IntroductionTransient Cortical Blindness (TCB) is a rare complication of contrast medium use, occurring in 0.3%–1% of cerebral angiographies and 0.008%–0.05% of coronary angiographies. (1) It presents as partial or complete vision loss despite normal neurological and fundoscopic examinations, with no specific abnormalities on imaging. While contrast agents are generally safe and effective, they can induce TCB in rare cases, which typically resolves spontaneously within 2 hours to 14 days. (2) The underlying mechanism of TCB is thought to involve contrast medium leakage into the vertebrobasilar circulation during catheterization, leading to transient neurotoxicity. Here, we report a case of TCB lasting 12 hours following transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS).

The occurrence of hematuria during a right heart catheterization can be a sign of renal perforation, a rare but life-threatening complication that could be developed due to the misdirection of wire into the abdominopelvic venous plexus. We showed this complication could be managed with venoplasty of the common iliac vein.

fifty years old woman with dyspnea of exertion, rupture of sinus Valsalva to right atrium and patent foramen oval in echocardiography referred to our hospital. After device closure of the rupture, she developed orthostatic hypoxemia. Invasive intra-cardiac evaluation confirmed the diagnosis of Platypnea-Orthodeoxia Syndrome which was closed with device

A fifty years old woman with dyspnea of exertion and rupture of sinus Valsalva to right atrium in echocardiography referred to our hospital. After device closure of the rupture, she developed orthostatic hypoxemia. Invasive intra-cardiac evaluation confirmed the diagnosis of Platypnea-Orthodeoxia Syndrome which was managed by device closure for PFO.

COVID-19 causes significant hypoxia along with an inflammatory milieu, which may lead to secondary myocardial infarction and also atherosclerotic plaque rupture. Here we present a case of COVID-19 presented with ACS followed by PTE and CVA.
