Abstract A calcified amorphous tumor (CAT) of the heart is a rare, non-neoplastic, intracavitary cardiac mass. Histological examination reveals presence and fibrous material with underlying chronic inflammation. Some studies have reported that CAT typically exhibits rapid growth. However, we observed case in which unexpectedly ruptured within approximately two weeks. There was no cerebral infarction or significant valvular disease, therefore were not sure about indication for surgery;...

Abstract Herein, we report a case of transapical transcatheter aortic valve replacement and coronary artery bypass grafting performed in an on-pump beating fashion old woman with severe stenosis, porcelain aorta, calcified disease, history abdominal replacement.

Coronary artery fistulas (CAFs) are rare coronary anomalies. Among these, artery-pulmonary can lead to myocardial ischemia through mechanisms such as steal, stenosis, and vasospasm. We report a case of 73-year-old male presenting with fistula 75% stenosis the right artery. Despite negative findings for on scintigraphy absence ST changes resting electrocardiogram (ECG), steal syndrome was suspected following an exercise ECG that revealed diffuse depression. Surgical intervention close...

Neuron-specific enolase (NSE) is one of the biomarkers used as an indicator brain disorder, but since it also found in blood cell components, there a concern that spurious increase NSE may occur after cardiovascular surgery, where cardiopulmonary bypass (CPB) causes hemolysis. In present study, we investigated relationship between degree hemolysis and surgery usefulness immediate postoperative values diagnosis disorder. A retrospective study 198 patients who underwent with CPB period from...

The low patency of synthetic vascular grafts hinders their practical applicability. Polyvinyl alcohol (PVA) is a non-toxic, highly hydrophilic polymer; thus, we created PVA-coated polycaprolactone (PCL) nanofiber graft (PVA-PCL graft). In this study, examine whether PVA could improve the hydrophilicity PCL and evaluate its in vivo performance using rat aorta implantation model. A with an inner diameter 1 mm electrospinning (control). nanofibers are coated PVA, resulting PVA-PCL graft....

Abstract Background This study explored if long-distance transfer was safe for patients suffering from acute aortic dissection type A (AADA) and also analyzed the effectiveness of helicopter cloud-type imaging systems such in northern Hokkaido, Japan. Methods Results The included 112 consecutive who underwent emergency surgical treatment AADA April 2014 to September 2020. were divided into two groups according location referral source hospitals: Asahikawa city group (group A, n = 49)...

The leukemoid reaction (LR) is reported to be caused by severe stress conditions such as infection, malignancies, intoxication, hemorrhage, or acute hemolysis; this condition attributed a very prognosis. Some reports have suggested that the LR was associated with systemic response. A 36-year-old man who required mechanical circulatory support (MCS), including veno-arterial extracorporeal membrane oxygenation and Impella 5.5 due heart failure, transferred our hospital. He showed markedly...

Abstract Nonbacterial thrombotic endocarditis (NBTE) on the aortic valve involves fibrin and platelet aggregate formation, potentially leading to embolic events. We present a case of NBTE following coronary angiography (CAG) in 54-year-old man with multiple comorbidities. Surgical thrombectomy was performed owing acute cerebral infarcts. This highlights significance considering that mechanical trauma from catheterization during CAG can trigger thrombus formation.

Abstract This case report details the management of a 79-year-old man who developed massive postoperative pneumothorax following redo coronary artery bypass grafting due to severe lung adhesions. We successfully treated patient using veno-venous extracorporeal membrane oxygenation without femoral cannulation, allowing for early rehabilitation initiation. Veno-venous is reasonable option cases respiratory failure with destruction caused by re-sternotomy during re-do cardiac surgery.

, often referred to as nutritionally variant streptococci, is generally a benign part of human microflora, primarily found in the oral cavity, digestive tract, and genitourinary system. However, it can have significant role infectious endocarditis (IE). We discuss case involving 53-year-old male who displayed serious signs indicative IE. The individual, had history IgA nephropathy, underwent successful surgical antibiotic intervention. Given challenge treating

Abstract Isolated left vertebral artery (ILVA) is one of the most frequent abnormalities. When performing thoracic endovascular aortic repair (TEVAR), ILVA may have to be closed depending on position stent graft; in these cases, decision reconstruct depends state cerebral blood flow. Here, we report a case 68-year-old male, whom Willis arterial circle was incomplete; therefore performed reconstructive method during zone 2-landing TEVAR that ensured and subclavian flow without use artificial...

A 78-year-old man underwent pericardial patch repair for left ventricular (LV) rupture during mitral valve replacement. After the first operation, a huge (>10 cm) LV pseudoaneurysm was detected, necessitating reoperation. is rare but often fatal complication of Although replacement has been reported, development after such exceedingly rare. In this case, we successfully treated using two patches to sandwich hole from inside.

Redo coronary artery bypass grafting after an in-situ right internal thoracic graft to the left anterior descending is challenging. For such a 52-year-old male patient with history of mediastinitis, we performed redo using saphenous vein and xiphoid resection via suprasternal route axillary as inflow source were patent. The for patients inaccessible aorta. Combining provides bail-out option.

Superior mesenteric artery (SMA) aneurysms (SMAAs) are rare and account for approximately 7% of all visceral aneurysms. If the anatomical complexity permits patency organ perfusion is allowed, then an endovascular approach first choice minimally invasive procedures. We report case a 92-year-old female with giant SMAA challenging anatomy, including short proximal sealing zone from origin SMA distal hepatic bifurcation. In view her advanced age, she was treated endovascularly covered stents....

The proper surgical strategy for retrograde type A aortic dissection (RTAD) is still controversial, and some studies have reported the efficacy of frozen elephant trunk thoracic endovascular repair (TEVAR). 68-year-old man was diagnosed with acute using enhanced computed tomography. false lumen at arch ascending aorta thrombosed, primary entry placed in descending aorta. In addition, there were malperfusions right renal artery both iliac arteries. We performed TEVAR femoral combined...

Vascular tissue engineering has shown promising results in "healthy" animal models. However, studies on the efficacy of artificial grafts under "pathological conditions" are limited. Therefore, this study, we aimed to characterize performance polyvinyl alcohol (PVA)-coated poly-ε-caprolactone (PCL) (PVA-PCL grafts) diabetic conditions. To end, PCL were produced via electrospinning and coated with hydrophilic PVA polymer, while a rat model (DM) was established streptozotocin injection....

This study aimed to investigate the effectiveness modified turn-up technique in AADA and compare this with other techniques.We divided 57 patients who underwent ascending aorta replacement into group (group A: 36 patients) B: 21 patients). Intraoperative postoperative course data were compared between groups B. In A, we also early-career surgeons (practicing <10 years after...

Abstract If multiple treatments are performed within a short time, when something occurs, it is difficult to identify its cause. Here, we present case of thoracic endovascular aortic repair (TEVAR) for acute dissection (AAD) after treatments. A 76-year-old woman underwent minimally invasive valve replacement, transcatheter lumbar artery embolism and retroperitoneal tumor resection period time. After series procedures, the patient experienced sudden back pain, computed tomography revealed an...

During stent grafting, managing the internal iliac artery (IIA) becomes a significant issue when an abdominal aortic aneurysm (AAA) is complicated by bilateral common (CIA) aneurysms. The branch system (IBS) has defined length; therefore, CIA should be sufficiently long. However, situations arise where IBS must used even in patients with short CIA. A case of contralateral occlusion due to deviation proximal branched component reported.A 73 year old man underwent grafting inferior mesenteric...

For patients with cardiogenic shock, delaying surgery mechanical circulatory support is reported to yield better outcomes than emergency surgery. We report on an 82-year-old man diagnosed vertebral osteomyelitis concomitant infective endocarditis. Chest radiographs revealed a growing abscess, which resulted in aorto-right ventricular fistula. Providing Impella allowed for hemodynamic stabilization prior The patient had uneventful postoperative course and be well follow-up 1 year later. can...

Cases that are inoperable owing to poor preoperative conditions sometimes encountered. However, there some cases led radical treatment by performing bridge therapy. Here, we presented a case of patient with complex cardiac disease in an state who underwent bridging therapy successful surgical treatment. A 73-year-old male received hemodialysis and had severe aortic valve stenosis coronary artery planned he was deemed his low function hemodynamic instability. Therefore, escape from fatal...
