One of the presentations may be pulmonary hypertension due to a significant left-to-right shunt.4 It is caused by the anomalous systemic pulmonary venous drainage and associated cardiac defects.
The following inclusion criteria were used in this study: (i) congenital PMVSD as shown by echocardiography; (ii) body weight >10 kg and age >2 years; (iii) maximum VSD diameter 20 mm by TTE; (iv) defect located at the 9 to 11 o'clock positions of an analog clock in the short-axis parasternal view by TTE; (v) a distance of 1mm from the PMVSD to the aortic valve; (vi) left-to-right shunt; and (vii) calculated pulmonary vascular resistance <8 Wood units.
Cardiac catheterisation revealed large left-to-right shunt and moderate pulmonary hypertension.
It showed a secundum ASD with a left-to-right shunt, severe PS (maximal gradient= 79 mmHg and maximal velocity= 4.4 m/s) (Figure 1), an enlarged right ventricle (RV) (basal diameter= 4.4 cm), normal left ventricular function and mild tricuspid regurgitation.
The latter was probably facilitated by massive left-to-right shunt and associated severe forward failure.
(b) Color flow mapping of the spontaneous PFO left-to-right shunt. (c) Detection of PFO by real-time three-dimensional transesophageal echocardiography.
An echocardiogram (ECHO) showed a 4 mm midmuscular VSD with a left-to-right shunt. The patient remained asymptomatic but did not follow up with cardiology for three years.
The most significant and common anomaly found is a left-to-right shunt [3].
Another important contributing factor was the PDA, which was revealed in the first Echo at 24 hours of life and persisted open with significant left-to-right shunt until his seventh day of life.
(2) At birth, the infant is asymptomatic but during the early months of life the pulmonary pressure falls below systemic pressure, which results in left-to-right shunt from the higher pressure left coronary arterial system to the lower pressure pulmonary arterial system.

Although PAPVR is often asymptomatic, its recognition may be important because the variability of pulmonary vein drainage to the left atrium may lead to a left-to-right shunt, can be significant in affecting the success of catheter ablation in patients with atrial fibrillation, and should be considered in the preoperative evaluation of patients with lung cancer [3].
