A mechanical heart valve thrombosis during pregnancy is one of the most lethal conditions to experience due to its detrimental effects on both mother and fetus. Cardiac surgery during pregnancy is reserved for cases where medical treatment fails due to harmful maternal and fetal effects. A 24-year-old female in the 38th week of pregnancy was admitted to the emergency room with aggravated dyspnea, tachypnea, and palpitations. Read More

Although transfemoral transcatheter aortic valve replacement (TAVR) is the gold standard, this approach is not be feasible in approximately 15% of the patients. Trans-carotid TAVR may be less invasive than transthoracic routes for TAVR, and has been associated with encouraging results. Further prospective studies comparing alternative access routes in patients with whom transfemoral TAVR is not feasible are warranted, to propose an evidence-based algorithm guiding the physician decision.
