RCT: Interruption of Oral Anticoagulation during TAVI Reduces Bleeding Without Increasing Thromboembolic Events
7 Sep, 2024 | 12:43h | UTCStudy Design and Population: This international, open-label, randomized noninferiority trial examined 858 patients undergoing transcatheter aortic-valve implantation (TAVI) who had an indication for oral anticoagulation due to concomitant diseases. Patients were randomized 1:1 to either continue or interrupt their oral anticoagulation during the procedure, with the primary outcome being a composite of cardiovascular death, stroke, myocardial infarction, major vascular complications, or major bleeding within 30 days.
Main Findings: Primary outcome events occurred in 16.5% of the continuation group and 14.8% of the interruption group, showing a non-significant risk difference of 1.7 percentage points (95% CI, -3.1 to 6.6). Thromboembolic events were similar between groups (8.8% in continuation vs. 8.2% in interruption). However, bleeding events were significantly higher in the continuation group (31.1% vs. 21.3%; risk difference, 9.8 percentage points; 95% CI, 3.9 to 15.6).
Implications for Practice: Interrupting oral anticoagulation during TAVI significantly reduces bleeding without increasing thromboembolic risks, suggesting it may be a safer strategy for patients undergoing TAVI. These findings could influence clinical decision-making regarding anticoagulation management in this population.

News Release: SCOFF Trial Confirms Fasting Not Necessary Before Cardiac Catheterisation Procedures
7 Sep, 2024 | 10:10h | UTC1 September 2024 – London, United Kingdom – New findings from the SCOFF trial, presented at ESC Congress 2024, suggest that fasting prior to minimally invasive cardiac catheterisation procedures under conscious sedation does not increase the risk of complications. The trial supports reconsidering current guidelines on pre-procedural fasting.
Key Points for Physicians:
– No increased complications: The SCOFF trial found no significant difference in adverse outcomes, such as aspiration pneumonia or hypoglycemia, between patients who fasted and those who ate normally before cardiac catheterisation.
– Improved patient satisfaction: Patients who did not fast reported higher satisfaction, with fewer complaints of discomfort and hunger.
– Potential guideline change: These findings, in line with previous studies like CHOW-NOW and TONIC, challenge the necessity of fasting before such procedures.
The trial’s lead investigator, Dr. David Ferreira (John Hunter Hospital, Australia), emphasized that avoiding fasting may improve patient experience without increasing risks, making it time to reconsider fasting guidelines for these procedures.
Study Overview:
– Trial design: Prospective, randomized, open-label, with blinded endpoint assessment.
– Participants: 716 patients undergoing coronary angiography, coronary intervention, or cardiac implantable electronic device procedures.
– Primary endpoint: Composite of hypotension, aspiration pneumonia, hyperglycemia, and hypoglycemia, showing a lower event rate in the non-fasting group (12.0%) compared to the fasting group (19.1%).
These results are likely to influence future clinical practice, providing greater flexibility for both patients and healthcare systems.
RCT: Hypothermic Oxygenated Perfusion Trends Toward Lower Primary Graft Dysfunction in Heart Transplantation – The Lancet
17 Aug, 2024 | 19:38h | UTCStudy Design and Population: This randomized, controlled, open-label, multicenter clinical trial evaluated the safety and efficacy of hypothermic oxygenated machine perfusion (HOPE) compared to static cold storage (SCS) in preserving donor hearts for transplantation. Conducted across 15 transplant centers in eight European countries, the study enrolled 229 adult heart transplant candidates between November 2020 and May 2023. The trial included 204 patients who received a transplant and met the study’s inclusion and exclusion criteria.
Main Findings: The primary composite endpoint, including cardiac-related death, graft dysfunction, and rejection within 30 days post-transplant, occurred in 19% of patients in the HOPE group compared to 30% in the SCS group, reflecting a 44% risk reduction (HR 0.56, 95% CI 0.32–0.99, p=0.059). Notably, primary graft dysfunction was significantly lower in the HOPE group (11% vs. 28%, RR 0.39, 95% CI 0.20–0.73). The incidence of major adverse cardiac transplant events was also reduced with HOPE (18% vs. 32%, RR 0.56, 95% CI 0.34–0.92).
Implications for Practice: HOPE showed a potential clinical benefit by reducing the incidence of primary graft dysfunction and major adverse cardiac events after heart transplantation. Although the primary endpoint was not statistically significant, the observed risk reductions suggest that HOPE could improve outcomes in heart transplantation. Further research is needed to confirm these findings and optimize donor heart preservation strategies.
RCT: Routine Protamine Administration Enhances Hemostasis and Reduces Vascular Complications in TAVI – JAMA Cardiol
17 Aug, 2024 | 19:09h | UTCStudy Design and Population: The ACE-PROTAVI trial was a double-blind, placebo-controlled randomized clinical trial conducted at three Australian hospitals. It involved 410 patients (median age 81 years) undergoing transfemoral transcatheter aortic valve implantation (TAVI). The trial evaluated the efficacy and safety of routine protamine administration versus placebo.
Main Findings: Patients receiving protamine showed a higher rate of successful hemostasis (97.9% vs. 91.6%) and a significantly shorter time to hemostasis (median 181 vs. 279 seconds). Protamine administration also led to a reduced risk of composite vascular complications (5.2% vs. 12.8%), primarily due to fewer minor vascular events. No adverse events were associated with protamine.
Implications for Practice: Routine protamine administration after TAVI improves hemostasis, reduces minor vascular complications, and shortens procedural and postprocedural recovery times, suggesting it should be considered in standard TAVI protocols.
RCT: Intravenous Amino Acids Reduce AKI Incidence in Cardiac Surgery Patients – N Engl J Med
3 Aug, 2024 | 19:12h | UTCStudy Design and Population: In this multinational, double-blind, randomized clinical trial, 3511 adult patients scheduled for cardiac surgery with cardiopulmonary bypass were recruited from 22 centers across three countries. Patients were randomly assigned to receive an intravenous infusion of either a balanced mixture of amino acids (2 g/kg/day) or a placebo (Ringer’s solution) for up to three days.
Main Findings: The primary outcome, occurrence of acute kidney injury (AKI), was significantly lower in the amino acid group (26.9%) compared to the placebo group (31.7%) with a relative risk of 0.85 (95% CI, 0.77 to 0.94; P=0.002). The incidence of severe AKI (stage 3) was also reduced in the amino acid group (1.6% vs. 3.0%; relative risk, 0.56; 95% CI, 0.35 to 0.87). There were no substantial differences between the groups regarding secondary outcomes such as the use and duration of kidney-replacement therapy or all-cause 30-day mortality.
Implications for Practice: The infusion of amino acids in adult patients undergoing cardiac surgery appears to reduce the incidence of AKI, indicating a potential protective renal effect. However, this intervention did not significantly impact other secondary outcomes, including mortality and the use of kidney-replacement therapy. These findings suggest that amino acids could be considered as a strategy to mitigate AKI risk in this patient population, although further research is needed to explore long-term benefits and other clinical outcomes.
RCT: Serratus anterior plane block reduces pain and opioid use in rib fracture patients – JAMA Surgery
2 May, 2024 | 23:20h | UTCStudy Design and Population:
This study was a multicenter, open-label, pragmatic randomized clinical trial conducted across eight emergency departments in New South Wales, Australia. The trial included 210 patients aged 16 years or older who had clinically suspected or radiologically confirmed rib fractures. Patients intubated, transferred for urgent surgical intervention, or with major concomitant nonthoracic injuries were excluded.
Main Findings:
In the trial, patients were randomized to receive either a serratus anterior plane block (SAPB) along with standard rib fracture management or standard care alone. The primary outcome was a composite pain score measured 4 hours post-enrollment. The SAPB group showed a significant increase in patients achieving the desired pain score reduction (41% in SAPB group vs. 19.6% in control; RR 0.73, 95% CI 0.60-0.89, P = 0.001). Additionally, SAPB recipients had significantly lower opioid consumption at 24 hours compared to the control group.
Implications for Practice:
The trial’s results support the addition of a serratus anterior plane block (SAPB) to standard rib fracture management for providing effective early pain relief and reducing opioid use. However, it’s important to note that this study did not include a sham group, and patients were aware of whether they received the intervention. This lack of blinding could influence patient-reported outcomes due to placebo effects. Despite this limitation, the reduction in pain and opioid consumption suggests that SAPB is a beneficial component of care for patients with rib fractures.
