Multiple percutaneous coronary interventions may negatively impact cardiac remodelling after bypass surgery.

Objectives: Many patients undergo percutaneous coronary intervention (PCI) multiple times before being referred for coronary artery bypass grafting (CABG), in which bypass grafts are often anastomosed to small distal targets with higher risk of graft failure. We aimed to assess whether multiple PCIs adversely affect the long-term outcomes of patients who undergo CABG subsequently.

Methods: A cohort of 368 patients with no history of PCI underwent initial isolated CABG between 2003 and 2013 (no PCI group).

[Surgical Treatment for Primary Pulmonary Artery Sarcoma;Report of a Case].

Primary pulmonary artery sarcoma is a very rare tumor. The prognosis of primary pulmonary artery sarcoma is extremely poor and it is reported as 1.5 months without treatment.

Comparison of clinical outcomes after coronary artery bypass grafting using stratified SYNTAX scores.

Objectives: Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are common procedures for managing coronary artery disease (CAD); however, optimal methods of comparing post-procedure outcomes are unclear. We evaluated the reliability of Synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) scores and investigated differences in long-term outcomes after CABG among groups with different SYNTAX scores.

Methods: According to patient selection criteria used in the SYNTAX trial, 368 patients who underwent isolated initial CABG between 2003 and 2014 at Kurashiki Central Hospital were stratified into three SYNTAX score I groups (low: < 23, intermediate: 23 to < 33, and high: ≥ 33) and three SYNTAX score II groups (low: < 30, intermediate: 30 to < 40, and high: ≥ 40).

[Occurrence of New Entry after Thoracic Endovascular Aortic Repair for Retrograde Stanford Type A Aortic Dissection;Report of Two Cases].

We report 2 cases of occurrence of new entry after thoracic endovascular aortic repair(TEVAR) for retrograde Stanford type A aortic dissection. Preoperative chest computed tomography (CT) demonstrated retrograde Stanford type A acute aortic dissection, and TEVAR was performed for entry closure. In the postoperative period, the aortic diameter was not dilated in either case and the false lumen of the ascending aorta disappeared in the case 2.

Technique to treat extensive abscesses in double valve replacement for prosthetic valve endocarditis.

A 52-year-old man, who underwent double valve replacement for native valve infectious endocarditis, developed prosthetic valve endocarditis (PVE) at nine months after the initial operation. Operative findings revealed a wide aortic annular abscess, which extended through the intervalvular fibrous body to the mitral annulus. The infected mitral valve was excised through the atrial septum.

Comparison between early and late prosthetic valve endocarditis: clinical characteristics and outcomes.

Background And Aim Of The Study: Prosthetic valve endocarditis (PVE) is considered a time-related event. The study aim was to compare the clinical characteristics and outcomes of early- and late-onset PVE, and to investigate potential preventive measures for each condition.

Methods: A total of 47 consecutive patients undergoing surgery for PVE between January 1986 and December 2011 were analyzed retrospectively, and classified as an early-onset group (n = 26; PVE occurring within 12 months after previous surgery) and late-onset group (n = 21; PVE occurring after 12 months).

Hybrid procedure for a Kommerell's diverticulum in a right-sided aortic arch.

A rare case of an aneurysmal Kommerell's diverticulum in a right-sided aortic arch was successfully treated using a hybrid procedure comprising total arch replacement and percutaneous stent grafting. A 65-year-old man with dysphagia was diagnosed with an ectatic right-sided aortic arch and a saccular aneurysm of the Kommerell's diverticulum. Since its radical resection during a single surgery was unfeasible because of its complex configuration, a 2-stage procedure was adopted.

Isolated aneurysm of the proximal right subclavian artery treated with consideration toward cerebral circulation and vasculature.

A 65-year-old man with an isolated aneurysm of the proximal right subclavian artery (SCA) (diameter, 50 mm) was successfully treated with a deliberate surgical strategy described here. Because of the occluded left vertebral artery (VA) and poor development of the circle of Willis, the distal portion of the right SCA was bypassed from the ascending aorta before resecting the aneurysm in order to maintain blood flow to the brain through the right VA. Consequently, the patient recovered without neurological complications.

Aortic prosthetic graft infection accompanied with esophagomediastinal fistulas: A case report.

Prosthetic graft infection is difficult to diagnose early, and hence, is associated with high mortality and morbidity rates. A 63-year-old man who had undergone surgical prosthetic replacement for an inflammatory thoracic aortic aneurysm 10 months previously visited our emergency room, complaining of chills, shivering, frequent vomiting, and back pain. He was diagnosed with severe sepsis, and a blood culture detected and .

[Lethal cholesterol crystal embolization syndrome after operation for abdominal aortic aneurysm].

A 70-year-old man underwent graft replacement for infrarenal abdominal aortic aneurysm, 50 mm in diameter. Postoperatively, he suffered from bilateral lower extremital ischemia. Although he underwent emergency embolectomy of both legs under general anesthesia, severe purplish discoloration of the distal lower extremities developed, and acute renal dysfunction occurred.

Repair of aortoesophageal fistula after total aortic arch grafting.

This case report describes the repair of an aortoesophageal fistula caused by a previously placed aortic arch graft. A 62-year-old man underwent total aortic arch graft replacement one year ago. He was readmitted with hematemesis and a high fever.

Left atrial appendage contributes to left atrial booster function after the maze procedure: quantitative assessment with multidetector computed tomography.

Objective: Although the left atrial appendage (LAA) is excised to prevent thrombosis in the maze procedure, it remains unclear whether LAA is retained in expectation of LAA booster function. Therefore, we quantitatively assessed LAA size and function after the maze procedure in patients with chronic atrial fibrillation (AF) and mitral valve disease (MVD), and compared with those in patients with sinus rhythm after coronary artery bypass grafting (CABG).

Methods: We studied 23 patients (maze group: 65.

Chordal translocation for ischemic mitral regurgitation may ameliorate tethering of the posterior and anterior mitral leaflets.

Objective: Treatment of ischemic mitral regurgitation accompanied by strong tethering remains a challenge. Undersized ring annuloplasty is frequently associated with residual/recurrent mitral regurgitation caused by mitral-leaflet tethering. Although chordal cutting is a simple procedure for repairing severe tethering of the anterior mitral leaflet, it often affects mitral valvular-ventricular continuity.

Differences in mitral valve-left ventricle dimensions between a beating heart and during saline injection test.

Objective: Saline injection test performed during mitral valvuloplasty is popular; however, discrepancies are sometimes noticed between the 'naked eye' findings of regurgitation during the saline injection test and the echocardiographic findings after surgery. These discrepancies may arise due to the geometric differences in the mitral valve-left ventricular complex between the saline-injected left ventricle (LV) and the beating LV. Therefore, to elucidate these differences, we compared the three-dimensional geometries between these two conditions.

Chordal "translocation" for functional mitral regurgitation with severe valve tenting: an effort to preserve left ventricular structure and function.

Objective: The chordal cutting method is performed for mitral valve tenting in functional mitral regurgitation, such as ischemic mitral regurgitation. However, the method may interfere with the mitral valvular-ventricular continuity. To maintain the continuity and the natural force direction between the papillary muscles and the mitral annulus after chordal cutting, we developed "translocation" of the secondary chordae tendineae.

Reoperation of the Kay-Shiley disc valve 35 years after replacement.

The Kay-Shiley disc valve (Shiley Inc, Irvine, CA) was manufactured in 1965 and is no longer in clinical use due to its high incidence of thromboembolism. We report a case of tricuspid valve replacement with the Kay-Shiley valve 35 years previously. The valve was replaced successfully with a St.

Successful treatment of chronic thromboembolic pulmonary hypertension with inhaled nitric oxide after right ventricular thrombectomy.

We report a case of a 42-year-old male with chronic thromboembolic pulmonary hypertension. His preoperative examination revealed severe hypoxemia (PaO2 48 mmHg, PaCO2 34 mmHg in room air), a mass in the right ventricle and severe pulmonary hypertension (pulmonary arterial pressure 70/33 mmHg). We successfully performed right ventricular thrombectomy to prevent further embolization from the right ventricular thrombus.
