A Systematic Review and Meta-Analysis of Prevalence, Characteristics, and Impact of Mitral Annular Calcification on Outcomes After Transcatheter Aortic Valve Implantation.

There is a paucity of data on the prognostic impact of mitral annular calcification (MAC) in patients who underwent transcatheter aortic valve implantation (TAVI) with conflicting results being reported by the studies that are published. Therefore, we performed a meta-analysis to assess the short-term and long-term outcomes of MAC in patients after TAVI. Of 25,407 studies identified after the initial database search, 4 observational studies comprising 2,620 patients (2,030 patients in the nonsevere MAC arm and 590 patients in the severe MAC arm) were included in the final analysis. Compared with patients with nonsevere MAC, the severe MAC group was associated with significantly higher incidences of overall bleeding (0.75 [0.57 to 0.98], p = 0.03, I2 = 0%) at 30 days. However, no significant difference was observed between the 2 groups for the rest of the 30-day outcomes: all-cause mortality (0.79 [0.42 to 1.48], p = 0.46, I2 = 9%), myocardial infarction (1.62 [0.37 to 7.04], p = 0.52, I2 = 0%), cerebrovascular accident or stroke (1.22 [0.53 to 2.83], p = 0.64, I2 = 0%), acute kidney injury (1.48 [0.64 to 3.42], p = 0.35, I2 = 0%), and pacemaker implantation (0.70 [0.39 to 1.25], p = 0.23, I2 = 68%). Similarly, follow-up outcomes also showed no significant difference between the 2 groups: all-cause mortality (0.69 [0.46 to 1.03], p = 0.07, I2 = 44%), cardiovascular mortality (0.52 [0.24 to 1.13], p = 0.10, I2 = 70%) and stroke (0.83 [0.41 to 1.69], p = 0.61, I2 = 22%). The sensitivity analysis, however, demonstrated significant results for all-cause mortality (0.57 [0.39 to 0.84], p = 0.005, I2 = 7%) by removing the study by Okuno et al5 and cardiovascular mortality (0.41 [0.21 to 0.82], p = 0.01, I2 = 66%) by removing the study by Lak et al.7 In conclusion, our meta-analysis corroborates the notion that isolated MAC is not an independent predictor of long-term mortality after TAVI and determines severe MAC to be a predictor of mortality at follow-up because of the higher incidence of mitral valve dysfunction associated with it.

Pacing-Related Differences After SAPIEN-3 TAVI: Clinical and Echocardiographic Correlates.

Data regarding the impact of pacing on outcomes after transcatheter aortic valve implantation (TAVI) is evolving especially with regards to pre-existing permanent pacemaker (PPM). We examined the impact of new and previous PPM on the clinical and hemodynamic outcomes after SAPIEN-3 TAVI. We included all consecutive patients who underwent transfemoral TAVI using SAPIEN-3 valve from 2015 to 2018 at our institution. Among 1,028 patients, 10.2% required a new PPM within 30 days, whereas 14% had a pre-existing PPM. The presence of either previous or new PPM had no impact on the 3-year mortality (log-rank p = 0.6) or 1-year major adverse cardiac and cerebrovascular events (log-rank p = 0.65). New PPM was associated with lower left ventricular (LV) ejection fraction (LVEF) at both 30 days (54.4 ± 11.3% vs 58.4 ± 10.1%, p = 0.001) and 1 year (54.2 ± 12% vs 59.1 ± 9.9%, p = 0.009) than no PPM. Similarly, previous PPM was associated with worse LVEF at 30 days (53.6 ± 12.3%, p <0.001) and 1 year (55.5 ± 12.1%, p = 0.006) than no PPM. Interestingly, new PPM was associated with lower 1-year mean gradient (11.4 ± 3.8 vs 12.6 ± 5.6 mm Hg, p = 0.04) and peak gradient (21.3 ± 6.5 vs 24.1 ± 10.4 mm Hg, p = 0.01), despite no baseline differences. Previous PPM was also associated with lower 1-year mean gradient (10.3 ± 4.4 mm Hg, p = 0.001) and peak gradient (19.4 ± 8 mm Hg, p <0.001) and higher Doppler velocity index (0.51 ± 0.12 vs 0.47 ± 0.13, p = 0.039). Moreover, 1-year LV end-systolic volume index was higher with new (23.2 ± 16.1 vs 20 ± 10.8 ml/m2, p = 0.038) and previous PPM (24.5 ± 19.7, p = 0.038) than no PPM. Previous PPM was associated with higher moderate-to-severe tricuspid regurgitation (35.3% vs 17.7%, p <0.001). There were no differences regarding the rest of the studied echocardiographic outcomes at 1 year. In conclusion, new and previous PPM did not affect 3-year mortality or 1-year major adverse cardiac and cerebrovascular events; however, they were associated with worse LVEF, higher 1-year LV end-systolic volume index, and lower mean and peak gradients on follow-up than no PPM.

Clinical and echocardiographic outcomes with new-onset left bundle branch block after SAPIEN-3 transcatheter aortic valve replacement.

BACKGROUND: New-onset left bundle branch block (LBBB) can develop after transcatheter aortic valve replacement (TAVR) resulting in worse outcomes. AIMS: Describe clinical and echocardiographic outcomes with new-onset LBBB after TAVR. METHODS: We included consecutive patients who underwent transfemoral-TAVR with SAPIEN-3 (S3) valve between April 2015 and December 2018. Exclusion criteria included pre-existing LBBB, right BBB, left anterior hemiblock, left posterior hemiblock, wide QRS ≥ 120ms, prior permanent pacemaker (PPM), and nontransfemoral access. RESULTS: Among 612 patients, 11.4% developed new-onset LBBB upon discharge. The length of stay was longer with new-onset LBBB compared with no LBBB [3 (2-5) days versus 2 (1-3) days; p < 0.001]. New-onset LBBB was associated with higher rates of 30-day PPM requirement (18.6% vs. 5.4%; p < 0.001) and 1-year heart failure hospitalizations (10.7% vs. 4.4%; p = 0.033). There was no difference in 3-year mortality between both groups (30.9% vs. 30.6%; p = 0.829). Further, new-onset LBBB was associated with lower left ventricular ejection fraction (LVEF) at both 30 days (55.9 ± 11.4% vs. 59.3 ± 9%; p = 0.026) and 1 year (55 ± 12% vs. 60.1 ± 8.9%; p = 0.002). These changes were still present when we stratified patients according to baseline LVEF (≥50% or <50%). New-onset LBBBs were associated with a higher 1-year LV end-diastolic volume index (51.4 ± 18.6 vs. 46.4 ± 15.1 ml/m2 ; p = 0.036), and LV end-systolic volume index (23.2 ± 14.1 vs. 18.9 ± 9.7 ml/m2 ; p = 0.009). Compared with resolved new-onset LBBB, persistent new-onset LBBB was associated with worse LVEF and higher PPM at 1 year. CONCLUSIONS: New-onset LBBB after S3 TAVR was associated with higher PPM requirement, worse LVEF, higher LV volumes, and increased heart failure hospitalizations, with no difference in mortality.

In-hospital mortality of COVID-19 patients hospitalized with ST-segment elevation myocardial infarction: A meta-analysis.

Introduction: Coronavirus Disease 2019 (COVID-19) has been associated with an increased risk of adverse cardiovascular events including arteriovenous thrombosis, myocarditis and acute myocardial injury. Relevant literature to date has reported widely varying estimates of mortality, ranging from approximately 2 to 11 times higher odds of mortality in COVID-19-positive STEMI (ST-segment elevation myocardial infarction) patients. Hence, we conducted this meta-analysis to resolve these inconsistencies and assess the impact of COVID-19 infection on mortality and other clinical outcomes in patients presenting with STEMI. Methods: This meta-analysis was registered in PROSPERO (CRD42021297458) and performed according to the Cochrane Handbook for Systematic Reviews of Interventions. PubMed and Embase were searched from inception to November 2021 (updated on April 2022) using a search strategy consisting of terms relating to COVID-19, STEMI, and mortality. Results: We identified 435 studies through our initial search. After screening according to our eligibility criteria, a total of 11 studies were included. Compared with the non-COVID-19 STEMI patients, the in-hospital mortality rate was higher in COVID-19-positive STEMI patients. Similarly, the risk of cardiogenic shock was higher in the COVID-19-positive patients. Length of hospital stay was longer in STEMI patients with COVID-19. Conclusions: Our study highlights the necessity for early evaluation of COVID-19 status in all STEMI patients followed by risk stratification, prompt reperfusion and more aggressive management of COVID-19-positive patients. Further research is needed to elucidate the mechanisms behind poorer prognosis in such patients.

Radiation reduction in a modern catheterization laboratory: A single-center experience.

BACKGROUND: Measures were undertaken at the Cleveland Clinic to reduce radiation exposure to patients and personnel working in the catheterization laboratories. We report our experience with these improved systems over a 7-year period in patients undergoing diagnostic catheterization (DC) and percutaneous coronary interventions (PCIs). METHODS: Patients were categorized into preinitiative (2009-2012) and postinitiative (2013-2019) groups in the DC and PCI cohorts. Propensity score matching was done between the pre- and postinitiative groups for both cohorts based on age, sex, body surface area, total fluoroscopy time, and total acquisition time. The effectiveness of radiation reduction measures was assessed by comparing the total air kerma (Ka,r ), and fluoroscopy- and acquisition-mode air kerma in patients in the two groups. RESULTS: In the DC cohort, there was a significant reduction in Ka,r in the postinitiative group in comparison to the preinitiative group (median, 396 vs. 857 mGy; p < 0.001). In the PCI cohort, Ka,r in the postinitiative group was 1265 mGy, which was significantly lower than the corresponding values in the preinitiative group (1994 mGy; p < 0.001). We also observed a significant reduction in fluoroscopy- and acquisition-based air kerma rates, and air kerma area product in the postinitiative group in comparison to the preinitiative group in both matched and unmatched DC and PCI cohorts after the institution of radiation reduction measures. CONCLUSION: There was a significant and sustained reduction in radiation exposure to patients in the catheterization laboratory with the implementation of advanced protocols. Similar algorithms can be applied in other laboratories to achieve a similar reduction in radiation exposure.

Comparison of Outcomes of Transcatheter Aortic Valve Implantation in Patients With Versus Without Mitral Annular Calcium.

There are limited data regarding the impact of mitral annular calcium (MAC) on the outcomes of patients who underwent transcatheter aortic valve implantation (TAVI). We performed a retrospective analysis of patients who underwent TAVI in 2018 and divided them into 2 groups based on the presence or absence of MAC, using a validated MAC computed tomography-based scoring system. Among 468 patients who underwent TAVI in 2018, 271 patients (58%) had MAC present compared with 197 patients (42%) without MAC. Compared with patients without MAC, patients in the MAC group were older (81 vs 79, p = 0.012), had a higher body mass index (29.30 vs 28.05, p = 0.031), lower left ventricular end-diastolic diameter (4.47 vs 4.80, p <0.001), higher mitral valve mean gradient (4.54 vs 3.01, p = 0.031), and a higher Society of Thoracic Surgeons risk score (5.69 vs 4.91, p = 0.127). There was no significant difference in the with versus without MAC groups in the all-cause mortality (at 1 year: 9% vs 6%, p = 0.8; at 2 years: 15% vs 13%, p = 0.47), incidence of myocardial infarction (1% vs 2%, p = 0.417), stroke (1% vs 3%, p = 0.4), and major adverse cardiac and cerebrovascular events (17% vs 19%, p = 0.53) at 1 year. Although the rate of new-onset left bundle branch block was higher in patients with MAC, there was no significant difference between the 2 groups in the rates of complete atrioventricular block (5% vs 3%, p = 0.483) or the need for pacemaker implantation (6% vs 3%, p = 0.168). The post-TAVI peak aortic valve gradient was comparable between the groups with and without MAC (22.52 vs 22.60, p = 0.931). In conclusion, TAVI is a safe alternative for patients with severe aortic stenosis and concomitant MAC, with comparable outcomes to patients without MAC.

Impact of elevated left ventricular filling pressure on long-term outcomes after transcatheter aortic valve replacement.

BACKGROUND: Increase in left ventricular filling pressure (FP) and diastolic dysfunction are established consequences of progressive aortic stenosis (AS). However, the impact of elevated FP as detected by pretranscatheter aortic valve replacement (TAVR) echocardiogram on long-term outcomes after TAVR remains unclear. OBJECTIVE: To understand the impact of elevated FP in patients with severe AS who undergo TAVR. METHODS: This was a retrospective study of all patients who underwent TAVR between 1 January 2014 and 31 December 2017. The presence of elevated FP was determined in accordance with the latest guidelines using the last available comprehensive echocardiogram prior to TAVR. RESULTS: Of 983 patients who were included in our study, 422 patients (43%) were found to have elevated FP and 561 patients (57%) had normal FP prior to TAVR. Patients with elevated FP had a mean age of 81.2±8.6 years and were more likely to be males (62%), diabetic (41% vs 35%, p=0.046), and have a higher prevalence of atrial fibrillation (Afib) (53% vs 39%, p<0.001). The 5-year all-cause mortality after TAVR was significantly higher in patients with elevated FP when compared with patients with normal FP (32% vs 24%, p=0.006). The presence of elevated FP, history of Afib and prior PCI emerged as independent predictors of long-term mortality after TAVR. CONCLUSION: Elevated FP is associated with increased mortality in patients with severe AS undergoing TAVR. Assessment of FP should be incorporated into the risk assessment of AS patients to identify those who may benefit from early intervention.

Mortality in Adult Congenital Heart Disease: Analysis of Outcomes and Risk Stratification.

Adult congenital heart disease (ACHD) is a rising concern for the current healthcare system, with a prevalence that is anticipated to steadily increase through the year 2050. It is estimated that there are >1.4 million adults in the United States living with a congenital heart defect. Despite significant advances in medical and surgical therapy, most of these patients progress to advanced heart failure due to the unique anatomic, physiological, and hemodynamic abnormalities associated with the disease. Patient awareness of the disease coupled with advances in the diagnosis and treatment has led to a significant increase in the surgical treatment of CHD in adults. The authors aim to summarize and critically appraise the current literature on the morbidity, mortality, and risk scores associated with ACHD.

Outcomes of Interventional Management of Coronary Artery Disease in Kidney Transplant Recipients.

BACKGROUND: Cardiovascular disease is the most common cause of death among kidney transplant (KT) recipients. Trials routinely exclude patients with end-stage renal disease when assessing the effect of coronary artery revascularization. We looked to compare long-term outcomes in patients who underwent percutaneous coronary intervention (PCI) before KT with those managed medically. METHODS: We identified all patients who underwent coronary artery catheterization before KT from January 2008 to November 2019 at the Cleveland Clinic. The primary endpoint was all-cause mortality. RESULTS: A total of 272 patients were included, of whom 52 (19.11%) underwent PCI, and the remaining 220 patients were managed medically. The median age in the PCI group was 57.4 years (interquartile range [IQR], 46.9-61.2 years), whereas it was 53.9 years (IQR, 44.6-61 years) in the group medically managed. Baseline characteristics including sex, race, hypertension, diabetes, smoking, and hyperlipidemia were comparable in both groups. The median time to KT was 2.4 years (IQR, 1-5 years) in the PCI group vs 1.2 years (IQR, 0.6-3.3 years) in the medically managed group (P = .001). Among patients who underwent PCI, 40.4% had single vessel disease and 59.6% had multivessel disease compared with 16.8% and 28.6%, respectively, in the medically managed group (P < .001). Overall, there was no difference in mortality in the PCI group compared with the medically managed group after 10 years of follow-up (P = .416). CONCLUSIONS: Patients with coronary artery disease can be safely treated with PCI before KT and have comparable outcomes to those who are managed medically.

Meta-Analysis Comparing Distal Radial Versus Traditional Radial Percutaneous Coronary Intervention or Angiography.

Data comparing outcomes of distal radial (DR) and traditional radial (TR) access of coronary angiography and percutaneous coronary intervention (PCI) are limited. Online databases including Medline and Cochrane Central databases were explored to identify studies that compared DR and TR access for PCI. The primary outcome was the rate of radial artery occlusion (RAO) and access failure. Secondary outcomes included access site hematoma, access site bleeding, access site pain, radial artery spasm, radial artery dissection, and crossover. Unadjusted odds ratios (ORs) with a random-effect model, 95% confidence interval (CI), and p <0.05 were used for statistical significance. Metaregression was performed for 16 studies with 9,973 (DR 4,750 and TR 5,523) patients were included. Compared with TR, DR was associated with lower risk of RAO (OR 0.51, 95% CI 0.29 to 0.90, I2 = 42.6%, p = 0.02). RAO was lower in DR undergoing coronary angiography rather than PCI. Access failure rate (OR 1.77, 95% CI 0.69 to 4.55, I2 87.36%, p = 0.24), access site hematoma (OR 1.11, 95% CI 0.68 to 1.83, I2 0%, p = 0.68), access site pain (OR 2.22, 95% CI 0.28 to 17.38, I2 0%, p = 0.45), access site bleeding (OR 1.11, 95% CI 0.16 to 7.62, I2 85.11%, p = 0.91), radial artery spasm (OR 0.79, 95% CI 0.49 to 1.29, I2 0%, p = 0.35), radial artery dissection (OR 1.63, 95% CI 0.46 to 5.84, I2 0%, p = 0.45), and crossover (OR 1.54, 95% CI 0.64 to 3.70, I2 25.48%, p = 0.33) did not show any significant difference. DR was associated with lower incidence RAO when compared with TR, whereas other procedural-related complications were similar.

Efficacy and Safety of Catheter Ablation vs Antiarrhythmic Drugs as Initial Therapy for Management of Symptomatic Paroxysmal Atrial Fibrillation: A Meta-Analysis.

BACKGROUND: Catheter ablation is an effective treatment for atrial fibrillation (AF), primarily performed in patients who fail antiarrhythmic drugs. Whether early catheter ablation, as first-line therapy, is associated with improved clinical outcomes remains unclear. METHODS: Electronic databases (PubMed, Scopus, Embase) were searched until March 28th, 2021. Randomized controlled trials (RCTs) compared catheter ablation vs antiarrhythmic drug therapy as first-line therapy were included. The primary outcome of interest was the first documented recurrence of any atrial tachyarrhythmia (symptomatic or asymptomatic; AF, atrial flutter, and atrial tachycardia). Secondary outcomes included symptomatic atrial tachyarrhythmia (AF, atrial flutter, and atrial tachycardia) and serious adverse events. Unadjusted risk ratios (RR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance considered if the confidence interval (CI) excludes one and p < 0.05. RESULTS: A total of six RCTs with 1212 patients (Ablation n = 609; Antiarrhythmic n = 603) were included. Follow- up period ranged from 1-2 years. Patients who underwent ablation were less likely to experience any recurrent atrial tachyarrhythmia when compared to patients receiving antiarrhythmic drugs (RR 0.63; 95% CI 0.55-0.73; p < 0.00001). Symptomatic atrial tachyarrhythmia was also lower in the ablation arm (RR 0.53; 95% CI 0.32-0.87; p = 0.01). No statistically significant differences were noted for overall any type of adverse events (RR 0.93; 95% CI 0.68-1.27; p = 0.64) and cardiovascular adverse events (RR 0.90; 95% CI 0.56-1.44; p = 0.65) respectively. CONCLUSIONS: Catheter ablation, as first-line therapy, was associated with a significantly lower rate of tachyarrhythmia recurrence compared to conventional antiarrhythmic drugs, with a similar adverse effect risk profile. These findings support a catheter ablation strategy as first-line therapy among patients with symptomatic paroxysmal atrial fibrillation.

Association of pepper intake with all-cause and specific cause mortality - A systematic review and meta-analysis.

OBJECTIVE: To conduct a comprehensive systematic review and meta-analysis to compare mortality and other clinical outcomes associated with chili pepper (CP) consumption versus no/rare consumption of CP. METHODS: A comprehensive search was performed using Ovid, Cochrane, Medline, EMBASE, and Scopus from inception till January 16, 2020. Observational studies and randomized controlled trials were included, while pediatric/animal studies, letters/case reports, reviews, abstracts, and book chapters were excluded. All-cause mortality was studied as the primary outcome. Cardiovascular mortality, cancer-related deaths and cerebrovascular accidents were studied as secondary outcomes. RESULTS: From 4729 studies, four studies met the inclusion criteria. Random effects pooled analysis showed that all-cause mortality among CP consumers was lower, compared to rare/non-consumers, with a hazard ratio (HR) of 0.87 [95% CI: 0.85-0.90; p<0.0001; I 2=1%]. HR for cardiovascular mortality was 0.83 [95% CI: 0.74-0.95; p = 0.005, I 2=66%] and for cancer-related mortality as 0.92 [95% CI: 0.87-0.97; p = 0.001; I 2=0%]. However, the HR for CVA was 0.78 [95% CI: 0.56-1.09; p = 0.26; I2 =60%]. The mode and amount of CP consumption varied across the studies, and data were insufficient to design an optimal strategy guiding its intake. CONCLUSION: Regular CP consumption was associated with significantly lower all-cause, cardiovascular, and cancer-related mortalities. However, based on current literature, it is difficult to derive a standardized approach to guide the optimal mode and amount of CP consumption. This warrants well-designed prospective studies to further investigate the potential health benefits of CP consumption.

Utilization and outcomes of aortic valve replacements (from the United States readmissions database).

Study objective: Assess the utilization of aortic valve replacements (AVR). Design: Retrospective analysis of the Nationwide Readmissions Database (2016-2018). Setting: Nationwide. Participants: Heart failure patients with concomitant aortic stenosis (CHF + AS cohort) or aortic stenosis with aortic regurgitation (CHF + AS+AR cohort). Interventions: Transcatheter aortic valve implantation (TAVI), surgical aortic valve replacement (SAVR), no-AVR. Main outcome measures: Utilization of treatment interventions. Results: In the CHF + AS cohort, TAVI, SAVR and no-AVR were done in 9.3 %, 10.8 % and 79.9 % of patients respectively. Similarly, majority of CHF + AS+AR patients were managed with no-AVR (53.2 %). Of patients managed with no-AVR in the first six months of each year, only 7.9 % of CHF + AS and 11.8 % of CHF + AS+AR patients underwent AVR in the subsequent six months of the year. No-AVR patients had worse short-term outcomes in comparison to AVR recipients. Conclusion: More studies are needed to understand the timing, indications and utilization of AVR in this population.

Refractory Recurrent Pericarditis After Pericardiectomy in a Young Woman.

Pericardiectomy is the recommended treatment for patients with recurrent pericarditis and refractory symptoms despite optimal anti-inflammatory therapy. We present a case of a 40-year-old woman who underwent total pericardiectomy after multiple episodes of pericarditis that was refractory to optimal guideline-derived medical therapy, including anti-inflammatory and biologic agents, who continued to have relapsing symptoms even after pericardiectomy. (Level of Difficulty: Intermediate.).

Artificial intelligence in the diagnosis and detection of heart failure: the past, present, and future.

Artificial Intelligence (AI) performs human intelligence-dependant tasks using tools such as Machine Learning, and its subtype Deep Learning. AI has incorporated itself in the field of cardiovascular medicine, and increasingly employed to revolutionize diagnosis, treatment, risk prediction, clinical care, and drug discovery. Heart failure has a high prevalence, and mortality rate following hospitalization being 10.4% at 30-days, 22% at 1-year, and 42.3% at 5-years. Early detection of heart failure is of vital importance in shaping the medical, and surgical interventions specific to HF patients. This has been accomplished with the advent of Neural Network (NN) model, the accuracy of which has proven to be 85%. AI can be of tremendous help in analyzing raw image data from cardiac imaging techniques (such as echocardiography, computed tomography, cardiac MRI amongst others) and electrocardiogram recordings through incorporation of an algorithm. The use of decision trees by Rough Sets (RS), and logistic regression (LR) methods utilized to construct decision-making model to diagnose congestive heart failure, and role of AI in early detection of future mortality and destabilization episodes has played a vital role in optimizing cardiovascular disease outcomes. The review highlights the major achievements of AI in recent years that has radically changed nearly all areas of HF prevention, diagnosis, and management.

Impact of Frailty and Mitral Valve Surgery on Outcomes of Severe Mitral Stenosis Due to Mitral Annular Calcification.

We sought to evaluate the outcomes of patients with severe mitral stenosis (MS) resulting from mitral annular calcification and assessed the prognostic impact of co-morbidities and frailty in guiding management. Among 6,915 patients with calcific MS who underwent echocardiography between January 2011 and March 2020, a total of 283 patients with severe calcific MS were retrospectively enrolled. We calculated the Charlson co-morbidity index (CCI). Frailty was scored from 0 to 3 points, with 1 point each assigned for reduced hemoglobin, reduced albumin, and inactivity. The primary end point was all-cause death. The mean age was 72 ± 11 years. The mean mitral valve (MV) area was 1.1 ± 0.4 cm2, and the mean transmitral gradient was 12 ± 4 mm Hg. Although 33% of the patients underwent MV intervention, 67% were conservatively managed. During a median follow-up of 360 days, 35% died. Patients who underwent MV intervention had an improved prognosis compared with those who were treated conservatively, even after propensity score matching. On multivariate Cox regression analysis, higher CCI (hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.04 to 1.38, p = 0.011) and frailty score (HR 1.58, 95% CI 1.12 to 2.23, p = 0.01) were predictors of all-cause mortality, and MV intervention (HR 0.45, 95% CI 0.25 to 0.83, p = 0.011) and angiotensin converting enzyme inhibitor/angiotensin receptor blocker use (HR 0.39, 95% CI 0.20 to 0.79, p = 0.009) were associated with an improved prognosis. In conclusion, patients with severe calcific MS were often frail with multiple co-morbidities and were often managed conservatively. Higher CCI and worse frailty were associated with worse prognosis, regardless of the treatment strategy. MV intervention for select patients was associated with improved prognosis.

Outcomes After Transfemoral Transcatheter Aortic Valve Implantation With a SAPIEN 3 Valve in Patients With Cirrhosis of the Liver (a Tertiary Care Center Experience).

Little is known about the utility of transcatheter aortic valve implantation (TAVI) in patients with cirrhosis of the liver, and their outcomes have not been studied extensively in literature. We performed a retrospective analysis of patients with severe symptomatic aortic stenosis (AS) who underwent transfemoral TAVI with a SAPIEN 3 valve at our institution between April 2015 and December 2018. We identified 32 consecutive patients with evidence of cirrhosis of the liver on imaging (including ultrasound and/or computed tomography) and patients with severe symptomatic AS who underwent transfemoral TAVI with a SAPIEN 3 valve. Among 1,028 patients, 32 had cirrhosis of the liver and 996 constituted the control group without cirrhosis. Mean age in the cirrhosis group was 74.5 years compared with 81.2 years in the control group. Baseline variables were comparable between the groups. Compared with the noncirrhotic group, patients with cirrhosis had a similar 1-year mortality (12% vs 12%, p = 1), a lower 30-day new pacemaker after TAVI rate (6% vs 9%, p = 0.85), a higher 30-day and 1-year readmission rate for heart failure (11% vs 1% and 12% vs 5%, p = 0.12, respectively), and a similar 1-year major adverse cardiac and cerebrovascular event rate (15% vs 14%, p = 0.98). In conclusion, patients with severe AS with concomitant liver cirrhosis who underwent TAVI demonstrated comparable outcomes to their noncirrhotic counterparts.

Cardiac manifestations of the coronavirus disease-19: a review of pathogenesis, clinical manifestations, diagnosis, and treatment.

The coronavirus disease-19 (COVID-19), first appearing in Wuhan, China, and later declared as a pandemic, has caused serious morbidity and mortality worldwide. Severe cases usually present with acute respiratory distress syndrome (ARDS), pneumonia, acute kidney injury (AKI), liver damage, or septic shock. However, with recent advances in severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) research, the virus´s effect on cardiac tissues has become evident. Reportedly, an increased number of COVID-19 patients manifested serious cardiac complications such as heart failure, increased troponin, and N-terminal pro-B-type natriuretic peptide levels (NT-proBNP), cardiomyopathies, and myocarditis. These cardiac complications initially present as chest tightness, chest pain, and heart palpitations. Diagnostic investigations such as telemetry, electrocardiogram (ECG), cardiac biomarkers (troponin, NT-proBNP), and inflammatory markers (D-dimer, fibrinogen, PT, PTT), must be performed according to the patient´s condition. The best available options for treatment are the provision of supportive care, anti-viral therapy, hemodynamic monitoring, IL-6 blockers, statins, thrombolytic, and anti-hypertensive drugs. Cardiovascular disease (CVD) healthcare workers should be well-informed about the evolving research regarding COVID-19 and approach as a multi-disciplinary team to devise effective strategies for challenging situations to reduce cardiac complications.
