BACKGROUND: Solitary hepatocellular carcinoma (HCC) with a diameter of 3-5 cm represents a challenging clinical entity, especially for non-surgical candidates due to comorbidities. CASE: A 74-year-old man with previous history of renal cell carcinoma presented with a new incidental solitary 5 cm liver lesion on MRI. Due to his age and a high risk for post-surgical complications, after multidisciplinary tumor board review the treatment plan consisted of percutaneous thermal segmentectomy using balloon-occluded microwave ablation (b-MWA) followed by balloon-occluded transarterial chemoembolization (b-TACE) with complete tumor necrosis, as evident in subsequent follow-up imaging. This case demonstrates that b-MWA plus b-TACE could be a safe and effective combined therapy for unresectable large HCC lesions, even for those exceeding 3 cm in size. CONCLUSION: Although the presented case is anecdotal and naturally without comparisons or control, it highlights the potential value of percutaneous thermal segmentectomy with a single session combined b-MWA followed by b-TACE for the treatment of large unresectable solitary HCC lesions.

OBJECTIVES: To analyze the prevalence and severity of fetal aortic regurgitation (AR) after undergoing successful fetal aortic valvuloplasty (FAV) and to evaluate its effects on fetal circulation and left ventricular (LV) growth. METHODS: This was a retrospective review of all fetuses with critical aortic stenosis who underwent successful FAV at our center between 2010 and 2024 for whom postnatal echocardiograms were available in digital format. Fetal and postnatal echocardiographic examinations were analyzed for ventricular and valvular dimensions and characteristics, and Z-scores were calculated for middle cerebral artery (MCA) pulsatility index (PI), umbilical artery (UA) PI and cerebroplacental ratio. AR severity was classified into no/mild AR or significant (moderate/severe) AR. The balloon-to-aortic valve ratio (BVR) was calculated as the ratio between the maximum actual balloon diameter and the aortic valve (AV) annulus diameter. The primary endpoints of this study were the prevalence, severity and risk factors for fetal AR following successful FAV. RESULTS: Ninety-nine fetuses who underwent successful FAV were included. Immediate post-FAV echocardiograms showed that 87% of fetuses developed some degree of AR, including 45% of all fetuses with significant AR. BVR was significantly higher in fetuses with significant AR compared to those with no/mild AR (mean, 1.09 (95% CI, 1.06-1.12) vs 1.02 (95% CI, 0.99-1.04); P < 0.001). In a subgroup of 66/99 fetuses with available postnatal echocardiograms, the prevalence of AR decreased significantly from 86% before birth to 58% after birth (P < 0.001), with the proportion of fetuses with significant AR reducing from 47% before birth to 17% after birth (P < 0.001). In the overall cohort of fetuses, AV maximum velocity (Vmax) increased significantly from post-FAV to after birth (mean, 1.93 (95% CI, 1.75-2.11) m/s vs 3.21 (95% CI, 2.89-3.55) m/s; P < 0.001), regardless of AR severity, but Vmax after birth was lower in the significant-AR group compared with the no/mild-AR group (mean, 2.85 m/s vs 3.55 m/s; P = 0.020). Fetuses with significant AR exhibited higher relative LV length increases from immediately post-FAV to after birth than did those with no/mild AR (25% (95% CI, 16-33%) vs 14% (95% CI, 6-21%); P = 0.044), although there was no significant difference in mean LV length Z-score after birth between the two groups. FAV led to significant short-term increases in MCA-PI and UA-PI Z-scores, with greater increases observed in fetuses with significant AR. CONCLUSIONS: FAV is associated with a high prevalence of fetal AR, which lessens in severity over the course of gestation. Significant fetal AR had the largest association with greater BVR and had significant impact on fetal hemodynamics. © 2025 The Author(s).

BACKGROUND: PICC is routinely inserted with assistance of ultrasonography and/or ECG navigation (RI- routine insertion). Only in a minority of patients the insertion of a PICC is difficult and fluoroscopic visualization with introduction of special guidewire is necessary for the success of the procedure (DI-difficult insertion). The aim of the study was to evaluate whether DI can be predicted and associated with a risk of complications during follow-up. METHODS: The study included patients who had a PICC insertion in 2022. The number of patients with RI and DI was recorded and the significance of selected parameters during insertion and the frequency of complications during 1 month follow-up was compared. RESULTS: About 1404 patients had successful PICC insertion in 2022, RI in 1360 (96.8%) and DI in 44 patients (3.2%). There was no significant effect of age, gender, selected vein, its size, insertion site, and tunneling on the course of PICC insertion. However the number of punctures for needle insertion was higher in DI. The complication rate during 1 month follow-up in DI was 9 (20.4%) versus 101 patients (7.4%) in RI (p = 0.002). CONCLUSION: PICC insertion was successful in both RI and DI patients. Of the analyzed parameters, the number of needle punctures was associated with DI, and complications during the 1-month follow-up were more frequently noted in the DI group.

BACKGROUND: Management of recurrent mitral regurgitation (MR) or relevant iatrogenic mitral valve (MV) stenosis after mitral transcatheter edge-to-edge repair (M-TEER) emerges as an increasingly relevant clinical issue. Surgery after M-TEER is associated with higher morbidity and mortality. Electrosurgical leaflet laceration and stabilization of the implant (ELASTA-Clip) followed by transcatheter mitral valve replacement (TMVR) is an innovative, less-invasive treatment option for patients with TEER failure. OBJECTIVES: The authors sought to evaluate the early results of ELASTA-Clip followed by transapical TMVR in patients with symptomatic failed M-TEER (defined as persistent or recurrent MR, or iatrogenic MV stenosis). METHODS: Data from symptomatic patients with failed M-TEER who underwent ELASTA-Clip followed by compassionate use or commercial transapical TMVR using the Abbott Tendyne system were retrospectively collected from 8 tertiary care centers in 4 countries. Safety and efficacy of the procedure were assessed up to 1 year according to Mitral Valve Academic Research Consortium (MVARC) criteria. RESULTS: A total of 22 patients (mean age 77.8 ± 9.2 years, 40.9% [9/22] female) at high surgical risk (EuroSCORE II 8.0 ± 0.4, STS score 7.2% ± 1.1%) with symptomatic residual MR ≥3+ (n = 21) or iatrogenic MV stenosis (n = 1) after failed M-TEER were followed for a median period of 8.5 [Q1-Q3: 2.6-11.6] months. The ELASTA-Clip procedure (90.9% [20/22] transseptal, 9.1% [2/22] transapical) followed by TMVR were successful in all patients (22/22). Technical success according to MVARC was achieved in 21 patients (21/22, 95.4%) without left ventricular outflow tract obstruction or conversion to sternotomy. At 30 days, 3 patients had paravalvular leak progression, ischemic stroke occurred in 3 patients (3/20, 15.0%). Baseline MR (≥3+ in 95.5% [21/22]) was reduced to grade 1+ or less in all patients with durable results in 89.5% (17/19) (P < 0.001). NYHA functional class significantly improved to ≤II in 81.3% (13/16) at discharge (P < 0.001) and 72.2% (13/18) at last follow-up (P < 0.001). At 30 days, all patients (20/20) were alive. Three patients (3/20, 15.0%) were rehospitalized for heart failure (uncontrolled atrial fibrillation in 2 cases) and 1 of them (1/22, 4.5%) underwent a reintervention (valve retensioning). CONCLUSIONS: Transapical TMVR after ELASTA-Clip is a feasible and less invasive option for the management of failed M-TEER that can be performed with acceptable results in a carefully selected patient population. Particular attention is required to avoid paravalvular leakage and measures to minimize the risk of periprocedural cerebrovascular events need to be implemented in future larger-scale prospective studies with longer-term follow-up.

BACKGROUND: Advancing the retrograde microcatheter (MC) into the antegrade guide catheter during retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can be challenging or impossible, preventing guidewire externalization. OBJECTIVES: To detail and evaluate all the techniques focused on wiring to achieve intubation of the distal tip of a microcatheter, balloon, or stent with an antegrade or retrograde guidewire, aiming to reduce complications by minimizing tension on fragile collaterals during externalization and enabling rapid antegrade conversion in various clinical scenarios. METHODS: We describe the two main techniques, tip-in and rendezvous, and their derivatives such a facilitated tip-in, manual MC-tip modification, tip-in the balloon, tip-in the stent, deep dive rendezvous, catch-it and antegrade microcatheter probing. We provide case studies that demonstrate the effectiveness of these techniques in complex scenarios involving extreme vessel angulation, severe calcification, fragile collaterals, and challenging retrograde MC crossing without externalization. CONCLUSION: The development of advanced variants along with traditional techniques to establish retrograde guidewire connection and antegrade conversion has led to the establishment of a cohesive group of methods known as portal techniques. These approaches serve as strategic advantages in retrograde CTO-PCI, providing a valuable and feasible alternative to conventional retrograde connection techniques, particularly when those techniques fail. Their ability to avoid the externalization process reduces potential damage to collateral channels and the ostium of the donor artery, potentially leading to a reduction in complication rates.

OBJECTIVES: Post-cardiotomy extracorporeal life support (ECLS) cannulation might occur in a general post-operative ward due to emergent conditions. Its characteristics have been poorly reported and investigated This study investigates the characteristics and outcomes of adult patients receiving ECLS cannulation in a general post-operative cardiac ward. METHODS: The Post-cardiotomy Extracorporeal Life Support (PELS) is a retrospective (2000-2020), multicenter (34 centers), observational study including adult patients who required ECLS for post-cardiotomy shock. This PELS sub-analysis analyzed patients´ characteristics, in-hospital outcomes, and long-term survival in patients cannulated for veno-arterial ECLS in the general ward, and further compared in-hospital survivors and non-survivors. RESULTS: The PELS study included 2058 patients of whom 39 (1.9%) were cannulated in the general ward. Most patients underwent isolated coronary bypass grafting (CABG, n = 15, 38.5%) or isolated non-CABG operations (n = 20, 51.3%). The main indications to initiate ECLS included cardiac arrest (n = 17, 44.7%) and cardiogenic shock (n = 14, 35.9%). ECLS cannulation occurred after a median time of 4 (2-7) days post-operatively. Most patients' courses were complicated by acute kidney injury (n = 23, 59%), arrhythmias (n = 19, 48.7%), and postoperative bleeding (n = 20, 51.3%). In-hospital mortality was 84.6% (n = 33) with persistent heart failure (n = 11, 28.2%) as the most common cause of death. No peculiar differences were observed between in-hospital survivors and nonsurvivors. CONCLUSIONS: This study demonstrates that ECLS cannulation due to post-cardiotomy emergent adverse events in the general ward is rare, mainly occurring in preoperative low-risk patients and after a postoperative cardiac arrest. High complication rates and low in-hospital survival require further investigations to identify patients at risk for such a complication, optimize resources, enhance intervention, and improve outcomes.

BACKGROUND: There are several types of LPC (long peripheral catheters) that vary in length, size, insertion method, and cost. The aim of the study was to evaluate whether ultrasonography can be useful for the selection of the suitable LPC in DIVA (difficult intravenous access) patients. METHODS: Based on the ultrasonographic examination, a long peripheral catheter was selected. A 6.4 cm LPC into a vein at a depth of up to 0.5 cm, a 8.5 cm LPC into a vein at a depth up to 1.5 cm, and a 9.8 cm catheter at a depth up to 2 cm using the cannula over needle method. A 12 cm catheter was inserted into the deeper veins using the direct Seldinger method. The catheter diameter was no more than 33% vein diameter. Dwell time and the number of complications of four vascular devices were recorded and compared. RESULTS: One thousand one hundred fifty-six patients, average age 76 years (19-102), 501 men and 655 women, were included in the study. Average dwelling time was 10 days (1-30), there were 136 complications (11.7%). A catheter 6.4 cm long was inserted in 346 (29.8%), 8.5 cm in 140 (12.1%), 9.8 cm in 320 (27, 5%), and 12 cm in 356 (30.6%) patients. There were no significant differences in dwelling time, rate, and type of complications among the four catheters used. CONCLUSION: Our results confirm that ultrasound examination can be useful for the selection of the suitable long peripheral catheter in DIVA patients.

AIMS: We report our single-centre experience of mid-term to long-term retrieval and reimplantation of a tine-based leadless pacemaker [Micra transcatheter pacing system (TPS)]. The TPS is a clinically effective alternative to transvenous single-chamber ventricular pacemakers. Whereas it is currently recommended to abandon the TPS at the end of device life, catheter-based retrieval may be favourable in specific scenarios. METHODS AND RESULTS: We report on nine consecutive patients with the implanted TPS who subsequently underwent transcatheter retrieval attempts. The retrieval system consists of the original TPS delivery catheter and an off-the-shelf single-loop 7 mm snare. The procedure was guided by fluoroscopy and intracardiac echocardiography. After an implantation duration of 3.1 ± 2.8 years (range 0.4-9.0), the overall retrieval success rate was 88.9% (8 of 9 patients). The mean procedure time was 89 ± 16 min, and the fluoroscopy time was 18.0 ± 6.6 min. No procedure-related adverse device events occurred. In the one unsuccessful retrieval, intracardiac echocardiography revealed that the TPS was partially embedded in the ventricular tissue surrounding the leadless pacemaker body in the right ventricle. After retrieval, three patients were reimplanted with a new TPS device. All implantations were successful without complications. CONCLUSION: A series of transvenous late retrievals of implanted TPS devices demonstrated safety and feasibility, followed by elective replacement with a new leadless pacing device or conventional transvenous pacing system. This provides a viable end-of-life management alternative to simple abandonment of this leadless pacemaker.

OBJECTIVE: This study aimed to evaluate the safety and performance of PowerPICC catheters in a real-world setting. DESIGN: Prospective, observational, multicentre study. SETTING: Nine European countries, involving 14 centres. PARTICIPANTS: General patient population. INTERVENTION: PowerPICC catheter inserted by the clinician as standard of care with routinely collected outcomes followed through device removal or 180 days postinsertion. PRIMARY AND SECONDARY OUTCOMES MEASURES: Safety and performance outcomes were assessed for PowerPICC, PowerPICC SOLO 2 and PowerGroshong PICC. The primary safety endpoint was the incidence of symptomatic venous thrombosis (VT), and secondary safety endpoints included phlebitis, extravasation, vessel laceration, vessel perforation local infection, accidental dislodgment and catheter-related bloodstream infection (CRBSI). The primary performance endpoint was the percentage of patients whose PowerPICC device remained in place through the completion of therapy. The secondary performance endpoints included catheter patency, placement success in a single attempt and usability. RESULTS: The enrolled patients (N=451) received either PowerPICC, PowerPICC SOLO 2 or PowerGroshong PICC catheters. Across all devices, 1.6% of patients developed symptomatic VT, and CRBSI occurred in 1.6% of patients. There were no cases of phlebitis or extravasation and only three cases of vein laceration or vein perforation. The catheters showed high success rates in completing therapy (81.8%), maintaining patency (93.9%) and achieving successful placement in a single attempt (90.4%). Clinicians overwhelmingly agreed that both the guidewire and stylet (93.3% and 94.4%, respectively) were easy or very easy to use. CONCLUSIONS: This study demonstrates the safety and performance of PowerPICC catheters across diverse settings and patient cohorts in real-world hospital settings across Europe. The findings indicate that these catheters are safe and can be effectively used in the general patient setting and when inserted by a variety of clinicians. The low incidence of complications and high success rates further support the clinical utility of these catheters. TRIAL REGISTRATION NUMBER: NCT04263649.

BACKGROUND: Patients with transposition of the great arteries (TGA) and systemic right ventricle often confront significant adverse cardiac events. The prognostic significance of invasive hemodynamic parameters in this context remains uncertain. Our hypothesis is that the aortic pulsatility index and hemodynamic profiling utilizing invasive measures provide prognostic insights for patients with TGA and a systemic right ventricle. METHODS: This retrospective multicenter cohort study encompasses adults with TGA and a systemic right ventricle who underwent cardiac catheterization. Data collection, spanning from 1994 to 2020, encompasses clinical and hemodynamic parameters, including measured and calculated values such as pulmonary capillary wedge pressure, aortic pulsatility index, and cardiac index. Pulmonary capillary wedge pressure and cardiac index values were used to establish 4 distinct hemodynamic profiles. A pulmonary capillary wedge pressure of ≥15 mm Hg indicated congestion, termed wet, while a cardiac index <2.2 L/min per m2 signified inadequate perfusion, labeled cold. The primary outcome comprised a composite of all-cause death, heart transplantation, or the requirement for mechanical circulatory support. RESULTS: Of 1721 patients with TGA, 242 individuals with available invasive hemodynamic data were included. The median follow-up duration after cardiac catheterization was 11.4 (interquartile range, 7.5-15.9) years, with a mean age of 38.5±10.8 years at the time of cardiac catheterization. Among hemodynamic parameters, an aortic pulsatility index <1.5 emerged as a robust predictor of the primary outcome, with adjusted hazard ratios of 5.90 (95% CI, 3.01-11.62; P<0.001). Among the identified 4 hemodynamic profiles, the cold/wet profile was associated with the highest risk for the primary outcome, with an adjusted hazard ratio of 3.83 (95% CI, 1.63-9.02; P<0.001). CONCLUSIONS: A low aortic pulsatility index (<1.5) and the cold/wet hemodynamic profile are linked with an elevated risk of adverse long-term cardiac outcomes in patients with TGA and systemic right ventricle.
