Ruptured penetrating ulcer of the ascending aorta with pulmonary artery compression.

Pulmonary artery involvement has been reported in various degrees of complicated dissection of the ascending aorta. The prognosis remains poor without high-risk surgical intervention, but conservative management can be considered in high-risk cases. We report a case of nonoperative management of an octogenarian who presented with a contained rupture of his proximal ascending aorta, likely from a penetrating atherosclerotic ulcer. It was complicated by extrinsic compression of the pulmonary trunk and transient pulmonary hypertension without features of acute right heart failure. He remained alive at the one-year follow-up.

An unusual cause of pulmonary edema.

Primary cardiac tumors are rare malignancies. Patients may present with congestive cardiac failure due to intracavitary obstruction to blood flow, valvular dysfunction, embolic phenomena, local invasion resulting in arrhythmias, pericardial involvement, constitutional symptoms, or paraneoplastic syndromes. We describe the case of a previously fit 79-year-old woman who presented with acute pulmonary edema due to a large left atrial pleomorphic sarcoma causing severe functional mitral stenosis. She underwent palliative debulking surgery with good symptomatic relief.

Effects of age and gender on left atrial ejection force and volume from real-time three-dimensional echocardiography.

INTRODUCTION: This study was carried out to (i) provide the methodology for determining left atrial (LA) volume, emptying fraction and ejection force (LAEF), from real-time 3-dimensional echocardiography (RT3DE), and (ii) evaluate the effects of age and gender on LA volume and LAEF in a wide age range of healthy participants. MATERIALS AND METHODS: RT3DE was performed in 102 healthy participants (age range, 20 to 80 years). From full-volume data sets, LA endocardial borders were automatically traced and LA volumes were determined. LAEF was calculated as 1/3×mitral annular area × (blood density) × (peak velocity of A wave)(2) according to Newton's law of motion and hydrodynamics; wherein the mitral annular area (MVA) is traced using RT3DE and A is the peak Doppler-derived blood velocity at atrial systole with the sample volume placed at the mitral annulus level. RESULTS: ANOVA analysis revealed that LA volume indices were significantly correlated with age (r = 0.366, P <0.0001 for maximal volume index and r = 0.288, P <0.005 for minimal volume index). LAEF was also significantly positively correlated with age (r = 0.49, P <0.0001). The LA emptying fraction was maintained across ages. LA volume indices and LAEF did not differ significantly with gender. CONCLUSION: Our data can be used as normal reference values for LA volumes and LAEF. We have demonstrated that age is positively related to LA volume indices and LAEF, which suggests that age-dependent cut-off values should be considered in those with heart disease.

Thrombus straddling an atrial septal defect: surgical prevention of massive pulmonary and systemic embolization.

A large thrombus entrapped in an atrial septal defect is a rare condition that can lead to life-threatening systemic and pulmonary embolization. The use of thrombolysis may prove dangerous to the patient. Herein, we describe the emergency surgical management that contributed to a successful outcome in a 67-year-old man who was found to have a 23-cm-long thrombus across an atrial septal defect.
