We report on a rare case of combined unilateral atresia of the proximal right pulmonary artery (PA) and left patent ductus arteriosus (PDA). A 46 year-old female patient with known PDA and associated advanced pulmonary arterial hypertension presented with progressive hemoptysis and increasing exertional dyspnea. Computed tomography of the chest ...

The echocardiogram is the preferred procedure in confirming the diagnosis and characterizing PDA. Doppler echocardiography proved more efficient than clinical examination in grading PDA and becomes essential in the evaluation of clinically significant ductal shunting. Four patterns of PDA shunt can be identified using pulsed Doppler echocardiography: pulmonary hypertension, growing ...

OBJECTIVE: To report our experience with transcatheter occlusion of antegrade pulmonary blood flow (APF) for postoperative complications of cavopulmonary anastomosis (BCPA). BACKGROUND: It has been suggested that limited APF enhances pulmonary arterial growth in patients undergoing BCPA. However, APF may result in suboptimal postoperative hemodynamics and sequelae such as SVC ...

It has been generally assumed that the outflow tract of the chondrichthyan heart consists of the conus arteriosus, characterized by cardiac muscle in its walls. However, classical observations, neglected for many years, indicated that the distal component of the cardiac outflow tract of several elasmobranch species was composed of tissue ...

Platypnea-orthodeoxia is a rare clinical syndrome characterized by hypoxemia induced during upright posture. Multiple mechanisms have been proposed to explain this clinical entity, usually involving posture-provoked intracardiac or transpulmonary shunting. In many cases, however, a single etiology may not be evident, and multiple factors are likely contributory. We herein describe ...
