Simultaneous aortic valve replacement and pectus excavatum correction in a 76-year-old man.

A 76-year-old man was admitted to our department to undergo surgical treatment for aortic valve regurgitation. On physical examination, a bowl-shaped concavity was noted. Chest computed tomography revealed left-sided heart displacement by severe pectus excavatum with a Haller index of 6.

Aortic valve replacement after previous coronary artery bypass grafting: a case report.

We experienced a case of aortic valve replacement after previous coronary artery bypass grafting with patent bypass grafts. Based on the retrosternal anatomy assessed by preoperative angiography and thoracic computed tomography, aortic valve replacement was performed through a median resternotomy. After careful dissection of the right side of the heart and the ascending aorta, cardiopulmonary bypass was established with cannulation of the ascending aorta and bicaval venous cannulation.

Gum chewing enhances early recovery of bowel function following transperitoneal abdominal aortic surgery.

Background And Purpose: Postoperative bowel dysfunction is still a major unsolved problem following transperitoneal abdominal aortic surgery. We conducted this study to establish if gum chewing during the postoperative period promotes recovery of bowel function following abdominal aortic surgery.

Methods: The subjects were 44 patients who underwent elective abdominal aortic surgery.

Coronary artery bypass grafting in patients with pulmonary aspergillosis.

Cardiovascular surgery in patients with pulmonary aspergillosis has been rarely reported. Coronary artery bypass grafting (CABG) for three cases of angina pectoris with pulmonary aspergillosis was successfully performed. Patients were discharged from our hospital without any complications of invasive Aspergillus cardiovascular infection.

A new hydrocolloid dressing prevents surgical site infection of median sternotomy wounds.

Purpose: This prospective and semi-randomized study was conducted to clarify the effectiveness of a new hydrocolloid dressing placed over median sternotomy wounds using an occlusive dressing technique.

Methods: The subjects were 253 patients undergoing coronary artery bypass grafting (CABG), who were randomized to receive either the new hydrocolloid dressing (Karayahesive, n = 117) or a polyurethane foam dressing (Tegaderm plus Pad, n = 136) immediately after sternal wound closure. Karayahesive was left in place for 7 days, whereas the Tegaderm plus Pad was removed on postoperative day (POD) 2 and replaced with an adhesive wound dressing until POD 7.

[Clinical outcome of the operation using deep hypothermic cardiopulmonary bypass with intervals of circulatory arrest in thoracoabdominal aortic aneurysm].

Deep hypothermic cardiopulmonary bypass with intervals of circulatory arrest has been used for protection of the spinal cord during operations for thoracoabdominal aortic aneurysm (TAAA) in our hospital. We examined the effect of this adjunct this time. We studied 15 patients who were operated using deep hypothermic cardiopulmonary bypass with intervals of circulatory arrest among 19 patients with the TAAA who we performed the operations from 1995 through 2003.

Left atrial thrombus without mitral valve disease in a patient with nephrotic syndrome: report of a case.

Left atrial (LA) thrombi are rarely seen in patients without mitral valve disease. We report the case of a 71-year-old man found to have a large LA thrombus without mitral valve disease. The patient also suffered from atrial fibrillation and nephrotic syndrome (NS), and had a history of transient ischemic attack.

[Effects of colforsin daropate hydrochloride in patients undergoing coronary artery bypass surgery].

The effects of Adehl, colforsin daropate hydrochloride, on hemodynamics were studied in patients undergoing cardiac surgery. Twenty-six patients who underwent coronary artery bypass grafting were divided into two groups according to the intraoperative administration of Adehl. The control group (n = 14) received no Adehl treatment and the Adehl group (n = 12) received Adehl infusion immediately after anesthesia induction (0.

Cardio-aortic operation in octogenarians.

Objective: Aging of the population is a current phenomenon in Japan, and life expectancy at 80 years old is getting longer. So we reviewed cardio-aortic operations on octogenarians at our institution.

Subjects And Methods: Thirty-three consecutive octogenarian patients who had undergone cardio-aortic operations from 1992 to 1998 were studied.

Biological activity of endogenous atrial natriuretic peptide during cardiopulmonary bypass.

To evaluate the effect of cardiopulmonary bypass (CPB) on atrial natriuretic peptide (ANP) biological activity in patients undergoing cardiac operations, we conducted a prospective study. Ten patients undergoing mitral valve surgery were enrolled. Plasma levels of ANP and cyclic guanosine monophosphate (cGMP), hemodynamic variables, and renal function parameters were assessed perioperatively.

Effects of intraoperative administration of atrial natriuretic peptide.

Background: Biological activity of endogenous atrial natriuretic peptide (ANP) may decrease during cardiopulmonary bypass. To evaluate the effects of intraoperative administration of exogenous ANP in patients undergoing cardiopulmonary bypass, we conducted a prospective randomized study.

Methods: Eighteen patients undergoing mitral valve surgery were randomized to receive either ANP treatment (ANP group; n = 9) or no ANP treatment (control group; n = 9).

Plasma exchange for hyperbilirubinemia following implantation of a left ventricle assist system: a case report.

A 49-year-old patient with end-stage dilated cardiomyopathy underwent implantation of a left ventricular assist system (LVAS). Although the systemic circulation seemed to be improved, the serum total bilirubin (Tbili) level increased sharply in the early postoperative period (preoperative Tbili, 5.7 mg/dl; postoperative day 3, 33.

[Influence of milrinone on internal mammary artery grafts].

To evaluate the effects of milrinone on blood flow in the left internal mammary artery (LIMA) grafts and hemodynamic variables, we conducted a prospective randomized study. Twenty-four patients undergoing coronary artery bypass grafting were randomized to receive milrinone treatment (Milrinone; n = 12) or no milrinone treatment (Control; n = 12). Milrinone was given after induction of anesthesia at a speed of 0.

Valve surgery in elderly patients 70 years or older: early and late results.

Between April 1986 and March 1997, 75 patients (Group E) who were 70 years or older underwent valvular operations, and another 73 patients who were under 70 years constituted a comparison group (Group Y). Valve replacement was performed on 131 patients (Group E; 65 patients, Group Y; 66 patients), reparative procedures on 11 patients (Group E; 7, Group Y; 4), and aortic root replacement on 5 (Group E; 3, Group Y; 2). Coronary artery bypass grafting was concomitantly performed on 13 patients (Group E; 7, Group Y; 6).

[A case report of atrial septal defect with quadricuspid pulmonary valve].

We reported the successful case of valvuloplasty on the quadriscuspid pulmonary valve which had pulmonary regurgitation. A 38-year-old woman was admitted with the complaint of palpitation. Atrial septal defect and pulmonary regurgitation were revealed preoperatively by the cardiac catheterization and doppler echocardiography.

[Four operated cases of traumatic tricuspid regurgitation].

Four cases of tricuspid regurgitation due to nonpenetrating chest trauma are presented. From five to twenty five years after the initial blunt chest trauma, they were admitted because of dyspnea or palpitation on exertion. In all cases echocardiogram showed severe tricuspid regurgitation and enlarged right atrium and ventricle.

[Combined operation for renovascular hypertension and ischemic heart disease].

We have experienced two patients of ischemic heart disease associated with renovascular hypertension. Patient 1 (60-year-old man) underwent LV aneurysmectomy and triple aortocoronary bypass grafting (saphenous vein to diagonal branch, left internal mammary artery to obtuse marginal branch, and right gastroepiploic artery to right coronary artery). Seventy five days after the initial cardiac surgery endarterectomy for the left renal artery and bifurcated Dacron graft implantation for the iliac artery obstruction were performed.
