Case ReportsPercutaneous stent placement as treatment for an infant with superior vena cava syndrome.
The percutaneous use of stents for the treatment of superior vena cava (SVC) syndrome is well described in the adult population. We report the successful use of intravascular stents to treat an infant with severe SVC syndrome.

Case ReportsCongenital agenesis of the right pulmonary artery.
A 44-year-old woman with recurrent pulmonary infections developed severe hemoptysis. Chest radiography revealed a hypoplastic right lung. Absence of the right pulmonary artery, a very rare congenital anomaly, was demonstrated by computed tomography and cardiac catheterization. Severe pulmonary hypertension in the contralateral lung precluded right pneumonectomy but percutaneous embolization of a large systemic arterial collateral to the right lung provided palliative relief of hemoptysis.

Comparative StudyElective coronary stent implantation in cardiogenic shock complicating acute myocardial infarction: in-hospital and six-month clinical and angiographic results.
Effective treatment of patients with acute myocardial infarction and cardiogenic shock depends on restoring persistent patency of the infarct-related artery. Coronary stenting, reducing abrupt or delayed closure related to dissection and suboptimal result, may improve PTCA results in cardiogenic shock. Eighteen patients (14 males and 4 females, mean age 59 +/- 7 years), referred to catheterization laboratory for acute myocardial infarction and shock, had elective stent implantation during 14 primary and 4 rescue PTCA. ⋯ Stent restenosis rate was 30%, and target lesion revascularization with CABG or re-PTCA was not required in any case. LV function improved from 39% +/- 15% to 51% +/- 15% (P < 0.01). Elective coronary stenting is an effective treatment for acute myocardial infarction complicated by cardiogenic shock and may improve acute and long-term survival.

Transcarotid balloon valvuloplasty for critical aortic valve stenosis at the bedside via continuous transesophageal echocardiographic guidance.
We describe the first two successful cases of transcarotid balloon aortic valvuloplasty for critical aortic valve stenosis in the neonate utilizing continuous transesophageal echocardiographic guidance performed at the bedside. This method obviates the need for transporting a sick and hemodynamically unstable neonate to the catheterization laboratory and additionally reduces costs without compromising clinical care.
