Myocardial ischemia caused by the synergistic effect of myocardial bridge and moderate stenosis: case report.

Background: Clinical events such as angina pectoris, acute coronary syndrome, and sudden death caused by myocardial bridge (MB) have attracted increasing attention. It is still a challenge to diagnose whether MB can cause the symptoms of patients with MB. For most MB patients, medication remains the primary treatment.

Extension of interval between adjacent pulse delivery cycles to deal with myocardial ischemia by intravascular lithotripsy: case report.

Background: Intravascular lithotripsy (IVL) represents a novel approach in the management of coronary calcification. This technique employs acoustic pressure waves, generated by a shockwave balloon, to effectively fracture both superficial and deep calcification in situ. The efficacy and safety of IVL have been convincingly demonstrated through the Disrupt CAD I-IV studies.

Intravascular lithotripsy: A novel option for severe calcification of coronary artery.

Background: Severe coronary artery calcification is associated with low success rate of interventional operation, perioperative adverse cardiac events, and poor prognosis, which is a major problem faced by operators. The existing therapy methods all have inherent limitations, such as unsatisfactory balloon crossability, inadequate balloon dilation, and so on. The emergence of intravascular lithotripsy (IVL) has brought the dawn of the treatment of calcified lesions by using unfocused acoustic pressure waves to fracture calcification in situ.
