Transseptal puncture is increasingly utilized in electrophysiology and interventional cardiology. With a wide range of therapeutic indications, incidence of iatrogenic atrial septal defect (iASD) is likely to increase. However, the clinical and hemodynamic significance of iatrogenic atrial septal defect is not clear. We report a case of an 88year old woman with prior transcatheter aortic valve implantation and symptomatic severe degenerative mitral regurgitation. She developed persistent hypoxemia following MitraClip(®) procedure, requiring closure of iASD resulting in immediate recovery of hemodynamics. In here, we discuss the hemodynamic changes following percutaneous mitral valve repair and review the evidence supporting the closure of iatrogenic atrial septal defects.

We present finding of right atrial thrombus concomitant with recurrent left atrial thrombus in a patient diagnosed with rheumatic severe mitral stenosis. Its significance lies in the potential complications associated with right atrial thrombus, including spontaneous or iatrogenic pulmonary embolism or paradoxical systemic embolization, underscoring the importance of thorough imaging.

Article Synopsis
- Interventions for heart conditions using transcatheter techniques can sometimes create an unintended atrial septal defect (IASD), leading to uncertain clinical outcomes.
- An 84-year-old female with heart failure and mitral regurgitation underwent TEER treatment, which resulted in both mitral stenosis and an increasing IASD, negatively affecting her cardiac output.
- Successfully closing the IASD improved her blood pressure and overall condition, suggesting that IASD closure may be beneficial for certain patients after such heart interventions, but careful assessment is necessary.

Article Synopsis
- Total Anomalous Pulmonary Venous Connection (TAPVC) is a rare congenital heart defect seen in newborns, and a unique case was presented involving a young adult who developed recurrent hemorrhagic pericardial effusions despite medical treatment.
- The case highlighted that the young adult had a previously undiagnosed TAPVC, which was successfully treated with surgery, leading to the resolution of his pericardial effusions.
- This situation is noteworthy because the occurrence of hemorrhagic pericardial effusions in adults with unrepaired TAPVC is rare, emphasizing the importance for healthcare providers to consider this possibility in similar cases.
