the incidence of AMI 2005 to 2014 rose with a concomitant decrease in mortality and resource utilization. High-risk patient characteristics were identified which could be utilized for resource allocation to further improve outcomes.

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.

BACKGROUND: Pulseless ventricular tachycardia/ventricular fibrillation (VT/VF) is the initial rhythm in a third of in-hospital cardiac arrest patients. Mechanical circulatory support (MCS) device use remains poorly understood in this population. METHODS: We conducted an observational analysis of temporal trends in the utilization of MCS in VT/VF IHCA between January 2008 and December 2014 utilizing the Nationwide Inpatient Sample (NIS) database. Using multivariable analysis, we assessed factors associated with MCS use and survival to discharge. RESULTS: Among 151,628 hospitalizations with VT/VF IHCA, 14,981 (9.9%) received MCS. Intra-aortic balloon pump (IABP) was the most commonly used MCS (9.1%). From 2008 to 2014, there was significant increase in the utilization of MCS (8.7-11%; ptrend < 0.0001). On multivariable analysis, there was 12-fold increase and three-fold increase in the utilization of PVAD and ECMO respectively; however, there was no significant change in the use of IABP. Over the seven-year sample period, there was significant increase in the overall survival to hospital discharge (35.4-43.5%; ptrend < 0.0001). Survival to hospital discharge increased in both MCS and non-MCS groups. CONCLUSION: There was significant increase in utilization of MCS after VT/VF IHCA during the study period. IABP was the most commonly utilized MCS. The survival to hospital discharge increased in the overall study population including both MCS and non-MCS groups. Future studies are needed to identify patient population most likely to benefit from the use of MCS after VT/VF IHCA.

Endovascular aneurysm intervention (EVAI) is one of the most commonly performed vascular interventions for abdominal aortic aneurysm (AAA). Data regarding 30-day readmission rates after EVAI are poorly reported in the literature. We used the United States Nationwide Readmission Database from 2010 to 2014 to identify all patients ≥18 years who were readmitted within 30 days after a hospital discharge for EVAI of the AAA. Incidence, etiologies, predictors of 30-day readmission, and trends of readmission rates were analyzed. In 138,014 patients who survived to discharge after an EVAI procedure for AAA, 14,146 (10.24%) were readmitted within 30 days. Median time to readmission was 11 days. Cardiac causes (16.34%) followed by infections (15.40%) and vascular complications (12.86%) were common etiologies of readmission. Greater patient age, female sex, coexisting co-morbidities such as heart failure, atrial fibrillation, peripheral vascular disease, lung disease, and chronic kidney disease were independent predictors of 30-day readmission. In-hospital complications during an index admission such as major bleeding or vascular complications were also predictive of 30-day readmission. Trend analysis showed a progressive decline in readmission rates from 11.3% in 2010 to 9.6% in 2014 (ptrend <0.0001), 20% lower odds in 2014 compared with 2010 (odds ratio 0.80, 95% confidence interval 0.72 to 0.87, p <0.0001). In this contemporary study of EVAI for AAA, nearly 1 in 10 patients was readmitted within 30 days of discharge after an index admission. Cardiac complications and infections were common causes of readmission within 30 days.

Background Percutaneous coronary intervention with drug-eluting stents (DES) has been increasingly used for revascularization of saphenous vein graft stenosis without strong clinical evidence favoring their use. Randomized controlled trials comparing DES versus bare-metal stents (BMS) in saphenous vein graft-percutaneous coronary intervention have been inconclusive. Methods and Results We performed a comprehensive literature search through May 15, 2018, for all eligible studies comparing DES versus BMS in patients with saphenous vein graft stenosis in PubMed, EMBASE, SCOPUS, Google Scholar, and ClinicalTrials.gov. Clinical outcomes included all-cause mortality, cardiovascular mortality, major adverse cardiovascular events, myocardial infarction, stent thrombosis, and target vessel revascularization. Six randomized controlled trials were eligible and included 1582 patients, of whom 797 received DES and 785 received BMS. The follow-up period ranged from 18 months to 60 months. There was no statistically significant difference between DES and BMS for all-cause mortality (risk ratio [RR],1.11; 95% CI, 0.0.77-1.62; P=0.57), cardiovascular mortality (RR, 1.00; 95% CI, 0.64-1.57; P=0.99), major adverse cardiovascular events (RR, 0.83; 95% CI, 0.63-1.10; P=20), target vessel revascularization (RR, 0.73; 95% CI, 0.48-1.11; P=0.14), myocardial infarction (RR, 0.74; 95% CI, 0.48-1.16; P=0.19), or stent thrombosis (RR, 1.06; 95% CI, 0.42-2.65; P=0.90). Conclusions In patients undergoing percutaneous coronary intervention for saphenous vein graft lesions, our results showed that there was no significant difference between DES and BMS for mortality, major adverse cardiovascular events, target vessel revascularization, myocardial infarction, or stent thrombosis.

Percutaneous ventricular assist devices (PVAD) have been used at an increasing rate in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). Recent evidence has demonstrated that use of invasive hemodynamic monitoring with right-sided heart catheterization (RHC) was associated with improved survival in recipients of PVAD in AMI-CS. We sought to examine the utilization of RHC in patients receiving PVAD in AMI-CS. We queried the Nationwide Inpatient Sample database from 2008 to 2014 and identified patients using ICD-9-CM codes for AMI-CS (410, 785.51), PVAD (37.68), and RHC (37.21, 37.23). Temporal trends were analyzed using Cochrane Armitage test. In 5,925 patients who were treated with PVAD for AMI-CS, 1,691 (28.5%) underwent RHC. The mean (SD) age was 63.9 (12.3) years; majority were males (72.8%) and white (63.3%). Patients receiving RHC had higher baseline burden of co-morbidities, Charlson Co-morbidity Index ≥2 (56.1%). From 2008 to 2014, there was decrease in the utilization of RHC in patients receiving PVAD from 40.4% to 29.8% (ptrendâ¯=â¯0.0005). Mortality decreased in patients who received RHC (56% to 42.6%, ptrendâ¯=â¯0.005), whereas mortality increased in patients without RHC (44.4% to 48.4%, ptrendâ¯=â¯0.001). In conclusion, in patients who present with AMI-CS and were treated with PVAD, there was a progressive decline in the utilization of RHC, despite a temporal decrease in mortality in patients receiving RHC. Novel strategies should be explored to increase the use of RHC in this high-risk patient population.

BACKGROUND: The incidence of patients with previous history of coronary artery bypass grafting (CABG) presenting for aortic valvular replacement has been consistently on the rise. Repeat sternotomy for surgical aortic valve replacement (SAVR) carries an inherent risk of morbidity and mortality when compared to Transcatheter aortic valve replacement (TAVR). METHODS: The Nationwide inpatient sample (NIS) from 2012 to 2014 was queried using the International Classification of Diseases-Ninth edition, Clinical Modification (ICD-9-CM) codes to identify all patients ≥ 18 years with prior CABG who underwent TAVR (35.05 and 35.06) or SAVR (35.21 and 35.22). Propensity score matching (1:1) was performed and in-hospital outcomes were compared between matched cohorts. RESULTS: From 2012 to 2014, there was progressive increase in the annual number of TAVR procedures from 1485 to 4020, with a decrease in patients undergoing SAVR from 2330 to 1955 (Ptrend < 0.0001) in the above population. There was no significant difference in in-hospital mortality rates. Compared to SAVR, TAVR was associated with lower risk of stroke (1.2% vs. 3.3%, P = 0.009), AKI (12.9% vs. 21.3%, P < 0.0001), myocardial infarction (0.9% vs. 2.7%, P = 0.01) and major bleeding (9.1% vs. 25.1%, P < 0.0001). TAVR was associated with higher risk of pacemaker implants (9.6% vs. 4.9%, P = 0.001) and trend toward lower risk of vascular complications (2.3% vs. 4.1%, P = 0.05). CONCLUSION: In this large cohort of patients with previous CABG, there is no significant difference in in-hospital mortality between TAVR and SAVR. TAVR was associated with lower risk of in-hospital outcomes.

BACKGROUND: The utilization of cardiac resynchronization therapy defibrillator (CRT-D) has increased significantly, since its initial approval for use in selected patients with heart failure. Limited data exist as for current trends in implant-related in-hospital complications and cost utilization. The aim of our study was to examine in-hospital complication rates associated with CRT-D and their trends over the last decade. METHODS AND RESULTS: Using the Nationwide Inpatient Sample, we estimated 378 248 CRT-D procedures from 2003 to 2012. We investigated common complications, including mechanical, cardiovascular, pericardial complications (hemopericardium, cardiac tamponade, or pericardiocentesis), pneumothorax, stroke, vascular complications (consisting of hemorrhage/hematoma, incidents requiring surgical repair, and accidental arterial puncture), and in-hospital deaths described with CRT-D, defining them by the validated International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code. Mechanical complications (5.9%) were the commonest, followed by cardiovascular (3.6%), respiratory failure (2.4%), and pneumothorax (1.5%). Age (≥65 years), female gender (OR, 95% CI; P value) (1.08, 1.03-1.13; 0.001), and the Charlson score ≥3 (1.52, 1.45-1.60; <0.001) were significantly associated with increased mortality/complications. CONCLUSIONS: The overall complication rate in patients undergoing CRT-D has been increasing in the last decade. Age (≥65), female sex, and the Charlson score ≥3 were associated with higher complications. In patients who underwent CRT-D implantation, postoperative complications were associated with significant increases in cost.

BACKGROUND: Bioprosthetic (BP) valves have been increasingly used for aortic valve replacement over the last decade. Due to their limited durability, patients presenting with failed BP valves are rising. Valve in Valve - Transcatheter Aortic Valve Implantation (ViV-TAVI) emerged as an alternative to the gold standard redo-Surgical Aortic Valve Replacement (redo-SAVR). However, the utility of ViV-TAVI is poorly understood. METHODS: A systematic electronic search of the scientific literature was done in PubMed, EMBASE, SCOPUS, Google Scholar, and ClinicalTrials.gov. Only studies which compared the safety and efficacy of ViV-TAVI and redo-SAVR head to head in failed BP valves were included. RESULTS: Six observational studies were eligible and included 594 patients, of whom 255 underwent ViV- TAVI and 339 underwent redo-SAVR. There was no significant difference between ViV-TAVI and redo- SAVR for procedural, 30 day and 1 year mortality rates. ViV-TAVI was associated with lower risk of permanent pacemaker implantation (PPI) (OR: 0.43, CI: 0.21-0.89; P = 0.02) and a trend toward increased risk of paravalvular leak (PVL) (OR: 5.45, CI: 0.94-31.58; P = 0.06). There was no significant difference for stroke, major bleeding, vascular complications and postprocedural aortic valvular gradients more than 20 mm-hg. CONCLUSION: Our results reiterate the safety and feasibility of ViV-TAVI for failed aortic BP valves in patients deemed to be at high risk for surgery. VIV-TAVI was associated with lower risk of permanent pacemaker implantation with a trend toward increased risk of paravalvular leak.

OBJECTIVE: This study sought to examine the trends and predictors of mechanical circulatory support (MCS) use in patients hospitalized after out-of-hospital cardiac arrest (OHCA). BACKGROUND: There is a paucity of data regarding MCS use in patients hospitalized after OHCA. METHODS: We conducted an observational analysis of MCS use in 960,428 patients hospitalized after OHCA between January 2008 and December 2014 in the Nationwide Inpatient Sample database. On multivariable analysis, we also assessed factors associated with MCS use and survival to discharge. RESULTS: Among the 960,428 patients, 51,863 (5.4%) had MCS utilized. Intra-aortic balloon pump (IABP) was the most commonly used MCS after OHCA with frequency of 47,061 (4.9%), followed by extracorporeal membrane oxygenation (ECMO) 3650 (0.4%), and percutaneous ventricular assist devices (PVAD) 3265 (0.3%). From 2008 to 2014, there was an increase in the utilization of MCS from 5% in 2008 to 5.7% in 2014 (P trendâ¯<â¯0.001). There was a non-significant decline in the use of IABP from 4.9% to 4.7% (P trendâ¯=â¯0.95), whereas PVAD use increased from 0.04% to 0.7% (P trendâ¯<â¯0.001), and ECMO use increased from 0.1% to 0.7% (P trendâ¯<â¯0.001) during the study period. Younger, male patients with myocardial infarction, higher co-morbid conditions, VT/VF as initial rhythm, and presentation to a large urban hospital were more likely to receive percutaneous MCS implantation. Survival to discharge was significantly higher in patients who were selected to receive MCS (56.9% vs. 43.1%, OR: 1.16, 95% CI: (1.11-1.21), pâ¯<â¯0.001). CONCLUSIONS: There is a steady increase in the use of MCS in OHCA, especially PVAD and ECMO, despite lack of randomized clinical trial data supporting an improvement in outcomes. More definitive randomized studies are needed to assess accurately the optimal role of MCS in this patient population.

There are sparse comparative data on in-hospital outcomes and readmission rates in patients with acute pulmonary embolism (PE) who receive systemic thrombolytics versus catheter-directed thrombolysis (CDT). The study cohort was derived from the National Readmission Database 2013 to 2014, subset of the Healthcare Cost and Utilization Project sponsored by the Agency for Healthcare Research and Quality. Systemic and CDT were identified using appropriate International Classification of Diseases, 9th Revision, Clinical Modification codes. The co-primary outcomes were in-hospital mortality and 30-day readmissions and secondary outcome was combined in-hospital mortality + gastrointestinal bleed + intracranial hemorrhage. We used propensity score match analysis without replacement using Greedy's algorithm to adjust for possible confounders. We identified a total of 4,426 patients (3,107: systemic thrombolysis and 1,319: CDT) with acute PE who were treated with thrombolysis. In our 2:1 propensity score algorithm, in-hospital mortality was lower in the CDT group (6.12%) versus systemic thrombolytics (14.94%) (odds ratio 0.37, 95% confidence interval 0.28 to 0.49, p <0.001). There was also a lower composite secondary outcome (in-hospital mortality + gastrointestinal bleed + intracranial hemorrhage) in patients who received CDT (8.42%) versus those who received systemic thrombolytics (18.13%) (odds ratio 0.41, 95% confidence interval 0.33 to 0.53, p <0.001). Thirty-day readmission was lower in patients with CDT group (7.65%) compared with systemic thrombolytics (10.58%, p = 0.009). In conclusion, in-hospital mortality, as well as bleeding during primary admission was significantly lower with CDT compared with systemic thrombolytics for patients with acute PE. There was also significant decrease in rate of readmissions among patients receiving CDT compared with systemic thrombolytics.

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.

Aortic stenosis (AS) has an increasing prevalence with age and is commonly associated with hypertension. While it has been established that hypertension is associated with increased mortality in patients with AS, further randomized control trials addressing the use of antihypertensives specifically in patients with AS are needed. The management of hypertension in patients with AS needs a cautious approach due to complex hemodynamic and structural changes involved. Comorbidities like coronary artery disease, heart failure and arrhythmias further dictate management of hypertension in patients with AS. The aim of this article is to review the various agents used in the management of hypertension in patients with AS.
