As a complication of myocardial ischemia, severe elongation of the anterior papillary muscle with resultant mitral valve insufficiency is a rare clinical finding. Using echocardiography, we accurately diagnosed this condition in a 75-year-old man. The patient underwent successful plication of the elongated anterior papillary muscle and the implantation of polytetrafluoroethylene neochordae tendineae.

Takotsubo cardiomyopathy mimics acute coronary syndrome and is accompanied by reversible left ventricular apical ballooning in the absence of angiographically significant coronary artery stenosis. In Japanese, "takotsubo" means "fishing pot for trapping octopus," and the left ventricle of a patient diagnosed with this condition resembles that shape. Takotsubo cardiomyopathy, which is transient and typically precipitated by acute emotional stress, is also known as "stress cardiomyopathy" or "broken-heart syndrome."Herein, we describe the clinical angiographic characteristics of 4 patients who exhibited this syndrome, and we review the existing literature and propose reasons to conduct prospective studies.

Case Reports
Systemic venous thrombosis after recombinant factor VIIa in the control of bleeding after cardiac surgery.
Recombinant factor VIIa has been licensed in the United Kingdom since 1996 for the control of bleeding in hemophilic patients who are actively bleeding or are about to undergo surgery. Medical practitioners are also applying recombinant factor VIIa toward the control of bleeding in patients without hemophilia. ⋯ Herein, we report the case of a 73-year-old woman who underwent major coronary surgery and developed fatal systemic venous thrombosis after recombinant factor VIIa was used in an attempt to control her severe postoperative bleeding. We review the medical literature and discuss the risks of using recombinant factor VIIa to control severe bleeding after cardiac surgery.

Comparative Study
Left ventricular aneurysmal repair within 30 days after acute myocardial infarction: early and mid-term outcomes.
For safe resection, left ventricular aneurysmal repair after acute myocardial infarction is usually delayed. However, delaying surgery may not be possible or prudent in some patients who are clinically unstable after acute myocardial infarction. We retrospectively reviewed the early and mid-term outcomes of left ventricular aneurysmal repair in patients who had experienced acute myocardial infarction <30 days before the repair. ⋯ Postoperative New York Heart Association functional class improved similarly in both groups. We infer that left ventricular aneurysmal repair with coronary revascularization < 30 days after a recent myocardial infarction is a feasible procedure, with acceptable morbidity and mortality rates. Our mid-term results were comparable with those for patients who underwent this surgery > or = 30 days after acute myocardial infarction.

The redesigned HeartMate II, an axial-flow left ventricular assist device, is simpler, smaller, and easier to operate than are pulsatile pumps. These design characteristics should make the HeartMate II more reliable and durable and broaden the eligible population base. We implanted the HeartMate II in 43 patients (average age, 42 yr). ⋯ Of the 10 patients in whom the HeartMate II replaced a failed HeartMate I, 8 were discharged from the hospital. We have seen excellent results with use of the HeartMate II. Functional status and quality of life have greatly improved in patients who survived the perioperative period.
