Management of an Iatrogenic Pulmonary Artery Rupture via Balloon Tamponade.

Pulmonary artery rupture is a rare complication of right heart catheterization characterized by a rapid clinical deterioration and high mortality rate. We present the case of an 89-year-old woman with severe symptomatic aortic stenosis who underwent cardiac catheterization prior to aortic valve replacement. The patient had acute cardiopulmonary deterioration due to pulmonary artery rupture at the time of right heart catheterization, that was successfully sealed by balloon tamponade.

The Efficacy of Cardiac Myosin Inhibitors Versus Placebo in Patients With Symptomatic Hypertrophic Cardiomyopathy: A Meta-Analysis and Systematic Review.

We aimed to assess the overall clinical impact of cardiac myosin inhibitors in hypertrophic cardiomyopathy (HCM). We performed a meta-analysis of published trials assessing the effect of cardiac myosin inhibitors (mavacamten and aficamten) on resting and Valsalva left ventricular outflow tract (LVOT) gradients and functional capacity in symptomatic HCM. The co-primary outcomes were mean percent change (mean difference [MD]) from baseline in LVOT gradient at rest and Valsalva LVOT gradient and the proportion of patients achieving New York Heart Association class improvement ≥1. The secondary outcomes included the mean percent change from baseline N-terminal pro-B-type natriuretic peptide, troponin I, and left ventricular ejection fraction (LVEF). A total of 4 studies (all randomized controlled trials, including 3 mavacamten-focused and 1 aficamten-focused trials) involving 463 patients were included in the meta-analysis. Compared with placebo, the cardiac myosin inhibitor group demonstrated statistically significant differences in the baseline percent change in mean LVOT gradient at rest (MD -62.48, confidence interval [CI] -65.44 to -59.51, p <0.00001) and Valsalva LVOT gradient (MD -54.21, CI -66.05 to -42.36, p <0.00001) and the proportion of patients achieving New York Heart Association class improvement ≥1 (odds ratio 3.43, CI 1.90 to 6.20, p <0.0001). Regarding the secondary outcomes, the intervention group demonstrated statistically significant reductions in mean percent change from baseline in N-terminal pro-B-type natriuretic peptide (MD -69.41, CI -87.06 to -51.75, p <0.00001), troponin I (MD, -44.19, CI -50.59 to -37.78, p <0.00001), and LVEF (MD -6.31, CI -10.35, -2.27, p = 0.002). In conclusion, cardiac myosin inhibitors may confer clinical and symptomatic benefits in symptomatic HCM at the possible expense of LVEF. Further trials with large sample sizes are needed to confirm our findings.

Early surgery or conservative management for asymptomatic severe aortic stenosis: Meta-analysis of RECOVERY and AVATAR.

The standard practice for management for asymptomatic severe aortic stenosis with a normal left ventricular systolic function is conservative management with a few exceptions. This practice is challenged by two recent randomized controlled trials (RCT). All the prior data is observational. We performed a meta-analysis of these 2 RCTs to determine if early surgical aortic valve replacement in this patient population is beneficial compared with the standard conservative therapy.

Mortality outcomes and 30-day readmissions associated with coronary artery aneurysms; a National Database Study.

BACKGROUND: The literature on prevalence and outcomes of coronary artery aneurysm (CAA) in the United States (US) is limited. OBJECTIVE: To study the prevalence, outcomes, and trends of CAA. METHODS: Data from the national readmissions database (NRD) sample that constitutes 49.1% of the stratified sample of all hospitals in the US were analyzed for CAA among coronary angiography (CA) related hospitalizations for the years 2012-2018. RESULTS: A total of 6,843,910 index CA related hospitalizations were recorded for the years 2012-2018 in the NRD (Mean age 64.37 ± 13.30 years' 38.6% females). Of these 9671 (0.141%) were CAA, 5092 (52.7%) without-ACS and 4579 (47.3%) with ACS [NSTEMI occurred in 2907(63.5%) and STEMI in 1672(36.5%)]. In-hospital mortality among CAA was comparable to those without-CAA on angiography (n-209,2.17% vs n = 175,120,2.56%;p = 0.08). CAA patients who presented with ACS vs those without ACS had higher mortality (n = 150,3.28%vsn = 60,1.16%;p < 0.001) cardiogenic shock 6.9%vs2%, ventricular arrythmias 9.2%vs5.2%, coronary dissection 58%vs42.7%, and need for mechanical circulatory support 7%vs2.7% respectively. Percutaneous coronary intervention (PCI) was performed among 45.2% patients; however, on coarsened exact matching of baseline characteristics, PCI had no association with mortality, patients (OR 1.22, 95%CI0.69-2.16, p = 0.49). The prevalence of CAA on CA trend towards increased mortality with ACS increased over the years 2012-2018 (linear p-trend <0.05). The 30-day readmissions rate were 13.8% (non-CAA) vs 4.6% (CAA) p = 0.001 predominantly cardiovascular causes (50.9%vs70.7%) and PCI on readmission (7.06%vs17.5%). CONCLUSION: CAA is an uncommon anomaly noted on coronary angiography. The higher mortality in patients with ACS and increasing trend of CAA-ACS warrants more research.

Coronary Artery Aneurysms in ST-Elevation Myocardial Infarction (From a United States Based National Cohort).

This study aimed to study group differences in patients presenting with ST-elevation myocardial infarction (STEMI) based on the presence or absence of associated coronary artery aneurysms (CAA). The cause-and-effect relationship between CAAs and STEMI is largely unknown. The Nationwide Readmission database was used to identify and study group differences of patients with STEMI and with and without CAA from 2014 to 2018. The primary outcome in the 2 groups was mortality. Secondary outcomes in the 2 groups included differences in clinical outcomes, cardiovascular interventions performed, and prevalence of coronary artery dissection. The total number of patients with STEMI included was 1,038,299. In this sample, 1,543 (0.15%) had CAA. Compared with those without CAA, patients with CAAs and STEMI were younger (62.6 vs 65.4), more likely to be male (78 vs 66%), and had a higher prevalence of a history of Kawasaki disease (2.5 vs 0.01%). A difference exists in the prevalence of coronary dissection in patients with STEMI with and without CAA (73% vs 1%). Patients with CAA were more often treated with coronary artery bypass grafting (13.1 vs 5.6%), thrombectomy (16.5 vs 6%), and bare-metal stent implantation (8 vs 4.4). Patients in the CAA STEMI group had lower all-cause mortality (6.3 vs 11.7%). In conclusion, there are important differences in patients with STEMI with and without CAA, which include, but are not limited to, factors such as patient profile, the risk for coronary dissection, treatment, outcomes, and mortality.

Scleroderma hypertensive renal crisis among systemic sclerosis patients: A national emergency department database study.

BACKGROUND: Literature regarding trends for incidence and mortality of scleroderma renal crisis (SRC) in systemic sclerosis (SSc) within the United States (US) emergency departments (EDs) is limited. OBJECTIVE: To study the mortality of SRC among SSc patient encounters within the US EDs. METHODS: Data from the National Emergency Department Sample (NEDS) constitutes 20% sample of hospital-owned EDs and inpatient sample in the US were analyzed for SSc with and without SRC using ICD-9 codes. A linear p-trend was used to assess the trends. RESULTS: Of the total 180,435 encounters with the diagnosis of SSc in NEDS for the years 2009 2014, 771 or 4.27/1000 patients (mean age 59.6 ± 15.5 years, 75.4% females) were recorded with SRC. The numerical differences in mortality among SRC (32 or 4.1%) and non-SRC subgroups (5487 or 3.1%) did not reach statistical significance (p = 0.3). Major complications among SRC in comparison to non-SRC subgroup include ischemic stroke (5.6% vs 0.98%, p = 0.001), new-onset AF (8% vs 6.9%, p = 0.001), new-onset congestive heart failure (24.1% vs 8.8%, p = 0.001), pulmonary arterial hypertension (15.8% vs 10.9%, p = 0.001), respiratory failure (27.5% vs 10.5%, p = 0.001), and deep vein thrombosis (4.7% vs 4.6%, p = 0.001). Congestive heart failure (CHF) was strongly associated with SRC among SSc (OR 4.3 95%CI 2.7-6.7; p < 0.001). The absolute yearly rate of SRC had increased over the study years from 2.11/1000 to 5.79/1000 (linear p-trend 0.002) while the mortality trend remained steady. CONCLUSION: SRC is a relatively rare medical emergency. Although there has been a significant rise in the rate of SRC among SSc patients over the study years, mortality rates had remained steady. SSc patients with CHF should be considered to have low threshold for admission to inpatient services from EDs.

Home Health Care Utilization Trend, Predictors, and Association With Early Rehospitalization Following Endovascular Transcatheter Aortic Valve Replacement.

BACKGROUND/PURPOSE: Home healthcare (HHC) utilization is associated with higher rates of rehospitalization in patients with heart failure and transcatheter mitral valve repair. This study sought to assess the utilization, predictors, and the association of HHC with 30-day readmission in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS/MATERIALS: We queried the Nationwide Readmission Database from January 2012 to December 2017 for TAVR discharges with and without HHC referral. Using multivariate analysis, we identified predictors of HHC utilization, and its association with outcomes. RESULTS: Of 60,950 TAVR discharges, 21,724 (35.7%) had HHC referral. On multivariable analysis, female sex (OR, 1.34; 95% CI, 1.29-1.40), non-elective admission (OR, 1.49; 95% CI, 1.42-1.56), diabetes mellitus (OR, 1.09; 95% CI, 1.05-1.13), prior stroke (OR, 1.06; 95% CI, 1.01-1.12), anemia (OR, 1.16; 95% CI, 1.11-1.21), and in-hospital complications including cardiogenic shock (OR, 1.37; 95% CI, 1.16-1.50), cardiac arrest (OR, 1.22; 95% CI, 1.00-1.50), stroke (OR, 2.62; 95% CI, 2.20-3.18), and new Permanent pacemaker (OR, 1.49; 95% CI, 1.41-1.58) were identified as independent predictors of HHC referral. HHC utilization was associated with longer median length of stay (4 days vs. 2 days, P < 0.001), higher rate of 30-day all-cause (15.5% vs. 10.6%, P < 0.001) and heart failure (2.1%vs. 1.1%, P < 0.001) readmission rates compared to those without HHC. CONCLUSIONS: Our study identified a vulnerable group of TAVR patients that are at higher risk of 30-day readmission. Evidence-based interventions proven effective in reducing the burden of readmissions should be pursed in these patients to improve outcomes and quality of life.

In-hospital outcomes of COVID-19 infection in patients with underlying cardiovascular disease.

BACKGROUND: The effects of cardiovascular comorbidities on outcomes in COVID-19 hospitalized patients has not been well studied. METHODS: This is a hospital-based study evaluating the effects of CVD on the outcomes in patients admitted with COVID-19. Clinical outcomes were studied in patients with and without CVD. RESULTS: Eighty-seven patients had CVD, and 193 patients had no history of CVD. Ischemic heart disease was the most common CVD (63%). When compared with patients with no CVD, those with CVD had higher mortality (29% vs 9%, p < 0.001), discharge to a skilled nursing facility (SNF) (36% vs 15%, p < 0.001), and change of code status to 'do not resuscitate' (41% vs 14%, p < 0.001). The odds for mortality were high with ischemic heart disease (OR 3.6, 95% CI 1.8-7.3, p < 0.001), and systolic heart failure (OR 3.8,95% CI 1.2-12.3, p = 0.02). Patients in the CVD group were more likely to have incident atrial fibrillation (22% vs 3%, p < 0.001), type 2 Mi (17% vs 6%, p = 0.002), high BNP (57% vs 14%, p < 0.001), acute kidney injury (64% vs 29%, p < 0.001), and any type of circulatory shock (27% vs 12%, p = 0.001). CONCLUSION: CVD is associated with increased mortality, myocardial injury, arrhythmias, and discharges to an SNF.

Long-term outcomes of ischemic post-conditioning primary PCI and conventional primary PCI in acute STEMI: a meta-analysis of randomized trials.

BACKGROUND: Data regarding ischemic postconditioning during percutaneous coronary intervention (PCI) as compared conventional PCI alone has yielded conflicting results. METHODS: Online databases comparing use of ischemic postconditioning percutaneous coronary intervention (ICP-PPCI) in STEMI patients with conventional PPCI were selected. Mortality, heart failure (HF), myocardial infarction (MI), and major adverse cardiac events (MACE) were evaluated. The primary outcome was composite of HF, MI, and mortality. Pooled risk ratio (RR) with 95% confidence interval (CI) were computed using random-effects model. RESULTS: Eight studies consisting of 2,566 patients (ICP-PPCI n = 1,228; PPCI n = 1,278) were included. The mean age for PPCI group was 61.38 ± 7.86 years (51% men) and for PCI 59.83 ± 8.94 years (47% men). There were no differences in outcome between ICP-PPCI and PPCI in terms of HF (RR 0.87 95% CI0.51-1.48; p = 0.29), MI (RR 1.28, 95%CI0.74-2.20; p = 0.20), mortality (RR 0.93, 95%CI0.64-1.34; p = 0.58), and MACE (RR 0.89, 95%CI0.74-1.07; p = 0.22). The results for composite event for the ICP-PPCI and PPIC procedures, at ≥1 year follow-up duration, were comparable (RR 1.00 95%CI0.82-1.22; p = 1). CONCLUSION: Ischemic postconditioning post percutaneous coronary intervention in STEMI patients has no long-term benefits over conventional PCI.

Cryoablation versus antiarrhythmic therapy for initial treatment of atrial fibrillation: a systematic review and meta-analysis.

BACKGROUND: Atrial fibrillation is a common cardiac arrhythmia that affects approximately 2% of the overall population. Current guidelines suggest the use of antiarrhythmic agents as initial therapy in patients with symptomatic atrial fibrillation; however, using cryoablation as a first-line therapy might provide increased efficacy. METHODS: We conducted a systematic review from inception to March 2021 to find randomized controlled trials (RCT) that directly compared cryoablation therapy versus antiarrhythmic therapy as initial treatment for atrial fibrillation. RESULTS: The primary outcome of our meta-analysis was recurrence of atrial arrhythmias. The secondary outcome evaluated serious adverse events of each therapy. Three RCTs involving 724 patients were included in the meta-analysis. The results showed a statistically significant reduction in recurrence of atrial arrhythmias in patients receiving cryoablation compared to antiarrhythmic therapy [RR 0.60, 95% CI (0.50, 0.72), P < 0.00001, I2 = 0%]. There was no significant difference in serious adverse events between patients receiving cryoablation compared to patients receiving antiarrhythmic therapy [RR 0.80, 95% CI (0.57, 1.13), P = 0.21, I2 = 0%]. CONCLUSION: Our meta-analysis showed that cryoablation therapy as initial therapy is more efficacious than antiarrhythmic therapy in patients with atrial fibrillation without an increased risk of serious adverse events.

Transradial versus transfemoral access for cardiac catheterization: a nationwide pilot study of training preferences and expertise in The United States.

BACKGROUND: The objective was to assess current training preferences, expertise, and comfort with transfemoral access (TFA) and transradial access (TRA) amongst cardiovascular training fellows and teaching faculty in the United States. As TRA continues to dominate the field of interventional cardiology, there is a concern that trainees may become less proficient with the femoral approach. METHODS: A detailed questionnaire was sent out to academic General Cardiovascular and Interventional Cardiology training programs in the United States. Responses were sought from fellows-in-training and faculty regarding preferences and practice of TFA and TRA. Answers were analyzed for significant differences between trainees and trainers. RESULTS: A total of 125 respondents (75 fellows-in-training and 50 faculty) completed and returned the survey. The average grade of comfort for TFA, on a scale of 0 to 10 (10 being most comfortable), was reported to be 6 by fellows-in-training and 10 by teaching faculty (p < 0.001). TRA was the first preference in 95% of the fellows-in-training compared to 69% of teaching faculty (p 0.001). While 62% of fellows believed that they would receive the same level of training as their trainers by the time they graduate, only 35% of their trainers believed so (p 0.004). CONCLUSION: The shift from TFA to radial first has resulted in significant concern among cardiovascular fellows-in training and the faculty regarding training in TFA. Cardiovascular training programs must be cognizant of this issue and should devise methods to assure optimal training of fellows in gaining TFA and managing femoral access-related complications.

Bioresorbable polymer and durable polymer metallic stents in coronary artery disease: a meta-analysis.

BACKGROUND: Literature on bioresorbable-polymer-stents (BPS) and second-generation durable-polymer-stents (DPS) in percutaneous coronary intervention (PCI) for all comer CAD is conflicting. METHODS: Randomized controlled studies comparing PCI among BPS and second-generation DPS were identified up until May-2020 from online databases.  Primary outcomes included are all-cause myocardial infarction (MI), cardiac-death, target-vessel-revascularization (TVR), target-vessel MI (TVMI), and stent-thrombosis (ST). Random effect method of risk ratio and confidence interval of 95% was used. RESULTS: 25 prospective randomized controlled trials with 31,822 patients (BPS n = 17,065 and DPS n = 14,757) were included in the study. Follow-up ranged between a minimum of 6 months to more than 5 years. Cardiac death (RR 1.02, 95% CI 0.89-1.45, p = 0.16) was comparable in BPS and second-generation DPS. Risk of all-cause MI was similar between BPS and DPS (RR 0.97, 95% CI 0.84-1.11, p = 0.73). TVMI (RR 0.88, 95% CI 0.69-1.11, p = 0.33) and ST rates were also comparable in BPS and DPS groups (RR 1.06, 95% CI 0.80-1.40, p = 1.00). Overall TVR had comparable outcomes between BPS and DPS (RR 0.95, 95% CI 0.79-1.14, p < 0.001); however, higher TVR was seen among BPS group at follow-up of ≥5 years (RR 1.39, 95% CI 1.12-1.14, p = 0.02). Bias was low and heterogeneity was moderate. CONCLUSION: Patients undergoing PCI treated with BPS had comparable outcomes in terms of cardiac death, TVR, ST, TVMI, and all-cause MI to patients treated with second-generation DPS; however, BPS had higher rates of TVR for follow-up of ≥5-years.

Coronavirus disease 2019 (COVID-19) and QTc prolongation.

INTRODUCTION: The cause-and-effect relationship of QTc prolongation in Coronavirus disease 2019 (COVID-19) patients has not been studied well. OBJECTIVE: We attempt to better understand the relationship of QTc prolongation in COVID-19 patients in this study. METHODS: This is a retrospective, hospital-based, observational study. All patients with normal baseline QTc interval who were hospitalized with the diagnosis of COVID-19 infection at two hospitals in Ohio, USA were included in this study. RESULTS: Sixty-nine patients had QTc prolongation, and 210 patients continued to have normal QTc during hospitalization. The baseline QTc intervals were comparable in the two groups. Patients with QTc prolongation were older (mean age 67 vs. 60, P 0.003), more likely to have underlying cardiovascular disease (48% versus 26%, P 0.001), ischemic heart disease (29% versus 17%, P 0.026), congestive heart failure with preserved ejection fraction (16% versus 8%, P 0.042), chronic kidney disease (23% versus 10%, P 0.005), and end-stage renal disease (12% versus 1%, P < 0.001). Patients with QTc prolongation were more likely to have received hydroxychloroquine (75% versus 59%, P 0.018), azithromycin (18% vs. 14%, P 0.034), a combination of hydroxychloroquine and azithromycin (29% vs 7%, P < 0.001), more than 1 QT prolonging agents (59% vs. 32%, P < 0.001). Patients who were on angiotensin-converting enzyme inhibitors (ACEi) were less likely to develop QTc prolongation (11% versus 26%, P 0.014). QTc prolongation was not associated with increased ventricular arrhythmias or mortality. CONCLUSION: Older age, ESRD, underlying cardiovascular disease, potential virus mediated cardiac injury, and drugs like hydroxychloroquine/azithromycin, contribute to QTc prolongation in COVID-19 patients. The role of ACEi in preventing QTc prolongation in COVID-19 patients needs to be studied further.

Post-PCI outcomes in STEMI patients with coronary ectasia: meta-analysis.

BACKGROUND: Coronary ectasia (CE) is defined as dilation of the coronary artery, 1.5 times that of the surrounding vessel. Outcomes of percutaneous intervention (PCI) in patients with CE presenting as ST-elevated myocardial infarction (STEMI) remain a topic of debate. METHODS: Studies comparing outcomes of PCI in CE versus no-ectasia (NE) STEMI patients were identified. Baseline angiographic characteristics include thrombolysis in myocardial infarction (TIMI) 0-1 flow, right coronary artery (RCA) involvement, and primary outcomes including thrombus aspiration, no-reflow, mortality, and TIMI-3 post-PCI. Odds ratio (OR) and 95% confidence interval (CI) were calculated. RESULTS: Six studies (n = 5746, CE-340 and NE-5406) qualified for the analysis. RCA involvement was more common in CE than NE, OR-1.39 (95%CI1.06-1.82, p-0.02). Pre-procedure TIMI-0-1 was of comparable results between the groups (p-1.13). Higher thrombus aspiration for CE (OR 2.18, 95%CI1.44-3.32;p-<0.001). CE had higher incidence of no-reflow (OR 4.07, 95%CI2.42-6.84;p-<0.001). TIMI-3 flow post-PCI was achieved less commonly in the CE group (OR-0.64, 95%CI-0.48-0.86;p-<0.001). Mortality on follow-up was comparable (0.83, 95%CI0.39-1.78;p-0.63). Metaregression analysis did not show confounding effects from comorbidities. CONCLUSION: Coronary ectasia patients with STEMI had higher rates of PCI failure and no-reflow than NE; however, mortality during follow-up was comparable.

Myocardial injury in hospitalized COVID-19 patients: a retrospective study, systematic review, and meta-analysis.

INTRODUCTION: The majority of studies evaluating the effect of myocardial injury on the survival of COVID-19 patients have been performed outside of the United States (U.S.). These studies have often utilized definitions of myocardial injury that are not guideline-based and thus, not applicable to the U.S. METHODS: The current study is a two-part investigation of the effect of myocardial injury on the clinical outcome of patients hospitalized with COVID-19. The first part is a retrospective analysis of 268 patients admitted to our healthcare system in Toledo, Ohio, U.S.; the second part is a systematic review and meta-analysis of all similar studies performed within the U.S. RESULTS: In our retrospective analysis, patients with myocardial injury were older (mean age 73 vs. 59 years, P 0.001), more likely to have hypertension (86% vs. 67%, P 0.005), underlying cardiovascular disease (57% vs. 24%, P 0.001), and chronic kidney disease (26% vs. 10%, P 0.004). Myocardial injury was also associated with a lower likelihood of discharge to home (35% vs. 69%, P 0.001), and a higher likelihood of death (33% vs. 10%, P 0.001), acute kidney injury (74% vs. 30%, P 0.001), and circulatory shock (33% vs. 12%, P 0.001). Our meta-analysis included 12,577 patients from 8 U.S. states and 55 hospitals who were hospitalized with COVID-19, with the finding that myocardial injury was significantly associated with increased mortality (HR 2.43, CI 2.28-3.6, P 0.0005). The prevalence of myocardial injury ranged from 9.2 to 51%, with a mean prevalence of 27.2%. CONCLUSION: Hospitalized COVID-19 patients in the U.S. have a high prevalence of myocardial injury, which was associated with poorer survival and outcomes.

Drug-Eluting Stents Versus Bare-Metal Stents in Large Coronary Artery Revascularization: Systematic Review and Meta-Analysis.

OBJECTIVES: We aim to determine if drug eluting stents (DES) are better than bare-metal stents (BMS) in large coronary artery (diameter ≥ 3 mm) percutaneous coronary intervention (PCI). BACKGROUND: DES have become the standard of care for PCI in coronary artery disease (CAD). However, the superiority of DES over BMS in large vessel CAD is not clear and previous studies have shown conflicting results. METHODS: Randomized controlled trials (RCTs) comparing outcomes of PCI with BMS and DES for large vessel CAD were identified from the year 2000 to August 2019. The outcomes were studied individually and included all-cause mortality, myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis. Aggregated odds ratio and 95% CI were calculated using a random-effects model. RESULTS: Eight RCTs were included (4 with data for first-generation DES, 3 with data for second-generation DES, and 1 with data for both first- and second-generation DES). Compared to BMS, second generation DES had a significantly lower rate of all-cause mortality (2.4% vs. 3.9%, OR 0.74, 95% CI 0.56-0.98, P 0.04), TLR (3.5% vs. 8.6% OR 0.38 95% CI 0.28-0.53, P < 0.001), and MI (2.1% vs. 2.9% OR 0.73 95% CI 0.53-1.0, P 0.05). The difference in all-cause mortality was not seen with first-generation DES. CONCLUSION: Newer DES are associated with a lower mortality, TLR, and MI and thus should be preferred over BMS for large coronary artery PCI.
