The variables of the learning curve for RAPN can be obtained earlier than the same variables for LPN. RAPN had a shorter OR time and WITs. The shorter WITs, earlier in the series, led to consistently lower fluctuations in GFR and preservation of the renal function. The learning curves for each procedure need to be re-evaluated at longer intervals to ensure their accuracy.

Wellens' syndrome is well-known for its critical stenosis of the proximal left anterior descending artery (LAD) with characteristic electrocardiographic findings of biphasic or deeply inverted T waves in V2-V6 under specific diagnostic criteria. Although the syndrome is known as a high-grade LAD lesion, its sequence of events can also be seen with the right coronary artery (RCA) and the left circumflex artery (LCX). This systemic review attempts to expand on these findings while analyzing the prevalence of Wellens' syndrome with the RCA and/or the circumflex artery. This study also comparatively indicated that Wellens' syndrome is seen in RCA and circumflex artery stenoses when present; the indication of the same medical management is warranted for effective treatment and survival. We extracted and analyzed 24 case reports each with an atypical presentation of acute coronary syndrome (ACS) and specific Wellens' syndrome pattern of electrocardiogram (ECG) presentation with critical stenosis in the LAD, RCA, and left circumflex artery. The risk of bias assessment was undertaken using internal risk analysis by utilizing medical libraries and certain search phrases to find research articles with the involvement of the LAD as opposed to the RCA and LCX in Wellens' syndrome. Based on the number of respective primary research articles found, a bias calculation was done on the reported respective coronary artery involvement.The finding of our systemic review confirms that Wellens' syndrome is a precordial lead disease with T wave abnormalities that present with critical stenosis of not only the LAD but also the RCA and circumflex artery.The result of our systemic review affirmed that although most Wellens' syndrome cases reported involve the stenosis of the LAD, the critical occlusion of the RCA and/or the circumflex artery was found with Wellens' syndrome pattern of ECG presentation, meaning that the sequence of events is not limited to the proximal LAD.

We present a rare case of fibromuscular dysplasia (FMD) manifesting in the mid to distal segment of the left anterior descending (LAD) artery, which led to the development of acute coronary syndrome (ACS) in our patient, highlighting the severe consequences of this vascular disorder. During the investigation of the patient's clinical symptoms, an unexpected incidental finding emerged, indicating bilateral FMD involvement of the renal arteries. This serendipitous discovery underscores the importance of comprehensive evaluation and thorough exploration when managing patients with FMD. We aim to shed light on the intriguing nature of FMD and emphasize the need for vigilant assessment to identify potential multi-vessel abnormalities, even beyond the primary affected site. We also aim to highlight the coronary artery manifestation of FMD as ACS and discuss its medical management.
