We herein describe a surgical case of pulmonary involvement in Takayasu's arteritis with pulmonary infections of nontuberculous mycobacteria. A 24-year-old female was admitted to our hospital because of a recurrent fever, and contrast-enhanced computed tomography of the chest revealed the occlusion of the right pulmonary artery and cavitary lesions in the right lower lobe of the lung. A further examination of the neck revealed the occlusion of aortic branches, and the patient was diagnosed with Takayasu's arteritis...

BACKGROUND: We have reported "sandwich technique," via a right ventricular incision, to treat a post-infarction ventricular septal defect (VSD). This technique involves the placement of patches on both the left and right sides of the septum, pinching the VSD sealed with surgical adhesive between the two patches. In this study, we analyzed factors influencing 1-year mortality to determine the pitfalls in our procedure. METHODS: We evaluated 24 consecutive patients with post-infarction VSD who underwent the "sandwich technique" via a right ventricular incision...

Anatomical variations of the pulmonary artery increase the risks for vessel injury and critical mistakes during pulmonary artery resection. The mediastinal basal pulmonary artery is a rare branch abnormality and is the first branch of the pulmonary artery to flow into the basal segment. We report a patient who underwent video-assisted thoracic surgery (VATS) right lower lobectomy for lung cancer with a mediastinal basal pulmonary artery. The mediastinal basal pulmonary artery was detected preoperatively by computed tomography...

BACKGROUND: We sought to quantify the effect of severe postoperative bleeding in hemodynamically stable patients following cardiac surgery. METHODS: We reviewed the charts of all cardiac surgery patients operated on at our institution between 2010 and 2014. After excluding patients with tamponade or MAP <60, we propensity matched patients having chest tube output >300 mL in the first postoperative hour, >200 mL in the second, and >100 mL in the third ("bleeding" group) with patients having <50 mL/h of chest tube output ("dry" group)...

The rates of mortality and morbidity remain high in surgery for acute type A dissection. There is controversy regarding the best cannulation strategy for achieving good clinical results. Each cannulation technique has different anatomical characteristics and a different flow pattern inside the aorta during cardiopulmonary bypass. Some adverse, clinically important outcomes may be related to events at this time. Femoral artery cannulation, axillary artery cannulation, and central aortic cannulation are the three major cannulation strategies that are adopted in many centers in the world...

Leiomyoma of the mediastinum is rare. They are thought to arise from the smooth muscle cells of the media of mediastinal vascular structures and structure containing smooth muscle. Most mediastinal leiomyomas are seen in association with oesophagus in the posterior mediastinum. We present a case of huge leiomyoma in a 1.5 years old male child arising in the lower anterior mediastinum with compression of heart, liver and deformity of rib cage. Median sternotomy and a separate concomitant right mini-thoracotomy was done and tumor excised...

Since its introduction in the mid-1990s, minimally invasive mitral valve surgery (MIMVS) has been shown to be a feasible alternative to a conventional full-sternotomy approach, and several studies have reported excellent clinical outcomes with low perioperative morbidity and mortality. As a result, MIMVS is being increasingly employed as a routine procedure worldwide. On the other hand, several issues have been raised, including complications specific to this technique and its steep learning curve, while there are also concerns regarding the durability of a mitral valve repair through a limited access...

An 84-year-old woman was referred to our hospital with a suspected cardiac tumor detected by transthoracic echocardiography performed as a preoperative examination of gastric cancer. In addition to a tumor in the left atrium, we found on cardiac ultrasound a 15-mm mobile tumor that adhered to the aortic valve. Gross findings and histological examination confirmed that the tumor in the left atrium was a cardiac myxoma, and that the tumor adhered to the aortic valve was a papillary fibroelastoma. We experienced a rare case where preoperative examination before gastrectomy accidentally revealed concomitant cardiac tumors...

OBJECTIVES: Atrial natriuretic peptide is a cardiac atrium-derived hormone and its cardioprotective effects have recently been confirmed, but the actual mechanism underlying these effects has not been well elucidated. In this study, we proposed that atrial natriuretic peptide achieves its effects in part via peroxisome proliferator activated receptor γ, a nuclear receptor. METHODS: Hemodynamic data in swine heart ischemia-reperfusion model were measured under the conditions of no medication for control (Group N, n = 8) or that of carperitide (synthetic human atrial natriuretic peptide) systemic administration (Group A, n = 8)...

Hypothermic circulatory arrest is a critical component of aortic arch procedures, without which these operations could not be safely performed. Despite the use of hypothermia as a protective adjunct for organ preservation, aortic arch surgery remains complex and is associated with numerous complications despite years of surgical advancement. Deep hypothermic circulatory arrest affords the surgeon a safe period of time to perform the arch reconstruction, but this interruption of perfusion comes at a high clinical cost: stroke, paraplegia, and organ dysfunction are all potential-associated complications...

OBJECTIVE: Chronic totally occluded right coronary artery (CTO-RCA) often poses a problem in decision making for/against bypass grafting due to the lack of standardized indication criteria. The aim of the study was to investigate whether qualitative angiograms can be useful in decision making for/against surgical revascularization of CTO-RCA. METHODS: A retrospective cohort study was conducted with 69 patients who underwent elective CABG procedure, including single graft to the RCA...

Transcatheter closure of paravalvular leaks requires precise assessment of the location, size, and shape of the defect. Transesophageal echocardiography plays an important role in this process. We encountered a case of a paravalvular leak at the aortic position after aortic and mitral valve replacement. It was impossible to detect the precise location of the paravalvular leak with transesophageal echocardiography because of an acoustic shadow from the mitral mechanical valve. Intraoperative use of intravascular ultrasound was useful for determining the morphology of the defect and evaluating the procedure during the operation...

OBJECTIVE: We sought to compare the outcomes of Carpentier-Edwards PERIMOUNT (CEP), Magna and Magna Ease valves in Japanese elderly patients with severe aortic valve stenosis (AS). METHODS: We retrospectively identified 136 patients (mean age 76.61 ± 5.5 years old) who had undergone isolated surgical aortic valve replacement (SAVR) using CEP, Magna, and Magna Ease valves at a single institution, from January 2001 to December 2013. We compared the valves according to their survival rates, freedom from major adverse cardiovascular and cerebrovascular events (MACCE), and durability and hemodynamic performance by echocardiographic data...
