Repair of complex malformations that necessitate restoration of continuity between the right ventricle and the pulmonary arteries can now safely be performed with low morbidity and mortality. Major concerns still remain on the long-term outlook for these patients, and about the durability of the different prostheses used to restore that continuity, whether during initial correction or at the time of reintervention for failure of the conduit or pulmonary regurgitation. In this review, we discuss the salient morphologic features of the right ventricular outflow tract, and then focus on the indications for early and late intervention, current therapeutic options, and outcomes.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is an unwarranted complication associated with high mortality. The current TAVI practices recommend a multidetector computed tomography (MDCT) evaluation of the aortic valve, the left ventricular outflow tract, and the aortic root to determine the conventional risk factors for coronary obstruction like low-lying coronary ostia and narrow sinuses of Valsalva, mandating prophylactic coronary protection or native valve leaflet modification in high-risk patients. Despite optimal anatomy, acute coronary occlusion can still occur due to multiple mechanisms, one of which is coronary embolism due to thrombus, calcium, or native aortic valve fragments.

This study evaluated transcatheter approach for relieving right ventricular outflow tract (RVOT) obstruction using combined non-compliant balloon dilatation of the RVOT and conal artery occlusion in patients with Tetralogy of Fallot (TOF), both uncorrected and post-intra-cardiac repair (ICR) restenosis. A prospective study was conducted from January 2022 to June 2023, including 40 symptomatic patients aged over 12 years with RVOT obstruction in TOF. Exclusion criteria included moderate to severe pulmonary regurgitation.

Introduction: Obstructive hypertrophic cardiomyopathy (oHCM) is a genetic disorder characterized by myocardial hypertrophy, which can obstruct left ventricular outflow. Cardiac myosin inhibitors (CMIs) have emerged as a novel therapeutic agent targeting cardiac muscle hypercontractility.
Objective: To compare the efficacy and safety of CMIs mavacamten and aficamten vs.
