Steam pop (SP) during radiofrequency catheter ablation (RFCA) for pulmonary vein isolation (PVI) may cause cardiac perforation, which may require drainage and emergent thoracotomy or even lead to death. Data investigating the timely detection of the occurrence of “silent” or “nonaudible” SP events are limited. <i>Methods and Results</i>. A total of 516 consecutive atrial fibrillation (AF) patients who underwent index PVI were included in this retrospective observational study. The duration, power, impedance, temperature, and contact force (CF) of RFCA were continually monitored and recorded throughout the procedure. A total of 15 (2.9%) audible SP events occurred in 14 patients; 2 of the patients developed pericardial tamponade, 1 patient underwent drainage, and 1 patient underwent emergent thoracotomy. The time from RFCA initiation to the occurrence of audible SP was 19.4 ± 6.9 s. Abrupt temperature change occurred in 13 (86.7%) of the 15 SP events, of which 8 (53.3%) exhibited an abrupt temperature rise of 2.3 ± 1.0°C, 5 (33.3%) exhibited an abrupt temperature drop of 2.3 ± 1.3°C, and 2 (13.3%) exhibited no discernible temperature change. <i>Conclusions</i>. In conclusion, simultaneously recorded spike potentials and abrupt impedance rise with concomitant temperature and/or CF change could be a feasible method for the timely detection of the occurrence of audible, “silent,” or “nonaudible” SP events, particularly in regions where the risk of perforation may be of concern.</p>\u0000 </div>","PeriodicalId":16329,"journal":{"name":"Journal of interventional cardiology","volume":"2023 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10098411/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9310025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the efficacy of the “<i>L</i>-sandwich” strategy, which involves the implantation of stents in the main vessel (MV) and shaft of the side branch (SB) with a drug-coated balloon (DCB) applied to the SB ostium, for coronary true bifurcation lesions. <i>Methods and Results</i>. Of 99 patients with true bifurcation lesions, 38 patients underwent the “<i>L</i>-sandwich” strategy (group <i>A</i>), 32 patients underwent a two-stent strategy (group <i>B</i>), and 29 patients underwent a single-stent + DCB strategy (group <i>C</i>). Angiography outcomes (late lumen loss [LLL], minimum lumen diameter [MLD]), and clinical outcomes (major adverse cardiac events [MACEs]) were analyzed. At 6 months, the MLD of the SB ostium in groups <i>A</i> and <i>B</i> were similar (<i>P</i> &gt; 0.05) and group <i>A</i> larger than group <i>C</i> (<i>P</i> &lt; 0.05). The LLL of group <i>B</i> was the largest among the three groups (<i>P</i> &lt; 0.05). The MLD of the SB shaft in groups <i>A</i> and <i>B</i> were larger than in group <i>C</i> (<i>P</i> &lt; 0.05).

We aimed to assess the effectiveness of the sheathless Eaucath guiding catheter (SEGC) in overcoming severe spasm. <i>Background</i>. Radial spasm is a frequent challenge in transradial access (TRA) and can be difficult to manage. <i>Methods</i>. We performed a prospective observational study of 1000 consecutive patients undergoing coronary angiography with or without percutaneous coronary intervention. Patients with primary transfemoral access (TFA) or primary use of a sheathless guide catheter were excluded. Patients who developed angiographically confirmed severe spasm were treated with further sedation and vasodilators. If the conventional catheter would still not advance, it was exchanged for a SEGC. The primary endpoint was the successful passage of the SEGC through the radial with successful engagement of the coronary artery in patients with resistant severe spasm. <i>Results</i>. Primary TFA access was used in 58 (5.8%) and primary radial access with a SEGC in 44 (4.4%) patients. Of the remaining 898 patients, 888 (98.9%) had a radial sheath successfully inserted. Of these, 49 (5.5%) developed severe radial spasm with inability to advance the catheter. Following treatment with additional sedation and vasodilators, the severe spasm resolved in 5 (10.2%) patients.

Evidence regarding the impact of prophylactic implantation of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for elective high-risk percutaneous coronary intervention (PCI) is limited. The purpose of this paper is to evaluate the outcome during index hospitalization and 3 years after interventions. <i>Methods</i>. This is an observational retrospective study including all patients undergoing elective, high-risk PCI and receiving VA-ECMO for cardiopulmonary support. Primary endpoints were in-hospital and 3- year major adverse cardiovascular and cerebrovascular event (MACCE) rates. Secondary endpoints were vascular complications, bleeding, and procedural success. <i>Results</i>. Nine patients were included in total. All patients were considered inoperable by the local heart team, and 1 patient had a previous coronary artery bypass graft (CABG). All patients were hospitalized for an acute heart failure episode 30 days before the index procedure. Severe left ventricular dysfunction was present in 8 patients. The main target vessel was the left main coronary artery in 5 cases. Complex PCI techniques were used: bifurcations with 2 stents in 8 patients, rotational atherectomy was performed in 3, and coronary lithoplasty in 1 case. PCI was successful in all of the patients with revascularization of all target and additional lesions. Eight of the 9 patients survived for at least 30 days after the procedure, and 7 patients survived for 3 years after the procedure. Regarding the complication rate, 2 patients suffered from limb ischemia and were treated by an antegrade perfusion, 1 patient had a femoral perforation that needed surgical repair, 6 patients had a hematoma, 5 patients had a significant drop in hemoglobin of more than 2 g/dl and received blood transfusions, 2 patients were treated for septicemia, and 2 patients needed hemodialysis. <i>Conclusions</i>. Prophylactic use of VA-ECMO in elective patients is an acceptable strategy for revascularization by high-risk coronary percutaneous interventions with good long-term outcomes for patients considered inoperable when a clear clinical benefit is expected. Regarding the potential risk of complications due to a VA-ECMO system, the selection of candidates in our series was based on a multiparameter analysis. The two main triggers in favor of prophylactic VA-ECMO in our studies were the presence of a recent heart failure episode and the high probability of periprocedural prolonged impairment of the coronary flow through the major epicardial artery.</p>\u0000 </div>","PeriodicalId":16329,"journal":{"name":"Journal of interventional cardiology","volume":"2023 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9922177/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10727517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine if radial artery (RA) access compared with femoral artery (FA) access for percutaneous coronary intervention (PCI) is associated with a lower incidence of acute kidney injury (AKI). <i>Background</i>. AKI results in substantial morbidity and cost following PCI. Prior studies comparing the occurrence of AKI associated with radial artery (RA) versus femoral artery (FA) access have mixed results. <i>Methods</i>. Using a large state-wide database, 14,077 patients (8,539 with RA and 5,538 patents with FA access) were retrospectively compared to assess the occurrence of AKI following PCI. To reduce selection bias and balance clinical data across the two groups, a novel machine learning method called a Generalized Boosted Model was conducted on the arterial access site generating a weighted propensity score for each variable. A logistic regression analysis was then performed on the occurrence of AKI following PCI using the weighted propensity scores from the Generalized Boosted Model. <i>Results</i>. As shown in other studies, multiple variables were associated with an increase in AKI after PCI. Only RA access (OR 0.82; 95% CI 0.74–0.91) and male gender (OR 0.80; 95% CI 0.72–0.89) were associated with a lower occurrence of AKI.

Nowadays, transcatheter device closure of an atrial septal defect (ASD) is a standard approach in children. Potential early and long-term side effects or complications related to the metal framework of the devices are a known issue. A bioresorbable device such as the Carag Bioresorbable Septal Occluder™ (CBSO) could resolve such complications. <i>Material and Results</i>. The Carag Bioresorbable Septal Occluder™ (CBSO; Carag AG, Baar, Switzerland) is a self-centering double disk, repositionable, and retractable device with a bioresorbable framework (polylactic-co-glycolic acid), which is almost completely resorbed by 18–24 months postimplantation. This manuscript reports the four first-in-child ASD device closures using a CBSO. The patients’ age was median (IQ1-IQ3), 4.5 years (4–7.25). Weight was 21.3 kg (17.6–32.7). We demonstrated procedural feasibility and safety. Effective defect closure with the device was 100%. Echocardiographic measurements of the thickness of the interatrial septum did not show any relevant increase over a 12-monthfollow-up period. There were no residual defects found after the procedure or later during the resorption process. The patients showed no evidence of any local or systemic inflammatory reaction. <i>Conclusions</i>.
