Functional Mitral Regurgitation Post-Isolated Aortic Valve Replacement

Background: The management of mitral regurgitation during aortic valve replacement remains a complex question. Secondary mitral regurgitation often improves post-aortic valve replacement without mitral valve surgery, but residual mitral regurgitation can significantly affect long-term outcomes. This study investigates the natural history of mitral regurgitation following isolated aortic valve replacement and identifies prognostic factors for persistent mitral regurgitation. Methods: A retrospective study was conducted on 108 patients who underwent isolated aortic valve replacement. Patients were categorized based on mitral regurgitation improvement. Additionally, patients were divided into patient-prosthesis mismatch and non-patient-prosthesis mismatch groups based on the aortic prosthesis. Preoperative and postoperative echocardiographic data were analyzed. Results: In total, 63% of patients showed mitral regurgitation improvement. The improved functional MR group showed significant reductions in peak and mean transvalvular pressure gradients. In contrast, the patient-prosthesis mismatch group had persistent mitral regurgitation improvement in 59.2% of patients. The non-patient-prosthesis mismatch group exhibited significant structural improvements and a reduction in mitral regurgitation severity in 68.6% of patients. Conclusions: The study shows that aortic valve replacement could significantly improve MR when patient-prosthesis mismatch is avoided. This approach maximizes hemodynamic outcomes, mitigates the risk of residual or worsening mitral regurgitation, and potentially reduces the need for additional mitral valve interventions.

Thrombosis of External Carotid Artery after Internal Artery Endarterectomy Causing Ischemic Events

Carotid endarterectomy (CEA) is a widespread and safe procedure associated with very little risk. Only at our hospital surgeons perform nearly 1000 of these surgeries annually, with serious complications occurring extremely rarely[1]. Cerebral ischemic events due to external carotid artery (ECA) thrombosis following a successful internal carotid artery (ICA) endarterectomy is one of such complications. We present a case of ECA thrombosis, following ICA endarterectomy that caused ischemic events.

Rare Cause of Leg Edema after Femoropopliteal Bypass Procedure in Patient with Previously Unrecognized Arteriovenous Fistulas: A Case Report

BACKGROUND: Arteriovenous fistulas (AVFs) are pathological, congenital, or acquired communications between the arterial and venous vascular bed. Asymptomatic AVFs do not require surgical or endovascular treatment; however, if they are symptomatic, they must be treated to relieve the patient of symptoms and cardiovascular disorders. CASE PRESENTATION: Our patient had an undiagnosed AVF that became symptomatic after femoropopliteal bypass surgery. We successfully treated these complications with four cover stents. CONCLUSION: The presence of AVFs should be kept in mind in the case of rapidly developing leg edema after revascularization. Endovascular treatment of symptomatic AVF is a safe and effective treatment modality. Treatment of symptomatic AVFs is not only recommended for improving impaired arterial or venous blood flow, but also for preventing recurrent PE.

Caught Between Heart and Limbs: Navigating the Treatment of Patients With CAD and PAD in an Overwhelmed Healthcare System

Peripheral arterial disease (PAD) and coronary artery disease (CAD) are manifestations of atherosclerosis, affecting a substantial proportion of the population. Despite their interrelation, the prevalence of CAD in severe PAD varies, prompting the need to understand their complex relationship. This study retrospectively analyzes prospectively collected data from a high-volume vascular center to assess CAD prevalence, risk factors, and implications for patients undergoing vascular surgery. Among 667 arterial disease patients, 19.5% underwent coronary angiography, with CAD detected in 61.5% of cases. CAD varied across vascular beds. Decision-making around preoperative coronary angiography and revascularization remains complex, with benefits for high-risk patients still being debated. In accordance with current guidelines, the routine practice of coronary revascularization preceding vascular surgery is generally discouraged. This study underscores the need for risk stratification to identify patients who might benefit from coronary revascularization prior to vascular surgery while adhering to cost-effectiveness and avoiding unnecessary and time-consuming diagnostics in the majority of patients. Patient demographics, risk factors, and clinical presentation were analyzed alongside hospital stay, mortality, and complications. The study highlights the challenges in managing patients with concurrent CAD and PAD and calls for improved protocols for treating this high-risk group.
