Does severe hyperlactatemia during cardiopulmonary bypass predict a worse outcome?

Introduction: The aim of the current study was to evaluate the impact of increased blood lactate levels during cardiopulmonary bypass (CPB) on immediate results in patients who underwent open heart surgery.

Materials And Methods: We performed a retrospective single-center study on 1290 patients. Adult cardiac surgical patients who underwent valve surgery, coronary artery bypass graft, combined procedure, adult congenital anomalies and aortic surgery were enrolled.

Surgical aspects of thoracic aortic aneurysms: A case series from a real-world setting.

Background: The objective of the present study is to review different surgical features and treatment modalities of thoracic aortic aneurysms.

Methods: This was a retrospective study of 17 patients operated on for thoracic aortic aneurysm in the Department of Cardiovascular Surgery of the Military Hospital of Rabat (Morocco) over a 10-year period, from January 2007 to December 2016. All patients with aneurysms located in the thoracic aorta or extended to the abdominal aorta were included in the study.

[Persistence of the 5 aortic arch associated with interruption of the aortic arch].

We report a case of persistence of the 5th aortic arch associated with total interruption of the aortic arch. This clinical case shows the diagnostic pitfall of the persistence of the 5th aortic arch and its beneficial hemodynamic effect. Preoperative clinical picture was misleading, due to the persistence of femoral pulses and clinical signs of left-to-right shunt via a wide ductus arteriosus.

[Subaortic diaphragm surgery].

Subaortic diaphragm is characterized by a certain clinical latency and low morbi-mortality. Surgery remains the treatment of choice despite the real risk of long-term recurrence. Our study involved 18 patients with subaortic diaphragm operated between April 1994 and March 2011.

A giant aneurysm of ascending aorta revealed by superior vena cava syndrome.

We report a 72 year-old man who presented symptoms of right heart failure and patent superior vena cava syndrome related to a huge ascending aortic aneurysm with a maximal diameter at 11 cm. The patient underwent a successful surgical repair by a modified Bentall operation with good recovery.
