Abstract OBJECTIVES The actual underlying mechanisms of acute type A aortic dissection (AAAD) are not well understood. present study aimed to elucidate the mechanism AAAD using computational fluid dynamics (CFD) analysis. METHODS We performed CFD analysis patient-specific computed tomography imaging in 3 healthy control cases and patients with AAAD. From images, we made a model or pre-dissection for Pulsatile cardiac flow during one cycle was simulated, three-dimensional streamline...
This study aimed to evaluate the prevalence of spinal cord injury in total arch replacement with frozen elephant trunk for acute type A aortic dissection using our protection technique.Between January 2013 and December 2017, 33 patients underwent (mean age 67.9 ± 13.3 years). Our technique involved maintaining extracorporeal circulation through left subclavian artery all procedures, occlusion balloon during distal anastomosis, inserting above Th 8 transesophageal echocardiographic guidance....
Abstract OBJECTIVES The management of aortic arch disease is complex. Open surgical continues to evolve, and the introduction endovascular repair revolutionizing surgery. Although these innovative techniques have generated opportunity for better outcomes in select patients, they also introduced confusion uncertainty regarding best practices. METHODS In New York, we developed a collaborative group, York Aortic Consortium, as means cross-linking knowledge working together understand treat...
It is difficult to estimate the improvement in left ventricular (LV) function after aortic valve replacement (AVR). The present study aimed evaluate whether energy loss (EL) can predict postoperative LV AVR.Nine patients who underwent AVR with a bioprosthetic were enrolled study. Porcine prostheses used 5 and bovine pericardial 4 patients. flow pattern was visualized EL cardiac output (CO) measured using 4-dimensional magnetic resonance imaging from descending aorta; EL/CO ratio extracted...
Abstract A 38-year-old woman presented with exertional dyspnea and chest compression. She had undergone repair of congenital supravalvular aortic stenosis at 8 years age. Contrast-enhanced computed tomography showed re-stenosis in the ascending aorta, bilateral coronary arterial aneurysm, a highly thickened left ventricular wall. Release was necessary to avoid functional deterioration; however, it could cause demand–supply mismatch flow due substantial hypertrophy. Sufficient statistical...
The timing and choice of surgical method for type B aortic dissection, is still a topic much debate. We performed total arch replacement using frozen elephant trunk (TAR-FET) as means preventing distant events, such retrograde A dissection (RTAD). conducted analysis 142 patients with acute who were admitted between January 2010 July 2017. Fifty-five cases required intervention to treat enlargement the false lumen diameter ULP formation 2 weeks after onset symptoms. 17 TAR-FET mean 42±26 days...
Abstract OBJECTIVES The aim of this study was to elucidate the remodelling internal mammary artery (IMA)–left anterior descending anastomosis and compare 2 different techniques (end-to-side versus side-to-side) using computational fluid dynamics. METHODS This included 9 patients. Computed tomography (CT) angiography performed immediately after coronary bypass grafting (CABG) at 3–6 months later. dynamics models were made CT data. pulsatile 3-dimensional blood flow achieved with finite volume...
Coronary artery bypass grafting (CABG) has been reported for coronary diseases in patients with Kawasaki disease and complications after arterial switch operations transposition of the great arteries. However, only a few studies have explored this modality congenital anomalies. As anomalies, particularly left atresia stenosis, are one reasons sudden death, revascularization is often required infants young children. Therefore, we aimed to investigate outcome CABG such anomalies
Objectives Veno-arterial extracorporeal life support (V-A ECLS) is increasingly being utilized for postcardiotomy shock (PCS), though data describing the relationship between type of indexed operation and outcomes are limited. This study compared V-A ECLS across four major cardiovascular surgical procedures. Methods was a single-center retrospective patients who required PCS 2015 2022. Patients were stratified by operation, which included aortic surgery (AoS), coronary artery bypass grafting...
This study investigates the impact of bilateral antegrade cerebral perfusion time on outcomes in aortic arch surgery.
Abstract OBJECTIVES Late complications of arterial switch operations (ASO) for transposition the great arteries, such as neo-pulmonary artery (PA) stenosis and/or neoaortic regurgitation, have been reported. We developed an alternative reconstruction method called longitudinal extension (LE) to prevent PA bifurcation (PABS). METHODS identified 48 patients diagnosed with arteries and performed ASO using Lecompte manoeuvre neo-PA reconstruction. In 9 consecutive (from 2014), LE was (LE)....
Damage to the posterior wall of left ventricle (LV) can cause tethering mitral regurgitation (MR). We present a patient with non-ischaemic MR and congestive heart failure due cardiac sarcoidosis who was treated using an endocardial linear infarct exclusion technique.A 63-year-old woman history uveitis presented our hospital complaining dyspnoea. Echocardiography revealed dyskinesis posterolateral LV severe (regurgitation volume: 92 mL). The ejection fraction reduced 45%. Cardiac...
B型大動脈解離に対してエントリー閉鎖の有用性が証明され，TEVARが施行されている。中枢ランディングに問題のある症例には遠隔期の大動脈イベントを発症するリスクがある。フローズンエレファントトランクを用いた全弓部置換（TAR-FET）を遠位弓部にエントリーが存在する17例に施行。対麻痺等の合併症なく大動脈イベント回避率は5年で90%，35%の偽腔縮小率で良好なリモデリングを得た。TAR-FETは安全なB型解離の治療戦略の一つと考える。
