A Safety and Feasibility Single-Arm Study of a Novel Catheter Thrombectomy Device for the Treatment of Pulmonary Embolism (ENGULF).

Background: Despite advances in therapy options, pulmonary embolism (PE) continues to carry a high risk of mortality and morbidity. Currently, therapeutic options are limited with only 2 US Food and Drug Administration-cleared catheter-based embolectomy devices approved for the treatment of intermediate-risk PE. The novel Helo PE thrombectomy catheter (Endovascular Engineering, Inc) has a flexible and collapsible funnel with an internal agitator for a dual mechanism of treatment for acute PE. We sought to investigate the safety and feasibility of the novel Helo PE thrombectomy catheter in intermediate-risk PE. Methods: A prospective, single-arm feasibility study evaluating the Helo PE catheter was performed in patients presenting with intermediate-risk PE. Patients underwent preprocedural and postprocedural computed tomography angiography. Primary efficacy was the difference in preprocedural to postprocedural right ventricle/left ventricle (RV/LV) ratio. Primary and secondary safety outcomes were all-cause mortality, major life-threatening bleeding, device-related serious adverse events, pulmonary or cardiac injury, and clinical decompensation at 48 hours postprocedure and at 30 days. Results: A total of 25 patients from 8 centers were consented and included in the analysis. Preprocedural computed tomography angiography revealed an RV/LV ratio of 1.53 ± 0.27. All patients underwent a successful thrombectomy procedure. Postprocedure, the RV/LV ratio was reduced to 1.15 ± 0.18, translating into a 23.2 ± 12.81% decrease from baseline. No patients underwent adjunctive thrombolysis. Two patients had adjunctive catheter-directed embolectomy with an alternative device. Two patients had postprocedural anemia requiring transfusion but did not meet criteria for major life-threatening bleeding by VARC-2 criteria. There were no major adverse events including no deaths, major bleeding, pulmonary injury, or vascular complications at 48 hours or 30 days post procedure. Conclusions: In this multicenter first-in-human study, use of the Helo PE thrombectomy catheter was feasible and safe for the treatment of acute PE.

The Effect of Time Pressure on Motion Economy and Smoothness of Interventional Radiology Trainee Performance in Simulated Central Venous Line Placement.

PURPOSE: To evaluate the effect of being under time pressure on procedural performance using hand motion analysis. MATERIALS AND METHODS: Eight radiology trainees performed central venous access on a phantom while recording video and hand motion data using an electromagnetic motion tracker. Each trainee performed the procedure six times: the first three trials without any prompts (control), while for the next three, they were asked to perform the task as fast as possible (time pressure). Validated hand motion metrics were analyzed, and two blinded and independent evaluators rated procedural performance using a previously validated task-specific global rating scale (GRS). Motion/time ratios and linear mixed-effect methods were used to control for time, and constants for both strategies were compared. RESULTS: Hand motion analysis showed that trainees completed the simulated procedure faster under time pressure (46 ± 18 s vs. 56 ± 27 s, p = 0.008) than during the control strategy. However, when controlling for time, trainees moved their hands 79 more centimeters (p = 0.04), made 15 more translational movements (p = 0.003) and 18 more rotational movements (p = 0.01) when under time pressure compared to at their own pace. CONCLUSION: Although trainees could perform the procedure faster under time pressure, there was a deterioration in hand motion economy and smoothness. This suggests that hand motion metrics offer a more comprehensive assessment of technical performance than time alone.

Analyzing the Evolution of Needle and Ultrasound Probe Manipulation Skills of Interventional Radiology Trainees With Time and Experience.

PURPOSE: To test the hypothesis that hand motion analysis can measure the progression of needle and ultrasound probe manipulation skills of interventional radiology trainees in central venous line placement. MATERIALS AND METHODS: An expert cohort of 6 interventional radiologists and 4 anesthesiologists and a trainee cohort of 6 novice trainees (<50 central lines) and 5 experienced trainees (>50 central lines) performed simulated central venous access. Four novices and 1 experienced trainee repeated the task 1 year later. An electromagnetic motion tracking system tracked the needle hand and ultrasound probe. Path length, translational, and rotational movements were calculated separately for the needle hand and probe sensor. These metrics were used to calculate motion metrics based scores on a scale of 0 to 3 for each sensor. Nonparametric statistics were used, and the data are reported as median ± interquartile range. RESULTS: Comparing novice and experienced trainees, there was a significant difference in probe scores (experienced vs. novice: 1 ± 2 vs. 0 ± 0, P = 0.04) but not in needle-hand scores (1 ± 1.5 vs. 0 ± 1, P = 0.26). Trainees showed a significant increase in probe scores at the 1-year follow-up (baseline vs. follow-up: 0 ± 1 vs. 2.5 ± 1.8, P = 0.003), but no significant difference was observed in the needle manipulation metrics. Experts differed significantly from experienced trainees for all metrics for both sensors (P < 0.05), with the exception of the path length of the probe. CONCLUSIONS: Acquisition of improved dexterity of the probe may occur before improvement in the dexterity with the needle hand for interventional radiology trainees.

Efficacy and Safety of Radiation Segmentectomy with 90Y Resin Microspheres for Hepatocellular Carcinoma.

Background Limited data are available on radiation segmentectomy (RS) for treatment of hepatocellular carcinoma (HCC) using yttrium 90 (90Y) resin microsphere doses determined by using a single-compartment medical internal radiation dosimetry (MIRD) model. Purpose To evaluate the efficacy and safety of RS treatment of HCC with 90Y resin microspheres using a single-compartment MIRD model and correlate posttreatment dose with outcomes. Materials and Methods This retrospective single-center study included adult patients with HCC who underwent RS with 90Y resin microspheres between July 2014 and December 2022. Posttreatment PET/CT and dosimetry were performed. Adverse events were assessed using the Common Terminology Criteria for Adverse Events, version 5.0. Per-lesion and overall response rates (ie, complete response [CR], objective response, disease control, and duration of response) were assessed at imaging using the Modified Response Evaluation Criteria in Solid Tumors, and overall survival (OS) was assessed using Kaplan-Meier analysis. Results Among 67 patients (median age, 69 years [IQR, 63-78 years]; 54 male patients) with HCC, median tumor absorbed dose was 232 Gy (IQR, 163-405 Gy). At 3 months, per-lesion and overall (per-patient) CR was achieved in 47 (70%) and 41 (61%) of 67 patients, respectively. At 6 months (n = 46), per-lesion rates of objective response and disease control were both 94%, and per-patient rates were both 78%. A total of 88% (95% CI: 79 99) and 72% (95% CI: 58, 90) of patients had a per-lesion and overall duration of response of 1 year or greater. At 1 month, a grade 3 clinical adverse event (abdominal pain) occurred in one of 67 (1.5%) patients. Median posttreatment OS was 26 months (95% CI: 20, not reached). Disease progression at 2 years was lower in the group that received 300 Gy or more than in the group that received less than 300 Gy (17% vs 61%; P = .047), with no local progression in the former group through the end of follow-up. Conclusion Among patients with HCC who underwent RS with 90Y resin microspheres, 88% and 72% achieved a per-lesion and overall duration of response of 1 year or greater, respectively, with one grade 3 adverse event. In patients whose tumors received 300 Gy or more according to posttreatment dosimetry, a disease progression benefit was noted. © RSNA, 2024 Supplemental material is available for this article.

Improving Compliance with Preoperative Nasal Povidone-Iodine to Prevent Surgical Site Infection in Vascular and Neurosurgery Services in a Community Teaching Hospital.

Surgical site infections (SSI) remain a cause of morbidity, prolonged hospitalization, surgical readmission, and death. Nasal colonization with methicillin-resistant Staphylococcal aureus is a frequent cause of device-related SSI and nasal mupirocin has been used for prevention. More recently, povidone-iodine nasal swabs have become an alternative. It is cheaper, ensures compliance and there are no concerns regarding antimicrobial resistance. However, its adoption was suboptimal in a community hospital system in southwestern Ohio, especially in neurosurgery and vascular surgery. Quality improvement techniques, including solicitation of stakeholder input, surgeons and perioperative nurses' education, and the use of reminders to order and administer the povidone-iodine nasal swabs improved physician ordering and nurse administration compliance, leading to fewer infections. The interventions continued after the project was completed, sustaining decreases in neurosurgery and vascular surgery, and fewer SSI through the first years of the pandemic. Despite the complexity of these surgeries, simple interventions were effective in addressing the problem.

Angiography with cone-beam CT versus contrast-enhanced MRI for living donor transplant imaging: Is MRI enough?

The purpose of this study is to compare the subjective and objective quality and confidence between conventional angiography with cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) for the preoperative evaluation of potential donors for living donor liver transplant. Seventeen patients undergoing preoperative donor evaluation for living donor liver transplantation that underwent angiography with CBCT and contrast-enhanced MRI for evaluation of hepatic vascular anatomy were included in the study. Four attending radiologists interpreted anonymized, randomized angiography with CBCT images and MRIs, rating the diagnostic quality and confidence of their interpretation (on a 3-point scale) for each element, as well as clinically relevant measurements. Overall, the readers rated the quality of angiography with CBCT to be higher than that of MRI (median [interquartile range] = 3 (2, 3) vs. 2 (1-3), p < 0.001) across all patients. Readers of angiography with CBCT had more confidence in their interpretations as an average of all elements evaluated than the MRI readers (3 (3) vs. 3 (2, 3), p < 0.001). When the same reader interpreted both MRI and CBCT, the right hepatic artery diameter (3.8 mm ± 0.72 mm vs. 4.5 mm ± 1.2 mm, p < 0.005) and proper hepatic artery diameter (4.43 mm ± 0.98 mm vs. 5.4 mm ± 1.05 mm, p < 0.003) were significantly different between MRI and CBCT. There was poor interrater reliability for determining segment IV arterial supply for both modalities (κ < 0.2). Angiography with CBCT provides higher subjective diagnostic quality and greater radiologist confidence than MRI. The difference in measurements between CBCT and MRI when the same reader reads both studies suggests CBCT adds additional information over MRI evaluation alone.

Association between Patient Experience Scores and Low Utilization of Hepatocellular Carcinoma Treatment in the United States: A Surveillance, Epidemiology, and End Results-Consumer Assessment of Healthcare Providers and Systems Analysis (SEER-CAHPS).

PURPOSE: To study the experiences of patients with hepatocellular carcinoma (HCC) contributing to treatment discrepancy in the United States. MATERIALS AND METHODS: Using Surveillance, Epidemiology, and End Results data from National Cancer Institute (NCI), Medicare (2002-2015) beneficiaries with HCC who completed a Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey were included. Six CAHPS items (3 global scores: global care rating [GCR], primary doctor rating [PDR], and specialist rating [SR]; 3 composite scores: getting needed care [GNC], getting care quickly [GCQ], and doctor communication [DC]) assessed patient experience. Covariates assessed between treated and nontreated groups included patient, disease, hospital, and CAHPS items. RESULTS: Among 548 patients with HCC, 211 (39%) received treatment and 337 (61%) did not receive treatment. Forty-two percent (GCR), 29% (PDR), 30% (SR), 36% (GNC), 78% (GCQ), and 35% (DC) of patients reported less-than-excellent experiences on the respective CAHPS items. Chronic liver disease (CLD) was present in 52% and liver decompensation (LD) in 60%. A minority of the hospitals were NCI-designated cancer centers (47%), transplant centers (27%), and referral centers (9%). On univariable analysis, patients with at least a high school degree (odds ratio [OR], 1.9), admittance to a ≥400-bed hospital (OR, 2.7), CLD (OR, 3.0), or LD (OR, 1.7) were more likely to receive treatment, whereas older patients (≥75 years) (OR, 0.5) were less likely to receive treatment. On multivariable, patients with CLD (OR, 6.8) and an excellent experience in GNC with a specialist (OR, 10.6) were more likely to receive treatment. CONCLUSIONS: HCC treatment discrepancy may be associated with patient-related factors, such as lack of specialist care (GNC), and disease-related factors, such as absence of underlying CLD.

Evaluation of Primary Lymphedema with Intranodal Lymphangiography.

PURPOSE: There are limited existing data on the lymphatic anatomy of patients with primary lymphedema (LED), which is caused by aberrant development of lymphatic channels. In addition, there is a paucity of contemporary studies that use groin intranodal lymphangiography (IL) to evaluate LED anatomy. The purpose of this retrospective observational study was to better delineate the disease process and anatomy of primary LED using groin IL. MATERIALS AND METHODS: We identified common groin IL findings in a cohort of 17 primary LED patients performed between 1/1/2017 and 1/31/2022 at a single institution. These patients were clinically determined to have primary lymphedema and demonstrated associated findings on lower extremity MR and lymphoscintigraphy. RESULTS: Ten patients (59%) demonstrated irregular lymph node morphology or a paucity of lymph nodes on the more symptomatic laterality. Eight patients (47%) demonstrated lymphovenous shunting from pre-existing anastomoses between the lymphatic and venous systems. Eight patients (47%) demonstrated passage of contrast past midline to the contralateral lymphatics. Finally, 12 patients (71%) failed to opacify the cisterna chyli and thoracic duct on their initial lymphangiograms. Delayed computed tomography of 3 patients showed eventual central lymphatic opacification up to the renal veins, but none of these patients showed central lymphatic opacification to the thorax. CONCLUSION: This descriptive, exploratory study demonstrates common central groin IL findings in primary LED to highlight patterns interventional radiologists should identify and report when addressing primary LED.

The Impact of Implementation of a Commercial Inferior Vena Cava Filter Database Program on Filter Retrieval versus Physician Tracking over a 9-Year Period: A Retrospective, Observational Study.

PURPOSE: To compare the impact of a commercial tracking database on inferior vena cava filter retrievals with that of physician tracking and no tracking. MATERIALS AND METHODS: From January 2013 to December 2021, 532 filters were placed at a single institution and followed in 3 phases: (a) Phase 1, pretracking (January 1, 2013, to February 28, 2015); (b) Phase 2, commercial database tracking (March 1, 2015, to June 30, 2019); and (c) Phase 3, commercial database tracking with separate tracking by an interventional radiologist (July 1, 2019, to December 31, 2021). Patients excluded from the commercial database due to human error served as a control group. Outcomes of commercial database entry, 2-year filter retrieval rates, dwell times, and factors contributing to retrieval candidacy were collected. RESULTS: Two-year retrieval rates in Phases 1, 2 and 3 were 20%, 31%, and 46%, respectively (Phase 1 vs 2, P = .04; Phase 2 vs 3, P = .009). Median dwell times across Phases 1, 2, and 3 were 168 days (4-1,313 days), 140 days (3-1,988 days), and 188 days (13-734 days) (P = .33), respectively. There was no difference in retrieval rates (P = .86) and dwell times (P = .50) between patients enrolled in the database group and those enrolled in the control group. Across all phases, 48% of patients enrolled in the database were not successfully contacted, and only 6% were categorized as "likely to consult" filter retrieval. During Phase 3, 100% of patients achieved a retrieval disposition. CONCLUSIONS: A commercial tracking database had low success rates of contacting patients and did not increase filter retrieval rates relative to those in the control group; however, physician tracking increased retrieval rates.

Evaluation of Technical Performance of Ultrasound-Guided Procedures through Hand Motion Analysis: An Exploration of Motion Metrics.

PURPOSE: To evaluate the ability of hand motion analysis using conventional and new motion metrics to differentiate between operators of varying levels of experience for central venous access (CVA) and liver biopsy (LB). MATERIALS AND METHODS: In the CVA task, 7 interventional radiologists (experts), 10 senior trainees, and 5 junior trainees performed ultrasound-guided CVA on a standardized manikin; 5 trainees were retested after 1 year. In the LB task, 4 radiologists (experts) and 7 trainees biopsied a lesion on a manikin. Conventional motion metrics (path length and task time), a refined metric (translational movements), and new metrics (rotational sum and rotational movements) were calculated. RESULTS: In the CVA task, experts outperformed trainees on all metrics (P < .02). Senior trainees required fewer rotational movements (P = .02), translational movements (P = .045), and time (P = .001) than junior trainees. Similarly, on 1-year follow-up, trainees had fewer translational (P = .02) and rotational (P = .003) movements with less task time (P = .003). The path length and rotational sum were not different between junior and senior trainees or for trainees on follow-up. Rotational and translational movements had greater area under the curve values (0.91 and 0.86, respectively) than the rotational sum (0.73) and path length (0.61). In the LB task, experts performed the task with a shorter path length (P = .04), fewer translational (P = .04) and rotational (P = .02) movements, and less time (P < .001) relative to the trainees. CONCLUSIONS: Hand motion analysis using translational and rotational movements was better at differentiating levels of experience and improvement with training than the conventional metric of path length.

Transjugular Intrahepatic Portosystemic Shunt and Thrombectomy (TIPS-Thrombectomy) for Symptomatic Acute Noncirrhotic Portal Vein Thrombosis.

PURPOSE: To report the safety and effectiveness of transjugular intrahepatic portosystemic shunt and mechanical thrombectomy (TIPS-thrombectomy) for symptomatic acute noncirrhotic portal vein thrombosis (NC-PVT). MATERIALS AND METHODS: Patients with acute NC-PVT who underwent TIPS-thrombectomy between 2014 and 2021 at a single academic medical center were retrospectively reviewed. Thirty-two patients were included (men, 56%; median age, 51 years [range, 39-62 years]). The causes for PVT included idiopathic (n = 12), prothrombotic disorders (n = 11), postsurgical sequelae (n = 6), pancreatitis (n = 2), and Budd-Chiari syndrome (n = 1). The indications for TIPS-thrombectomy included refractory abdominal pain (n = 14), intestinal venous ischemia (n = 9), ascites (n = 4), high-risk varices (n = 3), and variceal bleeding (n = 2). Variables studied included patient, disease, and procedure characteristics. Patients were monitored over the course of 1-year follow-up. RESULTS: Successful recanalization of occluded portal venous vessels occurred in all 32 patients (100%). Compared with pretreatment patency, recanalization with TIPS-thrombectomy resulted in an increase in patent veins (main portal vein [28% vs 97%, P < .001], superior mesenteric vein [13% vs 94%, P < .001], and splenic vein [66% vs 91%, P < .001]). Three procedure-related adverse events occurred (Society of Interventional Radiology grade 2 moderate). Hepatic encephalopathy developed in 1 (3%) of 32 patients after TIPS placement. At 1-year follow-up, return of symptoms occurred in 3 (9%) of 32 patients: (a) ascites (n = 1), (b) variceal bleeding (n = 1), and (c) intestinal venous ischemia (n = 1). The intention-to-treat 1-year portal vein and TIPS primary and secondary patency rates were 78% (25/32) and 100% (32/32), respectively. Seven patients required additional procedures, and the 1-year mortality rate was 3% (1/32). CONCLUSIONS: TIPS-thrombectomy is a safe and effective method for treating patients with symptomatic acute NC-PVT.

Motion Analysis: An Objective Assessment of Special Operations Forces and Tactical Medics Performing Point-of-Care Ultrasound.

BACKGROUND: Point-of-care ultrasound (POCUS) is commonly employed to image the heart, lungs, and abdomen. Rapid ultrasound for shock and hypotension (RUSH) exams are a critical component of POCUS employed in austere environments by Special Operations Forces (SOF) and tactical medics for triage and diagnosis. Despite its utility, training for POCUS remains largely unstandardized with respect to feedback and markers of proficiency. We hypothesized that motion analysis could objectively identify improvement in medics' performance of RUSH exams. Furthermore, we predicted that motion metrics would correlate with qualitative ratings administered by attending anesthesiologists. METHODS: A team of civilian and military attending anesthesiologists trained 24 medics in POCUS during a 5-day course. Each medic performed eight RUSH exams using an ultrasound probe equipped with an electromagnetic motion sensor to track total distance travelled (path length), movements performed (translational motions), degrees rotated (rotational sum), and time. Instructors (experts) observed and rated the exams on the following items: image finding, image fine-tuning, speed, final image accuracy, and global assessment. Motion metrics were used to provide feedback to medics throughout the course. Generalized estimating equations were used to analyze the trends of motion metrics across all trials. Correlations amongst motion metrics and expert ratings were assessed with Pearson correlation coefficients. RESULTS: Participants exhibited a negative trend in all motion metrics (p < 0.001). Pearson correlation coefficients revealed moderate inverse correlations amongst motion metrics and expert ratings. CONCLUSION: Motion analysis was able to quantify and describe the performance of medics training in POCUS and correlated with expert ratings.

Patient and Provider Perspectives of Telehealth and In-Person Interventional Radiology Clinic Visits.

PURPOSE: To assess patient and provider satisfaction with interventional radiology (IR) outpatient telehealth and in-person clinic. MATERIALS AND METHODS: This institutional review board-approved study analyzed patient satisfaction with clinic via survey after an IR outpatient telehealth or in-person visit. A physician telehealth experience survey was completed by 8 IR physicians. RESULTS: During the initial survey period, 44 (83%) of 53 patients completed a survey via telephone compared with 37 (23%) of 158 patients who were offered an electronic survey during the second survey period. Of 81 respondents, 18 (22%) were in-person and 63 (78%) were via telehealth. Of the respondents, nearly all patients (97%) in the telehealth group reported satisfaction with their telehealth clinic visit, with similar rates of high patient satisfaction between in-person and telehealth visits (P = .51). Most patients (98%) in the telehealth group strongly agreed that their physician's recommendations were clear in the telehealth visit and that their visit was private, similar to in-person visits (P = .13). A telehealth visit saved time for all patients (100%), with 78% reporting >1 hour of time-saving. All IR physicians (n = 8) reported greater efficiency with telehealth clinic than with in-person clinic and that follow-up patterns would change if telehealth was available. However, all providers (100%) found telephone visits less satisfying than in-person visits, with video visits being either equally satisfying (71%) or less satisfying (29%). CONCLUSIONS: Patient satisfaction with the in-person and telehealth outpatient IR clinic was high, with patients and providers reporting time-saving and greater efficiency with telehealth, suggesting that telehealth should remain an important component of outpatient IR clinic care.

Assessing Skill Acquisition in Anesthesiology Interns Practicing Central Venous Catheter Placement Through Advancements in Motion Analysis.

OBJECTIVES: The study authors hypothesized that a combination of previously used (path length, translational motions, and time) and novel (rotational sum) motion metrics could be used to analyze learning curves of anesthesiology interns (postgraduate year 1) practicing central venous catheter placement in the simulation setting. They also explored the feasibility of using segmented motion recordings to inform deliberate practice. DESIGN: A prospective cohort study. SETTING: A single academic medical center. PARTICIPANTS: Anesthesiology interns (postgraduate year 1). INTERVENTIONS: Anesthesiology interns underwent a 2-day training course in which they performed 9 central venous catheter placements, while attached to motion sensors on the dorsum of their dominant hand and ultrasound probe. MEASUREMENTS AND MAIN RESULTS: Motion metrics were analyzed using generalized estimating equations for both the overall procedure and predefined segments. Five attending anesthesiologists performed 3 trials each for comparison. Overall, there was a negative trend in path length, translational motions, rotational sum, and time (p < 0.001), with the exception of translational motions of the ultrasound probe. Interns reached within 1 standard deviation of the attending anesthesiologists by trials 7-to-8 for most metrics. Segmentation identified specific components of the procedure that were either significantly improved upon or required deliberate practice. The novel metric of rotational sum exhibited a moderate-to-strong positive correlation with other metrics (p < 0.001). CONCLUSIONS: A comprehensive series of motion metrics was able to describe the learning curves of novices training to perform central venous catheter placement in the simulation setting. Furthermore, it was determined that segmentation may provide additional insight into skill acquisition and inform deliberate practice.

Echocardiographic and Other Preprocedural Predictors of Heart Failure After TIPS Placement in Patients With Cirrhosis: A Single-Center 15-Year Analysis.

BACKGROUND. Heart failure (HF) is an uncommon complication after TIPS placement; its development represents a poor prognostic factor. OBJECTIVE. The purpose of our study was to evaluate the frequency, risk factors, and association with survival of HF developing within 90 days after TIPS placement in patients with cirrhosis. METHODS. This retrospective single-center study included patients with cirrhosis who underwent nonemergent covered-stent TIPS placement from June 2003 to December 2018 and who underwent echocardiography within 2 months before TIPS placement and had at least 90 days of post-TIPS follow-up. Development of HF within 90 days after TIPS was recorded. Frequency of TIPS reduction for post-TIPS HF was determined. Univariable logistic regression analysis and ROC curve analysis were performed to assess potential risk factors for post-TIPS HF. Association of post-TIPS HF and 1-year survival was assessed by the log rank test. RESULTS. The study sample included 107 patients (71 men and 36 women; median age, 58 years). Post-TIPS HF developed in 11 of 107 (10%) patients; median time to development of HF was 16 days (range, 2-62 days). Of these 11 patients, three (27%) required TIPS reduction to achieve resolution of HF symptoms after unsuccessful diuretic therapy. Pre-TIPS right atrium size (odds ratio [OR], 3.26 [95% CI, 1.22-10.16]; p = .03], left ventricle (LV) end-systolic dimension (OR, 5.43 [95% CI, 1.44-24.50], p = .02), LV end-diastolic dimension (OR, 4.12 [95% CI, 1.51-13.47]; p = .009), and estimated peak pulmonary artery systolic pressure (PASP) (OR, 1.27 [95% CI, 1.12-1.50]; p = .001) were associated with post-TIPS HF. AUC of right atrium size, LV end-systolic dimension, LV end-diastolic dimension, and estimated peak PASP for development of post-TIPS HF were 0.71, 0.74, 0.72, and 0.83, respectively. At a cutoff of 31 mm Hg, PASP achieved sensitivity of 70% and specificity of 86% for post-TIPS HF. Patients with post-TIPS HF and those without post-TIPS HF had 1-year survival of 46% versus 73% (p = .06). CONCLUSION. Multiple pre-TIPS echocardiographic variables predict the development of post-TIPS HF in patients with cirrhosis. CLINICAL IMPACT. Preprocedural echocardiography may guide risk stratification in patients with cirrhosis being considered for TIPS placement.
