Functional Prosthetic Valve Dysfunction: An Underrecognized Cause of Elevated Transprosthetic Gradients

Haffane Fadwa, Elaakib Khaoula, Oudadda Soumaya, El Masrioui Joumana, El Karimi Saloua & El Hattaoui Mustapha · Cardiology and Angiology: An International Journal · 2026

Background: Elevated transprosthetic gradients are commonly considered a sign of prosthetic valve obstruction. However, certain haemodynamic or physiological conditions may result in increased gradients despite a structurally normal prosthesis. Recognizing these functional abnorm...

Cardiac Structural and Functional Alterations in End-stage Renal Disease : An Echocardiographic Study

Chadbellah Imane, El Fathi Asmaa, Ouaziz Mariam, Khzami Ranim, El Jamili Mohamed, El Karimi Saloua & El Hattaoui Mustapha · Cardiology and Angiology: An International Journal · 2026

Background: Cardiovascular disease accounts for approximately 45% of all-cause mortality in hemodialysis patients — a risk 10 to 20 times higher than in the general population. Despite the critical role of echocardiography in characterizing this cardiac burden, systematic echocar...

From Isolated Dyspnea to Catastrophic Mechanical Complication: Posteromedial Papillary Muscle Rupture Following Subtle Inferior STEMI

Chadbellah Imane, Ouaziz Mariam, El Fathi Asmaa, Ait Yahya Abdelkarim, El Jamili Mohamed, El Karimi Saloua & El Hattaoui Mustapha · Cardiology and Angiology: An International Journal · 2026

Background: Papillary muscle rupture (PMR) is a rare but rapidly fatal mechanical complication of acute myocardial infarction (MI) that may occur even after apparently limited ischemia. In the contemporary reperfusion era, its incidence is estimated between 0.05% and 0.26% of MIs...
