RESUMO
BACKGROUND: Traditional management for right-sided infective endocarditis and other adherent masses centers around balancing the risks and benefits of open surgical removal against medical therapy. METHODS: Single-center study analysis of 19 patients who underwent vacuum-assisted debulking and/or en bloc removal of right-sided infective endocarditis and other adherent masses between September 2017 and November 2021. Clinical outcomes during the perioperative period, postoperative period, hospital course, and post-discharge were analyzed. RESULTS: We included 12 male and 7 female patients with an average age 47.4 ± 16.8. Relevant risk factors included 47.4% of patients with active intravenous drug use (IVDU), 21.1% of patients with a history of permanent pacemaker (PPM) or implantable cardioverter-defibrillator (ICD), and 5.3% of prior malignancy with mediastinal radiation. 31.6% of patients had documented right-sided masses from a non-infectious etiology, while 68.4% of patients were noted to have right-sided infective endocarditis (RSIE). All patients were found to have large, mobile masses or vegetations at high risk for embolization to the pulmonary vasculature. Average in-hospital length of stay was 17.8 ± 12.2 days, blood cultures cleared postoperatively in 8.9 ± 7.3 days, periprocedural mortality was 0%, subsequent open surgical valvular repair during the same admission was 5.3%, and in-hospital mortality was 5.3%. Within 6 weeks of follow-up, 15.8% of patients were readmitted for recurrence of bacteremia, 10.5% of patients were found to have new pulmonary embolism, and 15.8% of patients underwent open surgical valvular repair. Total death after 1-year and 2-years was 15.8% and 5.3%, respectively. Recurrence of bacteremia was 21.1% within 1-year. CONCLUSION: AngioVac is a viable therapeutic strategy for select patients with intravascular and intracardiac right-sided masses including thrombi, emboli, or infective masses such as endocarditis.

Previous reports comparing transcarotid (TC) versus transfemoral (TF) approaches for patients undergoing transcatheter aortic valve replacement have had inconsistent conclusions. We compared in-hospital and 1-year clinical outcomes, changes in quality of life, and direct hospital costs for 138 TC versus 1,926 TF procedures. Propensity matching based on the Society of Thoracic Surgery Predicted Risk of Mortality was used to compare 130 patients who underwent TC with 813 patients who underwent TF. Matched TC versus TF cohorts did not differ with respect to in-hospital mortality (0.0% vs 1.4%, p = 0.380), stroke (2.3% vs 2.5%, p = 0.917), major vascular complications (0.8% vs 2.2%, p = 0.268), composite bleeding complications (4.6% vs 6.4%, p = 0.647), requirement for permanent pacemaker (14.6% vs 12.9%, p = 0.426), postoperative hospital length of stay (3.3 ± 3.4 vs 3.1 ± 3.3 days, p = 0.467), or direct hospital costs ($52,899 ± 9,560 vs $50,464 ± 10,997, p = 0.230). Similarly, at 1-year, patients who underwent TC versus patients who underwent TF did not differ with respect to all-cause mortality (7.6% vs 6.4%, p = 0.659), hospital readmission (20.0% vs 23.9%, p = 0.635), or quality of life as measured by the Kansas City Cardiomyopathy Questionnaire score (84.0 ± 17.1 vs 88.4 ± 13.9, p = 0.062). Patients who underwent TC and TF did not differ with respect to in-hospital complications, length of hospital stay, and direct hospital costs, as well as 1-year mortality, readmission, and quality of life. These data add to ongoing support for the TC approach as the optimal alternative access for patients with transcatheter aortic valve replacement deferred from a transfemoral approach.

A 64-year-old patient presented with shortness of breath and chest pressure. The initial examination was unremarkable, and a chest X-ray revealed a large mediastinal mass. Computed tomography (CT) scan demonstrated a lobulated mediastinal mass involving the great vessels and mass effect on the trachea, esophagus, and heart. A CT-guided biopsy showed a monotonous, evenly spaced population of mature, normal-appearing adipocytes consistent with a well-differentiated lipoma-like liposarcoma/atypical lipomatous tumor. The patient underwent a median sternotomy with en bloc tumor resection without adjuvant chemoradiation. Three-year follow-up CT imaging shows no evidence of tumor recurrence.
RESUMO
OBJECTIVE: Transcarotid access for transcatheter aortic valve replacement is emerging as an alternative to more traditional nonfemoral access options such as transapical or transaortic; however, comparative data are limited. The purpose of the study was to analyze outcomes after transcatheter aortic valve replacement using transcatheter compared with transthoracic (transapical/transaortic) access. METHODS: The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry was queried for patients who underwent transcarotid, transapical, or transaortic transcatheter aortic valve replacement with the SAPIEN 3 (Edwards Lifesciences, Irvine, Calif) transcatheter heart valve between June 2015 and July 2019. Thirty-day unadjusted outcomes were evaluated, and propensity score matching and logistic regression were used to compare transcatheter access with transthoracic access. RESULTS: In the propensity-matched analysis, 667 transcarotid transcatheter aortic valve replacement procedures were compared with 1334 transthoracic procedures. Transcarotid transcatheter aortic valve replacement was associated with lower mortality (4.2% vs 7.7%, P = .004), less new-onset atrial fibrillation (2.2% vs 12.1%, P < .0001), fewer readmissions at 30 days (9.8% vs 16.1%, P = .0006), shorter median length of stay (3.0 vs 6.0 days, P < .0001), shorter median intensive care unit stay (25 vs 47.2 hours, P < .0001), and greater 30-day Kansas City Cardiomyopathy Questionnaire score improvement from baseline (25.1 vs 20.8, P = .007). Stroke (4.3% vs 3.7%, P = .44) and major vascular complications (1.4% vs 1.9%, P = .40) were similar. CONCLUSIONS: Transcatheter aortic valve replacement using transcarotid access is associated with lower 30-day mortality, less atrial fibrillation, shorter intensive care unit and overall length of stay, fewer readmissions, greater improvement in Kansas City Cardiomyopathy Questionnaire scores, and no significant difference in stroke or major vascular complications compared with transthoracic access.

Platypnea-Orthodeoxia syndrome (POS) is a rare clinical syndrome characterized by shortness of breath in the upright position that is relieved with supine positioning. We present a rare case of persistent left superior vena cava (PLSVC) draining into the left atrium causing a right-to-left shunt and subsequent POS. A 30-year-old female with a past medical history of hypertrophic cardiomyopathy, congenital Long QT syndrome and a left-sided dual chamber implantable cardioverter-defibrillator (ICD) presented with dyspnea and lightheadedness. Prior to presentation, the patient underwent a left-sided ICD extraction due to ICD lead infection and re-implantation from the right side through the cephalic vein. After further investigation, it was concluded that the PLSVC resulted in a physiological right-to-left shunting causing POS, with resolution of her symptoms after surgical ligation. To our knowledge, this is the first case report of PLSVC presenting with POS without anatomical intracardiac shunts following iatrogenic right superior vena cava (RSVC) obstruction.

BACKGROUND: Subclavian/axillary (TAx) access has become the most frequently used alternative access route for transcatheter aortic valve replacement (TAVR). Transcarotid (TC) TAVR has grown in popularity recently. Comparative data between these 2 contemporary access methods is lacking. METHODS: Data were extracted from The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy (TVT) Registry™ (June 2015 to October 2019) for patients undergoing TAVR by TC or TAx access with the SAPIEN 3 and SAPIEN 3 Ultra (Edwards Lifesciences, Irvine, CA) transcatheter heart valves. Procedural, index hospitalization, and 30-day outcomes were analyzed for TC vs TAx groups after 1:2 propensity matching of patient baseline characteristics. RESULTS: The study included 3903 cases, of which 801 TC and 3102 TAx procedures were compared. After 1:2 propensity matching, TC TAVR was associated with similar 30-day mortality (4.3% vs 5.2%, P = .34) but a significantly lower risk of stroke (4.2% vs 7.4%; hazard ratio, 0.56; 95% confidence interval, 0.38-0.83; P = .003) compared with TAx access. Other outcomes that favored TC over TAx included shorter procedure time (117.0 vs 132.4 minutes; P < .001) and fluoroscopy time (16.6 vs 21.6 min; P < .001), lower contrast volume (78.5 vs 96.7 mL; P < .001), shorter length of stay in the intensive care unit (24.3 vs 25.0 hours; P = .02) and hospital (2.0 vs 3.0 days; P = .002), and more patients discharged to home (82.9% vs 74.6%; P < .001). CONCLUSIONS: TC TAVR is associated with similar mortality and a significant reduction in stroke compared with the TAx approach. If femoral access is precluded, TC may be a safe, or at times, preferred avenue of transcatheter valve delivery.

BACKGROUND: Previous reports described successful use of transcarotid and transsubclavian approaches for the performance of transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis who cannot be treated with transfemoral access. The purpose of the present study was to compare these two alternative approaches with respect to safety, efficacy, and procedural efficiency. METHODS: A retrospective analysis of all TAVR procedures performed through either a transcarotid or a transsubclavian approach at a single tertiary care medical center between January 2016 and October 2018 was performed. Outcomes are reported in accordance with the Valve Academic Research Consortium definitions. RESULTS: During the study period, 33 patients had transcarotid TAVR and 38 patients had transsubclavian TAVR. Transcarotid patients were older (mean age, 82.9 ± 7.2 vs 78.1 ± 8.2 years; P = .012), but otherwise the two groups were not significantly different with respect to preoperative characteristics. Valve deployment was similar between the groups (100% vs 97%; P = .348). Procedure time was shorter with the transcarotid approach (110 ± 32 vs 134 ± 45 minutes; P = .014). There was a lower mean fluoroscopy air kerma in the transcarotid group (682.82 ± 713.48 mGy vs 2141 ± 2055 mGy; P < .001), although fluoroscopy dose-area product did not differ between the groups. There was no difference between the groups with respect to in-hospital or 30-day mortality (0% vs 3%; P = .355), stroke (3% vs 8%; P = .393), or vascular complication (3% vs 4%; P = .840). CONCLUSIONS: The transcarotid and the transsubclavian approaches have similar safety and efficacy outcomes. The transcarotid approach had a shorter procedure duration and a trend toward lower fluoroscopy duration and radiation exposure.

Periprocedural stroke related to transcatheter aortic valve replacement (TAVR) is associated with increased morbidity and mortality. Cerebral embolic protection using the Sentinel device (Claret Medical) has demonstrated reduced rates of stroke during TAVR. However, alternative access such as a transcarotid approach precludes the use of the Sentinel device. We report a case using cerebral embolic protection during a right transcarotid TAVR.

BACKGROUND: Surgical treatment of extensive tracheal lesions remains a major challenge because of lack of an ideal airway substitute that is well vascularized, rigid, and autologous. We describe a novel surgical technique of tracheal reconstruction using a combination of a polypropylene mesh material and anterior cervical myocutaneous flap in a dog model. MATERIALS AND METHODS: A 3.5-4 cm length of cervical trachea was resected in 16 dogs and replaced with a myocutaneous cervical neck flap wrapped around the plain polypropylene tube (group 1, n = 7) or wrapped around a composite of polypropylene tube with an implanted Z-type metallic-covered stent (group 2, n = 9). The cervical tracheal defect was repaired with the previously mentioned substitute that was directly sutured to the remaining tracheal ends. Dogs were followed up using bronchoscopy and x-rays and euthanized at predetermined times for histologic examination. RESULTS: In group 1, four dogs died within 2 wk from respiratory failure with varying degrees of airway collapse and difficulties in expectoration. In group 2, eight dogs survived, whereas one died of anastomotic dehiscence 1 wk after surgery. Necropsy and histologic examination of the anastomotic sites revealed good healing tissue. Pathologic examination also revealed excellent healing of the squamous epithelium of the neotrachea and the columnar epithelium of the native tracheal mucosa. CONCLUSIONS: The tissue compatibility of the polypropylene mesh material and anterior cervical myocutaneous skin flap makes this a promising therapeutic substitute for treatment of patients with extensive tracheal lesions.

Carotid angioplasty requires early placement of a cerebral protection device in an effort to minimize cerebral embolization during the conduct of the subsequent angioplasty and stenting procedure. In patients who exhibit a very critical internal carotid artery (ICA) stenosis (approximately 99%), initial passage of the lesion may not be possible with a standard 0.014-inch wire system. In this report, the authors describe an approach using a 0.012-inch hydrophilic system to overcome this technical obstacle.

PURPOSE: Patients after infrainguinal vein bypasses are a group at risk of graft stenosis and occlusion. Revision of failing grafts has been shown to significantly improve bypass patency and limb salvage. Options for surgical revision of mid bypass stenosis includes either patch angioplasty (PA) or interposition grafting (IG). We reviewed our experience with surgical revision of vein bypass stenosis. METHODS: From April 1968 to March 2006, 7557 autogenous vein bypasses were performed at Albany Medical Center and its affiliated institutions, of these 316 required single or multiple revision of vein grafts with patch angioplasty or interposition vein grafting. Excluded were proximal and distal anastomotic revisions. Only 235 bypasses had single revisions as either patch angioplasty (n = 108) or interposition grafting (n = 127) and are the focus of this review. The initial bypass revisions in these two groups are analyzed for indications, clinical parameters, operative strategies, and long-term patencies and clinical outcomes. RESULTS: There were no significant differences in mean age, gender, or frequency of comorbid conditions (coronary artery disease, pulmonary disease, hypertension, and diabetes) between the two patient groups. Secondary patency of patch angioplasty revision at 5 years was 79%. Patencies for interposition grafting revision at 5 years were equivalent to patch angioplasty group at 75%. When bypasses were evaluated on the basis of initial reconstructions (ie, in situ vs excised vein bypass), the results showed that in situ bypasses that required initial revision had similar 5-year patencies when interposition grafting was used as the first revision strategy vs patch angioplasty (80% vs 73%). Excised vein bypasses had similar patency when patch was their first revision strategy vs interposition grafting (4 year secondary patency 92% vs 75% respectively). CONCLUSION: Autogenous vein bypasses are at risk for developing significant stenosis and occlusion with time. Bypass stenosis that develops in the main body of the graft can be effectively repaired using either patch angioplasty or interposition grafting. Depending on the host of other factors, such as availability of autogenous venous conduit, location of stenosis, accessibility for operative repair, and the patient's anatomic characteristics, either operative strategy is effective in prolonging the patency of the bypass.
