We report a patient who underwent bilateral internal thoracic artery implantation into the myocardium known as a Vineberg procedure 27 years ago. Coronary angiography and Doppler echocardiography revealed patent grafts with total occlusion of all native coronary arteries. We measured flow velocities at rest and under stress conditions with noninvasive ultrasonic Doppler echocardiography. The flow patterns in both grafts were biphasic as in native coronary arteries. Under stress conditions no increase in flow was detectable as a marker of end-stage coronary artery disease with refractory angina pectoris.

Association with Outcome of the Regurgitant-Volume Adjusted Right Ventricular Ejection Fraction in Secondary Tricuspid Regurgitation.

Background: In patients with secondary tricuspid regurgitation (STR), right ventricular ejection fraction (RVEF) may not accurately reflect the actual RV systolic performance since a considerable amount of the RV stroke volume (SV) is regurgitated back into the right atrium. To overcome this limitation, we explored the association with the outcome of the effective RVEF (eRVEF), which accounts for the tricuspid regurgitant volume (RegVol).
Methods: 513 patients with STR (mean age 75±13 years, 39% atrial STR, 58% severe) underwent complete two-, three-dimensional, and Doppler echocardiography.

Aims: Although an association between the systemic circulation and transaortic flow rate (TFR) is frequently hypothesized in patients with aortic stenosis (AS), it has not been demonstrated previously. We sought to explore the relationship between blood pressure (BP), vascular afterload measures, clinical history of hypertension, TFR, and survival in patients with severe AS (aortic valve area ≤ 1 cm²).
Methods And Results: We studied 323 patients ≥ 65 years (110 prospective, 213 registry analysis) who underwent transcatheter aortic valve replacement over a 5-year period.

Background: Metastatic tumours are the most common malignant tumours affecting the heart. Cardiac metastatic tumour progression is rapid, with no specific treatments available, and the prognosis is typically poor. Significant challenges remain in the diagnosis and treatment of cardiac metastases.

Total anomalous pulmonary venous return (TAPVR) is a high risk and rare cardiac malformation with a low prenatal detection rate and predicting obstruction in these cases is difficult. We sought to investigate fetal echocardiographic parameters associated with postnatal pulmonary venous obstruction (PPVO). We performed a retrospective review of 26 patients with TAPVR who had a fetal echocardiogram from 2010 to 2021.

This study examines how heart rate (HR) affects hemodynamics in a South African infant with Coarctation of the Aorta. Computed tomography angiography segments aortic coarctation anatomy; Doppler echocardiography derives inlet flow waveforms. Simulations occur at 100, 120, and 160 beats per minute, representing reduced, resting, and elevated HR levels.
