Project description:BackgroundLeft atrial appendage closure (LAAC) can be an alternative to oral anticoagulant therapy in patients with non-valvular atrial fibrillation, characterized by high risk of stroke (CHA2D2VASC ≥ two for men and CHA2D2VA2SC ≥ three for women) and high risk of bleeding (HASBLED = 3).Case summaryWe describe three case reports in which an intracardiac echocardiography probe was used via the oesophageal route as an alternative to traditional transoesophageal echocardiography (TEE) or ICE methods to guide LAAC. Guiding the procedure via conventional TEE, even if feasible, could be difficult in these patients due to different causes: one patient was affected by Brugada syndrome while the other two patients reported oropharyngeal abnormalities. For these reasons, we performed an alternative use of the ICE probe to guide the entire LAAC procedure.DiscussionCurrently, LAAC is performed using intracardiac or transoesophageal echocardiography. This alternative use of ICE probe via oesophageal (ICE-TEE) is reported in previous studies that describe the feasibility of this technique both in excluding the presence of thrombus in left atrial appendage before cardioversion and in guiding percutaneous foramen ovale closure. Therefore, the ICE probe has been used as an intraoperative transoesophageal echocardiographic probe to repair congenital heart disease in infants or children with oropharyngeal abnormalities.This case series reports the first use of ICE-TEE to guide the entire LAAC procedure, guaranteeing the visualization of all echocardiographic views needed to perform it. The present case series highlights the potential of ICE-TEE to safely perform both pre-procedural and intraoperative evaluations in LAAC procedure.

Project description:BackgroundPlacing an intracardiac echocardiogram (ICE) catheter in the left atrium allows for excellent visualization of the left atrial appendage to guide left atrial (LA) appendage occlusion (LAAO). Nonetheless, it requires a separate septal puncture or a unique set of skills to navigate the ICE through a previously prepared septal puncture, which can be challenging.Case summaryThis report describes a novel method to insert an ICE in the left atrium through a single septal puncture utilizing a snare technique. A 76-year-old male underwent LAAO by ICE guidance. After obtaining a standard atrial septal puncture, we were unable to advance the ICE into the left atrium. Therefore, we used a loop snare to grasp the ICE catheter-tip in the right atrium and direct it into the left atrium via the prepared septal puncture by tracking a pigtail wire that we routinely place as part of the procedure. Afterward, the left atrial appendage was successfully occluded with a Watchman device (Boston Scientific, Galway, Ireland), and the patient was discharged home without complications.DiscussionThe described technique could be a helpful tool for ICE placement to the left atrium in a controlled fashion, especially when challenging anatomy is encountered.

Project description:We aimed to determine the feasibility, efficacy, success, and safety of intracardiac echocardiography (ICE) in transcatheter multiple atrial septal defect (ASD) closure. Of 185 patients with multiple ASDs who underwent transcatheter closure, 140 (76%) patients who weighed <30kg with a narrow distance between defects or in whom single device closure was anticipated were guided by ICE and 45 patients were guided by three-dimensional (3D) transesophageal echocardiography (TEE) with or without ICE. Patients in the ICE group were relatively younger and weighed less than those in the 3D TEE group (p < 0.0001). The ratio of the distance between defects >7 mm was high, and more cases required ≥2 devices in the 3D TEE group than those in the ICE group (p < 0.0001). All patients in the 3D TEE group and seven patients (5%) in the ICE group were operated on under general anesthesia (p < 0.0001). The fluoroscopic time was shorter in the ICE group (13.98 ± 6.24 min vs. 24.86 ± 16.47 min, p = 0.0005). No difference in the complete closure rate and complications was observed. ICE-guided transcatheter and 3D TEE were feasible, safe, and effective in successful multiple ASD device closures, especially for young children and patients at high risk under general anesthesia.

Project description:BackgroundAn inferoposterior transseptal puncture (TSP) is generally recommended for percutaneous left atrial appendage (LAA) closure. However, the LAA is a highly variable anatomical structure. This may have an impact on the preferred TSP site.AimsThis study aimed to determine the optimal TSP site for percutaneous LAA closure in different LAA morphologies.MethodsIn this prospective study, 182 patients undergoing percutaneous LAA closure were included. The spatial relationship of the LAA to the fossa ovalis and its consequence for TSP was assessed at preprocedural cardiac computed tomography (CCT).ResultsBased on CCT analysis, it was predicted that coaxial alignment between the delivery sheath and the LAA would be obtained by an inferoposterior, inferocentral, or inferoanterior TSP in 75%, 16% and 8% of cases, respectively. This was also confirmed by procedural LAA angiogram in 175 cases (96%) with <30° angle between the delivery sheath and the LAA central axis. Multivariate logistic regression analysis identified reverse chicken wing LAA (odds ratio [OR] 6.36 [1.85-29.3]; p=0.005) and posterior bending of the proximal LAA (OR 17.2 [3.3-96.2]; p<0.001) as independent predictors of a central or anterior TSP - this to increase the chance of obtaining coaxial alignment between the delivery sheath and the LAA.ConclusionsAn inferoposterior TSP is recommended in the majority of percutaneous LAA closure procedures in order to obtain coaxial alignment between the delivery sheath and the LAA. An inferior but more central/anterior TSP should be recommended in case of a reverse chicken wing LAA or posterior bending of the proximal LAA, which occurs in 20-25% of cases.

Project description:BackgroundLeft atrial appendage closure (LAAC) is usually performed under the guidance of transesophageal echocardiography (TEE). Data on the safety of intracardiac echocardiogram (ICE)-guided LAAC from a real-world population in the United States remain limited. In this study, the aim was to evaluate the trends and outcomes of ICE-guided LAAC procedures using the US National Inpatient Sample.MethodsThis study used the National Inpatient Sample database from quarter 4 of 2015 to 2019. We used a propensity-matched analysis and adjusted odds ratios for in-hospital outcomes/complications. A P value of <.05 was considered significant.ResultsWe identified 61,995 weighted LAAC cases. Of these, 1410 patients had ICE-guided LAAC with a lower median age than the patients who had TEE-guided LAAC (75 vs 77 years; P ≤ .01). The use of ICE-guided LAAC increased from 1.7% in 2015 to 2.2% in 2019 (P trend = .75). Major, cardiovascular, neurologic, and pulmonary complications were similar for ICE-guided and TEE-guided LAAC on adjusted analysis. On propensity-matched analysis, the overall vascular complication rates were similar. However, retroperitoneal bleeding remained significantly higher (0.7% vs 0%) with ICE. Gastrointestinal bleeding complications were more frequent in TEE-guided LAAC (3.5% vs 2.1%). The length of stay was similar for both groups (median = 1 day; P = .23); however, ICE was associated with $1769 excess cost of hospitalization ($25,112 vs $23,343; P = .04).ConclusionsICE-guided LAAC is safer than TEE-guided LAAC, with similar rates of major complications. However, ICE use was associated with lower rates of gastrointestinal bleeding and higher rates of retroperitoneal bleeding. In addition, ICE-guided LAAC is associated with a similar length of stay but higher costs of hospitalization.

Project description:BackgroundAn 82-year-old female with a history of atrial fibrillation and repeated episodes of major bleeding on direct oral anticoagulant therapy, with a high risk for thromboembolism and was referred for left atrial appendage closure.Case summaryDuring the procedure, an unrecognized puncture of the aorta by the transseptal puncture (TSP) needle and inadvertent advancement of the sheath resulted in ascending aorta perforation. This perforation was closed percutaneously using an Amplatzer™ Duct Occluder (ADO). Reversal of heparinization with protamine sulphate was given to avoid intractable bleeding. However, this resulted in thrombus formation and subsequent embolization causing an ST-elevation myocardial infarction. This was treated with balloon dilatation and thrombus aspiration with subsequent Thrombolysis in Myocardial Infarction 3 flow.DiscussionInadvertent ascending aorta perforation is a rare yet serious complication that can occur during TSP. Percutaneous closure using an ADO is a viable management option. The reversal of heparin carries a risk of thrombus formation and should be avoided in cases where there is no evidence of overt bleeding.

Project description:BackgroundTranscatheter mitral valve-in-valve implantation (MVIV) has emerged as a viable treatment option in patients at high risk for surgery. Occasionally, despite appropriate puncture location and adequate dilation, difficulty is encountered in advancing the transcatheter heart valve across interatrial septum.Case summaryWe describe a case of a 79-year-old woman with severe chronic obstructive pulmonary disease (COPD), prior surgical bioprosthetic aortic and mitral valve replacement implanted in 2007, atrial fibrillation, and Group II pulmonary hypertension who presented with progressively worsening heart failure symptoms secondary to severe bioprosthetic mitral valve stenosis and moderate-severe mitral regurgitation. Her symptoms had worsened over several months, with multiple admissions at other institutions with treatment for both COPD exacerbation and heart failure. Transoesophageal echocardiogram demonstrated preserved ejection fraction, normal functioning aortic valve, and dysfunctional mitral prosthesis with severe stenosis (mean gradient 13 mmHg) and moderate-severe regurgitation. After a multi-disciplinary heart team discussion, the patient underwent a transcatheter MVIV implantation. During the case, inability in advancing the transcatheter heart valve (THV) across interatrial septum despite adequate septal balloon pre-dilation was successfully managed with the support of a stiff 'buddy wire' anchored in the left upper pulmonary vein using the same septal puncture. The patient tolerated the procedure well and was discharged home.DiscussionOperators should be aware of potential strategies to advance the THV when difficulty is encountered in crossing the atrial septum despite adequate septal preparation. One such strategy is the use of stiff 'buddy wire' for support which avoids the need for more aggressive septal dilatation.

Project description:ObjectivesThis study aimed to assess the rate of difficult interatrial septum (IAS) crossing with the intracardiac echocardiography (ICE) probe during percutaneous left atrial appendage (LAA) closure and to identify techniques that facilitate IAS crossing with the ICE probe.BackgroundPercutaneous LAA closure is increasingly performed by ICE guidance. Although such an approach omits the need for general anesthesia, crossing of the IAS with the ICE probe may sometimes be challenging.MethodsAll consecutive patients that underwent ICE-guided percutaneous LAA closure with an Amplatzer Amulet (Abbott) or WatchmanFLX (Boston Scientific) at our center in the period 2018-2021 were included. Cases in which IAS crossing with ICE was difficult were identified and techniques used to facilitate IAS crossing were identified and listed.ResultsIn 17 (5%) out of 354 cases, IAS crossing with the ICE probe was difficult and required use of additional techniques. Ultimately, IAS crossing was also successful in these 17 cases by using one of three possible facilitation techniques: the probing technique (12 cases), the double-wire technique (3 cases), and the snaring technique (2 cases). In one case, the double-wire technique was converted to the snaring technique, as crossing of the ICE probe remained challenging despite the use of two stiff guidewires.ConclusionCrossing of the IAS with the ICE probe can be challenging in 5% of ICE-guided percutaneous LAA closure procedures. Operators should be aware of possible facilitation techniques in challenging cases, as these show to be safe and effective.
