T and Small Protrusion (TAP) Technique in Bifurcations: Coronary Artery Disease in Acute Myocardial Infarction Patients after COVID-19 Pneumonia

Round 1

Reviewer 1 Report

The authors submited a case report of coronary artery bifurcation lesions management. The case report is well written and composes of historical aspect of the issue, clear description of the case along with discussion around of desicion-making and choice of the treatment. The presentation sound well, while I would like recommend the following.

The authors should give more information regarding pre- and post-PCI treatment and evaluate an impact of coronary anatomy on a risk of post-PCI complication(s) icluding microvascular obstruction etc.

Author Response

Point 1 - The authors should give more information regarding pre- and post-PCI treatment and evaluate an impact of coronary anatomy on a risk of post-PCI complication(s) including microvascular obstruction etc.

Response to Reviewer 1 Point 1 – We included in our Case Report information about pre- and post-PCI pharmacological treatment. We also included the assessment of risk stratification for 30-days mortality and MACE for this patient. We added the evaluation of risk of post-PCI complications, according to the patient’s coronary anatomy. Thank you!
