Background: Both iatrogenic coronary artery stenosis early after aortic valve replacement and pseudonormalization of inverted T-waves in acute ischemia are rare but well-recognized findings which coincide in this case.
Case Presentation: 10 weeks after aortic valve replacement, a 58-year-old male patient was readmitted with recent onset of unstable angina pectoris. Electrocardiography showed inverted T-waves in leads V2-4 with pseudonormalization during episodes of typical chest pain. Coronary angiography revealed subtotal ostial occlusion of the left anterior descending artery which was successfully treated by percutaneous coronary intervention.
Conclusion: Iatrogenic coronary artery stenosis is a potentially life-threatening complication that can occur early after aortic valve replacement in patients with normal preoperative coronary angiography. T-wave-pseudonormalization during episodes of angina pectoris may lead to misinterpretation in patients at high risk.

Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.

Background: Transcatheter aortic valve replacement (TAVR) is a well-established treatment option for patients with severe aortic valve stenosis; however, clinical valve thrombosis is a major challenge.
Case Summary: A 92-year-old woman underwent TAVR for severe aortic stenosis. One month later, the patient developed acute heart failure.

We report a 75-year-old female with a history of two heart operations: aortic valve replacement (St. Jude Medical 21 mm) at the age of 44 years for severe rheumatic aortic stenosis and mitral valve replacement (Carbomedics 29 mm) at the age of 51 years for rheumatic mitral regurgitation. Decades later, she presented with exertional dyspnea.

Introduction The study aimed to retrospectively evaluate the early patient outcome and left ventricular function after mitral valve replacement with a tilting disc valve and total preservation. Patients and methods This retrospective observational study includes patients who underwent mitral valve replacement using a tilting disc valve with total preservation of mitral valvular and subvalvular apparatus from July 2021 to August 2022 at a single center. Results The data were reviewed retrospectively for age, sex, comorbidities, operating time, aortic cross-clamp time, cardiopulmonary bypass time, preoperative and postoperative left ventricular ejection fraction, mean gradient across the mitral valve, left ventricular diameter, left atrial size, atrial fibrillation, complications, mortality, and early patient outcome.
