[Death conference: hindsight in heart surgery].

We report eight cases of death or decerebration occurred during major cardiothoracic surgery. The technical aspects that contributed to the failure are analyzed on the basis of the Italian Criminal Code (art. 43).

Left-ventricular diastolic dysfunction during pneumonectomy--a transesophageal echocardiographic study.

Left-ventricular dysfunction, with acute increase in capillary pulmonary pressure, can unexpectedly develop in patients submitted to pneumonectomy. In order to study the morphofunctional modifications induced by pneumonectomy on the left cardiac chambers, we performed intraoperative transesophageal echocardiography (TEE) in 8 patients (7 males, mean age 66 years) undergoing pneumonectomy for lung cancer. No patient had any cardiac involvement before surgery.

[Features and evolution of postoperative pain in patients undergoing thoracotomy].

We examined in this perspective study 30 patients (15 males and 15 females) who undergone classic thoracotomy for lung or mediastinal diseases, without postoperative complications. Intensity and different qualitative components of postoperative pain have been evaluated in the 1st, 3rd, 5th, the day after last pleural drainage removal and 2 months after the operation. All patients answered a schedule adherent to Questionario Italiano del Dolore (QUID).

[Mitral valve replacement with the Björk-Shiley monostrut prosthesis: a 4-year clinical experience].

Mitral valve replacement with Björk-Shiley monostrut prostheses was performed in 142 patients, aged 18 to 73 (mean age: 53.8). A group of 101 patients underwent isolated mitral replacement (group A), while both mitral and aortic (in one case tricuspid) valves were replaced in 41 (group B).

High-dose aprotinin: hemostatic effects in open heart operations.

Two groups of patients were prospectively studied to evaluate the hemostatic effects of high-dose aprotinin in open heart operations. Group A patients (n = 22) received aprotinin during the entire surgical procedure. Group B patients (n = 12) served as controls.
