Hemodynamic evaluation of the pulmonary arteries and aorta using 4D flow cardiac MRI in children and young adults with dextro-transposition of the great arteries after the arterial switch operation.

Background: Pulmonary artery stenosis, neoaortic dilatation, and neoaortic valve insufficiency are among the most frequent complications of the arterial switch operation for repair of dextro-transposition of the great arteries (d-TGA). It remains difficult to predict which patients will require great arterial reintervention.

Objective: We aimed to characterize hemodynamics within the great arteries using 4D flow MRI in patients with d-TGA after the arterial switch operation.

The Ross procedure for recurrently failed aortic valve procedures.

The Ross procedure provides young patients with unrepairable aortic valve disease with a living pulmonary autograft that confers significant survival benefit and improved quality of life. However, the procedure is complicated, and surgeons can be reluctant to offer it as a solution, especially in complex re-operative scenarios. We present a young patient with symptomatic, severe aortic insufficiency who had undergone two failed aortic valve procedures for congenital bicuspid aortic valve disease within the prior year.

The Value of Repeat 5-HIAA Measurements as a Predictor of Carcinoid Heart Disease: A Prospective 5-Year Follow-Up Study in Patients with Small Intestinal Neuroendocrine Tumors.

Small intestinal neuroendocrine tumors (SI-NETs) are characterized by carcinoid syndrome and carcinoid heart disease (CHD). The aim of the present study was to identify early risk markers for carcinoid heart disease and survival in a prospective median-term follow-up setting. We measured 5-HIAA and cumulative 5-HIAA exposure (Cum-5-HIAA) based on repeated measurements, proBNP, vascular function, hepatic tumor load, and transthoracic echocardiography (TTE) at baseline and during the median 5-year follow-up.

[Double Valves Repair for Mitral and Tricuspid Regurgitation due to Barlow's Disease:Report of a Case].

A 75-year-old man with mitral regurgitation (MR) and tricuspid regurgitation (TR) caused by Barlow 's disease was referred to our hospital. He had a history of persistent atrial fibrillation. Echocardiography showed severe MR with bi-leaflet billowing and functional TR.

A new technique for the treatment of venous popliteal aneurysms using the axillary vein: Medium and long-term results.

Objectives: Venous popliteal aneurysms are a rare but serious disease due to the risk of pulmonary embolism. Aneurysms larger than 20 mm in diameter or with an embolic episode should be treated. The classic surgical technique is the tangential resection of the aneurysm with venorraphy, which raises the risk of recurrence.

[Acute mitral regurgitation causing right-sided pulmonary edema: a case report].

A young female presented to our emergency department with sudden-onset shortness of breath and orthopnea. Her condition rapidly worsened. She developed severe respiratory failure and cardiogenic shock ensued.

Right ventricular to pulmonary arterial coupling as a predictor of survival in patients undergoing mitral valve surgery for mitral regurgitation.

Objectives: Right ventricular-to-pulmonary artery coupling has been associated with outcomes in mitral regurgitation treated by transcatheter approaches. We evaluated right ventricular-to-pulmonary artery coupling as a predictor of survival and postoperative length of hospital stay (LOS) in patients with mitral regurgitation undergoing mitral valve surgery.

Methods: In this retrospective analysis (median follow-up: 5.

Impact of Updated Invasive Right Ventricular and Pulmonary Hemodynamics on Long-Term Outcomes in Patients With Mitral Valve Transcatheter Edge-to-Edge Repair.

Right-sided cardiac catheterization (RHC) is selectively recommended in mitral valve transcatheter edge-to-edge (M-TEER) workup because right ventricle (RV) hemodynamic parameters predict adverse outcomes. This study examines the impact of RV hemodynamics and the prognostic value of the 2022 European Society of Cardiology (ESC) pulmonary hypertension definitions on outcomes after M-TEER. Of 152 patients treated with M-TEER for symptomatic severe mitral regurgitation (MR) between December 2014 and February 2024 at our tertiary center, 71 underwent elective RHC before the procedure.
