Marked enlargement of the right pulmonary artery nineteen years after Waterston operation

Ascending aorta-right pulmonary artery anastomosis: Waterston's operation.

Vicious circle between progressive right ventricular dilatation and pulmonary regurgitation in patients after tetralogy of Fallot repair? Right heart enlargement promotes flow reversal in the left pulmonary artery

BACKGROUND The left pulmonary artery (LPA) contributes more than the right (RPA) to total pulmonary regurgitation (PR) in patients after tetralogy of Fallot (TOF) repair, but the mechanism of this difference is not well understood. This study aimed to analyze the interplay between heart and lung size, mediastinal geometry, and differential PR. METHODS Forty-eight Cardiovascular Magnetic Reson...

Dissection of the right pulmonary artery after blunt trauma.

A 46-year old female patient was admitted after a 5-m height fall. Contrast-enhanced CT scan discovered dissection of the right pulmonary artery (Figs 1 and 2) as well as rib fractures, pneumo-/ haemothorax, pulmonary contusions and pneumomedistinum. The dissection was confirmed by another CT scan 6 days later. The course was nonoperatively and uneventful. Figure 1: CT scan revealed dissection ...

Pulmonary artery size and late functional outcome after Fontan operation.

BACKGROUND Pulmonary artery (PA) growth after a Fontan procedure tends to be suboptimal to somatic growth. This study aimed to investigate whether the PA size affects the late outcomes of the Fontan procedure. METHODS This study enrolled 120 Fontan patients. Their mean age was 19.3 ± 5.6 years. PA size was measured from computed tomographic images. Patients were divided into three groups acco...

Pulmonary artery enlargement in schistosomiasis associated pulmonary arterial hypertension

BACKGROUND Schistosomiasis associated pulmonary arterial hypertension (Sch-PAH) might represent the most prevalent form of PAH worldwide. In Sch-PAH, the presence of aneurismal dilation of the pulmonary artery has been described, although it is still a matter of debate whether on average the pulmonary artery is more enlarged in Sc-PAH than IPAH. METHODS We retrospectively evaluated patients w...
