Effect of prosthesis-patient mismatch on survival after aortic valve replacement using mechanical prostheses in patients with aortic stenosis.

Background: This study assessed the effects of prosthesis-patient mismatch (PPM) after aortic valve replacement (AVR) using mechanical prostheses in patients with aortic stenosis.

Methods: A total of 124 patients with aortic stenosis who underwent AVR with mechanical prostheses were followed (mean 9.1+/-4.

Successful surgical repair of an elderly patient with tetralogy of Fallot: a case report.

We report on a rare case of a 61-year-old female patient with tetralogy of Fallot who had a late radical repair. The patient had no previous surgical interventions, and her postoperative course was uneventful. One year after the repair, the patient is doing well and has no symptoms of cardiac failure.

[New method for accurate ECG trigger of intraaortic balloon counterpulsation during off-pump coronary artery bypass surgery].

Background: Retractions of the heart required for exposure and construction of distal anastomoses often decrease R-wave amplitude of ECG and interfere with intraaortic balloon pump (IABP) trigger during off-pump coronary artery bypass (OPCAB). Missing R wave trigger results in asynchronous work of IABP and probably produces hemodynamic instability. We report our early experience with a new interface BPI 202 (Osypka Medical, Inc.

Axilloaxillary bypass for the treatment of subclavian artery stenosis complicated by bilateral common carotid artery occlusion: technical case report.

Objective And Importance: We successfully treated a patient with stenosis of the left subclavian artery, complicated by bilateral common carotid artery occlusion, via axilloaxillary bypass surgery.

Clinical Presentation: A 67-year-old patient with a history of hypertension and cerebral infarction underwent neck irradiation for treatment of a vocal cord tumor. Three months later, he began to experience transient tetraparesis several times per day.
