Background Takotsubo (or stress induced) cardiomyopathy is characterized by transient left ventricular systolic dysfunction. Recent trends in patient volume, characteristics, and outcomes in the ...United States are unknown. Methods Using 2007-2012 National Inpatient Sample data, we identified 22,005 adults (≥18 years) with a primary and 31,942 adults with a secondary discharge diagnosis of takotsubo cardiomyopathy ( International Classification of Diseases, Ninth Revision , code 429.83) who underwent diagnostic coronary angiography. Results During 2007 to 2012, the incidence of takotsubo cardiomyopathy increased over 3-fold: 52/million discharges in 2007 to 178/million in 2012 ( P < .001). We found a temporal increase in the prevalence of cardiac arrest, cardiogenic shock, cardiovascular risk factors (diabetes, hypertension), and psychiatric disorders ( P trend < .0001 for all). In-hospital mortality was 1.1% and remained unchanged over this period ( P = .22). Compared to the primary diagnosis group, mortality in the secondary diagnosis group was higher (1.1% vs 3.2%) and was associated with higher incidence of cardiogenic shock, cardiac arrest, and respiratory failure. Men represent 8% of patients in the primary diagnosis group and 12% in the secondary group. In both groups, men had a higher incidence of shock, cardiac arrest, and respiratory failure. Although their mortality was higher than women in the primary group (3.0% vs 0.9%, adjusted odds ratio 3.85, 1.74-8.51), it was comparable in the secondary group (4.8% vs 3.0%). Conclusions We found a marked increase in the hospitalization for takotsubo cardiomyopathy in the United States in recent years, suggesting higher incidence than prior reports. Although outcomes have remained favorable, there is an increasing burden of cardiovascular and psychiatric disorders in this population with growing cost of care. Risk of mortality is higher in men and in patients with underlying critical illness. The excess mortality in these groups appears to be mediated by greater severity of disease.
Severe symptomatic degenerative mitral regurgitation (DMR) has a poor prognosis in the absence of treatment, and new transcatheter options are emerging.
The CLASP IID (Edwards PASCAL Transcatheter ...Valve Repair System Pivotal Clinical Trial) randomized trial (NCT03706833) is the first to evaluate the safety and effectiveness of the PASCAL system compared with the MitraClip system in patients with significant symptomatic DMR. This report presents the primary safety and effectiveness endpoints for the trial.
Patients with 3+ or 4+ DMR at prohibitive surgical risk were assessed by a central screening committee and randomized 2:1 (PASCAL:MitraClip). Study oversight also included an echocardiography core laboratory and a clinical events committee. The primary safety endpoint was the composite major adverse event rate at 30 days. The primary effectiveness endpoint was the proportion of patients with mitral regurgitation (MR) ≤2+ at 6 months.
A prespecified interim analysis in 180 patients demonstrated noninferiority of the PASCAL system vs the MitraClip system for the primary safety and effectiveness endpoints of major adverse event rate (3.4% vs 4.8%) and MR ≤2+ (96.5% vs 96.8%), respectively. Functional and quality-of-life outcomes significantly improved in both groups (P < 0.05). The proportion of patients with MR ≤1+ was durable in the PASCAL group from discharge to 6 months (PASCAL, 87.2% and 83.7% P = 0.317 vs discharge; MitraClip, 88.5% and 71.2% P = 0.003 vs discharge).
The CLASP IID trial demonstrated safety and effectiveness of the PASCAL system and met noninferiority endpoints, expanding transcatheter treatment options for prohibitive surgical risk patients with significant symptomatic DMR.

Chest radiation therapy (XRT) has been associated with a higher rate of mortality following surgical aortic valve replacement. We performed a single-center retrospective analysis of patients with ...severe AS who underwent TAVI from January 1 2012 to July 31 2020 comparing patients with and without XRT. A total of 915 patients met inclusion criteria, with a total of 50 patients found to have a history of XRT. At a mean follow-up of 2.4 years, unadjusted and propensity score matching analysis demonstrated no differences in mortality, heart failure or bleeding-related hospitalization, overall stroke, and 30-day pacemaker implantation in patients with and without XRT.
Transcatheter aortic valve replacement (TAVR) is well‐established for the treatment of bioprosthetic aortic valve stenosis (AS) in high surgical risk patients. Coronary artery obstruction from ...displacement of the bioprosthetic valve leaflets during valve‐in‐valve (VIV) TAVR is a rare, but potentially fatal, complication. Recently, the bioprosthetic aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) procedure was developed as a method for disrupting bioprosthetic leaflets in patients undergoing VIV TAVR at high risk for coronary obstruction. This case describes a successful VIV TAVR utilizing a simplified concept of the BASILICA technique in a patient where the full procedure could not be completed.
Patients who underwent transcatheter aortic valve implantation (TAVI) with a history of atrial fibrillation (AF) have higher rates of all-cause mortality, inpatient complications, and length of ...hospitalization.1–3 However, intermediate-term outcomes and the impact of stroke risk as calculated by CHA2DS2-VASc scores in the AF population who underwent TAVI have not previously been described. The efficacy of left atrial appendage closure in conjunction with the TAVI procedure awaits the results of data from the WATCH-TAVR (WATCHMAN for Patients With Atrial Fibrillation Undergoing Transcatheter Aortic Valve Replacement) trial. ...pre-TAVI AF is associated with an increased rate of adverse events.
Patients with a history of chronic lung disease requiring supplemental home oxygen have a higher risk for morbidity and mortality related to surgical aortic valve replacement (SAVR) in a setting of ...severe aortic stenosis (AS).1 Furthermore, trials assessing transcatheter aortic valve implantation (TAVI) versus SAVR excluded this subgroup. ...it shows that TAVI demonstrates similar all-cause mortality in patients with supplemental home oxygen use compared with those without. ...despite the overall higher STS risk for valvular intervention in severe AS in patients with home oxygen use than those without, the intermediate-term mortality risk and clinical outcomes following TAVI are comparable in the 2 groups.
Whilst causes of hepatic artery thrombosis (HAT) after liver transplantation (LT) are multifactorial, early HAT (E-HAT) remains pertinent complication impacting on graft and patient survival. ...Currently there is no screening tool that would identify patients with increased risk of developing E-HAT.
We analyzed the native procoagulant state of LT recipients, identified through pretransplant thromboelastographic (TEG) data among other known risk factors, to identify risk factors for E-HAT.
The outcomes of 828 adult patients undergoing LT between 2008 and 2013 were analyzed. Overall, 79 (9.5%) patients experienced HAT, E-HAT was diagnosed in 23, and in the remainder this was "late" HAT. The maximum amplitude (MA) on preoperative TEG was significantly higher in patients diagnosed with E-HAT compared with those who did not (71.2 mm vs 57.9 mm; P < 0.0001). Receiver operating characteristic analysis with the cutoff value for MA of 65 mm or greater returned area under the curve of 0.750 (P < 0.001) predicting E-HAT with a sensitivity of 70%. A total of 7% of patients with an MA of 65 mm or greater went on to develop E-HAT (hazard ratio, 5.28; 95% confidence interval, 2.10-12.29; P < 0.001), whereas only 1.2% patients with an MA less than 65 mm experienced E-HAT.
Preoperative TEG may reliably identify group of recipients at greater risk of developing E-HAT, and intense surveillance and anticoagulation prophylaxis may avoid this serious complication after LT.
