Late outcome of 132 Senning procedures after 20 years of follow-up.

Background: Risk factors and rates of reoperation, arrhythmias, systemic right ventricular dysfunction (RVD), and late death after a Senning procedure were investigated.

Methods: One-hundred thirty-two patients underwent a Senning operation between 1977 and 2004 (105 simple and 27 complex transpositions of the great arteries). Mean follow-up time was 19.

Clinical significance of early thrombosis after prosthetic mitral valve replacement: a postoperative monocentric study of 680 patients.

Objectives: The aim of this study was to evaluate the incidence of early thrombosis, its prognostic significance, and the therapeutic implications.

Background: Transesophageal echocardiography (TEE) is the method of choice for detecting symptomless early postoperative thrombosis of prosthetic valves. However, the clinical significance is not yet known.

Surgery for prosthetic valve obstruction. A single center study of 136 patients.

Objectives: Prosthetic heart valve obstruction (PHVO) is a potentially fatal complication of heart valve replacement with mechanical substitute mainly due to thrombosis. The purpose of this report is to present a single-center experience of 136 consecutive patients operated on between 1978 and 2001.

Methods: The diagnosis of PHVO was mainly assessed by fluoroscopy and/or echocardiography.

Management of Nonobstructive Thrombosis of Prosthetic Mitral Valve in Asymptomatic Patients in the Early Postoperative Period: A Study in 20 Patients.

The purpose of the present study was to determine the optimal management of nonobstructive thrombi in the early postoperative period after mitral valve replacement.Twenty cases of early thrombi were revealed by systematic transesophageal echocardiography (TEE) performed 9 days after surgical implantation of 229 St. Jude prostheses.
