ABSTRACT Introduction and objectives: The COVID-19 epidemic and the declaration of the state of alarm have led to a decrease in healthcare activity in interventional cardiology units. The objective ...of this study is to quantify these changes in activity, with special interest in the treatment of patients with ST-segment elevation myocardial infarction (STEMI). Methods: A telematic survey of 81 centers involved in STEMI networks in the 17 autonomous communities of Spain. Information was collected on diagnostic activity, percutaneous coronary intervention (PCI), structural interventions, and PCI in STEMI on changes in the organization of STEMI networks, and on the prevalence of COVID-19 among interventional cardiologists. Data was compared for the week of February 24 through March 1 (before the outbreak) and for the week of March 16 through March 22 (during the outbreak). Results: Response has been obtained from 73 centers (90%). A very significant decrease in the number of diagnostic procedures (─56%), PCI (─48%), structural interventions (─81%) and PCI in STEMI (─40%) has been observed. A slight increase in the use of pharmacological thrombolysis has been reported, although primary angioplasty remains the leading reperfusion strategy. Up to 5% of interventional cardiologists (17) had COVID-19. Conclusions: An important reduction in the activity in interventional cardiology has been observed during the COVID-19 epidemic. Likewise, a great decrease has been detected in the number of patients treated in the STEMI networks, with the risk of increased morbidity and mortality that this represents. Scientific societies and health authorities have to promote that patients presenting STEMI compatible symptoms proceed with no delay to access the health system to receive reperfusion treatment in an appropriate way.
Advanced chronic kidney disease (A-CKD) combined with atrial fibrillation increases the risk of both thrombogenic and bleeding events. Left atrial appendage occlusion (LAAO) may be an alternative to ...oral anticoagulation to prevent thromboembolic events. We aimed to evaluate the outcomes of LAAO in patients with A-CKD.
Comparison at long-term follow-up of patients diagnosed with and without A-CKD (eGFR<30 mL/min/1.73 m
) who underwent LAAO between 2009 and May 2022.
Five hundred seventy-three patients were included. Eighty-one (14%) were diagnosed with A-CKD. There were no differences in sex, age, and cardiovascular risk factors, except for diabetes which was more frequent in patients with A-CKD. The control group had higher rates of stroke, both ischemic and hemorrhagic. There were no differences in the CHA
DS
-VASc score, although A-CKD patients had a higher bleeding risk according to the HASBLED scale. Global procedural success was 99.1%. At follow-up, there were no differences in stroke rate: at 1-year (HR: 1.22, IC-95%: 0.14-10.42, p = 0.861); at 5-years (HR: 0.60, IC-95%: 0.08-4.58, p = 0.594). Although bleeding events were higher in the A-CKD group, no differences were found in major bleeding (defined BARC ≥ 3) at 1-year (HR: 1.34, IC-95%: 0.63-2.88, p = 0.464) or at 5-years follow-up (HR: 1.30, IC-95%: 0.69-2.48, p = 0.434). Mortality rate at 5 years was higher in the A-CKD patients (HR: 1.84, IC-95%: 1.18-2.87, p = 0.012).
LAAO is an effective and safe treatment in A-CKD patients to prevent ischemic events and bleeding. This strategy could be an alternative to oral anticoagulation in this high-risk group of patients.
Abstract
Aims
We aimed to determine whether treatment with sildenafil improves outcomes of patients with persistent pulmonary hypertension (PH) after correction of valvular heart disease (VHD).
...Methods and results
The sildenafil for improving outcomes after valvular correction (SIOVAC) study was a multricentric, randomized, parallel, and placebo-controlled trial that enrolled stable adults with mean pulmonary artery pressure ≥ 30 mmHg who had undergone a successful valve replacement or repair procedure at least 1 year before inclusion. We assigned 200 patients to receive sildenafil (40 mg three times daily, n = 104) or placebo (n = 96) for 6 months. The primary endpoint was the composite clinical score combining death, hospital admission for heart failure (HF), change in functional class, and patient global self-assessment. Only 27 patients receiving sildenafil improved their composite clinical score, as compared with 44 patients receiving placebo; in contrast 33 patients in the sildenafil group worsened their composite score, as compared with 14 in the placebo group odds ratio 0.39; 95% confidence interval (CI) 0.22–0.67; P < 0.001. The Kaplan–Meier estimates for survival without admission due to HF were 0.76 and 0.86 in the sildenafil and placebo groups, respectively (hazard ratio 2.0, 95% CI = 1.0–4.0; log-rank P = 0.044). Changes in 6-min walk test distance, natriuretic peptides, and Doppler-derived systolic pulmonary pressure were similar in both groups.
Conclusion
Treatment with sildenafil in patients with persistent PH after successfully corrected VHD is associated to worse clinical outcomes than placebo. Off-label usage of sildenafil for treating this source of left heart disease PH should be avoided.
The trial is registered with ClinicalTrials.gov, number NCT00862043.
The COVID-19 outbreak has had an unclear impact on the treatment and outcomes of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess changes in STEMI ...management during the COVID-19 outbreak.
Using a multicenter, nationwide, retrospective, observational registry of consecutive patients who were managed in 75 specific STEMI care centers in Spain, we compared patient and procedural characteristics and in-hospital outcomes in 2 different cohorts with 30-day follow-up according to whether the patients had been treated before or after COVID-19.
Suspected STEMI patients treated in STEMI networks decreased by 27.6% and patients with confirmed STEMI fell from 1305 to 1009 (22.7%). There were no differences in reperfusion strategy (> 94% treated with primary percutaneous coronary intervention in both cohorts). Patients treated with primary percutaneous coronary intervention during the COVID-19 outbreak had a longer ischemic time (233 150-375 vs 200 140-332 minutes,
< .001) but showed no differences in the time from first medical contact to reperfusion. In-hospital mortality was higher during COVID-19 (7.5% vs 5.1%; unadjusted OR, 1.50; 95%CI, 1.07-2.11;
< .001); this association remained after adjustment for confounders (risk-adjusted OR, 1.88; 95%CI, 1.12-3.14;
= .017). In the 2020 cohort, there was a 6.3% incidence of confirmed SARS-CoV-2 infection during hospitalization.
The number of STEMI patients treated during the current COVID-19 outbreak fell vs the previous year and there was an increase in the median time from symptom onset to reperfusion and a significant 2-fold increase in the rate of in-hospital mortality. No changes in reperfusion strategy were detected, with primary percutaneous coronary intervention performed for the vast majority of patients. The co-existence of STEMI and SARS-CoV-2 infection was relatively infrequent.
BACKGROUNDSevere tricuspid regurgitation (TR) is frequently associated with significant morbidity and mortality; such patients are often deemed to be at high surgical risk. Heterotopic bicaval ...stenting is an emerging, attractive transcatheter solution for these patients. OBJECTIVESThe aim of this study was to evaluate the 30-day safety and 6-month efficacy outcomes of specifically designed bioprosthetic valves for the superior and inferior vena cava. METHODSTRICUS EURO (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) is a nonblinded, nonrandomized, single-arm, multicenter, prospective trial that enrolled patients from 12 European centers between December 2019 and February 2021. High-risk individuals with severe symptomatic TR despite optimal medical therapy were included. The primary endpoint was quality-of-life (QOL) improvement measured by Kansas City Cardiomyopathy Questionnaire score and New York Heart Association (NYHA) functional class improvement at 6-month follow-up. RESULTSThirty-five patients (mean age 76 ± 6.8 years, 83% women) were treated using the TricValve system. All patients at baseline were in NYHA functional class III or IV. At 30 days, procedural success was 94%, with no procedural deaths or conversions to surgery. A significant increase in QOL at 6 months follow-up was observed (baseline and 6-month Kansas City Cardiomyopathy Questionnaire scores 42.01 ± 22.3 and 59.7 ± 23.6, respectively; P = 0.004), correlating with a significant improvement in NYHA functional class, with 79.4% of patients noted to be in functional class I or II at 6 months (P = 0.0006). The rates of 6-month all-cause mortality and heart failure hospitalization were 8.5% and 20%, respectively. CONCLUSIONSThe dedicated bicaval system for treating severe symptomatic TR was associated with a high procedural success rate and significant improvements in both QOL and functional classification at 6 months follow-up.
ABSTRACT Vascular access is an essential part of all interventional procedures whether coronary or structural. Over the last 15 to 20 years, in coronary interventions, traditional femoral access has ...been mostly replaced by the radial approach. Nonetheless, the femoral approach through both artery and vein is still the main approach for structural heart procedures. Over the last few years, femoral access has evolved from a puncture guided by anatomical references to more accurate ultrasound-guided approaches. The relatively recent introduction of interventions such as transcatheter aortic valve replacement has conditioned the use of large introducers and ultimately the need for specific hemostatic systems, above all, percutaneous closure devices. This manuscript reviews different anatomical concepts, puncture techniques, diagnostic assessments, and closure strategies of the main arterial and venous approaches for the diagnosis and treatment of different structural heart procedures.
Iodinated contrast media (CM) are the leading cause of acute renal failure of toxic origin. Between 21% and 50% of patients that receive them develop contrast-induced nephropathy (CIN). All ...prophylactic measures used so far have failed to provide effective prevention. Since oxidative stress is involved in the damage, a possible preventive strategy could be the administration of antioxidant substances, such as quercetin. This compound has shown renoprotective effects in experimental studies. The aim of this study was to evaluate whether quercetin may be helpful in preventing CIN in patients undergoing coronary catheterization. A clinical phase II study was conducted. Patients were distributed in two groups, namely, CM (patients who only received contrast media) and CM+Q (patients who were pretreated with quercetin orally for 3-5 days). Results showed less incidence of CIN in the CM+Q group, possibly due to glomerular protection, evidenced by a lower increase in serum creatinine and albuminuria; and a lower decrease in the glomerular filtration rate (GFR). Furthermore, in this group, the relative risk of developing CIN observed in patients that received a high dose of contrast media was inferior. In conclusion, this is the first study that demonstrates that quercetin is a promising safe candidate in preventing CIN.
