Effects of patient-prosthesis mismatch on postoperative early mortality in isolated aortic stenosis.

Background And Aim Of The Study: Small valve size and patient-prosthesis mismatch (PPM) generate high postoperative transvalvular gradients and may decrease both early and long-term survival. The study aim was to evaluate whether mismatch affected early mortality after aortic valve replacement (AVR) for isolated aortic stenosis (AS).

Methods: A total of 701 patients (437 males, 264 females; mean age 53.

Cardiovascular reoperations in Marfan syndrome.

Background And Aim Of The Study: The purpose of this study is to analyze the outcome results of reoperations in Marfan syndrome patients.

Methods: Between 1985 and December 2004, 49 patients with Marfan syndrome were operated for aortic aneurysms. Of these 49 patients, 9 (18,4%) required > or =1 reoperations after a mean duration of 32.

Valvular surgery in Behcet's disease.

Background: Behcet's disease is a chronic inflammatory disease with a relapsing course. Behcet's disease affects many systems and causes hypercoagulability, and detection of an intracardiac mass in a Behcet patient should raise the question of an intracardiac thrombus. We analyzed our patients with Behcet's disease operated for valvular disease.

Aspartate and glutamate-enriched cardioplegia in left ventricular dysfunction.

Background: The effects of exogenous L-aspartate and L-glutamate-enriched cardioplegia on postoperative left ventricular functions after coronary artery bypass surgery in patients with moderate left ventricular dysfunction (left ventricular ejection fraction [LVEF]= 30-40%) were studied.

Methods: In this prospective randomized study, 22 patients with moderate left ventricular dysfunction (mean LVEF = 37.27%+/- 3.

Complete off-pump coronary revascularization in patients with dialysis-dependent renal disease.

Patients who have dialysis-dependent renal disease frequently present with coronary artery disease but are considered at high risk for coronary artery bypass grafting. From 1 September 2000 through 31 August 2003, we performed complete off-pump coronary revascularization in 6 patients who had end-stage dialysis-dependent renal failure, and we prospectively studied the perioperative and early postoperative results. The effect of off-pump coronary artery bypass grafting on mortality, morbidity, postoperative complications, and transfusion requirements in this group of patients was investigated.

[Surgical treatment of iatrogenic cardiac traumas induced by heart catheterization].

Background: A retrospective evaluation was made on iatrogenic cardiac traumas requiring surgical treatment, that were induced by cardiac catheterizations and interventions performed within a 17-year period.

Methods: A total of 64,911 patients underwent cardiac catheterizations and interventions from 1985 to 2002. Complications of iatrogenic cardiac traumas induced by these interventions were examined together with the surgical treatment performed within 24 hours after catheterization.

Mitral clefts and interatrial septum defects: 15-year results.

Between 1985 and 2002, 60 patients (58% female) with a mean age of 20.3 +/- 12.1 years (range, 2-55 years) were treated for anterior mitral leaflet cleft.
