Left ventricular mass regression after aortic valve replacement with the TTK Chitra™ monoleaflet tilting disc valve.

Objective: To study the extent of left ventricular (LV) mass regression in aortic stenosis after aortic valve replacement with the TTK Chitra™ tilting disc valve.

Methods And Materials: This study included patients with severe isolated aortic stenosis (AS), admitted in our department. They had aortic valve replacement (AVR) with the TTK Chitra™ tilting disc valve, between January 2008 and December 2010.

Pituitary carcinoma with a single metastasis causing cervical spinal cord compression. Case report.

Pituitary carcinoma is rare, with fewer than 100 cases having been reported in the English-language literature. The diagnosis of pituitary carcinoma requires the demonstration of cerebrospinal and/or systemic metastases rather than local invasion. The lesion carries a poor prognosis; fewer than 50% of patients survive beyond 1 year after diagnosis.

Deceleration energy and change in velocity on impact: key factors in fatal versus potentially survivable motor vehicle crash (mvc) aortic injuries (AI): the role of associated injuries as determinants of outcome.

Objective: To examine the difference in force mechanisms between fatal and potentially survivable MVC aortic injuries (AI) compared to non-AI severe thoracic injuries (ST).

Methods: Of 324 autopsied MVC driver or front seat passenger fatalities (1997-2000), there were 43 fatal AI (36 scene deaths, 7 hospital deaths) and 5 additional AI survivors.

Results: Of the 48 AI, there was only a 42% survival for those reaching hospital alive.

Cardiac rupture in acute myocardial infarction: a reassessment.

Cardiac rupture as a complication of acute myocardial infarction (AMI) has been described as occurring infrequently. Because of the recent dramatic decrease in autopsy rates, the authors believe that current studies do not accurately represent the frequency of this catastrophic complication. Autopsy protocols and archived histologic slides of patients with AMI were retrospectively reviewed to determine whether the frequency of cardiac rupture, as a complication of AMI, is altered when a non-hospital-based patient cohort after autopsy is evaluated.
