Partial Anomalous Pulmonary Venous Return Presenting in Adults: A Case Series With Review of Literature

Medical Management of Isolated Partial Anomalous Pulmonary Venous Connection With Symptomatic Right Ventricular Failure and Pulmonary Hypertension

Partial anomalous pulmonary venous connection (PAPVC) is a rare congenital heart disease in which one or more pulmonary veins drain into the systemic venous circulation. The abnormal connection between the pulmonary vein and the right atrium can result in a right-sided volume overload due to a left-to-right shunt, followed by eventual right-sided pressure overload and right ventricular failure. PAPVC is usually associated with an atrial septal defect but can present as an isolated finding. We present a case of isolated PAPVC resulting in right heart failure and predominantly pre-capillary pulmonary hypertension. We discuss the challenges in the diagnosis and medical management of isolated PAPVC and highlight the clinical and hemodynamic indications for pulmonary vasodilators and diuretics.

An Unexpected Diagnostic Twist in an Elderly Patient: No Heart Failure With Preserved Ejection Fraction

Heart failure with preserved ejection fraction (HFpEF) is considered to be the dominant cause of dyspnea and pulmonary hypertension (PH) in elderly patients with preserved left ventricular systolic function and cardiovascular comorbidities. However, it is important to keep in mind that left ventricular diastolic dysfunction is not the only possible cause of PH in cases of late-onset clinical manifestation. A multiparametric approach is essential for accurate diagnosis and therapeutic decision-making. A 74-year-old patient was admitted due to progressive dyspnea and suspicion of PH. Given the patient's risk profile, HFpEF and concomitant post-capillary PH were anticipated. Despite negative findings on CT angiography and transesophageal echocardiography, right heart catheterization was performed, revealing discrepant oxygen saturations in the superior vena cava and right atrium. A partial anomalous pulmonary venous return and an atrial septal defect were identified through cardiac magnetic resonance imaging.

Cardiac Computed Tomography as a Diagnostic Modality for the Assessment of Complex Congenital Heart Disease Management

Here, we present a case of partial anomalous pulmonary venous return with the superior type of sinus venosus atrial septal defect. This case also had unusually persistent left-sided superior vena cava, which could not be diagnosed well in preoperative transthoracic echocardiography and required contrast-enhanced cardiac computed tomography scanning for proper diagnosing, operative planning, and avoidance of intraoperative problems. Postoperative, cardiac computed tomography scanning was also done to confirm adequate management.
