RESUMO
BACKGROUND: Endovascular treatment (EVT) for aortoiliac (AI) occlusive lesions is now conducted worldwide, but there are challenges in EVT for complex AI lesions. The VIABAHN VBX (W.L. Gore & Associates, Flagstaff, AZ) is a next-generation balloon-expandable covered stent designed for use with complex AI lesions. The purpose of this study is to evaluate the medium-term outcomes of VIABAHN VBX for such lesions. METHODS: Symptomatic patients who underwent EVT with VIABAHN VBX for an AI lesion from 2018 to 2020 at 7 Japanese centers were reviewed retrospectively. The primary endpoints were primary patency and freedom from target lesion revascularization (TLR). RESULTS: A total of 95 EVT procedures with VIABAHN VBX for AI occlusive lesions were performed in 71 patients. The patients had high rates of dyslipidemia (53%) and chronic kidney disease (61%), and 22% had chronic limb-threatening ischemia (CLTI). The Transatlantic Inter-Society Consensus (TASC â ¡) class was A in 12 patients (17%), B in 12 (17%), C in 10 (14%), and D in 37 (52%). Severe calcification (360°) of the treated lesion was present in 31 patients (33%). The median procedure time was 84 (49-158) min, with a technical success rate of 100%. The median follow-up period was 36 (32-43) months. The 3-year primary and secondary patency of VIABAHN VBX were 91% and 99%, the 3-year freedom from TLR was 92%, and the 3-year freedom from major adverse limb event (MALE) was 98%. No limbs required major amputation. Lesion severity (TASC â ¡ C or D) and severe calcification did not affect the primary patency or freedom from TLR. CONCLUSIONS: Medium-term outcomes after EVT with VIABAHN VBX for AI lesions were acceptable regardless of lesion severity and calcification. These results suggest that VIABAHN VBX may be suitable for AI occlusive lesions with severe anatomical complexity and/or severe calcification.

BACKGROUND: The purpose of the study is to evaluate the efficacy of thromboendarterectomy (TEA) for common femoral occlusive disease using bovine pericardium patch angioplasty. METHODS: The subjects were patients who underwent TEA for common femoral occlusive disease with bovine pericardium patch angioplasty from October 2020 to August 2021. The study had a prospective, multicenter, and observational design. The primary end point was primary patency (freedom from restenosis). The secondary end points were secondary patency, amputation-free survival (AFS), postoperative wound complication, hospital death within 30 days, and major adverse cardiovascular events (MACE) within 30 days. RESULTS: Forty-seven TEA procedures with a bovine patch were performed in 42 patients (34 males; median age, 78 years; diabetes mellitus, 57%; end-stage renal disease with hemodialysis, 19%). Clinical presentations were intermittent claudication (68%) and critical limb-threatening ischemia (32%). Sixteen (34%) limbs underwent TEA alone and 31 (66%) underwent a combined procedure. Surgical site infection (SSI) occurred in 4 limbs (9%) and lymphatic fistulas in 3 limbs (6%). One limb with SSI required surgical debridement 19 days after the procedure, and 1 limb (2%) without postoperative wound complications required additional treatment due to acute bleeding. Hospital death within 30 days occurred in 1 case due to panperitonitis. There was no MACE within 30 days. Claudication was improved in all cases. Postoperative ABI of 0.92 [0.72-1.00] was significantly higher than the preoperative value (P < 0.001). The median follow-up period was 10 months [9-13 months]. One limb (2%) required additional endovascular therapy due to stenosis at the endarterectomy site at 5 months postoperatively. Primary and secondary patencies were 98% and 100% at 12 months, respectively, and the AFS rate was 90% at 12 months. CONCLUSIONS: Common femoral TEA with bovine pericardium patch angioplasty has satisfactory clinical outcomes.

A 45-year-old man complaining of chest and back pain due to acute aortic dissection was referred to our department. A contrast enhanced computed tomography( CT) scan showed Stanford type B aortic dissection with Kommerell diverticulum and aberrant right subclavian artery. The patient underwent antihypertensive treatment for one month. Despite the successful treatment, CT scan revealed a 5 mm false lumen dilatation in this period. We decided to close the primary entry. The operation was performed through median sternotomy;after establishing cardio-pulmonary bypass, the ostium of the aberrant right subclavian artery( ARSA) was sutured closed and anastomosed the ARSA and right common carotid artery. Total arch replacement was performed using frozen elephant trunk technique. His postoperative course was uneventful.

We treated an 80-year-old Japanese woman who had Takotsubo syndrome (TTS) concomitant with a left atrial (LA) tumor. Left ventriculography revealed a variant of TTS. In cardiac surgery, the LA mass was successfully resected without embolism, with the pathological diagnosis of myxoma.
RESUMO
An 83-year-old woman with congestive heart failure due to severe mitral regurgitation was referred to our department. Because acute coronary syndrome was suspected, the patient underwent emergent coronary artery angiography, which showed 75% stenosis of segment 2 and 90% stenosis of segment 11. Subsequently, segment 11 was treated by percutaneous coronary intervention. Additionally, transesophageal echocardiography findings showed a prolapse of P2 due to papillary muscle rupture. After management of heart failure, a scheduled operation was performed under the diagnosis of acute mitral regurgitation due to papillary muscle rupture. Intraoperative findings demonstrated a rupture of the anterior papillary muscle, prolapse of P2, and no evidence of infection. The patient underwent mitral valve repair with artificial chordae through median sternotomy. Her postoperative course was uneventful.

OBJECTIVE: Silent brain lesions are known to occur after coronary artery bypass grafting (CABG). The aim of this study was to seek the incidence rate, the influence of procedures, and their impact on the postoperative course. METHODS: From July 2016 to April 2018, 104 consecutive patients undergoing elective and isolated first-time CABG (65 off-pump and 39 on-pump) were enrolled. New brain lesions were evaluated by brain magnetic resonance imaging both before and after CABG. Postoperative outcomes, including cognitive function, were compared between patients with and without brain lesions. RESULTS: The overall incidence of new brain lesions was 20.1% (21/104). Excluding one symptomatic stroke case, silent brain lesions were revealed in the remaining patients. The percentage of on-pump CABG (61.9% [13/21] vs 31.3% [26/83], P = .019) and aortic clamp (52.4% [11/21] vs 24.1% [20/83], P = .014) were significantly greater in patients with brain lesions. Brain lesions were observed in 12.3% and 15.8% of patients in the off-pump and anaortic CABG. The Katz Index of Independence in Activities of Daily Living was significantly lower in patients with brain lesions (from 5.8 ± 0.9 to 5.4 ± 1.2 vs from 5.9 ± 0.5 to 5.9 ± 0.6, P = .013). In patients with new lesions, postoperative cognitive dysfunction (POCD) was observed only in multiple lesions, and the maximum size was significantly greater in patients with POCD. CONCLUSIONS: Magnetic resonance imaging of the brain frequently detected postoperative silent brain lesions after CABG in off-pump and aorta non-touch groups. Multiple and larger new brain lesions were associated with the development of POCD.

An 81-year-old man who had undergone aortic valve replacement was transferred to our hospital due to suspected prosthetic valve endocarditis(PVE) from the regional hospital. Transesophageal echocardiography findings showed severe aortic regurgitation with mobile vegetation on the right coronary cusp and annular abscess corresponding to left-none coronary cusps. Urgent operation was performed under the diagnosis of PVE with aortic root abscess. Intraoperative findings demonstrated tiny vegetation on one of the bio-prosthetic leaflets and abscess formation beneath the left sinus of valsalva( LSOV). Complete debridement of the infected tissue followed by patch closure of the cavity below the LSOV and reconstruction of the aortic root with Freestyle stentless aortic bioprosthesis was performed. His postoperative course was uneventful. Aortic root replacement using a stentless bioprosthesis seems to represent one of the useful options for PVE with aortic root abscess.

A 59-year-old female patient who was diagnosed with giant right atrial appendage aneurysm (75 × 87 mm) underwent minimally invasive repair via right mini-thoracotomy. The aneurysm was completely excluded by linear method under beating heart without cardiac arrest. The postoperative recovery was uneventful and she was discharged home without symptoms 16 days after surgery.
