Table 1 Organized timeline

From: Obstructive accessory mitral valve tissue in an adult patient: a case report

Three months earlier

Non-specific symptoms started (chest discomfort and exertional dyspnea)

Day 0

Visiting ER and admission to CCU

Day 1

Stabilizing vital signs and controlling symptoms/Management with metoprolol and O2

Day 2

TTE discovered a suspicious mass

Day 7

TEE emphasized the presence of accessory tissue

Day 14

Multi-slice CT studied the relation between the tissue and its neighboring anatomy and provided a primary impression of the coronary tree

Day 25

Coronary catheterization demonstrated multi-vessel disease with no associated anomaly

Day 40

CABG and surgical removal of the mass

Day 50

Biopsy showed fibrous tissue and TEE clarified normal PG across LVOT

  1. CABG coronary artery bypass graft, CCU coronary care unit, CT computed tomography, ER emergency room, LVOT left ventricular outflow tract, PG pressure gradient, TEE transesophageal echocardiography, TTE transthoracic echocardiography
