Managing Kartagener's Syndrome With Type II Respiratory Failure and Left-Sided Pneumothorax During the COVID-19 Pandemic: A Case Report.

Kartagener's syndrome is an autosomal recessive disorder with symptoms varying from chronic sinusitis to bronchiectasis and situs inversus (a congenital condition in which the visceral organs are located in an opposite location). We describe a rare and complicated case of a 40-year-old female patient who presented to the emergency room with significant chest congestion and Kartagener's syndrome. This case demonstrates the value of individualized and proactive care as well as the challenge of managing this illness, particularly when it coexists with type II respiratory failure related to pneumothorax.

The prevalence, angiographic profile and clinical features, management, and outcomes of coronary artery perforation secondary to percutaneous coronary interventions in Pakistan: a retrospective cohort study.

Coronary artery perforation (CAP) is a rare entity that is often fatal. The mortality rates reported as high as up to 21% hence prompt diagnosis, intervention, and treatment are paramount to survival for such patients. Several factors may predispose a patient to coronary artery intervention including chronic total occlusion, severe calcification and tortuosity, aggressive use of oversized balloons and stents, and use of athero-ablative devices. Therefore, it is significant to have an insight related to it as despite being rare, it is one of the most feared complications of percutaneous coronary intervention (PCI). Method: We conducted a retrospective study of the patients who have undergone PCI at our institution from January 2015 to December 2021. During this duration, all the patients who had developed CAP based on angiographic review during the PCI were selected. The demographic, clinical, angiographic, procedure-related features, management of the CAP, and in-hospital and follow-up outcomes were gathered. Result: Thirty-five thousand fifty-nine patients underwent PCI among which, only 93 (0.26%) patients were complicated with (CAP. Fifty-eight (62.4%) patients were in the 50-70 years age range. The most common vessel involved was the left anterior descending (36.5%) followed by the right coronary artery (32.3%). The angiographic calcification was present in 51.6% of patients, significant tortuosity greater than 90° was seen in 48.4% of patients, chronic total occlusion was observed in 42% of patients and In-stent restenosis was found in 8.6% patients. The highest mortality of four patients was seen in the CAP involving the right coronary artery. Conclusion: Mostly the CAP involves large vessel perforations however both, the distal and large vessel perforations are related to the increased incidence of adverse clinical results which indicates the significance of the prevention and early identification and treatment of the perforation.
