[Surgical repair of postinfarction ventricular septal perforation by endocardial patch with infarction exclusion].

Unlabelled: We evaluated the surgical results of postinfarction ventricular septal perforation by endocardial patch with infarction exclusion.

Materials And Methods: We reviewed 8 patients complicating AMI who underwent surgical treatment at our institution from July 1997 to August 2000 (6 males, 2 females, mean age 73.9 +/- 9, range 57-87).

[Mid-term results of double valve (mitral-aortic) replacement for cases with poor LV function].

Unlabelled: From March 1989 to July 2000, 82 patients have received the aortic-mitral replacement in our hospital. Among these patients, 11 patients had left ventricular ejection fraction less than 40%. We evaluated the mortality, the cause of death, postoperative complications and mid-term results of these patients.

[Mid-term results of triple valve operation].

Unlabelled: From January 1995 to August 2000, 34 patients received the triple valve operation in our hospital. We evaluated the mortality, the cause of death, postoperative complications and mid-term results in these patients. Five-years'survival rate was determined by means of the Kaplan-Meire method.

Time-dependent morphologic characteristics in angiographic chronic total coronary occlusions.

Intravascular ultrasound analysis of 70 chronic total occlusions (CTOs), conducted either before intervention or following dilation of a 1.5-mm balloon, showed that older CTOs have more complex plaque composition including a larger calcific burden. This may explain the adverse revascularization profile of older CTOs.

Successful endovascular repair of juxtarenal and suprarenal aortic aneurysms with a branched stent graft.

This case report describes a new technique for repairing pararenal aortic aneurysms with a transluminally placed triple-branched stent graft with sidearms extending into the superior mesenteric artery and renal arteries. Endovascular repair with the branched stent graft was attempted in two patients with a pararenal aortic Aneurysm. Stent grafting was technically successful in both patients.

[Clinical study of aortic root replacement].

From 1990 to 1999, 19 patients underwent aortic root replacement. Annulo-aortic ectasia was observed in 14 patients, aortic dissection in 4, and aortitis in 1. Mean aortic cross-clamp times and cardiopulmonary bypass times were 163 +/- 44 and 247 +/- 99 min, respectively.

Measurement of postsystolic shortening to assess viability and predict recovery of left ventricular function after acute myocardial infarction.

Objectives: We sought to determine whether left ventricular (LV) postsystolic shortening in the region of acute myocardial infarction (MI) predicts functional recovery after primary angioplasty.

Background: Previous studies in experimental animals have shown that postsystolic shortening during temporary coronary occlusion predicts functional recovery after reperfusion.

Methods: Contrast ventriculography was performed on 35 patients with acute MI before and immediately after angioplasty, and one day, one month, three months and one year later.

[Eighty cases of minimally invasive direct coronary artery bypass grafting].

Between March 1996 and November 1997, 80 patients with a mean age of 70 years (45-89) have undergone minimally invasive direct coronary artery bypass grafting via anterior minithoracotomy or subxiphoid incision with left internal thoracic artery and right epigastric artery using local coronary occlusion on a beating heart. Cardiac-related hospital mortality was 2.5% (2/80).

Variability in frame by frame analysis of left ventricular wall motion from contrast angiograms.

Background: Measurement of the timing of left ventricular (LV) wall motion, of asynchrony, and of diastolic function from contrast angiograms requires delineation of the endocardial border frame by frame through the cardiac cycle. This study was performed to determine the magnitude of intraobserver and interobserver variability in manual border tracing, and to measure the impact of this variability on the derived functional parameters.

Methods: The contrast ventriculograms of 25 patients with coronary artery disease (CAD) or with normal coronary arteries were analyzed frame by frame, by two observers or twice by the same observer.

[The causes and management of ischemic mitral regurgitation].

Ischemic mitral regurgitation (IMR) is recognized as one of the complications of coronary artery disease. The aim of this study is to evaluate the causes and surgical management of IMR. From October 1986 to March 1995, 443 of patients underwent isolated coronary artery bypass grafting (CABG).

[A case of coronary perforation after directional coronary atherectomy].

Directional coronary atherectomy was performed on a 69-year-old female with angina pectoris. She suffered from coronary perforation as a result of cardiac tamponade and shock. Pericardial drainage and hemostasis were performed immediately using a perfusion catheter.
