The purpose of this study is to summarize the results of percutaneous nephrolithotomy (PCNL) for renal stones following failed extracorporeal shockwave lithotripsy (SWL), and to investigate the effect of previous SWL on the performances and morbidities of subsequent PCNL. Sixty-two patients with a history of failed SWL who underwent PCNL on the same kidney (group 1) were compared to 273 patients who had received PCNL as first treatment choice (group 2). Patient demographics, stone characteristics, operative findings, and complications were documented and compared. Groups 1 and 2 had similar patient demographics and stone characteristics. Mean time to establish access was comparable in both groups (10.5 ± 4.2 vs. 9.6 ± 4.5 min, p = 0.894). Time required to remove stones and total operative time were longer in group 1 (71.5 ± 10.3 vs. 62.3 ± 8.6 min, p = 0.011 and 95.8 ± 12.0 vs. 80.6 ± 13.2 min., p = 0.018, respectively). Group 1 had lower clearance rate compared to group 2 (83.9 vs. 93.4 %, p = 0.021), while postoperative complications were similar in both groups. Scattered stone fragments buried within the tissues made the procedure more difficult for stone fragmenting and extracting, which lead to longer operative time and inferior stone free rate. However, the PCNL procedure was safe and effective in patients with failed SWL. The risk of complications was similar and clearance rate was encouraging.

Comparison of Outcomes of Patients With Versus Without Chronic Liver Disease Undergoing Percutaneous Coronary InterventionIstanbuly, Sedralmontaha, Matetic, Andrija, Mohamed, Mohamed O., Panaich, Sidakpal, Velagapudi, Poonam, Elgendy, Islam Y., Paul, Timir K., Alkhouli, Mohamad, Mamas, Mamas A. 01 October 2021 (has links)
There are limited data on the outcomes of chronic liver disease (CLD) patients admitted for percutaneous coronary intervention (PCI). All PCI hospitalizations from the Nationwide Inpatient Sample (2004 to 2015) were analyzed and stratified by the presence, cause and severity of CLD, as well as the indication for PCI. Multivariable logistic regression analysis was performed to determine the adjusted odds ratios (aOR) of in-hospital adverse outcomes in patients with CLD compared with those without CLD. Among 7,296,679 PCI admissions, 54,368 (0.7%) had a CLD diagnosis. Among patients with CLD, 36,853 (67.8%) had severe CLD. Patients with CLD had higher likelihood of adverse outcomes including major adverse cardiovascular and cerebrovascular events (MACCE) (aOR 1.25, 95%CI 1.20 to 1.30), mortality (aOR 1.43, 95%CI 1.35 to 1.51), major bleeding (aOR 2.22, 95%CI 2.12 to 2.32). When accounting for severity, only severe CLD subgroup was more likely to have MACCE and all-cause mortality compared to no-CLD patients (p <0.001). Among CLD etiologic subgroups, those with ‘alcohol-related liver disease’ and ‘other CLD’ were consistently more likely to develop MACCE, all-cause mortality and major bleeding in comparison to no-CLD patients, while ‘chronic viral hepatitis’ subgroup had only increased odds of major bleeding (p <0.001). In conclusion, CLD patients admitted for PCI are more likely to have worse in-hospital outcomes, particularly in the severe CLD subgroup and ‘alcohol-related liver disease’ and ‘other CLD’ etiologic subgroups.

Comparison of Rotational with Orbital Atherectomy During Percutaneous Coronary Intervention for Coronary Artery Calcification: A Systematic Review and Meta-AnalysisSawant, Abhishek C., Panchal, Hemang, Radadiya, Dhruvil, Pomakov, Alexander, Tse, Gary, Liu, Tong, Sridhara, Srilekha, Rodriguez, Janelle, Prakash, Meghana Prakash Hiriyur, Kanwar, Nidhi, Kumar, Arnav, Banerjee, Kinjal, Wiesner, Philipp, Pershad, Ashish 01 April 2020 (has links)
Background: Percutaneous coronary intervention (PCI) outcomes for patients with significant calcification have been consistently inferior compared to patients without significant calcification. Procedural success and long-term outcomes after PCI have been worse in patients with severe coronary calcium. Objective: A Bayesian meta-analysis of outcomes comparing rotational atherectomy (RA) with orbital atherectomy (OA) was performed. Methods: PubMed, Embase, and Cochrane Library databases were searched through 30th November 2018 and identified 4 observational studies. Results: The primary end-point, Major Adverse Cardiac Event (MACE) composing of death, MI and stroke at 1 year was more likely with RA (OR = 1.61; 95% CI: 1.11–2.33; p = 0.01) as compared to OA. The driver of the difference in MACE between the two groups was a statistically significant difference in mortality favoring OA (OR = 4.65; 95% CI: 1.36–15.87; p = 0.01). Peri-procedural MI, the other component of the primary end-point was 1.3 times more likely in the RA arm (OR = 1.35; 95% CI 0.95–1.92; p-0.09) and was not statistically different between the groups. The odds of a vascular complication were not different in the two groups (OR = 1.26; 95% CI: 0.73–2.17; p = 0.41). In an adjusted Bayesian analysis, mortality (OR = 3.69; 95% CI: 0.30–38.51), MACE (OR = 1.68; 95% CI: 0.55–5.49), MI (OR = 1.42; 95% CI: 0.50–4.29) and dissections/perforations (OR = 0.38; 95% CI: 0.10–1.38) were not different in RA and OA groups. Conclusion: Our study is the first published Bayesian meta-analysis comparing MACE and peri-procedural outcomes in RA compared to OA. These findings lay the foundation for a randomized comparison between the two competing technologies.

Early Post-Percutaneous Coronary Intervention Chest Pain: A Nationwide Survey on Interventional Cardiologists' PerspectiveTaha, Yasir, Bhatt, Deepak L., Mukherjee, Debabrata, White, Christopher J., Treece, Jennifer M., Brilakis, Emmanouil S., Banerjee, Subhash, Paul, Timir K. 01 December 2020 (has links)
Background: Early post-percutaneous coronary intervention chest pain (EPPCP) appears to be a common clinical phenomenon. EPPCP has not been fully explained or studied in the literature despite the abundance of clinical trials on percutaneous coronary intervention (PCI). The objective of this questionnaire-based survey is to assess the current perception of EPPCP among practicing interventional cardiologists nationwide. Methods: A survey questionnaire was designed utilizing the Survey Monkey tool to address the perceptions and current practices regarding key aspects of EPPCP among interventional cardiologists. The survey was sent to the interventional cardiologists via email. Results: The survey questionnaire regarding EPPCP was provided to 2615 practicing interventional cardiologists and resulted in 623 total survey responses, with 503 of those respondents completing all eight survey questions. A total of 50.2% of the interventional cardiologists perceive that the incidence of EPPCP is 5–10%, and 57.5% consider that repeat angiography or PCI is rarely needed (1 in 1000 cases). A total of 47.1% of the participants think that EPPCP is due to transient microvascular dysfunction, while 39% perceive it as a different entity requiring a different approach. When asked about developing a standardized labeling for the phenomenon of EPPCP, 34.8% of responders indicated that they believe EPPCP should be labeled as a benign form of chest pain/angina, and 28% preferred to describe EPPCP in non-standardized terms. Among interventional cardiologists, 80% thought that the treatment of this entity is a combination of reassurance and vasodilators and, without ischemic ECG changes, medical management is appropriate. Conclusion: A total of 72% of interventional cardiologists in our survey preferred to label EPPCP as standard nomenclature to facilitate communication between healthcare providers, patients and families in a consistent way. There is a diversity of opinion regarding EPPCP, no standard nomenclature, and no guideline to standardize practice. Further large-scale prospective studies are needed to better understand the pathophysiological mechanisms, optimal management strategies, prognostic implications, and clinical reporting of EPPCP.

Outcomes Following Percutaneous Coronary Intervention Before, During, and After Transition to a Default Transradial Approach at a Veterans Affairs Medical CenterBagai, Jayant, Bhuiyan, Azad R., White, Christopher J., Mukherjee, Debabrata, Paul, Timir K. 01 August 2020 (has links)
Transradial coronary intervention (TRI) lowers bleeding and mortality compared with transfemoral coronary intervention (TFI). There are limited data on outcomes as TFI operators transition to a default TRI practice. The aim of this study was to assess TFI and TRI outcomes before, during, and after the year TRI was first learned by femoral operators. Patients undergoing percutaneous coronary intervention (PCI) at a Veterans Affairs Medical Center from 2006 to 2012 were included. In 2009, TRI was learned by all operators and then used as the default PCI approach from 2010 to 2012. Baseline characteristics and outcomes were collected. Predictors of major bleeding, major adverse cardiovascular events (MACE), and mortality were determined by multivariable analysis; 1192 veterans were included. TRI rates were 9% (2006-2008), 65% (2009), and 90% (2010-2012). Incidence of 1-year MACE and mortality was 5.4% and 3.9%, respectively, in 2009, and 5.6% and 3%, respectively, during 2010 to 2012. Major bleeding remained at <1%. Age, glycoprotein IIb/IIIa inhibitors, and ST-elevation myocardial infarction were independently associated with major bleeding, whereas TRI was protective. Transition to default TRI is feasible over a short time period and associated with low rates of MACE and mortality and very low rate of major bleeding.

Blinding and Controls in Postoperative Percutaneous Pain ManagementGreen, Kemble L., Glenn, L. Lee 01 December 2013 (has links)
Excerpt: Gavronsky, Koeniger-Donohue, Steller, and Hawkins (2012) concluded that, 48 hours after major pelvic surgeries for cancer, the women in their study experienced equivalent pain relief from either manual acupuncture or percutaneous electrical nerve stimulation. This statement was not supported by the study data because of the lack of blinding and insufficient controls. Despite the numerous strengths of the study, due to weaknesses in the study design with regard to blinding and control groups, the addition of acupuncture to percutaneous electrical nerve stimulation should not yet be ruled out as a method of obtaining enhanced pain relief.
