The use of Transmyocardial Laser Revascularization (TMLR) as a strategy to treat unstable angina has been reported in many studies. We analyze its safety and effectiveness in combined procedures (CABG + TMLR). ⋯ Incomplete coronary revascularization may be complemented with TMLR in the areas in which CABG is not possible without increased mortality. This technique may avoid postoperative unstable angina due to residual ischemic areas.

Cardiac contusion may cause disorders of impulse formation and propagation in the specific conduction system. Transient complete atrioventricular block following a nonpenetrating chest trauma is a rare complication. We describe the case of a patient who presented a transient complete atrioventricular block, and later a transient right bundle branch block and a left anterior hemiblock, following a nonpenetrating chest trauma due to a car accident. The difficulty for diagnosing myocardial contusion is pointed out, and the usefulness of the electrophysiological study for detecting baseline conduction system disorders is discussed.

Case Reports
[Transesophageal echocardiographic diagnosis of a ruptured sinus of valsalva aneurysm with right atrium fistula].
Congenital aneurysms of the sinus of Valsalva are relatively rare, tending to be most frequent in adults. Untreated, there is a substantial risk of complication due to bacterial endocarditis and, if rupture occurs, rapid and progressive cardiac insufficiency is fatal at short term. ⋯ Catheterization and angiography were not definitive. Echocardiographic data are described and a bibliography of relevant research articles is provided.

Morbidity and mortality in elective valve surgery is still significant. The main cause of death in these patients is cardiogenic shock, of which the most frequent etiology is acute myocardial infarction (AMI) with Q wave in the ECG. However, there are patients with cardiogenic shock without Q wave in the ECG and with rises in CK-MB enzyme that makes us suspect non-Q wave AMI. ⋯ This study suggest the possibility of in vivo identification of non-Q wave perioperative AMI, an entity with important morbidity and mortality in our series, with a simple determination of cardiac troponin I 14 hours after surgery.

Out of hospital sudden death constitutes a major sanitary problem. Early diagnosis and treatment are considered as the most important factors related with short term prognosis. However, there is little information about the outcome of patients admitted to the hospital after a successful recovery from an episode of sudden death outside the hospital. The objective of this study was to analyze the prognosis of patients who initially recovered after an episode of out-of-hospital cardiac arrest and who were admitted to the coronary or intensive care unit. ⋯ Up to 30% of the patients admitted after an episode of extrahospital cardiac arrest were discharged alive and without severe neurological damage. Advanced age, functional class IV and the delay of cardiopulmonary resuscitation are related to a unfavorable outcome.
