Pericardial tamponade after laparoscopic repair of a giant diaphragmatic hernia.

Laparoscopic intraperitoneal onlay mesh repair is favoured for diaphragmatic hernias due to better outcomes. However, fixation devices pose risks, including cardiac tamponade. A man underwent laparoscopic repair for a large diaphragmatic hernia. One week later, he presented with chest discomfort which was initially attributed to postoperative pain. Subsequently, patient represented with worsening of chest pain and tachycardia. CT requested to rule out pulmonary embolism revealed a large pericardial effusion. Urgent drainage via apical approach resolved tamponade. The case highlights the challenges in managing pericardial effusions post-laparoscopy in the presence of diaphragmatic mesh and stresses multidisciplinary collaboration. Literature review highlights risks associated with fixation devices. Suggestions include limiting their use near vital structures. Key learning point of this case report is to raise awareness of cardiac tamponade following diaphragmatic hernia repair. Limited evidence necessitates cautious use of fixation devices, emphasising patient safety.

Health-related quality of life following TAVI or cardiac surgery in patients at intermediate and low risk: a systematic review and meta-analysis.

Recent randomised trials have shown that clinical outcomes with transcatheter aortic valve implantation (TAVI) are non-inferior to surgical aortic valve replacement (SAVR) in patients with symptomatic aortic stenosis at intermediate to low risk. Health-related quality of life (HrQoL) outcomes in these patient groups remain uncertain. A systematic search of the literature was conducted that included nine trials and 11,295 patients. Kansas City Cardiomyopathy Questionnaire (KCCQ), a heart-failure-specific measure and EuroQol-5D (EQ-5D) (a generic health status tool) changes were the primary outcomes. New York Heart Association (NYHA) classification was the secondary outcome. Improvement in KCCQ scores was greater with TAVI (mean difference (MD)=13.56, 95% confidence interval (CI) 11.67-15.46, p<0.001) at 1 month, as was the improvement in EQ-5D (MD=0.07, 95% CI 0.05-0.08, p<0.001). There was no difference in KCCQ (MD=1.05, 95% CI -0.11 to 2.21, p=0.08) or EQ-5D (MD=-0.01, 95% CI -0.03 to 0.01), p=0.37) at 12 months. NYHA functional class 3/4 was lower in patients undergoing TAVI at 1 month (MD=0.51, 95% CI 0.34-0.78, p=0.002), but there was no difference at 12 months (MD=1.10; 95% CI 0.87-1.38, p=0.43). Overall, TAVI offers early benefit in HRQoL outcomes compared with SAVR, but they are equivalent at 12 months.

Risk Factors Associated With Post-COVID-19 Condition: A Systematic Review and Meta-analysis.

Importance: Post-COVID-19 condition (PCC) is a complex heterogeneous disorder that has affected the lives of millions of people globally. Identification of potential risk factors to better understand who is at risk of developing PCC is important because it would allow for early and appropriate clinical support. Objective: To evaluate the demographic characteristics and comorbidities that have been found to be associated with an increased risk of developing PCC. Data sources: Medline and Embase databases were systematically searched from inception to December 5, 2022. Study Selection: The meta-analysis included all published studies that investigated the risk factors and/or predictors of PCC in adult (≥18 years) patients. Data Extraction and Synthesis: Odds ratios (ORs) for each risk factor were pooled from the selected studies. For each potential risk factor, the random-effects model was used to compare the risk of developing PCC between individuals with and without the risk factor. Data analyses were performed from December 5, 2022, to February 10, 2023. Main Outcomes and Measures: The risk factors for PCC included patient age; sex; body mass index, calculated as weight in kilograms divided by height in meters squared; smoking status; comorbidities, including anxiety and/or depression, asthma, chronic kidney disease, chronic obstructive pulmonary disease, diabetes, immunosuppression, and ischemic heart disease; previous hospitalization or ICU (intensive care unit) admission with COVID-19; and previous vaccination against COVID-19. Results: The initial search yielded 5334 records of which 255 articles underwent full-text evaluation, which identified 41 articles and a total of 860 783 patients that were included. The findings of the meta-analysis showed that female sex (OR, 1.56; 95% CI, 1.41-1.73), age (OR, 1.21; 95% CI, 1.11-1.33), high BMI (OR, 1.15; 95% CI, 1.08-1.23), and smoking (OR, 1.10; 95% CI, 1.07-1.13) were associated with an increased risk of developing PCC. In addition, the presence of comorbidities and previous hospitalization or ICU admission were found to be associated with high risk of PCC (OR, 2.48; 95% CI, 1.97-3.13 and OR, 2.37; 95% CI, 2.18-2.56, respectively). Patients who had been vaccinated against COVID-19 with 2 doses had a significantly lower risk of developing PCC compared with patients who were not vaccinated (OR, 0.57; 95% CI, 0.43-0.76). Conclusions and Relevance: This systematic review and meta-analysis demonstrated that certain demographic characteristics (eg, age and sex), comorbidities, and severe COVID-19 were associated with an increased risk of PCC, whereas vaccination had a protective role against developing PCC sequelae. These findings may enable a better understanding of who may develop PCC and provide additional evidence for the benefits of vaccination. Trial Registration: PROSPERO Identifier: CRD42022381002.

Mechanical extraction of implantable cardioverter-defibrillator leads with a dwell time of more than 10 years: insights from a single high-volume centre.

AIMS: To analyze and compare the effectiveness and safety of transvenous lead extraction (TLE) of implantable cardioverter-defibrillator (ICD) leads with a dwell time of >10 years (Group A) vs. younger leads (Group B) using mechanical extraction systems. METHODS AND RESULTS: Between October 2011 and July 2022, we performed TLE in 318 patients. Forty-six (14.4%) extracted ICD leads in 46 (14.5%) patients that had been implanted for >10 years. The median dwell time of all extracted ICD leads was 5.9 years. Cardiovascular implantable electronic device-related infection was an indication for TLE in 31.8% of patients. Complete ICD leads removal and complete procedural success in both groups were similar (95.7% in Group A vs. 99.6% in Group B, P = 0.056% and 95.6% in Group A vs. 99.6% in Group B, P = 0.056, respectively). We did not find a significant difference between major and minor complication rates in both groups (6.5% in Group A vs. 1.5% in Group B and 2.2% in Group A vs. 1.8% in Group B, P = 0.082, respectively). One death associated with the TLE procedure was recorded in Group B. CONCLUSION: The TLE procedures involving the extraction of old ICD leads were effective and safe. The outcomes of ICD lead removal with a dwell time of >10 years did not differ significantly compared with younger ICD leads. However, extraction of older ICD leads required more frequent necessity for utilizing multiple extraction tools, more experience and versatility of the operator, and increased surgery costs.

Effect of sex and surgical incision on survival after isolated primary mitral valve operations.

OBJECTIVES: Multiple studies have suggested that women have worse outcomes than men following mitral valve (MV) surgery-most of those studies reported on conventional sternotomy (CS) MV surgery. Therefore, we aimed to explore whether or not the minimally invasive mitral valve surgery (MIMVS) approach might mitigate a worse survival in women following MV surgery. METHODS: We identified patients with isolated primary MV operations with or without tricuspid valve repair performed between 2007 and 2019. Patients were propensity score-matched across the MIMVS and CS surgical approaches. Sex was excluded from the matching process to discern whether female patients had a different likelihood of receiving minimally invasive surgery than males. A Cox proportional hazards model was fitted in the matched cohort and adjusted for the imbalance in baseline characteristics using the propensity score. RESULTS: Of 956 patients (417 MIMVS, 539 CS; 424 females), the matched set comprised 342 pairs (684 patients; 296 females) of patients who were well balanced across MIMVS and CS groups with regard to preoperative clinical characteristics. We observed a 47/53% female/male ratio in the CS group and a 39/61% in the MIMVS group, P = 0.054. In both matched groups, women were older than males. A Cox model adjusted for propensity scores showed no survival difference with sex, surgical type or interaction. CONCLUSIONS: Women present to the surgical team at an older age. They appear less likely to be considered for a MIMVS approach than men. Neither sex nor surgical approach was associated with worse survival in a matched sample.

One-year outcomes of percutaneous coronary intervention in native coronary arteries versus saphenous vein grafts in patients with prior coronary artery bypass graft surgery.

BACKGROUND: Patients with prior coronary artery bypass graft (CABG) surgery often require percutaneous coronary intervention (PCI). Data are still limited in regards to the outcomes of native saphenous vein graft (SVG) PCI after CABG. METHODS: We performed a retrospective study in a tertiary reference cardiac center of consecutive patients who underwent PCI after CABG. The data were collected for patients who underwent either native or graft PCI from January 2008 to December 2018. Arterial graft PCIs were excluded. Multivariable Cox regression analysis with propensity matching was performed, and major adverse cardiac events (MACE) outcomes including death or myocardial infarction (MI) or revascularization were assessed at 1-year after each index procedure. RESULTS: A total of 435 PCI were performed in 401 patients (209 had native PCI and 192 had graft PCI). Target lesions were classified as following: 235 (54%) native coronary arteries and 200 (46%) SVG. Propensity matching resulted in 167 matched pairs. In multivariable Cox regression graft PCI relative to native PCI was an independent risk factor for MACE (hazard ratio [HR] 1.725, 95% confidence interval [CI] 1.049-2.837) which was primarily driven by increased incidence in revascularization (HR 2.218, 95% CI 1.193-4.122) and MI (HR 2.248, 95% CI 1.220-4.142) and with no significant difference in mortality (HR 1.118, 95% CI 0.435-2.870). CONCLUSIONS: Compared with native coronary PCI, bypass graft PCI was significantly associated with higher incidence of MACE at 1-year and this was mainly driven by MI and revascularization.

Association between pre-operative right ventricular impairment on transthoracic echocardiography and outcomes after conventional and minimally invasive mitral valve surgery.

BACKGROUND: Right ventricular (RV) impairment may have prognostic value in patients undergoing mitral valve surgery. It is unclear whether RV dysfunction predicts long-term mortality, especially in the era of minimally invasive mitral surgery. METHODS: We performed a retrospective analysis of consecutive patients referred for conventional (via sternotomy) and minimally invasive mitral valve surgery (MIMVS) between 01 January 2013 and 29 August 2018 in a tertiary cardiac centre. We truncated follow-up times at 25 March 2020. RV impairment was defined by reduced RV longitudinal function (TAPSE <17 mm) and/or dilated basal RV diameter (RVD1 > 42 mm). Primary outcome was all-cause mortality. RESULTS: The study cohort included 359 patients followed up for a median period of 4.2 (1.8) years. MIMVS approach was performed in 127 (35.4%) and conventional approach in 232 (64.6%) patients of whom 36 (28%) and 45 (19%), respectively, had RV impairment. EuroSCORE II was significantly higher in patients with RV impairment compared with patients with preserved RV function, irrespective of the surgical approach. Consequently, in both groups, patients with RV impairment had significantly higher mortality compared to patients with preserved RV function. RV impairment adjusted for EuroSCORE II predicted mortality in the whole cohort (HR 2.139, 95% CI 1.249-3.663) and in conventional approach (HR 2.361, 95% CI 1.249-4.465) in contrast to MIMVS (HR 1.570, 95% CI 0.493-4.997). CONCLUSION: In this real world cohort, patients with RV impairment and/or dilation had reduced long-term survival following both conventional surgery and MIMVS. Patients should be referred to surgery prior to worsening of RV function.

Meta-Analysis Comparing Percutaneous to Surgical Access in Trans-Femoral Transcatheter Aortic Valve Implantation.

To compare the outcomes in trans-femoral transcatheter aortic valve implantation (TF-TAVI) performed with percutaneous approach (PC) versus surgical cut-down (SC). In 13 trials including 5,859 patients (PC = 3447, SC = 2412), the outcomes based on Valve Academic Research Consortium criteria were compared between PC and SC in TF-TAVI. Compared with SC, PC was associated with similar major vascular complications (VCs) (8.7% vs 8.5%; odds ratio [OR] = 0.93, 95% confidence interval [CI] = 0.76 to 1.15, p = 0.53), major bleeding (OR = 1.09, 95% CI = 0.66 to 1.8, p = 0.73), perioperative mortality (5.7% vs 5.2%; OR = 1.13, 95% CI = 0.85 to 1.49, p = 0.4), urgent surgical repair (OR = 1.27, 95% CI = 0.81 to 2.02, p = 0.3), stroke (3.3% vs 3.9%; OR = 0.85, 95% CI = 0.53 to 1.36, p = 0.5), myocardial infarction (1.3% vs 1.1%; OR = 1.06, 95% CI = 0.53 to 2.12, p = 0.86), and renal failure (5.2% vs 5.9%; OR = 0.68, 95% CI = 0.38 to 1.22, p = 0.2), but shorter hospital stay (9.1 ± 8.5 vs 9.6 ± 9.5 days; mean difference = -1.07 day, 95% CI = -2.0 to -0.15, p = 0.02) and less blood transfusion (18.5% vs 25.7%; OR = 0.61, 95% CI = 0.43-0.86, p = 0.005). Minor VCs occurred more frequently in PC compared to SC (11.9% vs 6.9%; OR = 1.67, 95% CI = 1.04-2.67, p = 0.03). In conclusion, in TF-TAVI, PC is a safe and feasible alternative to SC, and adopting either approach depends on operator experience after ensuring that vascular access could be safely achieved with that specific technique.

Effectiveness and safety of transvenous extraction of single- versus dual-coil implantable cardioverter-defibrillator leads at single-center experience.

The available literature lacks data concerning direct comparison of the effectiveness and safety of single- versus dual-coil implantable cardioverter-defibrillator (ICD) leads transvenous extraction. Certainly, additional shocking coil in superior vena cava adds to the amount of metal in the vascular system. Adhesions developing around the superior vena cava coil add to the difficulty of extraction of ICD lead if lead removal is required. The aim of the study was to assess the effectiveness and safety of single- and dual-coil ICD leads transvenous extraction using mechanical systems. We performed transvenous lead extraction (TLE) of 197 ICD leads in 196 patients. There were 46 (23.3%) dual-coil leads removed from 46 (23.5%) patients. Cardiovascular implantable electronic device-related infection was an indication for TLE in 25.0% of patients. The following extracting techniques were used: manual direct traction, mechanical telescopic sheaths, controlled-rotation mechanical sheaths, and femoral approach. Complete ICD lead removal and complete procedural success in both groups were similar (99.3% in single-coil vs 97.8% in dual-coil, P = .41 and 99.3% in single-coil vs 97.8% in dual-coil, P = 0.41, respectively). We did not find significant difference between major and minor complication rates in both groups (2.0% in single-coil vs 4.3% in dual-coil, and 0.7% in single-coil vs 0.0% in dual-coil, P = .58, respectively). There was 1 death associated with the TLE procedure of single-coil lead.This study shows that extraction of dual-coil leads seems to be comparably safe and effective to extraction of single-coil leads. On the other hand, it requires longer fluoroscopy time and frequent utilization of advanced tools.

Differences in knowledge among patients with atrial fibrillation receiving non-vitamin K antagonist oral anticoagulants and vitamin K antagonists.

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used for stroke prevention in patients with atrial fibrillation (AF) worldwide. Few articles have compared current understanding of AF patients about the disease and anticoagulant therapy in relation to the medications used. AIM: We sought to compare the knowledge of AF and anticoagulation between AF patients treated with NOACs and those on vitamin K antagonists (VKAs). METHODS: We used the Jessa AF Knowledge Questionnaire (JAKQ), developed and validated in Belgium. Patients were re-cruited at a tertiary centre in Kraków, Poland. RESULTS: A total of 479 AF patients completed the JAKQ. Patients on NOACs (n = 276, 57.6%) compared with those on VKAs (n = 175, 36.5%) did not differ regarding demographic and clinical variables. The mean score of the JAKQ was very similar in the NOAC and VKA group (60.7 ± 17.0% vs. 61.6 ± 17.1%; p = 0.4, respectively). The differences in the proportion of correct responses referred to three questions. Consequences of AF, such as blood clots and cerebral infarction, were more obvious for patients on NOACs compared with those on VKAs (81.5% vs. 70.9%; p = 0.01). The patients on NOACs (78.7% vs. 67.6%; p = 0.009) more frequently considered consulting a physician for advice concerning anticoagulant treatment before surgery, while fewer patients on NOACs were aware of the need to take their medication even if they did not feel AF (76.1% vs. 89.7%; p = 0.0004). Only 25.9% of the VKA patients and 49.3% of the NOAC users knew what to do if they missed a dose of the anticoagulant. CONCLUSIONS: The knowledge of arrhythmia and anticoagulation is better regarding the safety issues among subjects on NOACs compared with those on VKAs. Irrespective of the type of oral anticoagulation therapy, education of AF patients should be improved.

Sex differences in venous stenosis and occlusion in patients with endocardial leads.

Venous stenosis and occlusion (VSO) in the presence of endocardial leads constitute one of the complications of permanent cardiac pacing. At present there are no scientific reports on the influence of sex on the incidence of VSO. AIM: The aim of the study was to examine the influence of sex on the incidence of VSO in patients with earlier implanted endocardial leads in a single-center retrospective analysis. MATERIALS AND METHODS: The material consists of 284 records of consecutive patients admitted to hospital to undergo electrotherapy procedures. In all patients a contrast venography for ipsilateral venous confluence was performed before the procedure. Patients were divided into two groups according to sex criterion. Groups were compared concerning following parameters: demographic characteristics, cardiac implantable electronic device (CIED) characteristics, comorbidities, CHA2DS2-VASc score, selected risk factors for VSO. RESULTS: Group I consist of 101 females, whereas group II consist of 183 males. Both groups did not differ significantly for age, number of implanted endocardial leads and lead dwell time. In the cohort males were with significantly greater burden of morbidity, reflected by the mean result of CHA2DS2-VASc (P=0.0098). In males there was significantly more often chronic heart failure (P<0.0001), chronic obstructive pulmonary disease (P=0.0450) and tobacco use (P=0.0159). Males had more ICD implanted than females (P=0.0270). In the examine cohort 88 patients (31%) had VSO. There was no statistically significant difference in terms of presence of VSO between females and males (P=0.4685). The detailed analysis of the patients with VSO divided according to sex revealed higher morbidity in males. CONCLUSIONS: The equality of VSO incidence in groups of males and females along with the predominance of factors protecting against VSO in group of males support the assumption that female gender is a protective factor against the development of VSO, equally as known protective factors in males.
