Unexpected massive pleural effusion leading to discovery of left subclavian artery rupture during transcatheter aortic valve implantation
This report describes a massive pleural effusion that led to the discovery of subclavian artery rupture causing hemodynamic shock. Hemodynamic instability in this patient was caused by hypovolemic and obstructive shock, with a pleural perfusion caused by subclavian artery rupture. Monitoring via transesophageal echocardiography during the procedure enabled early discovery of the massive pleural effusion. Subsequent covered stent implantation stabilized the subclavian artery rupture, and the patient became hemodynamically stable. As subclavian artery rupture can occur during trans-subclavian TAVI, the presence of calcificat...

A case of desmoplakin mutation and delayed arrhythmogenic right ventricular cardiomyopathy/dysplasia after atrial septal defect closure
We describe the case of a 67-year-old man who was diagnosed as having ARVC/D with a desmoplakin mutation that appeared after occlusion of an atrial septal defect (ASD). He underwent patch closure surgery for ASD at the age of 54 years. Four years later, he underwent catheter ablation for multifocal atrial tachycardias. Because of pre-syncope and inducible sustained monomorphic ventricular tachycardia, an implantable cardioverter defibrillator was implanted. When he was admitted for worsening heart failure at the age of 61 years, the desmoplakin mutation was detected with progressive left ventricular (LV) dysfunction...

Coronary stent infection: Interesting cases with varied presentation
In this study, we describe two such cases of coronary stent infection but with varied presentation. The first patient presented with recurrent stent thrombosis and acute coronary syndrome while the second patient was erroneously diagnosed as having tubercular pericarditis and was started on anti-tubercular therapy. Due to their possible fatal outcome, we herein report our experience with this uncommon clinical entity to help in rapid diagnosis and treatment. (Source: Journal of Cardiology Cases)

Paradoxical embolism caused by ovarian vein thrombosis extending to inferior vena cava in a female with uterine myoma
We report the case of a 42-year-old female who was hospitalized for stroke. Detailed investigations revealed the existence of a PFO, pulmonary embolism, and ovarian vein thrombosis extending to inferior vena cava. She had a uterine myoma to be operated on but no other thrombophilic disorders. Anticoagulation therapy with direct oral anticoagulant successfully reduced the thrombus and prevented the recurrence of paradoxical embolism. (Source: Journal of Cardiology Cases)
