Culture-negative suppurative endocarditis causing severe mitral valve obstruction: complementary use of transesophageal and transthoracic echocardiography.
Infective endocarditis causes a myriad number of serious complications. Mitral valve obstruction is a rare complication. We report a 48-year-old Asian female who presented with two-week duration of fever and rapidly developed acute pulmonary edema and cardiogenic shock. Sequential transthoracic and transesophageal echocardiography revealed a rapidly growing vegetation on the anterior mitral leaflet with severe stenosis of the valve. All the blood cultures were negative. The patient underwent a successful mitral valve replacement. A review of 21 previously reported cases of mitral valve obstruction from endocarditis demonstrates the poor prognosis of this entity and supports early surgery.

Peripartum acute myocardial infarction: management perspective.
Acute myocardial infarction in pregnancy and puerperium is an uncommon event with substantial morbidity and mortality rates. Atherosclerosis may be the cause, but often the coronary arteries are healthy at angiography. In such cases, the suggested mechanism is a decreased coronary perfusion related to coronary spasm or in situ thrombosis. Most pregnant women who died after myocardial infarction did so at the time of initial infarction, and maternal mortality was greatest if the infarction was late in pregnancy. Increasing cardiovascular stresses of late pregnancy, especially when intensified by parturition, seriously compromise women with ischemic heart disease. Therefore, there should be efforts to limit myocardial oxygen demand throughout pregnancy, and particularly during parturition. It is important for diagnosis to have increased awareness of its possible occurrence. Although principles of management can be generalized, it is necessary to provide individualized care for these high-risk patients by a multidisciplinary team of cardiologists, anesthesiologists, and obstetricians.
